What is remote access?

• Enables you to connect to your computer across
  the internet from virtually any computer, Pocket
  PC, or Smartphone.
• Mouse and Keyboard control
• Sound and printing
• Access to files and software

3
Features

• Supports multiple connections at the same time
• Works through the firewalls and supports DHCP
• Supports high screen resolutions and color depths
• Remote shutdown, restart, logoff capabilities

4
Terminal Services

• Popular method for gaining remote access to Local
  Area Networks
• Multiple remote computers can connect to terminal
  server on the LAN
• Sends only keystrokes and mouse clicks
• Receives screen updates from the host

5
Web Portals

• Secure, Web-based interface for an application
• Only need Internet Connection, Web browser
  software, and proper credentials to log on to the
  application

6
Virtual Private Networks

• VPNs are wide area networks logically defined
  over public transmission systems.
• Access to authorized users only
• Convenient and relatively inexpensive WAN
• Interoperability and security are important
  considerations when designing a VPN

Security

• Data Stream Encryption
• PAP
• Password Authentication Protocol
• CHAP
• Challenge Handshake Authentication Protocol
• RADIUS
• Remote Authentication Dial-In User Service

9
Data Stream Encryption

• 128-bit AES Encryption
• Ensures data is fully encrypted from end-to-end,
  including
• Screen Images
• File Transfers
• Keyboard and Mouse Input
• Chat Text
• Encryption key is unique for each connection

10
PAP

• Sends authentication request
• Usually user name and password
• Compares credentials with user database
• Not very secure
• Sends in clear text

11
CHAP

• Encrypts user names and passwords for
  transmission
• Requires 3 steps to complete the authentication
  process
• Server sends challenge
• Client adds password to challenge and encrypts
  the new string
• Server compares string of characters

12
CHAPAdvantages and Disadvantages

• Advantages
• Password is never transmitted
• Alone
• As clear text
• Disadvantages
• Encrypted string of characters could be captured
  and decrypted
• User name and password could be obtained

13
RADIUS

• Used with dial-up networking connections
• Caller ID Verification
• Specified phone number
• Callback Verification
• Each user has a specific phone number
• Server disconnects and calls user back at that
  number

14
Advantages of RADIUS

• Direct connection between the user and the
  dial-up server
• No information is going across the public
  Internet
• Example user IDs and passwords
• Protects against unauthorized users
