How to increase the level of security in Microsoft 365?<\/h2>\n\n
\n

To increase the level of security in Microsoft 365, administrators should enable multi-factor authentication, configure Conditional Access, use Advanced Threat Protection, and regularly review the Secure Score value. Security policies, activity logs, and user training complement the technical measures and reduce the risk of phishing, ransomware, and unauthorized access. <\/p>\n <\/div>\n\n

\n

Background and overview<\/h2>\n

The level of security in Microsoft 365 depends on configuration, policies, and user behavior. With the right settings, organizations can protect data, communications, and user accounts against modern threats. <\/p>\n\n

Enable multi-factor authentication (MFA)<\/h3>\n

MFA requires multiple confirmations at login, which prevents unauthorized access even if passwords are leaked.<\/p>\n\n

Use Conditional Access<\/h3>\n

Conditional Access allows administrators to define access rules based on location, device or risk level, increasing control over user accounts.<\/p>\n\n

Implementing Advanced Threat Protection (ATP)<\/h3>\n

ATP protects against malicious links and attachments, identifies phishing attempts and blocks malicious messages before they reach users.<\/p>\n\n

Review and improve Secure Score<\/h3>\n

The Secure Score provides an overview of the security status and recommends measures to increase the level of protection.<\/p>\n\n

Monitor with activity logs<\/h3>\n

Through regular analysis of activity logs, unusual behavior and security incidents can be detected in time.<\/p>\n\n

Update policies and access rights<\/h3>\n

Ensure that users only have the necessary rights and that internal security policies are followed to minimize the risk of unauthorized access.<\/p>\n\n

Training users<\/h3>\n

User training on phishing, social engineering and security practices is essential to complement the technical protection measures.<\/p>\n <\/div>\n\n

    What is Conditional Access?<\/h3>\n

    A system to control access based on the user’s location, device or risk level.<\/p>\n <\/div>\n\n

    \n

    How often should security be reviewed?<\/h3>\n

    Regular review is recommended, especially in case of changes in the user base or the IT environment.<\/p>\n <\/div>\n\n

    \n

    Can training replace technical protection?<\/h3>\n

    No, training complements technical protection but cannot fully replace it.<\/p>\n <\/div>\n\n <\/div>\n <\/div>\n <\/div>\n<\/div>\n\n
