Irma D. Rutherford Physical security refers to the protection of people and hardware, programs, networks, and information from physical events and situations that could result in devastating losses or cause harm to a department, company, or even an entire organization. This covers protection against natural disasters, fire and robbery, elimination of terrorism, and fire.
Physical security is a crucial element of a security strategy. It is the foundation for a variety of security measures, like the security of data. Physical security is the term used to describe the protection of buildings and equipment (some software and data contained within) from vandalism, theft, natural disasters, human-made catastrophes, and accidental destruction (e.g., electric surges, extreme temperatures, and drips of coffee).
It required hard-working construction, appropriate emergency mobility, stable power supply, adequate climate control, and adequate security from intrusion. Risk assessment is a process that identifies the vulnerability of an organization. It may use the vulnerability report to determine the priority of the amount of resources needed. Every improvement to a security vulnerability typically provides more security than before. It will improve the system to the greatest extent that is possible and also keep a list of enhancements that are still required.
Physical threats to a computer system could result from the loss of the entire computer system, destruction of hardware, harm to computer software as well as theft of the computer system, vandalism, natural catastrophes such as fire, flood or war, earthquakes, etc. The terrorist act of attack on the World Trade Center is also a most significant threat to computers that could be classified as a physical threat.
Logical Security
Logical security is the practice of employing software-based methods to verify the user’s access rights in a specific computer network. It is a component of the larger field of computer security that encompasses both software and hardware methods to access an account on a network or terminal. In the realm of logical security, it includes password and username token security, as well as two-way authentication of the system.
Password authentication is one of the most well-known and widely used types of security that is logical. Anyone who has utilized an online banking website or social media platform will be familiar with this method. When a social network has been created to make use of password authentication, those who want to sign in to a specific terminal within the web will be required to verify their identity by entering their login name and password.
The advantage of logical security lies in its simplicity. Users need only their username and password information to log into the system. The biggest problem lies in the fact that your computer does not have a method of determining if the person who is using a particular password and username combination is authorized to use it and that shady users could take usernames and passwords and cause harm to the system.
