Security Protocols Flashcards
A standard that provides cryptographic security for electronic messaging
Secure/Multipurpose Internet Mail Extensions(S/MIME)
Cryptographic protocols that provide secure Internet communications for
web browsing, instant messaging, email, VoIP, and many other services
Secure Socket Layer (SSL) and Transport Layer Security (TLS)
A protocol is tricked into using a lower quality version of itself instead of
a higher quality version
Downgrade Attack
A protocol that can create a secure channel between two computers or
network devices to enable one device to control the other device
Secure Shell (SSH)
A secure connection between two or more computers or device that are
not on the same private network
Virtual Private Networks
A protocol that encapsulates PPP packets and ultimately sends data as
encrypted traffic
Point-to-Point Tunneling Protocol (PPTP)
A connection between two or more computers or device that are not on
the same private network
Layer 2 Tunneling Protocol (L2TP)
A TCP/IP protocol that authenticates and encrypts IP packets and
effectively securing communications between computers and devices
using this protocol
IPSec
Method used by IPSec to create a secure tunnel by encrypting the
connection between authenticated peers
Internet Key Exchange (IKE)
Protocol used in IPSec that provides integrity and authentication
Authentication Header (AH)
Provides integrity, confidentiality, and authenticity of packets by
encapsulating and encrypting them
Encapsulating Security Payload (ESP)
Host-to-host transport mode only uses encryption of the payload
of an IP packet but not its header
Transport Mode
A network tunnel is created which encrypts the entire IP packet
(payload and header
Tunnel Mode
