Additional Notes Note on Encryption Fix in 11.6 Connection encryption, which in some circumstances was found to be intermittent, has been fixed. Below is additional information about the defect, the circumstances in which the defect may affect performance, and mitigation options. Defect Description By default, connections between Proxy components (for example, Master-toHost, Gateway-to-Host, Master-to-Gateway) use encryption (the current version is set by default to use the AES 256-bit cypher).
o Only peer-to-peer or Gateway-managed connections within the same domain are vulnerable to this defect, but most corporate domains are protected and considered safe environments. o Proxy data, while not encrypted, is encoded in a proprietary format and compressed, so intercepting and decoding that data would not be a casual challenge. Also note that this defect does not affect the initial connection between Proxy components.
Table 1. Mitigation Options for Encryption Defect Mitigation Options No Action Upgrade Proxy clients & servers to 11.6 Upgrade Proxy clients only (Masters, Gateways) Upgrade Proxy servers (Hosts) only Patch Proxy clients & servers to 11.
