What is a network security audit?

Network security audits protect organizations from security threats by uncovering underlying network security issues. An audit can isolate security threats and trace data breaches, allowing you to plug holes, restrict network access, and improve your company’s network surveillance.

So, instead of worrying about an impending network security audit, businesses should embrace the process; it’s always better to be proactive instead of reactive. Plus, it’s important to keep in mind the end goal is to improve your organization and protect your customers.

Why Are Network Security Audits So Important?

A lot of businesses only think about security and risk assessments once it’s too late– it’s after the breach or the cyberattack. There are a number of famous data breaches that stem from not only a lack of investment in IT, but a lack of an audit trail and network security to really battle against. for ex: Panera, Mariott beaches

Network security assessments can answer questions like:

• What systems are likely to be breached?
• What are the common entry points for security breaches
• What would the impact of a cyber attack be on a specific asset?
• What sensitive data, personally identifiable information, or protected health information would be exposed in a data breach or data leak?
• What can we do to mitigate this type of attack?

What are the types of network security audits?

There are two types of network security assessments:

Vulnerability assessment: A vulnerability assessment shows organizations where their weaknesses are.
Penetration test: Penetration testing is designed to mimic an actual cyber-attack or social engineering attack such as phishing, spear-phishing, or whaling.

Both are great methods to test the effectiveness of your network security defenses and measure the potential impact of an attack on specific assets.

Generic key steps for security audits

• Determine information value
• Assess IT infrastructure
• Assess risk
• Assess firewall security
• Conduct penetration tests
• Document results in a network security assessment report
• Implement security controls to improve cybersecurity
• Continuously monitor for issues and changes
