Secure communications refer to methods of exchanging information that protect the content from unauthorized access or interception. This can involve various techniques, such as encryption, which transforms readable data into a coded format that only authorized parties can decode. Secure communications are essential for protecting sensitive information, such as personal data, financial transactions, and confidential business communications. Common tools for secure communications include VPNs (Virtual Private Networks), which create a private network over the internet, and SSL/TLS (Secure Sockets Layer/Transport Layer Security), which encrypts data transmitted between web browsers and servers. These technologies help ensure that messages remain private and secure from potential threats, such as hackers or eavesdroppers.
