• Describe how packets/fragments are forwarded in the right direction at each layer in the network stack.
• Know when confidentiality, message integrity, and signatures are necessary.
• Effectively use basic cryptography tools — hashes, block ciphers, stream ciphers, and digital signatures — and identify common weaknesses in cryptography schemes.
