I’ve seen the devastating effects of cyber threats on unsuspecting victims. Whether it’s identity theft, corporate espionage or a full-scale cyber attack, the impact on a business can be disastrous. It’s crucial that businesses take proactive measures to prevent cyber attacks and defend their assets. The key to successful cyber defense is intelligence – but not just any intelligence. There are three levels of intelligence in cybersecurity that businesses need to be aware of, and I’m going to break them down for you. It’s time to arm yourself with knowledge, understanding the different levels of intelligence cybersecurity is vital for protecting your business from cyber threats.

What are the three levels of intelligence cybersecurity?

Understanding the Three Levels of Cyber Threat Intelligence

Cybersecurity is an integral part of any organization that uses the internet for its business operations. Detecting and mitigating cyber threats is a complex task that requires a combination of technology, processes, and people. To achieve effective cybersecurity, companies must have a comprehensive understanding of the various types of cyber threats that they face. Cyber Threat Intelligence (CTI) is a critical tool that organizations can use to understand and defend against cyber threats.

CTI is classified into three categories: Tactical, Operational, and Strategic. Each of these levels provides different insights into the various types of cyber threats that an organization may face. Tactical CTI provides specific indicators and actions that can be used to guide network-level actions and remediation. Operational CTI provides a wider view of the threat landscape and is used to guide operational and tactical decision-making. Strategic CTI provides high-level insights into the geopolitical and economic factors that shape cyber threats and is used to inform long-term cybersecurity strategy.

Tactical Cyber Threat Intelligence Explained

Tactical CTI is the most granular level of CTI. It provides specific technical indicators that can be used to identify and mitigate cyber threats. Some examples of tactical CTI include:

IP Addresses: IP addresses that are known to be associated with malicious activity
Domains: Domains that have been flagged as associated with cyber attacks
File Hashes: Unique digital fingerprints of files that can be used to identify malware
Malware Behavior: Information on how malware operates
Exploit Kits: Kits that are used to automate the exploitation of vulnerabilities

Tactical CTI is useful for guiding immediate network-level actions, such as blocking IP addresses associated with malicious activity or blocking access to domains that are known to be associated with cyber attacks.

Operational Cyber Threat Intelligence Defined

Operational CTI provides a broader view of the threat landscape. It is used to guide operational and tactical decision-making. Operational CTI focuses on understanding the tactics, techniques, and procedures (TTPs) of cyber criminals. It seeks to answer questions such as:

What types of attacks are being executed?
What targets are being attacked?
What vulnerabilities are being exploited?
What malware is being used?

Operational CTI can be used to identify patterns in the threat landscape and to guide the development of operational and tactical cybersecurity strategies.

Strategic Cyber Threat Intelligence and its Importance

Strategic CTI is the highest level of CTI. It provides a high-level view of the geopolitical and economic factors that shape cyber threats. Strategic CTI seeks to answer questions such as:

What are the motivations behind cyber attacks?
What nation-states are most likely to launch cyber attacks?
What types of attacks are nation-states most likely to launch?

Strategic CTI is used to inform long-term cybersecurity strategies. It can be used to identify emerging threats and to develop proactive cybersecurity measures.

The Role of Tactical Cyber Threat Intelligence in Network-Level Actions

Tactical CTI is critical for guiding network-level actions. When an organization detects a network-level compromise, it needs to take immediate action to mitigate the threat. Tactical CTI provides specific indicators that can be used to identify and block malicious activity. For example:

IP Address Blocking: When an IP address associated with malicious activity is detected, it can be immediately blocked
Domain Blocking: When a domain associated with malicious activity is detected, it can be immediately blocked
File Hash Blocking: When a file with a known malicious hash is detected, it can be immediately blocked

Tactical CTI provides actionable insights that can be used to prevent further damage from cyber threats.

Leveraging Operational Cyber Threat Intelligence for Effective Cybersecurity

Operational CTI is useful for understanding the broader threat landscape. By identifying patterns in the types of attacks, targets, vulnerabilities, and malware being used, organizations can develop more effective operational and tactical cybersecurity strategies. For example, if an organization notices an increase in phishing attacks targeting employees, it can develop a targeted awareness campaign to educate employees about the risks of phishing.

Operational CTI can also be used to identify vulnerabilities that are commonly exploited by cyber criminals. By patching these vulnerabilities, organizations can reduce their risk of being compromised.

How Strategic Cyber Threat Intelligence Can Help in Formulating Cybersecurity Strategy

Strategic CTI provides high-level insights into the geopolitical and economic factors that shape cyber threats. By understanding these factors, organizations can develop proactive cybersecurity strategies to address emerging threats. For example, if an organization believes that a nation-state is likely to launch cyber attacks, it can develop proactive measures to mitigate this threat. These measures may include:

Developing relationships with government agencies: By developing relationships with government agencies, organizations can gain insights into emerging threats
Investing in advanced cybersecurity technologies: Advanced technologies such as Artificial Intelligence and Machine Learning can help organizations detect and mitigate cyber threats more effectively
Increasing employee awareness: Educating employees about the risks of cyber threats can help prevent them from becoming a target

Strategic CTI provides a forward-looking perspective on the cybersecurity threat landscape. By leveraging this information, organizations can develop effective strategies to defend against cyber threats.

In conclusion, CTI is an essential tool that can be used to detect and mitigate cyber threats. By understanding the three levels of CTI, organizations can develop more effective cybersecurity strategies. Tactical CTI provides specific indicators and actions that can be used to guide network-level actions and remediation. Operational CTI provides a wider view of the threat landscape and is used to guide operational and tactical decision-making. Strategic CTI provides high-level insights into the geopolitical and economic factors that shape cyber threats and is used to inform long-term cybersecurity strategy. By leveraging these levels of CTI, organizations can develop more effective and proactive cybersecurity measures.
