Practice 1: Change the current home page in Internet Explorer. Also, spend time working with the available toolbars. Customize the Standard toolbar by changing the buttons that appear. Practice 2: Change how much disk space can be used by Internet Explorer to save temporary files. Practice 3: Change the security level for the Internet zone in Internet Explorer and note the differences in the available security levels. Practice 4: Change the privacy level in Internet Explorer and note the differ ences in the available privacy levels. Practice 5: Create a profile using Internet Explorer s Profile Assistant to store personal information.

Permission objects include the Assert method to enable a method to vouch for all callers. Figure 6-17 shows how a call to Assert stops the runtime from checking the CAS permissions of assemblies higher in the stack. This has two effects: improving performance by reducing the number of permission checks, and allowing underprivileged code to call methods with higher CAS permission requirements.

The final CLR object that is supported by SQL Server is a UDT. Creating custom UDTs is similar to creating user-defined aggregates. The type consists of a CLR type (class or struct) that uses the SqlUserDefinedType attribute to inform SQL Server of its various behaviors. In the following example, you can see the CLR code that is used to define a CLR UDT. This type, called CURRENCY_VALUE, can be used to store a monetary value (a decimal) and its currency code (a string). (Note that this example has not been rigorously tested and should not be used in production code.)

ts << _value; return UIInitPropertyFromString(UI_PKEY_Label, ts.str().c_str(), ppropvar); } if (key == UI_PKEY_ItemImage) { return UIInitPropertyFromImage(UI_PKEY_ItemImage, _image, ppropvar); } return E_NOTIMPL; } STDMETHODIMP CComboBoxtItem::Initialize(int value, CComPtr<IUIImage> image) { _value = value; _image = image; return S_OK; }

13. Right-click the Superscope Super1 folder and then select Delete. A message box appears indicating that only the superscope and not the child scopes will be deleted. 14. Click Yes. 15. JIn the DHCP console, right-click the Scope [192.168.1.0] Test Scope 2 folder, and then select Delete. A message box appears asking you to confirm the deletion. 16. Click Yes. 17. Close the DHCP console. 18. Log off Computer1.

The location of routers, and all services that they provide, as well as firewalls and proxy servers. This will assist you in securing DNS resources. Later, you will see how a router or firewall can filter traffic on particular ports to increase security. Next, you should review the document information for each subnet on the network you created. If you recall, this document described the network identity (ID), subnet mask, and ranges of hosts on the subnet, DHCP, and DNS configura tions. This can be used to determine the amount of users on the network or in a particular location, and will help in your DNS server placement.

If these security action names are confusing, the problem is not you. Why is a declaration called RequestMinimum if it s actually a requirement The name RequestMinimum sounds like your code is politely asking for permissions. Given the way RequestMinimum behaves, it should be called RequireMinimum because the runtime doesn t respond nicely to a request for permissions that it can t provide it throws an exception and refuses to run your assembly. Also, the runtime will never grant your code permissions that the code wouldn t have had anyway. RequestOptional should actually be called RefuseAllExcept because the primary purpose is to explicitly list only those CAS permissions your application should have.

5. Click Advanced, and then select the Auditing tab. Add your user account to audit List Folder / Read Data: Failed, and then click OK to close all Property dialog boxes. 6. Double-click the Data folder to open it. You should receive an Access Denied warning message.

In this exercise, you simulate a data loss incident by deleting the .mdf file associated with the MyDB database. (To delete this database file, you must first stop the local instance of SQL Server.) After you delete this database file, you back up the tail of the transaction log.
