Restrictive and unjustified security measures especially those not based on a security policy can lower productivity of human and performance of technology components of a business. Implementing effective security requires careful design, and a need analysis and detailed risk analysis should be done first. Such assessments are then followed up with an implementation plan, where organizational communication, policy, maintenance plans, training and deployment are considered (to name a few)."
