What is the scope of the advisory?
The purpose of this advisory is to notify customers that an update is available for supported editions of Windows 7, Windows Server 2008R2, Windows 8, and Windows Server 2012 that expands the Windows Command Line Audit Process Creation policy to include the command information that is passed to every process. This new feature, when enabled and configured, creates an event log every time a process is created and includes the command line information passed to that process. The events will be logged to the existing event ID 4688 and saved to the Windows Security Log. Monitoring these events can provide valuable information to help administrators investigate and troubleshoot security-related issues.
How do I get this update?
The functionality discussed in this advisory can be obtained by installing the 3004375 update directly (see Microsoft Knowledge Base Article 3004375). Note that the update is also bundled with the updates being released in MS15-011 (see Microsoft Knowledge Base Article 3000483) and MS15-015 (see Microsoft Knowledge Base Article 3031432). Either update will install the 3004375 update automatically.
What is the Audit Process Creation policy?
The Audit Process Creation policy is a security audit policy that determines whether or not the operating system generates an audit event when a process is created. When enabled, an event log with ID 4688 is generated and saved to the Windows Security Log. Since the policy is disabled by default, no audit events are logged when processes are created unless the policy is enabled. Furthermore, the Audit Process Creation Policy must be enabled for the expanded command line auditing feature described in this security advisory to work. For more information about the Audit Process Creation Policy, please see the Audit Process Creation.
How does this update change security event ID 4688?
After installing and configuring this security update, administrators will see a newly added element in the 4688 security event called Process Command Line, which contains the entire command that was executed for the event in question.
How do I configure the features that are provided with this update?
The features that are provided with this update are disabled by default. After installing the update, administrators will first need to enable the Audit Process Creation policy, and then enable the feature for expanded logging. For more information, see Microsoft Knowledge Base Article 3004375.
Why is the update not available for supported editions of Windows 8.1 and Windows Server 2012 R2?
The security update is not being provided for supported editions of Windows 8.1 and Windows Server 2012 R2 because the new features discussed in this advisory are already present in these operating systems.
Apply the update for supported releases of Microsoft Windows
The majority of customers have automatic updating enabled and will not need to take any action because the 3004375 update will be downloaded and installed automatically. Customers who have not enabled automatic updating need to check for updates and install this update manually. For information about specific configuration options in automatic updating, see Microsoft Knowledge Base Article 294871.
For administrators and enterprise installations, or end users who want to install the 3004375 update manually, Microsoft recommends that customers apply the update using update management software, or by checking for updates using the Microsoft Update service. For more information on how to manually apply the update, see Microsoft Knowledge Base Article 3004375.
Enable Audit Process Creation policy and enable Expanded Logging
After installing the update, administrators will first need to enable the Audit Process Creation policy, and then enable the feature for expanded logging. For more information, see Microsoft Knowledge Base Article 3004375.
