15 Ways to Improve Your Website Security in 2023

Let’s delve into the most common website vulnerabilities and threats that modern websites face, and explore ways to safeguard your online presence.

SQL Injections:
SQL injection attacks are executed by injecting malicious code into a vulnerable SQL query. Attackers exploit weak input validation and send a crafted request to the website’s database. A successful attack alters the database query, returning desired information for the attacker instead of the expected data. In severe cases, SQL injections can even introduce malicious information into the database, leading to data breaches and unauthorized access.

Prevention: To protect against SQL injections, implement strict input validation, use parameterized queries, and avoid dynamic SQL construction.

Cross-Site Scripting (XSS):
Cross-site scripting attacks involve injecting malicious client-side scripts into a website and propagating them to users who visit the site. The danger lies in manipulating how the website displays content, forcing the victim’s browser to execute the attacker’s code. This can lead to session hijacking, data theft, and even complete site takeover if a privileged user unwittingly loads the malicious script.

Prevention: Sanitize user input, encode output, and employ a Content Security Policy (CSP) to mitigate the risks associated with XSS attacks.

Credential Brute Force Attacks:
Credential brute force attacks target login credentials to gain unauthorized access to a website’s admin area or control panel. Attackers use scripts to try various username and password combinations until they find a valid one. Once inside, they can carry out harmful activities such as spam campaigns, coin-mining, and stealing sensitive information.

Prevention: Enforce strong password policies, implement account lockouts after multiple failed login attempts, and consider using CAPTCHA to deter automated attacks.

Website Malware Infections & Attacks:
Website malware infections are among the most insidious threats, as they can infect a site discreetly and remain undetected for extended periods. Malicious code can compromise user data, deliver harmful content to visitors, or lead to search engine blacklisting.

Prevention: Regularly scan your website for malware using security tools and plugins. Keep all software up to date, including CMS, plugins, and themes.

DoS/DDoS Attacks:
A Distributed Denial of Service (DDoS) attack overwhelms a website’s network, server, or application with a deluge of fake traffic, causing service disruption or slowdowns. Even a tiny amount of traffic can be enough to successfully target vulnerable endpoints.

Prevention: Employ DDoS protection services and configure firewalls to filter out suspicious traffic. Consider utilizing Content Delivery Networks (CDNs) to distribute traffic and enhance website performance during an attack.

15 Essential Tips for Securing and Maintaining Your Website’s Security:

Securing your website is of utmost importance to protect it from potential threats. In this section, we will explore essential steps to enhance your website’s security. While this is not an exhaustive guide, it offers valuable website security guidelines to help you choose the right services tailored to your requirements.

Developing a Comprehensive Website Security Framework:
Irrespective of your business’s size, implementing a well-structured security framework is crucial for reducing overall risk and safeguarding your online assets.

Recognizing that security is an ongoing process, the journey begins with establishing a robust website security framework. This involves fostering a “culture of security” and conducting scheduled audits to ensure simplicity and timeliness in addressing potential threats.

The system encompasses a core set of five crucial functions: Recognition, Safeguarding, Detection, Response, and Restoration. Let’s delve into each function and examine the respective steps to be implemented.

During this phase, meticulous asset inventory and management practices are essential. The inventory can be further categorized into:

Once the website assets are documented, steps can be taken to audit and fortify each element against potential attacks.

Deploying preventative web security measures is of paramount importance. These measures encompass protective technologies and layers of defense. Fulfilling compliance requirements, such as PCI, is one aspect, while virtually patching and fortifying vulnerable environments are equally critical. Additionally, employee training and access control policies contribute to a robust protective shield.

Activating a web application firewall stands out as one of the most effective ways to secure your website. Thoughtfully configuring security processes and employing the right tools play a significant role in enhancing your website’s security posture.

Continuous monitoring forms the backbone of this function. Implementing monitoring tools to track website assets and receive alerts about any potential issues is vital. Monitoring should encompass:

Security scanners and tools like SiteCheck are valuable in scanning for indicators of compromise or vulnerability.

In this phase, analysis and mitigation are crucial to build an effective response. Having a pre-established incident response plan significantly contributes to handling security incidents efficiently. A well-structured incident response plan should include:

During the remediation process, anticipating the nature of malware beforehand is challenging. Cross-contamination issues in shared server environments can escalate quickly, underscoring the need for swift and decisive actions.

Ensuring a thorough preparation phase and having a reliable team dedicated to website security are indispensable elements for the success of your security endeavors.

