The best choice is to find or replace the systems with a Non-
Hydrochlorofluorocarbon compound. A safe replacement such as Innergen, FM-200, or other non ozone depleting agent would be used.
The goal of the Montreal Protocol is the cessation of production of ozone depleting agents.
The Montreal Protocol on Substances That Deplete the Ozone Layer is a landmark international agreement designed to protect the stratospheric ozone layer. The treaty was originally signed in 1987 and substantially amended in 1990 and 1992. The Montreal
Protocol stipulates that the production and consumption of compounds that deplete ozone in the stratosphere--chlorofluorocarbons (CFCs), halons, carbon tetrachloride, and methyl chloroform--are to be phased out by 2000 (2005 for methyl chloroform).
Scientific theory and evidence suggest that, once emitted to the atmosphere, these compounds could significantly deplete the stratospheric ozone layer that shields the planet from damaging UV-B radiation. The United Nations Environment Programme (UNEP) has prepared a Montreal Protocol Handbook that provides additional detail and explanation of the provisions.

The correct answer is C<L. If the cost to implement the safeguards is
less than the estimated loss that would occur if the corresponding
vulnerability were successfully exploited, then a legal liability exists.
The other answers are distracters.

Debbie installed an application that has installed a web server and is acting as website server for a possibly criminal organization.
A Trojan horse, or Trojan, in computing is a non-self-replicating type of malware program containing malicious code that, when executed, carries out actions determined by the nature of the Trojan, typically causing loss or theft of data, and possible system harm. The term is derived from the story of the wooden horse used to trick defenders of Troy into taking concealed warriors into their city in ancient Greece, because computer Trojans often employ a form of social engineering, presenting themselves as routine, useful, or interesting in order to persuade victims to install them on their computers without the user knowledge.
A Trojans often acts as a backdoor, contacting a controller which can then have unauthorized access to the affected computer. The Trojan and backdoors are not themselves easily detectable, but if they carry out significant computing or communications activity may cause the computer to run noticeably slowly. Malicious programs are classified as Trojans if they do not attempt to inject themselves into other files (computer virus) or otherwise propagate themselves (worm). A computer may host a Trojan via a malicious program a user is duped into executing (often an e-mail attachment disguised to be unsuspicious, e.g., a routine form to be filled in) or by drive-by download.
The following answers are incorrect:
- Network mobile code: This is incorrect because network mobile code is usually called a worm and that is malicious software that infects adjacent hosts which are unpatched against the vulnerability the worm exploits.
- Virus: A "Virus" is a generic term these days used to describe malware but isn't a specific enough term to describe what happened here?
- Logic Bomb: These are malware which, when a certain event occurs can be triggered to action. It could be a date, the creation or deletion of a file, visiting a website; basically anything a user can do can be something that triggers a logic bomb. However, this term isn't specific enough to describe what happened to Debbie's computer.
