Open source eCommerce platforms, such as Magento and WooCommerce, have become increasingly popular in recent years due to their flexibility, affordability, and ease of customization. However, one of the main issues with open source eCommerce platforms is the lack of built-in security features, leading to security vulnerabilities.

While open source platforms offer businesses the ability to customize their eCommerce stores to their exact specifications, this customization can also leave them vulnerable to cyber threats if security features are not implemented correctly. In addition, open source platforms are often targeted by hackers due to their popularity, which can result in security breaches and data theft.

To address this issue, businesses that use open source eCommerce platforms should ensure that they have adequate security measures in place, such as SSL/TLS encryption, secure password policies, and regular security updates. Additionally, businesses should consider working with experienced developers and security experts to implement additional security measures and monitor their systems for potential threats.

The problem with Shopify

Credit card data

Shopify is a popular eCommerce platform that offers businesses a simple and affordable way to set up an online store. However, while Shopify offers many benefits, there are also some serious security risks and concerns that businesses should be aware of.

One of the main security issues along with Shopify is the platform’s centralized architecture and data protection. This means that all data and transactions are processed through Shopify’s servers, which can make businesses more vulnerable to cyber attacks. In addition, Shopify’s shared hosting environment means that businesses may be sharing server resources with other websites, which can also increase the risk of security breaches.

To address these concerns, businesses that use Shopify should take steps to improve their security posture. This may include implementing SSL/TLS encryption, regularly updating their software and plugins, using secure passwords for user accounts, and monitoring their store for potential threats. In addition, businesses should consider working with third-party security experts to implement additional security measures and conduct regular security assessments to identify and address vulnerabilities.

Differences Between eCommerce Security and Compliance

Information security management systems

eCommerce security and compliance are two distinct but related concepts that are essential for protecting businesses and their customers from cyber threats. While both are important, they differ in their focus and scope.

eCommerce security refers to the measures that businesses take to protect customer records in their online stores from cyber threats. This includes implementing measures such as SSL/TLS encryption, security protocols, two-factor authentication, and regular software updates to prevent data breaches and other cyber attacks.

On the other hand, compliance refers to the legal and regulatory requirements that businesses must adhere to when handling sensitive data such as credit card information. Compliance standards such as the Payment Card Industry Data Security Standard (PCI DSS) and the GDPR require businesses to implement specific measures and processes to protect customer data and ensure their privacy.

While eCommerce security measures and compliance are related, they are not the same thing. Businesses must implement both ecommerce security best practices and compliance measures to ensure that they are protecting their customers’ data and complying with legal and regulatory requirements. By doing so, businesses can build customer trust, prevent security breaches, and avoid costly legal and financial consequences.

5 Most Common eCommerce Security Threats You Should Avoid

eCommerce sites are prime targets for cybersecurity threats due to the sensitive information they store, including customer data and payment information. Here are five of the most common eCommerce security threats that businesses should be aware of:

  1. Phishing scams: Phishing scams are designed to trick users into providing their personal information or login credentials. Cybercriminals may send emails or messages that appear to be from legitimate sources, such as banks or payment processors, to gain access to sensitive information.

  2. SQL injection attacks: SQL injection attacks involve inserting malicious code into an eCommerce website’s database to gain access to sensitive information. This can include customer data, payment information, and login credentials.

  3. Malware attacks: Malware attacks involve infecting an eCommerce website with malicious software that can steal sensitive information, such as credit card details, or give hackers access to the website’s backend systems.

  4. Distributed Denial of Service (DDoS) attacks: DDoS attacks involve overwhelming an eCommerce website’s servers with traffic to make it inaccessible to users. This can disrupt business operations and cause financial losses.

  5. Cross-site scripting (XSS) attacks: XSS attacks involve inserting malicious code into an eCommerce website’s code to gain access to sensitive information, such as customer data or login credentials.

To avoid these threats, businesses should implement security measures such as SSL/TLS encryption, two-factor authentication, and regular software updates. Additionally, businesses should train their employees on how to identify and avoid phishing scams and other types of social engineering attacks. Finally, businesses should work with experienced security professionals to monitor their systems for potential threats and implement additional security as needed.

Transport Layer Security (TLS), Secure Sockets Layer (SSL), and HTTPS authentication

Transport Layer Security (TLS) and Secure Sockets Layer (SSL) are cryptographic protocols that provide secure communication over the internet. They are commonly used to protect sensitive information, such as credit card details and login credentials, during online transactions.

TLS and SSL work by encrypting data that is transmitted between a user’s browser and an eCommerce website’s server. This makes it difficult for cybercriminals to intercept and steal sensitive information. In addition, HTTPS authentication is used to verify that the website being accessed is legitimate and has a valid SSL/TLS certificate.

While SSL was the original protocol used for secure communication, it has been largely replaced by TLS, which is considered more secure. TLS 1.2 and 1.3 are the most commonly used versions of the protocol, with 1.3 being the most secure.

To ensure the security of their eCommerce sites, businesses should implement SSL/TLS encryption and HTTPS authentication. This can be done by obtaining a valid SSL/TLS certificate from a trusted certificate authority (CA) and configuring the website’s server to use HTTPS. In addition, businesses should regularly update their SSL/TLS certificates and use the most secure version of the protocol available.

