To maximize the effectiveness of a threat hunting program, organizations should adhere to several best practices related to methodologies, tools, team composition, and the integration of threat intelligence:
Three popular threat hunting methodologies include the hypothesis-driven approach, the review of attack indicators, and the use of ML- and AI-based tools.
Adopt Diverse Threat Hunting Methodologies
Hypothesis-driven
This includes spotting abnormalities, formulating an educated guess about what caused them, and reviewing data to validate whether potential threats should be investigated.
Review of attack indicators
Threat intelligence platforms are used to find indicators of compromise or attack that should then be researched further.
ML- and AI-based assessments
With machine learning and artificial intelligence, data is automatically reviewed and abnormal behaviors can be identified.
Threat hunting tools complement existing endpoint detection and response (EDR) tools by offering more complex and detailed analysis to discover suspicious behaviors and patterns that EDR tools cannot detect.
Utilize Specialized Threat Hunting Tools
Threat hunting tools go beyond traditional endpoint detection and response (EDR) solutions by providing deeper analysis of suspicious behaviors and patterns that automated tools might miss. These tools help hunters detect advanced threats that evade conventional defenses.
Build a Dedicated Threat Hunting Team
A specialized team focused solely on threat hunting is essential. These teams require a unique skill set, including expertise in using advanced tools, understanding the latest threat landscapes, and creatively thinking about potential attack vectors. Dedicated threat hunters can operate with a proactive mindset, continuously searching for threats rather than waiting for alerts.
Leverage Threat Intelligence:
Threat intelligence is crucial for informing and guiding threat hunting efforts. It provides context on the severity of threats, relevant IOCs, and the tactics, techniques, and procedures (TTPs) used by adversaries. By integrating threat intelligence, hunters can prioritize their efforts and focus on the most significant risks to their organization.
