How secure is your online shop?

In recent years, the threat of cyberattacks on online shops has dramatically increased. Businesses of all sizes have become targets for hackers who steal sensitive customer data and can cause significant financial damage. Online security is one of the most critical issues that you should not only consider, but must address. Not every company can afford a specialist for this topic. Nevertheless, there are numerous ways in which you can ensure the security of your online shop and adequately protect it from hacker attacks.

Almost weekly, hacker attacks occur around the world, and even large companies are not always protected from such attacks. A notable example of a hacker attack on online shops is the incident at Thalia in 2022. Thalia, a popular online bookseller, fell victim to a cyberattack in which hackers used a brute-force attack to gain access to thousands of customer accounts.

What is a brute-force-attack?

In a brute-force attack, an attacker attempts to gain access to a system or account by systematically trying every possible password combination until the correct password is found. The attacker uses automated programs or scripts to try a large number of passwords in a short period of time. This type of attack is particularly effective against weak passwords, as the attacker can simply try all possible combinations until the right one is found. The more complex and longer a password is, the longer it usually takes to be cracked by a brute-force attack.

Brute-force attacks can be conducted in various ways, such as on websites, email accounts, and encrypted data. It is a widespread and dangerous method through which hackers gain access to sensitive information.

What is a magecart-attack?

Another significant phenomenon is the so-called Magecart attacks. Magecart is a group of hackers that specializes in inserting malicious code into the payment forms of online shops. Such attacks have already stolen data from millions of customers, leading to substantial financial losses for the affected companies.

The security of your online shop is not just about protecting sensitive customer data; it is also a crucial factor in maintaining your customers’ trust and thereby the success of your business. A successful hacker attack can not only lead to financial losses, but can also profoundly shake the confidence of your customers and damage your reputation.

Moreover, many countries have legal obligations to adhere to data protection regulations and to securely store personal data. Violating these regulations can result in hefty fines and jeopardize the survival of your business.

How can I enhance the security of my online shop?

You have various options to enhance the security of your online shop. Some measures you can implement on your own, while others should be handled by your hosting provider. It is always advisable to discuss with your current host about ways to improve security and ensure that you are always up-to-date. Your checklist to protect your online shop:

1. SSL certificate
   Ensure that your online shop uses a valid SSL certificate to establish a secure and encrypted connection between the customer’s browser and your server. An SSL certificate (Secure Sockets Layer) is a digital certificate that encrypts and authenticates the security of a website. It serves to create a secure connection between the user’s browser and the server hosting the website. Essentially, an SSL certificate encrypts sensitive data transmitted between the user’s browser and the server, meaning that even if a hacker intercepts the data traffic, the information cannot be easily read or understood. SSL certificates are primarily used for e-commerce websites, online banking, social networks, and other sites where the transfer of sensitive information such as personal data, credit card details, or passwords is required. Additionally, an SSL certificate indicates to website visitors that the site is legitimate and their data is securely transmitted. You can obtain an SSL certificate from various certificate authorities (CAs) offered by most web hosting providers. Some web hosting providers also offer free SSL certificates, while others provide paid options with advanced features and security levels. It is crucial to ensure that the SSL certificate is issued by a trusted certification authority to guarantee the security and authenticity of your website.
   
   2. Regularly updates
   Keep your e-commerce platform and all used plugins or extensions up to date to close known security vulnerabilities.
   

• Regularly visit the official website of your e-commerce platform (such as Shopware, Magento, WordPress, etc.) to look for new plugins or extensions. Many platforms have a marketplace or library where developers publish their extensions.

Sign up for newsletters or notifications on your e-commerce platform’s website. Often, platforms regularly send updates and announcements about new plugins or extensions via email.

