    <summary>Represents the access control and audit security for a file or directory.</summary>
    <remarks>
      <format type="text/markdown"><![CDATA[

## Remarks
 The <xref:System.Security.AccessControl.FileSystemSecurity> class is the base class for the <xref:System.Security.AccessControl.FileSecurity> and <xref:System.Security.AccessControl.DirectorySecurity> classes. These classes represent all of the access rights for a system file or directory and define how access attempts are audited.

 The <xref:System.Security.AccessControl.FileSystemSecurity> class represents access and audit rights as a set of rules. Each access rule is represented by a <xref:System.Security.AccessControl.FileSystemAccessRule> object, while each audit rule is represented by a <xref:System.Security.AccessControl.FileSystemAuditRule> object.

 The <xref:System.Security.AccessControl.FileSystemSecurity> class is an abstraction of the underlying Microsoft Windows file security system. In this system, each file or directory has a discretionary access control list (DACL), which controls access to the file or directory, and a system access control list (SACL), which specifies the access control attempts that are audited. The <xref:System.Security.AccessControl.FileSystemAccessRule> and <xref:System.Security.AccessControl.FileSystemAuditRule> classes are abstractions of access control entries (ACEs) that comprise DACLs and SACLs.

 The <xref:System.Security.AccessControl.FileSystemSecurity> class hides many of details of DACLs and SACLs; you do not have to worry about ACE ordering or null DACLS.

Use the following methods to add or retrieve ACL information from a file:

- <xref:System.IO.FileSystemAclExtensions.SetAccessControl(System.IO.FileInfo,System.Security.AccessControl.FileSecurity)?displayProperty=nameWithType>
- <xref:System.IO.FileSystemAclExtensions.GetAccessControl(System.IO.FileInfo)?displayProperty=nameWithType>

## Examples
 The following code example uses the <xref:System.Security.AccessControl.FileSecurity> class to add and then remove an access control list (ACL) entry from a file. You must supply a valid user or group account to run this example.

## Remarks
 The recommended way to create access control rules is to use the constructors of the <xref:System.Security.AccessControl.FileSystemAccessRule> class.

 The return type of the <xref:System.Security.AccessControl.FileSystemSecurity.AccessRuleFactory*> method is the base class, <xref:System.Security.AccessControl.AccessRule>, but the return value can be cast safely to the derived class.

## Remarks
 The <xref:System.Security.AccessControl.FileSystemSecurity.AddAccessRule*> method adds a new rule to the list of rules contained within a <xref:System.Security.AccessControl.FileSystemSecurity> object.

 If an access control list (ACL) already exists for the specified rule, the <xref:System.Security.AccessControl.FileSystemSecurity.AddAccessRule*> method will still add the rule, with one exception: a <xref:System.Security.AccessControl.FileSystemAccessRule> object created using the <xref:System.Security.AccessControl.AccessControlType.Deny> enumeration value supersedes an object created using the <xref:System.Security.AccessControl.AccessControlType.Allow> enumeration value.

Use the following methods to add or retrieve ACL information from a file:

- <xref:System.IO.FileSystemAclExtensions.SetAccessControl(System.IO.FileInfo,System.Security.AccessControl.FileSecurity)?displayProperty=nameWithType>
- <xref:System.IO.FileSystemAclExtensions.GetAccessControl(System.IO.FileInfo)?displayProperty=nameWithType>

 When you add an access rule without setting the <xref:System.Security.AccessControl.FileSystemRights.Synchronize> flag, the <xref:System.Security.AccessControl.FileSystemRights.Synchronize> flag will be automatically added to your rule. If you remove the rule later without specifying the <xref:System.Security.AccessControl.FileSystemRights.Synchronize> flag, the flag will automatically be removed.

## Examples
 The following code example uses the <xref:System.Security.AccessControl.FileSecurity> class to add and then remove an access control list (ACL) entry from a file. You must supply a valid user or group account to run this example.

## Remarks
 The recommended way to create audit rules is to use the constructors of the <xref:System.Security.AccessControl.FileSystemAuditRule> class.

 The return type of the <xref:System.Security.AccessControl.FileSystemSecurity.AuditRuleFactory*> method is the base class, <xref:System.Security.AccessControl.AuditRule>, but the return value can be cast safely to the derived class.

