Sztuczna Inteligencja

Jak AI chroni serwery Linux VPS w firmach?

slawek•

Według raportu IBM Cost of a Data Breach 2023, średni koszt naruszenia bezpieczeństwa danych dla małych i średnich firm przekroczył 3,3 miliona dolarów — i po raz pierwszy w historii badania większość incydentów dotyczyła infrastruktury chmurowej i serwerów VPS. To zmienia fundamentalne założenie, które przez lata uspokajało właścicieli mniejszych firm: że hakerzy celują wyłącznie w wielkie korporacje. Połączenie serwerów Linux VPS z narzędziami opartymi na sztucznej inteligencji przestaje być luksusem dla działu IT dużej firmy, a staje się realną koniecznością operacyjną. Dlaczego tradycyjne metody ochrony serwerów zawodzą? Klasyczne systemy bezpieczeństwa opierają się na z góry zdefiniowanych regułach — blokują konkretny adres IP po określonej liczbie nieudanych logowań lub oznaczają plik, jeśli pasuje do wcześniej zidentyfikowanego wzorca złośliwego oprogramowania. Taki model działa sprawnie wyłącznie przeciwko zagrożeniom, które już raz ktoś opisał i skatalogował. Problem polega na tym, że współczesne cyberataki coraz rzadziej przypominają te z przeszłości. Złośliwe oprogramowanie mutuje, wektory ataku ewoluują, a napastnicy aktywnie testują granice znanych sygnatur przed każdą operacją. Firma CrowdStrike w raporcie z 2023 roku odnotowała, że czas potrzebny atakującemu do przemieszczenia się wewnątrz zainfekowanej sieci skrócił się do średnio 79 minut — znacznie poniżej czasu reakcji człowieka analizującego logi. Reguły statyczne mają jeszcze jeden strukturalny problem:…

Wideo tygodnia z teleskopu Hubble
Theis video features NGC 4654, an intermediate spiral galaxy in the constellation Virgo (the Maiden). It is situated 72 million light-years from Earth in the Virgo Cluster, a particularly massive and populous galaxy cluster.

Zoom video: MACS J0553.4-3342
In new images from the NASA/ESA/CSA James Webb Space Telescope to celebrate its fourth science anniversary, a familiar galaxy transforms into something far richer, and far more complex, than ever seen before. Webb’s unprecedented sensitivity across near- and mid-infrared wavelengths cuts through the thick lanes of dust that obscure Centaurus A’s centre in visible light, showing a densely packed tapestry of individual stars and an active, everchanging galaxy. These images mark four years of better-than-anticipated performance and successful science operations for the most powerful space telescope in history. This video shows three new views of Centaurus A as seen by Webb. More information and download options: http://esawebb.org/videos/weic2616c/ Credit: NASA, ESA, CSA, STScI, A. Pagan (STScI), J.

Transition video: Centaurus A
This video takes the viewer on a journey through space to reveal a new image from the NASA/ESA/CSA James Webb Space Telescope's Mid-Infrared Instrument (MIRI) to celebrate its fourth anniversary of science. The video reveals the nearby galaxy Centaurus A, exposing the dusty structures and hidden activity that shape this unusual system. Webb’s infrared vision pierces thick lanes of dust that obscure much of the galaxy in visible light, unveiling intricate filaments, loops, and glowing clouds of warm dust stretching across its centre. At the heart of the galaxy, an actively feeding supermassive black hole shines brightly, surrounded by complex structures sculpted by a past galactic collision and ongoing activity.

Space Sparks Episode 30: Webb’s fourth year in images
In this ESA/Webb Picture of the Month from the NASA/ESA/CSA we are taken on a visit to a building site of significant scale. The project is a galaxy cluster named MACS J0553.4-3342, located in the constellation Columba (the Dove). We are seeing MACS J0553.4-3342 as it was 4.4 billion years in the past. But for a galaxy cluster, this is relatively young. In fact, observations with the NASA/ESA Hubble Space Telescope and other telescopes show a cluster still in the process of being built.
