How To Improve Website Security: 15 Tips & Tricks

You don't leave your front door wide open when you go to sleep, do you?

And yet, with your websites, that's what many of us do every day.

We build these digital storefronts and fill them with our best ideas, hard work, and customers' trust. And then what? We leave them vulnerable, out there, exposed in the dark alleys of the internet.

But here is the thing: Security is not some form of dark art relegated only to tech wizards and coding ninjas. It is a mindset – a continuing series of small, conscious decisions that add to a fortress of digital protection.

In a world where trust is currency and data breaches make headlines, your website's security isn't just a technical problem; it's a brand promise. A silent promise one makes to every visitor who types your URL in.

So, are you ready to turn your digital welcome mat into a drawbridge? To transform your website from an easy target into an impenetrable stronghold?

Good, because we explore 15 powerful ways to increase website security in the next few minutes. 

Some may surprise you; others might challenge what you thought you knew. But all of them? They're your ticket to sleeping soundly, knowing your digital home is locked up tight. Let's dive in.

Why Website Security Matters

First, let's unpack why that matters before we go step-by-step. 

Your website isn't just a digital billboard or a fancy brochure. It's your home on the web.

You wouldn't leave your front door open for anyone to waltz in, right? Same principle here.

Here's why:

Trust is fragile.

It's hard to build and all too easy to lose. 

Visitors trust you with their personal information, whether as simple as an email address or as important as credit card details. 

Break that trust, even once, and your business faces an uphill battle. 

An impressive statistic is that 80% of consumers abandon a brand if their data is misused. And that can happen in just one breach. 

Think about that for a second. Can your business afford that kind of loss?

Google is always watching.

They are not mere onlookers-search engines are the guardians.

The website's rank is adversely affected if no proper security measures, such as an unsecured HTTP connection, are taken. 

Google announced that they flag non-HTTPS sites and real effects can be seen on your SEO. Research showed that 84% of users would abandon a purchase if they knew a site wasn't secure. 

You can't afford to let something as basic as security cost you customers and your position on Google's search rankings.

It's the law.

In a post-GDPR world, protecting customer data isn't just a “nice to have” – it's the law. 

Data breaches have consequences, and more often than not, those come with hefty fines. 

In 2023 alone, GDPR fines have seen European companies fork over €2 billion. 

This is not something you treat like an optional checkbox on your to-do list; it's the law, and ignoring it could cost much more than it could cost your business.

Your reputation means everything.

Think about it: a hacked site isn't just a bad day at the office; it is a brand disaster. 

Once word gets out that your website was compromised, it spreads like fire faster than you could say “cybersecurity breach.” 

60% of small companies leave business within six months of a cyberattack. And in just one mistake – one vulnerability – the reputation you've taken years to build may well vanish into the ether.

Now that we've discussed why locking down your digital home is essential let's get to the nuts and bolts of fortifying it. The cost of not doing so is simply too high.

The Basics: Start Here

1. HTTPS: Your First Line of Defence

Remember when websites started with “http://”? That's so last decade. Nowadays, it's all about HTTPS. 

The ‘S' in that acronym means secure, and that's your gateway to encrypted connections. And, well, here's what you need to know:

• SSL/TLS certificates: They're like digital ID cards for your site. Get one. Now.
• Free options exist: Let's Encrypt offers free SSL certificates. No excuses!
• Update regularly: Certificates do expire. Set reminders for renewals.

2. Strong Passwords: No, “password123” Won't Cut It

We're all guilty of standardising a weak password between several websites. For your website, this is a big no-no. Here's how you level up:

• Length matters at least 12 characters.
• Mix it up: a mix of uppercase, lowercase, numbers, and symbols.
• Passphrases: Consider using a memorable phrase. “ILovePizzaWithExtraCheese!” is both solid and easy to remember.
• Password managers: use them. They're lifesavers.

3. Keep Everything Updated: No, It Can't Wait

Do you know those annoying update notifications? They're not there to bug you. They often contain critical security patches. Here's the deal:

• Schedule it: Updates at least once a month.
• Automate it: If the system allows for automatic updates, use them.
• Test after updating: Sometimes updates break things. Always check your site post-update.

4. WAF: Your Digital Bouncer

Consider the WAF to be that hard, burly bouncer at that very snobby club. He checks every request to get into your site, sorting the riffraff from the good stuff. Here's what you should know :

• Cloud options: Services like Cloudflare offer an easily implementable WAF.
• Rule sets: WAF relies on rule sets to identify the bad guys. Keep them current.
• False positives: Sometimes, WAF blocks good traffic. Monitor for this and adjust as needed.

