1. Learning the Basics

2. What is a Virtual Directory?
 A virtual directory is a software layer that
delivers a single access point for efficient
identity management applications as well as
service platforms

3. Functions of VDS
 works as a high-performance, lightweight
abstraction layer residing between client
applications and contrasting types of
identity-data directory repositories e.g.:
standard and proprietary directories, web
services, applications and databases

4. More…
 receives queries and directs them to the
appropriate data sources by abstracting and
virtualizing data
 consolidates data stored in a distributed
environment

5. Advantages for your Company
 Enable faster deployment because users do not need to
add and sync additional application-specific data
sources
 Deliver high availability of data sources
 LDAP Proxy
 LDAP Firewall

6. LDAP PROXY
 A solution which provides enhanced
security, scalability, and directory
access control to an existing directory
infrastructure

7. LDAP FIREWALL
 A prevention program which
provides added security and allows
companies to restrict certain parts of
their directory infrastructure and
block unwanted users
 Prevents DoS

8. Denial-of-Service (DoS) Attacks
 Attempt to prevent legitimate users from accessing
information or services
 Most obvious type happens when an attacker “floods”
a network with information
 A server can only process a certain number of requests
at once, so if an attacker overloads the server with
requests, it ‘s incapable of processing your request
