Using Adobe XD and Platforma Web Wireframe Kit to prototype an iOS app

November 23, 2017 by Simon

I have blogged about using Adobe XD to prototype mobile apps. Recently, I found an attractive collection of ready to go Wireframe screens from Proforma to use alongside Apple UI Kit elements in Adobe XD

Check Out Platforma

Platforma has been in the industry for years providing developers with prototype products for Mobile, Web and HTML templates.  Check out https://greatsimple.io/ for other prototyping products.

You can buy (or try) versions of Platforma at https://platforma.ws/#buy Below are screenshots from the Bundle version.

Performa has loads of ready to go samples screens that you can use in Adobe XD like..

  • Start Screens
  • Sign up Screens
  • Walkthrough Screens
  • Loading Screens
  • Feed Screens
  • Activity Screens
  • Profiles Screens
  • Posts Screens
  • Chats Screens
  • Contacts Screens
  • Search Screens
  • Lists Screens
  • Settings Screens
  • Create Screens
  • Catalog Screens
  • Discover Screens
  • Products Screens
  • Shopping Carts
  • Check Out Screens
  • Filters Screens
  • Navigation Screens
  • Maps Screens
  • About Screens
  • Popovers Screens
  • Photos Screens
  • Media Screens
  • Social Screens
  • E-commerce Screens
  • Charts and More (there are over 100 screens)

Adobe XD, Platforma and iOS Prototypes

The post below will focus on creating iOS prototypes using Adobe XD and Platforma Wireframe kits.

Other posts will focus on creating Android, and Web Prototypes etc. After you purchase Platforma, you can download a zip file (I have the bundle) containing all related design files.

Tip: Save your activation code if you eceive one.

Download

Extract the Zip file.

Zip

Files are located in each products folder (I will focus on XD in iOS assets until I learn the others).

PLATFORMA BUNDLE FILES

Adobe XD iOS assets are in two files.

Adobe XD

You can now open either Platforma .xd file to view prototype elements available.

You may get a Fonts Missing dialogue (install the fonts and the error goes away).

fyi

  • I downloaded Roboto font from here
  • SF UI * font can be downloaded from here
  • Apple San Francisco Font from here.

All font packs are free, the Apple San Francisco font needs you to run an install wizard, SF UI needs you to download and install TTF file from GitHub, Roboto needs you to double-click on a number of TTF files to install them in your fonts library.

The fonts are now installed (verified in my fonts app on OSX).

Fonts

I am now free to open the iOS “Platforma for iOS – Categories.xd” file that came from Proforma.

Performa iOS Categories (Zoomed Out)

Oh my, there are loads of sample screens and elements you can use in an app prototype (I’d count them but I’d be here all day, I had to zoom out to 2.5% to see them all).Platforma iOS

Now time to open the second file (“Platforma for iOS – Demos.xd”)

Performa iOS Categories (Zoomed In on Maps)

I had a look at the sample “Maps” screens and they are amazing.

Maps

Performa iOS Demos (Zoomed Out)

Here is a complete zoomed out view of the “Platforma for iOS – Demos.xd” file.

Platforms settings 1

Performa iOS Demos (Zoomed in on Social Samples)

Here is a sample of some of the screens in the Social category in the “Platforma for iOS – Demos.xd” file.

Let’s Start an App Prototype in Adobe XD

I open the “./Platforma for iOS/XD/Platforma for IOS/Platforma for iOS – Categories.xd” and “./Platforma for iOS/XD/Platforma for iOS – Demos.xd” xd files that you downloaded from https://platforma.ws/

Also, start a new iOS blank project in Adobe XD.

New Project

I positioned windows so I could see all Adobe XD projects.

Windows

Tip: If you are using the Apple iOS (or Android etc) UI components then you can open them too (see my Adobe XD guide to see how to get the oficial iOS controls from Apple).

iOS Controls

Personally, I would suggest before you start prototyping that you have a “validated list” of things that you want to prototype (if you are designing a prototype for a client then ask them what they want). Check out the awesome http://joinagile.com/lean-and-mean-agile-podcast/ for tips on Collecting, grooming, prioritizing app tasks. Don’t waste time developing unwanted features. Manage tasks around Outcomes and not tasks. I have blogged about developing software and staying on track and how to get feedback for your ideas.

