SPLK-5001 Exam Dumps : Splunk Certified Cybersecurity Defense Analyst

The correct order of the examples listed corresponds toTactic, Technique, Procedurein the TTP framework:

Tactic:The high-level goal or objective an adversary tries to accomplish. "Extend movement" (likely meant as "Lateral movement") or "Exploiting a remote service" are tactics that describewhatthe adversary wants to do.

Technique:The general method or approach used to achieve the tactic. "Exploiting a remote service" is a technique, detailing the type of action used in pursuit of the tactic.

Procedure:The specific implementation or instance of a technique. "Use EternalBlue to exploit a remote SMB server" is a concrete procedure, an exact exploit tool or method used.

This hierarchy is fundamental to frameworks likeMITRE ATT&CK, which guides how analysts categorize and investigate adversary behaviors.

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 event disposition 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.

Adaptive Response is a feature in Splunk's Enterprise Security (ES) framework that allows security teams to automate actions and responses based on alerts or notable events. This feature is pivotal for orchestrating automated incident response processes, reducing the time between detection and response, and integrating Splunk with external systems to trigger appropriate actions.

Purpose:Adaptive Response enables the automation of specific tasks or workflows based on security events detected by Splunk ES. For instance, it can trigger actions such as isolating a compromised host, blocking IP addresses, or enriching data by querying additional sources when a notable event occurs.

Mechanism:When a notable event is identified within the Splunk platform, Adaptive Response can execute a series of predefined actions. These actions can be configured within the Splunk interface, allowing them to run automatically or with manual approval depending on the organization's needs. This capability is essential for streamlining security operations, especially in environments where quick response is critical.

Integration with External Applications:One of the key features of Adaptive Response is its ability to integrate with third-party security tools and solutions. This integration extends the capabilities of Splunk by allowing it to interact with other systems likefirewalls, intrusion prevention systems (IPS), endpoint detection and response (EDR) tools, and ticketing systems. This ensures a coordinated and comprehensive defense mechanism.

Usage in Security Operations:Security analysts often rely on Adaptive Response for managing and automating common security tasks, such as:

Quarantine or isolate a hostin response to malware detection.

Trigger a full disk scanwhen suspicious activity is detected.

Notify relevant stakeholdersthrough ticketing systems or direct communication tools.

Update firewall rulesto block traffic from a suspicious IP address.
