Decoding Cyber Threat Intelligence
What is Cyber Threat Intelligence?
Cyber threat intelligence is a flexible, dynamic technology that uses data gleaned from threat history to block and remediate cyberattacks on the target network. The threat intelligence itself is not a hardware-based solution. Rather, it is a crucial component of an organization’s overall security architecture. Because threats evolve and multiply over time, a cybersecurity system depends on threat intelligence to ensure it catches as many attacks as possible.
With threat intelligence, you gain knowledge, which empowers you to prevent or mitigate attacks on your network. The cyber threat intelligence system is based on hard, actionable data, such as 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 extend beyond the IT team and administrators. The entire organization can reap the rewards of a thorough and action-focused cyber threat intelligence system.
The Need for Threat Intelligence?
Cybersecurity tools are nearly powerless if they are not told which threats to watch out for and how to mitigate them. Cyber threat intelligence provides cybersecurity system administrators with the knowledge they need to formulate a plan that will best protect their network. In some situations, elements of the data gained by devices to empower cyber threat intelligence can be used to attack threats automatically. In other situations, cyber threat intelligence is a necessary tool for network administrators and IT teams to know which threats are the most dangerous, how they attack, and how to prevent them.
With an investment in cyber threat intelligence, a business can avail itself of threat databases that detail a vast number of threats. When this storehouse of knowledge is put to work by the security team or the automated systems used to protect the network, the business’ safety profile is significantly enhanced.
Common Indicators of Compromise (IOCs)
Often, a cyber threat intelligence system may pick up a suspicious Internet Protocol (IP) address, Uniform Resource Locator (URL), or domain name that is known for being used in attacks on businesses. If an endpoint has interacted with one of these, that may mean the company’s network has been compromised. Further, accessing specific email addresses, certain email subjects, or attachments and links can indicate the system has been compromised.
Certain filenames, file hashes, dynamic link libraries (DLLs), or registry keys are common IOCs. A cybersecurity system can maintain a list of these and other tools that threat actors use and filter out potentially dangerous communications and other network activity.
Data vs. Intelligence
An effective cybersecurity system makes a clear distinction between data and intelligence. Cyber threat intelligence collects and processes data to detect, stop, and mitigate threats. Data, on its own, is useless until it is analyzed. The analysis reveals information such as the types of threats that may be imminent, weaknesses in the network, and where threats come from. This is collated and implemented into a cyber threat intelligence system.
In other words, data is one of the building blocks of cyber threat intelligence. Cyber intelligence security professionals, given the right tools, can use threat data feeds and information regarding the network and business to formulate a more complete protection plan for the organization.
Who Benefits from Threat Intelligence?
Threat intelligence provides benefits to organizations big and small—and across a wide range of disciplines—because it involves processing data and using it to gain a stronger understanding of the attackers an organization is facing or may face. Threat intelligence also enables the organization to formulate quick, decisive responses to incidents and be proactive regarding how to remain one step ahead of attackers.
When it comes to small to midsize businesses (SMBs), threat intelligence provides protection that may be otherwise unattainable because it avails them of a vast storehouse of the threats that may attack their network. Large enterprises, on the other hand, can use the information from the cyber intelligence system to better analyze the bad actors, their tools, and how they attempt to use them.
- A security/information technology analyst can use cyber threat intelligence to better prevent and detect threats.
- A security operations center (SOC) can leverage threat intelligence to decide which incidents they must devote their attention to using data regarding the level of risk and how they may affect the organization.
- An intel analyst benefits from cybersecurity threat intelligence because they can use it to find and keep track of bad actors going after the organization.
- Executive management can rely on cyber threat intelligence to gain a better understanding of the risks faced by the company, their impact on operations, and how to deal with them.
Is My Organization Equipped for Threat Intelligence?
Your organization is equipped for threat intelligence if you have the following elements in place:
- The ability to detect threats
- A system for collecting threat data
- A method for analyzing the data for use against existing threats and similar types of attacks that may appear in the future
- A mechanism for applying the knowledge gained from the analysis. This is where threat intelligence transitions from conceptual to actionable.
3 Ways To Deliver Threat Intelligence
The format and presentation of the threat intelligence that ends up being disseminated depends on the audience, the intelligence requirements, and where the information comes from. To simplify the delivery process, there are three categories of threat intelligence: strategic, tactical, and operational.
Strategic Threat Intelligence
Strategic threat intelligence gives stakeholders a bird’s eye view of the organization's threat landscape. This helps those in the audience, such as executives and key decision-makers, to make high-level decisions as to how to use the information. Strategic threat intelligence may use internal policy documents, news reports, white papers, or other research material provided by security organizations.
Tactical Threat Intelligence
Tactical threat intelligence defines bad actors' techniques and procedures. It is intended to help defenders understand how the organization could be attacked and how to defend against or mitigate those attacks.
Operational Threat Intelligence
Operational threat intelligence involves presenting knowledge regarding cyberattacks, whether they are singular events or long-term campaigns. Operational threat intelligence gives stakeholders insights that can be used by incident response teams to better comprehend attack elements, such as their timing, purpose, and how they are carried out.