Also, I have a so you have an idea for an app graphic and blog posts on Atlaz.io BETA Project Management Tool For Cross-Functional Teams the Trello and Atlassian JIRA Killer? and How to develop software ideas. I would suggest you listen to the Lean and Mean Agile Podcast to get extra product backlog grooming, prioritization tips etc.

TIP: I use the MoSCoW method for capturing and prioritizing tasks.

snip from: https://en.wikipedia.org/wiki/MoSCoW_method
Must have
Requirements labelled as Must have are critical to the current delivery timebox in order for it to be a success? If even one Must have requirement is not included, the project delivery should be considered a failure (note: requirements can be downgraded from Must have, by agreement with all relevant stakeholders; for example, when new requirements are deemed more important). MUST can also be considered an acronym for the Minimum Usable Subset.
Should have
Requirements labelled as Should have are important but not necessary for delivery in the current delivery timebox. While Should have requirements can be as important as Must have, they are often not as time-critical or there may be another way to satisfy the requirement so that it can be held back until a future delivery timebox.
Could have
Requirements labelled as Could have are desirable but not necessary, and could improve user experience or customer satisfaction for little development cost? These will typically be included if time and resources permit.
Won’t have (this time)
Requirements labelled as Won’t have been agreed by stakeholders as the least-critical, lowest-payback items, or not appropriate at that time. As a result, Won’t have requirements are not planned into the schedule for the next delivery timebox. Won’t have requirements are either dropped or reconsidered for inclusion in a later timebox. (Note: occasionally the term Would like to have is used; however, that usage is incorrect, as this last priority is clearly stating something is outside the scope of delivery).

end snip.

Starting your Prototype in Adobe XD

Based on your MoSCoW list you can (I do) create empty screens ( I usually add a label in the top left indicating the screens MoSCoW status so I can prototype needed features now and start planning future versions later from the one prototype file). I am not a big fan of using multiple app prototype files.

Moscow Screens

Now you can copy and paste in example screens over the empty screens.

Within minutes you can have a nice mockup of your app using Adobe XD and Platforma assets.

Drag as needed, change as needed.

Design your app

Customizing sample screens

Of course, you can edit the sample screens and rename, add, remove or change individual items in Adobe XD (Nice work Platforma/Adobe). Ignore the Yellow “Should Have” on the screen below, it looks out of place but I get in the habit of adding a floating “Must Have”, “Should Have”, “Could Have” and Won’t Have” labels to screens.

Editing

Preview

You can preview the rough prototype in Adobe XD on your desktop or on a real mobile device.

Don’t forget to wire up screens to generally goto and return to the main screen.

Wire up a prototype

Or you can wire up individual screen elements to go to different screens. You will need to be in Prototype mode in XD first.

Button

If you saved to the Adobe Cloud you can now open the prototype app on the Adobe XD app on a mobile device (or simulate it in Adobe XD on the desktop). Open Adobe XD on your mobile device and open your project from your Adobe Creative Cloud folder.

Mobile app

You can now view fabulous looking application prototypes on a mobile device screen with minimal invested time and effort.

Testing

Conclusion

I am very impressed with the https://platforma.ws Wireframe Kit, I’d strongly recommend app developers buy a copy and use the pre-setup templates look impressive and will save you loads of time (no more messing with UI Kits to make app prototypes look good). I can’t wait to check out and review the other assets in the Full Platforma Bundle.

Infographic: So you have an idea for an app

October 31, 2017 by Simon

I created this graphic as I was asked by multiple people how to develop an app. This does not include tips on coding but many people with the non-technical prerequisites to building an app.

I hope this graphic helps someone (It’s my first infographic/decision flow image, feedback welcome).

 - Add user personas and Epic, Story and Task stages.
 - How to capture good stories (and validated ideas (landing pages/interviews/problems/value/painpoints)

Define the problem(s) (pain points)

Before you start coding, do list your app requirements (problem’s to solve (pain points)).

Atlassian JIRA or Trello can help with this. I personally use (and like) Atlaz.io (now Hygger), I reviewed the BETA here).

Using Trello lists are also a simple way to capture tasks/ideas.

ListMore on these Read more here also read my Atlaz.io BETA Preview here.

Nothing beats pen and paper too.

Notepad

Moscow Prioritization

Must-Have Should-Have, Could-Have and Won’t-have are buckets you should sort ideas into. If you have trouble moving items away from Must to Should, Could or Won’t then assign a fictitious monetary value to spend on each item and that will help you decide what is more important.

