8 ERP security best practices for modern ERP environments

Enterprise resource planning (ERP) systems are treasure troves of sensitive business data—which makes securing them a top priority in today’s threat landscape. In a recent TechTarget article, Kevin Beaver of Principle Logic outlines eight practical security best practices for modern ERP environments. With supply chain attacks on the rise and remote access now standard, he argues that ERP security can’t be treated as an afterthought. One key theme: whether your ERP is on-premises or in the cloud, security is still your responsibility. Assuming a SaaS vendor has everything covered is a risky misconception. Even in cloud environments, organizations must stay actively involved in monitoring, access control, and risk management.

Beaver’s first recommendations are foundational: enable multifactor authentication (preferably app- or token-based, not SMS) and enforce strong password policies. Just as critical is staying on top of software updates. Unpatched systems—especially those missing years-old fixes—are easy targets for attackers. Beyond technical controls, he emphasizes people and process. Educate users and make them partners in security. Build and regularly refine a documented incident response plan. Conduct vulnerability scans, penetration tests, and threat modeling to uncover weak spots. For cloud ERP, review vendor SOC 2 reports at a minimum. Ongoing monitoring is also essential. Whether handled in-house or outsourced, organizations need visibility into logs, alerts, and suspicious activity.

Beaver urges companies to take a structured approach: know what assets exist, understand the risks, and act decisively to mitigate them. His bottom line is simple: ERP security doesn’t fix itself. The best time to strengthen it is before a breach forces your hand.
