When people think about security threats, they often picture strangers. An unknown person attempting to break in or someone suspicious lurking nearby. While those risks do exist, they are not always the most common or the most dangerous.

In many cases, the greater risk comes from people who are already familiar. These can include former employees, contractors, service providers, or even acquaintances who have some level of access or knowledge about a property.

Understanding insider risk is essential for both homeowners and businesses. It is not about distrust. It is about awareness and control.

Why Familiar Access Creates Risk

People who are familiar with a property often have advantages that outsiders do not. They may know entry points, routines, security system placement, or times when a property is unoccupied.

In a business setting, this can include employees who have access to restricted areas or sensitive information. In a residential setting, it could be someone who has been given a spare key, alarm code, or temporary access.

According to the Cybersecurity and Infrastructure Security Agency (CISA), insider threats can come from current or former employees, contractors, or business partners who have authorized access and misuse it.

Common Examples of Insider Risk

Insider threats are not always malicious from the start. Sometimes they develop over time or result from poor access management.

Examples include:

• Former employees who still have active access credentials
• Contractors or vendors with unrestricted entry beyond their job scope
• Shared alarm codes that are never updated
• Lost or unreturned keys or access cards
• Employees accessing areas or data outside their role

In residential environments, similar risks can appear when access is given without clear limits or follow-up like to a babysitter, housekeeper or contractor.

The Hidden Risk of Convenience

Convenience is one of the biggest contributors to insider risk. It is easy to reuse the same alarm code, avoid updating access permissions, or leave systems unchanged after someone no longer needs access.

Over time, these small decisions create vulnerabilities.

For example:

• A former employee who still has a keycard
• A neighbor who knows your alarm code
• A shared login that multiple people use

These situations may seem harmless until they are not.

How to Reduce Insider Risk

Managing insider risk is about maintaining control over who has access and when.

Limit and Track Access
Only give access to individuals who need it, and ensure it is limited to specific areas or systems.

Update Credentials Regularly
Change alarm codes, passwords, and access permissions whenever roles change or access is no longer required.

Use Access Control Systems
Modern systems allow you to assign, monitor, and revoke access in real time. This reduces reliance on physical keys and shared codes.

Businesses looking to improve control over who enters their facility can benefit from access control systems that provide visibility and accountability.

Monitor Activity
Video surveillance and system logs help track who is entering and exiting your property. This adds a layer of accountability.

Establish Clear Policies
Whether at home or in a business, set expectations around access. Who is allowed in, when, and under what conditions should be clearly defined.

Awareness Without Overreaction

It is important to approach insider risk with balance. Most people with access to your home or business are trustworthy. However, security should not rely solely on trust.

By putting systems and processes in place, you reduce the chance of misuse while maintaining a safe and professional environment.

Protect What Matters Most

Security is not just about keeping strangers out. It is about controlling access at every level and ensuring that only the right people have the right access at the right time.
