Topics:
Introducing Cryptography
- Describe common terms and techniques used in cryptography
- Understand the role and usage of cryptography in securing computer networks
- Discuss the architecture of the Secured Sockets Layer (SSH) protocol
Reviewing NTP
- Discuss the need for time synchronization in a networked environment
- Configure client system to synchronize time with a network server
- Deploy a Network Time Protocol (NTP) server which client systems can query
- Configure access restrictions on NTP clients and servers
Introducing Kerberos
- Discuss typical security and convenience limitations
- Describe the benefits afforded by the use of Kerberos in the enterprise
- Explain the conceptual operation of Kerberos
Examining Kerberos
- Describe the configuration files and applications that comprise Kerberos

- Configure client systems to authenticate using Kerberos
Using Kerberos
- Describe the process which users authenticate as Kerberos principals
- Discuss the tools available to change passwords for Kerberos principals
- Explain how Kerberos principals can grant password-less accounts
Administering Kerberos
- Configure Kerberos keytabs
- Establish Kerberos principal password policies
- Configure PAM to provide Solaris users with single sign-on access
Implementing Cross-Realm Authentication
- Discuss reasons for using one Kerberos realm, or multiple Kerberos realms
- Describe the cross-realm authentication trust arrangements
- Configure direct and hierarchical cross-realm authentication relationships
Integrating Kerberos Implementations
- Discuss interoperability concerns between standards-compliant and nonstandard Kerberos implementations
- Describe Kerberos topologies used when integrating Microsoft Kerberos
- Configure Microsoft Kerberos as a hierarchical sub-realm
Reviewing LDAP
- Describe the structure of a Lightweight Directory Access Protocol
- Discuss common uses of LDAP
- Understand common LDAP terminology
Configuring LDAP Security
- Discuss methods of authenticating access to LDAP directories
- Describe tools used to secure LDAP transactions
- Describe tools used to secure access to specific entries within the LDAP directory
Integrating Kerberos and LDAP
- Contrast the benefits afforded by use of Kerberos with those of LDAP
- Describe methods in which Kerberos and LDAP can be used simultaneously
- Detail the security advantages and disadvantages of using LDAP with Kerberos
- Detail the security advantages and disadvantages using Kerberos on top of LDAP
