7. What is the concept of ‘defense in depth’?

Answer:
Defense in depth is a layered security approach where multiple security measures are used to protect information. If one layer is breached, other layers remain intact to provide continued protection.

Sample Answer:
"Defense in depth ensures that security is not reliant on a single control. It combines various techniques, such as firewalls, encryption, and access controls, to protect data at different levels."

8. What is the role of encryption in information security?

Answer:
Encryption is used to protect sensitive data by converting it into a code that can only be deciphered by authorized parties. It ensures that even if data is intercepted, it remains unreadable without the proper decryption key.

Sample Answer:
"Encryption is crucial for maintaining confidentiality, especially for sensitive data transmitted over networks or stored on devices. It ensures that unauthorized access to information is prevented, even if the data is intercepted."

9. How would you handle security breaches in a network?

Answer:
I would immediately follow the organization’s incident response plan to contain the breach, assess the damage, notify stakeholders, and work with relevant teams to remediate the issue. Post-incident, I would conduct a root cause analysis to ensure similar incidents don’t occur.

Sample Answer:
"First, I would contain the breach to prevent further damage, then identify and fix the cause. Afterward, I would analyze the incident to strengthen future security measures and report to senior management as needed."

10. What is the significance of business continuity planning (BCP) in security management?

Answer:
BCP ensures that critical business functions continue with minimal disruption, even in the event of a disaster or security incident. It integrates contingency strategies to keep operations running during and after incidents.

Sample Answer:
"Business continuity planning ensures that essential operations are maintained during disruptive events. It minimizes downtime and enables organizations to quickly recover, protecting both the organization’s assets and reputation."

11. What are the main types of security controls?

Answer:
Security controls can be preventive, detective, corrective, or compensatory. Each type plays a distinct role in safeguarding assets by preventing, detecting, correcting, or compensating for security failures.

Sample Answer:
"Preventive controls block threats before they can cause harm, detective controls identify breaches in real time, corrective controls fix issues after they occur, and compensatory controls provide alternative methods for protection when primary controls fail."

12. What is the role of compliance in information security management?

Answer:
Compliance ensures that the organization’s security policies, practices, and controls meet the legal, regulatory, and industry requirements. It helps avoid penalties, legal risks, and reputational damage.
