Get 312-39 Dumps : Verified Certified SOC Analyst (CSA)

Once an L2 SOC Analyst like Charline confirms an incident, the SOC workflow dictates that the incident must be formally documented. This involves raising a ticket in the incident management system. The ticket should include all relevant details from the investigation, such as the nature of the incident, the affected systems, and the initial priority assigned. After raising the ticket, the L2 Analyst should forward it to the Incident Response Team (IRT). The IRT will then take over the incident to conduct a deeper analysis, perform containment measures, eradicate the threat, and recover systems to normal operation.

A Rainbow Table Attack involves using a precomputed table of hash values for every possible combination of characters for a given password policy. This table, known as a rainbow table, is then used to look up the corresponding plaintext password for a given hash value. The process involves the following steps:

• Precomputation: Generate the rainbow table by computing hash values for all possible password combinations according to the password policy.
• Storage: Store these precomputed hash values in a table, associating each with its plaintext password.
• Lookup: When a hash value is obtained during a password cracking attempt, search the rainbow table for the corresponding plaintext password.
• Match: If a match is found, the plaintext password associated with the hash value is the cracked password.

Rainbow tables are effective because they trade storage space for time, allowing for quicker password cracking compared to brute-force or dictionary attacks, which compute hash values on the fly.

References: The EC-Council’s materials on password cracking techniques discuss various methods including dictionary attacks, brute-force attacks, and rainbow table attacks. Specifically, the EC-Council Learning Paths and Skill Packs provide detailed insights into these techniques, emphasizing the use of rainbow tables as a method of cracking passwords by comparing precomputed hash values to those obtained from a system12. Additionally, EC-Council’s CyberQ platform offers practical exercises related to password cracking, including the use of rainbow tables2.

A DHCP Starvation Attack is a type of network attack that aims to deplete the pool of available IP addresses on the DHCP server. The attacker floods the DHCP server with fake DHCP DISCOVER messages using spoofed MAC addresses. If successful, the server will exhaust its address space, denying IP configuration to legitimate clients. This can lead to a denial of service (DoS) for new devices attempting to join the network. Additionally, the attacker may set up a rogue DHCP server to issue malicious IP configurations to clients, potentially redirecting traffic or causing further disruption1.

References: The EC-Council SOC Analyst course and study materials cover various network attacks, including DHCP Starvation Attacks. These resources provide insights into the nature of these attacks, their potential impact, and strategies for prevention and mitigation213.

The eradication stage is where the root cause of the incident is determined from the forensic results. This stage involves not only removing the threat from the affected systems but also identifying and fixing the vulnerabilities that were exploited. It’s crucial to understand how the incident occurred to prevent future occurrences. After the containment stage, where the immediate threat is isolated, eradication ensures that the threat is completely removed and that the root cause is addressed.

References: The EC-Council’s Certified Incident Handler (E|CIH) program outlines the stages of incident handling and response, which include preparation, identification, containment, eradication, recovery, and lessons learned. The eradication stage specifically deals with eliminating the threat and addressing the root cause based on forensic analysis. This information is covered in the E|CIH program and can be found in the official EC-Council learning resources1.

The Windows event that is logged when a user tries to access a “Registry” key is identified by the event ID 4657. This event ID corresponds to the modification of a registry value. Here’s how the process is tracked and logged:

• Detection: The system monitors access to registry keys and values.
• Logging: If a user accesses a registry key, and the key’s audit policy is set to log such events, the event is logged.
• Event ID 4657: This specific event ID is used to denote that a registry value was modified, which includes creation, modification, and deletion of registry values.
• Audit Policy: For the event to be logged, “Set Value” auditing must be enabled in the registry key’s System Access Control List (SACL).

References: The EC-Council SOC Analyst course materials and study guides detail the various Windows event IDs and their significance in monitoring and analyzing security events. Event ID 4657 is specifically covered as part of the curriculum that deals with registry access monitoring and logging1. Additionally, Microsoft’s official documentation provides comprehensive information on this event ID and its role in security auditing2.
