Security
Quickies
“that
could save your bacon”
Choose a password that's
hard to crack When choosing a password, try to make it by writing a
sentence that you can easily remember. For example: "Los Angeles Lakers
will win the NBA tournament this year". Then pick up the first letters of
each word and also add at the beginning or at the end (or at both parts)
some special characters and numbers. For example, with the last sentence
you could get the password: =3LALwwtNtty$. This method lets you come up
with easy-to-remember passwords that are also hard to crack. And you avoid
the need to write such a long password down in order to remember
it.
Be careful with cybercafé
computers Cybercafés offer a convenient way to use a networked
computer when you are away from home or office, but be careful. It's
impossible for an ordinary user to tell what the state of their security
might be. Since anyone can use them for anything, they have probably been
exposed to viruses, worms, Trojans, keyloggers, and other nasty malware.
Should you use them at all? They're okay for casual web browsing, but
they're NOT okay for connecting to your email, which may contain personal
information; to any secure system, like the network or server at your
office, bank or credit union; or for shopping online.
Lock it when you leave
it Never leave your computer logged in when you walk away, not even
for a minute. Make it a habit to log off your workstation whenever you get
up. Remember to always leave your Windows computer by pressing the
keyboard shortcut combination of the Windows logo key and the letter "L"
on a Microsoft natural keyboard. Get it? Leave Windows by pressing the
Windows logo + L keys together to lock it up.
Secure your Wireless
Router When setting up a wireless network at home, I was surprised
to be able to connect to my neighbor's unsecured wireless router. Not only
could I have used his bandwidth for free, but had I been so inclined, I
could have used the connection for illegal activities. If the police came
looking, he may not have been able to prove the activity didn't come from
one of his computers. Properly securing wireless is not hard. Look in the
manual for changing the SSID to something unique, turning on WPA (avoid
WEP) for authentication and TKIP for encryption, and using MAC address
filtering.
You’ve heard
about Bluetooth, but how about Bluejacking, Bluesnarfing, and
Bluebugging? A study by
research firm InsightExpress has revealed that 73% of mobile device users
are not acquainted with security issues that could put at risk mobile
devices such as cellphones and Bluetooth-equipped notebooks. To these
users, terms such as bluejacking, bluesnarfing or even bluebugging would
probably be unfamiliar. Bluejacking, also known as bluespamming, is a
technique used to send anonymous text messages to mobile users via
Bluetooth. Bluesnarfing, a more dangerous technique, can allow a hacker to
access information stored on a mobile device without its user's knowledge.
Possibly the most serious of the three risks is bluebugging. This
technique allows attackers to access mobile-phone commands using Bluetooth
technology, without notifying or alerting the device owner, and initiate
phone calls, send and receive text messages, read and write phonebook
contacts, eavesdrop on phone conversations, and connect to the
Internet. More information:
