A protocol that provides secure communication over a computer network.
Description
Secure Socket Layer (SSL) is a standard security technology for establishing an encrypted link between a server and a client. In the context of Single Sign-On (SSO) protocols, SSL plays a critical role in ensuring that user credentials and sensitive data are transmitted securely over the internet. When users log in to multiple applications using SSO, their usernames and passwords are exchanged between the identity provider and the service providers. SSL encrypts this data during transmission, preventing unauthorized access or interception by malicious actors. This secure channel is essential for maintaining user trust and data integrity in a world where cyber threats are increasingly prevalent. SSL has largely been succeeded by Transport Layer Security (TLS), which offers improved security features, but the terms are often used interchangeably. Implementing SSL/TLS not only protects login data but also enhances the overall security posture of applications, ensuring compliance with regulations such as GDPR and HIPAA.
Examples
- Online banking websites, such as Bank of America, use SSL to secure customer login and transaction data.
- E-commerce platforms like Amazon utilize SSL to protect user information during checkout and login processes.
Additional Information
- SSL certificates are issued by trusted Certificate Authorities (CAs) to verify the identity of the server.
- Using SSL is critical for any website handling sensitive information, as it helps prevent data breaches and enhances user confidence.
