We want to use SNMP to remotely monitor and manage our installation – why do you not support such standard SNMP traps as CPU and Memory exhaustion?

Those sorts of traps were specifically excluded because they can be used to establish a covert channel (an illicit signaling channel that can be used to communicate from a high assurance “area” to a lower assurance one in an effort to circumvent the security policy). Resource exhaustion events/alerts are the oldest known form of covert channel signaling. Exercise care with any HSM product that does allow such traps - what other basic security holes might be present?
