Background for this topic.
Identity and Access Management (IAM) is the set of processes and systems that create and manage digital identities, verify who or what is requesting access, and decide which resources it may use. It covers people, services, applications, and devices across their lifecycle, including account creation, role changes, and removal. Authentication establishes identity; authorization applies permissions.
IAM is a primary control against unauthorized access: stolen credentials, compromised service accounts, or excessive and abandoned permissions can expose systems and data or enable an attacker to move between them. Effective practice combines phishing-resistant multifactor authentication for sensitive access, least privilege through roles or attributes, prompt joiner–mover–leaver changes, and periodic access reviews. Centralized logs and alerts for unusual authentication or privilege changes support investigation, while carefully governed federation and machine identities prevent one compromised trust relationship from granting broad access.
Benny Porat of Twine Security on Automating IAM With AI, Trusting Digital AgentsTraditional IAM tools fall short in today's complex identity landscape. Twine Security's AI agent "Alex" steps in - not just automating, but acting with business context to tackle IAM tasks. It's not more tools we need, but agents who know how to use them.