Read this MoSCoW Method article at Wikipedia: https://en.wikipedia.org/wiki/MoSCoW_method

Managing MoSCoW tasks on paper is OK if you do not want to use planning software.

More

Read my guide on how to prototype apps with Adobe XD guide here.  You can also Prototype a Web app with Platforma (review here).

Read my post on how to develop software and stay on track.

Research

Do research your idea for market fit/need, competition, complexity, legal and validate ideas early. It’s best to find out early that Google will quote $60,000+ TAX a year to allow you to use Google map’s in your app early, then you can use https://www.mapbox.com for $499 a year.

Do you have competition?

Some people say “don’t develop an app that already exists”. Why would you develop a new Uber app? Henry Ford did make a new transportation mode when people were happy with horses, other car manufacturers like Tesla are moving in on the space so don’t be discouraged.

Landing Page

A landing page with a signup form (Newsletter and Register Interest) form is a good way to validate ideas and get feedback early (I would suggest you use a free Mainchimp signup form, a generated website with Platforma on a $5/m server for quick results). There is no point coding and launching to crickets.

Do you have an app Prototype or Mock-Up?

This is very important and easy step.  Programs like Adobe XD CC  (read my guide here) and Balsamiq can help you prototype an app, Platforma can help you prototype web apps.

Wire up a prototype

Drag and Drop

Have you validated your idea (app) with end-users?

If you don’t do this you are mad.  Watch this video to see lessons learned from Trades Cloud.

Is this app idea a hobby (passion)?

This can help you limit costs and expectations.  Cheap serves exist (read here and here).

Do you have time to develop/manage this?

Developing and managing an app and planning (paying for) development cycle can be time-consuming and mentally draining.

Can you code?

Do you need to hire developers or learn to code?  Blog post coming soon on how to hire coders.

Do you have funds?

Having funds on hand to set up and build an app is very important.

Do you want to hide developers (or get Venture Capital)?

This can help you get moving but you will have to give away a slice of the profits and or IP, managing mentors and VC’s can be tiresome.

Have you set failure criteria (post-mortem)?

Read this page on lessons learned from over 200 startup failures, save your favourites.  Having realistic goals and limits is a wise idea, do stop when you reach preset limits.

Do you have a business case?

There is plenty of business case generator template’s,  you will want to document some of the following.

  • What is your apps Purpose – App X will be..
  • What is your Mission Statement – App X will..
  • Who are your Target Customers – Retail..
  • Who are the Early Adopters – Retail..
  • What Problems does your app solve – App X will..
  • What Milestones will your app go through – iOS, Android, Apple TV, Web etc..
  • What Existing solutions exist – App: A, B and C..
  • How does your app Solve your customer’s problems (pain points) – App X will..
  • How will your app Find customers – Word of Mouth, Referrals, Advertisements?
  • What is your Revenue model – Sales, Ad’s, Subscriptions?
  • What is your apps Goal statement – App X will hit X users in X?
  • What are your apps Failure points – If app X does not reach X or monthly costs reach Y….
  • What is your Marketing message – App X will..
  • What is your apps Metrics – iOS, Android, Apple TV apps..
  • What is your Unfair Advantage – Why will you succeed over others?

Are you using a project management methodology?

Proven Methodology can help you develop software and stay on track, software like Atlaz, JIRA or Trello are highly recommended tools. Capturing ideas and processing feedback in tools is very important.

Before you code (or hire coders) use source code versioning software like GitHub and Bitbucket (guides here and here).  You want to retain the code and insist on owning it.

Product Goal

Simon Sinek has a good video on companies (or Products) being in a finite or infinite game.

Are you in full control of your development stack?

If you are not a developer you may not care if you are in control, but you will if there are issues with hired developers or issues with service providers.  I moved from CPanel to self-managed servers, moved from IBM Cloudant to Digital Ocean to AWS then Vultr servers where I can have full control or scalability, features, security and costs.

Can you forecast the costs?

Lowering cost and boosting performance is important and having spare money is a good thing.

I read recently that  Telsla is burning through $6,000 a minute and is forecast to need something like 2 billion dollars in the next 2 years. Software as Service platforms will drain your budget quick (they do take on some risk and maintenance tasks), is this worth it?

