Introduction
This report is describing various types of Control programs which should be used in an
organisation for effective operation. The main challenge for any organization is to define the
correct set of information and personnel security controls, that if get implemented and
defined to be effective in their application, mitigate the impact of each found threat.
Additionally, for each specified security class, a range of controls are essential for a complete
and strong security frame (Legg et al., 2015).
Moreover, the chief factor that will affect the selection of threat controls is a risk-based cost
or profit analysis (The Economic Times, 2018). Another factor includes ease of use,
compatibility with present controls, and transparency to operators. Thus, controls finding
action is an organizational wide exercise, which explains the protection necessities for the
diverse classes of info. However data as well as info owners are eventually accountable
persons for the accurate working of information security controls (Wall, 2018).

Type of controls
Three main types express the key goals of operative security implementation:
■ Physical Controls Security (PCS): control procedures, devices, and ways to control
physical entree to a definite system structure
■ Technical Controls Technology (TCT): control measures to control analytical access to
sensitive data
■ Administrative Controls: control policies, methods, and business processes to describe and
guide operator actions as well as restrictions while dealing with sensitive data
Moreover, above control actions can be further categorized into following:
■ Preventive controls limit the possibility of a threat by preventing intended or unintended
and unauthorized exposure of sensitive info.
■ Detective controls identify and report tried unauthorized attempts by anyone

■ Corrective controls counter security violation incidents and end harmful happenings or
minimize their destruction.
