One of the biggest threats to Mac computer users today is the belief that Apple’s operating system is immune to malware and viruse attacks. The Flashback Trojan attack (April 2012) was a strong reminder to Mac users that third-party software is a vehicle that can and will infect both Windows and Mac computers alike.
[Krebs on Security]: A year ago today, Apple released a software update to halt the spread of the Flashback worm, a malware strain that infected more than 650,000 Mac OS X systems using a vulnerability in Apple’s version of Java.
10 Ways To Protect Your Mac
1-Back-up-Sunday was World Backup Day - when was the last time you backed up your Mac?
With Apple’s Time Machine software (OS X 10.5 and above) you can perform full-system and incremental back-ups.
2-Use strong passwords: Check your password at Microsoft, is it strong?
A weak password such as 123456, password, abc123, or using your first name or pet’s name as your password is the Achilles heel of online security. Passwords are your first line of defense against cybercriminals. Create complex passwords for each site (do not share the same password at multiple sites), change them frequently and create accounts at sites that use good encryption.
3-Use a firewall & secure your Airport
A firewall is a barrier that can keep destructive forces (hackers, malicious software) from the Internet away from your computer.It can also stop your computer from sending malicious programs to other computers.
To set up the Mac OS X 10.6X and above Firewall:
Click the Apple menu > select System Preferences > select the Security Icon > Click the Firewall Tab > click the *Start Button > Advanced> select your desired Firewall configuration > click OK > close the security pane to save your selections.
* Note: If the Start button is gray, click the lock icon (bottom of window) and enter your administrative password at the prompt.
To secure your Airport:
Change your wireless router password to a strong password and use encryption.
4-Use Anti-virus software and keep it up-to-date.
New viruses and malware is created everyday, so it is important that you keep your antivirus software updated. Sophos Mac Home Addition (free for home users), is simple to install while updating and downloading virus definitions on an hourly basis.
5-Update OS X and Apps on a regular basis.
-Open software update from the Apple Menu to install updates.
-Open the App Store and download available updates.
6-Disable Automatic File Opening in Safari After Download.
For added security, disable this feature when using Safari > Open Safari Preferences > Click the General Tab > uncheck open safe files after downloading.
Note: If you use Cocoon, all files downloaded from the Internet require user approval.
7-Enable FileVault Encryption.
From the Apple Menu: Open System Preferences > Click on Security & Privacy > Click the FireVault Tab
8-Enable Anti-Malware Definitions
This should be enabled by default. Double-check your preferences to make sure that it is turned on:
From the Apple Menu: Open System Preferences > Click on Security & Privacy > General Tab > check Automatically update safe downloads list
9-Be responsible with social networking sites.
Social networking sites are rife with rogue apps and Internet scammers that often prey on user’s to spread their wares via permissions granted by the user. With a little education anyone can stay on top of the bad stuff and have a better Internet experience overall.
Subscribing to the Sophos Security Blog and FaceCrooks will keep you aware of the seedy and unsavory side of social media, along with providing great tips on how to stay safe online.
10-Use a layered approach when surfing the web.
When you browse the web it is easy to land on an unsavory site or get hit by a drive-by-download. Today, the virtual threat landscape needs more protection than an antivirus suite. Many exploits utilize 3rd party browser plugins (Flash, Adobe Reader) and if your operating system or browser has a vulnerability – it can easily become an open door that invites hackers in. Surfing with Cocoon on the web can add an extra layer of protection to secure your browsing experience.
By following the above 10 tips, you will be able to minimize the impact that hackers and malicious software can have on your Mac.