Mark Fedin (CEO and Co-founder at Atlaz) has a great post on the topic of viability Stop Dabbling At Startups .

Are you using the right tech?

Don’t be afraid of changing tech along the way, you may start with MySQL and move to MongoDB, Redis, Oracle ot MSSQL database servers etc.

Do you have systems to capture customer feedback?

Self-explanatory, you are solving customer problems, right? You will pivot in the first year (trust me).

What is your revenue/sales model?

If you don’t know how to make money then don’t make an app (apps are expensive to code and maintain).

Are you prioritizing task?

I have blogged about this before, do use the tools to stay on track.

Quick guide to using Adobe XD CC to design a prototype iOS app.

October 25, 2017 by Simon

Adobe has introduced (v1.0.x) Adobe XD CC, Adobe claims you can turn your best ideas into beautiful experiences — fast. Let’s give it a try.

Adobe Experience Design (Beta) is now Adobe XD CC. You can now design, prototype, and share amazing user experiences for websites, mobile apps, and more — all in the same app. Adobe XD CC is similar to Balsamic Mockup software.

Adobe XD Intro

Here is a great video demoing Adobe XD.

Install Adobe XD

If you don’t already have Adobe CC installed you can download a trial here. If you are wanting to install on Windows you will need Windows 10 (Anniversary Edition). Adobe has minimum system requirements listed here.

Install XD

Start a Project

Create a Project

After you start an iOS project you will be looking for controls to add to your prototype. Adobe XD CC offers where you can download UI Kits direct from vendors (a shame when you are used to XCode or Visual Studio having controls preloaded).

Installing the Apple UI Design Resources

You will need to download the Apple UI Design Resources for Design XD from the Apple site (use the menu in the screenshot below or click here), they do not come with Adobe XD CC.

Apple UI Design Resources

Here is more information on using Adobe XD CC UI Kits.

Download the iOS 11 UI resources for Adobe XD CC from the Apple site.

Download resources from Apple site

You can now extract the iOS resource files from Apple for use in Adobe XD projects.  When iOS 12 and Android 9 comes out you can download new UI Kits.

Extract Files

Once you extract the files from the zip file, run the ./iOS-11-AdobeXD/Fonts/San Francisco Pro.pkg file to install iOS 11 font on yoir system.

I could not find a way to install the UI Kits permanently into Adobe XD CC (Searching revealed you need to open templates (as a separate process or open file in Adobe XD (double-click on the file)) and paste elements into your project). This seems clunky.

Install UI Kits

Why use Adobe XD

You can use Adobe XD to prototype interfaces around the common activities, a person may perform while using the apps you are prototyping. You can design an app’s onboarding, intro or user screens before actually developing the app.

http://bundle.greatsimple.io/

http://bundle.greatsimple.io/

http://bundle.greatsimple.io/

https://platforma.ws/ also has an extension for Adobe XD to allow you to get a  prototype fast with ready to go layout elements. I will write a new blog post using https://platforma.ws/ in Adobe XD.

iOS Prototype Project

Let’s create an iOS project. Start a new iPhone 6/7 Project AND open up a UI template file in a second Adobe XD program (e.g ./iOS-11-AdobeXD/UI Elements + Design Templates + Guides/UIElements+DesignTemplates+Guides.xd).

Now you can drag and drop elements from the UI template (from Apple) into an XD CC app prototype project

Prototype Project

TIP: Apple has a great site explaining how you can design and deliver apps (open the Apple Human Interfaces – iOS Design Themes page here). Apple also has assets and guidelines available for marketing your apps here.

To make buttons interactive you will need to click the Prototype tab and then drag the blue tabs to the right of interactive elements to the target screens.

Make Interactive

You can learn more on making interactive prototypes here.

Tip: Don’t forget to add interactive links back to the home screen.

You can then press the play button to preview the app prototype simulated in software.

Simulate

Export

You can now save and export your prototype app project to PNG, PDF, Web or other formats to others to send for review.

Export

Adobe XD is big on saving to the Adobe Cloud allowing others to see changes in real-time.  If you have linked assets in your prototype project (say Photoshop files) anyone viewing an XD prototype on the Adobe Cloud can automatically see changes in real-time (see then Adobe XD intro video above).

Running Prototypes on Real Devices

I was able to install Adobe XD app onto iOS, log in with my Adobe ID and the prototype popped up when I connected my iOS device to my Mac. More info here.

