Question 3

What is the difference between a vulnerability, a threat, and a risk?
Answer:
A vulnerability is a weakness in a system that can be exploited, like an unpatched software. A threat is a potential danger that could exploit that vulnerability, such as a malicious hacker. A risk is the potential for loss or damage when a threat exploits a vulnerability, considering both likelihood and impact.

Question 4

Describe the steps you would take during an incident response.
Answer:
First, I would prepare by having a plan and tools ready. Then, I’d identify the incident, confirming it’s real and understanding its scope. Containment follows, limiting damage and preventing spread. Eradication means removing the cause, then recovery restores systems. Finally, I would conduct a post-incident analysis to learn and improve.

Question 5

How do you stay updated with the latest security threats and technologies?
Answer:
I regularly follow industry blogs, subscribe to security newsletters, and participate in online forums. I also attend webinars and conferences whenever possible, and I dedicate time to hands-on learning with new tools. Continuous education is essential in this field, and I make it a priority.

Question 6

Explain the principle of least privilege.
Answer:
The principle of least privilege dictates that users, programs, or processes should only be granted the minimum necessary access to perform their functions. This reduces the attack surface and limits the potential damage if an account is compromised. It’s a fundamental security concept for minimizing risk.

Question 7

What is a SIEM system, and how have you used one?
Answer:
A SIEM (Security Information and Event Management) system aggregates and analyzes security alerts and log data from various sources across an organization. I have used SIEM platforms like Splunk or ELK Stack to monitor for suspicious activity, correlate events, and aid in incident detection and response by providing centralized visibility.

Question 8

What are some common types of cyber attacks you are familiar with?
Answer:
I am familiar with various attacks, including phishing, malware (like ransomware and viruses), Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) attacks. I also understand SQL injection, cross-site scripting (XSS), and man-in-the-middle attacks, which target web applications and network communications.

Question 9

How do you approach a penetration test report?
Answer:
When reviewing a pen test report, I first prioritize findings based on severity and potential impact. I then collaborate with relevant teams to understand the technical details of each vulnerability. My goal is to work towards remediation plans, track progress, and ensure that identified weaknesses are addressed promptly.

Question 10

What is encryption, and why is it important in information security?
Answer:
Encryption is the process of converting information into a code to prevent unauthorized access. It’s crucial for protecting sensitive data, both in transit and at rest, ensuring confidentiality and integrity. Without strong encryption, data could easily be intercepted and read by malicious actors, leading to breaches.

Question 11

Describe a time you identified a security vulnerability and what you did about it.
Answer:
During a routine system audit, I identified an outdated SSL/TLS configuration on a public-facing server. This exposed the system to known vulnerabilities.
