How to Build an Access Control Strategy from Scratch

In today’s security-driven world, protecting your physical space is just as important as securing your digital data. Whether you manage a small business, a corporate office, or an industrial site, having a well-planned access control strategy ensures that only the right people can access the right places at the right time.

At XTEN-AV, we help security professionals and businesses design and deploy effective AV and security systems, including intelligent access control plans. If you are starting from square one, this blog will guide you step-by-step on how to build an effective Access Control System strategy from the ground up.

Step 1: Define Your Security Goals

Before diving into technology or hardware, clearly define why you need an access control system. Consider questions like:

What are you trying to protect?
Who needs access and to which areas?
What risks or threats are you concerned about?

Your goals might include preventing unauthorized entry, protecting sensitive information, controlling visitor access, or ensuring employee safety. Clear goals provide a foundation for every decision that follows.

Step 2: Assess Your Facility and Entry Points

Every facility is unique. Walk through your building and identify all entry and exit points including:

Main entrances
Emergency exits
Stairwells and elevators
Server rooms or restricted zones
Parking areas and delivery docks

Map out these areas and decide which ones need controlled access. Knowing where access needs to be managed helps you determine where to place readers, locks, and cameras.

Step 3: Categorize User Groups

Next, list the different types of people who need access. Common user groups include:

Employees
Visitors
Vendors or contractors
Maintenance staff
Executives or administrators

Each group will have different access needs. For example, employees may access certain office areas during business hours, while cleaning crews may need evening access to shared spaces.

Step 4: Choose the Right Authentication Methods

Your access control system should support the right type of credentials for your environment. Choose one or more of the following based on your goals:

Keycards or fobs: Widely used and easy to manage
PIN codes: Low cost but less secure if shared
Biometric access: High security using fingerprints or facial recognition
Mobile credentials: Convenient and scalable using smartphones

For high-security areas, consider multi-factor authentication that combines two or more methods.

Step 5: Set Access Permissions and Schedules

Once you have defined user groups and entry points, create access rules. This includes:

Which doors each group can access
What times access is allowed
Temporary or one-time access for visitors or contractors

For example, your IT team may have 24-hour access to the server room, while general staff can only enter the building from 8 am to 6 pm on weekdays.

Step 6: Plan Hardware and Infrastructure

Now that you have your strategy outlined, it is time to choose the physical components of your system. You will need:

Door controllers: To manage and record access decisions
Electronic locks: Such as magnetic locks or electric strikes
Credential readers: Card, biometric, or mobile readers
Access management software: Cloud or on-premise

Make sure your infrastructure supports future expansion and integration with other systems like CCTV, alarms, or building automation.

Step 7: Establish a Monitoring and Alert System

A strong access control strategy does more than just grant or deny entry. It also logs activity and alerts your team to unusual events.

Use your software to:

Track who accessed what area and when
Send real-time alerts for unauthorized attempts or door propping
Generate reports for audits or investigations

Integration with video surveillance adds another layer of verification and security.

Step 8: Implement Role-Based Access Control

To simplify management, assign access based on job roles rather than individuals. This approach, known as role-based access control (RBAC), makes it easier to grant, change, or revoke permissions as people change roles.

When an employee joins or leaves a department, their access can be updated with a few clicks—no need to manually adjust permissions door by door.

Step 9: Train Users and Create Policies

Even the best access control system can fail if users do not follow best practices. Offer training to employees on:

How to use access credentials properly
The importance of not sharing cards or codes
What to do if a card is lost or stolen
How to recognize and report suspicious activity

Also, create and distribute an official access control policy that outlines rules and consequences for misuse.

Step 10: Test the System Before Going Live

Before launching your new access control strategy, conduct thorough testing. Test various scenarios such as:

Approved access during regular hours
Denied access outside of allowed times
Emergency lockdown or fire alarm overrides
Guest access and temporary credentials

This ensures the system behaves as expected and gives users confidence in its reliability.

Step 11: Plan for Maintenance and Updates

A good access control strategy is not “set it and forget it.” Schedule regular:

Software updates and firmware checks
Access permission reviews
Battery checks on wireless devices
Audits of entry logs and event history

Also, be ready to scale. As your business grows or changes locations, your access control system should be flexible enough to adapt.
