PC Security Issues
Personal Computers are very vulnerable to incidents which may cause damage to the equipment and destruction or loss of data stored on hard disks and diskettes. Typically these include: power problems such as loss of power, power fluctuations and static electricity; viral infections; and theft of equipment.
- If your PC is equipped with a lock, always lock it before leaving for the day.
- Save work-in-progress in case of power or equipment failure.
- Backup data regularly, at least once a week.
- Store all of the backup copies of your data in a secure place, such as a locking cabinet away from your workstation, or a Data Safe (this is a safe especially designed to protect diskettes against destruction from heat, smoke particles and humidity.) Backup copies of data should be stored off-site if practical.
- Backup your disk and then remove all sensitive or confidential data from the hard disk before sending hardware off-site for maintenance.
- Do not use illegal copies or pirated copies of software. Use only purchased or licensed software.
- Make sure that any diskettes you bring into the environment are free of computer viruses. Use a virus scan program before using the diskettes on your PC, especially if you are connected to a Local Area Network.
- Use a power bar or other similar equipment with surge protection to protect your equipment and data against losses caused by sudden power fluctuations.
- If you experience static electricity problems in your office, install an anti static device such as an anti static mat and touch the mat BEFORE you touch your keyboard or computer.
- If you use your PC to create and process sensitive or confidential data, consider installing access controls software to prevent unauthorized access to your PC.
- Remove all sensitive or confidential data from diskettes before discarding them or using them again for storing new information. Use a utility like Norton "Wipe" to securely erase the data from diskettes.
- If your PC is connected to a Local Area Network or the mainframe computer, always remember to logout before leaving your workstation.
CARING FOR AND PROTECTING YOUR DISKETTES
It is quite easy to damage diskettes or to lose the data stored on them. Therefore it is very important that you use them properly and take proper care of them.
- Do not leave diskettes lying around. When you are finished with them, lock them away.
- Keep diskettes away from extreme low temperatures and from sources of heat such as radiators, direct sunlight, etc.
- Always store diskettes in their protective jacket.
- Never touch the magnetic surface of the diskette.
- Do not bend the diskette or use paper clips to attach it to paper documents.
- Keep diskettes away from magnets or equipment which produces magnetic fields (such as magnetic paper-clip holders, magnetic paper holders, electric pencil sharpeners, etc.)
- Use a felt-tip pen to write on diskette labels. Never use a pencil or a ball-point pen. Better still, write out the label before sticking it on the diskette and replace the existing label.
- Be careful when inserting the diskette into the drive so as not to damage the diskette or the drive.
