Threat hunting: What is it?
Threat hunting is the practice of identifying cyber threats that go unnoticed inside a network or data, including endpoints. The procedure entails delving deeply into the environment in order to identify harmful actors.
Threat hunting is crucial for avoiding such attacks. Attackers or hackers may remain undetected within a network for months, secretly collecting data login passwords and eavesdropping on your private information.
The following actions must be taken to conduct an effective threat search:
1. The Trigger: When advanced detection systems discover unusual behavior that may indicate malicious activity, a trigger alerts threat hunters to a specific computer or network region for further investigation. Frequently, a thought about a new threat serves as the impetus for proactive hunting. For example, a security team might look into future threats that can get around current defenses by using fileless malware technology.
2. Investigation: During the investigation phase, the threat hunter makes extensive use of technologies such as EDR (Endpoint Detection and Response) to assess a system’s vulnerability to hostile intrusion. The investigation will go on until it is clear that the activity is not harmful or that all of the information about the bad behavior is known.
3. Resolution: Operations and security teams employ malicious activity information during the resolution phase to react to incidents and minimize risks. Data from both good and malicious behavior can be used to make automation systems more effective without needing more human help.
Cyber threat hunters use this procedure to gather information about attackers’ tactics, and objectives. Also, they use the information they get to learn about an organization’s security environment, predict future security improvements, and fix existing vulnerabilities.
The importance of threat hunting
Investigate security incidents in a proactive manner
In the end, the goal of threat hunting is to identify cybercriminals who have already gained access to the organization’s systems and networks. It may assist in proactively detecting attackers who have already infiltrated the network’s defenses and established a hostile presence. The present cybercriminals are being hunted down with the use of hunting.
Speeds up the investigation
Threat hunting gives a security team more information about an incident, from figuring out how big it is to finding out what caused it and predicting how bad it will be. An active approach, such as analyzing computer network traffic to look for malicious content to investigate possible compromises and improve cyber defenses, can help gather important data that can be used to look into after-the-fact incidents. This will help you figure out what you’ve learned and fix any problems.
Improves the efficiency of SOCs
Threat hunting has the advantage of being human-centered, proactive, iterative, and analytical. The analysts’ resourcefulness and skill to scrutinize and assess data, together with the tools and frequent monitoring, and behavior-pattern searching, results in fewer false positives and wasted time.
Threat intelligence, also called cyber threat intelligence, is information an organization uses to understand the risks that have targeted, will target, or are currently attacking them. This data is used to train for, stop, and detect cyberattacks that try to take advantage of valuable resources.
In a world where a certain number of cyber threats might cause a company to collapse, threat intelligence can be used to assist businesses in many ways. It can gather useful information about these threats, establish effective defensive systems, and manage the risks that might harm its operations and reputation. Cyber threat intelligence gives you the power to fight back more quickly against specific threats and attacks.
Threat intelligence is evidence-based information about an actual or developing threat or hazard to assets, including context, processes, indications, consequences, and actionable recommendations. This information may be utilized to judge how the subject should respond to the threat or risk.
The importance of threat intelligence
Reducing data loss: Because threat intelligence aids in prohibiting known malicious domains and IP addresses belonging to global threat actors, the blockage stops known threat actors from infiltrating your environment using the same malicious IP addresses and domains. As a result, such attackers will be unable to implant information-stealing malware or ransomware into your environment, boosting the security of your data.
Keeping up with evolving modes of attack: Threat intelligence also provides information on the most recent attack methods. Phishing emails, for example, are used to launch the majority of cyberattacks these days. This information may be used to prevent intruders from gaining access. In the case of phishing, businesses might set up awareness programs for their employees so that phishing doesn’t lead to a cyber attack.
