The ‘Just This Once’ Problem: How Small Exceptions Create Big Risks
Article summary: A single “just this once” exception to a security policy rarely causes harm on its own, which is exactly why it keeps happening. Over time, these small workarounds quietly reshape what counts as normal in a business, until real security policy exceptions have piled up into a wide-open door. Recognizing the pattern early, and building simple habits to catch it, keeps one favor from turning into a costly incident.
It usually starts with a reasonable-sounding request. Someone on the team needs access to a shared drive for a project that ends next week. IT grants it “just for now,” and everyone moves on.
Six months later, nobody remembers why that access exists, and nobody has checked whether it should. That single favor is how access control policies quietly stop meaning what they say, one security policy exception at a time.
How One Exception Becomes the New Normal
Sociologist Diane Vaughan studied this pattern long before it had anything to do with computers. She coined the term normalization of deviance after investigating the 1986 Space Shuttle Challenger disaster.
Engineers had noticed damage to the shuttle’s O-rings on earlier flights. Nothing catastrophic happened, so the damage was reclassified as an acceptable risk instead of a warning sign.
NASA’s own retrospective on the disaster describes how each successful flight made the next bit of damage easier to wave off, until the pattern caught up with them.
Business IT works the same way, just with lower stakes most of the time. A shared login “just until the new hire gets set up.” A firewall rule opened “temporarily” for a vendor. None of these single moments feel like a crisis. That’s the trap.
What Small Exceptions Actually Cost
62% of data breaches involve some form of human element, from stolen credentials to simple error.
According to Verizon’s 2026 Data Breach Investigations Report, that human element rarely looks dramatic at the moment. It looks like a password shared over chat or an account nobody remembered to remove.
Employees know this tension exists. CyberArk’s research on workplace security behavior found that 65% of employees regularly bypass security policies to make their day easier, often through habits like forwarding work email to a personal account.
The financial picture backs this up. DTEX’s 2026 Cost of Insider Risks report, conducted by the Ponemon Institute, found that negligent behavior, not malicious insiders, now drives the highest share of insider-related losses.
It averages $10.3 million per year across the organisations studied. Nobody in that data set set out to cause a breach. They just made an exception that stuck around too long.
Where Exceptions Tend to Creep In
Small businesses run into the same handful of patterns over and over.
Shared logins for convenience
One login gets passed around a small team “to save time” setting up new accounts. Nobody can tell who actually did what once something goes wrong, and these accounts tend to outlive their purpose long after the original reason for sharing them is forgotten.
Temporary access that never expires
Contractors, seasonal staff, and departed employees often keep access for months after they stop needing it, simply because removing it wasn’t anyone’s clear job.
Admin rights handed out by default
Giving every laptop admin rights avoids a support call today. It also means one bad email attachment can install software across the whole machine, not just one folder.
Bypassed updates on a “critical” system
The system that’s too important to reboot is usually the one that goes longest without a patch, because nobody wants to be the one who causes downtime.
Building a Culture That Catches Exceptions Early
The fix isn’t a stricter rulebook. It’s a habit of checking exceptions before they quietly become policy.
CISA’s Cyber Essentials guidance puts it plainly: grant access based on need-to-know and least privilege, and build a process for reviewing that access when someone’s role changes. That single habit closes off most of the patterns above before they have time to calcify.
A few practices make this manageable for a small team:
- Set a default expiration date on any “temporary” access, so it has to be renewed on purpose instead of forgotten.
- Keep a short list of every exception granted in the last 90 days and review it monthly.
- Separate admin accounts from everyday accounts, even for the owner.
- Treat every exception as a decision that needs a reason attached to it, not just a favor.
None of this requires new software. It requires deciding that today’s exception stays an exception, not tomorrow’s default.
Ready to Find Your Own Blind Spots?
Every business has a few of these lingering exceptions somewhere in its systems. Most owners only find out when something goes wrong.
A short access review can surface shared logins, forgotten admin rights, and permissions that outlived their purpose, all before they turn into a real security policy exception with real consequences.

Article FAQs
What is a security policy exception?
A security policy exception is any deviation from a standard security rule, like sharing a login, granting temporary access, or skipping a required update, made for convenience rather than through a formal, reviewed process.
Why do small security exceptions become a problem?
Each individual exception feels harmless because nothing bad happens right away. Over time, though, unreviewed exceptions accumulate, and the business ends up with far more access and risk than anyone intended.
How often should a business review access permissions?
A monthly review of recent exceptions and a quarterly review of all standing access works well for most small businesses. Least privilege guidance from CISA recommends granting access based on need and reviewing it whenever a role changes.
