You don't need to be a security expert, but as a business owner, you need to understand web security fundamentals. A security breach can damage your reputation, cost you customers, and even result in legal liability. Here's what you need to know.
SSL Certificates: The Basics
SSL (the padlock in your browser) encrypts data between your website and visitors. It's essential, not optional.
Without SSL:
- Google marks your site as "Not Secure"
- Customer data can be intercepted
- You lose trust and conversions
- Search rankings suffer
Most hosting providers offer free SSL through Let's Encrypt. There's no excuse not to have it.
Password Security
Weak passwords are the most common vulnerability. Implement these practices:
- Use unique, strong passwords for every service
- Enable two-factor authentication wherever possible
- Use a password manager (LastPass, 1Password, Bitwarden)
- Never share credentials via email or chat
- Regularly audit who has access to what
A single compromised password can cascade into major problems.
Keep Everything Updated
Outdated software is vulnerable software. This applies to:
- Your CMS (WordPress, etc.)
- Plugins and extensions
- Themes and templates
- Server software and PHP
- Your own computer and devices
Set up automatic updates where possible. Check for updates at least weekly for critical systems.
Backup, Backup, Backup
Backups are your insurance policy. Ensure you have:
- Automatic daily backups at minimum
- Backups stored in a separate location
- Tested restore procedures (backups are useless if you can't restore)
- Multiple retention points (not just the latest backup)
When something goes wrong, a good backup is often the only solution.
Common Attack Vectors
Understanding how attacks happen helps you prevent them:
- Phishing emails that trick you into revealing credentials
- Brute force attacks guessing passwords
- SQL injection through unvalidated form inputs
- Cross-site scripting (XSS) via malicious code injection
- Vulnerable plugins or outdated software
Most attacks exploit known vulnerabilities and human error, not sophisticated hacking.
What to Do If You're Breached
Have a plan before you need it:
1. Don't panic, but act quickly
2. Identify what was compromised
3. Change all potentially affected passwords
4. Restore from a clean backup if needed
5. Notify affected users if customer data was exposed
6. Document what happened for future prevention
7. Consider professional security audit
Web security isn't about being paranoid. It's about implementing sensible practices that protect your business and customers. The basics, SSL, strong passwords, updates, and backups, prevent the vast majority of security issues. Get these right and you're ahead of most businesses.
