Company XYZ is running SNMPv1 in their network and understands that it has some flaws.

SNMPv1 and SNMPv2c use plaintext community strings and lack built-in encryption or authentication, making them vulnerable to various attacks, including spoofing and message tampering. SNMPv3 addresses these weaknesses by introducing:

Authentication (to prevent impersonation or "masquerade")

Encryption (privacy)

Message integrity

“Masquerade threats” involve an attacker pretending to be a trusted source, which SNMPv3 can prevent via cryptographic authentication mechanisms.

Although SNMPv3 does provide improved security features like integrity and privacy, it is not specifically designed to mitigate volumetric attacks like DDoS or dictionary brute-force. SNMPv3 does not inherently stop man-in-the-middle attacks unless secure key exchanges and trusted paths are fully enforced, which may require additional protocols.
