Instead of transferring messages in clear text, the messages in this secure system are encrypted with a secret key. The secret key is exchanged using a public/private key protocol. Users present their certificates through the grid engine system to prove identity. Users receive the certificate to ensure that they are communicating with the correct systems. After this initial announcement phase, communication continues transparently in encrypted form. The session is valid only for a certain period, after which the session must be re-announced.
Increased Security Features are not available if you intend to use Windows hosts as execution hosts.
