What techniques detect DNS spoofing attempts inside corporate networks?

Asked on Nov 11, 2025

Answer

Detecting DNS spoofing attempts within corporate networks involves monitoring DNS traffic for anomalies and implementing security measures to safeguard DNS integrity. Techniques include using DNSSEC, monitoring DNS query patterns, and employing intrusion detection systems (IDS) to identify suspicious activities.

Example Concept: DNS spoofing detection involves analyzing DNS traffic for irregularities such as unexpected IP addresses in responses, unusually high volumes of DNS queries, and discrepancies between DNS query and response times. Implementing DNSSEC (Domain Name System Security Extensions) helps ensure data integrity and authenticity by digitally signing DNS data, making it more difficult for attackers to alter DNS responses without detection.

Additional Comment:

Regularly update and patch DNS servers to mitigate vulnerabilities.
Use DNS logging and analysis tools to track and alert on suspicious DNS activities.
Implement network segmentation to limit the impact of potential DNS spoofing attacks.
Consider deploying DNS filtering solutions to block malicious domains.
