A hands-on guide to implementing Cisco ASA
Configure and maintain a Cisco ASA platform to meet the requirements of your security policy. Cisco ASA Configuration shows you how to control traffic in the corporate network and protect it from internal and external threats. This comprehensive resource covers the latest features available in Cisco ASA version 8.0, and includes detailed examples of complex configurations and troubleshooting. Implement and manage Cisco's powerful, multifunction network adaptive security appliance with help from this definitive guide.
- Configure Cisco ASA using the command-line interface (CLI) and Adaptive Security Device Manager (ASDM)
- Control traffic through the appliance with access control lists (ACLs) and object groups
- Filter Java, ActiveX, and web content
- Authenticate and authorize connections using Cut-through Proxy (CTP)
- Use Modular Policy Framework (MPF) to configure security appliance features
- Perform protocol and application inspection
- Enable IPSec site-to-site and remote access connections
- Configure WebVPN components for SSL VPN access
- Implement advanced features, including the transparent firewall, security contexts, and failover
- Detect and prevent network attacks
- Prepare and manage the AIP-SSM and CSC-SSM cards
