ERP Data Security

1. ERP Data Threats Every Executive Must Know

Before planning defenses, executives must understand that the threats facing ERP systems come in many forms — not limited to external attacks, but also including threats from within the organization itself.

Ransomware — Ransom-Demanding Malware

Ransomware is malware that encrypts all system data and demands ransom in exchange for the decryption key. In 2024-2025, numerous Thai businesses fell victim to ransomware attacks specifically targeting ERP systems, causing operations to halt for weeks. Accounting data, purchase orders, and all inventory records were locked, rendering all operations impossible. Damages ranged from hundreds of thousands to millions of baht.

Phishing — Deceptive Emails

Phishing is the most common channel hackers use to breach ERP systems — sending fake emails that appear to come from executives, business partners, or suppliers, tricking employees into clicking links and entering their passwords. Once hackers obtain these credentials, they can immediately access the ERP system. Security reports indicate that over 90% of system breaches begin with a phishing email.

Insider Threats — Threats from Within

Not all threats come from outside. Disgruntled employees, former staff whose access was never revoked, or even well-meaning employees who make mistakes are all risks. For example, an accountant with full access to financial data could exfiltrate information without authorization, or a former employee who still has active system access.

Data Breach

Data breaches can result from various causes: improper system configurations, data transmission through insecure channels, or storing data without encryption. The impact of a data breach extends beyond financial damage to include loss of credibility, lawsuits, and fines under the PDPA.

2. PDPA and ERP Systems — Legal Requirements Organizations Must Follow

Thailand's Personal Data Protection Act B.E. 2562 (PDPA) is now fully enforced, requiring all organizations that collect, use, or disclose personal data to strictly comply with its provisions. ERP systems store vast amounts of personal data — including employee, customer, and business partner information.

What organizations must do to ensure PDPA compliance in relation to their ERP system:

• Obtain Consent — Consent must be obtained from data subjects before collecting and using their data; the ERP system must have a feature to record consent
• Restrict Access — Personal data must be accessible only to authorized personnel; the system must implement role-based access controls
• Data Encryption — Personal data must be encrypted both at rest and in transit
• Data Subject Rights — The system must support requests to view, modify, delete, or transfer personal data
• Breach Notification — In the event of a data breach, the organization must notify the Personal Data Protection Commission within 72 hours
• Activity Logging — Audit Logs must record who accessed, modified, or deleted what data, and when

Organizations violating the PDPA may face fines of up to 5 million baht, imprisonment of up to 1 year, or both. Choosing an ERP system that supports PDPA compliance is therefore critically important.

3. Security Measures in Saeree ERP

Saeree ERP is built with Security by Design, employing multiple layers of protection working together to ensure your organization's data receives the highest level of security.

Encryption — Data Encryption

Saeree ERP uses AES-256 encryption — the same standard used by banks and government agencies. All data is encrypted both at rest and in transit via SSL/TLS, ensuring that even if data is intercepted, attackers cannot read it.

Role-Based Access Control (RBAC) — Access Control by Role

The RBAC system in Saeree ERP lets administrators define data access rights based on each employee's role. For example, sales staff see only customer data and orders but cannot access salary or financial statement data. The system supports permission control at the menu, function, and even field level for the most granular control.

Audit Log — System Usage Records

Every action in Saeree ERP is recorded in detail — whether it is logging in, viewing data, editing, deleting, or printing reports. These records include the username, date and time, IP address, and details of changes made, enabling retroactive auditing at any time and providing crucial evidence when anomalies occur.

2FA — Two-Factor Authentication

Saeree ERP supports Two-Factor Authentication (2FA) including OTP via SMS/Email, Authenticator Apps, and Biometric methods to add an extra layer of login protection. Even if passwords are compromised, attackers still cannot access the system. Learn more in our article on What is 2FA? Why ERP Systems Need Two-Factor Authentication

Data is the most valuable asset of any organization in the digital age. Protecting data is not optional — it is a duty.

4. Backup & Disaster Recovery

No matter how strong a security system is, no system is 100% perfect. Having a data backup and system recovery plan is therefore absolutely essential. Saeree ERP provides comprehensive backup systems as follows:

Auto Backup — Automated Data Backup

The system performs automated backups daily without human intervention. Administrators can configure backup frequency — daily, every 12 hours, or even hourly depending on data criticality. Backup data is encrypted before storage to prevent unauthorized access.

Disaster Recovery — System Recovery Plan

Saeree ERP has a comprehensive disaster recovery plan. In emergencies — whether server failure, fire, flooding, or ransomware attacks — the system can rapidly restore data from the latest backup point, with clearly defined RTO (Recovery Time Objective) to resume business operations as quickly as possible.

Cloud Storage — Cloud-Based Storage

Backup data is stored on highly secure cloud systems, separate from the primary server. Even if the primary server is damaged, backup data remains safe. Additionally, backups are stored across multiple data centers to mitigate risks from widespread disasters.

5. Best Practices for Organizations

Beyond choosing an ERP system with strong security measures, organizations must also adopt best practices to reinforce security. Here are the recommended approaches:

Train Employees Regularly

The biggest vulnerability in any security system is "people." Therefore, training employees on cybersecurity is the most critical measure. Training should be conducted at least twice a year, covering how to spot phishing emails, creating strong passwords, not sharing passwords, and reporting anomalies.

Principle of Least Privilege

Grant data access only as necessary for job functions. Not every employee should have Admin access or access to all data. Review and audit access rights regularly, especially when employees change positions, transfer departments, or leave the organization.

Keep Systems Updated

New security vulnerabilities are discovered constantly. Updating the ERP system to the latest version helps close these gaps. Saeree ERP has a dedicated team that regularly releases security patches and notifies administrators when critical updates are available.

• Use strong passwords — At least 12 characters mixing uppercase, lowercase, numbers, and special characters
• Enable 2FA immediately — Enforce for all users, especially those with access to sensitive data
• Review Audit Logs regularly — Watch for abnormal behaviors such as after-hours logins or access to data unrelated to job duties
• Prepare an incident response plan — Define clear steps for what to do when a data breach or attack occurs
• Test security systems — Conduct regular Penetration Testing to find and fix vulnerabilities before malicious actors discover them

Conclusion

ERP data security is no longer something executives can overlook. Threats are growing more numerous and sophisticated every day. The PDPA imposes severe penalties on organizations that fail to adequately protect personal data. Saeree ERP is designed to address both security and legal compliance through Encryption, RBAC, Audit Log, 2FA, and automated backup systems.
