The iPhone has been easily winning the battle vs. Google Android and other mobile devices for market share but is it leading the pack in security? Out of the box the iPhone has some security gaps but if you follow these iPhone security tips you will be ahead of the game in protecting your device.
iPhone Security Settings
1. Set up a pass code to help prevent unauthorized use of your iPhone. By default no password is required but that kind of setup greatly increases the chances of someone snooping on your phone (the most probable scenario) if you leave it unattended or if it gets lost. If you forget your pass code you must do a restore so be sure to remember it.
Select General > Passcode Lock and enter your 4 digit passcode
2. Set how long before passcode is required (how long iPhone can be locked before passcode needs to be entered). A setting of 30 minutes should be good here.
Select General > Passcode Lock> Require Passcode then select the value you desire
3. Disable Bluetooth if you do not plan to utilize it. If Bluetooth is active it is another potential vulnerability source so if you are not using it shut it off.
Select General > Network and turn Bluetooth off
4. Set your voicemail password to prevent others from accessing your voice messages. Select a pin that will be easy for you to remember but not easily guessable by others (much like your ATM pin)
Select phone > Change Voicemail Password
5. Lock your SIM card to help provide additional security around your sensitive information.
Select phone > SIM PIN and turn it on. The manual mentions the default iPhone SIM PIN is 1111 unless the carrier has changed it.
6. Turn Pop Up Blocker On to enhance security and browsing experience (note that this stops only entry/exit induced pop ups not click through pop ups)
Change security settings: Choose Safari, then turn pop up blocker on
7. Backup your phone data periodically so that you will not lose your phone lists and other customized settings. This will come in handy if a firmware update ever goes haywire.
8. Install iPhone firmware updates when they become available. The recent passcode bypass vulnerability will be updated in a November update and in general when hardware or software is updated by a vendor it is often is due to security vulnerabilities so it is best to stay current with these important updates.
9. Only join WiFi networks that you trust to lower your chances of having passwords and other sensitive data intercepted by those seeking to steal your credentials.
