Pezani momwe ziwerengero zimathandizira kuti bokosi lanu likhale loyera
Zosakaniza za spesi za Bayesian zimapangitsa kuti uthenga ukhale spam kuchokera pa zomwe zili mkati. Mosiyana ndi zojambulidwa zosavuta zowonjezera, kufotokozera kwa spam ku Basesi kumaphunzira kuchokera ku spam komanso kuchokera ku makalata abwino, zomwe zimapangitsa njira yodalirika yotsutsana ndi spam yomwe imabwereranso zabwino zonyenga.
Kodi Mumadziwa Bwanji Zopanda Zamtengo Wapatali?
Ganizirani momwe mumadziwira spam . Kuwona mwamsanga nthawi zambiri kumakhala kokwanira. Inu mukudziwa chomwe spam ikuwoneka, ndipo inu mukudziwa makalata abwino amawoneka ngati.
Mpata wa spam wowoneka ngati makalata abwino uli pafupi ... zero.
Kujambula Zosakaniza Zogwiritsira Ntchito Zosakaniza Sindikusintha
Kodi sikungakhale zabwino ngati osakaniza spam okhazikika ntchito monga choncho, nawonso?
Kulemba zojambulidwa zosakanizika zosawerengeka kuyesa izo. Amayang'ana mawu ndi zizindikiro zina monga spam. Chilichonse cha chikhalidwe chimapatsidwa mpikisano, ndipo chiwerengero cha spam cha uthenga wonse chiwerengedwera kuchokera pazowerengedwa. Ena akulemba zojambulira amayang'ana maonekedwe a maimelo olondola, kutsika mapeto omaliza a uthenga.
Njira zowonongeka zamagetsi zimagwira ntchito, koma imakhalanso ndi zovuta zambiri:
- Mndandanda wa maonekedwe amamangidwa ndi spam (ndi makalata abwino) omwe amapezeka kwa injini ya fyuluta. Kuti mumvetse bwino momwe spam aliyense angapezere, makalata ayenera kusonkhanitsidwa pa mazana a ma email. Izi zimafooketsa zowonongeka za zowonongeka, makamaka chifukwa maonekedwe a makalata abwino adzakhala osiyana kwa munthu aliyense , koma izi sizingaganizidwe.
- Makhalidwe omwe mumayang'ana ndi ocheperapo mwala . Ngati spammers amayesetsa kusintha (ndi kupangitsa ma spam kuwoneka ngati makalata abwino kwa osungira), zizindikiro zoyenera ziyenera kusinthidwa pamanja - khama lalikulu kwambiri.
- Zotsatira za mawu aliwonse mwina zimachokera pa kulingalira kwakukulu, koma akadakalibe. Ndipo monga mndandanda wa zizindikiro, sizikugwirizana ndi kusintha kwa dziko la spam kawirikawiri kapena zosowa za munthu aliyense.
Zisudzo Zowonongeka za Bayesian Zidzisokoneza, Kupeza Zabwino ndi Zabwino
Zosefera zazitsulo za Bayesian ndizojambula zosakaniza zozikidwa, komanso. Njira yawo imathetsa mavuto a zojambula zojambula zopanga spam, ngakhale, ndipo zimatero kwambiri. Popeza kuti zofooka za zojambula zojambula zili m'ndandanda wamakhalidwe ndi zolemba zawo, mndandandawu umachotsedwa.
M'malomwake, osungunula a mtundu wa Bayesian amapanga mndandanda wokha. Choyambirira, mumayamba ndi (lalikulu) maimelo omwe mwawaika ngati spam, ndi gulu lina la makalata abwino. Zosefera zimawoneka zonsezo ndikuyesa makalata ovomerezeka komanso spam kuti apeze mwayi wa maonekedwe osiyanasiyana omwe akuwonekera pa spam, ndi ma mail abwino.
Momwe Filesi ya Spam yaSazesi imayendera Imelo
Zizindikiro za fyuluta yaku spam ya Bayesan yomwe ingayang'ane ikhoza kukhala:
- mawu mu thupi la uthenga, ndithudi, ndi
- mitu yake (otumiza ndi njira zamtundu , mwachitsanzo!), komanso
- mbali zina monga HTML / CSS code (monga mitundu ndi maonekedwe ena), kapena ngakhale
- mau awiri, mawu ndi
- Meta zambiri (mwachitsanzo mawu ena amapezeka, mwachitsanzo).
Ngati mawu, "Cartesian" mwachitsanzo, sapezeka konse mu spam koma kawirikawiri mu imelo yolondola yomwe mumalandira, mwinamwake kuti "Cartesian" imasonyeza spam ili pafupi ndi zero. "Toner", kumbali inayo, imawonekera kokha, ndipo nthawi zambiri, mu spam. "Toner" ili ndi mwayi waukulu kwambiri wopezeka mu spam, osati pansi pa 1 (100%).
Pamene uthenga watsopano ufika, umayesedwa ndi fyuluta ya spesi ya Bayesi, ndipo mwayi wa uthenga wathunthu kukhala spam umagwiritsidwa ntchito pogwiritsa ntchito maonekedwe.
Tenga uthenga uli ndi "Cartesian" ndi "toner". Kuchokera m'mawu awa okha sichinaoneke ngati tili ndi spam kapena maimelo ovomerezeka. Makhalidwe ena adzakhala (mwachiyembekezo komanso mwinamwake) akuwonetsa mwayi womwe umalola fyuluta kugawa uthenga ngati spam kapena makalata abwino.
