Security management

Security management is the identification of an organization's assets (including information assets), followed by the development, documentation, and implementation of policies and procedures for protecting these assets.

An organisation uses such security management procedures as information classification, risk assessment, and risk analysis to identify threats, categorise assets, and rate system vulnerabilities so that they can implement effective controls.[1]

Loss prevention[edit]

Loss prevention focuses on what your critical assets are and how you are going to protect them. A key component to loss prevention is assessing the potential threats to the successful achievement of the goal. This must include the potential opportunities that further the object (why take the risk unless there's an upside?) Balance probability and impact determine and implement measures to minimize or eliminate those threats.

Security risk management[edit]

Management of security risks applies the principles of risk management to the management of security threats. It consists of identifying threats (or risk causes), assessing the effectiveness of existing controls to face those threats, determining the risks' consequence(s), prioritising the risks by rating the likelihood and impact, classifying the type of risk and selecting and appropriate risk option or risk response.

Types of security threats[edit]

External[edit]

  • Strategic: like competition and customer demand...
  • Operational: Regulation, suppliers, contracts
  • Financial: FX, credit
  • Hazard: Natural disaster, cyber, external criminal act
  • Compliance: new regulatory or legal requirements are introduced, or existing ones are changed, exposing the organisation to a non-compliance risk if measures are not taken to ensure compliance

Internal[edit]

  • Strategic: R&D
  • Operational: Systems and process (H&R, Payroll)
  • Financial: Liquidity, cash flow
  • Hazard: Safety and security; employees and equipment
  • Compliance: Actual or potential changes in the organisation's systems, processes, suppliers, etc. may create exposure to a legal or regulatory non-compliance.

Risk options[edit]

Risk avoidance[edit]

The first choice to be considered. The possibility of eliminating the existence of criminal opportunity or avoiding the creation of such an opportunity is always the best solution, when additional considerations or factors are not created as a result of this action that would create a greater risk. As an example, removing all the cash from a retail outlet would eliminate the opportunity for stealing the cash–but it would also eliminate the ability to conduct business.

Risk reduction[edit]

When avoiding or eliminating the criminal opportunity conflicts with the ability to conduct business, the next step is the reduction of the opportunity and potential loss to the lowest level consistent with the function of the business. In the example above, the application of risk reduction might result in the business keeping only enough cash on hand for one day’s operation.

Risk spreading[edit]

Assets that remain exposed after the application of reduction and avoidance are the subjects of risk spreading. This is the concept that limits loss or potential losses by exposing the perpetrator to the probability of detection and apprehension prior to the consummation of the crime through the application of perimeter lighting, barred windows and intrusion detection systems. The idea here is to reduce the time available to steal assets and escape without apprehension.

Risk transfer[edit]

Transferring risks to other alternatives when those risks have not been reduced to acceptable levels. The two primary methods of accomplishing risk transfer are to insure the assets or raise prices to cover the loss in the event of a criminal act. Generally speaking, when the first three steps have been properly applied, the cost of transferring risks are much lower.

Risk acceptance[edit]

All remaining risks must simply be assumed by the business as a risk of doing business. Included with these accepted losses are deductibles which have been made as part of the insurance coverage.
