How To Boost Ecommerce Security for Your Online Store (2024)

What is ecommerce security?

Ecommerce security refers to the measures and practices put in place to protect online stores and their customers from cyber threats and attacks. This includes ensuring the privacy, integrity, and authentication of data, as well as preventing non-repudiation.

Elements of ecommerce security


Privacy in ecommerce security involves protecting the sensitive personal and financial information of customers from unauthorized access or disclosure.


Integrity ensures that data remains accurate and consistent throughout its lifecycle, and is not tampered with or altered by unauthorized parties.


Authentication verifies the identity of users and ensures that only authorized individuals have access to the online store’s resources and data.


Non-repudiation prevents individuals from denying their actions in a transaction, providing a level of accountability and trust in ecommerce transactions.

Common ecommerce security threats

Brute force attacks

Brute force attacks involve attempting to guess a user’s password by systematically trying all possible combinations until the correct one is found.

DDoS (distributed denial of service) attacks

DDoS attacks overwhelm a website with a flood of traffic, causing it to become slow or unavailable to legitimate users.

Data breaches

Data breaches involve the unauthorized access and theft of sensitive customer information, such as credit card numbers and personal details.

Payment fraud

Payment fraud occurs when criminals use stolen credit card information to make unauthorized purchases on ecommerce websites.

Malware and ransomware

Malware and ransomware are malicious software that can infect ecommerce websites and hold them hostage or steal sensitive data.


Phishing involves tricking individuals into revealing sensitive information, such as login credentials or financial details, by posing as a legitimate entity.

Supply chain attacks

Supply chain attacks target the weak links in a website’s supply chain, such as third-party vendors or software providers, to gain access to the ecommerce store’s systems.

API attacks

API attacks exploit vulnerabilities in the application programming interfaces used by ecommerce websites to access and share data.

Best practices for ecommerce security

Implement multilayer security

Utilize a combination of security measures, such as firewalls, encryption, and intrusion detection systems, to create a multilayered defense against cyber threats.

Make use of SSL certificates

Secure Sockets Layer (SSL) certificates encrypt data transmitted between the customer’s browser and the ecommerce website, protecting it from interception by attackers.

Guard against cross-site scripting (XSS)

Prevent cross-site scripting attacks by validating and sanitizing user input, and implementing security controls to protect against malicious code injection.

Comply with General Data Protection Regulation (GDPR) guidelines

Ensure that your ecommerce store complies with GDPR regulations regarding the collection, processing, and storage of personal data of European Union citizens.

Regularly update and patch computer systems

Keep your ecommerce platform, plugins, and software up to date with the latest security patches and updates to fix known vulnerabilities.

Use anti-malware software

Install and regularly update anti-malware and antivirus software to detect and remove malicious software from your ecommerce website.

Enhance login security

Implement strong password policies, multi-factor authentication, and login attempt monitoring to protect against unauthorized access to customer accounts.

Use trusted payment services

Utilize reputable and secure payment gateways and processors to handle customer transactions and protect sensitive financial information.
