This week in our public vs. private series:
Communication via the Internet is made possible by data exchanges between properly functioning servers, routers, and other devices. The exchanges between your smartphone and/or computer and those devices are susceptible to eavesdropping at any point in the process. In order to prevent someone from listening in to your Internet activities computers, smartphones, servers, routers, and other devices have rules when they talk to each other, and those rules are referred to as protocols.
A protocol that is specifically designed to ensure security between servers and other devices, (often referred to as clients), is Transport Layer Security, or TLS.
Learn more about TLS in our Transport Layer Security Risk Advisory.
