  1. Windows VistaInside Out Chapter 30 – Automating Windows Vista Last modified 11-27-07

  2. Editions • The Automation Tools are the same in all editions of Windows Vista

  3. Four Ways to Automate Tasks • Task Scheduler • Easiest and simplest • Batch Programs • Carried over from MS-DOS • Windows Script Host • Can run scripts written in VBScript, JScript, and other languages • Windows PowerShell • Not included in Vista by default • A free download from Microsoft

  4. We Only Cover Task Scheduler • The other three methods are not part of this class: • Batch Programs • Windows Script Host • Windows PowerShell

  5. New Features in Task Scheduler • Implemented as a Microsoft Management Console (MMC) snap-in • More information about tasks • Integrated with the Event Viewer • Events can trigger tasks • More extensive triggering and scheduling options • Launch when computer is idle • Launch when a specific user logs on

  6. Launching Task Scheduler • Control Panel, System And Maintenance, Scroll to bottom, under Administrative Tools, Schedule Tasks • Or taskschd.msc at a Command Prompt • Or Start, search for "Task Scheduler"

  7. Task Scheduler Window • View, Customize, and then deselect Action Pane • To update, Action, Refresh

  8. Display All Running Tasks • Select top node in left pane • Action, Display All Running Tasks

  9. Task Details • Browse to task in folder tree to see read-only details in lower pane • To modify them, right-click task name in the top pane and click Properties

  10. Task Scheduler Terminology • Trigger • The time or the event that causes a task to run • Action • What the task does • Condition • An additional requirement that, along with the trigger, must be met for the task to run • Setting • A property that affects the behavior of a task

  11. Demonstration: System Restore • See when Restore Points were made

  12. Scheduling Tasks with the Schtasks Command • Schtasks /Create • Schtasks /Change • Schtasks /Delete • Schtasks /End • Schtasks /Query • Schtasks /Run

  13. Windows VistaInside Out Chapter 31 – Advanced Security Management

  14. Topics • Windows Firewall With Advanced Security • User Rights • Auditing

  15. Editions • Windows Firewall With Advanced Security is the same in all editions of Windows Vista • User rights are the same in all Editions • But the console for viewing and modifying them is available only in the Business, Enterprise, and Ultimate editions

  16. Editions • Auditing is preconfigured and cannot be changed in the home editions • The other editions allow you to control exactly what you audit

  17. Protecting a System with Windows Firewall • For basic control, use Windows Firewall application in Control Panel • For more advanced tasks, use: • Windows Firewall With Advanced Security, or • The Netsh command-line utility

  18. To Open Windows Firewall with Advanced Security • Start, FIRE • or • wf.msc • at a command prompt

  19. Viewing Active Rules and Security • A firewall rule defines how a given network packet is handled by the Windows Firewall • Exceptions in Windows Firewall comprise one of more rules

  20. Inbound Rules • There are a lot of rules • You can make custom rules if you like (see textbook)

  21. Demonstration • Restricting Remote Desktop to LAN connections • Double-click "Remote Desktop (TCP-In)

  22. Demonstration • On the Advanced tab, click Customize • Select desired interface types

  23. Logging Firewall Activity • Right-click the top-level folder: • Windows Firewall With Advanced Security On Local Computer • Properties • Choose the desired profile's tab • Domain, Private, or Public

  24. Firewall Log • To view the log, you need an elevated Notepad window

  25. Logging Settings • In the Logging section, click Customize • Logging successful packets is usually worthless—too much boring data

  26. Using the Netsh Command to Manage Windows Firewall • You can enable Windows Firewall with this command: • netsh firewall set opmode enable • There are a lot of netsh commands, to use some of them, do the Server Core project

  27. Testing Your Computer’s Network Security • To see the currently active network connections, at a Command Prompt: • netstat -a | more • You could just use netstat –a, but it would scroll off the screen • This command uses numbers instead of DNS names, and shows process IDs: • netstat -aon | more

  28. Correlating Process IDs • Netstat shows the PID that is listening • Task Manager shows the process

  29. Managing User Rights • A user right is authorization to perform an operation that affects an entire computer • A permission, is authorization to perform an operation on a specific object—such as a file or a folder

  30. Local Security Policy • Available only on Business, Enterprise, or Ultimate editions of Vista. • At a command prompt, type secpol.msc

  31. Default User Rights • These User Rights are what makes an Administrator different from a User • It is not common to change them from their default settings • You could change "Bypass Traverse Checking" to prevent security problems in nested folders

  32. Auditing Security Events • Auditing writes events into the Security Log, when • A monitored folder is accessed • Logon or Logoff • Many other possibilities

  33. Enabling Auditing • Before any events can be written to the Security log, you must enable Auditing in Local Security Settings • Enable thedesiredauditing

  34. Monitoring Access to Folders and Files • Right-click file or folder, Properties, Security tab, Advanced, Auditing tab • Add, Everyone • Check events to audit

  35. Security Events • Now you will see a LOT of events from the auditing
