Jump to Tutorial Advanced Package Tool (APT) is the backbone of package management on Debian and Ubuntu systems. It simplifies the process of installing, updating, and removing software. APT works with repositories — designated locations that host packages and update information.

Identity and access management (IAM) provides a consistent, centralized solution to manage user identities and automate access control throughout the organization. This helps security leaders introduce role-based access control and meet governance, risk, and compliance goals. Your organization may already have centralized management policies in place. For example, requiring employees to use a VPN when accessing company assets remotely shows an IAM solution in action.

Get it wrong, and you’ve instantly tarnished a new hire’s experience — or worse, opened the door to security and compliance violations. With so much riding on this one component of IT or MSP work, organizations of any size need to be judicious about the identity and access management (IAM) tools they select.
