What are the two architectural approaches to defense in depth?
Defense in depth architecture Technical controls— include specialized software and hardware that are used to protect system resources. For example, antivirus or firewall solutions. Physical controls— include physical infrastructure for protecting systems, such as locked doors and security cameras.
What is the benefit of defense in depth model?
Defense-in-depth is an information assurance strategy that provides multiple, redundant defensive measures in case a security control fails or a vulnerability is exploited.
What is defense in depth architecture?
Defense in Depth (DiD) refers to an information security approach in which a series of security mechanisms and controls are thoughtfully layered throughout a computer network to protect the confidentiality, integrity, and availability of the network and the data within.
What is the basic principle of defense-in-depth?
Defense in depth is a straightforward principle: imagine your application is the last component standing and every defensive mechanism protecting you has been destroyed. Now you must protect yourself. For example, if you expect a firewall to protect you, build the system as though the firewall has been compromised.
What is an example of DiD defense-in-depth?
One example of effective defense-in-depth layers would include these types of security tools and solutions: Firewalls are software or hardware appliances that control network traffic through access or deny policies or rules. These rules may include black or whitelisting IP addresses, MAC addresses, and ports.
What are the layers of defense-in-depth?
Defense in depth can be divided into three areas: Physical, Technical, and Administrative.
- Physical controls.
- Technical controls.
- Administrative controls.
- Example.

Which is the best description of Defense in depth?
A well-structured defense architecture treats security of the network like an onion. When you peel away the outermost layer, many remain underneath it. No concept carries more importance when discussing network security than defense in depth.
Why is defense in depth important in network security?
No concept carries more importance when discussing network security than defense in depth. Defense in depth helps you protect network resources even if one of the security layers is compromised. After all, no single security component can be guaranteed to withstand every attack it might need to face.
What is the difference between defense in depth and layered security?
Defense in depth, on the other hand, assumes a broader range of possibilities, such as physical theft followed by forensic recovery of data by unauthorized persons, incidental threats as a result of dangers that do not specifically target the protected systems, and even perhaps such exotic threats as van Eck phreaking.
How are two security guards better than one?
Two security guards provide even more protection. But if both security guards get shot by masked bandits, then at least there’s still a wall of bulletproof glass and electronically locked doors to protect the tellers from the robbers.
