Question 1

What is the purpose of multifactor authentication?

Accepted Answer

Require multiple credentials

Answer

Multifactor authentication (MFA) enhances security by requiring users to provide two or more different types of credentials from independent categories to verify their identity. These categories typically include something you know (like a password), something you have (like a phone or token), and something you are (like a fingerprint). This layered approach significantly reduces the risk of unauthorized access, even if one factor is compromised, making it much harder for attackers to gain entry.

Question 2

What protocol is used to securely browse websites?

Accepted Answer

HTTPS

Answer

HTTPS (Hypertext Transfer Protocol Secure) is the secure version of HTTP, the protocol over which data is sent between your browser and the website you are connecting to. It encrypts the communication between the client and the server using SSL/TLS, protecting data from eavesdropping and tampering. This ensures the confidentiality and integrity of information exchanged, making it safe for sensitive transactions like online banking or shopping.

Question 3

What does WPA3 secure?

Accepted Answer

Wireless networks

Answer

WPA3 (Wi-Fi Protected Access 3) is the latest security standard for wireless networks, designed to provide stronger encryption and more robust authentication than its predecessors. It offers enhanced protection against brute-force attacks and improves privacy for users on public Wi-Fi networks. WPA3 secures the data transmitted over Wi-Fi, making it much harder for unauthorized parties to intercept or decrypt communications.

Question 4

What is the main function of a firewall?

Accepted Answer

Control traffic

Answer

A firewall acts as a security barrier, monitoring and controlling incoming and outgoing network traffic based on predefined security rules. Its main function is to permit or deny data packets, protecting a private network from unauthorized access and malicious attacks. By filtering traffic according to established policies, firewalls enforce security boundaries and prevent unwanted communication.

Question 5

What are access control lists (ACLs)?

Accepted Answer

Traffic control rules

Answer

Access Control Lists (ACLs) are sets of rules used to filter network traffic and control access to network resources. They specify which users or system processes are granted access to objects, as well as what operations are allowed on those objects. ACLs are crucial for enforcing security policies on routers, switches, and firewalls, determining whether packets should be forwarded or dropped based on criteria like source/destination IP addresses or port numbers.
