I’ve seen firsthand the devastating effects of not having a proper control assessment process in place. From data breaches to cyber attacks, the risks are real and the consequences can be catastrophic. That’s why mastering security is so critical. But, where do you start? How do you know if your controls are effective? In this article, I’ll be sharing the four phases of effective control assessment that every organization should be implementing to safeguard against potential cyber threats. So, buckle up and let’s dive in.

What are the 4 phases of assessing security controls?

Introduction: Conducting Security Audits

In our digital age, cyber attacks have become a commonplace occurrence. The prevalence of cyber attacks has compelled businesses and organizations to take cyber security seriously. The first step to secure an organization is to conduct a thorough security assessment to identify vulnerabilities and determine how to mitigate them. A security audit is the process of assessing an organization’s security posture to identify and evaluate its vulnerabilities. Organizations conduct internal security audits to ensure that their policies and procedures are in line with best practices.

Phase 1: Preparing for the Assessment

The preparation phase of a security assessment is the foundation for the entire audit process. The key objective of this phase is to prepare the organization for the security audit. Before starting the security audit, the assessment team must get a clear understanding of the organization’s security posture, budget, and requirements. Some of the things that need to be done during the preparation phase include:

• Define the Scope of the Audit: It is essential to identify what is within the scope of the audit and what is not. By defining the scope, the assessor will know what systems and services need to be evaluated.
• Identify the Assets to be Evaluated: Determine which assets are critical to the organization and will be evaluated during the assessment process.
• Assemble the Assessment Team: A team of professionals must be assembled to undertake the security audit process. The team must be experienced in conducting security assessments.
• Notify Clients: It is essential to inform all clients about the upcoming audit. This action builds trust and credibility with clients, and they will be aware that the organization cares about its security posture.

Phase 2: Creating an Assessment Plan

The assessment plan outlines the plan of action to complete the security audit successfully. The assessor can develop a plan based on the outcome of the preparation phase. After completing the planning phase, the assessor should have a clear understanding of the organization, its assets, and the scope of the audit. Some key elements of the assessment plan include:

• Methodology: Define the methodology to be used to assess the security controls. The methodology should be based on best practices and should comply with any regulatory requirements.
• Risk Assessment: Identify the threats, vulnerabilities, and risks associated with the assets to be evaluated.
• Testing Procedures: Define a clear and concise testing procedure to ensure that all tests are completed consistently and uniformly.
• Test Deliverables: Define the expected deliverables from the test. The deliverables may include a detailed report, a list of vulnerabilities, and recommendations for improving the security posture.

Phase 3: Carrying out the Test

The test phase is where the actual assessment takes place. The assessor executes the assessment plan and evaluates the security controls in place. During this phase, the assessor should be able to identify vulnerabilities and deficiencies in the security posture. Some things to be done during the test phase include:

• Security Scans: Perform vulnerability scans to identify potential vulnerabilities or weaknesses in the organization’s security posture. The scans should be executed on all critical assets identified during the preparation phase.
• Penetration Testing: Conduct penetration testing on critical systems to verify if vulnerabilities identified during the vulnerability scans are valid.
• Social Engineering: Perform social engineering tests to determine if employees comply with the organization’s security policies.
• Interviews and Document Review: Interview employees and review the organization’s security policies, procedures, and any other relevant documents to get a comprehensive understanding of the security posture.

Phase 4: Analyzing the Results

The analysis phase is where the organization’s security posture is evaluated. The assessor reviews the test results and produces a report that summarizes the vulnerabilities discovered. The report should include detailed recommendations for improving the organization’s security posture. Some things that need to be done during the analysis phase include:

• Review and Analyze Test Results: Review the test results and identify areas of deficiency. The assessor should categorize vulnerabilities based on the risk level.
• Recommendations: Develop recommendations to address any vulnerabilities identified during the assessment. The recommendations should be prioritized based on the level of risk they pose to the organization.
• Reporting: Produce a detailed report that outlines the vulnerabilities identified and recommendations for their remediation. The report should also include a summary of the assessment process and testing methodologies used.
• Monitoring and Maintenance: Develop a plan for monitoring and maintaining the security posture to ensure that vulnerabilities are mitigated, and the organization is secure.

Importance of Security Audit in the 4 Phases

The security audit process serves as the foundation for the organization’s security posture. By conducting a thorough security audit, the organization can identify its security strengths and weaknesses and develop an action plan to improve its security posture. Regular security audits help organizations detect any potential vulnerabilities before they become exploited. A security audit helps with the following:

• Identify Weaknesses: A security audit identifies weaknesses in the organization’s security posture.
• Stay Compliant: A security audit helps organizations stay compliant with regulations and best practices.
• Prevent Cyber Attacks: By identifying and mitigating vulnerabilities, a security audit helps prevent cyber-attacks.
• Improve Reputation: By conducting regular security audits, organizations can demonstrate their commitment to cyber security, improving client relations and reputation.

Conclusion: The Need for Consistent Security Auditing

The security audit process is critical in ensuring the organization’s security posture is up-to-date and mitigating the risk of a cyber-attack. The process of conducting security audits is an easy four-step procedure: prepare for the assessment, create an assessment plan, carry out the test, and then analyze the results. By performing a periodic security audit, organizations can sustain their positive security posture and continually improve. Hackers are continually adapting their tactics, making security audits vital to maintain the organization’s security posture. By taking a proactive approach and conducting frequent assessments, organizations can keep up with the rapidly evolving security threat landscape and stay one step ahead of cybercriminals.