5. Two-Factor Authentication (2FA): Because One Lock Isn't Enough

Remember those old spy movies when it took two keys to fire off the missile? That's 2FA in a nutshell. Here's how to make it happen:

• SMS is okay, but not great: Better than nothing, but vulnerable to SIM swapping.
• App-based is better: Google Authenticator or Authy work great.
• Hardware keys: For the paranoid (or just super security-conscious), use YubiKeys.

6. Backups: The Safety Net

Imagine waking up to find that your site's been wiped clean. Nightmare fuel, right? Regular backups are your insurance policy. Here's how to do it right:

• Frequency is critical: Daily for dynamic sites, weekly at the latest for static ones.
• Store off-site: Store backups on a different server than your site. That's just like keeping your spare key under the welcome mat.
• Backup testing: A backup you can't restore is worthless. Run periodic restoration drills.

Code-Level Security: Getting Into the Weeds

7. Input Validation: Don't Trust Anybody

Every form on your site is a potentially open door to an attacker. Look at user input as if it's radioactive. Here's how:

• Clean or sanitise inputs: Take out as much malicious code as possible.
• Validate both ends: Client-side to make it easy for the user and server-side for security.
• Parameterised queries: Prevent SQL injection using prepared statements.

8. Error Handling: Don't Show Your Cards

Detailed error messages are a gold mine for bad folks. It is the virtual equivalent of leaving your blueprint at home, open on the kitchen table, when going to work or on a holiday. Instead:

• Use generic error messages: “An error occurred” is better than a stack trace.
• Log detailed errors: Leave the guts in your log off-screen.
• Monitor logs: Periodic log analysis may be the only thing that indicates an attack has occurred.

9. API Security: Lock Down Your Data Highways

APIs – the unsung heroes of the web. But, unfortunately, they are also potential security nightmares. 

Here is how you keep them tight: 

• Rate limiting to avoid brute-force attacks. An electronic way to block excessive API calls is an approach. 
• OAuth – well, your friend here is OAuth regarding third-party access. Implement it. 
• Versioning: Keep track of API versions and deprecate old, potentially vulnerable ones.

Server-Level Security: The Foundation Matters

10. Server Hardening: Battening Down the Hatches

Your server is the bedrock of your website. A compromised server is game over. Let's prevent that:

• Minimal services: Only run what you need. Each service is a potential vulnerability.
• Regular updates: Yes, we're harping on this again. It's that important.
• Firewall configuration: Lockdown ports and only allow necessary traffic.

11. File Permissions: Who Can Touch What

In the world of servers, not all files are created equal. Some need more protection than others:

• The principle of least privilege is to give users and processes only the necessary permissions.
• No world-writeable files: They're asking for trouble.
• Use proper ownership: Files should be owned by the appropriate user, not root.

12. Database Security: Protecting Your Crown Jewels

Your database is where the good stuff lives. Protect it like Fort Knox:

• Separate database server: Keep your database on a different server from your web files.
• Strong passwords: Yes, we're mentioning this again. It's that crucial.
• Regular audits: Who has access to what? Review and revoke unnecessary privileges regularly.

Monitoring and Response: Stay Vigilant

13. Security Monitoring: Keep Your Eyes Peeled

Great, you've set up defences, but you need to know when they are being tested. Here's how to stay alert:

• Intrusion Detection Systems (IDS): These will inform you about suspicious activity.
• Log analysis: Studies have shown that regular log analysis is the best way to determine what is happening. You'll start to notice patterns and potential threats.
• Uptime monitoring: Often, the first way you'll know your site is under attack is if it goes down. Know about this immediately.

14. Incident Response Plan: Hope for the Best, Plan for the Worst

Even with all these measures, breaches can still happen. 

Having a plan might mean distinguishing between a minor hiccup and a major catastrophe. 

• It now defines roles: who does what in case of a breach and states a communication plan – how one will notify users if their data gets compromised.
• Practice makes perfect: Run drills. You don't want to be figuring this out during a real crisis.

15. Regular Security Audits: Trust but Verify

Think of this as a yearly check-up for your website. Regular audits can find problems before they become issues:

• Vulnerability scans: Nessus or OpenVAS can find weak links.
• Penetration testing: Pay some white-hat hackers to attempt to break into your site. They'll find holes you never knew you had.
• Code reviews: Fresh eyes can catch things you might have missed.

Wrapping Up: Security Is a Journey, Not a Destination

Here is the thing: Website security isn't a thing of once and for all; it is an ongoing process- a forever cat-and-mouse game with those who'd love to break in.

Remember, you don't have to do it all overnight. Start with the basics: HTTPS, good passwords, and frequent updates. You can work your way up through the more advanced techniques in time. With every step you make, your site is a bit safer.

And do not be afraid of external help. There's nothing wrong with bringing in experts if you feel overwhelmed. After all, security is too big an issue to be left to chance.

Are you ready to take your website from a digital sitting duck to Fort Knox? Of course, you are! Now go forth and secure that site. Your future self (and your users) will thank you.
