Threat Intelligence in cybersecurity: A key role in incident response

Threat Intelligence is turning into a pervasive ability in numerous security aspects. It is a critical part of security engineering that helps security along with risk management, and specialized experts with the pace of exploding research. It was the time at a point when the dark web and malign activities were detonating, indicating the restrictions of the day’s security software. This exploration gives direction on the best way to utilize Threat Intelligence [TI] capacities. Gartner has reported some of the key findings for TI as follows:

  • Threat intelligence (TI) improves an organization’s detection and response capability by increasing alert quality, reducing investigation time, and adding coverage for the latest attacks and adversaries.
  • Modern security tools can ingest and leverage threat intelligence. However, they often don’t include guidance on the best way to utilize it.
  • Using threat intelligence improperly will result in more noise and false positives. Proper upfront planning for TI usage is critical. [Reference]

Threat intelligence minimizes the time that security teams spend in reactive mode by enabling several important capabilities:

  • Identifying and dismissing false positives or other irrelevant alerts automatically
  • Enriching alerts with real-time context across open web and dark web sources
  • Compiling information from internal and external data sources to identify and analyze genuine threats
  • Scoring threats according to an organization’s specific needs, infrastructure makeup, and in-the-wild details of the attack methods being used.

With these capabilities, threat intelligence provides incident response teams with actionable insights to make faster and better decisions that matter. At the same time, threat intelligence helps reduce the tide of irrelevant and unreliable alerts that typically make incident response so difficult and overwhelming. [Reference]

With threat intelligence becoming more than an option, TI has definitely become a mandatory feature that most security organizations have started to focus seriously. The Incident Response [IR] process doesn’t end with an attacker’s defeat. Often, threat actors make sloppy mistakes and leave traces of data behind that the IR team can use to build further intelligence on their specific TTPs, motivations and motives. For example, they can access the file hashes left behind by a threat actor’s malware, collect all related hashes for similar malware variants in the same malware family, see how and where the malware was acquired, and hunt for similar malware variants on a client’s network with an endpoint agent. In doing so, the team can unearth dormant or active attacks fueled by data from past incidents.

Time is one of the most restrictive factor of incident response efforts. If IR teams are stretched thin during a significant incident and lack the time to think through all the various required response measures, some network gaps or system vulnerabilities could stay open too long, inviting additional attacks or campaigns. Shockingly, a large number of the most well-known third-party risk management practices employed today are falling behind security necessities. Static assessments of risk, like audit reviews and security testament confirmations, are as yet significant, however they frequently lack context and aren’t always timely.

There’s a requirement for a solution that offers continuous update on the real danger scenario. Threat intelligence is one approach to do precisely that. It can give straightforwardness into the risky conditions of the one deals with, giving continuous cautions on threats and changes to their risks and giving you the context you need to assess your relationships
