SPLK-5001 Exam Dumps : Splunk Certified Cybersecurity Defense Analyst

The MITRE ATT&CK framework categorizes Tactics, Techniques, and Procedures (TTPs) used by attackers. It is a globally accessible knowledge base of adversarial tactics and techniques based on real-world observations, and it is widely used by cybersecurity professionals to understand and defend against various cyber threats.

Tactics, Techniques, and Procedures (TTPs):

Tactics:The high-level goals that attackers aim to achieve during an attack. For example, gaining initial access to a network.

Techniques:The specific methods used to achieve these tactics, such as phishing or exploiting a vulnerability.

Procedures:The detailed steps and tools that attackers use to implement a technique.

MITRE ATT&CK Framework:MITRE ATT&CK organizes these TTPs into a matrix that reflects different stages of an attack lifecycle, from initial access to exfiltration. The framework helps security teams by:

Mapping Detection and Defense:Organizations can map their existing detection capabilities against the ATT&CK matrix to identify gaps.

Threat Hunting:Security teams use the framework to guide their threat-hunting activities, focusing on specific techniques associated with known adversaries.

Incident Response:During incident response, analysts can use the ATT&CK framework to understand the behaviors exhibited by an attacker, which helps in creating effective containment and eradication strategies.

Why MITRE ATT&CK:Unlike compliance-focused frameworks like NIST 800-53 or ISO 27000, which provide security controls and best practices, MITRE ATT&CK is specifically focused on the behavior of adversaries. This focus makes it an invaluable resource for understanding how attacks unfold and how to counteract them.

In Splunk,default metadatarefers to automatically assigned attributes associated with each event at indexing time that help identify and organize data. These include:

Source: The origin of the data (file, network port, etc.)

Timestamps: The time the event occurred, extracted from the event or assigned at ingestion

Host name: The name of the host generating the event

Event descriptionis not a default metadata field in Splunk. It is typically user-defined or derived from the event content and is not assigned automatically by Splunk.

TheSplunk documentationon event metadata clarifies these standard fields, which are crucial for search filtering and data organization.

TheevalSPL expression in Splunk supports several categories of functions, includingJSON functions(e.g.,spath),Text functions(e.g.,substr,trim), andComparison and Conditional functions(e.g.,if,case). However,Threat functionsis not a valid category within theevalcommand. Theevalcommand is primarily used for transforming and manipulating data in various ways, but it does not include a category specifically for threat-related functions.
