As businesses expand, the complexities of managing security operations grow as well. Threat intelligence plays a crucial role in addressing these challenges by offering the insights needed to protect against emerging threats.
In a recent episode of the CheckItOut podcast, industry experts Gavin Rae, Senior Security Solutions Engineer at Rapid7, and Pete Livingstone, Security Specialist at The Missing Link, discussed the vital role threat intelligence plays in modern security strategies. Their conversation highlighted how effective threat intelligence can transform security operations and provide the necessary defence against today's evolving threats. In this blog post, we’ll share some of their key insights and offer practical guidance on how you can integrate threat intelligence into your security framework.
The growing importance of threat intelligence
Threat intelligence involves collecting and analysing information about potential threats to an organisation. It equips security teams with the necessary insights to detect, respond to, and mitigate cyber threats effectively. By integrating threat intelligence into your Security Operations Centre (SOC), your business can enhance its ability to monitor and defend against sophisticated attacks.
The process of threat intelligence can be best understood through the concept of "The Intelligence Cycle," which outlines the key phases of effectively leveraging threat intelligence: Direction, Collection, Analysis, and Dissemination. The image below illustrates this cycle, showing how each phase contributes to a comprehensive security strategy.
Why the shift from traditional automation to Generative AI is significant
The transition from traditional automation to GenAI marks a pivotal moment in the evolution of workplace technology. Traditional automation involves programming machines or software to perform specific, repetitive tasks based on predefined rules and logic. While beneficial in optimising processes, reducing errors, and saving time in routine operations, it has several limitations:

Each phase of The Intelligence Cycle plays a crucial role in transforming raw data into actionable insights. By following this cycle, your organisation can continuously improve its threat detection and response capabilities, ensuring you stay ahead of potential threats.
The rise of zero-day vulnerabilities
One significant concern raised in the podcast is the alarming increase in zero-day vulnerabilities and exploits. These are vulnerabilities that are unknown to the software vendor and remain unpatched, making them prime targets for attackers. With the rapid rise in cyber threats, zero-day vulnerabilities are being exploited at an unprecedented rate. Large organisations, particularly those with diverse and decentralised networks—such as those in manufacturing and healthcare—are especially vulnerable. Managing patches and updates across various devices in these complex environments can be challenging, leaving critical systems exposed to potential attacks.
Challenges in vulnerability management
Maintaining up-to-date patches across all devices is often easier said than done, especially in environments with various device types and management systems. As Pete Livingston highlighted, the decentralised nature of these environments makes it difficult to track and secure every device, creating numerous touchpoints for potential attacks. Attackers can easily exploit unpatched devices, using them as entry points to compromise the entire network.
The ransomware threat
Ransomware attacks have been steadily increasing, with payments exceeding $1 billion in 2023. High-profile incidents, such as the attacks on Medibank, have brought ransomware into the spotlight. Despite government recommendations against paying ransoms, many companies face difficult decisions when their data is held hostage. Refusing to pay can lead to the immediate release of sensitive data on the dark web, compounding the impact of the initial attack with further reputational and financial damage, not to mention significant business disruption and data breaches.
Multi-factor authentication (MFA) as a defence
Implementing multi-factor authentication (MFA) is a critical step in securing your organisation's access points. However, many companies struggle with the complexity of deploying MFA comprehensively across all users and systems. The challenge often lies in managing multiple user accounts, service accounts, and legacy systems, making widespread deployment difficult. As Gavin explains, the inconvenience of MFA for users can also be a barrier, yet it remains an essential defence against compromised access by adding an extra layer of security and making it more difficult for attackers to gain unauthorised entry.
Integrating threat intelligence into security operations
Integrating threat intelligence into your company’s security framework provides the critical "eyes and ears" needed to detect and respond to emerging threats. This intelligence extends beyond traditional vulnerability management and penetration testing, offering a more comprehensive view of the threat landscape. By monitoring critical assets such as domains, brand names, VIP users, external portals, and critical suppliers, you can identify potential threats early and take proactive measures. This enhanced visibility supports early threat detection and more informed decision-making, allowing your organisation to stay ahead of evolving risks.
Enhancing security with early detection and strategic decision-making
Integrating threat intelligence into a company's security framework involves several layers of complexity, extending beyond traditional vulnerability management and penetration testing to provide a comprehensive view of potential threats. A key benefit of this approach is the enhancement of early threat detection, which allows organisations to respond more effectively and potentially prevent significant damage. By monitoring critical assets such as VIP users, external portals, and critical suppliers, threat intelligence supports informed decision-making. As Pete emphasises, having prepared playbooks and standard operating procedures (SOPs) is essential for guiding the response to threats. These tools enable security teams to make quick, informed decisions, whether escalating an incident internally or involving external resources.
Threat intelligence is no longer just an optional component of a security strategy—it's a necessity. By incorporating it into your security operations, you can gain a deeper understanding of the threats you face and make more informed decisions to protect your assets. As the threat landscape continues to evolve, the ability to detect, analyse, and respond to threats in real-time will be critical to maintaining robust security defences.
