Now it's the time to secure your Mac from either data thieves or network hackers. These are the basic settings you can make to secure your Mac:
There are several things to be aware of when you're choosing options for your login items, such as disabling automatic login or hiding available usernames.
Here is the complete steps to secure your login:
If you have used your Mac for quite a long time, you'd prefer let your Mac sleep rather than shut it down when you're away. This is when securing sleeping Mac becomes essential. So you will need to set your Mac to ask for password whenever someone wakes your Mac up.
Here is how to set it:
Keychain login password is set by default the same as your account login password. So if somehow someone knows your password, that person will also know all passwords for your entire application, either it's IM or even your Mail.
Don't let this happen. The only way out is by differentiating your keychain and your Mac password. Here is how to do it:
But of course, the better solution is not to let strangers know your login password.
Before doing any changes to your Mac, your Mac will prompt a login window asking for your password. This is meant to give your more control over your account.
If you got window prompted asking your password out of the blue, don't give it out if you don't really know what's happening. Maybe it's a malware..
Most of the time, Apple will release patches for potential security issues. So make sure you check for updates daily. Or, you can have your Mac to check it daily for you:
There is something you need to take note, if there exists new version of your Mac OS X in Software Update List, make sure you check on forums to see whether any issues encountered during updating.
In Leopard, you can do screen sharing. This is a mixed blessing: You can share your screen as you want but also strangers can access and control your screen.
So you need to handle screen sharing permission: only to enable it with your permission. How to do it?
Firewall is turned on by your Mac default setting. But for the sake of completeness, maybe you are interested in applying Stealth Mode for your Mac: To make your Mac hidden beneath the wall.
The easiest way to make backup is by using feature introduced by Leopard: Time Machine. After setting backup drive for the first time, your Mac will automatically do the backup for you.
But if you choose to backup manually, you can use Carbon Copy Cloner and/or Super Duper as discussed in my earlier post: Make Mac Backup.
If your data can do harm to your business, you should consider turning on FileVault. With FileVault, your Home folder will be encrypted so that unauthorized users can't access those data.
So even though your Mac is stolen, the thieves cannot access your files. But be careful, if you lost your login password and master password, your data will be lost forever (as shown in the warning).
To turn on FileVault:
It's obvious, right?
One last thing, currently we got no virus on Mac, but who knows that someday some malevolent enterprises will create one. So my advise, keep up to date, especially on security issues, and stay low profile.
