The presentation will be about the PHPIDS and how this system might be capable solving several security dilemmas of developers and site owners. Such as:
- Complexity of the webapp security topic vs. time pressure
- Diversity of attack patterns and techniques
- Costs for nowadays security solutions
- Obfuscated exploits vs. Blacklisting
- Techniques to detect attacks based on algorithms
- Massive usage of regular expressions vs. performance
The talk is potentially interesting for either security professionals, developers and project managers since the meaning and whereabouts of the PHPIDS will be introduced - as well as some regular expression black magic the system uses.
An important part of the presentation will be about possibilities to detect attacks without blacklists or other dictionary based techniques but by the plain buildup of the string.
The presentation is based on a white-paper about the PHPIDS - which can be found here
