How to fix - Sensitive Data Exposure

Sensitive data exposure is a type of web application vulnerability that occurs when sensitive information, such as personal information, financial information, or login credentials, is transmitted or stored in an insecure manner. This can include sending sensitive information over an unencrypted connection, storing sensitive information in clear text, or using weak encryption methods. To fix sensitive data exposure, web applications should follow best practices for securely storing and transmitting sensitive information. This can include:

  • Using encryption to protect sensitive information both in transit and at rest

  • Using secure protocols such as HTTPS to transmit sensitive information

  • Using salted and hashed password storage to protect login credentials

  • Implementing secure session management to prevent session hijacking

  • Limiting access to sensitive information to only authorized personnel

It is also important to use security best practices and perform regular security assessments to identify and remediate vulnerabilities in the application. In addition, it is important to keep the web server and web application software up-to-date, as many vulnerabilities are discovered and patched by software vendors. It's also important to comply with regulations and standards such as PCI-DSS, HIPAA, and GDPR that have specific requirements for handling sensitive data.
