Top 10 Questions for Cyber Security Engineer Interview

1. Describe the CIA triad and how it applies to cybersecurity?

The CIA triad is a model that describes the three main goals of cybersecurity: confidentiality, integrity, and availability. Confidentiality refers to protecting data from unauthorized disclosure, integrity refers to protecting data from unauthorized modification, and availability refers to ensuring that data is accessible to authorized users when needed.

• Confidentiality: Ensuring that only authorized users can access and view sensitive information.
• Integrity: Maintaining the accuracy and consistency of data by preventing unauthorized changes or modifications.
• Availability: Ensuring that authorized users can access and use data and systems when they need them.

2. Explain the different types of security controls and how they are used to mitigate cyber threats.

Technical Controls

• Firewalls
• Intrusion Detection Systems
• Anti-Malware Software
• Encryption
• Two-Factor Authentication

Administrative Controls

• Security Policies
• Employee Training
• Incident Response Plans
• Risk Assessments

3. Discuss the role of security testing in identifying and addressing vulnerabilities.

• Vulnerability Scanning: Identifying potential weaknesses in systems and networks.
• Penetration Testing: Simulating real-world attacks to exploit vulnerabilities and assess defenses.
• Code Review: Inspecting code to find security flaws and vulnerabilities.
• Risk Assessment: Evaluating the potential impact of vulnerabilities and determining appropriate mitigation strategies.

4. Describe the incident response process and your role in it as a Cyber Security Engineer.

• Identification and Assessment: Detecting and analyzing security incidents.
• Containment and Mitigation: Preventing the incident from spreading and limiting its impact.
• Recovery: Restoring systems and data to normal operation.
• Lessons Learned and Communication: Documenting and sharing lessons learned to improve security posture.

5. Explain the concepts of risk assessment and risk management in cybersecurity.

Risk Assessment

• Identifying potential threats

• Uses: Securing data in transit, protecting sensitive information, verifying authenticity

8. Describe the different types of security logs and their importance in incident detection and investigation.

• System Logs: Recording events and activities within a system
• Application Logs: Recording events and activities within applications
• Network Logs: Recording network traffic and events
• Security Logs: Recording security-related events and incidents

9. Explain the concept of threat intelligence and its role in cybersecurity.

• Information about potential threats, vulnerabilities, and attack methods
• Used to improve security posture by identifying and mitigating risks
• Sources: Open-source intelligence, law enforcement, commercial vendors

10. Describe the ethical considerations and responsibilities of a Cyber Security Engineer.

• Protecting privacy
• Maintaining confidentiality
• Avoiding conflicts of interest
• Reporting security breaches
• Complying with regulations
