Meaning of computer security (what is it, concept and definition)

What is Computer Security:

Computer security is a set of tools, procedures, and strategies that aim to guarantee the integrity, availability, and confidentiality of an entity's information in a system.

Computer security is characterized by the protection of data and communications on a network ensuring, as far as possible, the three basic principles:

• The integrity of the data: the modification of any type of information must be known and authorized by the author or entity. System availability: continuous operation to maintain the productivity and credibility of the company. Confidentiality: data disclosure must be authorized and data protected against attacks that violate this principle.

Computer security is a discipline or branch of Information Technology that studies and implements threats and vulnerabilities of computer systems, especially on the network, such as viruses, worms, Trojan horses, cyber attacks, attacks of invasion, identity theft, data theft, password guessing, interception of electronic communications, among others.

Types of computer security

Computer security is usually divided into three classes:

Hardware security

Hardware security involves both physical protection and traffic control of a network and constant scanning of a system. Some examples of hardware computer security are hardware firewalls, proxy servers and cryptographic keys to encrypt, decrypt and authenticate systems, backups, battery banks for power outages, etc.

Software security

Software security is dedicated to blocking and preventing malicious attacks by hackers , for example. Software security is part of the process of implementing a program, the work of computer engineers, to prevent unauthorized modifications that cause the malfunction or violation of the intellectual property of the program itself.

Network security

Computer security on the network is applied through the hardware and software of the system. Network security protects the ease of use, reliability, integrity, and security of the network and data. Some components that help in this regard are: antivirus, antispyware , firewalls that block unauthorized access, virtual private networks (VPN) and intrusion prevention system (IPS).
