Publisher Summary PIX device manager (PDM) is a highly capable graphical interface for managing the PIX firewall. In addition to providing nearly all CLI functionality, PDM includes several features to further simplify the ongoing maintenance and operations that firewall administrators and security policy makers perform. Because PDM is Java based and runs as a signed applet over an SSL-encrypted browser session, administrators can use it securely from any authorized client. This remote management capability can be highly valuable in large and distributed environments. The most powerful functionalities of PDM are the PDM wizards, which include the Startup Wizard and the VPN Wizard. Using these tools, administrators are guided through the complex processes of building PIX configurations and VPN tunnel services. In addition to the wizard functionality, PDM facilitates full configuration of PIX firewall access, AAA, filter, NAT rules, logging, user accounts, and IDS configurations. This functionality includes the ability to manage complex, grouped service, and network objects, which is a new functionality in the PIX firewall software. The PDM GUI (Graphical user interface) is intuitive, well organized, and helps prevent accidental syntax and configuration errors, which can cause the firewall to fail. Moreover, PDM can be used as a CLI learning tool for administrators who are not completely proficient with the PIX firewall command line by previewing all commands sent to the PIX.
