Enterprise Security Using Kerberos and LDAP (SC-360)

Please note that Oracle courses running at London training centres are subject to a 10% surcharge.

Overview

The Enterprise Security Using Kerberos course provides students with the knowledge and skills necessary to deploy Kerberos in the enterprise and to secure enterprise deployments of Lightweight Directory Access Protocol (LDAP).

Who Can Benefit
Students who can benefit from this course are individuals who want to deploy the Kerberos security, who want to deploy a secure single-sign-on solutions, and those who need secure authentication and encryption for NFS

Prerequisites

To succeed in this course, students must fully understand the material in the following courses: SA-299: Advanced System Administration for the Solaris 9 Operating System and SA-399: Network Administration for the Solaris 9 Operating System.

Delegates will learn how to
