How to protect your computer
Cybercrime prevention can be straight-forward - when armed with a
little technical advice and common sense, many attacks can be
avoided. In general, online criminals are trying to make their money as
quickly and easily as possible. The more difficult you make their job,
the more likely they are to leave you alone and move on to an easier
target. The tips below provide basic information on how you can
prevent online fraud.
Keep your computer current with the latest patches and updates
One of the best ways to keep attackers away from your computer is to
apply patches and other software fixes when they become available.
By regularly updating your computer, you block attackers from being
able to take advantage of software flaws (vulnerabilities) that they
could otherwise use to break into your system.
While keeping your computer up-to-date will not protect you from all
attacks, it makes it much more difficult for hackers to gain access to
your system, blocks many basic and automated attacks completely,
and might be enough to discourage less-determined attackers, so
they will give up and look for a more vulnerable computer elsewhere.
More recent versions of Microsoft Windows and other popular
software can be configured to download and apply updates
automatically so that you do not have to remember to check for the
latest software. Taking advantage of auto-update features in your
software is a great start toward keeping yourself safe online.
Protect your computer with security software
Several types of security software are necessary for basic online
security. Security software essentials include firewall and antivirus
programs. A firewall is usually your computer's first line of defense-it
controls who and what can communicate with your computer online.
You could think of a firewall as a sort of "policeman" that watches all
the data attempting to flow in and out of your computer on the
Internet, allowing communications that it knows are safe and blocking
"bad" traffic such as attacks from ever reaching your computer.
