Assess your understanding of security challenges and common misconfiguration pitfalls within role-based access control (RBAC) systems. This quiz highlights essential concepts, vulnerabilities, and best practices related to RBAC security, helping you strengthen access policies and mitigate potential risks.
Which security risk is most likely to occur when users in an RBAC system are assigned more privileges than their role actually requires, such as granting account creators access to deletion functions?
Explanation: Least privilege violation happens when a user receives more permissions than necessary, increasing the risk of abuse or accidental changes. Privilege escalation refers to attacks where users gain unauthorized rights, but it often exploits misconfigurations rather than overgranting. Role sprawl is about having too many roles, not overly broad permissions in one. Password spraying is an authentication attack, unrelated to RBAC permission assignment.
What security misconfiguration can result from incorrectly assigning users to a role with higher access than intended—for example, a waiter assigned to a 'manager' role in a restaurant system?
Explanation: Broken access control occurs when users can access features or data outside their intended scope due to misassigned roles. Phishing is an external attack exploiting users, not misconfigurations. Session fixation and credential stuffing are authentication-related threats and not directly related to incorrect role assignments. Ensuring proper role assignment is key to avoiding broken access control.
What is the primary risk when using role inheritance in RBAC without thoroughly reviewing inherited permissions, such as allowing a 'supervisor' role to inherit all of 'employee' permissions plus extras?
Explanation: Unintended privilege propagation occurs when a higher role inherits more permissions than necessary, potentially exposing sensitive operations inadvertently. Brute force attacks target passwords, not RBAC inheritance. Phishing is a separate threat and token expiration relates to session management. Regularly reviewing role hierarchies prevents excessive privilege inheritance.
If a user is assigned to multiple roles with overlapping and conflicting permissions, which issue might arise in the RBAC enforcement process?
Explanation: Permission creep happens when users accumulate permissions from multiple roles over time, often unintentionally widening their access. Data encryption is unrelated to access consolidation. Time-based access expiry controls session activity, not role assignments. Single sign-on failure deals with authentication, not permission accumulation. Unchecked permission creep can lead to security gaps.
What is a potential security risk when a default role in an RBAC system includes broad access rights and is automatically applied to all new users?
Explanation: Overprivileged default access is a risk when every new user inherits more capabilities than necessary, enabling accidental or malicious actions from the start. Credential rotation relates to password management, not role defaults. Resource contention involves performance, not access rights. User enumeration is about identifying valid users, not overgranted permissions. Setting restrictive defaults is a best practice to minimize risk.
