Web Perl CGI & PHP Security Issues
Tuesday, June 16th, 2009Security on the web takes a backseat to functionality and aesthetics. Guidelines to security can be few and far between. These are just some of the most common security issues to be aware of when programming web applications using the CGI environment, Perl and PHP.
The CGI environment is the Common Gateway Interface used by Perl for access to an application on the web server through the user agent. Perl is a server-side programming language that uses an interpreter that compiles the script and executes it on the web server. PHP is the server-side preprocessing hypertext language that is embedded in SGML documents and parsed upon the user agent’s request for the document, then executed with the results displayed to the web application user.
This briefing includes sections on Programming Security & Web Security Resources. The next briefing will be on counter measures to combat threats to web application security.
