System Options and Security Restrictions.
System Options and Security Restrictions.
Options affect the whole PC.
- Restricting Access to the Event Logs - The Windows NT event log contains records documenting application, security and system events taking place on the machine. These logs can contain sensitive data, and by default, the Guest account has access to view them. This tweak allows you to restrict access to administrators and system accounts.
- Stopping the KnownDLLs Vulnerability - In Windows NT the core operating system DLLs are kept in virtual memory and shared between the programs running on the system. This has exposed a vulnerability that could allow a user to gain administrative privileges on the computer the user is interactively logged onto.
- Clear the Page File at System Shutdown - Windows normally does not clear or recreate the page file. On a heavy used system this can be both a security threat and performance drop. Enabling this setting will cause Windows to clear the page file whenever the system is shutdown.
- Disable the Automatic Restarting of the Shell - By default if the Windows user interface or one of its components fails, the interface is restarted automatically, this can be changed so that you must restart the interface by logging off and logging on again manually.
- Disable Shutdown from Authentication Dialog Box - When this setting is enabled a [Shutdown] button is not displayed in authentication dialog box when the system first starts. This does not allow you to shutdown a system without logging in.
- Disable Multiple User Sessions and Fast User Switching - By default, Windows XP gives you an ability to switch between users without logging off that keeps all active users on your PC with all started processes and programs. On a heavy used system this can be both a security threat and performance drop. This option disables multiple user sessions and fast user switching on your PC.
- Enable Advanced File System and Sharing Security - This setting is used to enable the ability to control advanced NTFS permissions on local and shared files.
- Require Users to Press Ctrl+Alt+Delete Before Logon - This setting controls whether users are required to press Ctrl + Alt + Delete as a security precaution before logging into the system.
- Use Active Authentication for Unlock and Screen Saver - This setting controls whether a full login should be performed when a workstation is unlocked or a password is used with the screen saver. Normally Windows will not check some settings such as whether the account has been locked out.
- Secure Desktop Restriction - This restriction is used to stop interactive users from snooping on other user sessions by exploiting a Windows vulnerability. This feature is enabled by default but may interfere with some software applications.
- Disable Windows Installer - This restriction allows you to prevent users from adding and removing software applications with Windows Installer.
