Answer:
Defense in Depth (DiD).
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
Defense in Depth (DiD) can be defined as a concept or framework in cyber security that typically involves the process of layering multiple defensive mechanisms and security control throughout an information technology (IT) system, so as to prevent data theft or an unauthorized access to user data.
Basically, this cyber security technique is designed such that when a layer of the defensive mechanism fails, another security layer step in to mitigate and prevent the attack. Thus, it causes redundancy when an attacker exploits a vulnerability in a system, a breach of security or when one of the security layers fail.
