CYBER SECURITY ISSUES AND TIPS FOR COMPUTER SYSTEMS:
Physical computer security is the basic and most essential aspect of cyber security; it contains the security of the computer system in a tangible manner i.e. through virtual controls such as software protection and encryption etc. We are advising some of the basic and most essential physical computer security measures which can be adopted and followed to have a safe and secure system.
1. Check the computer for any physical plug-ins such as pen drives, key loggers etc attached to the system to gain your information by mischief. Such instruments are visible on the system if watched carefully. This must be carefully followed while using any common or public computer system like internet cafe, office systems etc.
2. Never leave your smartphones, computers, laptops, notebooks containing personal information unattended and unsecured for a while at any public place.
3. It is always safe to keep your external devices such as pen drive, external hard disk, USB sticks etc locked through some password on the connection. It may be a bit uneasy to operate but always safe especially in case you lose it, all your private date is protected.
4. Whenever your hard disk or memory is dead and not usable, be sure to dispose of them in a secured way, the best way is to destroy them physically by breaking as it rules out the chance of any data retrieval.
5. Always keep your WiFi in off mode when not in use, you can adjust the settings accordingly.
