User Account Controls

5 minutes 5 Questions

User Account Controls (UAC) is a feature present in modern operating systems, designed to help protect the system from unauthorized changes and potential security threats. UAC works by restricting applications and processes to run with the least possible permissions, enforcing them to request elevated permissions when needed. When an application or process attempts to perform an action that requires administrative privileges, such as modifying system settings or installing software, UAC prompts the user to grant or deny approval. This security mechanism prevents software from making unauthorized changes to the system without user intervention and helps block malware from gaining escalated privileges. It is important to educate users about the significance of UAC prompts and train them to make informed decisions when granting or denying permissions.

Guide: Understanding User Account Controls

User Account Controls (UAC) is a crucial feature in Windows operating systems that help enhance the overall security of a system.

What is it and why it is important:
UAC is a security component designed by Microsoft for its Windows operating systems. It helps prevent unauthorized changes to the system by asking for permission or an administrator's credentials before allowing specific tasks to be carried out. This prevents viruses or potentially malicious software from making significant changes to your computer without your awareness. It is crucial for ensuring security and data integrity on the operating system.

How it works:
Whenever an action is initiated, which affects the system, UAC pauses the process and alerts the user. The user will then need to give consent to the operation or enter an admin password to proceed. It essentially works as a gatekeeper, preventing unwanted changes from occurring.

Exam Tips: Answering Questions on User Account Controls: Understand the concept: Be clear about what UAC is and how it protects the system by restricting unauthorized changes. Know the process: Understand how UAC prompts the user or asks for an administrator's credentials when a process is initiated that impacts the system. Practice commonly asked questions: Familiarize yourself with usual exam questions relating to UAC and its functions to ensure you're well prepared.

Question 1

A company needs to ensure that all users must change their passwords every 60 days. Which User Account Control should be set?

Password complexity Password expiration Minimum password age Account lockout

Correct Answer: Password expiration

Password expiration ensures that users must change their passwords periodically. In this scenario, a 60-day cycle should be set to the password expiration. Other options focus on different aspects of user account security.

Question 2

An organization would like to prevent users from creating passwords that are too short or contain easily guessed information. Which User Account Control setting should be configured?

Account lockout Minimum password age Password expiration Password complexity

Correct Answer: Password complexity

Password complexity ensures that users create passwords that follow specific rules, such as including a combination of uppercase and lowercase letters, numbers, and special characters. This makes passwords more challenging for unauthorized individuals to guess.

Question 3

A user complains that they cannot log in to their account after entering the incorrect password multiple times. Which User Account Control setting would cause this?

Password complexity Minimum password age Password expiration Account lockout

Correct Answer: Account lockout

Account lockout is the User Account Control setting that disables user access to the account after a certain number of unsuccessful login attempts. This helps prevent unauthorized users from guessing passwords.
