Product OverView The ISG Series Integrated Security Gateways are ideally suited for securing enterprise, carrier, and data enter environments where advanced applications, such as VoIP and streaming media, demand consistent, scalable performance. The Juniper Networks ISG1000 and ISG2000 Integrated Security Gateways are purpose-built security solutions that leverage a fourth-generation security ASIC, along with high-speed microprocessors to deliver unmatched firewall and VPN performance. Integrating best-in-class firewall, VPN, and optional Intrusion Detection and Prevention, the ISG1000 and ISG2000 enable secure, reliable connectivity along with network-and applicationlevel protection for critical, high-traffic network segments.
Product Description The Juniper Networks® ISG1000 and ISG2000 Integrated Security Gateways are fully integrated firewall/VPN systems that offer 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 Integrated Security Gateways are firewall/VPN-based systems that deliver security features such as intrusion prevention system (IPS), antispam, Web filtering, and Internet Content Adaptation Protocol (ICAP) antivirus redirection support. The advanced system is further expandable with optionally integrated Intrusion Detection and Prevention (IDP) or as a General Packet Radio Service (GPRS) firewall/VPN for mobile network service provider environments. The ISG Series 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 Integrated Security Gateways allow 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-ofthe- art performance and best-in-class functionality as a firewall/VPN or integrated firewall/VPN/IDP solution with optional security modules. The ISG1000 supports up to two security modules, while the ISG2000 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 is higher cost savings. The ISG Series with IDP utilizes the same award-winning software found on Juniper Networks IDP Series Intrusion Detection and Prevention Appliances. 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,
주중에 이중화 테스트로 인한 야간 작업이 있었다. L4의 FWLB로 이중화가 되어 있다. 한쪽라인의 파워를 다 내렸다. 방화벽 또한 내렸다. 서비스 이상 여부 테스트 이후 다시 올리는데 문제가 발생했다. 뒤의 전원 스위치를 Off로 해서 내렸는데 다시 ON 하는데 IOS가 올라 오지를 않는다. Console로 접속했는데 아무 반응도 없다. 뭔가 에러 표시라도 해줘야 뭘 찾기라도 하는데 정말 아무런 반응 없이 커서만 껌뻑 거린다. 전원을 다시 내렸다 올려도 마찬가지다. Front의 Reset Hole도 몇번을 눌러 봤지만 반응이 없다. 이 새벽에 이일을 어찌 한단 말인가... 전화로 해서 대체 장비 좀 수배 해 달라고 연락 후 고민 고민... 방법이 없다. 마지막으로 전기적 쇼크를 의도적으로 주고자 스위치 ON 상태에서 전원 케이블을 뺏다 꽂았다. IOS가 올라온다. 참나... 엔지니어지만 이런 경우는 설명도 힘들고 이해하기도 힘들다. 잠시간이었지만 이런 황당한 사건으로 스트레스를 받은건 사실이다. 아 요즘 들어 왜 이리 장애가 빈번한걸까....
