What Is Layered Security Maintenance

Based on layers of solutions, security maintenance is implemented at the following layers: application layer, system layer, network layer, and management layer. Figure 1-1 shows the security maintenance layers.

Figure 1-1 Security maintenance layers

Application Layer

Security maintenance at this layer is conducted to ensure that applications of the solution run properly and provide services normally.

The application layer of the CloudEC on-premises conference-only solution mainly consists of services provided by the service management center 2.0 (SMC2.0), Switch Center (SC), enterprise unified address book (USM-EUA), CloudMCU, VP9600 series multipoint control unit (MCU), RSE6500, telepresence and videoconferencing endpoints, TE Desktop, and TE Mobile. The security maintenance of this layer meets the application security requirements of various services provided by these servers.

System Layer

Security maintenance at this layer is conducted to ensure that the operating system and database run properly, ensuring the proper running of applications at the application layer.

Security maintenance at the system layer is implemented based on maintenance terminals or tools of maintenance objects.

Network Layer

Security maintenance at this layer is conducted to ensure the proper running of switches, routers, firewalls, and the VPN gateway so that the application of security policies (such as the firewall access-control policy and the VPN encryption policy) is ensured.

Security maintenance at the network layer is implemented based on maintenance terminals or tools of maintenance objects.

Management Layer

Security maintenance at this layer is conducted to enhance manual management and log and patch management to prevent potential risks. The preceding layers are involved in management-layer security maintenance.
