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.
NHIMG editorial — based on content published by StrongDM: 10 Ways to Prevent Man-in-the-Middle (MITM) Attacks
By the numbers:
- 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures.
- 80% of identity breaches involved compromised non-human identities such as service accounts and API keys.
- When AWS credentials are exposed publicly, attackers attempt access within an average of 17 minutes.
Questions worth separating out
Q: How should security teams reduce man-in-the-middle risk in identity flows?
A: Start by hardening the trust boundary around the session, not just the password.
Q: Why do MFA and encryption still leave organisations exposed to MITM attacks?
A: MFA and encryption reduce risk, but they do not fully prevent live proxy attacks.
Q: What do security teams get wrong about protecting service accounts from interception?
A: They often focus on secret strength while ignoring where the secret is presented and how it is validated.
Practitioner guidance
- Shift from login assurance to session assurance Review where your controls stop at authentication and where they continue through the session lifecycle.
- Reduce credential value in transit Remove direct credential entry where possible, prefer passwordless or brokered access, and ensure exposed credentials cannot be reused broadly if a proxy attack succeeds.
- Tighten recovery and phishing paths Audit password reset, link-clicking, and browser-based authentication flows for proxy abuse.

StrongDM's full blog covers the operational detail this post intentionally leaves for the source:
- Step-by-step examples of how the platform centralises access across databases and servers when users connect from risky networks.
- The article’s specific guidance on passwordless authentication, VPN use, and certificate checking in day-to-day access flows.
- Detailed descriptions of audit logging and monitoring capabilities for tracing who accessed what, when, and how.
- How the vendor positions centralized access control alongside RBAC, ABAC, and PBAC for access enforcement.

MITM attack prevention: are access controls enough to stop interception?

MITM prevention is really a trust-boundary problem, not just a transport problem. The article frames interception as something encryption and VPNs can blunt, but the governance issue is that identity trust is being validated on a path the attacker can control. That matters across human IAM, privileged access, and workload access because each depends on a verifiable channel before the credential or token is accepted. Practitioners should treat the trust boundary, not the login form, as the real control surface.
A few things that frame the scale:
- 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures, according to the Ultimate Guide to NHIs.
- Only 5.7% of organisations have full visibility into their service accounts, which means interception risk is often paired with poor identity inventory discipline.
A question worth separating out:
Q: Who is accountable when a MITM attack captures credentials and session data?
A: Accountability sits across identity, network, and application owners because MITM exploitation spans all three layers. IAM teams own authentication strength and privilege limits, network teams own channel integrity and certificate validation, and application owners own session handling and logging. If any one layer is weak, the attacker can turn interception into valid access.
