varaidzo

vanozvishandisa zvakawandisa Internet chete nokuda kuziva kana mafaro Interests: "? DDoS kurwisa - chii uye sei kuita" Naizvozvo, pane zviitiko apo ruzivo hackers zvokungonakidzwa uye mharidzo mauto kuronga kurwisa izvozvo chero mari.

Pamwe zvikonzero DDoS kurwisa vane kupatsanura dzavo zvinhu.

1. Bandwidth. Nhasi, anenge ose kombiyuta iri akashongedzerwa ane nzvimbo kana munharaunda nzvimbo network, kana kungoti paIndaneti. Naizvozvo, pane nyaya ichizadza nemambure - vakawanda zvikumbiro vane malformed uye asingabatsiri anyatsoita chaizvo zvinhu kana midziyo nechinangwa chawo unozotevera kukundikana kana atadze kushanda zvakanaka (kukurukura migero, dzakaoma Zvifambiso, ndangariro, etc.).
2. Kuneta hurongwa. Akadaro DDoS kurwisa Server Samp wakaitwa akakunda mumuviri ndangariro, CPU nezvimwe gadziriro zvinhu, nokuda kusavapo iyo vakarwisa chinhu hazvimboiti kuti zvakazara kushanda.
3. Looping. Zvisingaperi ongororo Data nezvimwe zvinogara, vachiita "denderedzwa", kumanikidza chinhu kutambisa yakawanda zvinhu, nokudaro clogging kumusoro ndangariro pamberi rakwo okuneta.
4. Kurwisa venhema. Sangano iri rinotarisira dzenhema aramu dziviriro mugadziriro, iyo pakupedzisira inotungamirira kuti blockage vamwe zvinhu.
5. HTTP Protocol. Hackers kutumira maloomkie yacho HTTP-Mabhokisi uchinyanya encryption, mumwe zvekuvaka Chokwadi, haaoni kuti yakarongwa DDoS kurwisa, purogiramu nokuda Server, vachiita basa ravo, izvozvo anotumira mhinduro omumasherufu vari yakakura chinzvimbo, nokudaro clogging ari bandwidth rechipfuwo, izvo kunotungamirira zvakare kuti kukundikana basa.
6. Smurf kurwisa. Uyu ndiwo mumwe kwemarudzi zvikuru ngozi. A Hacker uri nhepfenyuro mugero anotumira akuvara Kunyepa, ari ICMP packet, apo kero akuvara kuchatsiviwa kero zvebhinya, uye nodes zvose vari kutanga kutumira mhinduro kuna ping chikumbiro. This DDoS Kurwisa - .. Program, zvainanga kushandiswa hombe network, kureva, chikumbiro kupatsanurwa kuburikidza pamakombiyuta 100, achapiwa yakakura nokuda ka100.
7. UDP-mafashamo. Izvi mhando kurwisa fananei yapfuura mumwe, asi panzvimbo ICMP omumasherufu, vavengi vanoshandisa UDP-omumasherufu. Musimboti Nzira iyi kutsiva IP-Kero zvokupedzisira Kero Hacker uye kushandisa zvizere bandwidth kuti achaita kuti nyika ino anorovera.
8. Syn-mafashamo. Kumurwisa kuedza kumhanya panguva vazhinji TCP-Syn-kubatana nenzira ane kururama kana pasina kero. Mushure kuedza anoverengeka, vakawanda anodawo hurongwa akaisa munzvimbo matambudziko kubatana uye mushure nth nhamba kuitwa chete kuvhara nayo. Syn-rukova gwara rakanyatsojeka guru, uye nokukurumidza pashure dzinoverengeka kuitwa, munhu wacho chinoumba anoramba kuzarura chero kubatana itsva, ichivharira yose network.
9. "Heavy Mabhokisi". Izvi mhando inopa mhinduro yomubvunzo wokuti: "Chii DDoS Kurwisa Server" Hackers kutumira omumasherufu nhengo Server, asi saturation kuti bandwidth zvikasaitika, asi chiito chinotungamirwa chete panguva CPU nguva. Somugumisiro, Mabhokisi izvi kutungamirira kukundikana munyika, uye, akavapindurawo, anoramba tinopinda kuna nezviwanikwa zvayo.
10. Log mafaira. Kana kota maitiro uye kutenderera kuchengeteka pakakoromorwa, imwe anokwanisa kutuma guru Vhoriyamu omumasherufu, saka kutora zvose vakasununguka nzvimbo pamusoro zvakaoma dhisiki Server.
11. Chirongwa yekubvuma. Hackers mamwe ruzivo chinogona kuongorora maumbirwo rechipfuwo server kumhanya anokosha algorithms (DDoS kurwisa - vanoshandisa chirongwa). Kurwisa kwakadaro anonyanya zvainanga patsime anodzivirirwa zvokutengeserana mabasa akaitwa uye masangano yeminda siyana uye munzvimbo. Kumurwisa vari kuwana pokunzvenga napo vari bumbiro uye kumhanya mirayiridzo haushandi kana zvimwe chete algorithms kuti kutungamirira pakaita kumisa hurongwa kana basa.

All kushanda zvinhu dziri chete nzvimbo inofanira kugoverwa uye akaronga kurutivi samambure kero, kana kunyange imwe nyika. Izvi zvichaita kuti vapone chero kurwiswa uye chengeta dzomunyika IT mamiriro.

Services kuti vadzivirirwe DDoS-kurwisa

Achiudza zvose pamusoro dambudziko DDoS-kurwisa (chii uye sei kurwisa), tinogona pakupedzisira kupa zano rakanaka. Masangano makuru vazhinji vanopa mabasa avo kudzivirirwa uye kurapwa kurwiswa zvakadaro. Zvikurukuru, makambani aya achishandisa siyana nezviyero uye zvakasiyana-siyana zvigadziriswe kudzivirira basa renyu neevakawanda DDoS-kurwisa. Pane kushanda nyanzvi uye nyanzvi mumunda yavo, saka kana iwe hanya hwako, zvakanakisisa (kunyange zvakachipa) Ipfungwa aizova kukumbira kune mumwe makambani avo.

Sei DDoS-kurwisa nemaoko avo pachavo

Ziva, ari forearmed - yakasimba musimboti. Asi yeuka kuti sangano nemaune DDoS-kurwisa, oga kana vari boka revanhu - tsotsi mhosva, saka mashoko aya inowaniswa kutungamirirwa chete.

American IT vatungamiri kudzivisa kutyisidzira kwakasimbiswa chirongwa kuedza kurwisa kusimbisa servers uye mukana DDoS-aizotambudzazve hackers, uchiteverwa kuchaitwa kurwiswa.

Sezvinotarisirwa, 'kupisa' pfungwa akatendeuka zvombo izvi pamusoro Developers pachavo uye pamusoro chii akarwa. The zita bumbiro chigadzirwa - Loic. software iyi kuchiwanikwa pachena uye, pfungwa, hakubvumidzwi nemutemo.

Inowanikwa uye functionality purogiramu iri nyore, unogona kubatsirwa munhu anofarira DDoS-kurwisa.

How kuita zvose pachangu? Mitsetse inowanikwa zvakakwana kupinda IP-chibayiro, ipapo vakapisa TCP uye UDP Rwako uye uwandu zvikumbiro. Voila - kurwisa kwacho kwakatanga mushure vachisundira bhatani kukosheswa!

Chero zvakakomba pfuma, Chokwadi, haazobvumira kubva software iyi, asi vanogona zvimwe zvinetso zviduku.
