A local area network (LAN) is a critical component of a modern data network. A LAN is comprised of one or more computers, a communication protocol, a network topology, and cabling or a wireless network to connect the systems.

No system or architecture will ever be completely secure; there will always be a certain level of risk.

Security Models of Control Security models of control are used to determine how security will be implemented, what subjects can access the system, and what objects they will have access to. Simply stated, they are a way to formalize security policy.

Although a robust architecture is a good start, real security requires that you have security mechanisms in place to control processes and applications. Some good security mechanisms are described in the following sections.

Computer System Architecture At the core of every computer system is the CPU and hardware that make it run.

  Penetration testing is a series of activities undertaken to identify and exploit security vulnerabilities.

Single sign-on is an attempt to address a problem that is common for all users and administrators.

Data access controls are established to control how subjects can access data, what they can access with it, and what they can do with it once accessed. Three primary types of access control are discussed in this section.   [bs_icon name=”glyphicon glyphicon-chevron-right”]   Mandatory Access Control (MAC)

The two law systems that form the basis of legal systems in most countries are:

An IDS is designed to function as an access-control monitor. It can monitor network or host activity and record which users attempt to access specific network resources.
