Features & Benefits:

Secure Routing

Should you use a router and a firewall to secure your network? By building the branch SRX Series with best-in-class routing and firewall capabilities in one product, enterprises don’t have to make that choice. Why forward traffic if it’s not legitimate?

SRX Series for the branch checks the traffic to see if it is legitimate, and only forwards it on when it is. This reduces the load on the network, allocates bandwidth for all other mission-critical applications, and secures the network from hacking.

The main purpose of a secure router is to provide firewall protection and apply policies. The firewall (zone) functionality inspects traffic flows and state to ensure that originating and returning information in a session is expected and permitted for a particular zone. The security policy determines if the session can originate in one zone and traverse to another zone. This architectural choice receives packets from a wide variety of clients and servers and keeps track of every session, of every application, and of every user. It allows the enterprise to make sure that only legitimate traffic is on its network and that traffic is flowing in the expected direction.

To ease the configuration of a firewall, SRX Series for the branch uses two features—“zones” and “policies.” While these can be user-defined, the default shipping configuration contains, at a minimum, a trust and untrust zone. The trust zone is used for configuration and attaching the internal LAN to the branch SRX Series. The untrust zone is used for the WAN or untrusted Internet interface. To simplify installation and make configuration easier, a default policy is in place that allows traffic originating from the trust zone to flow to the untrust zone. This policy blocks all traffic originating from the untrust zone to the trust zone. A traditional router forwards all traffic without regard to a firewall (session awareness) or policy (origination and destination of a session).

By using the Web interface or CLI, enterprises can create a series of security policies that will control the traffic from within and in between zones by defining policies. At the broadest level, all types of traffic can be allowed from any source in security zones to any destination in all other zones without any scheduling restrictions. At the narrowest level, policies can be created that allow only one kind of traffic between a specified host in one zone and another specified host in another zone during a scheduled time period.

High Availability

High Availability

Junos OS Services Redundancy Protocol (JSRP) is a core feature of the SRX Series for the branch. JSRP enables a pair of SRX Series systems to be easily integrated into a high availability network architecture, with redundant physical connections between the systems and the adjacent network switches. With link redundancy, Juniper Networks can address many common causes of system failures, such as a physical port going bad or a cable getting disconnected, to ensure that a connection is available without having to fail over the entire system. This is consistent with a typical active/standby nature of routing resiliency protocols.

When SRX Series Services Gateways for the branch are configured as an active/active HA pair, traffic and configuration will be mirrored automatically to provide active firewall and VPN session maintenance in case of a failure. The branch SRX Series will now synchronize both configuration and runtime information. As a result, during failover, synchronization of the following information is shared: connection/session state and flow information, IPsec security associations, Network Address Translation (NAT) traffic,

address book information, configuration changes, and more. In contrast to the typical router active/standby resiliency protocols such as Virtual Router Redundancy Protocol (VRRP), all dynamic flow and session information is lost and must be reestablished in the event of a failover. Some or all network sessions will have to restart depending on the convergence time of the links or nodes. By maintaining state, not only is the session preserved, but security is intact. In an unstable network, this active/active configuration also mitigates link flapping affecting session performance.

Session-Based Forwarding Without the Performance Hit

In order to optimize the throughput and latency of the combined router and firewall, Junos OS implements session-based forwarding, an innovation that combines the session state information of a traditional firewall and the next-hop forwarding of a classic router into a single operation. With Junos OS, a session that is permitted by the forwarding policy is added to the forwarding table along with a pointer to the next-hop route. Established sessions have a single table lookup to verify that the session has been permitted and to find the next hop. This efficient algorithm improves throughput and lowers latency for session traffic when compared with a classic router that performs multiple table lookups to verify session information and then to find a next-hop route.

Session-based forwarding algorithm shows the session-based forwarding algorithm. When a new session is established, the session-based architecture within Junos OS verifies that the session is allowed by the forwarding policies. If the session is allowed, Junos OS will look up the nexthop route in the routing table. It then inserts the session and the next-hop route into the session and forwarding table and forwards the packet. Subsequent packets for the established session require a single table lookup in the session and forwarding table, and are forwarded to the egress interface.
