Since we know that this particular instance of the AppMaker implements a customer-facing store that processes financial transactions, how does that influence which threat agents may be interested in attacking it?
of the whole planet and cover five percent of the Earth surface. The atomic number of iron on the periodic table is 26, belongs to the transition metal group, with an atomic mass of 55.993 amu. Its symbol, Fe, come from the Latin word Ferrum. An iron atom is consists of 26 protons, 26 electrons. Iron have four natural isotopes: Fe-54, Fe-56, Fe-57, Fe-58 and 24 radioactive isotopes. Iron ores can be found on or beneath the Earth surface. To be usable, iron ores need to have at least 30 percent iron content. Any ore that consists of 70 percent iron is considered pure, high quality and rare. The color of ores depend in its content. The most common and richest iron ore in the world are hematite and magnetite. Both of these are different form of iron oxide. Hematite (Fe2O3) is usually composed of 70 percent iron, while magnetite (Fe3O4) have about 60 percent. Iron was believed to be discovered around 5000 to 3000 B.C. Since then the making and using of iron have been developed widely and applied to many field. (Nichelson. Salem Press Encyclopedia of Science) Iron itself is not the top quality material. Pure iron does not sustain well in tough environment nor does it come with high durability, but instead wear out fast in high pressure and the oxidation caused by weather. Therefore, a combination of iron and other element, iron alloy, was used to surmount these defects in qualities. Iron’s most widely used alloy are steel, wrought iron and cast iron. Steel consists mostly of iron and other elements such as carbon, chromium, and nickel. Wrought iron is almost pure iron, with an insignificant amount of carbon. Steel contains from 0.25 to 0.15 percent carbon, while the carbon in cast iron range from 2 to 4.5 percent. These combinations aim to raise the durable and quality of the material to perform efficiently under certain condition such as under extreme high temperature and pressure, electrical resistance, or corrosion resistance. Iron and its alloys are not only the cheapest materials but they also come with high qualities, more sustainable. Today railroad, which is made mainly of steel, is tougher, not getting deformed from high friction and pressure like before. Iron is not a perfect material but the dev>GET ANSWER
