Cyber threat hunting is the process of proactively and repeatedly searching, detecting and isolating threats that are flee from existing security solutions within a network or data set.
Threat hunting teams need threat intelligence plus a network person, an endpoint person, a malware analyzer, and a scalable bunch of tools. SANS defines threat hunting as a focused and iterative approach to searching out, identifying, and understanding adversaries internal to the defenders networks. These threats may be uncontrollable and often difficult or impossible to identify in advance.
When decoys are hit new threat intelligence is gathered and applied at wire speeds. In order to be successful, cyber threat hunting requires data, baseline information, and threat intelligence. Creating an effective threat hunting program requires a combination of the right tools and the right processes. It is also difficult to see the big picture of what is happening across the environment when security teams and tools operate in silos.
Organizations that employ threat hunting use an analyst-centric process to uncover hidden, advanced threats missed by automated, preventative and detective controls. Analysis is a key component of an effective threat hunting strategy, but many analysts are too involved with manual processes to research potential new indicators. Cyber threat hunting is the practice of searching proactively and iteratively through a network or data set to detect and isolate advanced threats that evade automated solutions.
Organizations are increasingly aware of the impact of insider cyber threats, but most are more prepared to respond to external cyber threats. Enterprise-wide threat hunting sounds like a daunting task and for inexperienced forensic analysts it certainly can be. Behavioral analysis is just one step of the malware analysis process that can be helpful.
Cybersecurity professionals recognize that proactively hunting threats will reduce the overall risk to the organization. As new threats emerge, security solutions that use artificial intelligence have to be re-trained in order to keep up. Cyber threat hunters are information security professionals who proactively and iteratively detect, isolate, and neutralize advanced threats that evade automated security solutions.
Effective cyber security monitors the threat landscape to identify which threats pose the most significant risk and utilize controls to minimize the likelihood of occurrence. Mission is to provide your organization with a highly mature detection and response capability designed to mitigate against. Through the use of these standards, organizations enable higher levels of automation in information-sharing, leading to a smarter shared response to cyber threats.
Threat hunting can and should be a part of your cybersecurity efforts, but the idea of starting a threat hunting and monitoring program can be intimidating. Threat hunting also requires specific knowledge and expertise which limits the practice to a few highly skilled analysts. The final threat hunter activity is to secure the environment from future attacks. Threat hunting is the step-by-step approach of proactively looking for signs of malicious activity within enterprise networks, without having initial knowledge of specific indications to look for, and subsequently ensuring that the malicious activity is removed from your systems and networks.
