SPLK-5001 Exam Dumps : Splunk Certified Cybersecurity Defense Analyst

The Lockheed Martin Cyber Kill Chain® is a widely recognized framework that breaks down the stages of a cyber attack. The stages are: Reconnaissance, Weaponization, Delivery, Exploitation, Installation, Command and Control (C2), and Actions on Objectives. The scenario described—modifying the registry on a compromised Windows system to ensure malware runs at boot time—fits into theInstallationphase. This phase involves placing a persistent backdoor or other malicious software on the victim's system, ensuring it can be executed again, even after a system reboot. By modifying the registry, the attacker is achieving persistence, a classic example of the Installation phase.

TheIdentity Centerdashboard in Splunk Enterprise Security is the primary interface for managing and reporting on user identities, including users currently on watchlists. This dashboard allows analysts to track user behavior, alerts, and notable events related to specific user identities, with the ability to view and manage watchlist membership.

Identity Centerprovides focused visibility into user-centric data and investigations.

Access Trackeris more general for access logs and authentication events but does not provide watchlist management.

Access CenterandIdentity Trackerare not standard dashboard names in Splunk ES.

TheSplunk Enterprise Security User Guiderecommends the Identity Center for watchlist monitoring and user-focused investigations.

Pyramid of Pain Overview:The Pyramid of Pain categorizes indicators based on how difficult they are for attackers to alter:

Hash Values (Low Impact):Attackers can easily change a file's hash by altering even a single byte, rendering this indicator obsolete.

IP Addresses, Domain Names (Moderate Impact):Slightly harder to change than hash values but still relatively easy for attackers to adapt.

TTPs (High Impact):Tactics, Techniques, and Procedures are the most difficult for attackers to alter because they involve the fundamental ways attackers operate. Detecting and responding to TTPs can significantly disrupt an attacker’s strategy.

Why Hash Values Are Least Effective:

Ease of Evasion:Attackers can quickly generate new hash values by modifying files, making it a weak indicator for continuous monitoring.

Short Lifespan:Once detected and blocked, a hash value is of limited use because attackers can simply recompile or pack the malware to create a new hash.
