Internal Security Audits 101

Auditing information security covers topics from auditing the physical security of data centers to auditing the logical security of databases and more. From this view point, add the dimension that each business is different and has its own challenges; and objectives in terms of the value they hope to gain from undergoing the process of the internal security audit.


A security audit is a systematic evaluation of the security of a company’s information system by measuring how well it conforms to a set of established criteria. A thorough audit typically assesses the security of the system’s physical configuration and environment, software, information handling processes, and user practices. Security audits are often used to determine regulatory compliance. – Techopedia


While the business value of an effective audit is not in question, the proposal of an audit is often met with resistance:  the Information Systems department (IS) vs the Auditor. The perception from the IS side is that they feel like they are being policed or deliberately being set up to be caught with their proverbial pants down. The result? The equivalent of digital hide and seek between two company departments who should actually be complementing each other’s role and objectives. Communicating the specific objective, playing open cards with each other and sharing insights of the systems in questions will eliminate conflict from the start.


There is no one-size fits all security audit


While it is important to ensure that your company has an Internal Security Policy that covers all aspects of information security, and audit should focus on one or two areas that will have the biggest impact on business. It could be a combination of any of the following areas:


  • Information Security (general)
  • Business Continuity Management
  • Mobile
  • Cloud
  • IT Risk Management
  • Programme Risk
  • Software / IT Asset Management
  • Social Media Risk Management
  • Segregation of duties / Identity and access management
  • Data loss prevention and privacy

“Effective risk management is the product of multiple layers of risk defense. Internal Audit should support the board’s need to understand the effectiveness of cybersecurity controls.”  – Deloitte.