I was able to install the Android Adobe XD app and also sync a prototype app (Android was a bit slower to find the project but still the same process as iOS).

30 Adobe XD CC/Adobe Comp tablet app tips

Conclusion

Pros

  • Adobe XD comes with Adobe CC.
  • Ope to feature enhancements.
  • Loads or 3rd party tools and user forums.
  • Automatic detection of duplicate actions (copy and paste grid items) and suggestion of repeating grids by pressing Command+R.

Cons

  • Unable to import UI Kits permanently into Adobe XD (I have to run multiple XD apps and paste UI elements between). Why would I no just stick with Adobe Photoshop?
  • Placement of UI elements like fonts feels clunky when compared to XCode and Visual Studio.
  • Duplicating prototype forms was not an option in the right-click (copy and Paste worked and so did ALT+Drag).

On the positive side, Adobe is openly allowing people to suggest and vote on features here https://adobexd.uservoice.com

But with Adobe XD you have the flexibility of having a design and prototyping product in one package with new monthly features.

Securing Ubuntu in the cloud

August 9, 2017 by Simon

It is easy to deploy servers to the cloud within a few minutes, you can have a cloud-based server that you (or others can use). ubuntu has a great guide on setting up basic security issues but what do you need to do.

If you do not secure your server expects it to be hacked into. Below are tips on securing your cloud server.

First, read more on scanning your server with Lynis security scan.

Always use up to date software

Always use update software, malicious users can detect what software you use with sites like shodan.io (or use port scan tools) and then look for weaknesses from well-published lists (e.g WordPress, Windows, MySQL, node, LifeRay, Oracle etc). People can even use Google to search for login pages or sites with passwords in HTML (yes that simple).  Once a system is identified by a malicious user they can send automated bots to break into your site (trying millions of passwords a day) or use tools to bypass existing defences (Security researcher Troy Hunt found out it’s child’s play).

Portscan sites like https://mxtoolbox.com/SuperTool.aspx?action=scan are good for knowing what you have exposed.

You can also use local programs like nmap to view open ports

Instal nmap

sudo apt-get install nmap

Find open ports

nmap -v -sT localhost

Starting Nmap 7.01 ( https://nmap.org ) at 2017-08-08 23:57 AEST

           Raw packets sent: 0 (0B) | Rcvd: 0 (0B)

Limit ssh connections

Read more here.

Use ufw to set limits on login attempts

sudo ufw limit ssh comment 'Rate limit hit for openssh server'

Only allow known IP’s access to your valuable ports

sudo ufw allow from 123.123.123.123/32 to any port 22

Delete unwanted firewall rules

sudo ufw status numbered
sudo ufw delete 8

Only allow known IP’s to certain ports

sudo ufw allow from 123.123.123.123 to any port 80/tcp

Also, set outgoing traffic to known active servers and ports

sudo ufw allow out from 123.123.123.123 to any port 22

Don’t use weak/common Diffie-Hellman key for SSL certificates, more information here.

openssl req -new -newkey rsa:4096 -nodes -keyout server.key -out server.csr
 
Generating a 4096 bit RSA private key
...

More info on generating SSL certs here and setting here and setting up Public Key Pinning here.

Intrusion Prevention Software

Do run fail2ban: Guide here https://www.linode.com/docs/security/using-fail2ban-for-security

I use iThemes Security to secure my WordPress and block repeat failed logins from certain IP addresses.

iThemes Security can even lock down your WordPress.

You can set iThemes to auto lock out users on x failed logins

Remember to use allowed whitelists though (it is so easy to lock yourself out of servers).

Passwords

Do have strong passwords and change the root password provided by the hosts. https://howsecureismypassword.net/ is a good site to see how strong your password is from brute force password attempts. https://www.grc.com/passwords.htm is a good site to obtain a strong password.  Do follow Troy Hunt’s blog and twitter account to keep up to date with security issues.

Configure a Firewall Basics

You should install a firewall on your Ubuntu and configure it and also configure a firewall with your hosts (e.g AWS, Vultr, Digital Ocean).

Configure a Firewall on AWS

My AWS server setup guide here. AWS allow you to configure the firewall here in the Amazon Console.

