Which of the following refers to the process of verifying the identity of a person, network host, or
system process?

A.
Auditing

B.
Authentication

C.
Hacking

D.
Packet filtering

Explanation:

Authentication is a process of verifying the identity of a person, network host, or system process.
The authentication process compares the provided credentials with the credentials stored in the
database of an authentication server.
Answer option C is incorrect. Hacking is a process by which a person acquires illegal access to a
computer or network through a security break or by implanting a virus on the computer or network.
Answer option D is incorrect. Packet filtering is a method that allows or restricts the flow of specific
types of packets to provide security. It analyzes the incoming and outgoing packets and lets them
pass or stops them at a network interface based on the source and destination addresses, ports, or
protocols. Packet filtering provides a way to define precisely which type of IP traffic is allowed to
cross the firewall of an intranet. IP packet filtering is important when users from private intranets
connect to public networks, such as the Internet.
Answer option A is incorrect. Auditing is used to track user accounts for file and object access, logon
attempts, system shutdown etc. This enhances the security of the network. Before enabling auditing,
the type of event to be audited should be specified in the Audit Policy in User Manager for Domains.
