Host Licensing

Full Integrated Security & Networking Feature Suite (PIX OS 6.x Only; Max 6.3(5))

1. Stateful Inspection Firewall (Cisco Adaptive Security Algorithm)

• Full stateful packet inspection that tracks all TCP/UDP connection state, eliminating vulnerabilities of stateless packet filters
• Static, dynamic and turbo access control lists (ACLs) for granular inbound/outbound traffic permission/denial rules
• Multi-vector DoS/DDoS flood mitigation, malformed packet blocking and port scan detection
• Layer 7 application inspection engines for FTP, H.323, SIP, Skinny SCCP, RTSP, NetBIOS and multimedia protocols to maintain NAT traversal for VoIP and video workloads
• Native Java/ActiveX content filtering and third-party web URL filtering integration

2. Standards-Based IPsec VPN Suite

• Site-to-site LAN-to-LAN IPsec tunnels for secure inter-branch connectivity over public internet
• Remote access IPsec VPN for teleworker Cisco VPN Client software tunnels back to corporate headquarters
• IKEv1 key exchange protocol, compatible with DES, 3DES, AES encryption and MD5/SHA-1 authentication
• X.509 digital certificate enrollment via SCEP for scalable multi-site VPN deployments
• GRE tunnel encapsulation for routed non-IPsec traffic across VPN links

3. Broadband NAT & Routing Services

• Static one-to-one NAT, dynamic NAT pools, PAT port address translation to share a single public IP across dozens of internal endpoints
• Native PPPoE client for DSL broadband ISP authentication and dynamic public IP assignment
• Local DHCP server supporting up to 256 internal IP address leases for LAN endpoints
• Static routing and policy-based routing (PBR); IPv4-only native support (no native IPv6 protocol stack on PIX OS 6.x)
• Local DNS caching to reduce external DNS query latency

4. Inline Intrusion Detection & Threat Defense

• Built-in IDS engine with 55+ predefined attack signatures to detect worms, exploits and brute-force network scanning
• Automatic dynamic host blocking to quarantine malicious source IP addresses after detected security events
• Unicast Reverse Path Forwarding (URPF) anti-spoof filtering to block forged source IP traffic

5. AAA Access Control & Audit Logging

• Complete AAA authentication, authorization and accounting via external RADIUS and TACACS+ servers
• Local user credential database for standalone device administrative login
• Persistent local event logging + remote Syslog export to external SIEM/log servers for compliance audit trails
• SNMP v1/v2 monitoring for device health, traffic utilization and fault alert reporting

Management & Configuration Tools

1. PIX CLI Console: Traditional Cisco IOS-style command-line interface via serial console or SSH remote access
2. PIX Device Manager (PDM v3.0.4): Embedded HTTPS web-based graphical GUI for single-device visual configuration, real-time traffic charts and security event reporting
3. Cisco Secure Policy Manager (CSPM): Centralized enterprise policy management platform for bulk multi-PIX deployment orchestration
4. TFTP image backup/restore for firmware OS and full configuration file archiving

Key Differentiators vs PIX-501 & Original PIX-506

1. vs PIX-501: No internal 4-port LAN switch, unlimited internal host license (no 10/50 user cap), higher 25,000 concurrent sessions and 25 VPN tunnel capacity
2. vs Original PIX-506: Faster 300 MHz CPU, 10/100 auto-sensing Fast Ethernet ports (fixed 10 Mbps only on base PIX-506), 100 Mbps cleartext throughput (20 Mbps on PIX-506), higher AES/3DES VPN encryption throughput, optimized power dissipation

Typical Historical Deployment Scenarios

1. Multi-user small branch office internet edge firewall for businesses with 10+ internal staff and external LAN switches
2. Regional retail satellite store secure IPsec VPN gateway connecting remote locations back to corporate headquarters
3. Mid-sized teleworker hub for distributed field teams with unlimited internal wired endpoints
4. Small remote branch backup VPN security appliance for redundant enterprise WAN connectivity
5. Legacy network lab training platform for PIX OS stateful firewall and IPsec VPN learning environments

Naming Rule Explanation

• PIX: Cisco legacy dedicated firewall product family acronym (Private Internet Exchange), fully replaced by the ASA Adaptive Security Appliance line
• 506: Mid-tier small-branch model number within the PIX 500 SOHO sub-series
• E: Enhanced hardware refresh suffix indicating upgraded 300 MHz CPU, 10/100 auto-negotiation and improved performance vs the base PIX-506
• Hardware Limitation Note: The PIX-506E only supports PIX OS 6.x firmware and cannot run PIX OS 7.x or later releases; it lacks rack-mount hardware and does not include the built-in 4-port LAN switch featured on the entry PIX-501 platform.
