Service Permissions
Windows Service Permissions
Windows services require specific permissions to operate effectively and securely. These permissions determine who can interact with services in various ways, such as starting, stopping, or configuring them. Key concepts include:
Local System Account: Services run with extensive privileges on the local system and have almost unrestricted access to local resources.
Network Service Account: Offers services the ability to communicate over the network, using the machine's identity, but with limited local privileges.
Local Service Account: Provides services with the ability to run with minimal privileges on the local machine and anonymous credentials on the network.
User Accounts: Services can be configured to run under specific user accounts, providing fine-grained control over their permissions.
Setting Permissions
Permissions for Windows services are typically set in the service properties in the Services MMC snap-in, under the "Log On" tab, or via the command line using tools like sc.exe.
Security Descriptors define who can interact with the service and in what ways, using a Security Descriptor Definition Language (SDDL) string.
Common permissions include:
Start, stop, and pause: Control the operational state of the service.
Read and write settings: Modify service configuration.
Read status: View current state and other service details.
It's crucial to carefully manage these permissions to ensure system security and functionality.
