Is Shared Hosting Secure?

Shared hosting is a common and budget-friendly option for small businesses or websites with low traffic.

While it offers benefits like affordability, it's important to be aware of potential security issues.

“Despite these security worries, it's possible to make your website secure on shared hosting.”

All you need to do is check and double check reviews of the hosting company you're considering to ensure they have strong security measures for their shared hosting package.

Keep reading to learn more about shared hosting's security aspects.

Shared hosting is affordable for businesses, but before choosing it, consider its security risks.

DDoS Attacks

DDoS attacks or distributed denial-of-service attacks affect the performance of the site and its uptime by flooding traffic to a particular server.

An attack could randomly target a site or specifically choose one. A DDoS attack overloads the server, possibly causing all hosted sites to stop working or crash.

Security Issues

With shared hosting, always consider security risks. If one site on a server is compromised, all sites could be affected, posing a threat to your customer privacy and data security.

Protection

In shared hosting, you have fewer security options than dedicated or VPS hosting, where admins can add applications and change settings, because your control over the server is limited.

Shared IP address

If another website on your server engages in spam or illegal activities, your shared IP could be blacklisted. This may lead to firewalls blocking access to your site. Choosing shared hosting with a dedicated IP can solve this problem.

Resource Limitation

Shared hosting environments have resource limits that can affect your site's performance and security. If one site uses too many resources, it can slow down or crash the server, impacting all sites.

Data Breaches

Shared hosting increases the risk of data breaches since multiple sites share the same server. A flaw in one site can expose data on others. Regularly back up your data and choose a hosting provider with strong encryption and data isolation.

Software Vulnerabilities

Shared servers often run common software, making them targets for attackers. A single vulnerability can compromise all sites on the server. Opt for a hosting provider that keeps software up-to-date and regularly applies security patches.

Limited Customization

Shared hosting has limited customization for security settings. You may not be able to install custom security software or configure advanced protocols. Assess your security needs and look for providers that offer additional security features or managed services.

Online websites can be protected using various software and hardware security measures. With cyberattacks increasing, it's crucial to improve security quickly.

Let’s quickly review strategies you can employ to boost your shared hosting security.

1. Regular backups

One of the best ways you can protect yourself against cyberattacks is to regularly backup your site.

Keep your security software and applications updated to efficiently combat new threats. Your website will do a lot better if you do backups on your website more frequently.

2. Avoid untrusted sources

In the race to save some money or put out new functionalities or features, you might sometimes put security in second place.

Using free versions of paid software or downloading from untrusted sources greatly increases the risk of viruses or spyware.

Ensure you avoid suspicious free deals and sources that aren’t trusted, tempting as they might seem.

3. Regulate permissions and user roles

The most common security breach comes from website users. When giving out user permissions, be cautious.

Use two-factor authentication and enforce strong password policies for added security.

A single inexperienced user's mistake could compromise your entire website, so limit administrator privileges to trusted individuals only.

4. Use a Web Application Firewall (WAF)

A Web Application Firewall (WAF) serves as a critical security measure, inspecting HTTP traffic to ensure the safety and integrity of web applications.

• Protects against SQL injection
• Mitigates cross-site scripting (XSS)
• Prevents cookie poisoning
• Reduces the risk of web-based attacks
• Adds an extra layer of security

5. Implement SSL Certificates

Secure Sockets Layer (SSL) certificates encrypt the data transferred between your website and its users.

This ensures that sensitive information like login credentials and payment details are protected from interception by malicious actors.

An SSL certificate is also essential for building user trust and improving your website’s SEO ranking.

6. Regularly Update Your CMS and Plugins

Content Management Systems (CMS) like WordPress, Joomla and Drupal are frequently targeted by hackers.

Ensure that your CMS, along with any themes and plugins, are always up to date.

Developers release updates to fix security vulnerabilities, so regular updates are critical to maintaining a secure website.

7. Monitor Your Website for Suspicious Activity

Regularly monitor your website for unusual activity such as unauthorized login attempts, changes to files, or unexpected increases in traffic.

Using tools like intrusion detection systems (IDS) and security plugins can help you identify and respond to potential threats promptly.

8. Use Secure File Transfer Protocol (SFTP)

Instead of using FTP, which transmits data in plain text, opt for SFTP. Secure File Transfer Protocol encrypts both the commands and the data, preventing sensitive information from being intercepted during the transfer process.

Security standards are integral to the well-being of any website, big or small.

The first step to protecting your website is to educate yourself. Below, we’ll briefly explore the security levels of other types of hosting.

• Hosting for WordPress: Hosting for WordPress is secure if owners prioritize their site's security by following best practices, such as regular updates, installing security plugins, and choosing safe themes and plugins.

• Dedicated hosting: Dedicated hosting offers fewer security concerns but requires the customer to manage them. It's best suited for tech-savvy website owners familiar with cybersecurity.

• VPS hosting: Virtual Private Server (VPS) hosting provides a middle ground in terms of security. VPS hosting offers more isolation than shared hosting. That said, users must still actively secure their space with firewalls and regular security checks.

• Cloud hosting: Cloud hosting provides scalable security, including automated backups, encryption, and threat detection. However, the shared nature of cloud environments can necessitate additional security protocols to safeguard data.

Shared hosting often comes with its share of myths and misconceptions, especially concerning security.

Let's debunk some of the most common ones to provide a clearer picture:

1. All shared hosting is equally vulnerable

Security levels can vary greatly among shared hosting providers.

While shared resources mean shared risks, many providers implement stringent security measures to protect all websites on a server.

2. A single compromised site compromises all

Although one vulnerable site can pose a risk, reputable hosting services use isolation techniques to limit potential cross-site contaminations.

3. Shared hosting means shared IP addresses always lead to blacklisting

While sharing an IP address with spammy sites can be risky, most hosting providers monitor and manage this issue proactively to prevent such outcomes.

4. You have no control over your site's security on shared hosting

Even in a shared environment, there are numerous steps you can take to secure your site, such as installing security plugins, using strong passwords, and regularly updating your site's software.

5. SSL certificates are unnecessary on shared hosting

Regardless of the hosting type, SSL certificates are crucial for encrypting data and providing a secure connection for your website visitors.

The landscape of shared hosting security is evolving rapidly, driven by both technological advancements and emerging threats.

Here's what to expect in terms of trends and innovations:

• Advanced Isolation Technologies: Hosting providers are increasingly adopting advanced isolation methods like containers and virtualization to prevent threats on one website from spreading to others on the same server.

• Automated Security Updates and Patch Management: Automation in updating software and patching vulnerabilities will become more prevalent, minimizing the window of opportunity for attackers to exploit outdated systems.

• AI and Machine Learning for Threat Detection: AI and machine learning algorithms will play a significant role in detecting and neutralizing threats in real-time, predicting potential vulnerabilities before they can be exploited.

• Enhanced DDoS Protection: With DDoS attacks becoming more common, shared hosting providers will invest in more robust DDoS mitigation tools and infrastructure to protect their networks and hosted websites.

• Blockchain for Enhanced Security: Some hosting providers may start to leverage blockchain technology to secure transactions and data exchanges between the server and users, offering an unprecedented level of security and transparency.

• Increased Use of CDN Services: Shared hosting services are increasingly integrating CDNs to boost site speed, performance, and security by spreading out the load and reducing the impact of DDoS attacks.

Like any hosting, shared hosting is vulnerable to hacking. Protecting your site involves understanding the importance of securing your site, server, and IP address.
