Which of the following is a method to prevent unauthorized access to a system?
A. Disabling firewalls
B. Sharing login credentials
C. Multi-factor authentication
D. Using default passwords
Answer: Option C
Solution (By JKSSB Mock Tests)
Multi-factor authentication requires users to provide multiple forms of verification, significantly reducing the risk of unauthorized access even if one factor is compromised.
Explanation:
A security token, such as a hardware token or a mobile app, generates a one-time password (OTP) that is used as a second factor in authentication, enhancing security.
Explanation:
A network firewall enforces security policies by controlling traffic based on rules, preventing unauthorized access and protecting the network.
Which type of network security exploit uses a fake wireless router with the exact same SSID label as a corporate office network to trick workers into connecting so the attacker can log their data traffic?
Explanation:
