This container allows system administrators and policy engineers to validate custom Administrative Templates (&lt;code&gt;.admx&lt;/code&gt;) and language resource files (&lt;code&gt;.adml&lt;/code&gt;) against official Microsoft XML Schema Definitions (XSD) without having to manually build or run dependencies locally.&lt;/p&gt;
&lt;p&gt;It is particularly useful for pipeline automation when building custom GPO baselines.&lt;/p&gt;
&lt;h3 id="key-use-cases--features"&gt;Key Use Cases &amp;amp; Features&lt;/h3&gt;
&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;Schema Compliance:&lt;/strong&gt; Verifies namespace structures, element definitions, and category mappings against official Group Policy schemas.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Pipeline Integration:&lt;/strong&gt; Easily integrate ADMX lint checks into GitHub Actions, GitLab CI, or custom DevSecOps pipelines.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Zero Local Setup:&lt;/strong&gt; Eliminates the need to configure build environments or C++ compilers on local development workstations.&lt;/li&gt;
&lt;/ul&gt;
&lt;h3 id="quick-usage"&gt;Quick Usage&lt;/h3&gt;
&lt;p&gt;Run the linter on your ADMX files by mounting your templates folder into the container:&lt;/p&gt;
&lt;div class="highlight"&gt;&lt;pre tabindex="0" class="chroma"&gt;&lt;code class="language-bash" data-lang="bash"&gt;&lt;span class="line"&gt;&lt;span class="cl"&gt;docker run --rm -v &lt;span class="k"&gt;$(&lt;/span&gt;&lt;span class="nb"&gt;pwd&lt;/span&gt;&lt;span class="k"&gt;)&lt;/span&gt;/policies:/workspace harvester57/docker-admxlint:latest /workspace
&lt;/span&gt;&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;</description></item><item><title>exploit-protection-policy</title><link>https://me.harvester.fr/project/exploit-protection-policy/</link><pubDate>Wed, 22 May 2024 00:00:00 +0000</pubDate><guid>https://me.harvester.fr/project/exploit-protection-policy/</guid><description>&lt;p&gt;&lt;strong&gt;Exploit-Protection-policy&lt;/strong&gt; provides a production-hardened Exploit Protection (EP) policy tailored for Windows 10 and Windows 11 systems. It combines multiple industry-standard security baselines with advanced restrictions to maximize security without breaking compatibility with everyday applications.&lt;/p&gt;
&lt;p&gt;This policy has been tested in air-gapped systems to protect endpoints from advanced threat vectors while maintaining productivity.&lt;/p&gt;
&lt;h3 id="merged-security-baselines"&gt;Merged Security Baselines&lt;/h3&gt;

&lt;li&gt;&lt;strong&gt;DISA STIG&lt;/strong&gt; Exploit Protection v3.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Microsoft Security Baseline&lt;/strong&gt; Exploit Protection policy (specifically aligned for enterprise systems).&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;milgradesec&amp;rsquo;s&lt;/strong&gt; custom Exploit Protection rule configurations.&lt;/li&gt;
&lt;/ul&gt;
&lt;h3 id="key-protections-enforced"&gt;Key Protections Enforced&lt;/h3&gt;
&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;System-Wide Mitigations:&lt;/strong&gt; Enforces fundamental protections such as Control Flow Guard (CFG), Data Execution Prevention (DEP), Address Space Layout Randomization (ASLR), and Heap Protection by default.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Advanced Payload Controls:&lt;/strong&gt; Restricts execution vectors using Export Address Filtering (EAF/EAF+), Import Address Filtering (IAF), and Return-Oriented Programming (ROP) mitigations.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Image &amp;amp; Code Integrity Restrictions:&lt;/strong&gt; Blocks loading of low-integrity or remote images, preventing malicious library injection.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Application-Specific Tuning:&lt;/strong&gt; Includes pre-configured exceptions and application rules to balance high-security containment with software compatibility.&lt;/li&gt;
