Threat Intelligence

What is threat intelligence?

Threat Intelligence (TI), or threat intelligence, refers to the collection, analysis and interpretation of information about potential or actual threats that could target a company or organization. The goal is to provide security managers with relevant, actionable information to prevent or respond to attacks. This information can come from a variety of sources: Hacker forums, darknet, social networks, malware analysis or publicly available reports. Threat Intelligence is designed to help organizations take preventive action before threats become harmful.

Why is threat intelligence important?

Threat intelligence is critical because it supports a proactive security strategy. Instead of waiting for an incident and then reacting, threat intelligence allows you to anticipate threats and act in advance. Some of the key benefits are:

• Early detection of threats: By collecting and analyzing threat intelligence, companies can identify potential attackers before they strike.
• Protection against zero-day attacks: TI helps to identify and address new attack vectors and unknown vulnerabilities at an early stage.
• Better decision making: IT teams can make informed decisions by having concrete threat information at their fingertips instead of relying on speculation.
• Increased efficiency: Resources are deployed specifically against the threats that are actually relevant to the company.

How is threat intelligence collected?

The collection of threat intelligence takes place at different levels and can be done by both human and machine sources:

• OSINT (Open Source Intelligence): Information from freely accessible sources such as blogs, news articles, social media and darknet forums.
• Proprietary sources: Private companies offer specialized threat intelligence that comes from exclusive networks or partnerships.
• Malware analyses: Information about new malware is collected through sandboxes and reverse engineering.
• Indicators of compromise (IoCs): Such indicators as suspicious IP addresses or hashes of malicious software often come from post-mortem analyses of cyberattacks.
• Humint (Human Intelligence): Experts and analysts report directly from the areas in which cybercrime is active, such as darknet marketplaces or hacker communities.

What are the different types of threat intelligence?

Threat intelligence can be divided into four main categories:

1. Strategic Threat Intelligence: High-level, long-term analysis that helps executives make business decisions by highlighting trends in cybercrime (e.g. new attack methods or geopolitical risks).
2. Operational threat intelligence: Information about imminent or current attacks, often collected in real time. This helps incident response teams to react quickly to acute threats.
3. Tactical threat intelligence: Focus on specific techniques, tactics and procedures (TTPs) used by attackers. This information is particularly useful for security analysts and systems to detect attacks.
4. Technical threat intelligence: This is about the technical details of threats such as malicious IPs, hash values, domains used for phishing or malware signatures.

How can my company implement threat intelligence?

The implementation of a TI program takes place in several steps:

• Needs assessment: Define which threats are relevant for the company (e.g. industry-specific risks).
• Select data sources: Both internal and external sources can be used. These include commercial providers, but also free data sources such as CERT feeds (Computer Emergency Response Teams) and security blogs.
• Use platforms for automation: Tools such as SIEM (Security Information and Event Management), SOAR (Security Orchestration, Automation, and Response) and specific Threat Intelligence Platforms (TIPs) help to collect, analyze and exploit threat information.
• Train the team: Security managers must understand how to interpret TI data correctly and integrate it into their security strategy.
• Integration into existing security measures: Threat intelligence should be integrated into existing security structures (e.g. firewalls, intrusion detection systems).

What tools and platforms are available for threat intelligence?

There are a variety of tools and platforms that support companies with threat intelligence:

• ThreatConnect: A platform that helps companies manage and operationalize their threat intelligence.
• MISP (Malware Information Sharing Platform): An open source platform for sharing threat data.
• Recorded Future: A commercial tool that analyzes and processes real-time data from various sources.
• Anomali: Another popular threat intelligence tool that focuses on integration with existing security infrastructures.

Many of these tools also offer APIs to connect to existing systems and support the automation of routine tasks.

How do I analyze and use threat intelligence effectively?

The effectiveness of TI depends heavily on the quality of the analysis. Here are some tips:

• Prioritize threats: Not every threat is equally relevant. Filter threats based on your industry and the specific risk profile of your company.
• Add context: Isolated IoCs are often of little value if they are not put into context. Which attacker group is behind the IoCs? What is their motivation?
• Use automation: Use SOAR or SIEM platforms to process threat data in real time and take automated countermeasures.
• Regular updates: Threats are constantly changing. It is important that your TI sources and analyses are updated regularly.

What is the difference between threat intelligence and incident response?

Threat intelligence is proactive and aims to detect and understand threats at an early stage. Incident Response (IR), on the other hand, is reactive and is concerned with responding to security incidents that have already occurred. In other words, TI helps to prevent incidents, while IR ensures that incidents are dealt with quickly and efficiently when they do occur. However, both disciplines work closely together, as TI often forms the basis for effective incident response.

How can threat intelligence help prevent security incidents?

By identifying threats and attack techniques at an early stage, threat intelligence can help to take preventative measures, such as:

• Closing security gaps: If a threat exploits a specific vulnerability, security updates and patches can be applied before the attack occurs.
• Early warning systems: Threat data can be integrated into existing security solutions to block attacks before they reach the network.
• Specific attacker profiles: TI provides information on known attacker groups, enabling targeted measures to neutralize their specific tactics.

What are the challenges of using threat intelligence?

There are various challenges:

• Data overload: There is an enormous amount of threat data. The difficulty lies in separating relevant from irrelevant information.
• False information: Not all TI data is reliable. It is important to assess the quality and source of the information.
• Scalability: Large companies often have difficulties scaling TI data efficiently and making it usable for all relevant departments.
• Cost: Some of the best TI data sources and tools are costly and require significant investment.

What role does artificial intelligence (AI) play in threat intelligence?

Artificial intelligence is playing an increasingly important role in threat intelligence, particularly in the automation of data evaluation and analysis. Some examples of applications are

• Pattern recognition: AI systems can detect unusual behavior patterns and identify potential threats before they become more obvious.
• Predictive models: AI systems can use machine learning to make predictions about future threats based on historical data.
• Automated decision-making: AI can make decisions in real time and initiate immediate countermeasures without the need for human intervention.

How can I ensure that my threat intelligence data is up to date?

The timeliness of the data depends heavily on the sources used. Here are some tips:

• Use real-time feeds: Rely on platforms that provide real-time threat data.
• Check data sources regularly: Ensure that TI platforms and tools used are always up to date.
• Collaboration with information communities: Participate in TI sharing networks such as ISACs (Information Sharing and Analysis Centers) to get the latest information.

What are indicators of a good threat intelligence source?

A good threat intelligence source should have the following characteristics:

• Reliability: The source should provide consistent and verified data.
• Relevance: The data should be tailored to the specific threat profile of your company.
• Timeliness: Threat information becomes outdated quickly. A good source provides data in real time or with very little delay.
• Contextualization: Good sources offer not only raw data (such as IoCs), but also contextual information about the threat.
