iPhone 4S Security

The release of the iPhone 4S caused quite a stir because it was not what everyone was expecting. Many of the pundits were boldly pontificating about advanced new features that would be introduced via “iPhone 5″. Instead they got the iPhone 4S which didn’t match expectations but it has been a pre-order bonanza anyway. It seems Apple can literally do no wrong right now. I decided to order an iPhone 4S (32GB memory black model) and hope to get it towards the end of the month.

When it comes to securing your iPhone 4S not a lot has changed at this point. The iOS 5 update is expected very soon which will likely introduce some security changes worth mentioning so I will provide an update when that hits the street.

Basics of iPhone 4S Security steps:

Set a private pass code to prevent others from accessing your iPhone 4S. If you do not set up a password you are at a bigger risk of having someone snoop or send prank texts/emails from your phone. Remember your code because if you forget you must do a restore.

Select General > Passcode Lock and enter your 4 digit passcode

Set password expiration parameter (which defines how long iPhone 4S will remain unused before pass code needs to be entered). A setting of 30-60 is a good idea.

Select General > Passcode Lock> Require Passcode then select the value you want

Disable Bluetooth if you do not use it. Bluetooth related vulnerabilities have gone from theoretical to actual problems being exploited so if you are not using it definitely turn it off.

Select General > Network and turn Bluetooth off

Set a voice mail password to prevent busy bodies or sleazy European tabloids from accessing your voice messages. Select a pin that will be easy for you to remember but not easily guessable by others (same concept as your debit card pin)

Select phone > Change Voicemail Password

Lock your SIM card to secure your sensitive information located in memory.

Select phone > SIM PIN and turn it on. The manual mentions the default iPhone SIM PIN is 1111 unless the carrier has changed it.

Backup your phone data every few months so that you will not lose your phone lists, pictures and other customized settings. This will be useful if an update goes wrong and your phone requires a total restore.

Install iOS firmware updates when they become available. iOS 5.0 is expected very soon and will contain new functionality and security fixesThe 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.

Only join WiFi networks that you trust or you risk having your information intercepted and possible identity theft.

Use Find My iPhoneFind My iPhone is Apple’s free app that helps recover or remotely wipe your iPhone 4S if you lose it or it gets stolen.

You also have the option for installing additional security applications to provide anti-virus and password related functions. If you are interested in additional security applications for your iPhone 4S be sure to review the best of itunes security store post.
