The Complete Guide to Website Security: Protecting Your Site from Cyber Threats
Keeping your website secure may feel like an effort that's out of your league, but as a responsible site owner, it’s something you can’t overlook. After all, hackers are constantly looking for easy targets, and the last thing you want to discover is a compromised site.
The long-term losses from data breaches can be devastating, affecting both your business and your reputation:
Consistently managing your website security is essential. Regular maintenance of your source site makes it increasingly difficult for attackers to infiltrate.
If you're clueless about cyberattacks, this guide is here to help. We’ll walk you through simple steps to protect your website and keep your online business safe in 2025.
What is Website Security?
Website security or cybersecurity is all about protecting your site from cyberattacks and ensuring it stays safe for your visitors. It involves practices such as preventing threats, fixing vulnerabilities, and using the right tools to anticipate potential risks.
An ongoing effort, website protection is a process that defends your site against malware, hackers, phishing scams, and errors. A secure website protects your business, user's data, and customer data.
Why is Cybersecurity Important?
Your website isn’t just a place for visitors to check out your products or read your blog. It’s a vault for sensitive customer data, which, if breached, can lead to disastrous consequences. The proof of pudding is in the data:
- Dark web selling: The dark web has become a marketplace for cybercriminals to sell stolen customer data, including passwords, names, and financial information, fueling the rise in cyberattacks
- Rising attacks: Gartner forecasts that by 2025, 45% of global organisations will experience some form of supply chain attack. Another report claimed over 30,000 new vulnerabilities WERE reported in 2024, a 17% increase from 2023
- New technology = More cybercrime: A recent report suggests new tools and technologies will create new opportunities for criminal networks, making cybercrime an increasingly low-risk and low-cost way for organised crime to make money. For instance, phishing attacks can now be easily translated into minority languages using AI!
- Higher costs: Cybercrime costs are expected to reach over $23 trillion annually by 2027, up from $8.4 trillion in 2022. Plus, identity fraud losses amounted to $23 billion in 2023.
- Greater resolution time: Fraud resolution hours surged in 2023. While it took consumers an average of six hours to resolve identity fraud issues in 2022, this jumped to nearly 10 hours in 2023, causing significant frustration for consumers and businesses:
The takeaway: Reportedly, cybersecurity will continue to be a major concern in 2025, with ongoing threats to tech systems and services, especially in key areas like finance and communications.
Common Cybersecurity Threats and Causes 101
| Common Cyber Threats | Why It Happens | Who Is Most Affected |
| Third-Party Integration | Third-party integrations, like plugins, ads, or external widgets, often have vulnerabilities that hackers exploit.
These integrations can contain outdated code, malware, or poorly written APIs. If a third-party integration isn't regularly updated, it can open the door for cybercriminals. |
Small to medium-sized businesses, blogs, e-commerce websites, and any site using third-party tools (payment gateways, analytics, etc.).
Hackers exploit the lack of secure code in integrations, and users of these tools may not be aware of potential threats until it's too late. |
| Software Vulnerabilities | Software often has bugs or unpatched vulnerabilities that developers have not yet fixed, either because they haven’t identified them or because updates are neglected.
Cybercriminals can exploit these vulnerabilities to run malicious scripts, inject malware, or gain unauthorised access. This happens especially when websites run on outdated versions of popular content management systems (CMS) like WordPress, Magento, or Joomla. |
Websites using outdated software, plugins, or extensions. If your site uses unpatched CMS software or doesn’t update regularly, you’re exposed to these vulnerabilities.
E-commerce sites, personal blogs, and smaller organisations that don't prioritise security updates are commonly impacted. |
| Weak Passwords | Many website administrators use weak, easily guessable passwords (e.g., "123456," "password," or even names and dates related to the site or owner).
