Creating – PVSS Controls

Creating – PVSS Controls

Entity controls

Entity control can be done by Public key infrastructure which sets up entities called certificate authorities. These certificate authorities will be responsible for implementing PKI on the certificates. The certificate authority is trusted such that user is able to delegate the issuance, acceptance, construction, and revocation of certificates to the authority. An analogy to this would be a bouncer who is trusted to only allow some specific people to enter a nightclub.

Network Level Controls

Network access control can be deployed anywhere in the network. In most cases, however, it is deployed close to the Active Directory, in the data center, or in other identity sources that the network uses. The network-level controls will intercept DHCP requests from the network’s connected devices. It does this to profile devices and uses and also carries out authentication of the devices using the identity sources (Pfleeger & Pfleeger, 2002). To enforce these controls on switches, an organization can use SNMP or 802.1x.

Operating System Level controls

The operating system level controls will be defined in the network operating system and will be scheduled to identify the users that are authorized. It will also specify the access privileges that go in line with the other controls. For administrative privileges by the users on accounts, they must receive additional scrutiny by the two-factor authentication tokens. The controls will be able to terminate temporary accounts automatically, disable inactive accounts, and audit the creation of accounts, modification, and termination (Poremba, 2017).

Database Server Level Controls

Database server-level controls can be created through approved authorization to reduce the chances of unauthorized information disclosure and to detect any changes to the information that is not authorized. The control mechanisms will compare the security attributes of data (content and structure), destination objects, and source objects. The appropriate response such as alerting the administrator will take place.
