Top 5 Cybersecurity Risks in ERP Systems and How to Prevent Them

Modern businesses are built on Enterprise Resource Planning (ERP) systems. From finance to supply chain, they run everything in one place. Many of them can even connect to cloud systems, mobile apps, and IoT devices. But where they are most powerful, they are also most vulnerable.

Cybercriminals know that ERP systems are treasure troves of data. So if an attack happens, it can lead to significant data theft. Not only that, it can also delay payroll, damage production lines, and stop operations.

Protecting ERP systems, then, is not only about mitigating data loss. Ultimately, it's about ensuring business continuity.

Need help with that? In this article, we'll discuss five of the most serious risks facing ERP systems. We will also discuss why deciding to hire ERP developers can help your organization successfully prevent these issues.

Why ERP Risks Are an Urgent Matter

ERP systems can be likened to the central nervous system of a business. They control the whole operation. That's why a breach should be treated as an emergency: one security event can ripple across the whole organization.

The Damage to SMBs

SAP says that 43% of data breaches involve small and medium-sized businesses. And when they hit, SMBs won't have the resources of larger enterprises that could help cushion the impact.

Also, SMBs may not have the in-house expertise necessary to address these attacks.

To mitigate these consequences or prevent them altogether, expert ERP developers from tested companies like DevTeam Space say the best course of action is to consult a professional ERP development team.

Heightened Connectivity, Heightened Risks

According to IoT Analytics, the number of connected IoT devices in 2025 will total nearly 30B. Many of these devices feed directly into ERP systems. So that means that each connected device is a potential entry point.

If a breach occurs, the impact can extend far beyond the core system and continue to expand.

The Reality of Ransomware

Industry data from N2W says that 4,000 ransomware attacks happen every day. And with every incident, recovery costs per incident amount to nearly 2.8 million dollars.

So when an ERP system gets compromised, it's not just an inconvenience. It's a very expensive event that can paralyze your operations and seriously hurt your reputation.

5 Most Common Types of Cybersecurity Risk for ERP Systems + Ways to Prevent Them

ERP systems are vulnerable to a wide range of risks, which come from both human practices and technical flaws.

Here are five of the most common examples, along with practical steps that you can take to prevent them.

1. Unknown Vulnerabilities and Outdated Software

ERP systems are built to last long, running on a combination of bolt-on modules, custom code, and third-party add-ons. They're scalable and cost-effective, but also unnecessarily prone to security vulnerabilities through:

• Legacy systems: Many ERP systems still run on outdated versions, so it's difficult to spot issues and effectively mitigate them. Older code and undocumented modifications can create multiple opportunities for exploitation.

• Delayed patching: Making ERP updates can be disruptive. So what do some companies do? They delay applying patches. But instead of protecting your business, this can open up more gaps for risks that might just halt your operations.*/

• Cloud misconfigurations: Mistakes like weak identity policies can also potentially expose sensitive data. And according to IBM, misconfigured cloud services account for nearly 25% of cloud security incidents.

Ways to Prevent

When you hire ERP developers, you can head off these issues by:

• Establishing regular patch cycles and conducting testing in sandbox environments before deployment

• Enabling continuous vulnerability scanning for core ERP and custom modules

• Using cloud security posture management (CPSM) tools to instantly detect and address misconfigurations

2. Weak Authentication

Authentication is one of the first vulnerabilities that attackers exploit. And unfortunately, they don't even need sophisticated tools to succeed. ERP risks related to authentication often come from:

• Credential theft: Verizon says that around 88% of breaches come from compromised credentials. Common attacks include phishing emails, credential stuffing, and brute force.

• Shared accounts: Sharing ERP logins may save time and costs, but it weakens security. There's also no way to track who did what. This further hurts transparency and prevention efforts.

• Weak password hygiene: Some employees reuse the same passwords across various applications. And once one platform is breached, the risk rises for the other platforms.

Ways to Prevent

To prevent your ERP system from getting compromised because of weak authentication, consider:

• Requiring multi-factor authentication (MFA) across all your ERP accounts

• Enforcing unique IDs for users, depending on their roles

• Adopting adaptive authentication to block logins from unrecognized devices, IPs, or geographical locations

• Regularly training employees on password hygiene and security awareness

3. Web Application Vulnerabilities

Many ERP systems have become web-enabled, which has also upped their risks through:

• API weaknesses: Modern ERPs depend heavily on APIs for third-party integration. But poorly secured APIs can create backdoors for attackers.

• Classic hacking strategies: SQL injections or cross-site scripting still work in many instances. Especially in environments that don't have secure coding practices.

Ways to Prevent

To manage these risks, your business should implement:

• Enforcing secure coding practices for ERP customizations

• Monitoring API activity through secure gateways to catch unusual requests or data flows

• Deploying a Web Application Firewall (WAF) to block suspicious traffic in real-time

• Conducting regular penetration testing to identify and fix vulnerabilities

4. Improper Configuration and Excessive Access

ERP systems are highly customizable. And while this is a big benefit, it can also be a big risk. Improperly managed roles, permissions, and configurations can create opportunities for attackers, especially through:

• Failures in duty segregation: In some organizations, some employees have overlapping responsibilities. For example, one supervisor may be allowed to both create and approve vendor payments. This can open up several avenues for exploitation.

• Configuration Blind Spots: Has your ERP system evolved since it was first implemented? Then there may be security settings that haven't been updated or documented. These blind spots can be easy targets for attackers.

Ways to Prevent

To navigate this issue, you and your ERP development company should look at:

• Enforcing the principle of least privilege, so employees have access only to the right resources

• Conducting quarterly access reviews to delete or update permissions

• Enforcing segregation of duties so users don't have conflicting responsibilities

• Using automated access management tools to safeguard access to privileges

5. Unauthorized Tools and Integrations

ERP systems don't work in isolation. They connect with CRMs, e-commerce platforms, IoT devices, and more. This is what makes them efficient and powerful. But it also increases their risks from:

• Shadow IT issues: Some employees might use unapproved apps to speed up or ease their tasks. And some of these tools may lack enterprise-grade security.

• Supply chain exposure: Partner vendors that don't have robust security protocols are also a source of vulnerability. And a single weak link can compromise your whole system.

Ways to Prevent

To avoid these problems from appearing in the first place, cultivate these practices at work:

• Maintaining a centralized inventory of ERP integrations for visibility

• Conducting risk assessments of vendors before onboarding

• Opting for API gateways with strong authentication and encryption

• Establishing clear policies against unauthorized integrations

Proactive Protection of Your ERP Systems

While these risks can be daunting, they can all be mitigated by proactive strategies. You can also revamp your disaster recovery plans to make sure they are relevant and timely to your needs.

However, to build true resilience, you need a holistic view of your whole infrastructure. That's why it pays to hire ERP developers who understand both system functionality and security best practices.

With an ERP software development company, you don't just prevent risks; you equip your organization with an ERP system that optimizes business continuity and success.
