Major improvements propositions

I read more and more mail about the fact the development of the antispyd project has stop for more than six months. However I always think about improvement for the project and I now imagine new features that has NEVER been developed in commercial solutions of corporation malware and inappropriate web use filtering.

In fact, I start to build this software when I was in an engineer school, now I am a PhD candidate in machine learning and I think can develop some really cool features :... read more

antispyd-0.0.9 released

This release provides a major improvement of the signature based filtering engine ( the BLOCK_SIGN filter), term of performance and functionnality.

The signatures are now stored in a 3-Tree to enhance the matching of each HTTP message.

Morevorer, this filtering can now be performed on each HTTP message content.

Finally, a signature can now use hexadecimal array of byte to specify a field's value.

For more informations ans samples,
See the man page :)... read more

Objectives for antispyd-0.0.9

I'm going to clean up and enhance the signature based threat detection engine (BLOCK_SIGN).
The main goals are :

- Speed up the signature checking :

The signatures will be stored in a 3-Tree to drastically reduce the number of test for each HTTP message.

- Enhance the signature definition:

A signature will be composed of 3 definition parameters : "url", "fld", "content" and an optional parameter "shape", to allow admins to specify what action to perform when a signature is matched.
Moreover, It will be possible to specify hexadecimal characters in the 3 definition fields of a signature.... read more

antispyd-0.0.8 released

This release provide two aspects :

- the capability of inter-connection with others HTTP cache and proxy, via a new configuration directive : "cache_peer" (I know you know it :) ) and "direct_connect" directive for fault tolerance.

- An HTTP engine acceleration via the use of the N-Tree algorithm for HTTP header fast reconnaissance.

Objectives for antispyd-0.1 : Stability and Effectiveness

The main goal of this release will be to provide a stable software package.

So, I will now work on some part of the code to increased usuability of the project like the configuration system and log system, to provide a more comprehensive error checking and log monitoring.

Moreover, I have already speed up the HTTP parsing system with the use of "Valued N-Tree" for the header type reconnaissance problem. Some other improvements have to, and will be, done.... read more

This control is performed with two independant technics : "HTTP header checking" and "HTTP flow tracking". ... read more

antispyd-0.0.5 released

The algorithm of url matching via N-Tree walking has been implemented and increases in a drastic way the efficient of the url filter :)

For the URL matching filter, it's now possible to use list file of url to match, as provide urlblacklist.com.
See the man for more details.

The server use now a pre-forked listen process architecture (R.I.P Steven). This design increase the global efficience too. A configuration directive has been added to specify the number of process to pre-fork.
See the man for more details too.... read more

It will be used for URL Matching and a future features of Domain matching (FILTER_DOMAIN will be implemented very soon).
