SSL commonly refers to the two cryptographic protocols in computer network security – transport layer security (TLS) and its predecessor, security sockets layer (SSL). The purpose of SSL is to provide secure communications over a network, and SSL-encrypted data now accounts for more than 80 percent of all internet traffic, according to Google. Many malware authors now hide their malicious code inside SSL-encrypted traffic. Yet many organizations don’t scan SSL traffic, because it is compute intensive do to so, requiring considerable hardware upgrades.
