Top ERP Security Risks You're Probably Ignoring (And Best Practices to Fix Them)

Your ERP system knows almost everything about your business: finances, employees, customers, inventory, procurement, and operations. It's the central hub that keeps your organization running.

That's exactly why it's a target for cybercriminals.

According to a report, thousands of ERP vulnerabilities are discovered every year, yet many organizations remain unaware of their exposure. The real concern isn't just the number. It's that many of these risks come from decisions businesses make themselves: weak passwords, delayed updates, over-permissioned accounts.

Still not convinced? In 2022, security researchers documented that a critical SAP vulnerability (ICMAD, CVSS 10.0) was patched in February - yet it was exploited so persistently throughout the year that CISA added it to its list of most frequently exploited vulnerabilities. The reality is attackers routinely weaponize patches within 72 hours, but most businesses take over 90 days to install them. That gap is where breaches happen.

The lesson is clear: ERP security is more than just an IT issue, it's a business risk.

This blog covers the most overlooked ERP security risks, why they happen, and the best ERP security practices to protect your business.

Why ERP Security Often Becomes an Afterthought

When a business implements an ERP system, the focus is almost always on getting it up and running, configuring modules, migrating data, integrating business processes, and training employees. Security gets pushed to the back.

There's also a common misconception that "the ERP vendor handles security." And while ERP vendors do their part, they can only secure the software itself. 

Everything around it: how users access it, how it connects to other tools, how data is stored, that's your responsibility.

ERP data security is a shared job. When businesses fail to recognize that, security gaps appear quickly.

The ERP Security Risks You're Probably Ignoring

1. Weak or Shared Login Credentials

This may sound basic, but it's still one of the most common ways attackers gain access to ERP systems.

• Default passwords that were never changed. 
• Team members sharing a single login because "it's easier." 
• No multi-factor authentication.

If an attacker obtains valid credentials through phishing, credential stuffing, or data leaks, they can gain immediate access to critical business data.

How to Fix It

• Enforce unique login credentials for every user.
• Implement strong password policies.
• Enable multi-factor authentication (MFA) for all users, especially administrators.
• Immediately revoke access when employees leave the company.

These simple measures can prevent a significant percentage of credential-based attacks.

2. Users Having More Access Than They Need

Many ERP environments are configured quickly during ERP implementation and rarely reviewed afterward. 

The result?

• Sales staff accessing HR information
• Interns receiving elevated permissions
• Former managers retaining access after role changes
• Employees viewing data unrelated to their responsibilities

Over-permissioned accounts increase both security and compliance risks.

How to Fix It

Implement Role-Based Access Control (RBAC).

Each user should only have access to the data and functionality required to perform their job.

Additionally:

• Review permissions regularly.
• Reassess access whenever an employee changes roles.
• Conduct formal access reviews at least annually.

3. Delayed Updates and Security Patches

ERP upgrades can be inconvenient.

They require testing, validation, and occasional downtime. As a result, many organizations postpone updates for months, or even years.

Unfortunately, attackers actively search for organizations running outdated ERP versions because known vulnerabilities are often publicly documented.

This is one of the most preventable ERP security risks, yet it remains widespread.

How to Fix It

• Establish a regular patch management schedule.
• Test updates in a staging environment before deployment.
• Prioritize security patches over feature updates.
• Work with your ERP consultant or implementation partner to streamline upgrades.

The cost of applying patches is almost always lower than the cost of recovering from a security breach.

4. Insecure Third-Party Integrations

Modern ERP systems rarely operate in isolation.

They're connected to:

• CRM platforms
• Payment gateways
• E-commerce systems
• Logistics software
• Marketing tools
• Business intelligence platforms

Every integration introduces another potential attack surface.

A vulnerable third-party application can become an entry point into your ERP environment.

How to Fix It

• Audit all connected applications regularly.
• Verify that integrations use secure APIs and authentication methods.
• Review vendor security practices.
• Remove integrations that are no longer actively used.
• Apply the principle of least privilege to integration accounts.

5. Poor ERP Data Security Practices

Many businesses assume their data is automatically protected.

In reality, sensitive information may be exposed if proper safeguards aren't configured.

This includes:

• Financial records
• Customer information
• Employee data
• Payroll information
• Business-critical operational data

Without encryption, intercepted data can potentially be read and misused.

Another overlooked issue is the lack of data masking, which allows users to view sensitive information they don't actually need.

How to Fix It

• Encrypt data both at rest and in transit.
• Enable data masking for sensitive fields.
• Restrict visibility of confidential information.
• Regularly review data access policies.

Users should only see the information necessary to perform their responsibilities.

6. Cloud ERP Misconfiguration

Cloud ERP solutions offer flexibility, scalability, and reduced infrastructure management. However, cloud security isn't automatic.

Common cloud ERP security issues include:

• Publicly accessible storage
• Incorrect permission settings
• Unnecessary open network ports
• Misconfigured access controls

Many organizations misunderstand the shared responsibility model.

