Interviewer: How do you approach risk management in your work?
Candidate: I believe in a risk-based approach to security that prioritizes the most critical assets and the most significant threats. I work to identify and evaluate risks, and then implement measures that balance the need for security with the organization’s goals and resources.
Interviewer: How would you handle a non-compliant employee who refused to follow security policies and guidelines?
Candidate: I would first seek to understand the reasons for the non-compliance and work to address any concerns or confusion. If necessary, I would escalate the issue to relevant stakeholders and management to ensure compliance and mitigate any potential risks.
Interviewer: Can you tell us about your experience with incident response and disaster recovery?
Candidate: I have experience responding to various security incidents, including data breaches, DDoS attacks, and ransomware infections. I have also participated in creating and testing disaster recovery plans to ensure continuity of operations in case of a catastrophic incident.
Interviewer: How do you approach vendor management and the security of third-party software and systems?
Candidate: I believe in a risk-based approach to vendor management that includes evaluating the security of third-party software and systems. I work to ensure that vendors have appropriate data security measures in place and adhere to our security policies and guidelines.

Interviewer: How would you handle a security incident that occurred outside of business hours?
Candidate: I would follow the incident response plan that we have in place, which includes contacting the relevant team members and stakeholders, assessing the severity of the incident, and containing the threat. I am also available for on-call duties to respond to security incidents outside of regular business hours.
Interviewer: Can you describe your experience with access control systems, including identity and access management solutions?
Candidate: I have experience working with various identity and access management solutions, such as Okta and Active Directory. I am skilled in creating and implementing access control policies and evaluating their effectiveness.
Interviewer: Can you tell us about your experience with regulatory compliance frameworks, such as PCI DSS or HIPAA?
Candidate: I have worked with various regulatory compliance frameworks and understand their unique requirements and challenges. I have experience conducting audits and assessments to ensure compliance and working with stakeholders to implement appropriate security measures.
1. Scenario: A company receives an email from what appears to be a reputable source asking for sensitive information such as passwords and social security numbers. What steps would you take to address this potential phishing attack?
Candidate Answer: The first thing I would do is validate the source of the email to determine if it is legitimate or not. I would check the email address to see if it matches the known email of the legitimate source. If I am not sure, I would reach out to the potential sender through a different method, like a phone call or a separate email chain, to confirm whether they sent the email or not. Under no circumstances would I provide the sensitive information requested, and I would report the suspicious email to my supervisor and the IT security team.
2. Scenario: A large retail chain has experienced a security breach that has compromised customer data. What steps would you take as an Information Security Analyst to manage the incident and prevent further compromise?
Candidate Answer: As soon as I become aware of the breach, I would immediately isolate the affected systems to prevent further data loss. Then, I would conduct a thorough investigation to identify the scope and location of the breach, including what type of information was accessed, how it happened, and how long it has been going on. Once I have a clear understanding, I would notify the customers affected and work with the IT team to remediate the vulnerability, and provide any additional training needed to prevent future incidents.
3. Scenario: A business partner is requesting access to classified company information, but their security protocols do not meet your company's standards. How would you address this situation as an Information Security Analyst?
Candidate Answer: I would first notify my supervisor and the legal team to seek guidance on how to proceed. If it is determined that the business partner still requires access to the information, I would work with them to identify the specific security deficiencies and develop a plan to address them. However, under no circumstances would I grant access until these security requirements are met, as it could significantly impact the security of our company's sensitive data.
4. Scenario: A company's website is experiencing a Distributed Denial of Service (DDoS) attack, causing the site to go down. What steps would you take to address this attack?
Candidate Answer: The first thing I would do is activate the company's emergency incident response plan, which should outline specific steps to address a DDoS attack. I would work with the IT team to identify the source of the attack and assess its severity, and then implement mitigation measures, such as filtering the traffic to the website and increasing bandwidth to handle the higher traffic volume. I would also monitor the situation closely and continuously gather data to refine the response and prevent future attacks.
5. Scenario: A company employee has had their laptop stolen, and it contained sensitive company information. What steps would you take as an Information Security Analyst to minimize damage and prevent further loss?
Candidate Answer: First, I would ensure that the employee immediately reports the incident to their supervisor and the security team. Then, we would take action to remote wipe the stolen laptop and immediately change all passwords and access codes related to the employee's access. We would also conduct a detailed investigation into the incident and work with law enforcement if necessary. As a follow-up, we would take measures to train all employees on the proper handling and storage of sensitive company information.
