Systems and policies that determine who can access resources and what actions they can perform.
Access control is how you decide who can access a system and what they’re allowed to do. For most marketing and web teams, the risk isn’t theoretical: a compromised account can change tracking, inject spam pages, leak customer data, or spend ad budget.
Strong access control improves security and reliability - but it also improves operational clarity. When roles are clear, mistakes are less likely and changes are easier to trace.
