SPLK-5001 Exam Dumps

Explanation: 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.

Explanation: In incident response and cybersecurity operations, Mean Time to Respond (MTTR) is a key metric. It measures the average time it takes from when an alert is created to when it is resolved or closed. In the scenario, an analyst identifies a Risk Notable Event as a false positive and closes it; the time taken from the alert's creation to its closure is what MTTR measures. This metric is crucial in understanding how efficiently a security team responds to alerts and incidents, thus contributing to overall security posture improvement.

Explanation: In this scenario, the analyst cannot conclude whether the Notable Event is a true positive or a false positive due to the absence of necessary logs and artifacts. The appropriate eventdisposition in this case is "Other," as it indicates that further action is required, such as ingesting the missing logs. The involvement of a security engineer to ensure the necessary data is available for proper investigation is implied, making "Other" the most suitable option.

Explanation:
The log entry showing the same request repeated millions of times indicates aDenial of Service (DoS) Attack, where the server is overwhelmed by a flood of requests to a specific resource, in this case, the/login/page. This type of attack is aimed at making the server unavailable to legitimate users by exhausting its resources.

• Denial of Service Attack:
• Incorrect Options:
• Web Server Security: Understanding DoS attacks is critical for securing web servers and mitigating these types of disruptions.

Explanation: For creating a custom dashboard focused on typosquatting, theNew Domain Analysisdashboard in Splunk Enterprise Security (ES) would be a relevant starting point. Typosquatting typically involves the registration of domains similar to legitimate domains to deceive users, which is closely related to the analysis of newly registered or observed domains. This dashboard already includes tools and visualizations for monitoring and analyzing domain name activity, which can be adapted for the specific needs of monitoring for typosquatting.

Explanation: An executable running from theC:\Windows\Tempdirectory is a significant red flag because temporary directories are often world writable, meaning any user or process can write files to them. This characteristic makes these directories an attractive target for attackers who want to drop, stage, and execute malware without worrying about restrictive file permissions.
Temp Directories Characteristics:
Security Risks:
Investigation Importance: The fact that an executable is running fromC:\Windows\Tempwarrants further investigation to determine whether it is malicious. Analysts should check:
Windows Security Best Practices: Documentation on how to secure temp directories and monitor for suspicious activity is available from both Microsoft and various security communities.
Incident Response Playbooks: Many playbooks include steps for investigating suspicious activity in temp directories as part of broader malware detection and response strategies.
MITRE ATT&CK Framework: Techniques involving the use of temporary directories are well-documented in the framework, offering insights into how adversaries leverage these locations during an attack.
