Top 10 User Wi-Fi
Safeguards
Your users are your first line of defense.
They need to play an active role in helping to
protect information systems. Listed below are
the Top 10 steps they can take when using wireless
networks.
- Signal strength. In general,
the closer the user is to the access point, the
stronger the signal and the faster the transfer
rate. Rogue (unauthorized) access points
may or may not be in the same facility as
authorized devices. Users should know that
signal strength alone, is not sufficient to
determine authorized networks.
- Manual connection. Portable
devices such as laptops and handhelds should be
configured so that they do not automatically
connect to wireless networks. A manual
process helps ensure that the device connects to
the appropriate wireless network.
- Legitimate network. Since Wi-Fi
signals can travel a long distance, users should
check with the management of the facility that
provides the connectivity to ensure they are
connecting to the appropriate network.
Unauthorized "evil twin" networks can capture
logon credentials and other sensitive
information.
- Encryption. There are many
different types of encryption methods used to
secure wireless networks. Wired Equivalent
Privacy (WEP) is the oldest and least preferred.
Wi-Fi Protected Access (WPA) is newer and offers
better protection. WPA2 is the newest and
should be used if possible. Users should
use Virtual Private Network (VPN) when
connecting to corporate systems.
- Shoulder surfing. Ensure that others
cannot obtain the user's ID and password as it
is typed. In addition, sensitive
information should not be able to be read on the
screen by unauthorized personnel.
- Screen aware Users should look
at the address bar URL. This will help
protect against phishing attacks. Secure
pages typically have a URL starting with https
and include a secure page notification such as a
lock.
- Firewalls. Firewalls help restrict
traffic to and from the device. Users
should ensure the firewall is turned on so it
can actively protect the device.
- Patch management. Users should
ensure that operating system and security
protection software is patched and up-to-date.
Ensure browsers and updates to third party
software packages are applied in a timely
manner. Critical updates should be tested
and applied as soon as possible.
- Battery saver. Portable devices
constantly search for available networks.
Users can increase battery life by turning off
Wi-Fi when it isn't needed. This also
helps ensure that an intruder can't connect to
the device.
- Incident management. Users should
inform the appropriate personnel if they believe
they logged into the wrong network, sensitive
information such as their ID/password was
compromised, their device was lost or stolen,
etc.
Risk assessments
help organizations identify, manage, and reduce
their risks related to mobile computing devices and
communicating with wireless networks.