## Remarks
 The <xref:System.Security.AccessControl.FileSystemSecurity.RemoveAccessRule*> method removes either all matching <xref:System.Security.AccessControl.AccessControlType.Deny> access rules or all matching <xref:System.Security.AccessControl.AccessControlType.Allow> access rules from the current <xref:System.Security.AccessControl.FileSystemSecurity> object. For example, you can use this method to remove all <xref:System.Security.AccessControl.AccessControlType.Deny> access rules for a user by passing a <xref:System.Security.AccessControl.FileSystemAccessRule> object created using the <xref:System.Security.AccessControl.AccessControlType.Deny> value, the <xref:System.Security.AccessControl.FileSystemRights.Read> value, and a user account. When you do this, the <xref:System.Security.AccessControl.FileSystemSecurity.RemoveAccessRule*> method removes any deny rules that specify the <xref:System.Security.AccessControl.FileSystemRights.Read> value or the <xref:System.Security.AccessControl.FileSystemRights.Write> value.

Use the following methods to add or retrieve ACL information from a file:

- <xref:System.IO.FileSystemAclExtensions.SetAccessControl(System.IO.FileInfo,System.Security.AccessControl.FileSecurity)?displayProperty=nameWithType>
- <xref:System.IO.FileSystemAclExtensions.GetAccessControl(System.IO.FileInfo)?displayProperty=nameWithType>

 When you add an access rule without setting the <xref:System.Security.AccessControl.FileSystemRights.Synchronize> flag, the <xref:System.Security.AccessControl.FileSystemRights.Synchronize> flag will be automatically added to your rule. If you remove the rule later without specifying the <xref:System.Security.AccessControl.FileSystemRights.Synchronize> flag, the flag will automatically be removed.

## Examples
 The following code example uses the <xref:System.Security.AccessControl.FileSecurity> class to add and then remove an access control list (ACL) entry from a file. You must supply a valid user or group account to run this example.

## Remarks
 The <xref:System.Security.AccessControl.FileSystemSecurity.RemoveAccessRuleSpecific*> method removes the specified <xref:System.Security.AccessControl.AccessControlType.Deny> access rule or the specified matching <xref:System.Security.AccessControl.AccessControlType.Allow> access rule from the current <xref:System.Security.AccessControl.FileSystemSecurity> object. For example, you can use this method to remove a specified <xref:System.Security.AccessControl.AccessControlType.Deny> access rule for a user by passing a <xref:System.Security.AccessControl.FileSystemAccessRule> object created using the <xref:System.Security.AccessControl.AccessControlType.Deny> value, the <xref:System.Security.AccessControl.FileSystemRights.Read> value, and a user account. When you do this, the <xref:System.Security.AccessControl.FileSystemSecurity.RemoveAccessRuleSpecific*> method removes only the deny rule that specifies the <xref:System.Security.AccessControl.FileSystemRights.Read> value. It does not remove any deny rules that specify the <xref:System.Security.AccessControl.FileSystemRights.Write> value.

## Remarks
 The <xref:System.Security.AccessControl.FileSystemSecurity.RemoveAuditRuleSpecific*> method removes the specified matching <xref:System.Security.AccessControl.AccessControlType.Deny> audit rule or the specified matching <xref:System.Security.AccessControl.AccessControlType.Allow> audit rule from the current <xref:System.Security.AccessControl.FileSystemSecurity> object. For example, you can use this method to remove a specified <xref:System.Security.AccessControl.AccessControlType.Deny> audit rule for a user by passing a <xref:System.Security.AccessControl.FileSystemAuditRule> object created using the <xref:System.Security.AccessControl.AccessControlType.Deny> value, the <xref:System.Security.AccessControl.AuditFlags.Failure> value, and a user account. When you do this, the <xref:System.Security.AccessControl.FileSystemSecurity.RemoveAuditRuleSpecific*> method removes only a deny rule that specifies the <xref:System.Security.AccessControl.AuditFlags.Failure> value. It does not remove any deny rules that specify the <xref:System.Security.AccessControl.AuditFlags.Success> value.

## Remarks
 The <xref:System.Security.AccessControl.FileSystemSecurity.ResetAccessRule*> method adds the specified access control list (ACL) rule or overwrites any identical ACL rules that match the `rule` parameter. For example, if the `rule` parameter specifies a <xref:System.Security.AccessControl.FileSystemRights.Read> value and the <xref:System.Security.AccessControl.FileSystemSecurity.ResetAccessRule*> method finds an identical ACL rule that specifies the <xref:System.Security.AccessControl.FileSystemRights.Read> value, the identical rule will be overwritten. If the <xref:System.Security.AccessControl.FileSystemSecurity.ResetAccessRule*> method finds an identical ACL rule that specifies the <xref:System.Security.AccessControl.FileSystemRights.Write> value, the identical rule will also be overwritten.

Use the following methods to add or retrieve ACL information from a file:

- <xref:System.IO.FileSystemAclExtensions.SetAccessControl(System.IO.FileInfo,System.Security.AccessControl.FileSecurity)?displayProperty=nameWithType>
- <xref:System.IO.FileSystemAclExtensions.GetAccessControl(System.IO.FileInfo)?displayProperty=nameWithType>
