In today?s digital age, organizations face growing cyber threats targeting user identities and access credentials. Identity and Access Management (IAM) helps secure identities, manage privileges, and enforce security policies?making it essential for zero-trust security, compliance, and efficiency. Privileged Access Management (PAM), a specialized branch of IAM, focuses on protecting and monitoring privileged accounts such as administrators, root users, and service accounts. Because these accounts have elevated access, they are prime targets for cyberattacks. Together, IAM and PAM safeguard access to systems, applications, and data, playing a vital role in cloud security, IoT, and enterprise environments by preventing unauthorized access and mitigating insider threats. Readers will learn: ·        Why securing identities is critical today ·        Key differences between IAM and PAM ·        Major access management risks and challenges ·        Common IAM and PAM solutions (e.g., Azure AD, Okta, CyberArk, BeyondTrust, SSH Communications Security)
