Data safety is always a must. With portable devices it gets even more important. Here are a few steps that one can take to make sure their iPhone/iPad/iPod touch is secure. While the guide says iPhone, you can apply many of these steps to other iOS devices, subject to feature availability.
PASSCODE & TOUCH ID UNLOCK
This is the simplest form of security. You are prompted to setup your passcode during the initial device setup itself. While it is not necessary, it is highly recommended. Of course, you can change this at any time. The other option on the newer devices is to use the fingerprint scanner called Touch ID. This adds a convenience to the user while taking care of the security needs. The important thing is that your finger print details are left on the device. Nothing is shared over the internet. The Touch ID is limited to newer devices.
Activation lock is a feature that was first introduced in iOS 7. The idea behind Activation lock is to make sure that no one is able to use a stolen device, even if it is erased. This is activated automatically once you sign into your iCloud account. To use a device after it has been erased, the user must enter the Apple ID & password that was used to sign into iCloud on the device.

FIND MY IPHONE
This feature is available via the iCloud service. It allows you to locate your device & shows it up on the map itself. This feature is extremely useful if you have lost the device. Note: For this to work, the device requires an active network connection.
Another useful option is to automatically erase the phone, if the number of passcode attempts by a user exceeds the maximum specified limit.
This is setup in the Touch ID & Passcode section within the Settings app.
ALLOW ACCESS FOR SERVICES WHEN DEVICE IS LOCKED
Just having a passcode or Touch ID may not be enough in all cases. Some data is also available from the lock screen. One can control the availability of data on the lock screen from the Touch ID & Passcode screen within the Settings app.
Additionally, you can also control what information from your device is being shared & which apps have access to that information. There is a lot of flexibility available when it comes to controlling the kind of information being shared.
The user can specify which apps can access their contacts, calendar events, location & other data.
It’s very rare that one leaves their iPhone unattended. But in the rare cases that one is distracted from the task they are performing on the device, it would be nice to know if the device can lock itself up.
This is done through auto lock within the General settings under the settings app.
Located under the general settings within the settings app, restrictions, as the name says, allows us to disable certain applications and actions from being executed.
The passcode is required to enable/disable the feature.
