The campus network certification system is not the end point; the real test is daily wiring. Many schools focus on light-vigils, and the system runs unattended until a large number of students and teachers complain about it. It's connected to everyone's online experience, and its operation needs constant attention. Here, we can get out of the few most sensitive lines of day to day, and help deliver the little bits of it.
Resource water level for authentication servers
The first thing to look at is the health of the certified server. The basic indicators are processors, memory, connections, and there must be continuous monitoring and threshold alerts."The network's down."But it's probably because the server can't hold it. We suggest that a separate monitoring panel be set up for the certified server, and resources start warning seven accomplishments before they wait 100%. Water levels are boring, and critical times save lives.
The lifeline of the certification success rate.
More directly than server resources, the certification success rate. How many times a day is a successful login, how many times a failure and whether there are any abnormally high failure rates, this curve best reflects the true state of the system. If one day’s failure rate rises from one in 1,000 to five percent, it tends to be more problematic than any warning: it may be synchronized, it may be that some kind of device has been compatible or it may have been tactically wrong.
The account synchronisation state cannot be blinded
The system with the unified identity is followed by a simultaneous account. The synchronization of tasks is another point to be looked at. It must be visible if it runs on time, how many have succeeded, how many have failed and whether it has been stuck. If the synchronisation fails, new teachers and students will not be able to access the Internet, and the synchronous service itself will not be wrongly reported. We suggest that the synchronizing task is carried out back to send a warning, and we keep the last sync to identify which data is the problem.
Unusual login and alert.
The security dimensions of the system are to be looked at in an abnormal mode. The same account entry from multiple locations, an account number and a large number of simultaneous devices, and the presence of a large number of unknown terminal certifications at night may mean that the account numbers are stolen or webed. If the system is best monitored with unusual means that no one carries a normal dimension of the authentication log. We stress this because the certification system is the first door on the campus network, which is then mass-dumped and the security design behind it is empty.
The combined effects of the change in strategy
The transporter can't change his strategy without adjusting to the connection. If you change your dormitory speed, the teacher will be injured by a mistake. If you add an access period, the night work of science will be interrupted. We suggest that the strategy should change."You'll see it easy and then you'll tighten it."The pace, and the changes in the indicators for a few days, confirm that there is no abnormal fixation. The strategy is alive, but it has to be looked at every time it moves, otherwise the minor changes have gone into a major malfunction.
I'm gonna have to keep my broken muscle memory.
Finally, good surveillance has to be handled. The crew regularly rehearses common failures: how the authentication server is cut, how the sync is broken, how the large area is quickly located. Writing these steps into manuals and occasionally going through them will not be blind at a critical time. The system is unstable, half looking at structures, and half looking at the feeder's muscle memory.
The carrier's account is on hand.
Every malfunction, every strategy adjustment, daily disposal. It is recommended to write down a copy of the manifest: when, which building, what event, how to solve it. The bill is a slurping straw for the transfer.——When you change or rewrite, you can only rely on memories, which are the most unreliable. We treat them as external memories of the system that allow for the accumulation and transmission of experience in carrying, rather than walking away with people.
I can't let the holidays go.
The summer holidays are characterized by a small number of people online, but precisely the centralization period for system upgrades, major equipment changes and strategy re-engineering, which is not easy. We suggest that holiday lines be strengthened to ensure that normal day changes are made in low peak windows while keeping track of success rates. Many school holidays are out of focus until they start, and when one of the changes is mined, it starts to explode.
We need to treat the noise.
There's a lot of surveillance stores that can easily turn themselves on: everything is called to the alarm, and it's important to be flooded. We've seen a few hundred delivery guards trained for useless warnings."The wolf's here."The condition is reflected, and the failure is not taken seriously. So alerting the alarms to be fixed, adjusting the threshold to make real impact certification sound, just low-priority aggregates in daily reports."It's always quiet. Something happens."And not every second. Noise is fixed, surveillance is the asset, or just another noise source.
