AT&T long-distance network crash (January 15, 1990), in which the failure of one switching system would cause a message to be sent to nearby switching units to tell them that there was a problem. Unfortunately, the arrival of that message would cause those other systems to fail too – resulting in a cascading failure that rapidly spread across ...
Ntpd-rs with Network Time Security for NTP (NTS) support. After the first major incidents, it became clear that apart from stating a server's access policy, a technical means of enforcing a policy was needed. One such mechanism was provided by extending semantics of a Reference Identifier field in an NTP packet when a Stratum field is 0.
Random numbers typically go through several layers of hardware and software before they are used. Bits may be generated in a peripheral device, sent over a serial cable, collected in an operating system utility and retrieved by a system call. The subverted bits can be substituted at any point in this process with little likelihood of detection.
Reusing software modules does not guarantee safety in the new system to which they are transferred ..." [6] In response to incidents like those associated with Therac-25, the IEC 62304 standard was created, which introduces development life cycle standards for medical device software and specific guidance on using software of unknown pedigree.

An incident response plan (IRP) is a group of policies that dictate an organizations reaction to a cyber attack. Once an security breach has been identified, for example by network intrusion detection system (NIDS) or host-based intrusion detection system (HIDS) (if configured to do so), the plan is initiated.

Additionally, a failure of the university's Central Authentication Service caused course registration and other services to become unavailable during critical times in the academic semester. The university reportedly spent $300,000 in consultation and increased the cyber-security budget of the university by $1 million in response to these attacks.
Primarily due to low rates of anti-virus detection against this type of rapidly changing malware. Parsing, log normalization and categorization can occur automatically, regardless of the type of computer or network device, as long as it can send a log. Visualization with a SIEM using security events and log failures can aid in pattern detection.
