Examples of Information Security Audit

Equifax Data Breach (2017)One of the most significant breaches involving consumer personal data, the Equifax data breach exposed sensitive information belonging to 143 million people, including Social Security numbers, home addresses, driver’s license numbers, and other personal information. Following the breach, Equifax underwent an extensive information security audit, during which investigators found that the company had failed to implement basic security measures like the patching of a critical vulnerability on their servers. This security lapse allowed hackers to access the sensitive information. As a result, Equifax faced significant financial implications and a severe blow to its reputation.

JP Morgan Chase Data Breach (2014)In mid-2014, JPMorgan Chase experienced a significant data breach that exposed sensitive information of over 83 million customers, including names, home addresses, phone numbers, and email addresses. After the breach, an information security audit was conducted to assess the root cause of the incident and identify potential vulnerabilities. It was discovered that the bank had failed to implement two-factor authentication on one of its servers, which made it easier for hackers to breach the system and steal customer data. Following this, JPMorgan Chase invested in enhancing its security measures to prevent further breaches.

Sony Pictures Hack (2014)Sony Pictures suffered a massive cyberattack in 2014, which led to the theft of unreleased movies, confidential employee data, and other sensitive company information. In addition, the attackers released some of the stolen data on the internet, causing a significant financial and reputational loss for Sony. An information security audit was conducted post the incident to identify shortcomings in the company’s security measures. It was found that poor password management and insufficient security protocols contributed to the successful hack. Sony subsequently implemented improved security measures, employee training, and information protection protocols to prevent future incidents of this nature.
