Discussion: Cryptographic Functions (150+150 = 300 words)

The Triple Data Encryption Standards, which refer to symmetric encryption but are an improved form of the DES method, which encrypts the 56-key bit typically, are currently employed in the majority of circumstances. This approach operates by encrypting each block three times with the Triple DES cipher algorithm. ATM PINs are encrypted using this technology. Another method is Twofish, which is a license-free encryption method that ciphers 128 bits of data blocks (Conklin et al., 2018). It is seen as a successor to the Blowfish encryption algorithm. It's worth mentioning that this approach is slower than AES and is used to encrypt files and folders.

            Public Key Infrastructure (PKI) is a framework that aids in identifying and distributing public encryption functions. PKI establishes a set of guidelines and practices that are helpful in the setup of the information exchange. Additionally, it aids in guaranteeing that individual system exchanges take place over potentially vulnerable networks (Stapleton & Epstein, 2016). As a result, it is beneficial because it aids in the authentication and verification of identification when interacting. However, there are concerns with using KPI, such as side key misuse and insufficient client data.

            Tangible securities have a physical deterrent effect. Closed-circuit television surveillance CCTV is an example of this. CCTV cameras are installed in all corners of the building, making monitoring much easier to carry out. The person in charge of the control room will use these to alert security to any situation resulting in a security breach (Stapleton & Epstein, 2016). The perimeter wall provides additional physical protection by ensuring that anyone entering the premises is examined at a single entry point and cleared before progressing. As a result, the organization can exclusively welcome those who have good intentions, reducing the risk of insecurity.
