A method and system for quickly informing a backup unit that a primary unit has failed. Normally an exception handler is activated when a software failure occurs and network controller chips or the ASIC interface to a signal bus can operate even though there is a software failure. A software failure notification packet is programmed and stored in a location that is not affected by a software system failure. When a software failure occurs, control is shifted to the exception handler. The exception handler sends a pre-established and pre-addressed packet to the network controller card which transmits this packet to the backup unit. Upon receipt of the packet, the backup unit goes into operation. In some alternate embodiments that include multiple line cards in a single unit, the exception handler sends a signal to a backup unit via a signal bus or a data bus.

Introduced here are computer programs and computer-implemented techniques for discovering malicious emails and then remediating the threat posed by those malicious emails in an automated manner. A threat detection platform may monitor a mailbox to which employees of an enterprise are able to forward emails deemed to be suspicious for analysis. This mailbox may be referred to as an “abuse mailbox” or “phishing mailbox.” The threat detection platform can examine emails contained in the abuse mailbox and then determine whether any of those emails represent threats to the security of the enterprise. For example, the threat detection platform may classify each email contained in the abuse mailbox as being malicious or non-malicious. Thereafter, the threat detection platform may determine what remediation actions, if any, are appropriate for addressing the threat posed by those emails determined to be malicious.
