Fail security

FMVEA extends this approach with a security analysis. Components are not only examined for failure modes, but also for threat modes. While a failure mode describes how a system quality attribute [10] fads, a threat mode describes how a security attribute of the components fails. It is the maimer by which a occurred threat is observed. Causes for failing security attributes are vulnerabilities. In order to estimate the frequency of threat modes, potential attackers (threat agents) are identified. The probability of a threat mode is determined based on the threat agent and the vulnerability. The results of a FMVEA are the failure and threat modes of a system, and their causes and consequences. In addition, failure and threat modes are evaluated in terms of probability and severity. We refer the reader to [3] for a more detailed description of FMVEA. [Pg.283]

In industrial premises it is also important that the target level values are guaranteed and that the ventilation system operation can be secured so that the process is not violated because of the ventilation. There are many examples where important fans have failed or important components have corroded, causing extensive losses for the company. In many cases the whole production plant has stopped. [Pg.406]

Organizations thrive or fail on trust. Trust is a precious commodity impossible to quantitate on a bottom line, fragile, and, when damaged, difficult to repair. When there is trust in an organization, resources and information are shared freely and efficiently. Ironically, during the "efficiency drives" of the recent past, the employment security that once was the cornerstone of trust in scientific organizations was eliminated. The analytical manager must therefore establish trust within his operation despite the uncertain employment environment. [Pg.41]

Tramadol is a reasonable option for patients with contraindications to NSAIDs or failure to respond to other oral therapies. For the treatment of hip or knee OA, tramadol is as effective as NSAIDs. The addition of tramadol to NSAIDs or acetaminophen may augment the analgesic effects of a failing regimen, thereby securing sufficient pain relief in some patients. Moreover, concomitant tramadol may permit the use of lower NSAID doses. [Pg.888]

Partial correctness is analogous to weak equivalence in that it is a sort of fail-safe condition. If A(a) = FALSE the input criterion is invalid and a presumably never occurs as input and so we make no claims as to the behavior of program (P,I) with "bad" input. If (P,I,a) does not halt there is no output and this is also regarded as a don t-care situation. There are fairly realistic situations where we would be perfectly satisfied with this sort of "correctness" -for example, in data security or protection systems. We presume - or have enpirical evidence - that the system does not fail often or catastrophically and wish to know that when it is working and output is given (of whatever kind, for the output could be just internal transfer of data) then the result is "good" or, more likely, nothing "bad" happens. [Pg.45]

As can be seen in Fig. 5.44 as well, flames in gas heaters have a similar emission spectrum. Besides the UV surveillance ionization electrodes are often used in gas burners. The method is cheap and secure but it disturbs the combustion process since the electrode has to be placed close to the flames. New developments in gas heaters focus on catalytic combustion on a metal mesh. There, an ionization electrode would fail due to the lack of a flame. However, the characteristic UV emission is still present... [Pg.172]

It is generally agreed that worldwide petroleum supply will eventually reach its productive limit, peak, and begin a long term decline. One of the alternatives is the Nation s untapped oil shale as a strategically located, long-term source of reliable, affordable, and secure oil. The extent of U.S. oil shale resources, which amounts to more than 2 trillion barrels, has been known for a century. In 1912, the President established the Naval Petroleum and Oil Shale Reserves. There have been several commercial attempts to produce oil from oil shale, but these have failed because of the lower cost of petroleum at the time. With future declines in petroleum production, market forces are expected to improve the economic viability of oil shale. [Pg.44]

Fire protection system impairment occurs when a fire alarm or supervisory system is shut-off, damaged, fails, or is otherwise taken out-of-service completely or in part. These out-of-service conditions are called impairments. While process monitoring, control, safety, and security-entry systems also provide protective functions, this element of the fire prevention program is only concerned with impairments to fire protection systems and equipment. An essential element of the fire prevention program is a procedure for fire protection impairment handling. [Pg.349]

Assets are classified as current, fixed, or intangibles. Current assets include cash, cash equivalents, marketable securities, accounts receivable, inventories, and prepaid expenses. Cash and cash equivalents are those items that can be easily converted to cash. Marketable securities are securities that a company holds that also may be converted to cash. Accounts receivable are the amounts due a company from customers from material that has been delivered but has not been collected as yet. Customers are given 30, 60, or 90 days in which to pay however, some customers fail to pay bills on time or may not be able to pay at all. An allowance is made for doubtful accounts. The amount is deducted from the accounts receivables. Inventories include the cost of raw materials, goods in process, and product on hand. Prepaid expenses include insurance premiums paid, charges for leased equipment, and charges for advertising that are paid prior to the receipt of the benefit from these items. The sum of all the above items is the total current assets. The term current refers to the fact that these assets are easily converted within a year, or more hkely in a shorter time, say, 90 days. [Pg.9]

Sack, Kevin. Gunman Slays 9 at Brokerages in Atlanta. The New York Times, July 30, 1999, p. A1. Reports on a killing rampage by failed Atlanta securities day-trader Mark O. Barton who killed nine people, wounded 12, and finally killed himself when cornered by police. [Pg.178]
