Data Protection
Five major threats to the security
These are 5 major threats to the security of data held within a computer system:
- Theft
- Virus
- Spyware
- Media Failure
- Hacking/Unauthorized access
I’ll be talking about what is meant by them and how to prevent these issues from occurring in this project.
Virus
Viruses, these are programs that hijack the system and reproduce with the purpose of damaging and destroying the system. Many viruses attach themselves to executable files that may be part of legitimate programs. If a user attempts to launch an infected program, the virus' code may be executed simultaneously.
How they spread: Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer without the knowledge of the user. Can also gain a virus by connecting to the Internet and downloading an email message
Virus Prevention
Get good anti-virus software: Antivirus software is used to prevent, detect, and remove well basically any potentially dangerous and unwanted programs on your computer.
BEWARE OF ATTACHMENTS. Do not open email attachments you are not expecting: Email viruses and worms are common. Not opening an email from someone you know is the first step. You should only open email you’re expecting, you know it’s from a trusted sender and should always check if you have received an email from the sender before.
Installing a quality firewall: A firewall is a form of security system consisting of a combination of hardware and software that prevents unauthorized access or hacking into the computer system. It’s a must to have it on your computer.
Install an anti-spyware application: It’s also a good idea to install an anti-spyware application because you can never be too sure.
Spyware
- Spyware are software that obtains information from a user's computer without the user's knowledge or consent. Unlike viruses, spyware does not usually self-replicate.
- These programs can change your Web browser's home page or search page, or add additional components to your browser you don't need or want. They also make it very difficult for you to change your settings back to the way you had them.
- In most cases some spyware make changes to your computer that can be annoying and can cause your computer slow down or crash.
