Essential Insights Identity Risks Dominate Cloud Security: A report from ReliaQuest reveals that 44% of valid cloud security alerts stem from identity-related vulnerabilities, highlighting the urgency of addressing these risks. Shift in Security Strategy Needed: Organizations must treat identity as the modern security perimeter, adopting proactive measures such as dark web scans for compromised credentials and enhancing access controls. Privilege Management is Critical: Over 99% of cloud identities are over-privileged, necessitating a zero standing privileges approach to minimize identity-based attack risks. Operational Challenges for Security Teams: The overwhelming volume of identity alerts strains security resources, increasing operational costs and complexity…
