We will preface this post by noting – WE ARE NOT AN IT COMPANY AND DO NOT PROVIDE IT OR POS RELATED SERVICES. That said, we do work with IT companies and as an addition to our continued focus on security, we have pout together the following article to help point clients in the right direction when it comes to choosing and working with their POS systems.
——————————————————-
1. Reduces Attack Surface
A device used solely for POS transactions isn’t exposed to other high-risk activities like browsing the internet, checking emails, or installing unrelated software—all common entry points for malware, phishing, and ransomware.
Benefit:
Less risk of infection or compromise from external sources.
2. Prevents Cross-Contamination
If employees or owners use the same device for personal or other business tasks, there’s a higher risk of inadvertently downloading malicious software or storing sensitive data in insecure ways.
Benefit:
Keeps sensitive POS functions isolated from non-secure environments.
3. Enhances Performance
POS systems often need to operate quickly and reliably. A cluttered, multi-use system may suffer from slowdowns or software conflicts.
Benefit:
Improved speed and reduced risk of software crashes during transactions.
4. Supports Compliance Requirements
Payment Card Industry Data Security Standards (PCI DSS) emphasize minimizing risks to payment environments. A dedicated device helps demonstrate segmentation and control over the POS environment.
Benefit:
Easier compliance with PCI DSS and other security audits.
5. Easier Maintenance and Monitoring
A dedicated POS system allows IT teams to more easily monitor logs, update POS software, and manage patches without affecting other business operations.
Benefit:
Streamlined security management and troubleshooting.
Recommended Setup for a Dedicated POS Computer
- No Web Browsing or Email Clients Installed (no web browsing if your POS is internet based)
- Auto-login disabled and password protected
- POS software and operating system kept up-to-date
- Firewall and antivirus configured specifically for POS usage
- Use of hardware security (e.g., locked enclosures, restricted USB ports)
- Regular backups configured to a secure location
Bottom Line
Using a dedicated computer or terminal for your internet-based POS system is a smart investment in security, stability, and compliance. It’s a relatively low-cost measure that significantly reduces the risk of cyber incidents and operational disruptions.
