Describe the root access method of attacking a firewall.
What will be an ideal response?
This method is used when hackers want to return to a network and manipulate its data by using root or administrative access. A hacker attempts to gain this access by either using a back door to sniff the passwords or by using some other programming code to hijack a session and take control of the administrative sessions. The hacker has either already penetrated the firewall or is using a back door for root access. The hacker installs a rootkit that is used for a variety of purposes, such as password sniffing or injecting Trojans into the network after penetrating the root.
