Description: Prevention methods in e-commerce security are strategies and techniques designed to protect online transactions and sensitive user information. These methods aim to anticipate and mitigate risks associated with fraud, identity theft, and other types of cyberattacks. Implementing preventive measures is crucial for building consumer trust, as customers are increasingly aware of the importance of security in their online purchases. Key features of these methods include user authentication, data encryption, the use of firewalls and intrusion detection systems, as well as user education on safe practices. The relevance of these methods lies in the fact that as e-commerce continues to grow, so do security threats, making it essential for businesses to adopt a proactive approach to protect both their assets and customer information. In summary, prevention methods are fundamental to ensuring a safe and reliable online shopping environment, which in turn fosters e-commerce growth and customer satisfaction.