These are easy for hackers to guess, and tools like brute-force attacks can quickly break them. Websites without two-factor authentication (2FA) are particularly vulnerable. |
Websites with minimal security practices. Small businesses, personal websites, and sites with a single admin or a limited team often neglect strong password enforcement, making them prime targets for cybercriminals. |
| Insecure Web Hosting | Hosting providers sometimes neglect to secure servers properly or fail to implement necessary security measures such as firewalls, malware scanners, and intrusion detection systems.
Shared hosting environments are particularly vulnerable because vulnerabilities in one account can be used to target others on the same server. |
Websites hosted on low-security shared hosting platforms or without secure infrastructure. Smaller businesses or those on budget hosting plans are especially at risk since they may cut corners on security to reduce costs. |
| Transport Layer Misuse | Websites that don't use HTTPS or improperly configure SSL/TLS encryption leave their traffic exposed. In this case, data, including login credentials and credit card information, can be intercepted or altered by attackers using man-in-the-middle attacks (MITM).
These attacks can occur if users are tricked into accessing an unsecured network or website that appears legitimate. |
E-commerce websites, login portals, banking sites, and any service that exchanges sensitive information. Users entering personal data on non-HTTPS sites risk exposing themselves to MITM attacks. |
| SQL Injection | If user inputs on a website (such as form fields, search bars, etc.) aren’t properly sanitised, attackers can inject harmful SQL commands into a database query.
These commands can manipulate the database, retrieve private data, or even modify or delete it. SQL injections exploit poor input validation on the server side. |
Websites with poorly designed databases or input forms that don’t properly sanitise user input. Most common on custom-built websites or poorly secured CMS platforms like WordPress or Magento. |
| Malware & Viruses | Attackers exploit website vulnerabilities (like insecure plugins or outdated code) to inject malicious software onto the site. This malware can then steal personal data, create botnets, inject SEO spam, or redirect visitors to other malicious websites.
Some malware also allows attackers to maintain access to your website by installing a backdoor. |
Websites with outdated software or poorly protected content management systems. E-commerce sites or high-traffic websites are prime targets as hackers can use malware to hijack visitor data or redirect traffic to other malicious sites. |
| Ransomware | Ransomware involves infecting a website with malicious software that locks up or encrypts vital data, forcing the owner to pay a ransom to regain access.
Ransomware can be introduced via infected plugins, compromised email attachments, or unsecured file upload fields. |
E-commerce sites, educational sites, or small businesses that store sensitive data. Websites that store sensitive personal or business data are highly attractive targets for ransomware attacks. |
| Pharming | In a pharming attack, users are redirected to fraudulent websites even if they enter the correct web address.
This is typically done by compromising the victim’s computer or DNS settings, leading users to malicious sites that steal their credentials or install malware. |
Websites that store sensitive personal information, such as banking, shopping, or email sites. Users who are unaware of pharming attacks may enter their data on fake sites without realising it. |
| SEO Blacklisting | If search engines detect that a website is infected with malware, engages in deceptive practices, or has been compromised, the site may be blacklisted.
This means the site is removed from search engine results, drastically affecting its traffic and business. |
Websites with poor security measures or sites that have been compromised and not cleaned up quickly.
This can affect any site, but e-commerce and small business sites are especially vulnerable as they rely heavily on search engine traffic. |
How to Ensure Website Protection? 12 Easy Tips
Here are practical tips to strengthen your website’s defences and keep cyber threats at bay:
Tip 1. Add Two-Factor Authentication (2FA)
Who benefits most? Anyone managing a site with multiple admin accounts or sensitive data.
Passwords alone cannot always keep your site safe. Two-factor authentication, which requires a second step, such as a text message code or app-based verification, adds another hurdle for attackers. This extra layer makes it much harder for unauthorised users to break in, even if they manage to guess your password.
Questions to ask: Are my passwords strong enough? What second authentication method works best for my site?
Pro tips:
- Use authenticator apps instead of SMS-based 2FA. These apps generate time-sensitive codes that are stored on your device and not transmitted over vulnerable networks.
- To eliminate weak links, enable 2FA for all admin accounts, including temporary or low-access accounts. Don’t stop at the site admin; ensure contributors, editors, or anyone with backend access use 2FA.
