23. NetTech Solutions Planning an Audit Policy Understanding Audit Policies –An audit policy defines the types of security events that Windows XP Professional records in the security log on each computer. The security log allows you to track the events that you specify. –Track the success and failure of events –Eliminate or minimize the risk of unauthorized use of resources

24. NetTech Solutions Determining What to Audit The types of events that you can audit include the following: Accessing files and folders Logging on and off Shutting down a computer running Windows XP Professional Starting a computer running Windows XP Professional Changing user accounts and groups Attempting to make changes to Active Directory objects (only if your Windows XP Professional computer is part of a domain)

25. NetTech Solutions Audit policy include: Determine whether you need to track system usage trends. Review security logs frequently. Define an audit policy that is useful and manageable.

26. NetTech Solutions Implementing an Audit Policy For computers running Windows XP Professional, you set up an audit policy for each individual computer. Auditing Requirements You must have the Manage Auditing And Security Log user right for the computer on which you want to configure an audit policy or review an audit log. By default, Windows XP Professional grants these rights to the Administrators group. The files and folders to be audited must be on NT file system (NTFS) volumes.

27. NetTech Solutions Setting up Auditing Setting up auditing is a two-part process: 1.Set the audit policy. The audit policy enables auditing of objects but doesn't activate auditing of specific objects. 2.Enable auditing of specific resources. You designate the specific events to audit for files, folders, printers, and Active Directory objects. Windows XP Professional then tracks and logs the specified events.

28. NetTech Solutions Setting an Audit Policy The first step in implementing an audit policy is selecting the types of events for Windows XP Professional to audit.

29. NetTech Solutions Auditing Access to Files and Folders When you set your audit policy to audit object access, you enable auditing for specific files and folders and specify which types of access, by which users or groups, to audit.

30. NetTech Solutions Auditing Access to Printers After you select the printer, you use the same steps that you use to set up auditing on files and folders.

31. NetTech Solutions Locating Events When you first start Event Viewer, it automatically displays all events that are recorded in the selected log. To filter or find events, start Event Viewer, and then on the View menu click Filter or click Find.

32. NetTech Solutions Managing Audit Logs You can track trends in Windows XP Professional by archiving event logs and comparing logs from different periods. To configure the settings for logs, select the log in Event Viewer, and then on the Action menu, click Properties to display the Properties dialog box for the log.

33. NetTech Solutions Archiving Logs Archiving security logs allows you to maintain a history of security-related events.

45. Monitoring and Managing Shared Folder Resources Chapter Seventeen

46. NetTech Solutions Monitoring Network Resources The three primary reasons why it is important to assess and manage network resources 1.Maintenance 2.Security 3.Planning

47. NetTech Solutions Requirements to Monitor Network Resources Not all users can monitor access to network resources Administrators or Server Operators for the domain can monitor… –All computers in the domain. Administrators or Power Users for a member server can monitor… –Local or remote computers in the workgroup.

48. NetTech Solutions Requirements to Monitor Network Resources Only members of the Administrators group or the Power Users group can monitor resources for the local computer or for a remote computer in the workgroup.

49. NetTech Solutions Monitoring Access to Shared Folders Computer Management snap-in Shared Folders snap-in

50. NetTech Solutions Information in Shared Folders Shared Folder Shared Path Type Number of Client Connections Comment

51. NetTech Solutions Determining How Many Users Can Access You can use the Computer Management snap-in or Shared Folders snap-in to determine the maximum number of users that are permitted to gain access to a folder. You can also use the Computer Management snap-in or Shared Folders snap-in to determine whether the maximum number of users that are permitted to gain access to a folder has been reached. In Windows XP Professional the maximum is 10, but you can set this to a lower value.

52. NetTech Solutions Monitoring Shared Folders Modifying Shared Folder Properties –You can modify existing shared folders, including shared folder permissions, from the Shares folder.

53. NetTech Solutions Monitoring Open Files Information Available in the Open Files Folder –Open File –Accessed By –Type –The number of locks on the file –Open Mode

54. NetTech Solutions Disconnecting Users from Open Files Disconnecting all users from all open files. Disconnecting all users from one open file CAUTION: Disconnecting users from open files can result in data loss.

55. NetTech Solutions Practice: Pages 17-7 Monitoring Shared Folders

56. NetTech Solutions Creating and Sharing Local and Remote Folders You can run the Create Shared Folder Wizard to create a new folder and share it. When you use the Computer Management snap- in or Shared Folders snap-in to share an existing folder or to create a new shared folder and share it, Windows XP Professional assigns the Full Control shared folder permission to the Everyone group by default.

57. NetTech Solutions Basic Shared Permissions The Create Shared Folder wizard assigns the Full Control share permission to the Everyone group and the Full Control NTFS permission for the folder to the Everyone group Administrators Have Full Control, Other Users Have Read-Only Access Administrators Have Full Control Share and NTFS, Other Users Have No Access Customize Share And Folder Permissions

58. NetTech Solutions Shared Folders NOTE: Using either the Computer Management snap-in or the Shared Folders snap-in is the only way to create a shared folder on a remote computer. Otherwise, you need to be physically located at the computer where the folder resides to share it.

59. NetTech Solutions Practice: Pages 17-13 Creating a Shared Folders

60. NetTech Solutions Monitoring Network Users You can disconnect users and send administrative messages to computers and users, including computers and users who aren't currently gaining access to network resources.

61. NetTech Solutions Monitoring User Sessions You can disconnect one or more users to free idle connections to the shared folder, to prepare for a backup or restore operation, to shut down a server, and to change group membership and permissions for the shared folder. You use the Sessions folder in the Computer Management snap-in or the Shared Folders snap-in to view a list of the users with a current network connection to the computer that you are monitoring

62. NetTech Solutions Monitoring User Sessions Use Computer Management Snap-in

63. NetTech Solutions Disconnecting Users You can disconnect one or all users with a network connection to a computer. You disconnect users so that you can do any of the following: –Have changes to shared folder and NTFS permissions take effect immediately. –Free idle connections on a computer so that other users can make a connection when you reach the maximum number of connections. –Shut down a server.

64. NetTech Solutions Sending Administrative Messages to Users You can send administrative messages to one or more users or computers. You do this for these reasons: –Perform a backup or restore operation –Disconnect users from a resource –Upgrade software or hardware –Shut down the computer
