Software Survivability: Where Safety and Security Converge
Karen Mercedes Goertzel, Larry T. Feldman · AIAA Infotech@Aerospace Conference · 2009
As safety-critical software moves from closed environments to open and commodity technologies, security threats will inevitably increase. Organizations dependent on mission-critical systems and networks are recognizing that the traditional “protect-detect-react” (PDR) strategy for countering intrusions and attacks is ineffective. A new information assurance and cybersecurity strategy is needed that augments PDR with the ability of systems and networks to “fight through” attacks. This article examines techniques that both security- and safety-critical software developers can leverage to increase their software’s survivability.
