The Importance For Preventing Cyber Attacks On ERP Software
Did you know an average cyberattack can cost a business more than $4 million? With everything going digital, this shocking number emphasizes the necessity for cyber security methods, most importantly in systems like ERP (Enterprise Resource Planning) platforms. More than 85% of organizations worldwide use Enterprise Resource Planning systems to run their operations.
However, with businesses now extensively using ERP systems, the risk of cyberattacks targeting ERP systems has also increased. This means that ERP systems security is no longer an option but must be a priority. This blog will discuss 15 strategies to improve security for ERP systems and mitigate cyberattacks against these systems. These broad approaches work well for every business, whether big or small.
Top 15 Strategies To Enhance Security For ERP Systems
The security of ERP systems needs to be a proactive, multi-layered approach. Some strategies organizations may pursue are:
1. Perform Regular Risk Assessments
Understanding potential vulnerabilities is the first step toward strengthening security for ERP systems. Periodic risk assessment allows you to realize possible weak points in your ERP system.
One such manufacturing company learned that outdated software patches in their ERP system left them vulnerable to ransomware attacks. Fixing this was critical for them to avoid a serious security leak.
Risk assessments should cover:
- User access controls
- Data storage methods
- Third-party integrations
- Network vulnerabilities

2. Implement Role-Based Access Control (RBAC)
Not all employees should have access to each module of your specific ERP system. Role-Based Access Control establishes that staff members only hold access to the information that is relevant to their role.
A marketing executive, for example, doesn’t need access to financial data, and a finance manager doesn’t need access to manufacturing workflows. This reduces the potential for misuse and accidental data leaks.
3. Implement Strong Password Policies
Weak passwords are all a hacker needs to enter a system. Stronger password enforcement leads to better ERP security.
Encourage employees to:
- Use passwords with a combination of different elements (letters, numbers, and symbols) and make them complex.
- Update passwords on a calendar plan.
- Avoid reusing old passwords.
- Using multi-factor authentication (MFA) would be best for an additional layer of security.
4. Keep The ERP System Updated And Patched Regularly
One of the easiest entry points for cybercriminals is old ERP software. A lot of times, vendors provide updates and patches for vulnerabilities. This update helps protect your ERP system from becoming on the radar of new threats.
A real-life example of this is the WannaCry ransomware attack, which targeted unpatched systems. The attack did not affect businesses that kept their systems updated.
5. Encrypt Sensitive Data
Data encryption means that even if a cybercriminal gets access to your ERP system, the data they find would be incomprehensible. It’s important to encrypt data stored in your system (data at rest) and data being transferred between systems (data in transit) for added security.
As an illustration, encryption of customer payment data in an e-commerce ERP system can prevent hackers from using sensitive information.
6. Monitor System Activity
Continuous monitoring of ERP system activity helps in detecting unusual behaviour early on. Use tools that generate alerts for different things, such as:
- Unauthorized login attempts
- Sudden data transfers
- Changes in system settings
Businesses can respond quickly to any potential threats, which lowers the impact of cyberattacks, with the help of real-time monitoring.
7. Regular Employee Training Programs
When it comes to cyber threats, employees are the first line of defence against them. Having regular training sessions can make them aware of the importance of security for ERP systems and the best practices to keep in mind. Include topics like:
- Identifying phishing emails
- Safely handling sensitive data
- Reporting suspicious activities
For example, an employee at a logistics company avoided a phishing attack by recognizing a fake email that mimicked the ERP vendor.
8. Implement Network Security Measures
A secure network is not a step in management; it forms the foundation of ERP system security. Invest in:
- Firewalls
- Intrusion detection systems
- Secure VPNs for remote access
These steps form a security wall to ensure unauthorized personnel cannot gain access to the ERP system.
9. Restrict Third-Party Integrations
Third-party integrations can boost capabilities, but also expose vulnerabilities. Check how secure the third-party vendors are and if their tools actually go well with your ERP system.
One such example included a healthcare organization that found an unencrypted third-party billing system, putting patient data at risk. In such scenarios, they can lessen that threat by migrating to a secure vendor.
10. Backup Data Regularly
Regular backups will allow you to recover your ERP data in case of a cyberattack or system failure. Each backup should be stored in a safe, off-site location and tested regularly for reliability. A small retail business successfully resumed operations after a ransomware attack because it had a recent backup of its ERP data.
11. Use Cloud-Based ERP Systems With Built-In Security
Cloud-based ERP solutions have robust built-in security features, which is why many businesses are switching to them. These features include:
- Automatic updates
- Data encryption
- Scalable security measures
For example, a startup chose a cloud-based ERP solution to ensure compliance with industry regulations and safeguard customer data.
12. Work With Security
Experts In some cases, in-house teams may not know that it is necessary to manage ERP security well. Hiring cybersecurity professionals or consultants can provide insights and solutions based on the specific needs of your business. For example, an automotive company recruited security consultants who helped them to deploy advanced threat detection systems in their ERP — mitigating their attack surface effectively.
13. Establish Disaster Recovery And Incident Response Plans
A security system is never unbreachable, and problems may happen. An organization must have a disaster recovery and incident response plan in advance. This plan should outline:
- Steps to recover data from backups.
- Procedures for restoring system access.
- Details on how they will communicate if they suffer a breach.
An example would be a financial institution with a disaster recovery plan that enabled them to quickly restore their ERP system following a breach, reducing downtime and financial impact.
14. Know The Industry Regulations And Ensure Compliance
The security in an ERP also includes compliance with governing laws tailored to your industry, such as GDPR, HIPAA, or SOX. Many of those regulations contain stringent data protection and security requirements, which can confer a substantial amount of protection from outside threats to your ERP system.
In another example, a healthcare organization ensured HIPAA compliance by including encryption in their ERP, which offered protection against information breaches, maintaining confidentiality, and ensuring patient trust.
15. Secure Mobile Access To ERP Systems
The rise of mobile devices makes remote access to your ERP system a necessity, but it also leads to new vulnerabilities. Tablets and smartphones used by employees to access ERP data can pose significant security risks if not properly safeguarded.
You can prevent and control access, enforce security policies, and wipe data remotely in case a mobile device is lost or stolen by deploying mobile device management (MDM) solutions.
Improving ERP Security With A Focus On Continuous Commitment To Cyber Resilience
