Mutual authentication can prevent which type of attack? A) Wireless poisoningB) Wireless IP spoofingC) Wireless sniffingD) Man-in-the-middle Correct Answer is D) Man-in-the-middle Mutual authentication can prevent which type of attack? Explanation: Mutual authentication is a security mechanism that requires both parties in a communication to authenticate each other's identities. It enhances security by preventing unauthorized access, as each party must prove their identity before any data is exchanged. There are several types of attacks that mutual authentication can prevent. Preventing Man-in-the-Middle Attacks: One of the main types of attacks that mutual authentication can prevent is man-in-the-middle (MITM) attacks. MITM attacks…

Which methods can be used to implement multifactor authentication? A) VPNs and VLANsB) IDS and IPSC) Tokens and hashesD) Passwords and fingerprints Correct Answer is D) Passwords and fingerprints Which methods can be used to implement multifactor authentication? Explanation: Multifactor authentication (MFA) is a security mechanism that requires users to provide multiple forms of identification to access a system or resource. It enhances security by adding an extra layer of protection against unauthorized access, as attackers would need to bypass more than one form of authentication to gain access to sensitive information or resources. There are several methods that can…