- Generate and securely store backup codes in a password manager.
Tip 2. Handle File Uploads with Care
Who benefits most? Sites accepting user-generated content like images or forms
Allowing users to upload files might seem harmless, but it’s one of the easiest ways for malicious code to sneak onto your server. If your website relies on uploads, ensure they’re stored securely and scanned for threats. You can always leverage tools like Transloadit or Filestack. If file uploads aren’t essential, disable them entirely to reduce risks.
Questions to ask: Do I really need file uploads? How can I validate and scan uploaded files?
Pro tips:
- Don’t allow just any file to be uploaded. Instead, whitelist safe file extensions like .jpg, .png, or .pdf. Block potentially harmful file types like .exe, .php, or .js
- Cap the size of uploaded files to prevent server overload. For instance, limit uploads to 2MB or less for images and 10MB for PDFs.
Tip 3. Customise Your Default CMS Settings
Who benefits most? Anyone running a CMS like WordPress, Joomla, or Drupal, especially those who rely on popular themes and plugins.
Default settings in your CMS can be a goldmine for automated attacks. Bots are designed to exploit predictable configurations. Change permissions, disable unnecessary features, and review visibility settings to make your site less vulnerable.
Questions to ask: Have I customised all default settings? Do I regularly review permissions and visibility settings?
Pro tips:
- To block automated login attempts, rename your login page (for example, /wp-admin for WordPress) to something unique, like /secure-login123.
- Limit file and folder permissions to the minimum required for functionality. For instance, whenever possible, set directories to 755 and files to 644.
Tip 4. Backup Regularly
Who benefits most? E-commerce sites, content-heavy platforms, and anyone relying on their website for revenue or reputation.
When it comes to backups, even the best-secured site isn’t immune to accidents, server failures, or cyberattacks. A solid backup system acts as your safety net, ensuring you can quickly recover and minimise downtime.
Questions to ask: Do I back up my database and files? Where are my backups stored, and are they secure?
Pro tips:
- Use plugins to schedule regular backups—ideally, daily for dynamic sites or weekly for static ones.
- Keep copies on a secure cloud service and a local hard drive. Do not rely solely on your hosting provider’s backups.
- Ensure your backup includes your database, as it stores critical content like posts, user information, and site configurations.
Tip 5. Control User Access Wisely
Who benefits most? Teams managing websites with multiple contributors.
Cybersecurity often involves minimising human errors. To this end, restrict access to your site’s admin area, giving each user only the permissions they need. Also, avoid sharing credentials—everyone should have their login. This practice helps you track activity and prevents avoidable mistakes.
Questions to ask: Who really needs admin access? How can I enforce unique logins?
Pro tips:
- Assign users specific roles with permissions based on their job function. Limit access to only the systems and data necessary for their role (think: a developer only gets access to development tools, not financial data).
- When an employee leaves or changes roles, revoke all their access to systems, applications, and sensitive data within 24 hours to prevent unauthorised access.
- Use a security tool to track user actions in real-time, focusing on suspicious activities such as accessing unauthorised data or unusual login times. Set alerts for potential security incidents.
Tip 6. Leverage the Right Security Tool
Who benefits most? Any site owner looking for automated security solutions
No one can watch their website 24/7. Security plugins like iThemes Security or Jetpack can help identify vulnerabilities, block threats, and monitor activity. For non-WordPress sites, tools like Bitdefender or Sucuri are great options. Pairing these tools with regular audits ensures you’re staying one step ahead of attackers.
Questions to ask: Which security tools fit my platform? Have I enabled all the features?
Pro tips:
- Set up automated vulnerability scans every Friday at midnight to identify unpatched software, outdated systems, and potential misconfigurations. Ensure scans cover all endpoints, servers, and network devices and follow up with remediation actions within 48 hours for any discovered issues.
- Deploy a combination of firewall solutions and endpoint malware protection tools to block unauthorised access and detect malicious activity.
