The internet has positively transformed our lives in many ways. But it has also increased the number of possibilities for online threats and attacks. The best way to ensure your online safety is to learn about basic cybersecurity rules. This article, “What is Computer Security?” offers a straightforward, introductory discussion of computer security and its basic concepts.
What Is Computer Security?
Computer security is about making sure that computers and the information they contain are protected against damage, theft, or unauthorized access. It prevents unauthorized people from breaking into your computer and allows you to detect unauthorized access if it happens.
There are many forms of computer security that help protect information from unauthorized disclosure or theft, especially in businesses.
What Are the Types of Computer Security?
To understand computer security types, you need to consider what you're trying to protect. Here are some common types of security:
• Information Security: Protects information from unauthorized access, modification, or deletion.
• Application Security: Protects applications from cyber attacks by adding tools to reduce risks such as hacking or data leaks.
• Computer Security: Protects an individual computer to keep it updated and secure.
• Network Security: Protects the devices and networks that make computers work.
These terms can sound very alike, and sometimes are used interchangeably, but they mean different aspects of security.
Why Is Computer Security Important?
Computer security is important for keeping your information safe by ensuring the computer system functions correctly, is only used by the correct users, maintains privacy or confidentiality, ensures nothing has been altered in an unapproved way or what is called integrity, and maintains availability when needed.
What Parts of a Computer System Need Protection?
The following are the main parts of a computer system that need to be properly protected:
• Hardware: The physical or tangible parts of a computer system such as memory and hard drives.
• Firmware: Firmware is specific software that is built into hardware that allows it to function properly. While you may not see this, it is nevertheless very important.
The CIA Triad
Computer security includes three major aspects, called the CIA Triad:
• Confidentiality: This means that only authorized users have access to data;
• Integrity: The data can only be modified by authorized users;
• Availability: The data is available when needed, for authorized users.
Computer security is basically the protection of your information and computer parts in a way that keeps it running normally, while being protected from individuals or programs that you don't want to have access to or change.
