Despite deploying security precautions to protect their networks from cyberattacks, numerous firms have experienced network breaches. Nowadays, threat actors use complex and sophisticated tactics to infiltrate a network, the impact of which may not be mitigated by traditional methods. The proactive procedure of checking the network for any hostile activity is referred to as cyber threat hunting.

Cyber threat hunting and cyber threat intelligence

Continuously monitoring the network for suspicious activity and gaps in the organization's ecosystem is required for cyber threat hunting. By analyzing previous data from a variety of sources, cyber threat hunting techniques keep a watch for potential new risks. Threat hunting techniques can discover, identify, and fix security flaws, vulnerabilities, and malicious behavior that normal security measures frequently fail to detect.

How to start hunting threats inside the Cyber or IT infrastructure?

Proactive preparation is the key to success in cyber security operations. It is critical to establish a solid foundation before beginning to develop the cyber threat hunting program.

A business is advised to take the following actions

• Plan a cyber-threat hunting program - To begin cyber threat hunting, map the security process to any existing security model, such as the MITRE ATT&CK architecture. It is also recommended that the security posture be assessed to see how vulnerable the organization is to hazards and attacks.
• Maturing the threat hunting program - After determining the level of cyber maturity, the next step is to decide whether the cyber threat hunting process should be carried out internally, externally, or a combination of both.
• Identifying and addressing gaps in tool and technology implementation -  Analyze the current tools and determine what is required for successful threat hunting and the effectiveness of preventative technology.
• Identifying and addressing security personnel training gaps - Threat detection necessitates the skills of an expert. If the organization lacks experienced internal specialists, it is recommended to use a third-party source.
• Adoption of a cyber-threat hunting strategy - Any firm must have a solid cyber threat hunting strategy which can help in mitigating the impact of cyberattacks on its infrastructure.

What kind of professionals can perform active cyber threat hunting?

Cyber threat hunting calls for knowledge of all the systems and data in use at the firm. This has to be combined with exquisite expertize in threat intelligence analysis, reverse engineering and malware analysis. Threat hunters must also be excellent communicators who can present their results and contribute to the business case for sustained threat hunting resources. It is preferable to put together a team of curious, analytical issue resolvers who have these talents and are motivated to further improve them. The willingness to keep learning is another essential quality of effective cyber threat hunters. Cyber threats are continuously changing, thus threat hunters must be dedicated to keeping their knowledge current by following researchers, participating in online groups, and attending industry forums, which enables them to learn about new strategies.

Advanced next-generation technology and human professionals work in unison to create an effective threat hunting process. To find any potential risks and harmful activity, the threat hunters need investigation tools and other inputs. These tools make it possible for threat hunters to find and examine the risks. For example, XDR (Extended Detection and Response) collects all the signals from the IT ecosystem and EDR (Endpoint Detection and Response) delivers inputs from the endpoint solution. These tools aid in the earlier identification of any possible threats.

Cyber threat hunters should be aware of the automated procedures, alarms, and behavior analyses that have already been run on the data to avoid duplicating work. Threat hunting may go down a lot of rabbit holes, therefore it demands agility. However, there should be a structured framework in place to direct the hunt and allow for any necessary withdrawal from the rabbit holes.
