Instead of waiting for warnings to go off, cyber threat hunting is a proactive cybersecurity technique that entails actively looking for risks within a network. Similar to a cybersecurity investigator, it carefully examines the online environment for indications of malevolent behavior.
Why is it important to hunt for cyber threats?
- Proactive Defense: Threat hunting enables businesses to recognize and neutralize threats before they have a chance to do serious harm, in contrast to typical security procedures that emphasize reactive actions.
- Advanced Threat Detection: Conventional security techniques frequently fail to detect advanced persistent threats (APTs) and other complex attacks. By examining network traffic, logs, and other data sources, threat hunters can find these hidden dangers.
- Better Security Posture: Organizations may lower the risk of breaches and improve their overall security posture by proactively recognizing and mitigating threats.
The Method of Cyber Threat Hunting
1. Specify the Hunting Area:
- Determine the organization's vital resources and systems.
- Choose which dangers and offensive methods to concentrate on.
- Clearly define the hunting process's goals.
2. Gather Knowledge:
- Gather pertinent threat intelligence from a range of sources, including industry publications, threat intelligence feeds, and security forums.
- Keep abreast with the most recent threats and cybercriminals' strategies.
3. Determine Possible Compromise Indicators (IOCs):
- Create a collection of warning signs for potential compromises, such as malicious code, unauthorized access attempts, or odd network activity.
4. Carry Out the Hunt:
- Look for IOCs and other irregularities using a variety of methods and technologies.
- Look for unusual activity in network traffic, logs, and security event logs.
- Use threat hunting platforms and technologies to speed up detection and automate the process.
5. Confirm Results:
- Verify the veracity of any possible threats by doing a thorough investigation.
- To develop a thorough grasp of the danger, correlate data from several sources.
6. React and Clean Up:
- Take prompt action to limit and lessen the consequences of a proven threat.
- Put in place the proper security measures to stop such assaults in the future.
- For future use and enhancement, record the incident response procedure.
Technologies and Instruments for Cyber Threat Hunting
- Information and Event Management for Security (SIEM) Instruments: To find irregularities, gather, examine, and correlate security event logs.
- Platforms for Security Orchestration, Automation, and Reaction (SOAR): Simplify incident response and automate repetitive processes.
- Threat Intelligence Platforms: Facilitate the study of threat actor tactics, methods, and procedures (TTPs) and grant access to threat intelligence streams.
- Instruments for Endpoint Detection and Response (EDR): Keep an eye out for harmful activities on endpoint devices and take appropriate action.
- Tools for Network Traffic Analysis (NTA): Examine network traffic to spot possible threats and questionable activities.
Organizations may proactively fight against cyber threats and safeguard their precious assets by integrating cyber threat hunting into their security policies.
