-Another seemingly obvious question, but one that is frequently ignored. If the security solution doesnŐt solve the problem, itŐs no good. This is not as simple as looking at the security solution and seeing how well it works. It involves looking at how the security solution interacts with everything around it, evaluating both its operation and its failures.
