Mac computers are some of the most secure, experiencing much fewer cases of malware infection than their Windows counterparts. However, this is not to mean that they are malware-proof or that Mac users should go easy on computer security. There have been past cases where malware creators have successfully attacked Mac computers. Do not let your false sense of security prevent you from implementing the following Mac security tips.
1. Keep Up With Software Updates
Unpatched security vulnerabilities provide one of the easiest means of infiltration to malware. OS X on Macs checks for new software updates by default. To ensure that it is on, go to System Preferences. You can even change the Check for Updates settings to the most frequent option.
2. Only Install Software From Trustworthy Sources
In one of the latest Mac updates, you can use a feature called Gatekeeper to determine the source of the apps you install. There are three options: from the Mac App Store only, from the Mac App Store and signed developers, and from anywhere. The third option is one you should avoid, as it leaves your computer at a substantially higher risk of malware infection.
3. Use Keychain
You may already know how important it is to secure your data and accounts with strong passwords. But remembering all your passwords can be challenging, especially if you have designed them to be difficult to crack. Keychain is a Mac utilities feature that you can use to store passwords, certificates, and website or application authentication information.
4. Back Up Your System Onto an External Hard Drive
Though Apple's iCloud is a useful backup feature, it is not 100 percent safe. To guarantee your data's security, use the Time Machine feature on your Mac to back up the whole system to an external hard drive.
5. Install a Strong Firewall
Mac computers come with a built-in firewall. Apple disables it by default. Switch it on and ensure that you have modified the settings for maximum security. Even better, install a stronger firewall with an excellent Mac internet security guarantee. A good recommendation is Little Snitch. It keeps track of everything, including outgoing connections and websites that try to track you.
6. Install an Antivirus
With so many Mac antivirus software programs out there, there is no excuse for you not to have virus protection for Mac. This provides an additional layer of security.
7. Use the iCloud Remote Wipe Feature
If someone steals your computer, you can locate it once he or she reconnects it to a network. You can go a step further by using iCloud to wipe the computer remotely, thus ensuring that your data does not fall into the wrong hands.
8. Use FileVault 2 Encryption
If your computer contains extremely crucial information, encrypting it with FileVault 2 is a much safer option. It provides full-disk encryption, and it requires a password for anyone trying to access your data when your computer is off.
9. Remove or Turn Off Java and Flash
These two are popular entryways for malware attacks. Unless you need these two features, it is best to disable them.
10. Restrict System Access Using a Password
Set your system so that it requires a password to use it every time it comes out of sleep or a screen saver. This ensures that even if you leave for a few minutes, no one can access your computer.