Type Protocol Port Range Source Comment
HTTP TCP 80 0.0.0.0/0 Opens a web server port for later
All ICMP ALL N/A 0.0.0.0/0 Allows you to ping
All traffic ALL All 0.0.0.0/0 Not advisable long term but OK for testing today.
SSH TCP 22 0.0.0.0/0 Not advisable, try and limit this to known IP’s only.
HTTPS TCP 443 0.0.0.0/0 Opens a secure web server port for later

Configure a Firewall on Digital Ocean

Configuring a firewall on Digital Ocean (create a $5/m server here).  You can configure your Digital Ocean droplet firewall by clicking Droplet, Networking then Manage Firewall after logging into Digital Ocean.

Configure a Firewall on Vultr

Configuring a firewall on Vultr (create a $2.5/m server here).

Don’t forget to set IP rules for IPV4 and IPV6, Only set the post you need to allow and ensure applications have strong passwords.

Ubuntu has a firewall built in (documentation).

sudo ufw status

Enable the firewall

sudo ufw enable

Adding common ports

sudo ufw allow ssh/tcp
sudo ufw logging on
sudo ufw allow 22
sudo ufw allow 80
sudo ufw allow 53
sudo ufw allow 443
sudo ufw allow 873
sudo ufw enable
sudo ufw status
sudo ufw allow http
sudo ufw allow https

Add a whitelist for your IP (use http://icanhazip.com/ to get your IP) to ensure you won’t get kicked out of your server.

sudo ufw allow from 123.123.123.123/24 to any port 22

More help here.  Here is a  good guide on ufw commands. Info on port numbers here.

https://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers

If you don’t have a  Digital Ocean server for $5 a month click here and if a $2.5 a month Vultr server here.

Backups

rsync is a good way to copy files to another server or use Bacula

sudo apt install bacula

Basics

Initial server setup guide (Digital Ocean).

Sudo (admin user)

Read this guide on the Linux sudo command (the equivalent if run as administrator on Windows).

Users

List users on an Ubuntu OS (or compgen -u)

cut -d: -f1 /etc/passwd

Common output

cut -d: -f1 /etc/passwd
root
daemon
bin
sys
sync
games
man
lp
mail
news
uucp
proxy
www-data
backup
list
irc
gnats
nobody
systemd-timesync
systemd-network
systemd-resolve
systemd-bus-proxy
syslog
_apt
lxd
messagebus
uuidd
dnsmasq
sshd
pollinate
ntp
mysql
clamav

Add User

sudo adduser new_username

e.g

sudo adduser bob
Adding user `bob' ...
Adding new group `bob' (1000) ...
Adding new user `bob' (1000) with group `bob' ...
Creating home directory `/home/bob' ...
etc..

Add user to a group

sudo usermod -a -G MyGroup bob

Show users in a group

getent group MyGroup | awk -F: '{print $4}'

This will show users in a group

Remove a user

sudo userdel username
sudo rm -r /home/username

Rename user

usermod -l new_username old_username

Change user password

sudo passwd username

Groups

Show all groups

compgen -ug

Common output

compgen -g
root
daemon
bin
sys
adm
tty
disk
lp
mail
proxy
sudo
www-data
backup
irc
etc

You can create your own groups but first, you must be aware of group ids

cat /etc/group

Then you can see your systems groups and ids.

Create a group

groupadd -g 999 MyGroup

Permissions

Read this https://help.ubuntu.com/community/FilePermissions

How to list users on Ubuntu.

Read more on setting permissions here.

Chmod help can be found here.

Install Fail2Ban

I used this guide on installing Fail2Ban.

apt-get install fail2ban

Check Fail2Ban often and add blocks to the firewall of known bad IPs

fail2ban-client status

Best practices

Ubuntu has a guide on basic security setup here.

Startup Processes

It is a good idea to review startup processes from time to time.

sudo apt-get install rcconf
sudo rcconf

Accounts

  • Read up on the concept of least privilege access for apps and services here.
  • Read up on chmod permissions.

Updates

Do update your operating system often.

sudo apt-get update
sudo apt-get upgrade

Minimal software

Only install what software you need

Exploits and Keeping up to date

Do keep up to date with exploits and vulnerabilities

  • Follow 0xDUDE on twitter.
  • Read the GDI.Foundation page.
  • Visit the Exploit Database
  • Vulnerability & Exploit Database
  • Subscribe to the Security Now podcast.

