10 Precautions for computer network security

This is a guest post by John Clarkson. If you are interested to guest post in this blog, just head over to the Guest Post Guidelines.


There are a lot of precautions that a person must take to ensure the security of their computer network.

  • The first precaution is to have an antivirus program installed on your computer. This is so that the program can scan for any viruses on your files within the computer.
  • The second precaution is to install a firewall. The firewall is going to help a person’s computer from being hacked by other people. It can also find viruses called worms that usually will fall through the loopholes of all of the types of antivirus programs that you have installed on your computer.
  • The third precaution is to be very careful when you are opening an email. If you do not know who send the email or an email looks a little strange to you, then just delete it instead of opening it. This is especially true if the email has an attached file on it.
  • The fourth precaution is to be very careful about the personal information that you are putting over the Internet. When you are entering your personal information into a website, make sure that the website is very secure before you do so or only use well known websites.
  • The fifth precaution is to only get your downloadable programs from websites that are very well known. When you have downloaded the program, then you need to save them on your hard drive so that your antivirus program can check them. It is very important that you do not open the programs directly.
  • The sixth precaution is to use a password that only you are going to know. This means that a person should never use a name or a birthday as a password. The best thing to do is to use a combination of letters and numbers and change it every once in a while.
  • The seventh precaution is to make sure that you have activated the encryption key on your wireless network. This is because if you do not have a password on your wireless network, then other people can use your wireless network at their home. This means that they could also hack into your computer where your personal information could be displayed.
  • The eighth precaution is to make sure that you cut off your computer when you are not using it. This means that the computer cannot be connected to the computer without you being around it.
  • The ninth precaution is to be being aware if you get a warning that you have a virus on your computer. Unless you have run the antivirus program, then you should not get this warning. If you get this warning, it is going to tell you to delete a certain file that you might need in order for your computer to work properly.
  • The tenth precaution is to install all of the security updates, if your software program allows for you to update it every once in a while. This means that a person should also update their operating system when they have a chance.

    People fails to follow the last precautions. As far as i am concerned, updating the software is most important. Most of the malware exploits the known vulnerability in softwares.
