Juniper NS-ISG-1000 Hardware Firewall Networking

The Juniper Networks ISG 1000 and ISG 2000 are fully integrated firewall/VPN systems
that offers multi-gigabit performance, modular architecture and rich virtualization
capabilities. They are an ideal security solution for large enterprise, data center and
service provider networks.
The ISG Series firewall/VPN-based systems deliver security features such as Intrusion
Prevention System (IPS), anti-spam, Web filtering, and Internet Content Adaptation
Protocol (ICAP) antivirus redirection support. The advanced system is further
expandable with optionally integrated IDP or as a General Packet Radio Service (GPRS)
firewall/VPN for mobile network service provider environments.
The ISG Series firewall/VPN modular architecture enables deployment with a wide
variety of copper and fiber interface options. Highly flexible segmentation and isolation
of traffic belonging to different trust levels can be achieved using advanced features
such as virtual systems, virtual LANs, and security zones. The ISG Series firewall/VPN
allows multiple, separate firewall inspection or routing policies to simplify network
design. This enables the enforcement of security policies to traffic streams—even in
highly complex environments—without significant impact on the network itself.
The flexibility and efficiency offered by the ISG Series architecture provides state-of-
the-art performance and best-in-class functionality as a firewall/VPN or integrated
firewall/VPN/IDP solution with optional security modules. The ISG 1000 supports up to
two security modules, while the ISG 2000 can support up to three security modules.
The security modules maintain their own dedicated processing and memory, and
incorporate technology designed to accelerate IDP packet processing. This reduces
the number of separate security devices and management applications, and simplifies
deployment effort and network complexity. The result? Higher cost savings.
The ISG Series firewall/VPN with IDP utilizes the same award-winning software found
on Juniper Networks IDP platforms. The IDP security module supports multi-method
detection, combining eight different detection mechanisms—including stateful
signatures and protocol anomaly detection. In addition to helping businesses defend
against security threats such as worms, trojans, malware, spyware, and hackers, the
ISG with IDP can provide information on rogue servers as well as types and versions
of the applications and operating systems that may have inadvertently been added
to the network. Application signatures go a step further by enabling administrators to
maintain compliance and enforce corporate business policies with accurate detection of
application traffic.
The ISG 1000 and ISG 2000 can be deployed in a number of different configurations to
protect both the perimeter and internal network resources. When deployed in a mobile
operator network, the ISG 1000 and ISG 2000 GPRS solutions are GPRS Tunneling
Protocol (GTP) aware and fully support GTP functionality in virtual systems. The ISG Series
firewall/VPN can be deployed at the Gp interface connection between two Public Land
Mobile Networks (PLMN), the Gn interface connection between the SGSN and the GGSN
support nodes, and the Gi interface connection between the GGSN and the Internet.
In addition to countering sophisticated threats, denial of service (DoS) attacks, and
malicious users, the ISG Series GPRS firewall/VPN can limit messages, throttle bandwidth-
hungry applications that consume uplink/downlink traffic, and perform 3GPP R6 IE
removal to help retain interoperability in roaming between 2G and 3G networks.
