What is Threat Intelligence

What is Threat Intelligence

Threat Intelligence is evidence-based information that helps organisations identify and understand potential cyber threats to their networks, systems, and data.The information may include :

• Mechanisms of an attack
• Identifying how an attack is happening
• Ways how different types of attacks can affect the business
• Action-oriented advice about how to defend against these attacks

Threat intelligence is typically derived from various sources, including internal security logs, external threat feeds, open-source intelligence, and human intelligence.By analysing and synthesising this information, organisations can proactively identify and respond to potential cyber threats, minimising the risk of data breaches, system compromise , and other security incidents.

Many forms of cyber attacks are common today including, zero-day exploits, malware , phishing, man in the middle of the attacks and denial of service attacks. New ways of attacking the system keep evolving. CTI helps organisations to stay informed about new threats so that they can be fully protected.

Threat Intelligence also helps to mitigate an attack that is in progress. The more an IT team understands about the attack , the better they will be able to make an informed decision about how to combat it.

Why is Threat Intelligence so Important?

Threat intelligence is essential because it empowers organisations to stay ahead of evolving threats, respond effectively to security incidents, make informed decisions, collaborate with others, and maintain regulatory compliance. By leveraging threat intelligence, organisations can enhance their overall cybersecurity resilience and protect their valuable assets and data from increasingly sophisticated cyber threats.

Threat intelligence is crucial in today’s increasingly complex and dynamic cybersecurity landscape for several reasons:

1. 1. Proactive Defence: Threat intelligence allows organisations to adopt a proactive approach to cybersecurity.

It helps identify emerging threats and trends, enabling organisations to enhance their security measures accordingly.
   2. Timely Incident Response: Having access to accurate and up-to-date threat intelligence enables organisations to respond swiftly and effectively to security incidents. By understanding the tactics, techniques, and procedures (TTPs) used by threat actors, organisations can develop effective incident response strategies and quickly detect and neutralise threats, minimising damage and reducing the impact of an attack.
   3. Enhanced Situational Awareness: Threat intelligence provides valuable insights into the overall threat landscape, both within an organisation’s specific industry and the broader cybersecurity ecosystem. This awareness allows organisations to understand the evolving threat landscape, identify potential risks and vulnerabilities, and make informed decisions regarding their cybersecurity posture and resource allocation.
   4. Strategic Decision-Making: By analysing threat intelligence, organisations can make informed decisions regarding their security investments, technology deployments, and resource allocation. It helps organisations prioritise security measures, allocate budgets effectively, and implement the most appropriate security controls to protect critical assets and infrastructure.
   5. Collaboration and Information Sharing: Threat intelligence encourages collaboration and information sharing among organisations, industry peers, and security communities. Sharing threat intelligence helps create a collective defence approach, where organisations can learn from each other’s experiences and leverage shared knowledge to strengthen their security posture collectively.
   6. Regulatory Compliance: Many industries and jurisdictions require organisations to maintain adequate cybersecurity measures and demonstrate due diligence in protecting sensitive information. Threat intelligence plays a critical role in meeting these compliance requirements by providing organisations with insights and evidence-based data to demonstrate their proactive security measures.

Who Benefits from Threat Intelligence?

Multiple stakeholders benefit from threat intelligence. Here are some key beneficiaries:

1. 1. 1. Organisations and Businesses: Threat intelligence provides valuable insights to organisations, helping them understand the evolving threat landscape and make informed decisions to enhance their cybersecurity posture. It enables organisations to proactively defend against threats, improve incident response capabilities, and prioritise security investments based on identified risks.
      2. Security Teams and Professionals: Threat intelligence empowers security teams and professionals with the knowledge and data needed to detect, analyse, and respond to security incidents effectively. It enhances their ability to identify indicators of compromise (IOCs), understand attack patterns, and stay up to date with emerging threats and vulnerabilities.
      3. Government and Law Enforcement Agencies: Threat intelligence plays a crucial role in national security efforts. Governments and law enforcement agencies benefit from threat intelligence to identify and track threat actors, prevent cybercrime, protect critical infrastructure, and share information with relevant stakeholders for coordinated response and defence.
      4. Information Sharing and Analysis Centers (ISACs): ISACs are industry-specific organisations that facilitate the exchange of threat intelligence among members. They provide a platform for collaboration, enabling organisations within a specific sector to share threat information, best practices, and mitigation strategies to collectively improve their cybersecurity posture.
      5. Security Vendors and Service Providers: Threat intelligence is a valuable resource for security vendors and service providers. It enables them to develop and update security solutions, technologies, and services based on emerging threats. By integrating threat intelligence into their offerings, they can better protect their customers and provide effective security solutions.
      6. Researchers and Analysts: Threat intelligence benefits cybersecurity researchers and analysts by providing them with valuable data and insights for conducting in-depth analysis, developing threat models, and advancing knowledge in the field of cybersecurity. This research contributes to the broader understanding of threat actors, attack techniques, and emerging trends.

In summary, threat intelligence benefits organisations, security teams, governments, ISACs, security vendors, researchers, and analysts by empowering them with timely and actionable information to defend against threats, improve security practices, and collaborate effectively in addressing the evolving cybersecurity landscape.

What are the different types of Threat Intelligence?

Threat intelligence can be categorised into several types, each serving a specific purpose in understanding and mitigating threats. Here are some common types of threat intelligence:

1. 1. 1. Strategic Intelligence: This type of intelligence focuses on providing a high-level view of the threat landscape. It includes information about threat actors, their motivations, capabilities, and the broader trends and developments in the cyber threat landscape. Strategic intelligence helps organisations develop long-term security strategies, understand the risks associated with specific threat groups, and prioritise resource allocation.
      2. Tactical Intelligence: Tactical intelligence provides more detailed information about specific threats and their characteristics. It includes indicators of compromise (IOCs), malware analysis, vulnerability information, and details about specific attack techniques and tactics used by threat actors. Tactical intelligence helps organisations detect and respond to ongoing or imminent threats by providing actionable information for security operations and incident response teams.
      3. Operational Intelligence: Operational intelligence focuses on providing real-time or near-real-time information about current and active threats. It includes alerts, threat feeds, and information about active campaigns, ongoing attacks, and emerging vulnerabilities. Operational intelligence enables organisations to take immediate action to protect their assets and respond swiftly to mitigate threats.
      4.