3. Strong passwords
Use strong, unique passwords for all administrator accounts and access points to your shop, and enable two-factor authentication if possible. A strong password should meet several criteria to ensure the security of your online shop:

• Length: A strong password should be at least 12 characters long. The longer the password, the more difficult it is for an attacker to crack it.
• Complexity: A strong password should include a mix of uppercase letters, lowercase letters, numbers, and special characters. Use a variety of characters to make the password more complex.
• Uniqueness: Never use the same password for multiple accounts or websites. Instead, use a unique password for each administrator account and every access point to your shop.
• Avoid dictionary words: Do not use easily guessable words or phrases, as they are susceptible to dictionary attacks. Instead, you can use a passphrase composed of a random combination of words to increase security. An example of a strong password could be: “Tr0tz!Gehe1mSe1n@”. This password meets all the above criteria as it is long, includes a mix of uppercase letters, lowercase letters, numbers, and special characters, is unique, and does not use easily guessable dictionary words.

In addition to using a strong password, it is advisable to enable two-factor authentication when possible. Two-factor authentication adds an extra layer of security by requiring a second verification step in addition to the password, such as a one-time password sent to your mobile phone.

4. Firewall and Security software

Install a firewall and reliable security software to protect your shop from malicious attacks. There are various firewall and security software solutions available for the e-commerce sector that can help safeguard your online shop from malicious attacks. Here are some popular options:

• Web Application Firewall (WAF):
  This type of firewall is specifically designed to protect web applications by filtering and monitoring HTTP traffic between a web application and the Internet. It helps defend against attacks such as SQL injection, cross-site scripting, and file inclusion.
• Antivirus and Antimalware Software:
  Comprehensive antivirus and antimalware solutions are essential for detecting and removing malicious software that could compromise your system. These tools provide real-time protection against a wide range of threats.
• Intrusion Detection and Prevention Systems (IDPS):
  These systems monitor network traffic for suspicious activity and block potential threats. They are crucial for identifying and responding to unauthorized attempts to access or manipulate your network.
• Security Information and Event Management (SIEM):
  SIEM systems provide real-time analysis of security alerts generated by applications and network hardware. They help in detecting, analyzing, and responding to security incidents and threats.
  
  Implementing these security measures can significantly enhance the protection of your online shop against a variety of cyber threats.

5. Review Payment Processing

Ensure that the payment processing in your shop complies with applicable security standards and is regularly monitored. The Payment Card Industry Data Security Standard (PCI DSS) typically sets the security standards for payment processing in your online shop. This standard was developed to protect sensitive credit card data and ensure that it is properly processed and stored. To ensure your payment processing meets the current security standards, you can take the following steps:

• Consult the official PCI DSS website:
  The official website of the PCI Security Standards Council provides comprehensive information about PCI DSS and the requirements for secure payment processing. Here, you can find detailed information about individual requirements and the corresponding controls.
• Contact your payment provider:
  Your payment provider should be able to provide information about the security standards applicable to the payment methods they support. They can also help you verify whether your payment processing meets these standards and whether adjustments are necessary.
• Hire a security service provider:
  You can also engage an external security service provider to conduct a comprehensive security audit of your payment processing and provide recommendations for improvements. These service providers often specialize in complying with security standards like PCI DSS and can offer valuable insights.
  

By following these steps, you can ensure that your payment processing is secure and compliant with the latest security standards, thus safeguarding your customers’ data and your business’s reputation.

6. Penetration Tests and Audits
Regularly conduct penetration tests and security audits to identify and address potential vulnerabilities in your shop. Penetration tests and security audits are essential tools for detecting security gaps and weaknesses in an online shop or other IT infrastructure. Here is an explanation of what they are and why they are important:

• Penetration Testing (also known as Ethical Hacking or Pen Tests):
  Penetration testing involves controlled attacks on a computer system or application conducted by authorized security experts. The goal of a penetration test is to assess a system’s security measures by applying various attack techniques that a potential attacker might use. This process reveals vulnerabilities and security flaws that could allow an attacker to penetrate the system or compromise sensitive data.
  
• Security Audits:
  Security audits are systematic reviews of a company’s security policies, procedures, and controls. They are performed to ensure that a company’s security measures are appropriately implemented and effective. Security audits can be conducted internally or externally and often involve a comprehensive review of security policies, access controls, network configurations, software patches, and more.
  

These practices are crucial for maintaining the integrity and security of your online operations, helping to protect both your business and your customers from potential cyber threats.
