Segnalo l’articolo "The hole trick - How Skype & Co. get round firewalls"  di Jürgen Schmidt che illustra alcune delle tecniche usate da Skype per avere connettivita` in "reti difficili".

Sono rimasto abbastanza stupito quando leggendo questa notizia ho appreso di questo cambiamento di rotta, il nuovo IOS-XE sara` sviluppato prendendo come base un kernel linux e il suo target saranno i router di fascia alta come il ASR1000 che con il supporto per KVM (virtualizzazione in hardware) offrira` funzionalita` di ridondanza del sistema operativo.

Immagino quindi che gli sviluppatori Cisco si prefiggano di far girare due istanze di IOS che vengono tenute sincronizzate, in modo che nel caso muoia o vada in crash un’istanza ci sia l’altra ad entrare in azione finche` la prima non viene riavviata. Ma a dirsi sembra facile..

Era ora Cisco!

The IDS neither strips, sanitizes nor filters any malicious input, it simply recognizes when an attacker tries to break your site and reacts in exactly the way you want it to. Based on a set of approved and heavily tested filter rules any attack is given a numerical impact rating which makes it easy to decide what kind of action should follow the hacking attempt. This could range from simple logging to sending out an emergency mail to the development team, displaying a warning message for the attacker or even ending the user’s session.

PHPIDS enables you to see who’s attacking your site and how and all without the tedious trawling of logfiles or searching hacker forums for your domain. Last but not least it’s licensed under the LGPL!

Website: http://php-ids.org/
Demo: http://php-ids.org/demo/

I am using it from a lot of time and is a good score based IDS for web application developers.
