That said, it is imperative for a business to be proactive in addressing any such potential threats and attacks and have an effective cybersecurity strategy in place. This is exactly when and where an IT security audit can be helpful. A good amount of threats can be deterred by establishing a strong defense system against cyber-crime.

Covering more on this particular aspect in detail we have shared 10 reasons why Information Security Audit is important for businesses.

What is Information Security Audit?

Information Security Audit is an evaluation process that assesses an organization’s established security practices. It is a process that determines the effectiveness of the defense systems established against any threats. The Information Security Audit typically includes vulnerability scans, penetration testing, network assessments, and much more that help determines vulnerabilities and security loopholes in the IT systems. The audit is a combination of administrative, physical hardware, software application, and network assessment. This way, the evaluation process can help a company/organization gain an understanding of its current security posture.

Addressing the growing need for strong IT security standards governing bodies and regulators from around the world have established a robust Information Security Standard which is a mandate in their region. While some of them apply broadly to the entire IT industry, many Information Security Audit standards that are developed are industry-specific. So here is a list of some very popular Information Security Audit Standards in the industry.
ISO Compliance: The International Organization for Standardization (ISO) provides guidelines for organizations that ensure the security, reliability, availability of IT infrastructure. The ISO/IEC 27001 which is known for its Information Security Management system requirements is a very popular and widely accepted international standard for Information Security.
HIPAA Security Rule: The HIPAA Compliance comprising of the Security Rules specify requirements pertaining to the methods or techniques an organization is expected to adopt to protect patients’ Personal Health Information (PHI) or (ePHI).
PCI DSS Compliance: PCI DSS compliance standard applies to organizations dealing with the payment card data of the customer. This standard is designed to ensure the protection of payment card data involving online payment transactions.
