Features in 13.0.0 with iAppLX version 2.2

F5 SSL Orchestrator

F5 SSL Orchestrator provides an all-in-one appliance solution designed specifically to optimize the SSL infrastructure, provide security devices with visibility of SSL/TLS encrypted traffic, and maximize efficient use of that existing security investment. This solution supports policy-based management and steering of traffic flows to existing security devices, designed to easily integrate into existing architectures, and centralizes the SSL decrypt/encrypt function by delivering the latest SSL encryption technologies across the entire security infrastructure.

Multi-Layered Security

In order to solve specific security challenges, security administrators are accustomed to manually chaining together multiple point products, creating a bare-bones “security stack” consisting of multiple services. A typical stack may include components like Data Leak Prevention (DLP) scanners, Web Application Firewalls (WAF), Intrusion Prevention and Detection Systems (IPS and IDS), Malware Analysis tools, and more. In this model, all user sessions are provided the same level of security, as this “daisy chain” of services is hard-wired.

Dynamic Service Chaining

Dynamic Service Chaining processes specific connections based on context provided by the Classification Engine. These service chains can include four types of services (Layer 2 in-line services, Layer 3 in-line services, receive-only services, and ICAP services) you define, as well as any decrypt zone between separate ingress and egress devices).

Classification Engine

Classification Engine provides a rich set of methods based on context to dynamically determine how best to optimize the flow through the security stack. Context can come from the following:

  • Source IP/subnet
  • Destination IP/subnet
  • IP intelligence category - Subscription
  • IP geolocation
  • Host and domain name
  • URL filtering category - Subscription
  • Destination port
  • Protocol

Deployment modes

SSL Orchestrator provides mulitple deployment modes to address a variety of user needs. It can be deployed in any of the following modes:
  • Single device mode
  • Separate ingress and egress devices mode
  • Single high availability (HA) cluster mode
  • Separate ingress cluster and egress cluster mode

Behavior changes in 13.0.0 with iAppLX version 2.2

ID Number Description
634030 Previously, the Layer 3 inline server received traffic with a SNAT client IP address. Now, the Layer 3 inline server sees the original client IP address unless it cannot handle the IP protocol (for example, the traffic is IPv6, but the inline server can only handle IPv4 traffic).

Prior to 2.2, SSL Orchestrator would use a SNAT pool of addresses when sending traffic through a Layer 3 inline device. This simplified routing, but hid the source address from those devices. Beginning in version 2.2, SSL Orchestrator will only SNAT traffic if there is an IP protocol version mismatch between the client traffic and the inline service devices. All other traffic will be forwarded without changing the address, allowing inline services to see the actual source address and use that in their decisions.

The impact of this change: Any layer 3 inline service devices will need to be configured with a static route for all internal networks pointing to a next hop of the inward BIG-IP address. This address can be determined by looking at the addresses in the server selection box and should use the “.1” IP address of the subnet range that includes the selected server (for example, if the selected server is (/25 is assumed), the next hop configured on the device should be
Table 1. IPv4 Traffic Example
Layer 3 Service Selectable Server Addresses Mask Static Route next hop for internal networks Default Route next hop for external addresses
Service #1
Service #2
Service #3
If the Layer 3 address range has been changed, it would be a similar address within the new range.

Before upgrading to version 2.2, any Layer 3 inline devices should be checked and updated as needed to make sure they will correctly route traffic back to the SSL Orchestrator.
