A malicious attacker may attack any organization, regardless of size, in search of financial gain or information. The situation is critical, and 68% of companies believe their cybersecurity risks are worsening. In the middle of this, it is essential to implement multiple threat monitoring and mitigation strategies. So let’s understand the threat hunting and incident response in this article.
Understanding Threat Hunting and Incident Response
Threat hunting and incident response are emerging approaches to threat monitoring and mitigation. These strategies enable an organization to be attentive and preventive of itself from cyber threats, security breaches, and system vulnerabilities.
While the concepts of threat hunting and incident response are frequently used together, they have different meanings, approaches, and objectives when it comes to adopting cybersecurity within an enterprise.
Threat hunting is a cybersecurity activity that attempts to find and prevent malicious activity in an organization’s information systems using preventive techniques and advanced technologies. It works on the assumption that attackers have already exploited the organization’s essential systems. This assumption is predicated on the fact that these attackers have already discovered a means to avoid detection by existing tools and techniques. Therefore an active effort is necessary to root out the threats.
An organization’s methodology to respond to and manage a cyberattack is incident response. A cyberattack or security breach may cause customer chaos, copyright issues, organizational resources and time hampering, and degrading brand equity. The objective of incident response is to minimize damage and go back to normal as soon as possible. After a security breach, having a well-defined incident response strategy can help limit attack damage and save expenses and time.
In brief, both threat hunting and incident response are advantageous to any cybersecurity system. Threat hunting protects an organization from cyber attacks and data theft, and incident response helps organizations mitigate and manage those attacks.
Threat Hunting vs. Incident Response
The vulnerability assessment scenario is constantly evolving, resulting in a dramatic increase in the number of security breaches emerging every day. And these cyber attacks are capable enough of causing severe reputational and financial losses to any organization. These kinds of cyber-attacks cause harm to the reputation and economic loss, and the recovery process and the quantity of money required are typically enough to destroy that organization.
A thorough threat hunting and incident response plan is one way to ensure security from these kinds of long-term collapsing damages. Now, let’s look at the differences between threat hunting and incident response from several perspectives.
Let’s look at the goals of threat hunting and incident response.
Threat hunting methodologies: The threat hunting methodologies comprise three phases: an initial trigger phase, followed by an investigation, and finally, a resolution.
Incident response methodologies: The incident response methodologies work on the six essential steps, which are: preparation, identification, containment, eradication, recovery, and lesson learned.
Threat hunting tools: There are three types of tools used in threat hunting.
a) Analytics-driven: These kinds of tools are used to construct risk scores and other assumptions. Examples of analytics-driven tools are RITA and VECTRA
b) Intelligence-driven: All data and reporting are gathered and applied to threat hunting using intelligence-driven technologies. Examples of intelligence-driven threat hunting tools include YARA, CrowdFMS, Botscout, and Machinae.
c) Situational awareness-driven: A company’s trends can be examined using risk assessment analysis, indicating how much threat they carry. Examples of situational awareness-driven tools are AIEngine (Artificial Intelligence) and YETI.
Incident response tools
Security issues are on the rise in organizations, and these occurrences have become unavoidable in today’s technology-driven world. As a result, the incident response team requires strong tools to overcome and control security incidents. Examples of the incident tools are LogRhythm, Sumo Logic, InsightIDR, CB Response, and IBM QRadar.
So we can say that threat hunting is a proactive, assumption activity that seeks to identify and neutralize attacks that have already entered the network or essential systems. On the other hand, incident responses are reactive. In most cases, an intrusion detection system or procedure issues a warning, and organizations investigate the issue until the threat is neutralized and the damages are minimized.
This suggests that threat hunting is exclusively concerned with detection; it is also an assumption approach to prevention. Threat hunting is most useful when it can help the organization improve its security infrastructure by protecting threat vectors and preventing problems before they happen.
Threat hunting is most efficient when used to motivate appropriate modifications in design and configuration. In contrast, a comprehensive incident response capacity focuses on quickly identifying incidents and evaluating and fixing issues as they occur. This lowers the risk of future attacks while also strengthening incident response mechanisms.
