IT Security PolicynounMWEThe “documentation of IT security decisions” in an organization.

These policies are likely to require more frequent revision as changes in technology and related factors take place. 3) System-Specific Policies—address individual systems, such as establishing an access control list or in training users as to what system actions are permitted. These policies may vary from system to system within the same organization. In addition, policy may refer to entirely different matters, such as the specific managerial decisions setting an organization’s electronic mail (email) policy or fax security policy.Requirement

The skills acquired during training are built upon the awareness foundation, in particular, upon the security basics and literacy material.Process
