Internet

Law 6. Computer security depends on the reliability of the administrator is true. It is also true that administrators should be very small, and each has its own responsibilities and opportunities of access. Well, quite a flagrant violation is when a manager or department heads have administrative rights. An administrator should be the 'unwilling' to the organization. That is, a person must be selected – the observer (it just might be the boss at any level) who has the right to see and observe all the changes, but just to see (the right to change it does not). The administrator of the same direction have the right to make changes in this direction (such as a database administrator), but he changed nothing organizationally impossible.

For example, take a person at work – you need to make it into the system. As it usually happens? (I think you know) How should it be? Otlel personnel must fill out a form for new hires. This form is submitted employee's immediate supervisor, which he defines (placing a tick) which services and services (tazhe elektoronnaya mail and the Internet), the employee should have access. And only on the basis of this form (it can be electronically and on paper), the administrator enters the human system. More info: Justin Mateen. Similarly, should occur very quickly and automatically lock a user account (it dlokirovka rather than removal – remove – this is also an error security) for his dismissal. Law 7. Security of encrypted data depends on how protected decryption key here, and add nothing special, everything is clear from the title.

Biotenaol

Bioetanol has manifolds uses: for example, it is used like see-fuel in gasoline motors, since it allows to one better combustion when increasing the fuel grade of the mixture, like fuel for heating in chimneys and boilers or even like potenciador of fuels of greater yield. The ecological advantages of bioetanol are many and substantially contribute to reduce to the gas discharges with greenhouse effect. For example, when replacing a liter of gasoline by bioetanol is reduced in a 60% the emissions of these gases. A single hectare of beet absorbs the equivalent to the annual emissions in CO? of 10 cars. Also, the biological fuel consumption as bioetanol replaces other exogenous and problematic energies, like the fossil and the nuclear one. Also the residues produced in the biological fuel elaboration are much less injurious for the environment and constitute a smaller risk of biological contamination u organic. So that the biological fuel use, even on small scale in the homes, along with the small echo-gestures of the citizens, contributes significantly to the protection of the environment. The heating of the homes is the domestic action that has major environmental impact. In this sense, many ecological governments and organizations recommend a more rational consumption of energy in the homes by means of the use of less polluting electric home appliances, like ecological chimneys or chimneys of bioetanol, so that, as he already said to the philosopher Discardings in century XVII, we pruned to find a practice by means of which, knowing the force and the actions the air, the stars, skies and of all the other bodies that surround to us, we pruned to use them in all the uses to that they are own () mainly by the conservation of the health, that is, without a doubt, the first good and the foundation of the other goods of this life.
