Thanks for signing up! assignments, emergency procedures, regulations governing equipment What level of illumination does NIST recommend for the lighting of critical areas? Effective computer security therefore involves taking physical security measures (to ensure hardware and media are not stolen or damaged), minimising the risk and implications of error, failure or loss (for example by developing a resilient back-up strategy), appropriate user authentication (for example by employing strong passwording), and possibly the encryption of sensitive files. However, effective security should plan for what happens if these measures fail, and how data confidentiality can be protected even if computer equipment or media fall into the wrong hands. He has advised you to investigate the purchase and installation of new exterior lighting.
