WWW Services

Apache HTTP Server

The Apache HTTP Server Project is an effort to develop and maintain an open-source HTTP server for modern operating systems including UNIX and Windows NT. The goal of this project is to provide a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards


http://www.apache.org
   
HTTP Service Support Modules
 
mod_php


mod_php embeds a persistent PHP interpreter in the Apache webserver. Thus overhead of starting an external interpreter and avoids the penalty Interpreter start-up time, thus accelerating PHP based dynamic content



http://www.php.net
mod_perl




as mod_php only it embeds the Perl Interpreter.



http://perl.apache.org
mod_python




as mod_php only it embeds the Python Interpreter



http://www.modpython.org
mod_ssl

provides strong cryptography for the Apache webserver via the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols by the help of the Open Source SSL/TLS toolkit OpenSSL. In a word its what make the https protocol possible in  the Apache webserver.


http://www.modssl.org
   
HTTP Service Support Libraries
 
mcrypt

Libmcrypt, which contains encryption functions, and provides a standardized mechanism for accessing them. Use by PHP

Snort is an open source network intrusion prevention system, capable of performing real-time traffic analysis and packet logging on IP networks. It can perform protocol analysis, content searching/matching and can be used to detect a variety of attacks and probes, such as buffer overflows, stealth port scans, CGI attacks, SMB probes, OS fingerprinting attempts, and much more. Over the years Snort has evolved into a mature, feature rich technology that has become the de facto standard in intrusion detection and prevention.
