Chapter 8. Remote Access and Security Protocols
OBJECTIVES
This chapter covers the following CompTIA-specified objectives for the “Protocols and Standards” section of the Network+ exam:
Define the function of the following remote access protocols and services:
Remote Access Service (RAS)
Point-to-Point Protocol (PPP)
Point-to-Point Tunneling Protocol (PPTP)
Independent Computing Architecture (ICA)
Remote access is a common feature of today's networks. An understanding of the common remote access protocols and services is a must for any network administrator.
Identify the following security protocols and describe their purpose and function:
Internet Protocol Security (IPSec)
Layer 2 Tunneling Protocol (L2TP)
Secure Sockets Layer (SSL)
Kerberos
Providing remote access facilities for a network brings with it a multitude of security concerns. To address these concerns, security protocols are available to ensure that only the intended users can access the network and the data transmitted to it.
