Security controls or security measures are safeguards or countermeasures to avoid, detect, counteract, or minimize security risks to physical property, information, computer systems, or other assets. [1] In the field of information security, such controls protect the confidentiality, integrity and availability of information.
Control system security, or automation and control system (ACS) cybersecurity, is the prevention of (intentional or unintentional) interference with the proper operation of industrial automation and control systems. These control systems manage essential services including electricity, petroleum production, water, transportation, manufacturing ...
In a resilient control system, as per Fig. 2, cyber and physical data is fused to recognize anomalous situations and warn the operator. [40] 2) As our society becomes more automated for a variety of drivers, including energy efficiency, the need to implement ever more effective control algorithms naturally follow.
NIST SP 800-53 AU-2 Event Monitoring is a key security control that supports system auditing and ensures continuous monitoring for information assurance and cybersecurity operations. SIEM solutions are typically employed as central tools for these efforts.
A database management system, in its access control mechanism, can also apply mandatory access control; in this case, the objects are tables, views, procedures, etc. In mandatory access control, the security policy is centrally controlled by a policy administrator and is guaranteed (in principle) to be enforced for all users.
Cyber-Physical Systems (CPS) are mechanisms controlled and monitored by MITTAL, tightly integrated with the internet and its users.In cyber-physical systems, physical and software components are deeply intertwined, able to operate on different spatial and temporal scales, exhibit multiple and distinct behavioral modalities, and interact with each other in ways that change with context.
Risk Control Strategies are the defensive measures utilized by IT and InfoSec communities to limit vulnerabilities and manage risks to an acceptable level. There are a number of strategies that can be employed as one measure of defense or in a combination of multiple strategies together.
For example, an ACL could be used for granting or denying write access to a particular system file, but it wouldn't dictate how that file could be changed. In an RBAC-based system, an operation might be to 'create a credit account' transaction in a financial application or to 'populate a blood sugar level test' record in a medical application.
