TL;DR: Man-in-the-middle risk is reduced by stronger authentication, encryption, monitoring, and access controls, according to StrongDM’s guide, but the underlying issue is that attackers exploit trust in the communication path as much as the credential itself. That makes interception resistance a governance problem for human, workload, and privileged access, not just a network-hardening checklist.
Editorial analysis by NHI Mgmt Group, based on content published by StrongDM: “10 Ways to Prevent Man-in-the-Middle (MITM) Attacks”.
Key questions
Q: What breaks when access controls are the only line of defence against MITM attacks?
A: Access controls fail when an attacker intercepts the session before authorization becomes meaningful.
Q: Why do MITM attacks remain dangerous even when encryption is in place?
A: Encryption protects content, but it does not automatically prove the endpoint, the session route, or the legitimacy of the access attempt.
Q: How do security teams know whether privileged session controls are actually working?
A: They should test whether high-risk admin sessions are phishing-resistant, bound to known devices, and short-lived enough to prevent reuse after compromise.
Practitioner guidance
- Strengthen endpoint verification Require users and admins to verify certificates, HTTPS, and known destinations before submitting credentials or approving remote access.
- Reduce credential exposure in access workflows Remove direct username and password entry where possible and centralize access so credentials are not repeatedly presented on untrusted paths.
- Enforce MFA across sensitive access paths Apply multi-factor authentication to database, server, and remote administrative access so a stolen password is not enough to complete a session.
Bottom line: MITM defence cannot rely on access controls alone because interception targets the communication path as much as the credential.

Access-centric security leaves a trust gap when the path is the target: MITM attacks show that authenticating the user is not the same as authenticating the communication path. A control stack built around credentials, roles, and permissions can still fail if the session is intercepted before those controls are exercised. The practitioner implication is that identity security must account for path trust, not only identity proof.
A few things that frame the scale:
- 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: Should organisations prioritise access governance or transport security first for MITM risk?
A: They should treat them as complementary controls, not alternatives. Transport security reduces interception opportunities, while access governance limits what an attacker can do if a session is compromised. The better sequencing depends on the environment, but neither control should be considered sufficient on its own.
