Cybersecurity involves protecting computers and networks from malware and hackers while maintaining privacy. Physical and digital factors are considered, including physical access security, operating system security, data integrity, network access, and intrusion. Encryption, strong passwords, and antivirus software are necessary.
Cybersecurity involves protecting computers and networks from malware, hackers, and other threats while maintaining privacy on the Internet and on physical networks and systems. Both physical and digital factors are considered, as both can compromise the integrity of a system. Key areas covered include physical access security, operating system security, data integrity and protection, network access and intrusion. The goal of computer security is to reduce these risks as much as possible and to use countermeasures to fix security problems as quickly as possible.
Physical access is one of the most critical factors in protecting computer systems and networks. Even if you take steps to encrypt your data and block network access, these will be useless if someone steals your physical system or gains direct access to it. Physical security involves protecting the building that contains your computer using special doors, identification processes, and security cameras. It also involves training employees not to give their passwords to strangers and to recognize social engineering techniques.
Operating system security is another important factor in computer security. If an attacker gains control of a person’s computer, he can control the victim’s operating system, steal data and destroy important information. Security holes are found in the most common operating systems, so vendors periodically release patches that users can install to better protect their systems. Viruses and spyware also pose a risk to many operating systems, so antivirus protection software is needed to prevent data loss and unauthorized access. If a computer is in an area with many people around, users should also use strong passwords to prevent unauthorized users from making changes or reading sensitive data on their computers.
Computer hard drives, optical media, and flash storage often contain personal information, so computer security emphasizes protecting these items with encryption that enhances data security by making it unreadable to unauthorized parties. Many operating systems have features that can encrypt individual files or entire hard drives. There is special hardware available that can encrypt your data even when you log on to a different computer.
Securing computer networks is critical to computer security. Hackers who find information on a company’s network can use tools to gain access to other computers and servers. A firewall helps block access to the network and can be configured to various levels of security. Wireless networks also have encryption features that can protect your data and prevent unauthorized access to your network.
