[OWASP-TESTING] Session Management Chapter for Part 2

Here you go...

1) Figure out what cookie, url parameter, or hidden field the site is using
to maintain a session
2) Search the code for that name
3) Trace all uses of that back through any variables, methods, etc...
4) If you find any -- write it up and strongly recommend that they use the
one provided by their webserver or application server -- like JSESSIONID

If they come up with a good reason why they have to roll their own (and none
are coming to my mind real quickly), then you gotta check the code to be
sure that the sessionid is cryptographically random and long enough not to
be guessable, only used over SSL, times out, destroyed on logout, etc...

Glyn, Any chance we can use the Chapter you wrote on Session Management
Testing as an appendix to Testing Part 1 to show readers what to expect
in Part 2 ?

Anyone volunteer to write a chapter a section on using Code Review to
test session Management that will compliment Glyns Chapter (which was
pen testing focused) ?
