Guest post 26.3.2024. Reading Time: 6 minutes

Ecommerce websites face multiple cyber threats, ranging from malware injections and DDoS attacks to phishing scams and data breaches which can jeopardize sensitive customer information, cause financial losses, and damage the company’s reputation.

When an eCommerce site is compromised, it shakes customer confidence, leading to decreased sales and potentially legal ramifications, affecting its credibility and trustworthiness in the eyes of both current and prospective customers.

Recovering from such damage requires time, resources, and a concerted effort to rebuild trust.

Therefore, securing an eCommerce platform should be a paramount concern for business owners and decision-makers within these companies.

In this article, let’s look at seven essential tips for enhancing your ecommerce website security, aimed at safeguarding your business against online threats.

1. Update your software and platforms

eCommerce websites typically work with a myriad of external tools and plugins to enhance their functionality, offering features from inventory management and payment processing to customer relationship management.

These third-party solutions help deliver a more personalized experience to their buyers through functionalities such as recommending products they might actually want and offering personalized pricing through configure, price, quote features, making them essential in most eCommerce workflows.

However, they also introduce potential vulnerabilities. Outdated plugins, APIs, or even the eCommerce platform itself can serve as gateways for cybercriminals to exploit security flaws, leading to data breaches and unauthorized access to sensitive information.

Cyber attackers frequently target known vulnerabilities in older versions of software, counting on the delay in updates. To mitigate these risks, eCommerce business owners and decision-makers are advised to adopt a proactive approach to software maintenance.

This includes regularly updating your eCommerce platform, Content Management System (CMS), plugins, and any back-end software that your site relies on. Enabling automatic updates, where available, can significantly reduce the window of opportunity for cyber attackers.

Additionally, subscribing to security bulletins for your software platforms will keep you informed about new updates or patches, ensuring that you stay one step ahead of potential security threats.

By implementing these practices, you can strengthen your eCommerce site’s defenses and protect your business and customers from cyber risks.

2. Implement SSL encryption

As they deal with a lot of sensitive customer data, eCommerce websites are prime targets for cybercriminals.

SSL (Secure Sockets Layer) encryption establishes a secure, protected connection between a user’s web browser and the website’s server, ensuring that any data transmitted — be it personal information, credit card details, or login credentials — remains private and secure from interception or tampering.

SSL encryption is not just about safeguarding data in transit; it’s also a trust signal to customers. eCommerce websites secured with SSL display a padlock icon in the browser’s address bar, often accompanied by the HTTPS protocol, signaling to visitors that the site is secure and their information is protected.

This boosts consumer confidence and trust, which is vital for encouraging online transactions.

It is crucial to purchase and install an SSL certificate on the eCommerce website from a reputable authority depending on the most optimal option. Make sure to choose a certificate that meets the eCommerce platform’s security needs, ensuring strong encryption standards are in place. Importantly, SSL should be implemented across all pages of the site, not merely the checkout process, to ensure complete protection of user data throughout their browsing session.

3. Adopt strong password policies

Weak passwords stand out as the low-hanging fruit for cybercriminals, offering an easy pathway into the otherwise fortified realms of online businesses. Techniques such as brute force attacks, where hackers attempt every possible password combination, and dictionary attacks, using common passwords and phrases, are often employed to exploit accounts protected by weak passwords.

By enforcing the creation of passwords that are a complex mix of upper and lower case letters, numbers, and symbols, eCommerce businesses can reduce the risk of unauthorized access. Furthermore, the implementation of multi-factor authentication (MFA) adds an additional layer of security.

MFA necessitates eCommerce platform users to provide multiple verification factors before they are granted access to their accounts. As there is no single point of failure, it becomes quite challenging for hackers to break into eCommerce platforms.

Instituting these measures not only fortifies the security posture of an eCommerce site but also instills a greater sense of trust among its users, crucial for maintaining and growing an online business in today’s digital age.

4. Monitor vitals and scan for vulnerabilities

Preventing a cyberattack on an eCommerce platform is infinitely preferable to addressing the aftermath. Continuous monitoring not only aids in detecting immediate threats but also highlights vulnerabilities and areas ripe for strengthening, thereby enhancing the overall security posture of the eCommerce site.

