JSA Appliance Models

Juniper Secure Analytics (JSA) appliances are designed to respond to the right threats at the right time through effective analysis of networks, events, and audit log files. JSA has the ability to identify environmental anomalies in the network, an attack path, and the source of a threat. JSA provides network remediation for threat responses across all security products.

The JSA appliances use two drivers, Security Information Management (SIM) and Security Event Management (SEM), for security analysis of external and internal threats. SIM provides reporting and analysis of data from host systems, applications, and security devices to support security policy compliance management, internal threat management, and regulatory compliance initiatives. SEM improves security incident response capabilities by processing data from security devices and network devices. It helps network administrators to provide effective responses to external and internal threats.

Table 1 lists the Juniper Secure Analytics (JSA) appliance models.
