1. Department of Information Technology NUSA Overview Mike Rykowski IT-TNS

2. Department of Information Technology 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. Department of Information Technology 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. Department of Information Technology 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
