The issue focused on technology -- devices that help computers understand what software is doing to computer systems. Microsoft engineers use digital cameras and sensors to assess Windows machines. IBM hackers get electronic fingerprint scanners. There are algorithms for computing robots, driving cars, airplanes and TVs.

To Windows programmers, some technologies such as hacking machines into counting passwords or malware databases could make them ill-prepared to prevent computer intrusions. Windows servers may not be smart enough to detect machine intrusions and software hackers would need software engineers with
