What Features Should You Look for in a Security Audit Tool?

1. Comprehensive Vulnerability Scanning

The tool should be able to continuously monitor and scan assets to find hidden or new vulnerabilities. Using automated scanning often, you can detect vulnerabilities that arise post-pentest and with every software update or feature addition.

A scanner integrated into your CI/CD pipeline would make it convenient to conduct continuous tests.

2. Pentesting

The security audit provider should be able to conduct continuous pentests to assess an organization’s security posture regularly and find vulnerabilities that quick scans could’ve missed.

Based on the target organization’s initial scope and needs, it should deploy its automated scanner combined with manual pentesting efforts to find its security flaws.

3. Detailed Audit Report

Detailed audit reports are an essential feature of security audit tools as they help customers make fixes based on risk priority. It should also include detailed remediation steps for patching each vulnerability within the report and their CVSS scores. 

It would also be helpful to have an audit provider that offers customizable reports tailored to the level of technicality the reader requires. For example, this would be different for a CTO vs. a security engineer.

4. Remediation Support

They should be able to provide expert assistance with vulnerability remediation for your organization’s security. 

This includes supplying POC videos, immediate query clearance, detailed steps within the security audit report, and prioritized remediation plans based on risk assessment.

5. Compliance-Specific Scan

Compliance-specific scans can help your organization achieve and maintain the compliances it requires in a completely hassle-free manner.  It conducts compliance checks for GDPR, HIPAA, PCI-DSS, ISO 27001, and SOC2. 

A dashboard devoted to compliance can help you choose the compliance you want to scan for based on which the scan detects any and every non-compliance that needs to be remedied. 

Types Of Security Audit 

1. Network Security Audit 

Network security is an integral part of overall IT security. Employing network security audit tools to conduct audits regularly is very important, as networks usually see high data transfer and storage activity. 

This involves examining devices like routers, switches, firewalls, and servers for vulnerabilities, misconfigurations, and unauthorized access points. Organizations can protect sensitive data from breaches, unauthorized access, and denial-of-service (DoS) attacks by identifying weaknesses in network security.

2. Web Application Security Audit

Web security audit tools help identify vulnerabilities and loopholes in web applications before they can be exploited. This staves off various threats, like DDoS attacks, and can even help find business logic errors. 

These audits examine the application’s code, infrastructure, and functionality to find weaknesses such as SQL injection, cross-site scripting (XSS), and other common vulnerabilities. 

3. Cloud Security Audit 

Cloud security audit tools scan cloud servers, where copious amounts of data and applications are stored and transmitted. Cloud server providers should conduct regular audits to ensure all vulnerabilities are found and fixed. 

These audits assess cloud environments’ configuration, access controls, data protection measures, and overall security posture. 

Essential Steps In A Security Audit

1. Define Scope

This is the initial phase of the audit, where the security audit provider and the customer agree upon a scope detailing the number of assets to be audited, the rules of attack, and the understanding of the client’s needs. Proper scoping is required for a thorough security audit to avoid scope creep and legal troubles. 

2. Scan Assets

This is the second phase of a security audit, where the organization’s assets are scanned for any vulnerabilities or areas of non-compliance using automated security audit tools. Open-source and freely available security audit tools can be used for this task. 

3. Risk Evaluation

The vulnerabilities discovered are categorized based on the threat’s severity. This is usually based on CVSS (Common Vulnerability Scoring System) scores, in which 8-10 represents critical vulnerabilities, 5-7 medium-level vulnerabilities, and 1- 4 low-level vulnerabilities.

4. Audit Report

Once the security audit provider completes the security audit, it generates a detailed audit report for the customers to help them understand the measures taken, vulnerabilities found, remediation measures that can be opted and help with good documentation of security. 

5. Remediation

The audit report will contain remediation measures for the vulnerabilities found on them. These vulnerabilities are to be remediated and patched based on criticality; the ones with high criticality should be patched immediately. 

Final Thoughts

Security audits are in increasing demand from most compliance departments, and customers are beginning to see value in maintaining high levels of security. They help assure the quality of your security system, increase trust in your brand, and also help achieve compliance. 

These audits require systematically assessing networks, systems, and applications to identify vulnerabilities and establish countermeasures for securing sensitive data.

The rising incidences of data breaches solidify the importance of strong security measures. This article discusses some critical features to consider in a security audit tool, including penetration testing, automated scanning, and remediation support. 

We have compared and contrasted the top seven security audit tools so you can evaluate your needs and make the right choice. Our top three picks would be Astra Security, Palo Alto Networks, and Qualys. Ultimately, choosing the right security audit tool depends on the customer’s budget, organizational size, industry, and specific security requirements.
