Dress to impress: Security risk analysis using bowties
Applying the well-established bowtie method to assess security threats.
Cyber-security meets functional safety
The cyber-threat to industrial control systems is very real, as demonstrated by high profile attacks in recent years.
Cyber risk for the rail engineer
Cyber security issues have pervaded almost all aspects of life as daily data breaches and hacked websites testify. In the rail sector, where previously isolated control systems have become connected to the internet, we have seen a new challenge emerge for engineers tasked with ensuring system reliability, availability, maintainability, safety and now security (RAMSS).
Safe and secure? The integration of safety and security
The emerging terrorism threat worldwide, and in particular, the threat from the well-informed insider wanting to do harm and willing to die for the cause, is challenging conventional security practice at high hazard sites and public places.
Integrated safety and security
Historically, the disciplines of safety and security have often been isolated from one another, including separate regulation, practitioners and documentation. Nuclear safety cases, for example, still explicitly exclude events caused by war, terrorism and sabotage, tacitly invoking a plea that such events are unpredictable.
