What is Threat Intelligence and Why Is It Important?

Threat intelligence in cybersecurity describes information that helps organizations understand cyber threats. This information enables them to identify and prepare for risks that could affect their systems and data. This information describes who might attack, how they attack, and what damage they can cause to the organization. Understanding these aspects helps organizations develop better defences, prevent attacks before they occur, and select a response in the event of an attack.

Why is Threat Intelligence Important?

The top reasons are:

1. Early Warning Indicators: It allows for the detection of threats before they impact an organization, so that organizations can respond to the threats.
2. Informed Decision Making: Teams can prioritize what to protect and where to focus their security issues.
3. Insights into Attackers: Threat intelligence describes who the attackers are, the tools they use.
4. A Defence System: Intelligence provides updated and relevant threat information for firewalls, antivirus, and other protective tools to create a better defence mechanism.
5. Cost-Effective: It is much cheaper to prevent an attack than to deal with a successful attack.
6. Protect Your Reputation: The failure to address cyber incidents can reduce trust from customers and partners in business situations.

Types of Threat Intelligence

1. Tactical Threat Intelligence: This provides information on the technical indicators of a threat. For example, it may include details on malware, IP addresses, or unusual login attempts. Security teams use this information to detect and block attacks as they occur.
2. Operational Threat Intelligence: This will include details of specific attacks or campaigns. It will help teams learn about the attackers, including their methods, targets, and timing. This helps create a defensive plan for your organization and schedule the work to investigate the ongoing security incident.
3. Strategic Threat Intelligence: This type of intelligence is designed for decision-makers, such as executives and other leadership roles. This intelligence is useful in guiding business decisions for security investments.

Benefits of Threat Intelligence

Threat intelligence has many benefits. It helps organizations improve security and minimize risks. Let’s take a look at a few types of organizations and how they profit from threat intelligence.

1. Small and Medium-sized Businesses (SMBs)

• Affordable, Better Security: SMBs don’t have large security teams, and threat intelligence helps focus on the threats that matter most.
• Faster Attack Detection: It allows SMBs to quickly detect when they are under attack and prevent damage.
• Improved Confidence: An understanding of the threat improves an SMB’s confidence in its defences.

2. Enterprises

• Building a Comprehensive Defence: Threat intelligence helps a large company to handle and prevent complex threats.
• Strategic Planning: Threat intelligence can help an enterprise in making long-term security plans.
• Better Use of Resources: It can help organizations prioritize efforts and resources in a way that ensures security activities are used toward the threats that matter.

How Threat Intelligence Benefits a Specific Role

Sources of Cyber Threat Intelligence

1. Open Source Intelligence: This comes from publicly published information. There is a plethora of blogs, news sites, social media, and online forums where cybersecurity practitioners are posting information regarding new threats and hacker techniques. This is also a very valuable piece of the puzzle in identifying the newest cyber threats.

2. Internal Intelligence Data: Organizations collect security data, often from a mixture of their firewalls, anti-virus, proxies, systems logs, etc. This data helps the organization to spot abnormal data patterns that are different from normal activity, which means a hacker might be attempting an attack using data from within their organization or from outside.

3. Commercial Threat Intelligence Feeds: These are the products connected to a subscription model from cybersecurity companies. They provide time-sensitive materials on known threat information, including viruses, phishing sites, hacker IP addresses, etc, as relevant content in a business that tries to leverage its threat detection and responses.

4. Government Agencies and Occupation Sharing Groups: There are several government agencies and trade professions that provide threat-related information as a service for members of their respective groups.

Threat Intelligence Platforms

Threat Intelligence Platforms (TIPs) are tools designed to allow threat intelligence to be collected, processed, and analyzed in a better way. Instead of doing it as a manual task or struggling to manage the huge amount of data on its own, a TIP allows the data to be organized and automated in ways that let the security teams focus on real threats.

Capabilities of Threat Intelligence Platforms:

1. Collect Data from summarized sources: Threat Intelligence Platforms ingest threat data from open sources, commercial threat intel feeds, internal data, and government alerts, and summarize all of this into an easy-to-digest source.
2. Delete duplicates and unusable data: A big part of being efficient is using clean and structured data and deleting duplicates. This can clean the data in a structured output.
3. Analyze Threats: Using Threat Intelligence Platforms, security teams can take the complex data set and find patterns, correlate threats, and learn what they need to be on the lookout for.
4. Share Intel quickly: Threat Intelligence Platforms allow the teams to share specific threat intel easily and securely with the rest of the organization or with partners.
5. Integrate with other Security Tools: Threat Intelligence Platforms can be used to improve defence and firewalls, SIEM (security information and event management), and antivirus software.

