overloaded as to cause a crash of the system. Dual Homing - Having concurrent connectivity to more than one network from a computer or network device. Examples include: Being logged into the Corporate network via a local Ethernet connection, and dialing into AOL or other internet service provider (ISP). e-Commerce - Electronic transaction, performed over the Internet – usually via the World Wide Web – in which the parties to the transaction agree, confirm, and initiate both payment and goods transfer. Firewall - Security devices used to restrict access in communication networks. They prevent computer access between networks (i.e.: from the Internet to your corporate network), and only allow access to services, which are expressly registered. Fix - An operational expedient that may be necessary if there is an urgent need to amend or repair data, or solve a software bug problem. Hacker - An individual whose primary aim in life is to penetrate the security defenses of large, sophisticated, computer systems. A truly skilled hacker can penetrate a system right to the core, and withdraw again, without leaving a trace of the activity. Incursion - A penetration of the system by an unauthorized source. Similar to an Intrusion, the primary difference is that Incursions are classed as ‘hostile’. Integrity - Assurance that the information is authentic and complete. Ensuring that information can be relied upon to be sufficiently accurate for its purpose. The term integrity is used frequently when considering Information Security as it represents one of the primary indicators of security (or lack of it). The integrity of data is not only whether the data is ‘correct’, but also whether it can be trusted and relied upon. For example, making copies (say by e-mailing a file) of a sensitive document, threatens the integrity of information. By making one or more copies, the data is then at risk of change or modification. Internet - A publicly accessible Wide Area Network that can be employed for communication between computers. Intranet - A Local Area Network within an organization, which is designed to look like, and work in the same way as, the Internet. Intranets are essentially private networks, and are not accessible to the public. Procedure: PRC-2004-0803 Revision: 0.2.6 Effective Date: May 24, 2005 Page 11 of 15

SECURITY PROCEDURE Firewalls IV. Definitions (con’t) Intrusion - The IT equivalent of trespassing. An uninvited and unwelcome entry into a system by an unauthorized source. While incursions are always seen as hostile, intrusions may be innocent. IP Address - The IP address or ‘Internet Protocol’ is the numeric address that guides all Internet traffic, such as e-mail and Web traffic, to its destination. Lab - A Lab is any non-production environment, intended specifically for developing, demonstrating, training and/or testing of a product.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
