Cyber Security: Keeping The Bad Guys Out Of Your Network
As Internet use continually increases, so does the
potential security risk to our computer systems. It pays to know about how to
protect your network security, and how to stop hackers accessing your computer
systems. Here are the potential risks to your computer systems, and what you
should do to combat those risks:
What is cyber security?
Cyber security is the process of identifying
potential hazards and risks that are posed to your computer systems by the
Internet, and finding ways to counteract these hazards. Cyber security is
becoming increasingly important due to the large scope of the Internet, and the
information that we store on our computer systems. Protecting yourself from hackers
can stop problems such as identity theft, credit card fraud, and loss of
important data.
What are the risks?
These days there are many risks
to your computer systems, some of which are very serious. Among the main
dangers are having viruses erase your entire computer system, having files
altered or having your credit card or personal details stolen. Obviously, even
with the best prevention measures there is no guaranteeing that you will not be
a victim of these things, but it knowing about cyber security can greatly
reduce the risk of such problems.
What can you do?
Despite the increasing threat posed by hackers and other
malicious entities, there are a number of simple steps you can take to ensure network security. In
order to keep your computer systems safe you should:
Use a strong password
Make sure that any passwords
you use for access to the Internet or web based programs are strong and secure.
Many hackers use programs that contain millions of common passwords, and so by
using a weak password they will be able to gain access to your computer more
easily. A strong password should contain a minimum of 8 characters, with a mix
of both letters and numbers. If possible, try to avoid words that are in the
dictionary, and combine lower and upper case letters. For example, something
like 1dfgef$389 is much more secure than johnsmith123. Although harder to
remember, it will block one potential entry point to your computer systems.
Change passwords regularly
It is a good idea to change your passwords regularly,
with every 90 days being a good interval for change. By change the passwords
for your computer systems, it limits the damage that someone can do to you.
Even if they get a password, by the time they get around to using it, the
password will be outdated.
Have up-to-date virus protection
Most computer systems have anti-virus
software as standard, but if not then it is essential that you buy some. Norton
and McAfee are two of the most common programs used. As well as making sure you
have anti-virus software installed, you should also make sure that it is
up-to-date. Many programs have regular updates and patches that can be
downloaded which respond to new threats. Make sure that your software can
automatically update, or if not then regularly check for updates in order to
keep your software current and effective.
Be wary of emails
Emails are a common way to gain entry to information
on your computer, so you should be wary of any unknown emails you receive.
Although most email clients are equipped with anti-spam software, this software
will not catch all harmful messages. If you receive a message with an
attachment, even if it is from someone you know, then be careful. Make sure the
attachment is virus scanned before opening it. If you are in doubt, simply do
not open the email and delete it. It is much better to be cautious than to end
up opening an email that contains a virus or other malicious code.
Install a firewall
Firewalls are the perimeter defense for
your computer systems, and if you do
not already have one then it is a good idea to get one. Programs like windows
or anti-virus programs usually come with firewalls. However, the settings of
the firewall can be changed in accordance with what you want it to block or not
block. The higher you can put the setting without losing access to the things
you need the better your network
security will be.
Regularly assess your security
Once these measures are installed, you need to maintain
your security. Hackers find new ways to get around protection, and it is a good
idea to regularly assess your network security. If you keep savvy and vigilant,
then you can stop any problems before they occur.
Never share
information
If your computer is protected from intruders through
the Internet, make sure that it is equally protected in other ways. Do not give
your passwords out to anyone, and remember to properly dispose of any personal
information you have that could help someone gain access to your computer
systems.

Although
there is no guarantee that your computer will be 100% secure, by following
these simple steps you will make it much harder for anyone to access your computer
systems, and your information can remain private and safe.