By implementing SSL/TLS encryption and HTTPS authentication, businesses can protect their customers data’ sensitive information and build trust in their brand. It is an essential security measure for protecting customers on any eCommerce website.

Follow payment card industry data security standard (PCI-DSS) requirements

Credit card data

The Payment Card Industry Data Security Standard (PCI-DSS) is a set of data security and security requirements that businesses must adhere to when processing, storing, or transmitting payment card and cardholder data. The standard was developed by major credit card companies to ensure the security of payment and cardholder data and information and reduce the risk of fraud and data breaches.

PCI-DSS requirements include implementing secure network and system configurations, regularly monitoring and testing systems for vulnerabilities, and restricting access to payment card data to only authorized personnel. In addition, businesses must maintain strict password policies and encrypt all payment card data.

Businesses that fail to comply with PCI-DSS requirements risk financial and legal consequences, including fines, lawsuits, and loss of customers due to damaged reputation.

To ensure compliance with PCI-DSS requirements, businesses should work with qualified security professionals to assess their systems and implement necessary security. In addition, businesses should regularly review and update their security policies and procedures to address new threats and vulnerabilities.

By following PCI-DSS requirements, businesses can protect their customers’ payment card data and avoid costly consequences associated with non-compliance.

Add Multi-Factor Authentication (MFA)

user accounts

Multi-factor authentication (MFA) is a security mechanism that requires users to provide two or more forms of authentication to access an eCommerce website online store. This can include something the user knows, such as a password or PIN, something they have, such as a mobile device or security token, or something they are, such as a fingerprint or facial recognition.

By adding MFA to an eCommerce website, businesses can significantly increase their security posture and reduce the risk of unauthorized access to sensitive information. MFA can also help prevent phishing attacks, as cybercriminals would need to have access to the user’s second factor of authentication in addition to their login credentials.

There are many different types of MFA and authentication methods that businesses can implement, including text message verification, app-based authentication, and biometric authentication. It is important to choose the right type of MFA based on the needs of the business and its customers.

To add MFA to an eCommerce website, businesses can work with experienced security professionals to implement the appropriate technology and configure it to work seamlessly with their existing systems. Additionally, businesses should educate their customers on the importance of MFA and how to set it up on their devices.

By adding MFA to an eCommerce website, businesses can improve their online security posture and protect their customers’ sensitive information from cyber threats. It is an essential security measure for any eCommerce business.

Phishing attacks

Site security

Phishing attacks are a common form of cyber attack that are designed to trick users into providing their personal information or login credentials. Phishing attacks can take many forms, including emails, messages, or fake websites that appear to be legitimate.

Phishing attacks can be devastating for eCommerce sites, as they can lead to the theft of sensitive information such as customer and payment information. In addition, phishing attacks can damage the reputation of a business and result in financial losses.

To protect against phishing attacks, eCommerce businesses should implement measures such as email security, spam filters, and email authentication protocols such as Domain-based Message Authentication, Reporting, and Conformance (DMARC). Additionally, businesses should educate their employees and customers on how to identify and avoid phishing attacks, including checking the sender’s email address, verifying website URLs, and avoiding clicking on suspicious links.

It is also important for businesses to have a plan in place for responding to phishing attacks. This may include notifying customers of the attack, resetting passwords, and contacting law enforcement if necessary.

Choose the right hosting provider

Ecommerce security best practices

When selecting a hosting provider for an eCommerce website, businesses should consider several factors, including the provider’s security, server security, uptime guarantees, and customer support. Hosting providers that offer features such as SSL/TLS encryption, regular software updates, and intrusion detection systems can significantly enhance the security of an eCommerce website.

In addition, businesses should consider the type of hosting offered by the provider, including shared hosting, virtual private server (VPS) hosting, and dedicated hosting. While shared hosting is often the most affordable option, it can also leave eCommerce sites vulnerable to security breaches due to shared resources. VPS hosting and dedicated hosting offer more control and customization options, but come at a higher cost.

Finally, businesses should choose a hosting provider that offers reliable customer support. In the event of a security breach or other issue, prompt and effective support can help minimize downtime and prevent financial losses.

Passwords

Sensitive data

Strong passwords are an essential part of password security for eCommerce sites’ security. Weak passwords can make it easy for cybercriminals to gain unauthorized access to sensitive information, such as customer data and payment information. Creating strong passwords is an important step in protecting eCommerce websites from security breaches.

Passwords should also be at least 12 characters long and should not include easily guessable information such as birthdates or common words.

In addition, businesses should encourage the use of password managers to securely store and manage passwords. Password managers can help prevent users from reusing the same passwords across multiple accounts and can generate complex, random passwords that are difficult to crack.

2FA

Whilst it doesn’t make the account 100% secure, two-factor authentication for user authentication definitely makes another massive obstacle for any rascal that managed to guess your password. It also has the massive benefit of alerting the account owner whenever someone is trying to login when they’re in the pub and their phone alerts them to enter their code for the login. At which point they know to set their beer down and change their password immediately.

Schedule Regular Site Updates

Regular site updates are an important part of software security and eCommerce security practices. Updates can include software updates, security patches, and bug fixes that address known vulnerabilities and protect against cyber threats.

Hackers are constantly evolving their tactics, so it is essential to keep eCommerce websites up to date with the latest security measures. Failure to do so can leave websites vulnerable to security breaches and data theft.
