The professionalism of MDR vendors in threat intelligence determines the depth and breadth of MDR services.
MDR vendors with rich threat intelligence are like intelligence scouts who have information about their opponents on the field. They use this intelligence to
Construct a wider defensive range, master the opponent's offensive, and effectively counterattack.
What is threat intelligence? Why is it important?
Threat intelligence refers to information related to network attacks. It needs to be collected, converted, analyzed, interpreted, etc. by a professional team before it can be transformed into useful intelligence. This is also the cybersecurity decision-making process. the required foundation.
Threat intelligence is divided into three levels according to its connotation, and each level can bring benefits to the enterprise's cybersecurity plan.
1. Tactical threat intelligence
It refers to the intrusion indicators (IoC) used to monitor specific attack events, such as: IP/domain blacklist imported by the cybersecurity team into the enterprise security equipment, etc.
2. Operational threat intelligence
Refers to information that can understand the attacker's tactics. If cybersecurity teams have a good grasp of attack techniques, they can track, identify and neutralize attacks. In particular, understanding the attacker's strategy can greatly help the cybersecurity team detect attacks early and nip them in the bud at the initial stage.
3. Strategic threat intelligence
This intelligence is used to identify who might attack and why. The threat intelligence professional team analyzes the attack methods commonly used by different hacker groups (also known as attack groups) to identify the organizations launching the attacks and understand the purpose of the attacks.
Based on this kind of information, the cybersecurity team can grasp the current situation of the enemy, predict the development trend of threats, and adjust the cybersecurity deployment in advance to achieve the effect of defeating the enemy.
How is threat intelligence used in MDR services?
Network attacks can be broken down into three major stages, including "before the invasion", "during the invasion", and "after the invasion".
In general MDR services, before an enterprise encounters an intrusion, the vendor will assist the enterprise in deploying an environmental monitoring mechanism and introducing security equipment.
When an attacker has begun to try to intrude, MDR vendors monitor behavioral events within the endpoint and immediately issue alerts for abnormal behavior.
After an intrusion, MDR vendors use threat hunting to clarify the entire incident, trace the root cause, and provide correct handling suggestions. They can also assist companies in adjusting their security policies and regulations.
However, MDR vendors that effectively master threat intelligence can provide more accurate and effective services in addition to original attack defense.
Specifically, MDR vendors who have mastered threat intelligence can monitor the dark web and pay attention to the trends of malicious groups before intrusion, and can predict possible attack targets in the near future or precursors of attacks. For example, it is discovered on the dark web that someone is purchasing and collecting login credentials of a specific enterprise; MDR vendors can also use the content of threat intelligence to arrange the order of importance of enterprise assets, patch important targets in advance, and allocate resources to where they are needed first. A place of protection.
In the early stages of an intrusion incident, MDR vendors who have mastered threat information are already familiar with the attack methods of hacker groups, or have developed effective detection indicators based on threat intelligence, which can help enterprises identify abnormal behaviors in the early stages of an incident and prevent or activate them. Strain mechanism.
After an intrusion event, MDR vendors can combine threat intelligence and threat hunting skills to deeply trace the clues within the host to achieve a defense-in-depth effect.
Threat intelligence plays an important role in the MDR service process. MDR vendors that directly grasp and effectively use threat information provide better service quality. Therefore, the MDR vendor's professionalism in threat information determines the depth and breadth of its services.
