implement and manage security baselines

Security baselines are essential components for organizations to protect their networks, systems, and data in the digital environment. Implementing these sets of standardized configurations can greatly enhance the organization’s security posture while reducing its vulnerability to cyber-attacks. Managing such baselines can be a complex task, but with the guidance provided by MS-101 Microsoft 365 Mobility and Security exam, it becomes easier and more systematic.

Implementation of Security Baselines

Security baselines in Microsoft 365 refer to pre-configured security settings that you can apply to devices, users, and services in your organization. These settings align with Microsoft’s recommendations, thus providing your organization with a secure starting point to customize according to your specific needs.

Workspace Security Baselines

One example of security baselines is in Microsoft’s Intune service, where you can create profiles for device configuration that apply baseline security settings to your Windows 10 devices.

The steps for setting up a security baseline for device configuration in Microsoft Intune are as follows:

• In the Microsoft Endpoint Manager admin center, select Devices > Configuration Profiles > Create Profile.
• Enter the following properties:
• Name: Enter a descriptive name for the new profile.
• Description: Enter a description for the profile.
• Platform: Choose the platform of your devices.
• Profile Type: Select Templates > Security Baseline.
• In Baseline settings, choose your desired configuration settings.

User and Service Security Baselines

For enhancing the security of users and services, Microsoft 365 offers ‘Security Defaults’ – pre-designed security settings considering common attack vectors.

Just follow these steps:

• Sign into the admin center.
• Select Settings > Org Settings > Services & add-ins > Azure AD.
• Choose Manage Security Defaults.
• Set Enable Security Defaults to ‘Yes’ or ‘No’ and save the settings.

Managing Security Baselines

Microsoft 365 allows admins to easily manage security baselines after they’ve been implemented.

• In the Microsoft Endpoint Manager admin center, select Devices > Configuration Profiles to see the list of your organization’s profiles.
• Select a profile to see its properties, settings, and assignments, and to monitor its status.
• Use the Assignments tab to choose which users or groups the profile should apply to.
• The Monitor tab shows you a status report of the profile’s deployment.

Comparison of Security Baselines

It is recommended to review the individual settings of each security baseline and compare the baseline versions before applying them. In Microsoft Intune, admins can see a side-by-side comparison of the changes in their baseline versions, including which settings have been added, modified, or removed.

Conclusion

Implementing security baselines optimizes security settings across organization assets. Managing those baselines, tracking updates, and making adjustments help in ensuring their effectiveness and maintain the organization’s overall-security posture. MS-101 exam equips professionals with the ability to effectively implement and manage security baselines in Microsoft 365, thereby ensuring the organization’s immunity against most threats.
