Remote Access Flashcards
4.3.2
Types of remote access
Service specific
Remote control
Remote node operation
Screen scraping
Service Specific
Give users the ability to remotely connect to and manipulate or interact with a single service
Remote Control
grants a remote user the ability to fully control another system that is physically distant
Remote Node Operation
Remote client connecting directly to a LAN
Screen Scraping
Remote control, remote access or remote desktop services
Technology that allows an automated tool to interact with human interface
Remote Access Security Management
Strong Authentication System
Limit Remote access to only those who need it
Implement encryption across transmission link via VPN, SSL, TLS, SSH, or IPSec
Virtual Private Network (VPN)
communication tunnel that establishes a secure point to point connection over an untrusted network.
Common VPN protocols
Point to Point Tunneling (PPTP): data link layer used on IP networks
Layer 2 Tunneling Protocol (LPTP): Data Link layer used on any LAN protocol
IPSec: Network Layer used on IP networks
Point to Point Tunneling Protocol
Encapsulates Point to Point Protocol (PPP)traffic at the data link layer and is used on IP networks
Supported PPTP Protocols
Microsoft Challenge Handshake Authentication Protocol (MS-CHAP)
CHAP
PAP
EAP
Shiva Password Authentication Protocol (SPAP)
Layer 2 Tunneling Protocol (L2TP)
derived to create a point to point tunnel to connect disparate networks. Doesn’t employ encryption or strong authentication but in conjunction with IPSec it is possible.
