Splunk Updated SPLK-5001 Exam Questions and Answers by ibraheem

TheContinuous Monitoringcycle begins with theDefine and Predictphase, where the security team establishes what needs to be monitored (defining assets, risks, controls) and predicts potential threats and vulnerabilities. This foundational phase sets objectives and scope for the monitoring program.

Subsequent phases likeMonitor and Protect,Assess and Evaluate, andRespond and Recoverfollow the initial definition.

This phased approach aligns with frameworks such as NIST’s Risk Management Framework and Continuous Monitoring guidelines.

Splunk’s cybersecurity documentation highlights the importance of this first phase for establishing a proactive and informed security posture.

Data Model Acceleration (DMA)in Splunk is used to improve search performance by creating summarized, indexed versions of data models that enable much faster retrieval than querying raw indexed data directly. This acceleration is particularly beneficial for complex searches, dashboards, and reports based on large datasets.

DMA precomputes and stores data aggregates, allowing near real-time responses for repeated queries.

It does not normalize data—that function is handled by CIM and data models themselves.

DMA is unrelated to comparing algorithms or modeling response actions.

According toSplunk documentation, enabling acceleration on data models significantly reduces search latency and enhances user experience, especially in security operations with high volumes of data.

This scenario is an example of aFalse Negativebecause the detection mechanisms failed to generate alerts for a brute-force attack due to a misconfiguration—specifically, the exclusion of Linux data from the detection searches. A False Negative occurs when a security control fails to detect an actual malicious activity that it is supposed to catch, leading to undetected attacks and potential breaches.

Indicators of Compromise (IOCs) are artifacts that are used to identify potential malicious activity within a network or system. Common IOCs include domains, IP addresses, and file hashes that are associated with malicious activity. However, a specific password, while potentially sensitive, is not typically considered an IOC because it is more of a credential than an artifact indicating a compromise. IOCs are used to detect and respond to threats, while compromised credentials are a result of those threats.
