What is cyber threat hunting?

• Cyber threat hunting is a proactive security strategy where experts search for hidden threats on a network that traditional security measures may miss.
• These experts use various methods such as investigating indicators of compromise, developing hypothesis-based hunts for new threats, and focusing on high-risk areas within an organization.
• Cyber threat hunting differs from reactive security methods that only respond after a threat is detected.
• Traditional security methods rely on comparing threat indicators to a database of known threats, while threat hunting is proactive and aims to prevent breaches.
  

  How does cyber threat hunting work?
  

• Threat hunting involves collaboration between threat hunters and advanced detection tools to identify hidden threats.
• Security analysts use their critical-thinking skills along with monitoring and analytics tools to detect threats within a network.
• Various threat hunting techniques include searching for insider threats, patching vulnerabilities, identifying known threats like advanced persistent threats (APTs), and implementing security incident response plans.
  

  Benefits of cyber threat hunting
  

• Proactive threat hunting can help identify and patch vulnerabilities before they are exploited, reducing successful breaches.
• It allows for careful analysis of data to detect anomalies indicating a breach, limiting the impact and duration of attacks.
• Cyber threat hunting techniques provide greater visibility and efficiency in security operations.

  Pros of threat hunting:

• Proactively identifies and patches vulnerabilities
• Limits the impact of breaches
• Improves security monitoring efficiency

  Cons of threat hunting:

• Requires a significant upfront investment in tools and cybersecurity talent
  

  Types of cyber threat hunting
  

• There are three main types of threat hunting: hypothesis-driven, unstructured, and situational hunting.
• Hypothesis-driven hunting involves formulating a hypothesis about a threat actor’s attack method based on indicators of attack.
• Unstructured hunting starts with exploration and looking for indicators of compromise in the system.
• Situational hunting focuses on specific resources or entities within an organization based on internal risk assessments.
  

  What is the cyber threat hunting process?
  

• The cyber threat hunting process involves hypothesis setting, investigation, and resolution/response phases.
• Threat hunters formulate hypotheses based on emerging security trends or indicators of attack.
• They use security tools to investigate vulnerabilities and malicious areas, then respond to threats using advanced technologies.
  

  Threat hunting tools and techniques
  

• Commonly used tools for threat hunting include security monitoring, advanced analytics, SIEM, XDR solutions, MDR systems, and pen testing.
• These tools help in detecting and responding to threats proactively and efficiently.
  

  Popular threat hunting solutions
  

• CrowdStrike, ESET, and Splunk are popular threat hunting solutions that offer a range of tools for different business sizes.
• These solutions provide effective threat hunting tools like SIEM, XDR, EDR, and MDR services to help companies protect against cyber threats.
