IAM systems enable the implementation of best practices like Single Sign-On (SSO) for credential management forcing users to generate stronger passwords and periodically change them. Multi-factor Authentication (MFA), a core component of IAM, ensures that user identities are confirmed beyond the initial password challenge. IAM can also mitigate the risk of insider threats by ensuring users – including privileged users and third-party vendors – have access to only those systems and applications needed to perform their tasks.
