pages that could use one of two secure protocols to encrypt communications (What is HTTPS, n.d.). The first is SSL (Secure Sockets Layer) and the second is TLS (Transport Layer Security) and both use what is known as an asymmetric Public Key Infrastructure (PKI) system (What is HTTPS, n.d.). With an asymmetric system it uses two keys to encrypt communications, a public key and a private key (What is HTTPS, n.d.). Therefore, anything encrypted with the public key can only be decrypted by the…

User connectivity will be controlled and authenticated through active directory. User devices will require and object to be created in active directory which will be used to authenticate the device using 802.1x. When a user device is connected to the network it will initially communicate on a VLAN will only be allowed to communicate with active directory. Then once the device has been authenticated it will place the device on the appropriate VLAN that it will operate on. Any device that has not…
