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).
Controlling threats to computer system security of an organization
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.

Conclusion
In conclusion, without having threats protection and control system no company can survive
in the marketplace. Additionally, the execution of effective controls as well as safeguards is
an on-going process, while the efficacy of controls at a particular point of time is the meter of
the overall secure information system. In order to react effectually on changing
vulnerabilities, business processes and conditions and new technologies, threats controlling
schemes are mandatory. Hence, above prevention, detection and compensation programs help
to audit, review, and update safeguards and controls on a routine basis for an organization.
Information system security controls are the product, technical, administrative, and physical
and policy defence tools designed to guard sensitive information. Thus, all organizations
should review and re-evaluate its information security controlling programs on a regular basis
to define any essential adjustments to any of its modules.
