NCSA's aggressive policy seeks to identify and address potential or real security breaches. The result is a solid high-performance computing environment with a high level of security. Defensive measures are quickly employed in those rare cases of intrusion with the goal of not compromising user data and the HPC systems. In November 1998, NCSA eliminated the use of clear text logins and passwords on its high-performance computer systems to further enhance network security. The team discussed their general security plans with representatives from the Defense Department and NSF-funded laboratories and agreed that the various organizations would use interoperable authentication schemes and security architectures.
Hackers often use the newly discovered passwords to login to a system.
