and work on all the devices used in your corporate network. In a
heterogeneous real-world infrastructure, because there may be a variety of
mobile devices from different vendors using different operating systems, a
one-size-fits-all anti-malware solution probably won’t work. Multiple
solutions may be necessary for the different devices present on a network, or
different modules covering specific types of device may be available from the
vendor to integrate with an enterprise-level anti-malware solution.
In any case, the most important part of an enterprise-level anti-malware
solution is delivering timely updates to the devices on a routine basis.
Network access-control solutions can ensure a device is checked for the latest
anti-malware signatures and updated as necessary when it attempts to connect
to the network. In the case of user-managed devices, you may need policy,
network access-control, and other technical solutions to ensure users are
updating their own devices in a timely manner.
Dealing with Loss
The best way to make sure you’re ready to survive losing a mobile device is
to assume it’s inevitable. Say it to yourself: every mobile device will get lost
at least once. I hope most of your users will prove you wrong, but the odds
are good we’ll all misplace every device we own at least once. Most of us
will be lucky and find it right where we left it, but it could just as easily go
the other way.
When you start with the assumption that your device will end up at the
mercy, kindness, or ignorance of strangers at least once, it’s obvious: you
should protect your data from access by putting a good passcode lock or
screen lock on the device. Most mobile devices enable you to set a passcode
lock or screen lock through Settings (see Figure 25-10). Do it right now!
There are many types of these locks; the most common require you to input a
password, PIN, pattern, fingerprint, or successful facial recognition to unlock
the mobile device so you can use it. Modern iOS and Android use full device
encryption to protect the built-in storage, so even a “finder” who dismantles
the device to access the drive will not get your documents.
