ACLs (Access Control Lists)

Access Control Lists (ACLs) are tools used in computer networks and systems to specify which users or devices can access certain resources, such as files, directories, or network services. Think of an ACL as a permission list: it defines who is allowed or blocked from viewing, editing, or using those resources. By setting these rules, organizations can control security and ensure that only authorized individuals or systems interact with sensitive data or systems, helping prevent unauthorized access and potential security breaches.
