Logjam is a new security vulnerability that has been in the news recently. Logjam affects customers using SSL / TLS with weak cryptographic ciphers available on web servers. If these weak ciphers are not disabled, a man-in-the-middle attack can be used to downgrade a strong cipher suggested by the browser to a vulnerable cipher.
ZMF REST Services Getting Started Guide, all secure communication functionality (i.e. SSL) associated with this processing on z/OS must be implemented using IBM's Application Transparent Transport Layer Security (AT- TLS ). Some customers may have found and implemented other solutions that address their specific needs (e.g. the implementation of native Apache Tomcat SSL connectors). However, if problems are encountered
The underlying connection was closed: Could not establish trust relationship for the SSL/ TLS secure channel. Additionally, in .\Documents and Settings\<User_ID>\Application Data\Serena\Meritage\meritage.log the following will be found: 2005-07-12 11:54:18,777 [3908] INFO Merant.DocShare.UI.Forms.ServerSetupForm - The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.
Logon operations can hang and provide no response when zMobile is configured to run with SSL connections. This primarily affects customers who have customised their environment to use native Tomcat security (i.e. redefined the connector to use SSL). However, AT- TLS customers could also see the same behaviour if they have not configured their policy rules in the correct manner.

When running web servers administrators choose which level of security they want to use. One of the more robust configurations is using TLS and Perfect Forward Secrecy. This involves clients and servers agreeing on a protocol, cipher, and eventually a unique key for a session.
Serena Mariner on Demand and Agile on Demand require SSL 3.0 or TSL 1.0 in order to access the website. By default Internet Explorer 6 and 7 have these encryption algorithms enabled. If SSL 3.0 and TLS 1.0 are disabled you will see a message that says "Internet Explorer cannot display the webpage" instead of the login page.
