Intrusion detection/prevention system (IDS/IPS)
- Deep packet inspection — module supports deep packet inspection and examines the packet payload as well as the frame and packet headers; packets are dropped if attacks or intrusions are detected using signature-based or protocol anomaly-based detection
- Severity-based action policies — involve action taken against attacks based on their severity; available actions are "allow," "block," and "terminate connection" to provide appropriate mitigation
- Signature update service — provides regular updates to the signature database, helping to ensure that the latest available signatures are installed
- Signature-based detection — detects known attacks that have known attack patterns; the IPS maintains a signature database that contains the pattern definitions for known attacks, and can be automatically updated using a subscription service
- Protocol anomaly-based detection — detects anomalies in application protocol header using signatures
Data center protection
- Server protection — stateful firewall controls traffic to the data center; intrusion protection system (IPS) detects and blocks threats such as worms and viruses to maintain service and application availability
Compartmentalization
- Departmental protection — allows organizations to define departmental security policies to protect local resources with a stateful firewall and IPS while at the same time allowing high-performance access to common resources
VPN concentration
- Site-to-site connectivity — IPSec-encrypted tunnels help ensure privacy between sites with optional Generic Routing Encapsulation (GRE) tunneling, which is available for full deployment flexibility; intersite links can be deployed quickly and controlled with tunnel policies
- Secure remote access — can be delivered for remote users via securely authenticated IPSec tunnels
Firewall
- Stateful firewall — enforces firewall policies to control traffic and filter access to network services; maintains session information for every connection passing through it, enabling the firewall to control packets based on existing sessions
- Zone-based access policies — logically groups virtual LANs (VLANs) into zones that share common security policies; allows both unicast and multicast policy settings by zones instead of by individual VLANs
- Application-level gateway (ALG) — deep packet inspection in the firewall discovers the IP address and service port information embedded in the application data; the firewall then dynamically opens appropriate connections for specific applications
- NAT/PAT — choice of dynamic or static network address translator (NAT) preserves a network's IP address pool or conceals the private address of network resources, such as Web servers, which are made accessible to users of a guest or public wireless LAN
- DoS attack prevention — firewall is able to detect various denial-of-service attacks and take appropriate action to mitigate the threat
- Authenticated network access — firewall can authenticate the user at a given IP address using RADIUS or a local user directory before allowing connections from that location
Virtual private network (VPN)
- IPSec — provides secure tunneling over an untrusted network such as the Internet or a wireless network; offers data confidentiality, authenticity, and integrity between two endpoints of the network
- Layer 2 Tunneling Protocol (L2TP) — is an industry standard-based traffic encapsulation mechanism supported by many common operating systems; will tunnel the PPP traffic over IP and non-IP networks; and may also use the IP/UDP transport mechanism in IP networks
- Manual or automatic key exchange (IKE) — provides both manual or automatic key exchange required for the algorithms used in encryption or authentication; auto-IKE allows automated management of the public key exchange, providing the highest levels of encryption
- Network Address Translation-Traversal (NAT-T) — enables IPSec-protected IP datagrams to pass through a network address translator (NAT)
- Digital certificate management — digital certificates can be utilized to authenticate to an IPSec VPN gateway; this also supports certificate revocation list (CRL) and allows certificates to be imported through a Simple Certificate Enrollment Protocol (SCEP) server
- Site-to-site connectivity — two IPSec VPN gateways can be configured to provide secure site-to-site communication between offices, partners, or suppliers; both IPSec or GRE tunnels are available
- Generic Routing Encapsulation (GRE) — can be used to transport Layer 2 connectivity over a Layer 3 path in a secured way over IPsec; enables the segregation of traffic from site to site; provides dynamic routing and static failover
- Secure remote access — allows remote users to connect to the VPN gateway for secure communication to the corporate network over the public network; provides the flexibility to use the following VPN clients: Openswan VPN client for Linux, Shrew Soft VPN client, IPSecuritas VPN client for Macintosh OS X, Microsoft® Windows® XP native VPN client, Microsoft Windows Vista® native VPN client, and Microsoft Windows 7 native VPN client (both 32 bit and 64 bit)
Operating modes
- Route Mode — provides the deployment of the firewall, VPN, and IPS in line with traffic for deep packet inspection to control and filter traffic; supports static routes, RIP, RIPv2, OSPF, IGMP, and PIM
- Monitor Mode — provides the deployment of the intrusion detection system (IDS) to monitor traffic passively out of band with the traffic
Management
- Remote configuration and management — is available through a secure Web browser or a command-line interface (CLI)
- Secure Web GUI — provides a secure, easy-to-use graphical interface for configuring the module via HTTPS
- Command-line interface (CLI) — provides a secure, easy-to-use command-line interface for configuring the module via SSH or a switch console; provides direct real-time session visibility
- HP PCM Plus and HP Network Immunity Manager — provides central management of multiple TMS zl Modules for discovery, status management, and configuration
- Logging — provides local and remote logging of events via SNMP (v2c and v3) and syslog; provides log throttling and log filtering to reduce the number of log events generated; support for email logging
Connectivity
- Two 10-GbE connections to the switch — two 10-GbE wire-speed internal connections help ensure that the network connections from application to switch backplane will not limit the performance of the application
Performance
- High-performance network bandwidth — includes two internal wire-speed 10-GbE ports to the switch backplane
- High-performance processor system — Intel® Core™ 2 Duo Processor T7500 with 2.2 GHz, 4 MB cache provides a high-performance compute environment in a small footprint using a single switch slot
- Memory subsystems — 4 GB of DDR2-667 dual-channel memory provides for quick application performance
- Disk drive — 250 GB SATA II 7200 rpm hard disk drive (210 GB application space plus 40 GB diagnostic/maintenance space) allows quick data reads/writes to speed applications along
Resiliency and high availability
- Redundant power supplies — services module has the same level of power supply redundancy as the switch in which it is installed
- High availability — two modules can work together to provide high availability and redundancy; modules in the high-availability cluster share connection state information to provide stateful failover; active-standby failover is supported
Ease of use
- Locator LED (module) — allows users to set the locator LED on a specific module to either turn on, blink, or turn off; simplifies troubleshooting by making it easy to locate a specific module among other identical or similar modules