What to Look for in a Threat Intelligence Solution
Although threat intelligence is a necessary element of any cybersecurity approach, make sure the system you implement is adequate for your needs. Regardless of the size or nature of your organization, there are a few components of a threat intelligence solution you will need to have in place.
Simplified Access To Diverse Data
The more data the better, as each data point in a threat history dataset can be used to defend against a bad actor. Therefore, the more you have, the stronger your defenses will be. You will also need threat intelligence that incorporates machine learning capabilities because this directly impacts the size and quantity of your datasets.
Machine learning has the ability to recognize patterns and use these to predict threats before they hit your network. Those in charge of IT security can leverage machine learning-generated datasets to detect and then evaluate a wide array of dangers, including advanced persistent threats (APTs), malware, ransomware, and zero-day threats.
A cyber threat intelligence program must incorporate automated responses to threats. Automation can serve several purposes.
Automating threat data detection and collection relieves IT teams of responsibilities involving targeting and logging every threat that engages the attack surface. Moreover, when cyber intelligence incorporates automated action steps once a threat has been identified, the network and its connected devices are better protected.
While some threat behavior analysis is best done using human problem-solving and creative thinking, threats can be automatically contained and eliminated by the system. You can also automate measures to shield the rest of the network from the threat, such as malware analysis within a sandboxed environment.
While nothing can—or should—eliminate the competitive element within each industry vertical, in many ways, cyber threat security is a team effort. A comprehensive cyber threat intelligence solution incorporates insights from various professionals and organizations within your industry, as well as within the cyber threat intelligence community.
Information regarding the types of landscape threats and how they behave can be shared, and a cyber threat intelligence program should incorporate this crucial information. Also, some threats are more likely to impact some industries than others. Therefore, within your specific industry, there should be information concerning the latest attacks, the malicious actors and software responsible, and how they have been defeated in the past.
A cyber threat intelligence professional may also have access to data regarding how these threats have impacted similar businesses, including how much downtime has resulted from a successful attack and the financial impact on the organization.
The speed at which a cyber threat intelligence program reacts to threats is a crucial factor in its success. A matter of minutes can make the difference between an expensive attack and a minor disturbance. With a fast response, a threat can be detected and analyzed. Data regarding its behavior can be quickly put to work to prevent the next attack.
However, speed should not be used as an excuse to justify poor performance. A fast response also has to be an accurate one. Therefore, an adequate cyber threat intelligence system can filter out false alarms and identify threats with a lower likelihood of causing significant damage.
Ease of Integration
Integrating a cyber threat intelligence system should be simple and easy to execute. While meeting the needs of each organization certainly takes time and careful thought, the cybersecurity infrastructure should integrate well with your network.
Ideally, all cyber threat intelligence data should be accessible via a single dashboard. If the dashboard is customizable, administrators can dictate who has access to what. Integration is also easier if the threat intelligence system is ready, out of the box, with infrastructure that enables it to cover common devices, making it a valuable tool virtually right away.
The Value of Comprehensive Cyber Threat Intelligence
The primary benefit of a comprehensive cyber threat intelligence program is it ensures the organization is prepared and proactive. Threat intelligence allows an organization to access a storehouse of technical information gathered from around the world, as well as human knowledge that can significantly strengthen an organization’s defenses.
This is accomplished through an adversary-focused approach that identifies the threats most likely to compromise the network and its individual components. It can also be customized based on an organization’s needs. Further, cyber threat intelligence can be scaled up if the company grows or needs to expand the types of threats it targets.
The different components of a threat intelligence program result in better incident response times. As alerts are prioritized, the organization can respond in less time and lower the risk of a major fallout from a breach. Also, in the end, threat intelligence enhances communication between the IT team and stakeholders, while providing a window into the threat landscape for those who may not be familiar with the nitty-gritty of cybersecurity.
What Organizations are Getting Wrong about Cyber Threat Intelligence
Understanding the Value to their Business
Even though threat intelligence focuses on important business problems, it is easy for decision-makers to underestimate its value. This is often due not to a lack of comprehension on the part of stakeholders but insufficient explanation and presentation on the part of the cybersecurity team. A cyber threat analysis presentation can easily devolve into a showy and confusing display of graphics and statistics, losing its teeth along the way.
To prevent this kind of misunderstanding, it is crucial for the threat analysis team to outline the specific business problems that arise due to the threats described during the dissemination phase. Also, action steps should be detailed, including how they may benefit the business’s bottom line.
The Wrong Feed
Because there are so many feeds to choose from in a threat analysis system, it can be easy to pick one that is not relevant to your business. It is important to identify the best feed for your operation. This is often similar to the feed other businesses in your sector and of similar size use, but your infrastructure or products and services may sometimes require a different feed than very similar businesses.
Also, keep in mind that if your attack surface includes the personal data of specific executives or others in your company, a different feed may be necessary than if you were only trying to protect your digital assets, for instance. There are many factors that will determine how you choose your feed, but with careful planning, you can make the right choice.
