We all know that cyber security is an ever-growing concern, and it is essential for organisations and individuals to be aware of the latest cyber threats and how to protect against them. But what exactly is cyber threat intelligence (CTI), and how can it be used to improve our security posture? In this blog, we will explore the various aspects of CTI, from the basics of understanding what it is to the most advanced tools and services available.
What is cyber threat intelligence?
Cyber threat intelligence is the collection and analysis of data to identify and assess threats to an organisation's information systems. It is often used to inform decision-making and to provide early warning of potential cyber-attacks. CTI is used to detect, analyze, and respond to cyber threats in a timely and effective manner. It is also used to develop and maintain an organisation's security posture and improve incident response capabilities.
At its core, CTI is the practice of gathering and analysing threat data from various sources. This data can include information from open, closed, and underground sources. It can also include information from security vendors, international organisations, and other intelligence sources. Security professionals can identify potential threats and develop mitigation strategies by analysing this data.
The diamond model of cyber threat intelligence
The diamond model of CTI outlines the four steps that should be taken to gather and analyze threat data effectively. These steps are Collection, Processing, Analysis, and Dissemination.
- Collection: This step involves gathering data from a variety of sources. This can include open-source intelligence (OSINT), closed-source intelligence (CSINT), and underground sources.
- Processing: This step involves organising the data and making it easier to analyze. This can include categorizing data, applying filters, and using analytics.
- Analysis: This step involves analysing the data to identify patterns and trends that can be used to identify potential threats.
- Dissemination: This step involves sharing the threat intelligence with relevant stakeholders. This can include providing reports and alerts to security personnel and sharing information with other organizations.
Mitre ATT&CK as a tool for cyber threat intelligence
Mitre ATT&CK is a publicly available framework for understanding and addressing cyber threats. It comprises a matrix of tactics, techniques, and procedures (TTPs) attackers use. By understanding the TTPs used by attackers, organizations can better prepare for and respond to cyber-attacks.
Mitre ATT&CK provides organizations with access to detailed descriptions of the TTPs used by attackers. This can include information about malware, phishing campaigns, and exploitation techniques. Organizations can better identify potential threats and develop strategies to mitigate them by understanding the tactics and techniques attackers use.
The underground as a source of cyber threat intelligence
The underground is a term used to describe the dark web, which is a part of the internet that is not accessible through regular search engines and, indeed, cybercriminals forums. The dark web is a hotbed of criminal activity, and cybercriminals often use it to share information and tools.
The underground can be a valuable intelligence source, providing organizations with information about attackers' latest tactics and techniques. This can include information about new malware variants, vulnerabilities, and exploits. By monitoring the underground, organizations can stay ahead of potential threats and be better prepared to respond.
Cyber threat intelligence tools and services
Various tools and services are available to help organizations gather and analyze CTI. These tools can include malware analysis tools, intrusion detection systems, and intelligence analysis platforms.
Malware analysis tools can be used to identify and analyze malicious code, while intrusion detection systems can be used to detect and alert malicious activity. Intelligence analysis platforms can be used to analyze data from multiple sources and provide actionable insights.
Analysing and interpreting cyber threat intelligence
Once the data has been gathered and processed, it is time to analyze and interpret it. This can involve identifying patterns and trends and looking for indicators of malicious activity. By analysing the data, organizations can identify potential threats and gain insight into the tactics and techniques used by attackers.
Organizations can also use data visualization tools to make the data more understandable. This can include using charts, graphs, and other visualizations to help security personnel quickly understand the data.
Applying cyber threat intelligence
Once the data has been analyzed and interpreted, it is time to apply the intelligence. This can involve developing strategies to mitigate or prevent potential threats and improving existing security measures.
Organizations can also use intelligence to inform decision-making. This can include deciding which security measures are most effective and what areas must be addressed. The intelligence can also be used to develop security policies and procedures and train personnel on cybersecurity best practices.
Benefits of cyber threat intelligence
CTI can provide organizations various benefits, including improved security posture, enhanced incident response capabilities, and better decision-making.
Organizations can use CTI to understand better the threats they face and the tactics and techniques used by attackers. This can help them identify potential threats and develop strategies to mitigate them.
CTI can also be used to inform decision-making. This can include deciding which security measures are most effective and what areas must be addressed.
Cybersecurity best practices
Organizations should be aware of the latest cyber security best practices. This can include developing effective policies and procedures, implementing security measures, and training personnel on cyber security.
Organizations should also ensure that their systems are regularly monitored and patched. This can help to ensure that any vulnerabilities are identified and addressed quickly.
Finally, organizations should ensure that they have a response plan in place. This can include developing an incident response process and establishing a team of security personnel who can respond quickly to any potential threats.
Conclusion
Cyber threat intelligence is a valuable tool for organizations and individuals to understand and address cyber threats. Organizations can identify potential threats and develop mitigation strategies by gathering and analysing data from various sources. Additionally, organizations can use CTI to inform decision-making and to improve their security posture.
