About
System.Threading.AccessControl provides types that enable you to control access to threading synchronization primitives. This includes the ability to control access to Mutexes, Semaphores, and Events using Windows Access Control Lists (ACLs).
Key Features
- Extension methods to allow ACL modifications on
Mutex
,Semaphore
, andEventWaitHandle
. - Simplified security management for threading synchronization objects.
How to Use
using System.Security.AccessControl;
using System.Security.Principal;
// Create a string representing the current user.
string user = $"{Environment.UserDomainName}\\{Environment.UserName}";
// Create a security object that grants no access
MutexSecurity mutexSecurity = new MutexSecurity();
// Add a rule that grants the current user the right to enter or release the mutex
MutexAccessRule rule = new MutexAccessRule(user, MutexRights.Synchronize | MutexRights.Modify, AccessControlType.Allow);
mutexSecurity.AddAccessRule(rule);
// Add a rule that denies the current user the right to change permissions on the mutex
rule = new MutexAccessRule(user, MutexRights.ChangePermissions, AccessControlType.Deny);
mutexSecurity.AddAccessRule(rule);
// Display the rules in the security object
ShowSecurity(mutexSecurity);
// Add a rule that allows the current user the right to read permissions on the mutex
// This rule is merged with the existing Allow rule
rule = new MutexAccessRule(user, MutexRights.ReadPermissions, AccessControlType.Allow);
mutexSecurity.AddAccessRule(rule);
// Display the rules in the security object
ShowSecurity(mutexSecurity);
static void ShowSecurity(MutexSecurity security)
{
Console.WriteLine("\nCurrent access rules:\n");
foreach (MutexAccessRule ar in security.GetAccessRules(true, true, typeof(NTAccount)))
{
Console.WriteLine($" User: {ar.IdentityReference}");
Console.WriteLine($" Type: {ar.AccessControlType}");
Console.WriteLine($" Rights: {ar.MutexRights}");
Console.WriteLine();
}
}
/*
* This code example produces output similar to following:
*
* Current access rules:
*
* User: TestDomain\TestUser
* Type: Deny
* Rights: ChangePermissions
*
* User: TestDomain\TestUser
* Type: Allow
* Rights: Modify, Synchronize
*
*
* Current access rules:
*
* User: TestDomain\TestUser
* Type: Deny
* Rights: ChangePermissions
*
* User: TestDomain\TestUser
* Type: Allow
* Rights: Modify, ReadPermissions, Synchronize
