Firewalls can be placed anywhere on the network, but are most commonly placed between these components: console and application server. Application servers and agents. Agent Manager and IBM Security Host Protection Agent.

What is the difference between Layer 2 and Layer 3 security?

Layer 2 switches work only with MAC addresses and do not interact with higher layer addresses such as IP. Layer 3 switches, on the other hand, can also perform static and dynamic routing, including IP and virtual local area network (VLAN) communications.

What is the most important security layer and why?

While endpoint security is a key component of a strong defense-defense posture, the network layer is the most important because it helps eliminate inbound vectors of servers, hosts, and other assets. .
