Computer, Internet, Network Security Tips


The following are some security measures that you need to pay special attention to it:

1. Physical security

This security measure is often overlooked because people do not think that this is a risk but actually it is. Anyone who has access to the computer can try and find out the password of your computer.

2. Learn your System

It is important to know something about your networks, printers, routers, hubs, and computer workstations that make up your current computer configuration around you. If you know these aspects, you will know what services need to be turned on and what services need to be turned off for the security reasons.

3. Make a list of all hardware and software

A detailed list all hardware and software will not only document your equipment, but it will also serve to document all systems and software that must be protected and maintained. The list will be very useful when the need for implementing upgrades, patches, and maintenance comes around.

A few things to keep in mind when checking your email is to never open attachments that you receive in your inbox. If you receive a attachment from your friends, check with them to make sure that they did send it to you before you open it and use your antivirus software to scan incoming e-mail before opening it. Email Attachments are the big cause of your computer infected!

5. Make backups of all-important data

Making regular backups and testing of the backups of all the data is very important because you never know when you will have a hard drive failure and have no chance of getting the data back unless you send it to people who Specialize in data recovery, but it will be very expensive.

6. Secure your backup data

Backups should be placed in a fire proof safe in a locked room or in another safe location with very few people having access to it. It is suggested that the same data should be stored in two different location. Any old backups that are no longer needed should be destroyed.

Encryption should be used when sending or storing documents on your harddrive and through e-mail that you doní»t want unauthorized people to view.

If you want to give your hard drive to others, you need to wipe clean of all your data. If you want to be sure that the data contained on the drives is "Completely" gone, you should destroy the platters in the hard drive if the drives are not going to be reused because others can easily recover the data you deleted, even if you did the reformation.

Cd and dvd backups should be kept in a saft place. If you do not want them, you need to shred them so that nobody else can get the data from it.

Using a bios password, you can prevent the computer from booting up. If you decide to use a bios password, check to see if your motherboard has the option to reset it by changing a jumper setting on the board. If not, you will have to use a program that will either clear it or show you what the password is. But keep in mind that this woní»t prevent someone from getting data out of your computer.

These accounts should have some security settings that prevent programs from being installed the user account should be used for everyday tasks such as checking e-mail, surfing the web etc there is less chance of messing something up when you use a user account.
