We handle a lot of data every day. Some of it is public and some is private. Data security keeps your customers safe and allows you to follow the law.
The following are eight measures every business should take to protect their data.
Classify Your Data
First you can list what data you have and where it lives. You can write down files, databases, cloud folders and devices. Then label each item as public, internal or sensitive.
This will help you decide which data needs the strongest protection.
Use Strong Access Controls
Limit who can see or change each type of data. You can give people only the access they need for their job.
Also try to use role‑based permissions and remove access when someone leaves or changes roles.
Require Multi‑factor Authentication (Mfa)
There are many ways in which passwords can be stolen. So MFA adds a second step like a code or an app prompt to log in.
You can make MFA compulsory for admin accounts and remote access. It blocks a lot of attacks even if your password is leaked.
Encrypt Sensitive Data
Encryption hides data so only authorized people can read it. You can use encryption for stored files and for data sent over the internet.
If a device or backup is stolen, encryption makes the data much harder to use. Many cloud services offer built‑in encryption you can use as well.
Keep Software Updated
A lot of attacks use known software flaws. Make sure your apps, operating system and firmware are up to date.
You can automate updates where you can and also test them on a small group before a full rollout.
Back Up Data
You can keep backup copies of important data in separate location. When you backup, try to test your backup by restoring files and make sure they work.
Before you run large uploads, check your internet speed with a free service online so backups finish without issues.
Also keep at least one copy offline or immutable so attackers cannot change it.
Monitor Activity
Only share data with vendors that meet your security standards. You can ask for security reports and include protections in contracts.
Collect logs and monitor for unusual activity so you can spot problems early.
If you want to test how your network performs for vendor tasks, run a quick speedtest to see if your connection is stable.
Train Employees
Educate your staff about phishing and data safety. You can run short, regular training sessions and mock tests.
Write a response plan that explains who does what if a breach happens.
