Trusted Security Advisor Services.

What are Trusted Security Advisor (TSA) services?

As organisations become more reliant on information technology, they face a multitude of challenges in ensuring the data held or processed by the organisation is secure from unauthorised disclosure or modification and available to the right people when they need it. Both the public and private sector are subjected to legislation such as the Data Protection Act, Industry standards such as PCI DSS and ISO/IEC 27001 and sector specific standards such as the Cabinet Office Security Policy Framework (SPF) for government agencies.

Information security projects often fail to deliver the results expected by the business due to a number of issues including: Security requirements driven by the IT department rather than by the business;

  • Lack of a clear strategy for information security;
  • Lack of management buy in;
  • Data assets are not identified or valued;
  • Poor security awareness within the organisation;
  • Poor security culture;

As a result, businesses tend to either over protect data assets by applying a blanket approach to security or not protect them enough by not identifying the critical assets.

Effective security is a risk based mechanism. Security controls must be applied in a proportionate and appropriate manner based on a risk assessment.

In order to manage risks effectively, information security must be properly integrated into business management such that it adds value to the business throughout the life cycle of the information systems containing the data.
