Default Username and Password: Sometimes something as simple as resetting both the default username and password goes overlooked.If a firewall is not configured to block all outgoing traffic and relying on rules and Access Control Lists put in place to control what internet traffic is allowed to leave the network, then a rogue app or piece of malware could easily dial out of the internal network and form a path back in for an exploit.Ĭommon Configuration Pitfalls, Oversights and Risks! The next logical question to ask of the auditee is, “What safeguards are in place to stop unwanted or unauthorized traffic not only from coming in but leaving the organization as well?”
Stateful firewall determines what is allowed to come in based on what was allowed to exit. The life of a session (the amount of time the connection is allowed to stay open) can be determined a few different ways, by either specifying a Timeout in the Firewall, relying on Client Side Cookies which will remain for the duration of the browser session, or simply by the sessions being dropped from the table as it fills up. it checks against an ACL/Firewall rules) to verify if the incoming traffic should be allowed to continue or be blocked altogether. When traffic returns to respond to the request, the firewall checks its session table and if a match is found, the traffic is allowed to pass, otherwise the firewall performs extra checks (i.e.
