Some things a HIDS will looks at Logins System Log files / audit files Application Log Files / audit files File Activity / Changes to software Configuration Files changes Processes being launched or stopped Use of certain programs CPU usage Network Traffic to/from Computer Advantages of HIDS (304) Can be operating system and application specific – might understand the latest attack against a certain service on a host (example, web server) They can look at data after it’s been decrypted (network traffic is often encrypted) Disadvantages of HIDS (305) Only protect one machine (or must be loaded on every machine you want to protect) Use local system resources (CPU/memory) They don’t see what’s going on, on other machines. Scalability The HIDS could be disabled if machine is hacked .
