Web Application Security for Developers presentation

Last nights Guernsey Software Developers Forum meeting was sparsely attended with a number of the regulars attendees absent. There were however two new faces including Kezzer who I’d been chatting to on-line for years.

Hopefully the low numbers were down to the seasonal summer holidays and the subsequent knock-on effect that we couldn’t get email out to the BCS Guernsey division to gather sufficient awareness.

I did a short presentation on Web Application Security for Developers that covered HTML injection, SQL injection and cross-site scripting including some live demonstrations on sample code. Slides and sample are available although without audio or screen cast of the demonstrations until I work out how to do that with Keynote.


I’ve come to the conclusion that putting presentations together takes me around 1 hour of preparation to 1 minute of presentation…


Web Application Security presentation in Guernsey

This presentation is now available on-line.

I will be giving a talk about web application security tonight at the Guernsey Software Developers Forum.

Web application security is a very large subject I will only be covering SQL injection, HTML injection/cross-site scripting and input manipulation. If there is enough interest I’ll consider covering other subjects such as session hijacking, defensive programming, hashing etc. in a future talk.

As always the doors are open to everyone opening at 6pm tonight (Wednesday 15 August 2007) at the Guernsey Training Agency above the Post Office in Smith Street.

The talk will last around 30 minutes but the meetings tend to go on to around 7:30pm for those that want to discuss it or other developer topics.


Guernsey Software Developers Forum, June 28th


A number of changes are happening within the Guernsey Developer Users Group!

We have changed the name to the Guernsey Software Developers Forum to better reflect the nature of the events and moved the Guernsey Software Developers Forum web site over to a new location, host and software.

It is also our intention to arrange presentations as often as possible as fewer members were interested in the free-format discussion events.

Next event

The next event will be on Thursday 28th of June 2007 starting at 6pm at the Guernsey Training Agency offices above the post-office in Smith Street, St. Peter Port.

As always the doors are open to everyone so if you have an interest in any of these subjects just turn up and grab a chair. The planned agenda is:


Welcome to the forum, news and announcements.

Guernsey mobile plans

Now that Sure and Wave/JT are operating in both islands competition is heating up unless you want 3G in Guernsey because the government awarded the licence to somebody who doesn’t operate whilst refusing a licence to the biggest operator. Way to go.

Basic plans

Wave/JT should be commended for offering the same plan and rates across the islands.

Sure have some balancing to do between island and need to offer a lightweight plan below their basic £20 a month rental in Guernsey. They do offer cheaper rental pricing when taking out an 18 month contract however.

Both operators have a make-your-own-plan scheme available.
