Security That Makes Sense for Day-to-Day Operations
When people hear “ERP security”, they often picture complicated technical controls. In reality, good security is most effective when it's built into everyday workflows: staff can log in quickly, access is controlled, mistakes are recoverable, and suspicious behaviour is easy to spot.
This guide breaks down a few security features and habits that matter most in practical terms, especially for environments with shared PCs, moving staff, and sensitive customer or supplier information.
FIDO Security Keys for Shared Shopfloor Computers
If your shopfloor staff move between workstations (or share them), passwords quickly become a weak point. People reuse them, write them down, or share them to avoid slowing down the day.
FIDO USB security keys solve this in a simple way. A user plugs in a small key, taps it (or uses a fingerprint), and the system verifies they're genuinely that user. There's no guessable password to brute force, and the login process is typically quicker than typing complex credentials.
- Faster sign-in for shared computers
- Strong protection against stolen credentials
- Reduces risk from weak or reused passwords
Login Throttling and Lockouts to Stop Brute Force Attempts
A basic (but common) weakness is allowing unlimited login attempts. Attackers can automate password guessing and keep trying until they get in.
Login throttling limits how many failed attempts can be made before an account is temporarily locked or further attempts are delayed. That one control alone can make brute-force attacks impractical.
IP Whitelisting and Two-Factor Authentication
IP whitelisting goes a step further by restricting access to trusted networks. That means even if a password is compromised, an attacker outside your approved locations can't log in.
Two-factor authentication (2FA) adds a second step during login, so a password alone isn't enough to access the system. It's one of the most effective upgrades most organisations can make.
These protections are especially important when your system contains sensitive operational data, customer drawings, pricing, or proprietary specifications.
Are Users Your Biggest Vulnerability?
Some of the most damaging security incidents aren't technical at all, they're caused by human error. Social engineering attacks rely on urgency and credibility to pressure staff into doing something unusual.
A few simple habits reduce risk massively:
- Verify who's calling before sharing information or making changes
- Use your records to confirm phone numbers and email addresses
- Be cautious if a request involves a new email address or different bank details
- Treat urgency and pressure as warning signs
If something feels off, step away for a moment, sanity-check it with a colleague, and escalate to a line manager if needed.
Permission Controls and Least Privilege
Not every user needs access to every feature. The “least privilege” approach gives staff only what they need to do their job, nothing more.
This reduces risk in two ways: it limits the damage from compromised accounts, and it reduces accidental changes by keeping destructive actions restricted to the right roles.
It can also make the system easier to use, fewer irrelevant buttons and options means less confusion and fewer mistakes.
Soft Deletion, Audit Logs, and Fast Recovery from Mistakes
In operations, mistakes are inevitable. What matters is how quickly you can recover without disruption.
Soft deletion means data looks “deleted” day-to-day, but can be restored easily if it was removed accidentally. Combined with audit logs, you also gain traceability: who did what, when, and what changed.
- Restore accidentally deleted records quickly
- Track user actions for accountability and troubleshooting
- Support compliance and internal process reviews
End-to-End Encryption: Protecting Data in Transit and At Rest
Modern ERP and MRP systems handle a large amount of sensitive operational data, from customer documents and drawings to purchase orders and internal records. Protecting that information requires security both while data is moving and while it is stored.
When users access the system through a browser, communication with the server is protected using TLS/SSL encryption. This ensures that information travelling between the user and the platform cannot be intercepted or read by third parties while it moves across the network.
Protection shouldn’t stop once the data arrives. Information stored on disk is also encrypted at rest, meaning the underlying files remain protected even if the storage itself were accessed directly. Industry standards such as AES-256 encryption are commonly used to safeguard stored data.
Together, these two layers ensure that data remains protected both in transit and while stored, reducing the risk of exposure at any stage of the system.
Final Thoughts
Good ERP and MRP security isn't about making life harder for the people using the system. It's about reducing risk with controls that fit the way operations actually run: shared workstations, fast logins, tightly controlled access, and strong recoverability when things go wrong.
If you're reviewing a platform or assessing your current setup, start with the basics above. Small improvements like throttling, 2FA, and sensible permissions often deliver the biggest real-world security gains.
