 <h3><a href="/security/">Security Center?</a></h3>
 <p>In an effort to make security related information more readily available, the PHP Security Response Team created a new Security Center on March 1st, 2007. The Security Center will serve as the central location where interested parties can find information about security threats, fixes and/or workarounds and any other related meterial.</p>
