With the rise of digital technology and social media , cyber crimes have escalated rather quickly, with every passing moment. In a dystopian situation like this, the need for cyber threat intelligence has only become essential. But what is cyber threat intelligence exactly and what does it entail ?
Here’s a comprehensive guide about what is cyber threat intelligence and what we can expect from this tech, however, let us first understand what does cyber threat mean?
A cyber threat refers to any malicious act that is intended to damage data, steal data, or cause interference in digital life in general. Cyber threats can come from various agents, including hackers, criminals, and even insiders. Common cyber threats are: malware (like viruses and ransomware), phishing attacks, denial-of-service (DoS) attacks, and so on. With the growing digital dependence, the range and sophistication of cyber threats also shoots up.
In a response to these cyber threats, cyber threat intelligence has come up.
Cyber threat intelligence is a technology that uses data collection and analysis retrieved from threat history to block and repair cyber attacks on the target network.
Note that, cyber threat intelligence itself isn’t a hardware-based solution. Rather, this strategic intelligence involves techniques and methods and is a crucial part of an organization’s overall security architecture.
A cybersecurity system depends on threat intelligence and analysis to ensure it monitors and detects as many attacks as possible.
Cyber Threat intelligence helps one understand the threats and prevent or mitigate attacks on their network. The cyber threat intelligence system gets hold of threat data collection like who or what is attacking your network, why they are choosing you as a target, and how to spot signs that your system has been compromised. The benefits of cyber intelligence and analysis go beyond the IT team, analysts, and administrators. With a proper action-focused cyber threat intelligence system, the entire organization can be kept safe and resistible to such attacks.
When dealing with cyber threat intelligence, pick up on some of the indicators and signs of cyber threats. These signs include suspicious IP addresses, URLs, or domain names known for attacks; on interacting with these, a network's security can be easily breached. Apart from these usual signs, certain emails with specific addresses, subjects, or attachments can signal a potential compromise.
As mentioned above, certain filenames, file hashes, IP addresses, dynamic link libraries (DLLs), or registry keys are common indicators of threats. The analysts within a cybersecurity intelligence system maintain a list of common indicators of compromise and other tools that threat actors use and then filter out potentially dangerous communications and other network activity.
Taking into account, the indicators of compromise, threat intelligence and analysis is leveraged to improve the network security of the organization.
Thus, data collection is one of the primary methods of securing a network. With the right tools, cyber intelligence security analysts can use threat data feeds and technical information about the organization’s network and come up with a comprehensive protection plan for the organization.
Listed below are the different types of Cyber Threat Intelligence:
Operational Threat Intelligence: Operational threat intelligence is centered on specific threats and ongoing campaigns. It provides real-time insights and actionable recommendations to manage security vulnerabilities and understand attack techniques. operational intelligence analyzes past attacks and identifies patterns in threat actors' tactics, techniques, and procedures (TTPs), and understands the 'who', 'why', and 'how' of each cyber attack.
Strategic Threat Intelligence: Strategic threat intelligence gives a broad view of the threat landscape. It includes long-term trend analysis, identifies major risks that could lead to future attacks, and provides high-level insights into cybersecurity threats influenced by geopolitical factors and industry trends. This type of intelligence supports informed decision-making by non-technical stakeholders, such as company boards, guiding overarching security strategies.
Technical Threat Intelligence: Technical threat intelligence deals with specific technical details of threats. It focuses on indicators of compromise (IoCs), malware signatures, IP addresses, and other technical artifacts. The aim is to provide detailed information on vulnerabilities and malware behavior, including delivery mechanisms and potential impacts on systems. Technical intelligence is crucial for IT and security teams to effectively detect, respond to, and mitigate cyber threats.
Tactical Threat Intelligence: Tactical threat intelligence concentrates on the tactics, techniques, and procedures (TTPs) used by threat actors. It provides actionable insights into their methods, strategies, and current activities. Tactical intelligence helps organizations anticipate and prepare for specific threats, adapting their defenses to evolving attacker behaviors.
The primary benefit of a cyber threat intelligence program is it ensures the organization is prepared and proactive. With a comprehensive threat intelligence in place, an organization can access a storehouse of technical information gathered from around the world, and human knowledge that can significantly strengthen an organization’s defenses.
A threat intelligence program gives better incident response times. Cyber Threat Intelligence enhances communication between the IT team and stakeholders, and provides a threat landscape for those who may not be familiar with the details of cybersecurity.
Thus, cyber threat intelligence offers invaluable benefits to organizations of all sizes and sectors. By processing and analyzing data on potential threats, cyber threat intelligence provides a deep understanding of attackers and their methodologies, empowering proactive defense strategies.
Small to midsize businesses gain access to critical threat information that enhances their network security, typically beyond their own resources. Large enterprises utilize intelligence to analyze threat actors and their tools comprehensively, improving incident response and mitigation efforts. For security analysts and operations centers, threat intelligence prioritizes incident response by assessing risks effectively.
Ultimately, executives can use this intelligence to grasp the company's cybersecurity risks, their operational impacts, and make informed decisions to safeguard organizational assets.
What is cyber threat intelligence (CTI)?
Cyber threat intelligence (CTI) involves gathering, analyzing, and interpreting data about potential or current cyber threats that could harm an organization. It provides actionable insights into threat actors, their tactics, and indicators of compromise (IoCs).
Why is cyber threat intelligence important?
CTI helps organizations anticipate, detect, and respond to cyber threats effectively. It enables proactive defense strategies, enhances incident response capabilities, and informs decision-making at all levels of the organization.
What types of cyber threat intelligence exist?
There are four main types: Strategic CTI offers a broad view of the threat landscape. Tactical CTI focuses on specific threat tactics and techniques. Technical CTI provides detailed technical data such as IoCs and malware analysis. Operational CTI focuses on ongoing threats and campaigns.
How can small to midsize businesses (SMBs) benefit from CTI?
SMBs can access threat information that may otherwise be beyond their resources. CTI helps them understand and mitigate cyber risks, improving overall security posture without extensive internal expertise.
How do large enterprises utilize cyber threat intelligence?
Large enterprises leverage CTI to conduct in-depth analysis of threat actors and their tools, enhancing incident response and threat mitigation efforts across complex infrastructures.
Who benefits from cyber threat intelligence within an organization?
Security analysts use CTI to prevent and detect threats more effectively. Security operations centers (SOCs) prioritize incident response based on threat intelligence. Intelligence analysts track threat actors targeting organizational assets. Executive management gains insights to make informed decisions about cybersecurity risks and strategies.
