Microsoft Defender for Endpoint: 6 key features and weaknesses

What is Microsoft Defender for Endpoint

Microsoft Defender for Endpoint is one of the most important tools of Microsoft 365 Defender, the solution designed to defend a company's IT infrastructure and digital workplace. Defender for Endpoint specializes in the protection of laptops, PCs, servers and mobile devices, that is, the points of access to business data. His task is therefore to monitor them in a proactive, intelligent and coordinated way with the activities of all the services that accompany him on the platform.

Microsoft Defender for Endpoint aims to:

• Preventive protection.
• Post-violation detection.
• The proactive and unified response across endpoints.

His intervention therefore translates into a significant reduction in exposure to threats, as well as in the impact that incidents can have on the corporate security system. But it's important to stress the way in which these results are achieved. In fact, Defender for Endpoint follows a precise course of action, based on:

• Artificial intelligence and machine learning.
  
• The behavioral analysis of endpoints.
  
• Real-time monitoring.
  
• The automated response.
  

Starting from the first point, Defender for Endpoint makes use of AI to identify tools, techniques, and procedures in business endpoints. He then compares them with the behavioral patterns he has learned over time to recognize abnormal activities and trace them back to malicious users. It then analyzes the threats and sends the reports with the relevant information in a sandbox. Here, the Threat Investigation is carried out to trace the attack chain and view forensic data on the attacks identified.

Finally, the system isolates the compromised endpoint to eradicate the current threat and restore its security state. It is a complete and effective intervention, which simultaneously and constantly involves the different endpoints of a company.

The 6 key features of Microsoft Defender for Endpoint

Along with the other products on the platform of Microsoft 365 Defender, Defender for Endpoint guarantees the complete, intelligent and proactive protection of corporate data and identities. Here are the features that allow it to contribute to this holistic protection system, starting with the endpoints.

1. Threat and Vulnerability Management: The system identifies and protects endpoints from attacks based on the vulnerabilities of each operating system and individual applications. It can mitigate these specific threats thanks to continuous updates released by Microsoft and its machine learning and threat intelligence capabilities.
   ‍
2. Reduction of the attack surface: Provides the infrastructure's first line of defense with capabilities that are resistant to attacks and exploits. These include specific network and web protection sets that regulate access to potentially harmful IP addresses, domains, and URLs.
   ‍
3. Next-generation protection: Uses machine learning algorithms and artificial intelligence models to detect abnormal behavior and identify all types of emerging threats.
   ‍
4. Endpoint Detection and Response: It provides detailed information on the endpoints, regarding the apps installed, the processes that are running and the network events that characterize them. The advanced system detection also offers a proactive and customizable query-based threat search tool.
   ‍
5. Auto Investigation and Remediation: It allows you to automate incident response, as well as the isolation of compromised endpoints, the blocking of ongoing attacks and the removal of threats.
   ‍
6. Microsoft Threat Experts: The new threat detection service managed by Microsoft Defender for Endpoint provides proactive research, prioritization, and additional context and information to support Security Operations Centers (SOC) in identifying and responding to threats quickly and accurately.

The weaknesses of Microsoft Defender for Endpoint, and how to fix them

We've come to the final part of our overview of Microsoft Defender for Endpoint. We conclude with some points of attention and best practices useful for those who have never used this or other services of Microsoft 365 Defender.

• Zero-day exploits: Zero-day exploits are unknown security vulnerabilities that are commonly difficult to prevent. Even if the machine learning and threat intelligence capabilities make Defender for Endpoint rather secure against these vulnerabilities, it is good to always keep the system updated to mitigate the risk.
  ‍
• False positives: Defender for Endpoint may occasionally generate false positives, i.e. recognize as threats files and activities that are instead legitimate. To avoid the problem, you must carefully configure the detection rules and monitor their logs frequently.
  ‍
• Internet connection addiction: Some Defender for Endpoint features require an internet connection to activate. For example, sending alerts in real time or accessing the most recent threat definitions. The simplest (and perhaps the only feasible) solution is to integrate external offline security measures into the system.
  ‍
• Managing configurations: As with the entire Microsoft 365 Defender ecosystem, it is necessary to correctly configure the service configurations to avoid a reduction in performance or, on the contrary, an increase in exposure to attacks and threats. To do this, you can follow the guidelines indicated by Microsoft in its documentation.
  ‍

The best choice, however, remains to rely on people who are experts in the sector or specialized consultants.