This proactive stance involves keeping a vigilant eye on the website’s vitals, recognizing that early detection of anomalies can thwart potential hacks before they inflict harm.

You can leverage specialized tools to monitor the website’s traffic around the clock, identifying and alerting administrators to suspicious activities that could signify an impending threat. Moreover, the landscape of cyber threats is constantly evolving, making regular vulnerability scans a necessity.

Such scans are adept at uncovering prevalent security issues, including SQL injection and cross-site scripting (XSS), which are common yet potent avenues for attackers seeking to exploit weaknesses in web applications.

By implementing a regimen of continuous monitoring coupled with scheduled vulnerability assessments, eCommerce business owners and decision-makers can significantly mitigate the risk of cyberattacks.

5. Use a WAF

Operating at the edge of your network, a Web Application Firewall (WAF) examines incoming traffic to your site, filtering out malicious requests before they can reach your server. 

It protects against a plethora of web application attacks, including SQL injection, cross-site scripting (XSS), and file inclusion, by blocking malicious traffic based on a set of predefined or customizable security rules.

This ensures that only legitimate traffic reaches your eCommerce platform, safeguarding sensitive customer data and the integrity of your website.

Choosing the right WAF for your eCommerce site involves considering your specific needs and budget.

WAF solutions come in various forms, including cloud-based services, which offer scalability and ease of implementation; integrated features from your hosting provider, which can provide convenience and cost savings; and physical appliances, which may offer higher levels of control and customization.

Regardless of the type, it’s crucial to configure your WAF according to your website’s unique traffic patterns and risk profile. Properly set up, a WAF serves as a critical barrier, defending your eCommerce site from hacking attempts, thus ensuring your business remains secure and trustworthy.

6. Secure the payment gateways

Securing the payment gateways ensures the safe processing of customer transactions, protecting sensitive financial data from potential cyber threats. Given the sophisticated tactics employed by cybercriminals today, a compromised payment gateway can lead to significant financial loss, not to mention the erosion of customer trust and confidence in your brand.

The repercussions of such breaches extend beyond immediate financial damage, potentially attracting regulatory penalties and damaging the long-term reputation of your business.

The solution to safeguarding your payment gateways lies in partnering with reputable payment processors known for their compliance with the Payment Card Industry Data Security Standard (PCI DSS).

This set of security standards is designed to ensure that all companies that accept, process, store, or transmit credit card information maintain a secure environment, thereby significantly reducing the risk of data breaches.

Furthermore, it’s advisable to avoid storing payment data on your own servers whenever possible. If storing payment data is unavoidable for operational reasons, ensure that it is encrypted and access is rigorously controlled.

By implementing these measures, eCommerce businesses can secure their payment gateways, ensuring a safe transaction environment for their customers and protecting the business from potential threats.

7. Limit your access to sensitive data

Sensitive data encompasses a broad spectrum of information that, if compromised, could significantly harm the business and its customers. This includes customer personal information, payment details, transaction histories, and proprietary business data.

Ensuring that access to such data is strictly controlled and limited is not just a security measure but a fundamental aspect of trustworthiness and legal compliance for eCommerce businesses. Relevant permissions refer to the rights or privileges assigned to individuals within the organization, dictating who can view, modify, or interact with this sensitive data.

Limiting access to sensitive data to only a handful of individuals is crucial for several reasons. Firstly, it minimizes the risk of internal threats, whether malicious or accidental, by reducing the number of potential points of failure.

Secondly, it simplifies the management of data access rights, making it easier to track how data is used and by whom. This controlled approach to data access is vital for maintaining data integrity and confidentiality, crucial components in safeguarding against data breaches and ensuring compliance with data protection regulations.

Implementing strict access controls, employing the principle of least privilege, and continuously monitoring and auditing data access can help eCommerce businesses protect sensitive data effectively.

Wrapping up

eCommerce businesses need to keep their website secure to protect their organizational data, customer information, and brand reputation to set themselves up for long-term success.

As the nature of cyber threats continues to evolve, it is crucial to keep your platform and relevant plugins updated, implement SSL and WAF, enforce strong password policies with MFA, consistently monitor the vitals, partner with secure payment providers, and ensure only limited personnel have access to sensitive information such as customer financial details.

Beyond these measures, it is beneficial to stay updated on eCommerce trends and news to iteratively bolster the security of your website.
