Cracks in the System

25 November 2025

Cybersecurity threats don’t always kick the door down—sometimes, they slip in through the cracks. This month, we’re spotlighting three subtle but serious security risks that could be undermining your defences right now.

Cracks in the System

The Dangers of Misconfigured MFA

MFA is essential, but if poorly set up—like push-only prompts—it can be bypassed. Misconfigurations leave you exposed to attacks like MFA fatigue.

Why It’s a Risk:

Push-based MFA can be exploited through "MFA fatigue" attacks.

Misconfigured settings may allow fallback to SMS, which is more vulnerable.

Legacy systems might bypass MFA altogether.

What You Can Do:

Use number matching or device-bound authentication.

Block legacy authentication protocols.

Regularly test and audit MFA enforcement across users and devices.

When Auto-Updates Backfire

Giving staff admin access "just in case" creates unnecessary risk. Stick to least privilege to limit damage if an account is compromised.

Why It’s a Risk:

A rushed update might interrupt business-critical applications.

Firmware or driver updates can trigger system crashes or hardware issues.

Settings can reset, disabling important security controls.

What You Can Do:

Stagger updates across devices and monitor impact.

Test major patches in a sandbox before full rollout.

Use update policies to retain control over deployment timing.

How Insider Threats Slip Through the Cracks

Security policies can quickly become outdated. Old password rules or lack of cloud guidance could be silently undermining your defences.

Why It’s a Risk:

Sharing passwords or sensitive data without approval.

Using unsanctioned tools or cloud apps.

Clicking phishing links or ignoring security policies.

What You Can Do:

Monitor user behaviour for anomalies.

Provide clear policies and regular training.

Limit access to sensitive systems on a need-to-know basis.

A National Push for Cyber Resilience

Last month, UK government ministers issued a joint letter to the CEOs and Chairs of major organisations, urging action against rising cyber threats. The letter emphasised that cyber security must be a board-level priority and outlined three immediate actions for businesses:

  • Use the Cyber Governance Code of Practice to guide decision-making and incident response planning.

  • Register for the NCSC’s Early Warning service to detect threats before they escalate.

  • Mandate Cyber Essentials across your supply chain as a minimum standard.

This reinforces Cyber Essentials not only as a technical benchmark, but as a key requirement for doing business responsibly in today’s digital economy. Read more about it here!
