What Is a Cybersecurity Audit?

What Is a Cybersecurity Audit?

A cybersecurity audit is a thorough check of your organization’s security practices performed by an independent third-party auditor. The audit examines how well your cybersecurity practices, policies, and staff work together to reduce the risk of cyberattacks. 

It also helps ensure that your business can run without a hitch if any cyber incident occurs, giving you a strong basis for building solid cybersecurity risk management and disaster recovery plans. A cybersecurity audit can be a formal evaluation of your systems based on a particular framework or a readiness assessment. 

Cybersecurity compliance audits come in two forms: internal and external. 

Internal audits are carried out by your developers and security teams, often using white box testing, where they can access the source code. 

External audits, on the other hand, involve outside experts who perform penetration testing, simulating an attacker’s perspective without prior knowledge of the system.

Why Is Cybersecurity Audit Important?

Cybersecurity audits are important because they help avoid penalties by ensuring adherence to relevant laws and industry regulations. The main objective is to, of course, reduce cyber risks; however, there are other benefits also, which include:

• Verifies that relevant cybersecurity controls are in place to enforce policies and procedures
• Ensures sensitive data is secured against unauthorized access
• Increases readiness for responding to security incidents
• Reinforces trust and credibility with customers, employees, and partners
• Confirms that security policies and procedures are being followed
• Provides a thorough review of how well people and systems are adhering to security protocols
• Ensures alignment with both internal and external compliance requirements

Who Needs a Cybersecurity Audit?

A cybersecurity audit is required for organizations of all sizes to help identify and manage their cybersecurity risks. As a general rule, any organization that handles sensitive data or relies on digital systems should conduct regular cybersecurity audits.

Here are some examples of who needs a cybersecurity compliance assessment:

Industries	Examples
Financial Institutions	Banks, credit unions, and other financial services companies must protect customer financial data and comply with regulations like the PCI DSS.
Healthcare Providers	Hospitals, clinics, and healthcare organizations must secure patient data and meet HIPAA requirements.
Government Agencies	Federal, state, and local government bodies must protect classified and sensitive information and adhere to regulations such as FISMA.
Defense Contractors	Companies working with the Department of Defense must meet strict cybersecurity requirements like those outlined in the CMMC
Tech Companies	Software developers, cloud service providers, and IT companies must ensure the security of their systems and services and meet industry standards like SOC 2 or ISO 27001.

How Often Should You Implement Cybersecurity Audits?

For instance, industries regulated by PCI DSS, SOC 2, HIPAA, or GDPR often require annual security audits to maintain data protection standards.

Critical Steps to Prepare for a Cybersecurity Audit

Preparing for a cybersecurity audit usually starts with understanding the scope, reviewing security policies, and more. Choosing the most appropriate audit to conduct for the first time can be difficult.

When asked for one of the best cybersecurity audits to start with, I.S. Partners shares this wisdom,

We have broken down the key steps with a cybersecurity audit example to make the audit much more manageable. 

Step 1. Understand the Scope of the Audit

Understanding the scope of your audit is key to a smooth process. Start by defining what you want to achieve and how it aligns with your business goals. 

Figure out which systems, processes, and data will be reviewed. For example, if your audit concerns cloud security, pinpoint the cloud services, data types like customer info, and processes such as data storage that will be assessed. 

This will allow you to focus on the most important areas and avoid surprises.

Step 2. Review and Update Your Security Policies

Security policies are living documents—they should evolve with your organization. Many people assume policies are set in stone but need regular updates to stay relevant. 

If it’s been a while since you last reviewed your security policies, they might be outdated or not in accordance with current laws, regulations, or technology. Revisit and update them to match your security goals, best practices, and compliance needs.

Step 3. Implement Security Controls

Implementing strong security controls is key to protecting your organization from cyber threats. These controls range from technical safeguards like encryption and firewalls to access restrictions and monitoring systems.

There are two types of controls you can implement, and they are:

Physical controls are the tangible measures to secure your physical spaces and assets. This includes fences, gates, security badges, biometric access, CCTVs, and even environmental systems like HVAC.

Technical or logical controls involve hardware or software tools that protect your digital assets. Examples include firewalls, antivirus software, authentication systems, intrusion detection systems (IDS), and encryption protocols.

Step 4. Determine Whether the Audit Will Be Conducted Internally or Externally

Decide whether you want the audit done by your team or an independent firm.

