Briefly describe four major components for protecting internal information flow inside an organization

Question

What will be an ideal response?

Answer 1

Firewall, virtual private network, intrusion detection system, and honeynet and honeypot are four components. A firewall is a single point between two or more networks where all traffic must pass; the device authenticates, controls, and logs all traffic. A virtual private network is a network that uses the public Internet to carry information but remains private by using encryption to scramble the communications, authentication to ensure that information has not been tampered with, and access control to verify the identity of anyone using the network. Intrusion detection systems are a special category of software that monitor activity across a network or on a host computer, watch for suspicious activity, and take automated action based on what it sees. A honeynet is a network of honeypots, and honeypots act as decoys and are watched to study how network intrusions occur.
