The most basic options are perfect for those who don't have much personal information on their device, and just want a quick way to secure their stuff.
The easiest is to set up a screen lock in Settings > Lock Screen > Screen Lock. There is a range of options here, offering low-, medium- and high-security levels.
At the lowest level you can use Face Unlock or Face and Voice Unlock, using the front-facing 1.9MP camera to recognise your face and unlock the handset.
The next step up involves setting up a security pattern, which you draw onto the screen for access, or a PIN of between four and 16 digits, which you'll need to enter each time you unlock the phone.
The highest level of lock screen security comes in the form of an alphanumeric password, allowing you to use numbers and letters to create a unique identifier, up to 16 characters long.
You can also set up Auto Lock from the Screen Lock menu, which will lock the Note II after a set period of inactivity – perfect if you're the sort of person who leaves their phone lying around without hitting the lock key.
If the information you have stored on your GALAXY Note II is of a more sensitive nature, such as work emails, Samsung also offers a range of more advanced security options to put your mind at rest.
Navigate to Settings > Security, and you'll find several options to help you secure your Note II further.
The first of these is Encryption, which encodes all the information on your handset and requires a password every time you turn the Note II on in order to decipher it.
If you're using a microSD card in the phone, you can encrypt that too, ensuring a fully secured setup.
If you're worried about losing your phone, Samsung also has an excellent remote control system, which allows you to track, ring, lock and even wipe your phone remotely from a web browser.
To set it up, just sign in to your Samsung account online (it's easy to register if you don't have one already) and turn on Remote Control. Then head to the Samsung Dive site to control your GALAXY Note II remotely.
There's also an option to set up a four-digit PIN code on the microSIM, which you'll be asked to enter every time you switch on your GALAXY Note II.
Staying safe online
Whether you use the web through a smartphone, a tablet, or at a good old-fashioned desktop, you need to be careful about how much information you share online.
To set your privacy options on the Note II, open the internet browser and hit the menu button below the screen. Then navigate to Settings > Privacy & Settings to manage your cookies, form data and location settings, as well as your browsing history.
For the highest levels of online security, the Note II also has an incognito mode, which doesn't store browsing history or cookies on the device at all.
