148 CHAPTER 8 LEOPARD SECURITY Figure 8-5. The password sheet allows you to enter a password into a new keychain item. NOTE Ten years ago, an eight-character password was considered strong. Today, that would be a minimum acceptable in most situations. As computing power increases, passwords become increasingly less effective, since as password lengths increase, it becomes increasingly hard to remember them, and therefore less practical. For this reason, a number of password alternatives have been developed, and are gaining in popularity. These alternatives may be used to complement a password system or eliminate passwords altogether. These alternatives include smart cards and other hardware authentication devices, and biometric security measures (such as fingerprint readers). When you choose to enter a secure note item to your keychain, the sheet that appears (Figure 8-6) asks for a name for your item and then includes a large text field for your note. If you intend to store lots of personal information in a keychain, you may want to create a keychain separate from your login keychain to store information; this is easily done by selecting File ➤ New Keychain... from the Keychain Access menu. Figure 8-6. The keychain sheet for entering a secure note item
Other Keychain Options There are a few other features associated with keychains that are available from the Keychain Access utility. These are described in the following sections. Keychain Passwords By default, your keychain password (the password you will need to unlock data such as passwords and notes in your keychain) is the same as your login password. This password can be changed for each keychain using the Edit ➤ Change Password for Keychain “keychain”... command. Keychain Settings The Edit ➤ Change Settings for Keychain “keychain”... menu item allows you to access some additional options for a particular keychain. These include the ability to lock your keychain after a certain amount of time, or when your computer goes to sleep (you will need to enter your keychain password each time you or an application attempt to access a locked keychain). This also provides an option to synchronize your keychain with .<strong>Mac</strong>, allowing you to share a keychain across multiple computers utilizing .<strong>Mac</strong>’s sync features. Keychain First Aid If your keychain gets mucked up to the point that it no longer functions correctly, the Keychain First Aid selection under the Keychain Access application menu can help solve a number of problems. Depending on what First Aid options are set in the Keychain Access utility’s preferences, running Keychain First Aid will rebuild your keychain file and reset most settings back to the defaults, including setting the keychain passwords back to the login password, and setting the login keychain back to the default keychain. Data Encryption: FileVault CHAPTER 8 LEOPARD SECURITY 149 While the keychain feature protects your passwords while keeping them easily accessible, File- Vault protects your data from others. FileVault, accessible from the FileVault tab in the Security System Preferences pane (Figure 8-7), encrypts the contents of your home folder, protecting them from anyone who attempts to access anything stored there. The first step in enabling FileVault is to choose a master password by selecting the Set Master Password button. This will open up a sheet (Figure 8-8) for you to enter a master password that can be used to decrypt any of your computer’s FileVaults. The reason for this is that if a user forgets their login password, then this master password can be used by an administrator to reset the user’s password, allowing them to regain access to their home data.
