Controls automatic log-out of a user account. Lets you specify whether location-based services have access to your Mac's location data. The Mac Security preference pane has three tabs along the top of the window. Select the General tab to get started with configuring your Mac's general security settings.
Change Security / Permission Settings
The General section of the Security preference pane controls a number of basic but important security settings for your Mac. In this guide, we will show you what each setting does, and how to make changes to the settings. You can then decide if you need the security enhancements available from the Security preference pane.
If you share your Mac with others, or your Mac is located in a place where others can easily gain access to it, you may wish to make some changes to these settings. You will be prompted for an administrator username and password.
Provide the requested information, and then click OK. The lock icon will change to an unlocked state. You're now ready to make any changes you wish.

Require password: If you place a checkmark here, then you or anyone who attempts to use your Mac will be required to provide the password for the current account in order to exit sleep or an active screen saver. This is a good basic security measure that can keep prying eyes from seeing what you're currently working on, or accessing your user account data.
If you select this option, you can then use the drop-down menu to select a time interval before the password is required. I suggest selecting an interval long enough that you can exit a sleep or screen saver session that starts unexpectedly, without needing to provide a password. Five seconds or 1 minute are good choices. Disable automatic login: This option requires users to authenticate their identity with their password anytime they log on.
Require a password to unlock each System Preferences pane: With this option selected, users must provide their account ID and password anytime they attempt to make a change to any secure system preference. Normally, the first authentication unlocks all secure system preferences.
Log out after xx minutes of inactivity: This option lets you select a set amount of idle time after which the currently logged-in account will be automatically logged out. Use secure virtual memory: Selecting this option will force any RAM data written to your hard drive to be first encrypted. This applies to both virtual memory usage and Sleep mode when the contents of RAM are written to your hard drive. Disable Location Services: Selecting this option will prevent your Mac from providing location data to any application that requests the information.
Disable remote control infrared receiver: If your Mac is equipped with an IR receiver, this option will turn the receiver off, preventing any IR device from sending commands to your Mac. FileVault uses a bit AES encryption scheme to protect your user data from prying eyes.
Encrypting your home folder makes it nearly impossible for anyone to access any user data on your Mac without your account name and password.
We would love your feedback!
FileVault can be very handy for those with portable Macs who are concerned about loss or theft. When FileVault is enabled, your home folder becomes an encrypted disk image that is mounted for access after you log in.

When you log off, shut down, or sleep, the home folder image is unmounted and is no longer available. When you first enable FileVault, you may find the encryption process can take a very long time.
Can’t find what you’re looking for?
Your Mac is converting all of your home folder data into the encrypted disk image. Once the encryption process is complete, your Mac will encrypt and decrypt individual files as needed, on the fly. This results in only a very slight performance penalty, one that you will rarely notice except when accessing very large files. Set Master Password: The master password is a fail-safe. It allows you to reset your user password in the event you forget your login information. Customize Your Password Settings: Entering your password every time you boot up your Mac or open your laptop can be an annoyance, but it helps keep your information safe in case your computer falls into the wrong hands.
Set a password, change your password to make it more secure, or tell your computer when to require a password. For the latter setting, locking your computer immediately after the screen goes to sleep is the smartest option—particularly if you travel a lot or use this computer at work.
When FileVault is switched on, every file on your startup drive is encrypted and cannot be accessed or recovered without the password. When you turn on FileVault, you will be issued a recovery key to help you access your files if you should forget your password. Check for Operating System Updates: Apple keeps OS X pretty well updated—whether with small security updates to fix bugs or vulnerabilities, or with larger annual updates that change the look, feel, and features of OS X.
For the best security possible, always update your Mac as soon as new OS X updates are released. If the App Store says you have updates available, install them. This rule holds true for individual app updates, as well. Keeping these factors in mind is just the first chapter of protecting your Mac from threats.
