This document provides a checklist for hardening an Android device with various security settings and recommendations. It suggests forgetting unused Wi-Fi networks, turning off location services and Bluetooth when not in use, limiting saved SMS/MMS messages, updating to the latest OS version, and not rooting or installing apps from untrusted sources. It also recommends enabling encryption, auto-lock, and the Android Device Manager for remote wiping a lost device. Additional security measures mentioned include disabling network notifications and form auto-fill, and showing security warnings for visited sites.

1. Google Android
Hardening Checklist

2. Forget Wi-fi Networks
By default, an Android device will remember and
automatically rejoin networks that it has previously
associated with.
…….but unauthenticated Wi-Fi network
may be spoofed and then automatically
joined.
Further….if previously joined network has a
common SSID, such as “test” or “sample”, the
device may encounter an untrusted instance of a
same-named Wi-Fi network and automatically join

3. Location Services allows installed applications and visited
websites the ability to request your current location.
Turn off Location Services
Once access is granted to an application, the
application may request the data again at any time
with no further notification to users

4. Limit the number of SMS
& MMS saved
For high security environments, limiting the number of SMS and
MMS messages saved per conversation thread may reduce the
likelihood and scope of information disclosure in the event the
device is lost or compromised.

5. The issue is that anyone can run a wireless hotspot
and, joining a poorly configured or insecure network
could allow a malicious user on that same network to
intercept, capture, and alter any network traffic sent
by a user.
Disable Network Notification
By default, Android devices will automatically present
a list of detected wireless networks from an icon in
the status bar that users may attempt to connect to
when no networks that have previously been
connected to are available.

6. Update Operating System
to the Latest version

7. Do not ROOT the device
One should understand that by rooting device, you
are taking on increased responsibility for securing
the device and protecting from malicious software.

8. Do not install Applications from Third
Party App Stores
Installing applications from other sources is riskier since
there is no way of knowing how the stores are
managed and whether or not the applications available in it
can be trusted to not be malicious in nature.

9. Enable Device Encryption
This protects the data stored on the device
from unauthorized access in the event that it
is lost or stolen.
When enabled, Android uses your passcode or
password to generate an encryption key that is
then used to encrypt the device.
This passcode/password is
then required every time the
device is powered on.

10. Disable 'Developer Options'
When enabled, it is possible to
completely control a device
through this interface.
Android provides a number of features
that allow developers to interact with the
device through the built-in USB
power/data port to change its behavior,
read and modify local storage, and issue
commands.

11. Use an Application/Service to
provide Remote Wipe functionality
Many third party applications provide this
functionality. Some options include Norton Mobile
Security, Wave Secure, Lookout, Security Shield, and
Theft Aware.

12. Enable Android Device Manager
Android Device Manager is a free service
provided by Google that allows users to track
and remotely lock or erase an Android device.
A free Google account is required to use this
service

13. Set a PIN and automatically lock the
device when it sleeps
A PIN (or a password) is more secure than a pattern as
patterns can be trivially observed by people around you and
there have been cases of using the fingerprint smudges on
devices to derive lock-screen patterns
Setting a PIN prevents casual unauthorized
access to a device.

14. This option automatically locks the
device after it has been inactive for
the specified amount of time.
Set Auto-lock Timeout

15. This feature controls
whether passwords
are displayed as they
are entered. Disabling
this feature increases
security by making it
harder for people in
close physical
proximity to learn
your passwords by
observing you interact
with your device.
Disable 'Make Passwords
Visible'

16. Android does not natively provide this
functionality, but there are a number of third
party applications, some of which were
mentioned earlier, which can.
Erase Data Upon Excessive
Passcode Failures
Since excessive passcode failures typically indicate the
device is out of your physical control, having the device
automatically erase may protect the confidentiality of
information stored on the device.

17. These warnings could indicate that
communications between your
computer and the site's server are not
secure.
Show Security Warnings
For Visited Sites
This feature will warn you of
common security problems,
such as invalid or expired SSL
certificates, affecting the web
sites you visit.

18. Automatically filling in web forms could result in the
unintentional disclosure of sensitive data to unauthorized
people.
Disable 'Form Auto-fill'

19. Bluetooth should be
enabled only when
it is actively being
used.
Turn Off Bluetooth When Not In Use

20. The slides only give out few
steps to Harden your
Android Device.
It takes a lot many
other things to secure
it further..perhaps
Google for that please.
