It is important to have security; the NS-corp main frame hosts sensitive company and customer information. The NS mainframe contains train schedules, cargo information and even operational plans, and these could not be in the open. Such information may be stolen or misused, wasting time and money without good security. Protective measures include secure networks and monitoring systems, passwords, and so forth, which the mainframe uses to block suspicious entry. Even the NS mainframe login process checks identities before allowing entry. This will ensure the company's operations are safe, reliable, and trusted by customers.