Secure your applications

  • NodeJS: Enable logging in applications you install or develop.

Ban repeat Login attempts with FailBan

Fail2Ban config

sudo nano /etc/fail2ban/jail.conf
[sshd]

enabled  = true
port     = ssh
filter   = sshd
logpath  = /var/log/auth.log
maxretry = 3

Hosts File Hardening

sudo nano /etc/host.conf

Add

order bind,hosts
nospoof on

Add a whitelist with your ip on /etc/fail2ban/jail.conf (see this)

[DEFAULT]
# "ignoreip" can be an IP address, a CIDR mask or a DNS host. Fail2ban will not                          
# ban a host which matches an address in this list. Several addresses can be                             
# defined using space separator.
                                                                         
ignoreip = 127.0.0.1 192.168.1.0/24 8.8.8.8

Restart the service

sudo service fail2ban restart
sudo service fail2ban status

Intrusion detection (logging) systems

Tripwire will not block or prevent intrusions but it will log and give you a heads up with risks and things of concern

Install Tripwire.

sudo apt-get install tiger tripwire

Running Tripwire

sudo tiger

This will scan your system for issues of note

Hardening PHP

Hardening PHP config (and backing the PHP config it up), first create an info.php file in your website root folder with this info

<?php
phpinfo()
?>

Now look for what PHP file is loadingPHP Config

Back that your PHP config file

TIP: Delete the file with phpinfo() in it as it is a security risk to leave it there.

TIP: Read the OWASP cheat sheet on using PHP securely here and securing php.ini here.

Some common security changes

file_uploads = On
expose_php = Off
error_reporting = E_ALL
display_errors          = Off
display_startup_errors  = Off
log_errors              = On
error_log = /php_errors.log
ignore_repeated_errors  = Off

Don’t forget to review logs, more config changes here.

Antivirus

Yes, it is a good idea to run antivirus in Ubuntu, here is a good list of antivirus software

I am installing ClamAV as it can be installed on the command line and is open source.

sudo apt-get install clamav

ClamAV help here.

Scan a folder

sudo clamscan --max-filesize=3999M --max-scansize=3999M --exclude-dir=/www/* -i -r /

Setup auto-update antivirus definitions

sudo dpkg-reconfigure clamav-freshclam

I set auto updates 24 times a day (every hour) via daemon updates.

tip: Download manual antivirus update definitions. If you only have a 512MB server your update may fail and you may want to stop fresh claim/php/nginx and mysql before you update to ensure the antivirus definitions update. You can move this to a con job and set this to update at set times over daemon to ensure updates happen.

sudo /etc/init.d/clamav-freshclam stop

sudo service php7.0-fpm stop
sudo /etc/init.d/nginx stop
sudo /etc/init.d/mysql stop

sudo freshclam -v

Uninstalling Clam AV

You may need to uninstall Clamav if you don’t have a lot of memory or find updates are too big.

sudo apt-get remove --auto-remove clamav
sudo apt-get purge --auto-remove clamav

Setup Unattended Ubuntu Security updates

sudo apt-get install unattended-upgrades
sudo unattended-upgrades -d

At login, you should receive

How to get useful feedback for your ideas

July 16, 2017 by Simon

I have witnessed investors are great at listening to pitches for the next best thing in order to snap up an investment offer. IMHO: Investors are worried about two things:

  • A) will this make money (with little effort from me)?
  • B) will this increase my success stats?

Feedback from Legal

Depending on your app idea you may need to get feedback from a legal expert.  It as always a good idea to not start building an app until you have validated your idea with potential paying customers, it is also a good idea to seek legal advice too. Only obtaining advice from a startup investor or agent may not be a good idea, ensure that your legal representative knows what they are talking about and has experience.

Feedback from Investors

Investors are very experienced but won’t necessarily give feedback like the Dragons Den or Shark Tank.

Feedback from Customers

Feedback from customers can also be dangerous as Trades Cloud found out.

Feedback from a Startup Mentor (board members) 

Me experience with mentors is they are like investors but only give advice in what they know. In my case feedback was all negative, they did not want to see what I had done, they advised don’t chase small profits (goes against: “small profit, large turnover”) and you should stop what you are doing, and chase after large profit. Also, I was advised to think about capital cities and not regions.

If you are only after money I would suggest you talk to an investor or startup mentor.

