For those who are still unfamiliar with Microsoft Defender, you should know that this is a unified platform for preventive protection, theft detection, automated review and response. Microsoft Defender ATP protects endpoints from cybercriminals, detects advanced attacks and data breaches, automates security incidents, and improves security.

It serves as an infrastructure to reduce the organization's exposure, strengthen the endpoint surface, and increase the organization's resilience.

Allows organizations to detect vulnerabilities and incomplete configurations in real time, sensor-based, without requiring an agent or periodic scanning. It prioritizes vulnerabilities based on the threat landscape, threats detected within your organization, sensitive information on vulnerable devices, and your work environment.

According to Microsoft, Defending ATP helps reduce the attack surface by reducing the places where it is vulnerable to cyber threats and attacks. Microsoft provides administrators with a set of resources to configure protection for their organization's devices and applications.

Application control can help limit these types of security threats by restricting the applications that users can run and the code that runs in the core of the system. Application control policies can also block unsigned MSI and scripts and limit Windows PowerShell to run in restricted language mode.

While controlled access to folders to protect important data from malicious applications and other threats such as ransomware. This feature protects your data by searching a list of known and approved applications.

These features allow advanced attacks to be detected in near real time. Security analysts can effectively prioritize alerts, gain visibility into all breaches, and take action to address threats.

When a threat is detected, alerts are created in the system for an analyst to examine. Alerts associated with the same attack techniques or assigned to the same attacker are aggregated into an entity called an incident.

    What is Microsoft Defender for? I have never used it on Windows. I don't see what use it can have in Linux.

    Does it mean that Windows already uses its own products in critical processes to be pretended to be better than Linux?