While cloud providers secure the underlying infrastructure, customers remain responsible for configuration, user access, and data protection.

How to Fix It

• Conduct regular cloud configuration audits.
• Review storage permissions and network settings.
• Validate user access policies.
• Monitor publicly exposed resources.
• Ensure your ERP implementation partner follows security best practices, not just functional requirements.

A single misconfiguration can unintentionally expose sensitive business data to the internet.

7. Lack of Audit Trails and Activity Monitoring

If someone downloaded thousands of customer records tonight, would you know?

For many organizations, the answer is no.

Without proper monitoring and audit logging, suspicious activity can remain undetected for weeks or even months.

How to Fix It

• Enable audit logging across all ERP modules.
• Configure alerts for unusual activity such as large data exports, logins at odd hours, repeated failed login attempts. 
• Review logs regularly.

You don't need a dedicated security operations team to gain visibility. Most modern ERP platforms already include monitoring capabilities that simply aren't being used.

8. Over-Privileged Admin and Service Accounts

One of the most overlooked ERP security risks involves accounts with elevated privileges.

These include:

• ERP administrators
• IT administrators
• Consultants
• Service accounts used for integrations and backups

Because these accounts often have unrestricted access, a compromise can lead to complete control of the ERP environment.

How to Fix It

• Create tiered administrative roles.
• Separate infrastructure administration from ERP administration.
• Rotate service account credentials regularly.
• Require approval workflows for sensitive administrative actions.
• Monitor privileged account activity closely.

Privileged accounts should receive the highest level of security oversight, not the least.

ERP Security Best Practices: A Quick Checklist

Here's a consolidated list of ERP security best practices to keep your system protected:

• Enable MFA for all users
• Implement role-based access control (RBAC)
• Review user permissions regularly
• Keep ERP systems fully patched and updated
• Audit third-party integrations
• Remove unused applications and connections
• Encrypt data at rest and in transit
• Enable data masking where appropriate
• Conduct cloud configuration reviews
• Enable audit logging and activity monitoring
• Implement tiered administrative privileges
• Rotate service account credentials
• Perform ERP security audits annually
• Establish clear process for deactivating accounts when employees leave
• Train employees on phishing awareness and credential security

Remember: most successful cyberattacks begin with human error, not technical vulnerabilities.

Where to Start First with ERP Security

If you're unsure where to begin, prioritize these high-impact actions:

• No MFA Enabled? Turn it on immediately, especially for all admin accounts.
• Still Using Default Passwords? Change them, this takes a few minutes.
• No Audit Logging? Enable logs and create at least one alert for repeated failed login attempts.
• Former Employee Accounts Still Active? Deactivate them immediately.
• No Patch Management Process? Schedule monthly security review sessions.
• No Access Review Process? Export current user permissions and identify unnecessary access.
• No Integration Audit? Create a list of all integrations and remove any you don't recognize or use.

These actions provide immediate risk reduction without requiring major investment.

ERP Security Controls: Moving from Reactive to Proactive

Many organizations only think about ERP security after an incident occurs.

A stronger approach is to build security into everyday ERP operations.

This typically involves three categories of controls:

Preventive Controls

Designed to stop incidents before they occur:

• MFA
• RBAC
• Encryption
• Secure configuration management
• Password policies

Detective Controls

Designed to identify suspicious activity quickly:

• Audit logs
• Security monitoring
• User access reviews
• Automated alerts

Corrective Controls

Designed to minimize damage and support recovery:

• Incident response procedures
• Backup and recovery plans
• Escalation workflows
• Disaster recovery testing

These controls also help organizations meet compliance requirements such as GDPR, ISO 27001, SOC 2, and industry-specific regulations.

A Note on Cloud ERP Security

Cloud ERP offers substantial advantages:

• Lower infrastructure costs
• Improved scalability
• Faster deployment
• Remote accessibility

However, choosing a cloud ERP solution doesn't eliminate security responsibilities.

When evaluating a cloud ERP provider, ask:

• Where is my data stored?
• Who can access it?
• What exactly does your shared responsibility model cover?
• How are patches and updates managed?
• Which security and compliance certifications do you maintain?
• What monitoring and incident response capabilities are available?

If these questions cannot be answered clearly, consider it a warning sign.

Strong cloud ERP security requires both a trustworthy provider and a properly configured deployment.

What a Real ERP Security Audit Looks Like (And Why Most Don't Do It)

A proper internal audit isn't just running a vulnerability scan. It should answer:

• Identity: Who currently has access, and do they still need it?
• Activity: How are users interacting with the system? Are there unusual access patterns or large data exports (10,000+ rows at 2 AM)?
• Security Gaps: Where are security controls assumed rather than enforced?
• Configuration Drift: What changes have occurred over the past 90 days, and were they properly approved?

Many organizations avoid audits because they seem time-consuming.

In reality, spending a few hours reviewing your ERP environment twice a year is significantly less costly than responding to a major security incident.
