ISMS is a complete system that provides measures to secure organizational workings and assets to the optimum. With the fast growth in technology, more risk factors are involved and ISMS acts as a tool to identify:
An organization’s information assets
The threats to those assets
The vulnerabilities that might be exploited by those threats
The impact on an organization if the loss of confidentiality, integrity or availability (CIA) of any asset was to occur
Appropriate controls and implement to manage the vulnerability
It is also important for:
Establishing an effective incident management process
Validating the existence or adequacy of business continuity arrangements
Ensuring that there is an ongoing compliance and monitoring mechanism in place
Validating the adequacy of physical & environmental security arrangements
