Summary
This chapter focused on comprehensive security solutions. The two broad topics of this chapter examined:
- Network protocols
- Applications and services
Modern networks are built on the TCP/IP protocol stack. As a CASP+, you should have a good understanding of how TCP/IP works and know the purpose and weaknesses of the primary protocols such as IPv4, IPv6, TCP, UDP, and ICMP.
You should also have a grasp of network flow analysis. You must also understand the importance of securing routing protocols and be familiar with controls put in place to improve transport security, trucking security, and route protection.
Applications and services are also of importance to a CASP+. You must know how to secure DNS, understand the importance of securing zone transfers, and know how to configure LDAP.
Finally, there is authentication along with authentication protocols such as PAP, CHAP, and EAP. This critical component is used as a first line of defense to keep hackers off your network. Systems...
