In computing, a firewall is a software or firmware that enforces a set of rules about what data packets will be allowed to enter or leave a network. Firewalls are incorporated into a wide variety of networked devices to filter traffic and lower the risk that malicious packets traveling over the public internet can impact the security of a private network. Firewalls may also be purchased as stand-alone software applications.

E-commerce security is a set of protocols that safely guide e-commerce transactions. Stringent security requirements must be in place to protect companies from threats like credit card fraud, or they risk jeopardizing revenue and customer trust, due to the inability to guarantee safe credit card processing.

E-commerce security risks can be accidental, intentional or caused by a human error. The most prevalent cybersecurity threats include phishing attacks, hacking, credit card fraud, data errors or unprotected online services. For an e-commerce business, poor security management is the greatest cause of risk for online retailers.
