Project Overview

A security policy is a set of vital mechanisms by which the XYZ’s security objectives can be defined and attained. These key information security objectives should consist of: Confidentiality to ensure that only the people who are authorized to have access to assigned areas are able to do so. It’s about keeping valuable information only in the hands of those people who are intended to see it. Integrity to maintain the value of logs information, which means that it is protected from unauthorized modification. Logs information only has value if we know that it’s correct. A major objective of security policies is thus to ensure that logs information in not modified or destroyed or subverted in any way. Availability to ensure that all the utilities and systems are available and operational when they are needed. A major objective of an access security policy must be to ensure that utilities information is always available to support critical business processing. The purpose of this audit is to evaluate the access and security internal controls related to the XYZ and to assess whether there are internal control weaknesses that could allow errors and irregularities to go undetected.
