    encryption keys for the authentication mechanism. Secret key are stored in a key distribution center and act as a trusted third party. Kerberos services can be divided into two session, TGT services and TGS service. In TGT services, Authentication between client and host using the active directory takes place and TGS services, which generate session tickets for a valid TGT. By using Kerberos, client can prove its identity to server across an insecure connection because it using strong encryption keys. •

A variety of PUFs have used manufacturing variability6,7or materials disorders8–13for generating a security keyon demand. Specifically, applying a challenge (such as anelectrical or an optical stimulus) to a PUF produces a unique response (a security key).Hence, this concept generates security keys that are unique for each electronic device.

    Recommendations for Prevention/Mitigation Many ports do not have cyber response plans contained within broader risk plans (Kramek). All of the ports studied by Kramek had a dedicated security officer and a dedicated IT staff, but the security officers’ focus usually remained on traditional physical security threats, and IT was a separate and distinct department from security (Kramek). Kramek states, "cyber security threats were not part of the security officer’s response portfolio". Most security
