Ecommerce Security: A Comprehensive Guide [Security Measures + Threats & Issues]

Ecommerce security is crucial for success in the industry, as cyber-criminals frequently target online businesses. In fact, in 2018, online businesses experienced a significant 32.4% of all successful cyber attacks. It’s essential to implement robust ecommerce security protocols and measures to ensure the safety of your online business.

Ecommerce Security Measures to Protect Your Website 

Did you know?

According to DWG, websites experience hacking attempts every 39 seconds, resulting in 50,000 website hacks daily.

Implement Strong Password Practices

One often overlooked but essential tip is to ensure that you and your customers create strong passwords. Strong passwords typically consist of at least eight characters, including a combination of upper and lower case letters, numbers, and special characters.

Deploy Device Protection

Installing trusted antivirus software, maintaining secure networks with firewalls, and regularly updating these systems add an extra layer of security to safeguard your data and prevent interference on your ecommerce platform.

Establish a Virtual Private Network (VPN)

A virtual private network, or VPN, offers a secure method for transmitting data over public networks, including potentially unsecured internet connections.

It’s important to understand that the internet isn’t always as safe as it may seem. Remember the Heartbleed Bug incident in 2014? 

Taking additional precautions against online threats is crucial, especially if your goal is to provide an outstanding online shopping experience for your users and customers. 

This is because achieving this goal involves handling a significant amount of sensitive information that you can’t afford to jeopardize.

Tip: Setting up a VPN connection helps maintain the security of your online connection and keeps your data confidential.

You might be familiar with VPNs as tools to protect your online privacy. However, VPN connections can be used to safeguard your corporate network. VPNs were initially developed to allow remote workers to connect to their company’s network while maintaining security.

Enhance Website Security with SSL Certificates

SSL (Secure Sockets Layer) certificates are essential files that establish a connection between a key and data transmissions across various network routes. 

These certificates are particularly associated with safeguarding sensitive information like credit card details and ensuring secure transactions for routine queries. 

SSL certificates employ encryption to shield data, preventing it from being intercepted during transit between different endpoints. In essence, the data you transmit from your end to the server remains secure.

If you intend to conduct any form of online business through your website, SSL certificates are a necessity. They ensure that every transaction occurring on your website is protected. 

Furthermore, they offer you a certificate of ownership, which helps deter hackers from using your site for fraudulent phishing activities.

Use Firewalls Software and Plugins

The Hacker News reported that a zero-day vulnerability in the WPgateway plugin led to attacks on over 280,000 WordPress sites.

Firewall software and plugins serve as gatekeepers, permitting trusted traffic while keeping untrusted connections at bay from an ecommerce site. 

By regulating the traffic flow, firewalls facilitate the detection of anomalies and prevent them from infiltrating your network. It makes firewalls highly effective in protecting against cyber threats such as XSS, spam, and malicious SQL injections.

Employ Antivirus and Antimalware Software

Attackers frequently exploit stolen credit card information to place unauthorized orders, putting your online store at risk of facilitating fraudulent activities. 

Antivirus and antimalware software use advanced algorithms to identify malicious transactions and offer fraud risk scores to assess transaction legitimacy. Regularly scanning your website can significantly reduce the risk of malware attacks.

Implement HTTPS

HTTPS has become the established industry standard for online security. Websites that persist with the older HTTP protocol may encounter adverse consequences and increased vulnerabilities to online threats. 

In the past, businesses typically restricted HTTPS usage to their payment gateways handling sensitive data.

Due to the growing concerns about password security, ecommerce store owners are now making their entire websites secure with HTTPS. This ensures that not only the payment sections but also all other pages on their websites are protected.

Furthermore, ensuring site security goes beyond merely safeguarding payment data; it also encompasses protecting the personal information of your customers.

Multi-factor Authentication

In the past, online security relied on a single way for users to prove their identity for ecommerce. But today, it’s essential for all ecommerce businesses to adopt multi-factor authentication. This extra layer of security ensures there are no openings for hackers to target your website.

Regularly Update Your Website

Web developers frequently release security updates to fix vulnerabilities and address security issues. So, it’s crucial to update the core software of your ecommerce site to prevent hackers from exploiting these weaknesses.

Also, make sure to keep an eye on and update your site’s plugins and themes. Updates typically include fixes for known problems and may add new features.

To simplify the process and save time, enable automatic updates for your website. It not only streamlines maintenance but also ensures that outdated software isn’t running on your site.

