What Is Threat Intelligence in Cyber Security?
In the world of cyber security, there is a term that you may have heard bandied about but aren’t quite sure what it means: threat intelligence.
What is threat intelligence, and why do you need it for your business?
In this article, we will explore the concept of threat intelligence and how it can be used to improve your business’s cyber security posture. We will also touch on some of the different types of threat intelligence and how they can be used in your organization.
What is threat intelligence?
Threat intelligence (TI) is data that’s collected and analyzed to understand current and future risks to an organization. It can take many forms, but it’s typically used to give security teams a better understanding of the attacks they’re facing, the attackers themselves, and how to protect against them.
Organizations use threat intelligence in several ways. Some use it to inform their overall security strategy, while others use it more tactically, for example, to choose which security products to deploy or which vulnerabilities to patch first. TI can also be used to help investigate and respond to incidents.
There are different types of threat intelligence, but one common distinction is between internal and external TI. Internal TI is information that’s gathered by an organization itself, while external TI is information that’s sourced from outside the organization. External TI can come from a variety of sources, including commercial vendors, government agencies, and open-source projects.
Regardless of where it comes from, all threat intelligence should be evaluated for quality before it’s used. This includes considering things like who collected the data, what methods were used, how complete and accurate the data is, and whether or not it’s timely. Poor-quality threat intelligence can do more harm than good by leading organizations to make bad decisions based on inaccurate or out-of-date information.
The benefits of threat intelligence
Threat intelligence (TI) is simply information about threats. It helps organizations identify, assess, and understand current and future risks. In cybersecurity, analysts use TI to improve their organization’s security posture by informing decisions about everything from technology investments to business processes.
There are many benefits of using threat intelligence, including:
-Improved security: By understanding the threats faced by an organization, analysts can make better decisions about which security controls to implement. This can lead to a more effective and efficient security program overall.
-Reduced costs: An organization that understands the threats it faces can make more informed decisions about where to allocate its resources. This can lead to reduced costs associated with things like incident response and malware removal.
-Greater efficiency: A well-run threat intelligence program can help an organization save time and effort by providing analysts with actionable information that they can use to immediately address risks.
-Improved decision-making: Threat intelligence can help senior leaders make better decisions about strategic issues like corporate risk tolerance and resource allocation.
TI provides organizations with a wealth of benefits that can help them improve their security posture and become more efficient and effective overall.
How to use threat intelligence
If you want to know how to use threat intelligence, you must first understand what it is. Threat intelligence is simply information that helps organizations and individuals identify, assess, and respond to current and future cyber threats. This information can come from a variety of sources, including social media, news reports, dark web forums, and more.
To effectively use threat intelligence, you need to have a plan in place for how you will collect and analyze this information. You also need to make sure that your team is trained on how to interpret and act on the information you collect.
Once you have a plan in place and your team is trained, you can start collecting threat intelligence. There are several ways to do this, but some of the most common include using search engines, setting up Google Alerts, subscribing to RSS feeds, and monitoring social media platforms.
Once you have collected some threat intelligence, it's time to start analyzing it. This can be done manually or with the help of special software tools. Either way, you need to look for patterns and trends in the data so that you can better understand the threats you're facing.
After you've analyzed your threat intelligence, it's time to take action. This will vary depending on the type of threats you're facing and the severity of those threats. In some cases, taking action may mean alerting your team or customers about a potential danger. In other cases, it may mean taking steps to prevent them.
The different types of threat intelligence
There are four different types of threat intelligence:
1. Strategic intelligence: This type of intelligence helps organizations make long-term decisions about their cybersecurity strategies. It can help you understand the motivations and goals of your adversaries, as well as their capabilities and vulnerabilities.
2. Tactical intelligence: This type of intelligence is designed to help organizations respond to specific security incidents. It can provide information about the techniques and tools that your adversaries are using, as well as their likely next steps.
3. Technical Intelligence: This type of intelligence focuses on the technical details of security threats. It can help you understand how your adversaries are exploiting vulnerabilities, as well as the methods they're using to evade detection.
4. Open-source intelligence: This type of intelligence is derived from publicly available information, such as news reports, social media posts, and blog articles. It can be used to supplement other types of intelligence, or it can be used on its own to give you a broader picture of the security landscape.
Tools for gathering threat intelligence
There are several tools available for gathering threat intelligence. Some of these tools are designed specifically for gathering intelligence, while others are more general-purpose tools that can be used for a variety of purposes, including gathering intelligence.
One popular tool for gathering intelligence is the Security Information and Event Management (SIEM) system. SIEM systems collect data from a variety of sources and provide users with a central place to view and analyze that data. SIEM systems can be used to detect threats, track changes in network activity, and more.
Another popular tool for gathering intelligence is the intrusion detection system (IDS). IDSs monitor network traffic and look for signs of suspicious or malicious activity. IDSs can generate a lot of data, so they must be configured carefully to avoid generating false positives (alerts on activity that is not suspicious or malicious).
Threat intelligence can also be gathered manually by analysts who review data from various sources and try to identify potential threats. This approach can be time-consuming, but it can also be very effective in identifying emerging threats that might not be detectable using automated tools.
Cyber security threats to be aware of
When it comes to cyber security, there are several different threats that you need to be aware of. Here are some of the most common cyber security threats:
1. Malware: This is a type of software that is designed to damage or disable computers. It can come from viruses, Trojans, worms, and more.
2. Phishing: This is a type of online scam where criminals try to trick you into revealing personal information or clicking on malicious links.
3. SQL Injection: This is a type of attack where malicious code is injected into a database to steal data or damage the system.
4. Denial of Service (DoS): This is a type of attack where a computer system is overloaded with traffic or requests, causing it to crash or become unavailable.
5. Social Engineering: This is a type of attack where criminals use psychological techniques to trick people into revealing personal information or performing actions that could compromise security.
Threat intelligence is a critical component of any cybersecurity strategy. By understanding the latest threats and trends, businesses can take proactive steps to protect themselves. While threat intelligence can be complex, there are several resources available to help businesses get started. With the right tools and strategies in place, businesses can stay one step ahead of the attackers.
