What is the purpose of dynamic content filtering?
This kind of filter would allow an attacker to sneak information past the filter by making the packet look like a reply which can be done by indicating "reply" in the packet header. Which topic are you interested in? I have a home lab setup, and I have some confusion with Routing part.
For example, assume that you wish to configure your firewall so that all users in your company are allowed out to the Internet, but only replies to users' data requests are let back in. The Routing Table. Stateful inspection, also known as dynamic packet filtering , is a firewall technology that monitors the state of active connections and uses this information to determine which network packets to allow through the firewall.
This practice prevents port scanning, a well-known hacking technique.

By recording session information such as IP address es and port numbers, a dynamic packet filter can implement a much tighter security posture than a static packet filter. Juan schrieb: Outgoing packets that request specific types of incoming packets are tracked and only those incoming packets constituting a proper response are allowed through the firewall.
This dramatically increases the security capabilities of the firewall. Is NaaS the answer to bolster network infrastructure security strategy? Please have a look at this link:.
