Security Audit

An IT security audit is an overall assessment of the organization’s security practices both physical and non-physical (software) that can potentially lead to its compromise if exploited by cybercriminals.

Security Audits Life Cycle

An IT security audit is an overall assessment of the organization’s security practices both physical and non-physical (software) that can potentially lead to its compromise if exploited by cybercriminals.

Plan

Senior management, as well as stakeholders and department heads, should be involved. Information security is not simply an IT issue; in order to have a robust information security program, the entire organization must be on board. Form a committee and agree on a course of action.

Do

Assign precise responsibilities to people, as well as dates and intended outcomes. Create a “cookbook” that outlines rules, standards, processes, and guidelines for maintaining a robust information security program. Portions of your information security program may change over time, just as parts of “recipes” may alter.

Check

Examine the audit findings after the remedies have been applied to see if the desired outcomes have been attained.

Act

These activities should be based on the findings of your audit, with any necessary revisions made. 
Return to the Planning phase and repeat the process until the threat has been decreased to a manageable level.

How It Works

Projects are frequently handled using a lifecycle model in all areas of IT, in which a product goes through a cycle of improvement and upkeep with no terminus. This holds true for information security just as much as it does for any other IT field.

For security professionals, the information security lifecycle acts as a key framework for day-to-day operations. Understanding the information security lifecycle model provides professionals with a roadmap for ensuring continual, evolutionary growth in a company’s information security.

Many IT management standards use the PDCA framework.
The ISO 2700x set of information security management standards is a PDCA implementation that is extremely significant to privacy management.

Plan

The company objectives are identified in the Plan phase.
The ISMS’s scope is determined, and management support is gained.
Risk analysis methodologies are chosen, and a suitable inventory of assets at risk is created, complete with rated risk evaluations.

Do
The Do phase handles risks by developing a risk treatment plan, providing resources, educating employees, and establishing policies.

Check
The Check phase evaluates the security management activities’ implementation and, if necessary, prepares for certification of the results.

Act
Our re-assessment audits in the Act phase examine the overall outcome of the corrective actions and, if necessary, launch a new round of the cycle with corrective input.
