In today’s cybersecurity landscape, incident response has become a critical part of any organization’s security strategy. As cyber threats continue to evolve and become more sophisticated, organizations need to have effective incident response strategies in place to minimize the impact of security incidents.
According to CXOtoday.com, it is projected that the cost of global cybercrime will increase by 15% year-over-year over the next five years, reaching an estimated USD 10.5 trillion annually by 2025, up from USD 3 trillion in 2015.
Data breaches reached an all-time high in the third quarter of 2022, with approximately 15 million records being exposed. The education/research, government/military, and healthcare sectors are the top three sectors impacted by the growing attacks of cybercriminals. Check Point Research (CPR) notes that these sectors experienced an average of 2,148, 1,564, and 1,426 weekly attacks.
One way to improve incident response is by using threat intelligence, which provides valuable information about potential threats and can be used to inform incident response workflows.
In this article, we will explore the role of threat intelligence in incident response and discuss how organizations can use threat intelligence to improve their incident response strategies.
Understanding the Role of Threat Intelligence in Incident Response
According to Recorded Future, almost every industry today relies on digital technologies. The automation and interconnectedness they provide have transformed the world’s economic and cultural institutions. However, they have also introduced a new risk in the form of cyberattacks.
Threat intelligence, also known as open-source intelligence (OSINT), refers to the knowledge and information that can help prevent or reduce the impact of these attacks.
Threat intelligence plays a crucial role in incident response by helping organizations stay informed about the latest cyber threats and attack techniques. By providing detailed information about potential attackers, their motivations, and their methods of operation, threat intelligence enables organizations to better prepare for and respond to security incidents.
The information provided by threat intelligence can be used to identify vulnerabilities in existing security systems, develop more effective incident response plans, and improve overall security posture. Understanding the role of threat intelligence is essential for organizations looking to develop robust incident response strategies and protect their critical assets from cyber threats.

Identifying Relevant Sources of Threat Intelligence
Polaris Market Research states that the increase in cyber-attacks has resulted in heightened demand for the threat intelligence market. The threat intelligence sector provides beneficial solutions across various industries. With a predicted CAGR of 6.6% during the forecast period, the global market for threat intelligence was valued at USD 11.69 billion in 2021.
To identify relevant sources of threat intelligence, organizations should consider the following:
- Commercial vendors: Numerous commercial threat intelligence vendors provide a range of services, including threat data feeds, threat hunting services, and vulnerability assessments.
- Open-source tools: Open-source threat intelligence tools are freely available and can be used to collect and analyze threat intelligence data from a variety of sources.
- Internal data sources: Internal data sources, such as log files, network traffic data, and security alerts, can provide valuable information about potential threats and can be used to identify patterns and trends.
By leveraging these sources, organizations can gain a comprehensive understanding of the threat landscape and develop effective incident response strategies.
Analyzing and Contextualizing Threat Intelligence
Raw threat intelligence data can be overwhelming, and it is essential to identify relevant and actionable information to avoid information overload. This requires analyzing and contextualizing the data by correlating it with multiple sources, identifying patterns and trends, and assessing the credibility and accuracy of the data.
In doing so, organizations can gain a better understanding of the threat landscape and develop more effective incident response strategies that are tailored to their specific needs. This process also helps organizations identify emerging threats and proactively mitigate them.
Incorporating Threat Intelligence Into Incident Response Workflows
Threat intelligence can be used to update detection rules, identify indicators of compromise (IOCs), and guide incident response playbooks. By incorporating threat intelligence into incident response workflow, organizations can quickly and efficiently respond to potential threats and reduce the impact of incidents.
This integration of threat intelligence into incident response workflows helps organizations become more proactive, rather than reactive, in their approach to cybersecurity.
Using Threat Intelligence to Prioritize and Triage Incidents
Threat intelligence can provide insights into the severity and likelihood of threats, which can help incident responders prioritize incidents based on the level of risk they pose to the organization.
By doing so, incident responders can focus their efforts on the most critical incidents first, reducing the impact of potential threats. This approach allows organizations to allocate their resources more effectively and efficiently, ensuring that they are used where they are most needed.
Collaborating and Sharing Threat Intelligence With Peers
Sharing information can help identify common threat actors and tactics, and provide additional context and insights that may not be available from individual sources. This can lead to better threat detection and more effective incident response.
Additionally, collaborative efforts can help identify gaps in threat intelligence and encourage the development of new tools and techniques to improve threat detection and response capabilities.
However, it is essential to ensure that sensitive information is shared securely and appropriately.
Continuously Evaluating and Refining Incident Response Strategies
According to tech Tech Target, it is crucial to evaluate, review and update incident response processes regularly in response to changes in IT infrastructure, business operations, personnel, and the ever-evolving threat landscape. Outdated incident response plans can lead to confusion and undermine the effectiveness of the response procedures.
This may involve updating detection rules, refining incident response playbooks, and incorporating new tools and technologies. You also need to regularly conduct incident response exercises to test and refine incident response workflows, as well as to solicit feedback from incident responders to identify areas for improvement.
In conclusion, incorporating threat intelligence into incident response workflows can greatly enhance an organization’s ability to detect, respond to, and mitigate cyber threats. By understanding the role of threat intelligence, identifying relevant sources of data, analyzing and contextualizing information, and collaborating with peers, organizations can develop more effective incident response strategies.
Continuously evaluating and refining these strategies based on new insights and feedback is also crucial to stay ahead of evolving cyber threats. By leveraging threat intelligence as part of their incident response approach, organizations can better protect their systems, data, and reputation from potential attacks.
