Cyber security can be defined as a preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
Generally, redundancy to prevent unauthorized access can be implemented at a number of points throughout the security architecture, such as in firewalls, proxy servers and access controls.
A firewall is a network security protocol that monitors and controls inbound and outbound traffic based on set aside security rules.
Generally, a firewall is used to control access to a computer or network, as it creates a barrier between a computer or a network and the internet in order to protect against unauthorized access. It is a security system pre-installed on most computers to essentially inspect data being transmitted to or from a computer.
An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.
Simply stated, access control is the process of verifying the identity of an individual or electronic device.
