Free ISA Threat Analysis & Incident Response Questions and Answers

Question 1

What is the first step in the incident response process?

Accepted Answer

Preparation

Answer

The first step in the incident response process is preparation. This phase involves establishing policies, procedures, and teams, conducting training, and implementing necessary tools and technologies *before* an incident occurs. Effective preparation is crucial for an efficient and successful response when an actual security incident takes place, minimizing potential damage and recovery time.

Question 2

Which tool is commonly used to analyze network traffic for threats?

Accepted Answer

Wireshark

Answer

Wireshark is a powerful and widely used open-source network protocol analyzer. It allows security analysts to capture and interactively browse the data flowing on a network, making it an essential tool for troubleshooting network problems, analyzing network traffic, and detecting potential security threats or anomalies. Its deep packet inspection capabilities are invaluable for forensic analysis.

Question 3

What does IOC (Indicators of Compromise) refer to?

Accepted Answer

Evidence of a potential security breach

Answer

Indicators of Compromise (IOCs) are forensic artifacts found on a network or operating system that indicate a high probability of a computer intrusion. These can include unusual network traffic, malicious file hashes, suspicious registry keys, or unusual login patterns. Identifying IOCs is crucial for early detection and response to security breaches, allowing organizations to proactively defend against threats.

Question 4

Which phase of incident response involves isolating affected systems?

Accepted Answer

Containment

Answer

Containment is a critical phase in incident response that involves isolating affected systems or networks to prevent the incident from spreading further and causing more damage. This step aims to limit the scope and impact of the breach, allowing the incident response team to then focus on eradication and recovery. Effective containment minimizes the overall harm to the organization.

Question 5

What is the purpose of a SIEM system in threat analysis?

Accepted Answer

To provide real-time analysis of security alerts

Answer

A Security Information and Event Management (SIEM) system collects and aggregates log data and security events from various sources across an organization's IT infrastructure. Its primary purpose is to provide real-time analysis of these security alerts, enabling rapid detection of potential threats, compliance reporting, and incident response. SIEMs are essential for comprehensive threat analysis and proactive security monitoring.
