=== IN FOCUS: How to Write Secure PHP Code ============   by Mark Joseph Edwards, News Editor, mark at ntsecurity / net

Last week, I wrote about a few things you need to know about securing 
your PHP installations. I also pointed to several sites that offer good 
information about what to look out for and what configuration changes 
you might need to make. If you missed that article, you can read it on 
our Web site at the URL below. 
http://list.windowsitpro.com/t?ctl=4DFC7:57B62BBB09A6927928FAD7D792CB2F3D 

If you have PHP installed, then obviously you're going to run PHP code. 
Some of that code might be written by third-party developers and some 
of it you might write yourself. Either way, you should learn about 
secure coding practices for PHP. Doing so can help you write better 
code and help you audit third-party code for potential problems. 

As an example of why the latter is important, be sure to read my blog 
article "Gaping Hole in Wordpress" (you can link to it from the GIVE 
AND TAKE section of this newsletter below) to learn about how someone 
slipped some "back doors" into Wordpress, which is a hugely popular 
PHP-based blogging platform. You can write simple scripts that audit 
third-party code to look for potential back doors by scanning the code 
for any or all of the dangerous functions I discussed last week. 

To help you write your own secure PHP code, I went looking for 
resources and found several decent Web sites that provide writing aid 
and some tools that look for coding vulnerabilities. The sites at the 
URLs below are a big help, so take some time to study them carefully. 
If you know of any others, send me a message with a URL and I'll share 
it here in the newsletter for everyone's benefit.

NAC Appliance Gets Cheaper and Faster
   Nevis Networks announced LANsecure OS 3.0 for its LANenforcer 
network access control (NAC) appliances. Highlights of the new OS 
version are faster endpoint posture checks coupled with identity-based 
access control, a three-fold increase in user capacity on LANenforcer 
appliances (resulting in reduced costs), and integration with existing 
identity-management systems to enforce predefined application access 
policies to simplify administration. Prices for LANenforcer appliances

19. For more information, go to
