Stung by last summer's CrowdStrike meltdown, which crashed Windows PCs and servers worldwide, Microsoft is rolling out a wide range of security changes to Windows. Here's what to expect over the next year
Analysis Summary
The provided context is truncated and primarily consists of navigation links and trending articles from ZDNET, with only the title indicating the subject matter: "Microsoft to tighten Windows security dramatically in 2025 - here's how."
Since the specific details of Microsoft's security tightening plans for 2025 are missing, the following summary will be based on **inferred best practices and likely future directions** for Windows security hardening, structured as per the request, assuming the article covers a shift towards stronger default security postures.
# Best Practices: Hardening Windows Security Post-2025
## Overview
These practices address the anticipated increased stringency in Microsoft's Windows security posture starting in 2025. They focus on proactively enabling advanced security features, enforcing strong baseline configurations, and adopting modern authentication and device health standards to mitigate evolving threats.
## Key Recommendations
### Immediate Actions (Preparation & Assessment)
1. **Inventory Security Feature Gaps:** Conduct an immediate audit of all active Windows endpoints (especially Windows 10/11) to identify which devices are not currently running the minimum required OS versions that support advanced security features (e.g., Windows 11 eligibility).
2. **Verify Administrator Rights Reduction:** Review and revoke excessive local administrator privileges across all non-IT staff user accounts to align with the principle of least privilege.
3. **Enable Core Security Features:** Ensure that essential built-in security features like **Smart App Control (SAC)** and **User Account Control (UAC)** are enabled and configured to their recommended maximum restriction levels across all active domains/workgroups.
### Short-term Improvements (1-3 months)
1. **Mandate TPM 2.0 and Secure Boot:** Begin the remediation process for any hardware that does not meet the requirements for Trusted Platform Module (TPM) version 2.0 and Secure Boot, as these are foundational for modern OS security integrity.
2. **Implement Conditional Access Policies:** Integrate device health checks (e.g., BitLocker status, required patch level) into the organization's conditional access policies to block non-compliant devices from accessing critical resources.
3. **Automate Patch and Driver Rollouts:** Establish automated deployment rings and strict timelines for testing and deploying Windows security updates and crucial hardware drivers via WSUS or Microsoft Endpoint Manager/Intune.
### Long-term Strategy (3+ months)
1. **Migrate to Passwordless Authentication:** Develop and execute a roadmap to fully transition user authentication away from traditional passwords toward Windows Hello for Business (WHfB), FIDO2 security keys, or certificate-based authentication.
2. **Standardize on LAPS (Local Administrator Password Solution):** Deploy LAPS universally across all domain-joined machines to randomize and manage local administrator accounts, preventing lateral movement via compromised default credentials.
3. **Embrace Memory Integrity and HVCI:** Configure and enforce **Hypervisor-Enforced Code Integrity (HVCI)** and related memory protection features across the entire fleet to prevent the execution of unsigned or malicious drivers and code in kernel space.
## Implementation Guidance
### For Small Organizations
* **Focus on Native Tools:** Prioritize utilizing built-in Windows security tools (Defender for Endpoint, Windows Security Center dashboards) over third-party solutions to minimize cost and complexity.
* **Centralize with Azure AD:** If not already done, centralize user management using Azure Active Directory to facilitate easier rollout of modern policies (e.g., Conditional Access).
### For Medium Organizations
* **Phased Policy Rollout:** Use the Group Policy management infrastructure (or Intune) to deploy new security baselines incrementally, starting with pilot groups, before applying organization-wide using tiered organizational units (OUs).
* **Implement AV/EDR Consolidation:** Ensure that Microsoft Defender for Endpoint is fully configured and centrally managed, leveraging features like Attack Surface Reduction (ASR) rules.
### For Large Enterprises
* **Develop a Security Baseline Standard:** Adopt and document a formal security baseline derived from frameworks like CIS Benchmarks for Windows Server and Desktop.
* **Automated Remediation Workflows:** Integrate security monitoring alerts (SIEM) with automated remediation actions via tools like Microsoft Sentinel or Security Orchestration, Automation, and Response (SOAR) platforms to handle common misconfigurations or violations instantly.
## Configuration Examples (Inferred Best Practices)
| Feature | Recommended Configuration Action | Purpose |
| :--- | :--- | :--- |
| **Smart App Control (SAC)** | Enable in Audit mode first, then transition to **Enforce mode**. | Blocks execution of unauthorized applications and potentially malicious scripts. |
| **Credential Guard** | Enable via Group Policy or MDM configuration profile. | Protects NTLM hashes and Kerberos tickets by virtualizing the LSA subsystem. |
| **Attack Surface Reduction (ASR)** | Apply rules 1, 3, 6, 7, and 12 to **Block** mode. | Restricts common malware execution techniques (e.g., blocking Office apps from creating executable content or launching scripts). |
| **BitLocker** | Configure policies to enforce **AES-XTS 256-bit encryption** and automatically suspend BitLocker protection if Secure Boot/TPM state changes unexpectedly. | Ensures full disk encryption compliance and tamper detection. |
## Compliance Alignment
* **CIS Benchmarks:** Aim to meet Level 1 and, where feasible, Level 2 controls for Windows 10/11 and Windows Server configurations.
* **NIST Cybersecurity Framework (CSF):** Focus on strengthening the **Protect (PR)** function through enhanced identity management and data security measures.
* **ISO/IEC 27001:** Align with controls related to Access Control (A.9) and Cryptographic Protection (A.10) through mandatory MFA/Passwordless implementation.
## Common Pitfalls to Avoid
1. **Ignoring Legacy Systems:** Failing to isolate or immediately phase out any operational systems (e.g., Windows Server 2012 R2, unsupported Windows 10 builds) that cannot support mandatory 2025 baseline security features (like TPM 2.0 or HVCI).
2. **Audit Mode Default:** Leaving security features like Smart App Control or ASR rules indefinitely in Audit mode without setting a firm date for transition to enforcing blocks.
3. **"Set and Forget" Policy:** Assuming that a one-time policy deployment is sufficient; security configuration drifts over time due to user activity or hardware changes. Continuous monitoring and drift remediation are essential.
