How to Get Your Store Ready for PCI DSS 4.0 Requirements

Make sure that you're using the latest app, plugin, or tool in your store. Hackers often look for outdated systems because they know they're vulnerable.

So, always update your tools and keep any old plugins you don't need off your site. This helps close any gaps hackers might exploit.

Not everyone on your team needs access to sensitive payment information. Lock down access to only those who absolutely need it.

This way, you minimize risk by limiting the number of people accessing this data. It's simple: fewer people with access means fewer chances for data to slip through the cracks.

Think of this as adding extra locks on a door. Multi-factor authentication (MFA) means having a second layer of security.

Even if someone figures out your password, they still can't get in without a second form of ID.

By requiring an additional layer, like a code sent to your phone, you make it that much harder for hackers to gain entry.

If you store any cardholder data physically, it's time to rethink that. Physical security is crucial, especially if you have employees who work with backups on-site.

Keep any paper records or hard drives with sensitive data locked in secure rooms. Ideally, aim to go paperless for everything possible—it's easier to secure digitally than with physical copies.

Track everything. Set up logging tools to keep tabs on who's accessing sensitive data.

Make it a routine to review these logs for any unusual activity.

This is your chance to catch a problem before it becomes a disaster. Monitoring doesn't just catch bad actors; it also lets you see any access errors or accidental permissions.

Security is not "set it and forget it." Schedule regular scans and vulnerability tests.

If you can, get a third-party assessment. These scans are your way to ensure your defenses are tight.

Vulnerability testing is like a fire drill, and it's better to spot a weak spot now than during an actual crisis.

Every person on your team should know the basics of security. Make a policy that's clear, easy to understand, and relevant to everyone.

Regularly review this policy and make updates when new security practices come out. But, having a policy is not enough. Instead, security m
