With cascade effects in operations, maintenance, process, safety, and business, indicates, deliberately exploiting vulnerabilities to control the system can have physical ramifications. Whether this remains at a local level or reaches into external networks, the relevance of such attacks is that access into one system perhaps means access into all. The degree of damage to a firm and hence to human life might perhaps be catastrophic. In line with other office and corporate information systems, the BACS components represent major hazards endangering the confidentiality, integrity, and availability of their data and other business elements. BACS are getting more complicated as such technologically advanced solutions as the IoT are used ever more extensively. They are dispersed all across a facility using different degrees of networks and protocols. Especially for non-technical security and facility personnel, it becomes challenging to be really aware and grasp the several interrelated ex

Commonplace in today's and the future built environments and its facilities are Building Automation and Control Systems (BACS). Now embraced by all kinds of facility types, sizes and purposes, the technology and connection of BACS go much beyond simply the big or high rise commercial structure. BACS is driven commercially; a desire for more information flow and functionality across the company helps to lower running and maintenance costs. Besides, to offer a facility more time sensitive and safer. BACS are today a corporate information system, not only a convergence of plant and equipment. BACS permeate every level of a facility's communication system as well as all areas of its operations. BACS is used or depended upon by several departments, groups, and individuals working inside an organization. For instance, the role of security and related technologies is presently and will be more so absorbed into BACS. Building engineers and facility managers design and run BACS, thoug
