What Is Threat Intelligence?

At least for two decades, we have been witnessing relentless changes in the threat landscape towards growth and sophistication, with both rough actors and state-sponsored collectives devising sophisticated offensive campaings against organizations globally. In 2024, adversaries, on average, proceed with 11,5 attacks per minute. Simultaneously, it takes 277 days for SecOps teams to detect and contain a data breach, according to research by IDM and Ponemon Institute. One of the reasons for such a layoff is the massive talent shortage within the industry, with 71% of organizations having unfilled positions.

In view of the existing talent gap and ever-growing attack surface, it is essential to make informed decisions about proper prioritization and resource-effective cyber defense operations. 

Defining Threat Intelligence

Gartner states that threat intelligence, also known as cyber threat intelligence (CTI), is a crucial element of security architecture. It aids security professionals in detecting, triaging, and investigating threats, thus enhancing an organization’s security posture. By improving alert quality, reducing investigation times, and providing coverage for the latest cyber attacks and actors, CTI plays a vital role in modern cyber defense.

According to Gartner, threat intelligence is defined as “evidence-based knowledge (e.g., context, mechanisms, indicators, implications, and action-oriented advice) about existing or emerging menaces or hazards to assets.” In other words, threat intel is comprehensive and actionable data aimed at anticipating and thwarting organization-specific cyber threats. CTI empowers security teams to take a data-driven approach to proactively and effectively withstand cyber attacks before they escalate while facilitating detection and hunting efforts. 

A study by Statista forecasts that the CTI market will exceed 44 billion U.S. dollars by 2033, highlighting the increasing importance of informed, data-driven defenses in contemporary business strategies. This prediction aligns with the outcomes from the Recorded Future 2023 State of Threat Intelligence report, revealing that 70.9% of respondents have a dedicated team for gathering and analyzing threat intelligence.

Integrating threat intelligence into your cybersecurity strategy can be challenging. It requires prioritizing your organization’s specific information needs and evaluating your security controls to effectively operationalize threat intelligence. Misusing CTI can result in an overload of alerts and an increase in false positives, highlighting the importance of proper implementation.

Threat Intelligence Types

Threat intelligence can be grouped into tactical, strategic, and operational depending on the organization’s objectives, parties engaged, specific requirements, and overall goals in a lifecycle scenario.

• Strategic threat intel provides high-level insights into the global attack surface and how an organization fits into it. It is mainly used for long-term decisions that transform the processes and foster the advancement of cybersecurity programs. Stakeholders leverage strategic threat intelligence to align organizational cybersecurity strategies and investments with the cybersecurity landscape.
• Tactical threat intel involves indicators of compromise (IOCs), such as IP addresses, domains, URLs, or hashes consumed by security controls but also used manually during investigations. It helps Security Operations Centers (SOCs) detect and respond to ongoing cyber attacks, focusing on common IOCs, like IP addresses linked to adversary C2 servers, file hashes from identified incidents, or email subject lines associated with phishing attacks. This type of threat intel assists in filtering out false positives and uncovering hidden attackers, aiding security teams in their daily SOC operations. In a nutshell, tactical CTI is intended to serve short-term decisions, like issuing urgent alerts, escalating cybersecurity processes, or adjusting configurations within the existing infrastructure.
• Operational threat intel, also known as technical CTI, enables organizations to proactively thwart cyber attacks by focusing on known adversary TTPs.  Information security leaders like CISOs and SOC Managers take advantage of this type of CTI to anticipate potential threat actors and implement targeted security measures to combat attacks that are most challenging the business.

Who Can Gain From Threat Intelligence?

Threat intelligence encompasses extensive and actionable data designed to anticipate and counteract threats specific to an organization no matter its size, industry, or level of cybersecurity maturity. CTI equips security teams with the data necessary to proactively and effectively defend against cyber attacks, facilitating both detection and response efforts and enabling businesses to gain a holistic understanding of existing threats or proactive measures not yet linked to cyber attacks.

For small and medium-sized businesses, threat intelligence provides a level of protection that might otherwise be unattainable. Large-scale enterprises with extensive security teams can reduce costs and skill requirements by using external threat intelligence, making their analysts more effective.

Depending on the type of threat intelligence, any member of a security team can make the most of CTI to elevate the organization’s defenses:

• Security and IT analysts can enhance detection capabilities and fortify defenses. They correlate CTI by collecting raw threat data and security-related details from a wide range of sources, including open-source CTI feeds, information exchange peer-driven communities, or internal organization-specific log sources. 
• SOC analysts correlate and analyze tactical threat intel to identify trends, patterns, and adversary behaviors and rank incidents by their risk and potential impact, which in turn improves the accuracy of threat identification and reduces false positives.
• Threat hunters rely on operational CTI in their hypothesis-driven investigations, providing insights into attacker TTPs to prioritize the most critical threats. They also leverage tactical threat intel to facilitate IOC-based hunting and document indicators of compromise linked to emerging and existing threats. CTI also facilitates proactive threat hunting, enabling detecting potential threats at the earliest attack stages before they cause significant harm. 
• CSIRT (Computer Security Incident Response Team) can leverage threat intelligence to accelerate incident response capabilities. Threat intelligence provides CSIRT with crucial insights into the latest threats, including IOCs and attack patterns used by malicious actors, to promptly identify and remediate incidents within the organization. By integrating CTI into their workflows, CSIRT can enhance the efficiency of incident prioritization and response, resulting in quicker actions and lessened impact from cyber attacks.
• Executive management, such as CISOs, SOC Managers, and other information security decision-makers, leverage strategic threat intel to gain comprehensive visibility into the threats most challenging the business. This fosters strategic planning to anticipate future threats and vulnerabilities and effectively mitigate their impact.

Threat Intelligence Lifecycle

CTI-related operation is a continuous process of transforming the raw data into actionable insights for informed decision making. The CTI lifecycle acts as a simple framework to enable SecOps departments to optimize their efforts and resources toward threat-informed cyber defense. Although the approaches might slightly vary, normally, the threat intelligence lifecycle consists of 6 major milestones resulting in an effective workflow and continuous feedback loop for improvement at scale.

1. Direction. At this stage, security teams establish the requirements and goals for a particular CTI operation. During this planning stage, teams create a roadmap, with goals, methodology, and tools defined depending on the needs of the parties involved.
2.  Collection. Once the goals and objectives are clear, teams can start the data collection process. This involves gathering data from various sources, including security logs, threat feeds, forums, social media, subject matter experts, etc. In fact, the idea is to collect as much relevant information as possible.
3. Processing. Once all the required information is available, the next stage of the lifecycle presumes its processing and organization into usable form. Normally, it includes evaluating data for relevance, filtering, removing irrelevant details, translating info from foreign sources, and structuring the core data for further analysis.
4. Analysis. Having a ready dataset at hand, teams proceed with the thorough analysis to convert disparate data pieces into actionable CTI, including threat actors profiling, threat correlation, and behavious analysis.
5. Dissemination. Once analysis is performed, at the dissemination phase teams ensure that key conclusions and recommendations are received by stakeholders.
6. Feedback. The final stage is receiving feedback from the parties and stakeholders involved to determine adjustments and improvements to be made during the next cycle.
