OAuth Token: What It Is, How It Works, and Its Vulnerabilities
AppOmni, Wednesday, July 12,2023
Previous security breaches at Heroku and GitHub serve as stark reminders that OAuth token theft and inactive, overly permissive SaaS-to-SaaS connections represent significant security risks to any organization.
As more employees turn to SaaS apps to streamline job processes and boost productivity, they rely on OAuth to authenticate and authorize these apps with their enterprise SaaS platforms. This comes as no surprise, as OAuth's user-friendly framework allows users to access SaaS apps, which also contain data and workflows.
But this OAuth connection and associated OAuth token can also allow unguarded access to SaaS apps for extended periods of time. This is why stealing or compromising OAuth tokens is so sought after by threat actors. While OAuth is a secure framework, the improper implementation and the lack of continuous monitoring of SaaS app access, may leave your organization exposed to unnecessary security risks, which can result in incidents.
