![]() ![]() Authentication: the client can validate the identity of the server to make sure the connection is established with the correct server.Ĭertificate Authorities (CAs) are an integral part of a secure client server communication and they are predefined in the trust store of each operating system.Integrity: the data can't be altered without detection.Confidentiality: TLS encrypts data before sending it over the network, which means it can't be read by an intermediary.And TLS performs a handshake using public key cryptography and, when complete, creates a secure connection.Īn HTTPS connection is considered secure because of three properties: ![]() HTTPS is essentially HTTP layered on top of another protocol known as Transport Layer Security (TLS). The time has long passed since it was reasonable to use cleartext HTTP alone and it's usually trivial to secure HTTP connections using HTTPS. In this chapter we discuss potential vulnerabilities, testing techniques, and best practices concerning the network communication between mobile apps and their endpoints. Consequently, network-based attacks (such as packet sniffing and man-in-the-middle-attacks) are a problem. Practically every network-connected mobile app uses the Hypertext Transfer Protocol (HTTP) or HTTP over Transport Layer Security (TLS), HTTPS, to send and receive data to and from remote endpoints.
