The most common type of endpoint security is a firewall. A firewall is a piece of hardware or software that blocks certain types of traffic from entering or leaving the network.
Another type of endpoint security is an intrusion detection system (IDS). An IDS monitors traffic for signs of an attack and then alerts the administrator. IDSes can be either host-based or network-based. Host-based IDSes are installed on individual computers, while network-based IDSes are installed on routers and switches.
The last type of endpoint security is antivirus software. Antivirus software scans files for malware and removes it if found. It also updates itself regularly to keep up with new threats.