• Internal Audit. This is carried out by your in-house employees or departments, like HR or compliance. It improves your company’s performance and ensures adequate internal controls. The results are usually summarized in an internal report.
• External Audit. This type of audit is handled by outside auditors who are not part of your company. They assess your company’s performance and the accuracy of financial statements, leading to an external audit report. If you meet the criteria, you will get a certificate.

Step 5. Conduct a Pre-Audit Assessment

Carry out a pre-audit assessment to get a head start on your certification process. This step helps you understand the audit procedure and gives you an external perspective on your current management system.

One way we do it at I.S. Partners is through readiness assessments. A readiness assessment is a pre-check for your cybersecurity audit. It’s a way to see how prepared your organization is before appearing for the official audit. 

Here’s what happens during a readiness assessment:

1. Gap Analysis. We compare your current processes, policies, and procedures with the specific cybersecurity audit requirements. This helps us spot any areas that might need a little extra attention.
2. Document Review. We review your documentation—such as procedures, records, and policies—to ensure that everything is in order and up to standard.
3. Process Evaluation. We examine closely how your cybersecurity processes meet cybersecurity requirements, looking for inconsistencies or inefficiencies.
4. Risk Identification. We identify potential risks affecting your certification process and assess how well your organization handles them.
5. Action Plan Development. Based on our findings, we’ll give you recommendations and a roadmap to address any gaps so you’re ready for the official audit.

Step 6. Gather Necessary Documentation

Get all the necessary documentation ready for the audit, including security policies, risk assessments, compliance records, and logs. Organizing these materials ahead of time will make the audit process smoother. 

Also, make sure you have everything—from incident response plans to data breach notifications and technical documents—compiled into an easy-to-use document or spreadsheet.

Step 7. Conduct Regular Vulnerability Scans and Penetration Tests

Regular vulnerability scans and penetration tests are key to securing your network and applications. Vulnerability scans act as an early warning system, catching potential issues that can be done weekly, monthly, or quarterly. 

Penetration tests take it a step further by simulating real attacks to expose specific weaknesses. Together, these practices help identify and fix vulnerabilities so that your security controls are effective defenses against cyber threats.

Step 8. Choose a Good Auditor for Your Cybersecurity Audit

When it comes to picking the right auditor for your cybersecurity audit, you need to weigh their value and fit for your specific needs:

• Start by checking their pricing. Are they transparent and reasonable about what they offer? 
• Look closely at the contract terms to ensure everything is clear. 
• Think about what you’ll get from the audit—will the results help you boost your data security and meet compliance standards? 
• You’ll want an auditor who gives you a detailed, actionable report and provides ongoing support to help you keep improving.

Step 9. Communicate With Auditors

Maintain open lines of communication with the auditors before, during, and after the audit. Clarify any questions about the audit scope, provide necessary information promptly, and seek feedback to improve your security practices.

Also, employees must be on standby to support the audit team. This ensures that knowledgeable staff members are ready to step in and keep the process running without interruptions if someone on the audit team is unavailable or needs assistance.

Step 10. Maintain Ongoing Compliance

After successfully completing your cybersecurity audit, the work doesn’t stop there. Maintaining ongoing compliance is crucial to ensure that your organization continues to meet security standards and stays ahead of evolving threats. Compliance isn’t a one-time achievement but a continuous process that requires regular monitoring, updating, and improving your security controls and practices.

Regularly review and update your security policies to reflect changes in your organization, technology, or regulatory requirements. Implement a continuous monitoring program to track your security posture and quickly identify and address vulnerabilities.

Here is a simple assessment you can take up to choose the right cybersecurity for your company:

How to Choose the Right Cybersecurity Auditor?

To choose the right cybersecurity auditor for your auditing needs, there are a few factors to consider, like qualifications, expertise, and customer support. Let’s take a look at them in detail:

Qualifications and Expertise

You need a team with a proven track record in cybersecurity audits, particularly in the frameworks and regulations that matter to your industry—SOC 2, HIPAA, PCI DSS, or ISO 27001. A firm with experience across different sectors can bring a broader perspective on physical security challenges.

For instance, I.S. Partners specializes in IT compliance and risk advisory, offering solutions like SOC, PCI DSS, and HITRUST examinations. With certifications like CPA, CISA, CISSP, and CIA, they have the credentials to back up their expertise.

Time Commitment

Client Support

Lastly, outstanding client support is critical. Look for a firm that truly understands your company’s mission, values, and business objectives and is willing to customize its approach to fit your unique needs. 

It’s important to get to know the assessors who will handle your account, as well as the senior leadership, so you can gauge how well their team will collaborate with yours to build a strong, lasting partnership.