Ma Filesi a Bayesian Angaphunzire Mwachangu
Tsopano popeza tili ndi mndandanda, uthenga ukhoza kugwiritsidwa ntchito pophunzitsa fyulutayo. Pachifukwa ichi, mwina mwayi wa "Cartesian" wosonyeza makalata abwino amachepetsedwa (ngati uthenga umene uli ndi "Cartesian" ndi "toner" umapezeka ngati spam), kapena kuti "toner" yomwe ikuwonetsa kuti spam iyenera kuyang'aniranso.
Pogwiritsira ntchito njirayi, ma filters a Bayesian angaphunzire pazokha komanso pazisankho za wogwiritsa ntchito (ngati akuwongolera molakwika ndi osungira). Kusintha kwa Bayesian kusinthasintha kumatsimikiziranso kuti iwo amagwira ntchito kwambiri kwa munthu aliyense wamtundu wa imelo. Ngakhale kuti spam ya anthu ambiri ingakhale ndi makhalidwe ofanana, makalata ovomerezeka ali osiyana kwambiri ndi aliyense.
Kodi Spammers Angatani Kuti Apeze Zithunzi Zakale za ku Bayesi?
Makhalidwe a makalata olondola ndi ofunika kwambiri poyeretsa spam ya Bayesi monga spam. Ngati zowonongeka zimaphunzitsidwa mwachindunji kwa aliyense wogwiritsa ntchito, spammers adzakhala ndi nthawi yovuta kwambiri kugwira ntchito kuzungulira aliyense (kapena ngakhale anthu ambiri) osakaniza spam, ndipo zosungira zimatha kusintha pafupifupi chirichonse chimene spammers amayesa.
Ma spammers amapangitsa kuti apite ma filters ophunzitsidwa bwino a Bayesi ngati apanga mauthenga awo a spam akuwoneka bwino ngati amelo wamba omwe aliyense angapeze.
Anthu oterewa samakonda kutumiza maimelo omwewo. Tiyerekeze kuti izi ndi chifukwa maimelo awa samagwira ntchito ngati imelo yosasintha. Kotero, mwayi iwo sangakhale akuchita pamene maimelo wamba, osangalatsa ndi njira yokhayo yoperekera zosakaniza za spam.
Ngati spammers amasinthasintha maimelo ambiri, komabe, tidzawona spam ambiri mu Makalata athu a Makalata, ndipo imelo ikhoza kukhala yokhumudwitsa monga momwe zinaliri masiku a kale a Bayesian (kapena oposa). Zidzakhalanso zowononga msika wa mitundu yambiri ya spam, komabe, choncho sizatha kwa nthawi yayitali.
Zizindikiro Zamphamvu Zingakhale Filesi ya Spesies & Springs & Achi; & # 39; s Achilles & # 39; Chida
Chinthu chimodzi chokha chingatheke kuti spammers azigwira ntchito yawo kupyolera muzitsulo za Bayesian ngakhale momwe iwo aliri. Ndili chiwerengero cha ziwerengero za ku Bayesi zomwe mawu amodzi kapena maonekedwe omwe amawonekera kawirikawiri pamakalata abwino akhoza kukhala ofunika kwambiri kuti atembenuzire uthenga uliwonse kuchokera kuoneka ngati spam kuti uwerengedwe ngati ham ndi fyuluta.
Ngati spammers akupeza njira yodziwitsani mawu abwino otumizira makalata-pogwiritsira ntchito mapepala a kubwerera kwa HTML kuti muwone mauthenga omwe mumatsegula, mwachitsanzo-, akhoza kuika limodzi mwa makalata opanda pake ndikufika nanu kudzera mumtundu wabwino, fyuluta yophunzitsidwa ya ku Bayesian.
John Graham-Cumming wakhala akuyesera izi polola mafotolo awiri a ku Bayesi akutsutsana, "zoipa" zomwe zimagwirizana ndi mauthenga omwe amapezeka kuti adutse mu "fyuluta" yabwino. Akuti imagwira ntchito, ngakhale kuti njirayi ndi yowononga nthawi komanso yovuta. Sitikuganiza kuti tidzawona zochuluka za izi zikuchitika, osachepera kwambiri, ndipo sizikugwirizana ndi zizindikiro za imelo zaumwini. Anthu oterewa akhoza (kuyesa) kuwona mawu ena a mabungwe (chinachake monga "Almaden" kwa anthu ena ku IBM mwinamwake?) Mmalo mwake.
Kawirikawiri, spam nthawi zonse idzakhala (mosiyana) yosiyana ndi imelo nthawi zonse kapena sizidzakhala spam, ngakhale.
Mfundo Yofunika Kuyikira: Kulimba kwa Bayesian & # 39; s Kungakhale Kufooka Kwake
Zosefera zawasesian zopopera zili zokhutira zokhazikika zomwe:
- Amaphunzitsidwa bwino kuti adziwe spam wamtundu wina ndi machesi abwino , kuwapangitsa kukhala ogwira mtima kwambiri ndi ovuta kuwongolera kwa spammers.
- Zingathe mosalekeza komanso popanda khama kapena kusanthula mwatsatanetsatane kusinthira njira zamakono za spammers.
- tengani makalata abwino a mtumiki aliyense payekha ndikukhala ndi vuto lachinyengo kwambiri .
- Mwamwayi, ngati izi zimapangitsa kuti anthu asamakhulupirire bayizian anti-spam zowonongeka, zimakhala zolakwitsa kwambiri . Zotsutsana ndi zolakwika zabodza (spam zomwe zikuwoneka chimodzimodzi ngati makalata nthawi zonse) zimatha kusokoneza ndi kukhumudwitsa ogwiritsa ntchito.