Recovery planning is critical, encompassing a complete review of all phases in the event of an incident. Backup plans are crucial, especially in cases where prior phases may have failed, such as ransomware attacks.

Communication Strategy:
In case of data risk, promptly inform customers, adhering to relevant data protection regulations like GDPR’s reporting requirements within 72 hours of a data breach.

Automatic Backups:
Risk can never be eliminated, so ensure you have automatic backups in place to recover data quickly. Having both local and external backups provides redundancy and safeguards against hardware failure or attacks.

2. Keep Everything Updated:

Countless websites fall victim to attacks daily due to outdated and vulnerable software. It is crucial to promptly update your website whenever a new plugin or Content Management System (CMS) version becomes available. These updates often contain crucial security enhancements and vulnerability patches.
In today’s automated attack landscape, bots continually scan websites, seeking potential weaknesses. Monthly or weekly updates are no longer sufficient, as bots can exploit vulnerabilities before you get a chance to patch them. To bridge this gap, consider implementing a website firewall, which virtually patches security holes as soon as updates are released.

For WordPress websites, WP Updates Notifier is a valuable plugin that notifies you when a plugin or WordPress core update is available, keeping you informed about essential updates.

3. Use Strong Passwords:

The security of your website largely depends on your password strength. Have you considered how the passwords you use could jeopardize your website’s security?
Cleaning up infected websites often requires logging into a client’s site or server using admin user details. Surprisingly, many users still have insecure root passwords, such as “admin/admin,” leaving their websites vulnerable to attacks.

To protect against password-related breaches, avoid using passwords found on lists of breached credentials. Hackers compile these lists with leaked data and commonly used dictionary words. If your passwords match any of these compromised entries, your site is at risk.

Follow these best practices to create strong passwords:

4. One Site, One Container:

When it comes to hosting websites, one of the crucial security practices to follow is maintaining a single site per server container. Although it might seem tempting to host multiple websites on a single server, especially with so-called ‘unlimited’ web hosting plans, this approach can lead to severe security vulnerabilities. Combining multiple sites in the same location increases the attack surface and exposes your websites to potential cross-site contamination.

Cross-site contamination occurs when one site is negatively affected by the activities of neighboring sites within the same server due to poor isolation or account configuration. To understand this better, consider a server with just one site that has a WordPress installation with a theme and ten plugins. When hosting five sites on the same server, an attacker gains access to multiple potential targets, including three WordPress installations, two Joomla installations, five themes, and 50 plugins. Moreover, once an attacker exploits a vulnerability on one site, the infection can spread effortlessly to other sites sharing the server.

The consequences of cross-site contamination can be devastating. All your sites could be hacked simultaneously, making the cleanup process significantly more challenging and time-consuming. The infected sites might continuously reinfect one another, creating an endless loop of malware propagation.

Even after successfully cleaning up the infections, you’ll face the daunting task of resetting passwords. Instead of dealing with just one site, you’ll have to update passwords for all the websites hosted on that server. This includes CMS databases and FTP users associated with each site. Neglecting this step can lead to re-infections, forcing you to restart the entire cleanup process.

5. Limit User Access & Permissions to Enhance Security:

In addition to securing your website code, it’s crucial to consider the security of your users. Recording IP addresses and activity history can be valuable for forensic analysis in case of any security incidents.

The principle of least privilege is a fundamental concept for user access and permissions management. It revolves around two main objectives: using the minimum set of privileges required to perform a specific action and granting those privileges only for the time they are necessary.

When assigning privileges to specific roles, it’s essential to define what actions they can and cannot perform. In an ideal system, a role will prevent any attempts to perform actions beyond its designated scope. For example, while administrators might have the privilege to inject unfiltered HTML or install plugins, authors should have limited access based on their trust level, with separate roles and locked-down accounts.

This principle becomes particularly relevant for websites with multiple users or logins. Ensuring that each user has only the necessary permissions for their tasks is crucial. If elevated privileges are required for a specific task, they should be granted temporarily and then promptly revoked once the task is completed.

By establishing clear user roles and access rules, you minimize the risk of mistakes and reduce the potential damage caused by compromised accounts or malicious users. Moreover, accountability and monitoring play an essential role in user management. Having separate accounts for each user enables you to track their behavior through logs, identifying any unusual login times or suspicious locations, which can be indicative of unauthorized access.

Maintaining audit logs is vital to detecting any anomalous changes to your website. An audit log is a record that tracks events on your website, allowing you to identify potential security breaches and verify whether accounts have been compromised. For WordPress websites, you can utilize security plugins like Sucuri’s free Security Plugin from the official WordPress repository to assist in performing these audit logs automatically.

