Bezpiecze\u0144stwo system\u00f3w IT<\/H1>"},"content":{"rendered":"

O ile 20 lat temu komputery<\/strong> by\u0142y przede wszystkim narz\u0119dziem pomocnym przy wsparciu pojedynczych funkcji w firmie (np. gospodarka materia\u0142owa), tak dzisiaj systemy informatyczne <\/strong>s\u0105 w stanie wspiera\u0107 praktycznie wszystkie procesy i funkcje wewn\u0119trzne w firmie.<\/p>\n

Jest wiele korzy\u015bci wynikaj\u0105cych z zastosowania informatycznych system\u00f3w komputerowych<\/strong> kt\u00f3re sprawiaj\u0105, \u017ce stale pojawiaj\u0105 si\u0119 nowe obszary ich rozwoju. Jednocze\u015bnie dzisiaj ma\u0142o kt\u00f3ry przedsi\u0119biorca jest w stanie wyobrazi\u0107 sobie prowadzenie dzia\u0142alno\u015bci biznesowej bez mo\u017cliwo\u015bci wykorzystania komunikacji mailowej<\/strong> (jest jednym z potencjalnych zagro\u017ce\u0144 zewn\u0119trznych).<\/p>\n

W\u015br\u00f3d czynnik\u00f3w mog\u0105cych mie\u0107 niebezpieczny wp\u0142yw na systemy informatyczne w firmie mo\u017cna wymieni\u0107:
\n – Systemy IT w firmie staj\u0105 si\u0119 coraz bardziej kompleksowe i obejmuj\u0105 coraz wi\u0119ksz\u0105 liczb\u0119 obszar\u00f3w funkcjonalnych<\/strong>. Wi\u0119kszo\u015b\u0107 z element\u00f3w tych system\u00f3w jest ze sob\u0105 zintegrowana i tym samym wymagania odno\u015bnie ich bezpiecze\u0144stwa staj\u0105 si\u0119 coraz wy\u017csze i jednocze\u015bnie coraz bardziej z\u0142o\u017cone,
\n – Du\u017ca dynamika proces\u00f3w wewn\u0119trznych<\/strong> i zale\u017cno\u015b\u0107 od system\u00f3w informatycznych w firmie s\u0105 czynnikami, kt\u00f3re nie u\u0142atwiaj\u0105 procesu utrzymania bezpiecze\u0144stwa wszystkich element\u00f3w organizacji,
\n – Rosn\u0105ca otwarto\u015b\u0107 organizacji na zewn\u0105trz<\/strong>, przejawiaj\u0105ca si\u0119 w wielu obszarach funkcjonowania firmy (np. elektroniczna wymiana danych (EDI) mi\u0119dzy dwoma systemami informatycznymi dw\u00f3ch firm, integracja firmy z systemami i platformami sprzeda\u017cowymi takimi jak Allegro, Ebay, Amazon, elektroniczne p\u0142atno\u015bci realizowane mi\u0119dzy firm\u0105 i bankiem lub instytucj\u0105 finansow\u0105 systemy np. PayPal, PayU),
\n– Wzrost liczby haker\u00f3w<\/strong>, spamer\u00f3w<\/strong> oraz innych u\u017cytkownik\u00f3w internetu, kt\u00f3rzy stale zadaj\u0105 sobie pytanie „jak mog\u0119 wykorzysta\u0107 systemy informatyczne firm i innych u\u017cytkownik\u00f3w internetu do moich w\u0142asnych cel\u00f3w?”.<\/p>\n

Bior\u0105c pod uwag\u0119 powy\u017csze kwestie, nie ma si\u0119 co dziwi\u0107, \u017ce stale ro\u015bnie znaczenie bezpiecze\u0144stwa system\u00f3w informatycznych<\/strong>.<\/p>\n

Hakerzy<\/strong>, oszu\u015bci<\/strong> i sabota\u017cy\u015bci<\/strong> nieustannie szukaj\u0105 nowych sposob\u00f3w, aby systemy informatyczne wystawione na zewn\u0105trz wykorzysta\u0107 do swoich cel\u00f3w. Ka\u017cdego dnia pojawiaj\u0105 si\u0119 nowe wirusy<\/strong>, robaki<\/strong>, fa\u0142szywe maile<\/strong> oraz programy szpiegowskie<\/strong> (Trojany). W praktyce ka\u017cdy przedsi\u0119biorca codziennie musi usuwa\u0107 dziesi\u0105tki lub nawet setki maili, kt\u00f3re niepo\u017c\u0105dane docieraj\u0105 do jego skrzynki pocztowej<\/strong> i wiele z nich kryje za sob\u0105 r\u00f3\u017cne potencjalne zagro\u017cenia.<\/p>\n

Firmy zajmuj\u0105ce si\u0119 bezpiecze\u0144stwem internetu ka\u017cdego dnia notuj\u0105 tysi\u0105ce z\u0142o\u015bliwych atak\u00f3w<\/strong> na komputery wystawione w sieci internetowej i niestety liczba ta stale ro\u015bnie.<\/p>\n

Planuj\u0105c koncepcj\u0119 bezpiecznego systemu informatycznego<\/strong> warto podzieli\u0107 wszystkie wyst\u0119puj\u0105ce w firmie informacje wg poziomu ich wa\u017cno\u015bci i poufno\u015bci, w szczeg\u00f3lno\u015bci:
\n – \u015bci\u015ble tajne<\/strong> – dost\u0119p do informacji mog\u0105 mie\u0107 tylko wybrane osoby, pracownicy kierownictwa\/zarz\u0105du firmy,
\n – poufne<\/strong> – dost\u0119p do informacji mo\u017ce mie\u0107 wybrany kr\u0105g os\u00f3b, pracownik\u00f3w kierownictwa i specjalist\u00f3w firmy,
\n – wewn\u0119trzne<\/strong> – dost\u0119p do informacji mog\u0105 mie\u0107 tylko pracownicy firmy,
\n – publiczne<\/strong> – dost\u0119p do informacji mo\u017ce mie\u0107 ka\u017cdy potencjalny jej u\u017cytkownik (zar\u00f3wno b\u0119d\u0105cy pracownikiem firmy, jak r\u00f3wnie\u017c potencjalnym klientem, urz\u0119dnikiem czy inna osoba zainteresowana firm\u0105 i jej produktami). <\/p>\n

W temacie bezpiecze\u0144stwa informatycznego mo\u017cna r\u00f3wnie\u017c skorzysta\u0107 z auditu bezpiecze\u0144stwa IT<\/strong>, kt\u00f3rego celem jest stwierdzenie w kt\u00f3rych obszarach stan bezpiecze\u0144stwa IT w firmie odbiega od stanu po\u017c\u0105danego<\/strong> (gwarantuj\u0105cego bezpiecze\u0144stwo systemu IT). Audit bezpiecze\u0144stwa IT jest szczeg\u00f3lnie polecany w ma\u0142ych firmach<\/strong>, kt\u00f3re nie maj\u0105 rozbudowanych struktur zarz\u0105dzania IT.<\/p>\n","protected":false},"excerpt":{"rendered":"
