This aggressive policy seeks to identify and address potential or real security breaches, and the result is a solid high-performance computing environment with a high level of security. In November 1998, NCSA eliminated the use of clear text logins and passwords on its high-performance computer systems to further enhance network security. Since 1998 NCSA and the Alliance have focused security efforts on developing and deploying a security infrastructure for the Alliance computational grid .
Hackers often use the newly discovered passwords to login to a system.
Note that you cannot use SSH or SCP to connect to the NCSA UniTree mass storage system. You may connect to any Alliance computational resource for which you have an allocation using an Alliance digital certificate and PKI-enabled software. Further details about the Alliance PKI are available online . Kerberos You may connect to any NCSA computational resource for which you have an allocation using Kerberos-enabled software. Additional information about Kerberos , including links to sources for Kerberos-enabled binaries is provided online.
