Incident Response & Remediation Flashcards

What is the first step in an incident response process?

Answer: Identify the incident

The first crucial step in any incident response process is identification, which involves detecting and confirming that a security incident has occurred. This includes monitoring systems for anomalies, analyzing alerts, and determining the scope and nature of the potential breach. Without proper identification, no further effective response actions can be taken.

Which tool is commonly used in Microsoft security operations for investigating security incidents?

Answer: Microsoft Sentinel

Microsoft Sentinel is a powerful SIEM (Security Information and Event Management) solution that centralizes security data from various sources, making it an ideal tool for investigating security incidents. It provides advanced analytics, threat intelligence, and automation capabilities to help security operations analysts efficiently detect, investigate, and respond to threats within Microsoft environments. Its comprehensive features are tailored for incident investigation.

What is the primary goal of incident containment?

Answer: Prevent further damage and isolate systems

The primary goal of incident containment is to limit the scope and impact of a security incident by preventing it from spreading further within the network or causing additional damage. This often involves isolating affected systems, disconnecting compromised devices, or implementing temporary network segmentation to stop the attack's progression and minimize harm.

What is the purpose of a post-incident review?

Answer: Analyze and improve security measures

A post-incident review, also known as a lessons learned session, is conducted after an incident has been resolved to analyze what happened, how it was handled, and what could be improved. Its purpose is to identify weaknesses in security controls, refine incident response procedures, and implement changes to prevent similar incidents in the future, thereby continuously improving security measures.

Which of the following is a key strategy in incident remediation?

Answer: Applying security patches and updates

Incident remediation focuses on eliminating the root cause of the incident and restoring affected systems to a secure state. A key strategy involves applying security patches and updates to fix vulnerabilities that were exploited, ensuring that systems are hardened against future attacks and preventing re-infection. This step is crucial for long-term security and system integrity.

What is a major benefit of automated incident response?

Answer: Reduces response time and increases efficiency

Automated incident response leverages technology to perform repetitive or time-sensitive tasks, such as blocking malicious IPs or isolating compromised hosts, without human intervention. This significantly reduces the time it takes to detect and respond to incidents, thereby increasing the overall efficiency of security operations and minimizing potential damage from cyber threats.