Perform Timely Backups

Regularly backing up your website is essential to safeguard against issues like database corruption or security problems. Determine a backup schedule based on how often you add new content and make changes to your website design.

While many hosting providers offer automatic backups, it’s a good practice to download copies of your website’s files and database regularly. In case of unexpected events, having site backups will prevent data loss and the need to start from scratch.

Ecommerce Security Threats and Issues 

Did You Know? 

In 2022, both Uber’s AWS account and corporate Slack account were compromised when a contractor’s corporate password, which had been acquired, was used for unauthorized access.

Ecommerce businesses face various security threats and security issues that need careful protection. Among the common security concerns are hacking, unauthorized use of personal data, monetary theft, phishing attacks, inadequate service provision security, and credit card fraud. 

Let’s look into some of the typical challenges that often plague online businesses.

Financial Frauds

Online businesses have long been targets of financial fraud. Hackers carry out unauthorized transactions, leaving a significant financial trail of losses in their wake. 

Some scammers even attempt fake refunds or returns, a practice known as refund fraud. 

For example, Johny takes advantage of fraudulent schemes. He recognizes that exploiting friendly fraud is a convenient method to buy a product, use it, and then request a refund to retrieve his money, so he engages in such activities!


The Shields healthcare data breach, reported in 2022, stands as the most significant data breach of the year, impacting more than 2 million individuals.

While email is a powerful tool for increasing sales, it is also a favored medium for spammers. Additionally, comments on your blog or contact forms can become open invitations for online spammers to leave malicious links that can harm your website. 

Spammers often distribute these links via social media inboxes, waiting for unsuspecting clicks. Spam not only poses a website security threat to your website but also impacts its loading speed.

Phishing Attacks 

Phishing is a prevalent security threat in ecommerce. Hackers impersonate legitimate businesses and send deceptive emails to your customers, tricking them into disclosing sensitive information. 

They create fake replicas of your legitimate website or use other strategies to convince customers that the request is coming from your business. 

Common phishing techniques involve sending emails to your customers or team members with messages like “you must take this action.” 

Success in this technique depends on customers following through with the action, providing hackers access to their login information and other personal data for exploitation.


While certain bots genuinely crawl the web with the intent to assist in website ranking, others are specifically designed to scrape pricing and inventory data from websites.

Hackers use this information to manipulate your online store’s pricing or gain control of high-demand inventory in shopping carts, ultimately leading to decreased sales and revenue.

Distributed Denial of Service (DDoS) Attacks

Distributed Denial of Service (DDoS) attacks and Denial of Service (DOS) attacks are aimed at disrupting your website and affecting overall sales. 

These attacks overwhelm your servers with numerous requests until they become overwhelmed, causing your website to crash.

Brute Force Attacks

Online store admin panels are prime targets for brute force attacks, where attackers attempt to guess passwords through trial and error. 

They use programs to establish connections with your website and systematically try every possible password combination. 

Protecting against such attacks involves using robust, complex passwords and regularly updating them.

SQL Injections

SQL injections are cyber-attacks that target query submission forms to access your database. Attackers inject malicious code into your database, retrieve data, and sometimes delete it.

XSS (Cross-site Scripting)

Hackers infect your online store with malicious code to target website visitors. Implementing a Content Security Policy is a way to defend against these attacks.

Trojan Horses

Trojan Horses may be downloaded onto the systems of both administrators and customers, posing a severe network security threat. Attackers use these programs to steal sensitive information from affected computers.

Internal Ecommerce Security Risks to Be Cautious About

Not all security threats originate from external sources. Ecommerce businesses should remain vigilant about a range of internal threats, some of which are unintentional.

Employee Negligence

Unfortunately, many cybersecurity breaches result from simple human oversights. These occur when employees do not stick to established security protocols and practices, like using weak passwords, clicking on suspicious links or attachments, or sharing sensitive information with unauthorized individuals.

Employee Sabotage

On the opposite end of the range from negligence lies intentional sabotage by employees. While it’s not always possible to prevent disgruntled employees, limiting access to sensitive data, enforcing strong password requirements, and conducting regular access reviews can help minimize the potential damage.

Third-party Insiders

This extends the concept of employee sabotage to external parties who collaborate with your business. Contractors, vendors, or even customers may inadvertently expose themselves to attackers, who can then introduce threats into your systems.
