With the advancement of information technology, it has become difficult to respond to cyber-attacks against companies using traditional security products alone.Under such circumstances, EDR, which detects abnormalities in devices, is attracting attention.In this article, we will explain the mechanism and functions of EDR, how it differs from antivirus, and EDR investigation to understand virus invasion routes and damage status.
EDR is a security solution that detects and responds to unauthorized activities at endpoints.
EDR stands for Endpoint Detection and Response, and is a security measure that detects unauthorized activity on digital devices such as PCs, smartphones, and servers, and notifies administrators.As work styles change due to the spread of telework, EDR, which strengthens the security of these digital devices called endpoints, is attracting attention.
Differences between EDR and other security products
We will explain the differences between EDR and other security products such as EPP, NGAV, and NDR, as well as the characteristics of each.
Difference between EDR and EPP (antivirus)
EPP is an abbreviation for Endpoint Protection Platform, and is also commonly referred to as antivirus software.It is also used as a security measure for home PCs, and is software that detects and removes viruses. The difference between the two is that EDR's main purpose is to minimize damage after a threat has invaded, whereas EPP's main purpose is to prevent threats before they invade.
Difference between EDR and NGAV (Next Generation Antivirus)
NGAV stands for Next Generation Anti-Virus and is the next generation of EPP.Machine learning technology is used to detect and eliminate abnormalities that have behavior and characteristics similar to malware (malicious software such as viruses).Its feature is that it can handle unknown malware that is not in the database, but it differs from EDR in that, like EPP, its main purpose is to prevent threats before they infiltrate.
Difference between EDR and NDR
NDR is an abbreviation for Network Detection and Response, and is a security measure that detects and responds to unauthorized activities on a network. The difference is that while EDR is a measure for endpoints, that is, devices such as PCs and servers, NDR is a measure for networks, that is, the movement of communication after an intrusion.
The importance of EDR in cybersecurity and the reasons why EDR is receiving increasing attention
We will explain the importance of EDR, which approaches threats that cannot be prevented, rather than preventing the intrusion of threats, and the background why it is attracting attention.
Increasing sophistication and sophistication of cyber attacks
As technology evolves, cyber attacks are also becoming more sophisticated and sophisticated.Even if security measures are taken, it is almost impossible to completely prevent intrusions because more attacks will occur soon.For this reason, EDR, which is a mechanism to minimize damage in the event of an intrusion, is gaining importance.
Popularization of mobile devices
The spread of mobile devices such as smartphones and tablets is also having an impact.Cases of intrusion into corporate servers via employees' smartphones and cases of intrusion using Wi-Fi environments in cities are increasing, making it difficult for traditional security systems to respond.
Diversification of work styles such as telework
Diversification of work styles due to the coronavirus pandemic is also one of the factors.With the spread of remote work, there are more opportunities to conduct work from home or outside the office on networks outside the company, and attack vectors have also become more diverse.In such a network environment, there are limits to perimeter defenses that separate the inside and outside of the company, so it is necessary to strengthen endpoint security in accordance with the zero trust concept of "not trusting unconditionally."
Points to consider when considering EDR products
There are a wide variety of EDR products, and each product has different features and costs, so it is important to choose a product that suits your company's security situation.In addition, there are cases where tools that are popular as EPP also provide EDR, but the EDR function of some of these products seems to be somewhat insufficient.If you are in a situation where full-fledged EDR functionality is required, the key is to choose a product that suits your company's circumstances and objectives, such as choosing a product that has EDR functionality as its main feature.
Target of EDR investigation and what can be learned from the investigation
We will explain what EDR investigates and what can be learned as a result.
Virus entry route
When EDR investigations detect suspicious behavior or suspicious programs, you can catch up on lateral movement from the active endpoint (device) that is the origin of the breach.Additionally, if you have introduced an EDR license that retains logs for a certain period of time in the past from normal times, it will be possible to identify the intrusion route by analyzing the process going back from the time of detection.
Damage situation
EDR investigations collect and analyze information such as the type of malware detected, its intrusion route, and whether information has been leaked, allowing us to identify the root cause of security breaches and visualize the damage situation.
FRONTEO's "Cyber Security Investigation Package" is used to respond to cyber attack damage, including EDR investigations.
Although EDR has many advantages, there are also some disadvantages.One is that it is costly to implement.The other is the need to allocate resources to operations.It is necessary to secure human resources with the knowledge and experience to respond when a threat occurs, and to establish an operational system that can respond promptly.
To eliminate these disadvantages, we recommend FRONTEO's "Cyber Security Research Package." FRONTEO, which boasts a track record of over 10,600 fraud investigations, provides high-quality cybersecurity investigations that are recommended by multiple insurance companies. Surveys can be conducted from a single PC.
We provide not only EDR investigation but also dark web investigation in one package. Additional investigations such as Wi-Fi vulnerability investigations, NDR investigations, and penetration tests can also be conducted.For companies that do not have human resources with specialized knowledge, there are concerns about the speed and professionalism with which they respond to emergencies.Based on the know-how gained from our overwhelming track record, FRONTEO supports the initial response to cyber attack damage.
