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.

Answer:
Preemptive scheduling is the scheduling which a process given to the CPU can be suspended if a more suitable process comes between execution.
For example :- In SJF (Shortest Job First) a more smaller process comes between the execution the CPU will execute the new process and the process which was in the execution will be suspended for the time being.
Non-Preemptive scheduling cannot suspend the process in between if a process is in execution it will be fully executed then other process will get executed.
Strict Non preemptive scheduling are not suitable for computer centers because it cannot execute process with more priority if it comes between the execution.
