What is computer security?
Computer security includes computers and network protection against malware, hackers and other threats while maintaining privacy on the Internet and on physical systems and networks. Physical and digital factors are considered as it can either endanger the integrity of the system. The main areas include physical access, operating system security, integrity and data protection and access and network. The aim of computer security is to reduce these risks as much as possible and use countermeasures to repair security problems as quickly as possible. Even if one takes action to encrypt data and block access to the network, it will be unnecessary if someone steals a physical system or gets direct access to it. Physical security involves securing a building containing a computer using special doors, identification processes and security cameras. It also offers employees training to give their slogans to foreigners and recognize social engineering techniques.
Operating system security is another important factor in your computer security. If an attacker gains control of a human computer, he can control the victim's operating system, steal data and destroy important information. The safety holes are found in most common operating systems, so suppliers regularly release patches that users can install to better secure their systems. Viruses and spyware also pose a risk for many operating systems, so it is necessary to protect viruses to prevent data loss and unauthorized access. If a computer is in an area with many people around it, users should also use complex passwords to prevent unauthorized users from making changes or reading sensitive data on their computers.
Computer hard drives, optical media and flash storage often contains personal data, so the security of the computer emphasizes the protection of these items by encryptRé improves data security by being unreadable to unauthorized parties. Many operating systems have functions that can encrypt individual files or entire hard drives. There is a special hardware that can encrypt data, even if there is access to another computer.
PC security networking is crucial for security of the computer. Hackers who find the company's network can use tools to get access to other computers and servers. Firewall helps block network access and can be configured to different security levels. Wireless networks also have encryption functions that can protect data and prevent unauthorized network access.
