Access Controls Supervised by: Dr.Lo’ai Tawalbeh Prepared by: Abeer Saif

Introduction:  Access Controls: The security features that control how users and systems communicate and interact with one another.  Access: The flow of information between subject and object.  Subject: An active entity that requests access to an object or the data in an object. Such as a user, program, or process that accesses an object to accomplish a task.

Introduction:  Object: A passive entity that contains information. Such as: a computer, database, file, computer program, directory, or field in a table in a database, etc.

Introduction:  Access controls are extremely important because they are one of the first lines of defense used to fight against unauthorized access to systems and network resources.  Access controls give organizations the ability to control, restrict, monitor, and protect resource availability, integrity, and confidentiality.

Access Control Administration: Two Basic forms:  Centralized: One entity is responsible for overseeing access to all corporate resources. Provides a consistent and uniform method of controlling access rights.  Decentralized: Gives control of access to the people who are closer to the resources. Has no methods for consistent control, lacks proper consistency.

Centralized & Decentralized access:

Access Control methods:  Access controls can be implemented at various layers of an organization, network, and individual systems.  Three broad categories:  Administrative  Physical  Technical (aka Logical)

Access Controls ISA 2004 Internet Security & Acceleration Server 2004

ISA 2004 overview:

 ISA Server 2004 main roles:  Firewall.  Packet inspection & filtering.  Stateful inspection & filtering.  Application layer inspection & filtering.  VPN server.  Unified firewall & VPN Server.  Proxy and Caching server.  Forward cache.  Backward cache.

ISA 2004 overview:  ISA Server 2004 as a VPN server:  VPN (Virtual Private Network): is a secure network connection created through a public network such as the Internet.  Types of VPN connections:  VPN clients.  Site-Site VPN.  Quarantine Control.

ISA 2004 overview:  Why use VPN connections:  Availability.  Cost.  Internet Protocol security (IPSec): A set of industry- standard, cryptography based protection services and protocols. IPSec protects all protocols in the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite and Internet communications.

ISA 2004 overview:  Protocols supported by ISA Server 2004:  Point-Point tunneling protocol (PPTP):  Uses Microsoft’s encryption (MPPE).  Less Complex to set than IPsec.  Layer two tunneling protocol (L2TP):  More secure than PPTP.  IPsec concepts more complex.
