Golang Broken Authentication Guide: Examples and Prevention

Authentication is a crucial component in software security, designed to verify the identity of users to prevent unauthorized access and protect sensitive information. It distinguishes itself from identification by requiring proof of identity rather than merely claiming it. In software applications, particularly those built with Golang, improper implementation of authentication can lead to vulnerabilities such as session fixation, password spraying, unprotected login details, session hijacking, and rainbow table attacks. These vulnerabilities allow attackers to exploit user privileges and access confidential data. To counteract these threats, developers can implement preventive measures such as session timeouts, account locking, password strengthening, CAPTCHA usage, and adding salt to password hashes. Software tools like StackHawk can assist developers in monitoring and fixing potential vulnerabilities, ensuring robust security protocols are in place.
