Configuration audit and cloud security assessment

Checking that your infrastructure uses modern security best practices

The security and confidentiality of an organisation’s information systems are safeguarded by technological and operational security measures, which are assessed through a cloud security audit.

What is a Cloud Security Audit?

A cloud audit scrutinises a cloud infrastructure and is usually carried out by an impartial third party. The auditor collects evidence during an audit by questioning, observation, testing, analytics, and a combination of these methods.

Cloud security audits primarily focus on a business’s security controls, which are the operational, administrative, and technological safeguards an organisation employs to ensure confidentiality, integrity, and availability of its information systems. An auditor can assess security measures in the cloud, whether they are deployed appropriately, if they are operating as intended, and how well they minimise risks.

The Importance and Benefits

Using the cloud poses certain security hazards. Regularly evaluating the security of your cloud infrastructure and the data kept there is essential for several reasons.

Evaluating cloud security helps to:

  • Ensure that rules and standards are followed;
  • Analyse the availability, integrity, and confidentiality of data;
  • Analyse the efficiency of security precautions;
  • Detect intrusions, abuses, and other security incidents;
  • Reduce security risks by eliminating vulnerabilities.

A security audit can verify that access control is designed correctly and user rights and privileges are managed appropriately.

Additionally, the audit can help confirm that staff members and other users use cloud services safely. Most cloud systems employ a wide range of third-party technologies and APIs. Every API and third-party tool carries the risk of compromising security. Audits can identify security flaws in tools and APIs and assist the company in fixing them.

Cloud Security Audit Challenges

Several obstacles might render cloud security audits particularly challenging.

Most of the investigative and operational data in a cloud system is under the control of cloud providers. For auditing purposes, these data are crucial. Audits must have direct access to relevant analytical information, access to security policies, and a thorough assessment of cloud resources
Multiple environments frequently share the same physical domains in a cloud infrastructure. As a result, security risks arise, and it becomes more challenging to evaluate the physical setting. If running services on physically distinct machines is not viable, the cloud hosting must demonstrate that it can prohibit any user from obtaining administrator capabilities on the unit.
Scale, Scope, and Complexity
A conventional data center had a limited number of servers, allowing auditors to examine and report on them. The number of audited entities in cloud infrastructure, however, can expand rapidly. Auditing all of these entities can be exceedingly challenging, especially when new entities are constantly being added and withdrawn. Standardising workloads is the essential component of making a cloud service auditable.

A security configuration audit is an evaluation process that helps to identify and assess potential security vulnerabilities within an organization's IT infrastructure. The goal of a security configuration audit is to ensure that all systems and devices are properly configured to meet the organization's security policies and standards.

During a security configuration audit, an auditor typically reviews system configurations and settings for various components, including servers, network devices, databases, and applications. The auditor will compare the configurations against the organization's security policies and standards to identify any deviations, weaknesses, or potential vulnerabilities.

Once the audit is completed, the auditor provides a report outlining the findings, including recommendations for remediation. The organization can then use this information to improve its security posture and reduce the risk of security breaches and data loss.

Auditing configurations typically involves the following steps:

Define the scope: Determine the scope of the audit, including which systems and devices will be audited.

Identify applicable security policies and standards: Identify the security policies and standards that apply to the systems and devices being audited.

Gather information: Collect information about the systems and devices being audited, including configuration settings and logs.

Analyze the information: Analyze the information collected to identify any deviations from the security policies and standards.

Verify findings: Verify the findings by testing the configurations and settings to confirm the identified vulnerabilities.

Report findings and recommendations: Prepare a report of the findings and recommendations for remediation, including prioritization of issues based on severity.

Implement remediation: Work with stakeholders to implement the recommended remediation actions.

Re-audit: After the remediation actions have been implemented, re-audit the systems and devices to verify that the vulnerabilities have been addressed.

It's important to note that the specific steps involved in auditing configurations may vary depending on the systems and devices being audited and the scope of the audit. It's also important to ensure that the audit is conducted by a qualified and experienced auditor.