Why Threat Intelligence Platforms are Helpful?

1. Cut time gaining insights from threat data.
2. Make more decisive actions with succinct and reliable threat insights.
3. Improve team collaboration, with better and faster threat reaction.
4. Decrease missing critical warning signs.

Threat Intelligence Lifecycle

Threat intelligence is not a singular process, but a continuous cycle that needs to change with each iterative threat. This cycle enables organizations to take effective steps to acquire the right information, understand each attack, and use it better to protect organizations. Each step is necessary in the cycle from taking raw data to informing actionable intelligence.

1. Requirements: Understanding what type of threat intelligence is needed, depending on the industry you work in, the job you do, or specific matters you are dealing with (i.e., phishing attacks, ransomware, insider threats).

2. Collection: Collecting information or intelligence from a variety of data sources, depending on the requirements, could include internal logs, open-source feeds, available commercial services, or government alerts.

3. Processing: Once you have collected your data, it needs to be processed properly. This makes it easier for analysts to review and draw meaningful insights from it. This means cleaning, sorting, and organizing each source of intelligence data, which includes removing duplicate examples and filtering unrelated information.

4. Analysis: Analyze the processed data for patterns and threats. You want to use this data to derive insights that help decision-makers understand the risks involved.

5. Dissemination: Deliver insights to the relevant people, whether it is security teams, executives, or different departments, and do it on time so that the information can be used quickly.

6. Feedback: Collect feedback on the process from people who utilized the intelligence, considering the potential, discussing what worked, what did not work, and how the process can be improved in the next round.

Threat Intelligence Use Cases

1. Identifying Phishing Attempts: Assisting in the identification of phishing emails and website attacks where the attackers impersonate legitimate processes to use sensitive information.

2. Preventing Malware: Notifying an organization about the early detection of known malware indicators, along with their potential points of entry, allows for proactive defence. This gives organizations the ability to block threats before they cause any harm.

3. Monitoring Threat Actors and Groups: Understanding cybercriminals, such as hacking groups, and their behaviour, is crucial. It involves knowing who might be motivated to attack an organization and the methods they are likely to use.

4. Protecting Critical Infrastructure: Protecting identity and critical systems such as the power grid, hospitals, and financial networks, while knowing what threats are specifically posed to those systems.

Common Cyber Threats and Their Motivations

Here are some of the most common types of cyber threats:

• Malware: Malware is bad software made to harm computers, steal data, or control systems. Most attackers use it to make money or create problems for others.
• Phishing: Phishing tricks people into giving away important details like passwords or bank information. The goal is to steal money or use someone’s identity.
• Ransomware: Ransomware locks important files and asks for payment to unlock them. Attackers do this to earn quick money from users or companies.
• Insider Threats: These come from people inside a company who misuse their access. They may do this for personal benefit, anger, or by mistake.
• Advanced Persistent Threats (APTs): APTs are slow, planned attacks by skilled hackers. The goal is often to steal data or spy on organizations for a long time.

Challenges in Implementing Threat Intelligence

Implementing threat intelligence effectively comes with several challenges that can limit its impact and delay threat detection.

• Data Overload: Handling large volumes of raw data can make it difficult to identify real threats.
• False Positives: Legitimate activities may be incorrectly flagged as security threats.
• Skill Gaps: There is often a shortage of professionals with expertise to analyze and apply threat intelligence effectively.
• Integration Issues: Incorporating threat intelligence into existing security tools and workflows can be complicated.
• High Costs: Advanced threat intelligence services may involve significant expenses, especially for smaller organizations.

Conclusion

Threat intelligence is a critical component of modern cybersecurity. It helps organizations of all sizes to educate themselves about cyber threats and respond to them. The difficulties of threat intelligence can be overcome. When organizations use the right types of intelligence, sources, and tools for different types of cybersecurity attacks, they can reduce their risk and be more agile when responding to an attack. Building out a threat intelligence program takes time and effort, but in the end, organizations are better protected.
