Basic Computer Hygiene

Security, like cleanliness, must be a process Security is well defined for information technology:

  • Authentication and Encryption
  • Defined and Known System
  • Least Function
  • Least Privilege
  • Backups

  • Passwords
  • Encryption
  • Identification
  • Least Privilege
  • Technology
  • Regulatory
  • Remoteness
  • Costly Change

Basic Computer Hygiene in Cyber Physical Systems

The vocabulary and technology are designed for IT security.

Human Error

Subject Matter Experts (SME) are not trained in cybersecurity, but are more aware of system anomalies.

Computer Hygiene Awareness

  • Regular inspection
  • Cross functional analysis
  • Redundancy

Training

Novel research Confidentiality, Integrity, and Availability (CIA) of systems must also support the need for stability, controllability, and observability. Authentication research at LANL, Physical Unclonable Function (PUF) Questions?
