Tutorial / Cram Notes
Windows Defender has evolved into a full-fledged suite known as Windows Defender Advanced Threat Protection (ATP), which provides a variety of tools to secure Windows clients.
- Antivirus and Antimalware Protection: Ensure that Windows Defender Antivirus is properly configured with real-time protection and that the definitions are regularly updated. Automatic sample submission should be enabled for improved threat response.
-
Exploit Guard: This tool provides a set of features to protect against zero-day exploits. Use the Attack Surface Reduction (ASR) rules to minimize the exploits’ potential impact. For instance, ASR can be configured to:
- Block executable content from email and webmail
- Block Office applications from creating child processes
- Block Win32 API calls from Office macros
- Windows Defender Application Guard (WDAG): Integrate WDAG to isolate enterprise-defined untrusted sites, keeping the system protected while browsing. This feature uses Hyper-V-powered containers to isolate potentially harmful websites.
Planning for BitLocker Implementation
To protect data at rest, BitLocker offers device encryption that can be managed through Group Policy or Microsoft Intune.
- BitLocker Drive Encryption: Plan for full-disk encryption on all systems. Devices with a Trusted Platform Module (TPM) can use it for additional security. The use of BitLocker with TPM provides a more secure startup process.
- BitLocker Network Unlock: Office devices can be configured to automatically unlock when connected to a trusted wired network, enabling seamless user experience while maintaining security when away from the trusted environment.
Configuration of User Account Control (UAC)
User Account Control helps prevent unauthorized changes to the operating system. Administrators should configure UAC to:
- Prompt users for consent with or without dimming the desktop, depending upon security requirements.
- Prompt for credentials on the secure desktop when admin-level permission is required for standard users.
Security Baseline Compliance
Security baselines are predefined groups of settings recommended by Microsoft. Use Microsoft Security Compliance Toolkit to apply these baselines for a more secure client environment.
- Group Policy Objects (GPOs): Deploy security baseline settings using GPOs across the organization for consistent security configuration.
- Microsoft Intune: Apply security baselines to devices managed by Intune to ensure compliance with organizational standards.
Advanced Threat Analytics (ATA)
Organizations should plan to deploy Advanced Threat Analytics for on-premises behavioural analysis which helps in detecting suspicious activities and known security threats.
- Continuous monitoring and analysis of user, device, and resource behaviors.
- Utilization of machine learning to detect irregular activities.
- Integration with other Microsoft 365 services for a cohesive security stance.
Integration with Azure Advanced Threat Protection (Azure ATP)
Azure ATP provides cloud-based security solutions and can integrate with Windows client security features to enhance the detection and response capabilities.
- Detect and investigate advanced attacks on-premises.
- Seamless integration with cloud intelligence for a comprehensive security solution.
- Real-time monitoring, correlation of activities, and profiling of user and device behavior.
Below is a comparative table showcasing the primary security features and their modes of application:
| Security Feature | Configuration Method | Purpose |
|---|---|---|
| Windows Defender Antivirus | GPO, Intune, PowerShell | Real-time protection against malware and viruses. |
| Windows Defender Exploit Guard | GPO, Intune, PowerShell | Rules to reduce attack surfaces. |
| BitLocker Drive Encryption | GPO, Intune, PowerShell | Full-disk encryption to protect against data theft. |
| User Account Control | GPO, Control Panel | Prevent unauthorized system changes. |
| Security Compliance Baselines | GPO, Microsoft Security Compliance | Standardization of security settings. |
| Advanced Threat Analytics | On-premises installation | Behavioural analytics for detecting suspicious activity. |
| Azure Advanced Threat Protection | Azure Portal, PowerShell | Cloud-based detection of on-premises attacks. |
By setting up these additional security features, IT professionals can ensure a much more robust Windows client security posture. It’s not only about protecting against known threats, but also about creating an adaptive and resilient environment that can respond to new challenges as they arise. This will be an essential aspect of the knowledge base for candidates preparing for the MS-101 Microsoft 365 Mobility and Security exam. It’s critical to not only understand these features and how to implement them, but also to be able to design and optimize a full security strategy that aligns with the unique needs of the organization.
