La gestione delle patch è un problema che deve sempre essere affrontato attentamente, specialmente se siamo in ambienti industriali (sistemi di controllo), soprattutto nelle Infrastrutture Critiche
--Software Update
Caused Emergency Shutdown at Nuke Plant (June 5, 2008)
Flaws in a software
update caused the Hatch nuclear power plant in Baxley, GA to shut down in early
March of this year. The software update
was made on just one computer on the plant's business network.
That computer monitors chemical and diagnostic data from
one of the plant's primary control systems.
A spokesperson said the emergency system reacted as it was designed to
and that the security and safety of the plant were never in danger.
Although technicians knew of the two-way
communication between some computers on the corporate and control networks, the
engineer who installed the update was not aware that reboot on the corporate
side would force a reset on the control side.
Network connections between the
affected servers have since been severed.