Project Types

Before you ask for or listen to feedback, are you developing a small product or a product and a startup, as the feedback you will receive will be quite different?  A smaller product may need feedback from customers but a start-up idea will need more thorough checks and idea validations.

I’d recommend you read this page on How To Start a Startup – Infographic if you want to create a startup.

This info-graphics was created by Anna Vital (based on an essay from by Paul Graham).

Feedback for a smaller idea

As a developer, you may want to get external feedback on your work, ideas or project. All feedback is good, right? This is what I have learned (so far).

The best feedback you can get is before development starts by talking to potential customers and end-users during alpha and beta testing.

Positive Feedback

  • Feedback can give you a fresh perspective and make you think.
  • Feedback can save you money.
  • Feedback can be free.

Negative Feedback

  • Don’t be disheartened when you hear negative feedback. All advice is good advice and it is up to you to contextualise and prioritise the feedback into tasks or actions.
  • People will tell you this has already been done already (after a quick Google but on detailed inspection this may not be the case).
  • Negative feedback can seed doubts.

Do or Don’t

Google is used by many for finding medical advice and it can also be used for finding out if a product or services exist already. But Google may turn you away from doing something. GoogleWhacking is a game where you try and find one search result with only two keywords entered into Google.

I have skipped countless cloud providers but I chose one based on what was important to me (value, performance, and ease of use). Product ideas are similar, it’s all in the execution and iterations.

Remember there was a social media platform called GeoCities before MySpace, did that stop Facebook? Social media, products, and services will come and go (remember Kodak and Blockbuster).

If in doubt find a good mentor.

Idea Validation

Good feedback should hurt and should make you think. Here is a good list of 232 failed start-up post mortems (I listed my favourite ones here).

I like Backblaze post on getting your first 1,000 customers.

Validate your ideas with customers and prioritize paying customers to feedback over free feedback. Providing polls asking what the future features should be is a good idea once you have 100 customers or more.

Pitches

If you are developing an idea be prepared to pitch your idea as the project grows. Pitches will succeed if you tick the listener’s boxes and don’t be concerned if pitches end in silence.

Ignoring Negative advice

People who give negative feedback may not know all of the details and will certainly forget the giving feedback hours later so don’t take negative feedback to heart.

I’d certainly listen to advice when it comes to money though.

People usually give feedback on what they know so don’t be too concerned if feedback is not what you expect.

Investors

Investors hate products that exist or may partially exist so do your research and explain how your solution solves existing problems or is better.

Do competitor or product checks and validate those problems beforehand.

Research

You have not thought of everything, again here is a good list of 232 failed start-up post mortems (I listed my favourite ones here).

Ensure you are delivering what people want (and the solution does not exist already).

Monetization is not everything

It is a common joke that “Investors make money, idea owners pay tax (and wages)”.

Rob Stitch (comedian) commented on the radio recently about the awesome Clarke and Dawes comedy sketch about a public bath that was questioned for not making money, the comedic punchline was “bad news for footpaths.”

Some things are more important than the costs if the need is high enough. But don’t burn a heap of money on silly ideas, aim small and scale up and iterate in public, get your feet wet early and iterate in public.

That’s easy for me to say but I would rather create stuff in my free time instead of burning money and time on other hobbies.

Be wary of people who only want to be involved in big money projects, want slices of your idea or be paid advisors. What motivates you may not motivate them.

How to get the feedback you need

Avoid people that do not listen and go into Yoda/advice mode before getting all the facts (especially if they were paid for giving advice).

How to use feedback you receive

Do prioritise advice from potential customers over all others. Atlassian blog gives tips using Jira to input feedback from customers in an agile project.

Park all feedback into a project task tracking software package like Trello or Jira (see my guide here). Ensure advice (and solutions) align with the initial problems and value. Additional advice may assist in obtaining VC capital or entering the startup building cycle but not help your initial customers problems. Feedback about higher monetization strategies may sound good to an Investor but would not help smaller customers with planned ideas.

Additional advice may assist in obtaining VC capital or entering the startup investor attracting cycle but not help your initial customers problems. Feedback about bigger monetization plans may sound good to an Investor but would not help existing customers with planned ideas.

Talk to the right people 

  • Talk to an investor if you need cash.
  • Talk to an end-user if you need feedback related to your product.
  • Talk to a developer if you need developer-related advice.

You will receive feedback about the things that people know.
