-    "description": "Single Sign-On (SSO) is an authentication method that allows users to access multiple applications or systems with one set of login credentials. It enables users to log in once and gain access to various connected systems without re-entering credentials. SSO enhances user experience by reducing password fatigue, streamlines access management for IT departments, and can improve security by centralizing authentication controls. It typically uses protocols like SAML, OAuth, or OpenID Connect to securely share authentication information across different domains. While SSO offers convenience and can strengthen security when implemented correctly, it also presents a single point of failure if compromised, making robust security measures for the SSO system critical.\n\nLearn more from the following resources:",
+    "description": "Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are cryptographic protocols used to provide security in internet communications. These protocols encrypt the data that is transmitted over the web, so anyone who tries to intercept packets will not be able to interpret the data. One difference that is important to know is that SSL is now deprecated due to security flaws, and most modern web browsers no longer support it. But TLS is still secure and widely supported, so preferably use TLS.\n\nLearn more from the following resources:",
