“What is networking and security?” Computer users are most familiar with the importance of having a network security system, but others may not even know why it is important to have it. Network security is software installed on your computer at the time of manufacture. It is important for your computer because it protects your computer from hackers, viruses or other malicious software that could damage it. Even though network security is not a necessity for computers, it still protects you and your computer from numerous viruses, worms, or even hackers that could easily penetrate your software. Computer security is the prevention and detection of unauthorized computer use. Prevention prevents intruders from accessing parts of the computer system. Detection determines whether someone is trying to break into your system, whether they succeeded, and what they did to your system (Carnegie Mellon University np). It is actually very easy for an intruder to break into your computer. Unfortunately, hackers are always finding new ways to break into people's computer systems. When "holes" are found, vendors will create patches to fix the problem, but it is up to the user to download and install the patch or configure the computer system to operate securely (Carnegie Mellon University np). Hackers probably don't really care about your identity. Most likely they just want to have control over your system so they can use it to hack other systems. Hacking your computer allows them to hide their location from high-profile systems like the government and banks. Even if you are on the Internet to play games or listen to music, your computer can still be hacked. Hackers find themselves in the middle of the paper and boot properly. It is caused by incorrectly shutting down the PC, closing a running program, using malicious software or freeware, but also by power outages and especially by file corruption after the hard drive becomes unstable and stops working properly (Creative Team np); The last reason for most hard drive failures and probably the most effective is human errors, which are mostly due to human errors and can cause damage to the system. Changing system registry files, altering attributes file or any other can cause a lot of damage to your PC. These errors are difficult to recover and require the most powerful hardware recovery software to scan and recover important data thoroughly (Creative Team np). In conclusion, the importance of network security is to maintain the reliability, integrity, usability and security of data on a network or personal computer.
