Till,
Here are some factors that you will want to ensure.
-Session token is delivered after authentication
-Each session token is unique and not predictable (requiring a strong
random token generator)
-Session token is transfer over an encrypted tunnel
-Session token is marked secure
-Ensure the session is terminated at logout
-Ensure the session times out in a reasonable amount of time
-All access control should be based on the user's session token and only
the session token
Optional
Don't allow concurrent sessions.
Don't allow IP hopping. (Changing of IP address mid session.)
There are more details that I am sure that someone one the list will
help fill in for you. But I believe these are a good start.

Subject: Session security with cookies
Hi, i'm investigating in web application security this time and i'm
trying to find some information about session management with cookies
and related security issues. Can anyone point me to tips on how to
make cookie based sessions more secure and how to prevent session
hijacking? How secure is session handling using cookies and what are
the main risks? Is anyone aware of good literature on that topic?
Thanks and have a nice day
Till