- Set up real-time alerts in your SIEM system to notify security teams of critical issues such as detected malware, network intrusions, or unauthorised access attempts. Ensure alerts are configured to trigger based on high-priority threats and have an incident response plan in place to address alerts within 30 minutes.
Tip 7. Protect Your Devices
Who benefits most? Website admins and their teams
Your website’s security starts with your own devices. Malware or phishing attacks on your computer can compromise your login credentials. Install reliable antivirus software, and remind your team to do the same. A single compromised device can open the door to your website.
Questions to ask: Is my antivirus up to date? Am I cautious about phishing links?
Pro tips:
- Set up weekly full system scans on all devices to detect malware. Ensure real-time protection is active, and keep antivirus software up to date to catch the latest threats.
- Always use a VPN to encrypt your connection when accessing sensitive information over public Wi-Fi. Ensure the VPN is set to activate when connecting to untrusted networks automatically.
- Never download files from unknown or untrusted sources. Before clicking on links in emails or websites, verify their legitimacy by hovering over them and using a link scanner to check for potential threats.
Tip 8. Rotate and Strengthen Passwords
Who benefits most? Everyone managing sensitive accounts
Weak or reused passwords are a hacker’s dream. Use a password manager to create unique, complex passwords for each account. Changing them regularly adds another layer of protection, ensuring that any leaked credentials quickly become useless.
Questions to ask: How often do I change passwords? Are they unique for every account?
Pro tips:
- Aim for passwords with at least 12 characters, mixing letters, numbers, and symbols.
- Avoid using personal information like names or birthdates.
- Enable login alerts to detect unauthorised attempts.
Tip 9. Switch to HTTPS
Who benefits most? E-commerce sites and any site collecting personal information
HTTPS encrypts data between your website and visitors, preventing sensitive information from being intercepted. To secure your site and reassure users, add an SSL certificate. This is non-negotiable if you handle payment or personal details.
Questions to ask: Does my site have an SSL certificate? Is HTTPS enforced site-wide?
Pro tips:
- Many hosting providers offer free SSL certificates, so verify with your provider today to see if one is available and install it on your website. Ensure that the certificate is valid, up to date, and covers all subdomains if necessary.
- Redirect all HTTP traffic to HTTPS by configuring your web server or using a website plugin.
- Set up reminders to renew your SSL certificate before it expires, and perform regular checks to verify the certificate's validity and proper installation.
Tip 10. Leverage the NIST Cybersecurity Framework (CSF)
Who benefits most? Website owners who want a structured, long-term security strategy
To strengthen your website’s security, adopt the NIST Cybersecurity Framework (CSF), which provides a detailed, structured approach to managing risks. The CSF is built around five essential functions: Identify, Protect, Detect, Respond, and Recover. By following these functions, you can create a holistic security plan that addresses both prevention and response.
- To Identify vulnerabilities, regularly audit your website’s codebase, server configurations, and third-party integrations for weak spots. Use penetration testing tools to find potential entry points.
- Under the Protect function, implement strong, multi-factor authentication (MFA), encryption, firewalls, and regularly updated patches.
- For Detect, deploy advanced monitoring tools that track unusual traffic patterns or unauthorised access attempts and set up real-time alerts for potential threats.
- If an attack occurs, Respond with a well-documented incident response plan, including immediate isolation procedures and escalation paths.
- Finally, ensure you can Recover quickly by maintaining up-to-date backups, using offsite storage, and practising disaster recovery drills to minimise downtime after an attack.
This framework ensures you don't only address immediate vulnerabilities but also create a dynamic, evolving security strategy that adapts to emerging threats.
Questions to ask: Have I fully mapped out the risks across my entire website, including third-party services? Do I have a detailed, up-to-date recovery plan that accounts for both common and advanced attack scenarios?
Pro tip:
- Identify and prioritise critical assets like customer data and intellectual property, focusing security efforts on the highest-risk areas.