Understanding File Permissions:

File permissions play a crucial role in website security, defining who can perform specific actions on files. Each file has three types of permissions, represented by numbers:

To grant multiple permissions, you simply add the corresponding numbers together. For example, to allow both read (4) and write (2) permissions, you set the user permission to 6. If you need a user to have read (4), write (2), and execute (1) permissions, then you set the user permission to 7.

Different User Types

Three user types play a role in file permissions:

By properly managing user access, permissions, and file security, you can significantly enhance the overall security posture of your website, mitigating potential risks and protecting sensitive data from unauthorized access and exploitation.

6. Customize Your CMS Settings

In today’s digital landscape, Content Management System (CMS) applications are popular for their user-friendly interfaces. However, from a security perspective, default settings can pose significant risks. Most common website attacks are automated and target sites with default configurations. Fortunately, you can greatly reduce the risk of such attacks by simply modifying the default settings when installing your preferred CMS.

For instance, some CMS applications allow users to write or install various extensions freely, potentially creating vulnerabilities. To mitigate such risks, adjust settings related to comments, user permissions, and user information visibility. Additionally, pay attention to file permissions, as default settings may need to be hardened.

Whether during the initial CMS installation or later, taking the time to customize these settings is essential to fortify your website’s security.

7. Safeguard Your Website: Prudent Extension Selection

The extensibility of CMS applications is a valuable feature that webmasters appreciate, as it enables the integration of various functionalities. However, it can also introduce potential security weaknesses. The wide array of plugins, add-ons, and extensions available raises concerns about their safety and reliability.

When choosing extensions, consider the following criteria to ensure their security:

8. Safeguard Your Data: Implement Website Backups

In the unfortunate event of a hack or security breach, having website backups becomes invaluable for recovering your website. While a backup solution should not be regarded as a complete security solution, it can aid in restoring damaged files.

A reliable backup solution should meet the following requirements:

9. Strengthen Your Website: Configure Server Files

Familiarize yourself with your web server configuration files, such as .htaccess for Apache, and nginx. conf for Nginx, or web. config for Microsoft IIS. These files are powerful tools that allow you to execute server rules to enhance your website security.

Adopt these best practices for your specific web server:

By following these server configuration practices, you can bolster your website’s security and protect against potential attacks.

10. Secure Your Data Transmission: Install an SSL Certificate

SSL certificates play a crucial role in encrypting data during transit between web servers and browsers. By employing encryption, critical data remains confidential and protected from interception by malicious actors.

Types of SSL certificates, like organization SSL or extended validation SSL, can further enhance credibility by displaying your organization’s details to visitors, signaling legitimacy.

However, it is essential to understand that while SSL certificates secure data transmission, they do not directly protect your website from attacks. Implementing additional security measures is necessary to safeguard your website itself.

11. Stay Vigilant: Install Scanning & Monitoring Tools

To maintain the integrity of your website, it is crucial to continuously monitor and scan for potential threats. Alert mechanisms improve response times and enable effective damage control in the event of a security breach. Regularly reviewing logs and monitoring user actions, especially in critical areas, can help detect anomalies and unauthorized access attempts.

Triggers and alerts should be set to notify you of potential attacks, such as brute force attempts and exploit targeting. Timely application of updates and patches is essential to ensure your website remains secure against known vulnerabilities.

Implementing scanning and monitoring tools is an integral part of maintaining website security and protecting against potential threats.

12. Prioritize Personal Security: Secure Your Devices

Ensuring the security of your personal computer is paramount for website owners, as compromised devices can serve as vectors for infecting your website. Scan your computer for malware regularly, especially if your website has been hacked, as malware can spread from infected devices to web servers through text editors and FTP clients.

To reduce potential risks, uninstall all unused programs and browser extensions from your computer. These unused applications and plugins can carry privacy issues and create attack vectors. Research to understand the purpose of specific applications and remove those that are unnecessary.

By practicing personal security best practices, you minimize the chances of your own devices becoming a vulnerability for your website.

13. Safeguard Against Attacks: Utilize a Website Firewall

While SSL certificates provide data encryption, they do not protect against web application vulnerabilities or server-based attacks. A web application firewall (WAF) is designed specifically to prevent such attacks and keep your website secure, allowing you to focus on your business.

14. Employ Expert Security Services: Trust in a Website Security Solution

Choosing a reputable website security service is essential for protecting your site from potential vulnerabilities, poor access controls, and server resource exploitation.
