• Data that has traveled across the network cannot be trusted; it can be intercepted intentionally or unintentionally and used for unauthorized purposes
  • Secure Sockets Layer (SSL) is a widely used application layer cryptographic protocol that secures communication over the internet through:
    – Encryption
    Protects data in transmission from intrusions with encrypt and decrypt methods
    – Authentication
    Verifies sender’s identity by providing certificates and securing connections between client and server
    – Digital Certificates
    Validates the certificate issued by CA ensuring the integrity of data in transmission
