For Connection Server instances, security servers, and View desktops, you can enable RC4 on a
Connection Server, security server, or a Horizon Agent machine by editing the configuration file
C:\Program Files\VMware\VMware View\Server\jre\lib\security\java.security. At the end of
the file is a multi-line entry called jdk.tls.legacyAlgorithms. Remove RC4_128 and the comma that
follows it from this entry and restart the Connection Server, security server, or the Horizon Agent machine,
as the case may be.
For View Composer and View Agent Direct-Connection (VADC) machines, you can enable RC4 by
adding the following to the list of ciphers when you follow the procedure "Disable Weak Ciphers in
SSL/TLS for View Composer and Horizon Agent Machines" in the View Installation document.
TLS_RSA_WITH_RC4_128_SHA
TLS 1.0
In Horizon 7, TLS 1.0 is disabled by default.
For more information, see https://www.pcisecuritystandards.org/documents/PCI_DSS_v3-1.pdf and
http://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-52r1.pdf. For instructions on how to
enable TLS 1.0, see the sections "Enable TLSv1 on vCenter Connections from Connection Server" and
"Enable TLSv1 on vCenter and ESXi Connections from View Composer" in the View Upgrades document.
