Revolutionizing Network Management: The Role of NUSA in Enhancing IT Efficiency

The Network User Status Agent (NUSA) transforms the response process for network events, moving from labor-intensive manual efforts to automated solutions. In the past, TNS handled complaints by shutting down user ports and contacting administrators, which consumed significant resources—especially evident during the Welchia/Blaster incidents in August 2003. NUSA aims to streamline incident management by notifying administrators of events, automating actions, and empowering them to resolve issues. Future enhancements promise self-scanning, expanded data availability, and essential network insights for better management.

Presentation Transcript

  1. NUSA Overview Mike Rykowski IT-TNS

  2. The old days… • Complaint or event would get TNS’s attention • TNS would track down user port and shut it off • TNS would try to contact user • After host gets fixed, user would try to contact TNS • TNS would then turn port back on when they can

  3. Barely Treading Water • The process was highly labor intensive • TNS personnel spent lots of time per event • Useful information to fix problem was not getting to the users • Just as long as the number of events was small, TNS was getting by…

  4. Then Came Welchia/Blaster • About 900 ports were shutoff in August 2003, all manually • Most of TNS’s resources were used for this one event • We were not treading water any more, something had to change

  5. Here comes NUSA • Network User Status Agent • Main goals of NUSA: • Notify system administrators of events via a contact DB • Apply actions to events automatically • Give system administrators the power to resolve events (turn ports on, etc.)

  6. NUSA Demo

  7. Possible Future Enhancements to NUSA • Self scanning • Expand to more than security related information • Port level information (port speed, duplex, location, etc.) • Network Statistics/Status • Any network information that system admins might find useful

  8. How to access NUSA • Web based utility • Send email to: nsg-net@northwestern.edu • Provide: • Subnet(s) • Mailing list/email address • Netid(s) of contacts
