Which of the following is a set of controls in order that satisfy the Defense-In-Depth?Group of answer choicesPolicies and Procedures, Virtual Private Network (VPN), Firewall, Access ControlLocked external gates, Security guard, Locked internal doors, Locked server roomFirewalls, Intrusion detection system, Anti-malware, Access controlAll of these

The concept of Defense-In-Depth is a layered defensive strategy that uses multiple security measures to protect information. This strategy is based on the military principle that it is more difficult for an enemy to defeat a complex and multi-layered defense system than to penetrate a single barrier.

1. Policies and Procedures, Virtual Private Network (VPN), Firewall, Access Control: These are

The concept of Defense-In-Depth is a strategy that employs a series of mechanisms to slow the advance of an attack aimed at acquiring unauthorized access to information. Each layer provides protection so that if one layer is breached, a subsequent layer is already in place to prevent further exposure.

Looking at the options:

1. Policies and Procedures, Virtual Private Network (VPN), Firewall, Access Control: These are all important components of a comprehensive security strategy. Policies and procedures establish the rules for network use, VPNs provide secure remote access, firewalls protect the network perimeter, and access controls limit who can access what.

2. Locked external gates, Security guard, Locked internal doors, Locked server room: These are physical security measures. While they are important, they are not the only components of a Defense-In-Depth strategy.

3. Firewalls, Intrusion detection system, Anti-malware, Access control: These are all technical controls that can be part of a Defense-In-Depth strategy. Firewalls protect the network perimeter, intrusion detection systems monitor for suspicious activity, anti-malware protects against malicious software, and access controls limit who can access what.

4. All of these: This option suggests that all of the above are part of a Defense-In-Depth strategy. While it's true that a comprehensive strategy would include elements of all of the above, not all of them are strictly necessary for every situation.

So, the answer to the question "Which of the following is a set of controls in order that satisfy the Defense-In-Depth?" would be "Firewalls, Intrusion detection system, Anti-malware, Access control". This is because these controls cover multiple layers of defense, from the network perimeter to the individual user, and include both preventive and detective measures.
