Cybersecurity Audit Cybersecurity-Audit-Certificate Isaca Study Notes

The FIRST phase of the ISACA framework for auditors reviewing cryptographic environments is inventory and discovery. This is because the inventory and discovery phase helps auditors to identify and document the scope, objectives, and approach of the audit, as well as the cryptographic assets, systems, processes, and stakeholders involved in the cryptographic environment. The inventory and discovery phase also helps auditors to assess the maturity and effectiveness of the cryptographic governance and management within the organization. The other phases are not the first phase of the ISACA framework for auditors reviewing cryptographic environments, but rather follow after the inventory and discovery phase, such as evaluation of implementation details (A), hands-on testing (B), or risk-based shakeout C.

In a teaming exercise, the purple team is responsible for integrating the defensive tactics and controls from the blue team (defensive) with the threats and vulnerabilities found by the red team (attacking). The purple team’s role is to ensure that the defense mechanisms are effective against the identified threats and to improve the overall security posture of the organization. They work collaboratively with both the red and blue teams to provide a comprehensive view of the organization’s security readiness1.

References: The concept of red, blue, and purple teams in cybersecurity is well-documented in ISACA’s resources. The purple team is described as a group of cybersecurity professionals who play the roles of both the red team and blue team in an ongoing and integrated manner. Their objective is to provide reliable cyber assurance by collecting intelligence on tactics, techniques, and procedures (TTPs) used by adversaries (as a red team) and then analyzing these TTPs to configure, tune, and improve the incident detection and response capability (as a blue team)1.

A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It establishes a barrier between a secure internal network and an untrusted external network, such as the internet. This system is designed to prevent unauthorized access to or from private networks and is a fundamental piece of a comprehensive security framework for any organization.

References: The concept of a firewall as a system that enforces a boundary between networks is well-established in cybersecurity literature. It is recognized as a critical component for protecting network resources by filtering traffic and blocking unauthorized access while allowing legitimate communication to pass123.

 Imaging is the process used by an IS auditor to create a bit-for-bit copy of data. This method ensures that an exact replica of the data is made, preserving all the information in the same structure and format as the original. Imaging is essential for tasks such as digital forensics, where maintaining the integrity of the data is critical.

References: The Cybersecurity Audit resources by ISACA cover the importance of accurate data replication in the context of an audit. Imaging is a standard practice in cybersecurity audits for preserving the state of data at a specific point in time, which is crucial for any subsequent analysis or investigation1.
