  • BFirewall
  • CAntivirus software
  • DIntrusion detection

Explanation

The components of Defense in depth include antivirus software, firewalls, anti-spyware programs, hierarchical passwords, intrusion detection, and biometric verification. In addition to electronic countermeasures, physical protection of business sites along with comprehensive and ongoing personnel training enhances the security of vital data against compromise, theft, or destruction. Answer: A is incorrect. A backdoor is any program that allows a hacker to connect to a computer without going through the normal authentication process. The main advantage of this type of attack is that the network traffic moves from inside a network to the hacker's computer. The traffic moving from inside a network to the outside world is typically the least restrictive, as companies are more concerned about what comes into a network, rather than what leaves it. It, therefore, becomes hard to detect backdoors.
