How to

Shore up your Mac’s se­cu­rity

APC Australia - - Superguide Security On Mac And Ios -

1 DIS­ABLE FILE SHAR­ING

It can be use­ful to be able to share files, print­ers, screens and other fea­tures while at home, but you should dis­able them in Sys­tem Pref­er­ences’ Shar­ing pane when us­ing your MacBook on other net­works.

2 EN­CRYPT THE DISK

En­crypt­ing your Mac’s stor­age pre­vents any­one else from ac­cess­ing its contents. Go to ‘Sys­tem Pref­er­ences > Se­cu­rity & Pri­vacy > FileVault’ and click ‘Turn on FileVault’ — your Mac is then en­crypted even as you use it.

3 SA­FARI EX­TEN­SIONS

There are great ex­ten­sions for Sa­fari, but some risky places on the in­ter­net to down­load them from. Stick with Ap­ple’s cu­rated col­lec­tion for safety: in Ap­ple’s web browser, choose ‘Sa­fari > Sa­fari Ex­ten­sions’.

4 FRAUD WARN­INGS

Sa­fari is able to warn you about un­safe web­sites be­fore you even go to them. Again with Sa­fari in the fore­ground, go to ‘Sa­fari > Pref­er­ences > Se­cu­rity’ and check the ‘Warn when vis­it­ing a fraud­u­lent web­site’ set­ting.

5 AVOID ‘SAFE’ FILES

Sa­fari can au­to­mat­i­cally open sup­pos­edly safe files af­ter down­load­ing them, which is con­ve­nient for you but also for mal­ware. In Sa­fari’s Gen­eral pref­er­ences, clear the check­box next to the cor­re­spond­ing op­tion here.

6 AVOID JAVA

Java has been re­ported to have been used by mal­ware au­thors for years. Only in­stall it if ab­so­lutely re­quired. See ap­ple.co/2hMBdgF re­gard­ing the browser plugin, and bit.ly/2rqgP99 for unin­stal­la­tion steps.

7 EMAIL AT­TACH­MENTS

Mal­ware can be dis­trib­uted through email at­tach­ments — and this isn’t just used to tar­get Win­dows PCs. Do not open or down­load files from emails un­less you know they are from a trusted source and safe.

8 WHERE TO GET APPS

The Mac App Store is the safest place to get Mac soft­ware, as Ap­ple vets what’s fea­tured. If you must get an app from else­where, use its devel­oper’s pub­lished check­sum to ver­ify the file is un­al­tered — see bit.ly/2rVu1q3.

9 AVOID LINKS IN EMAIL

Phishing tries to trick you into re­veal­ing de­tails of your Ap­ple ID, bank, PayPal and other ac­counts. Treat emails ask­ing for lo­gin de­tails with sus­pi­cion and don’t click links. If in doubt, go to a site’s ad­dress man­u­ally.
