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.
Answer:
Add the hex value to the appropriate base-
16 place-value column: 2 in the 16 column; D in the 1 column.
Work out the hex digits and their representation in denary-
2 = 2 in denary; D = 13 in denary.
Multiply with the place value: 2 x 16 = 32; 13 x 1 = 13.
Add the values together: 32 + 13 = 45 in denary.
