Bunun sonucunda da siber su\u00e7larda art\u0131\u015f trendi ba\u015f g\u00f6sterdi. 2020 y\u0131l\u0131 itibariyle siber su\u00e7lar yakla\u015f\u0131k 6 kat\u0131na \u00e7\u0131kt\u0131.<\/p>\n

Ki\u015fisel bilgisayarlar\u0131n yeterince korunmamas\u0131, bilin\u00e7sizce a\u00e7\u0131lan mailler ve siteler 2020\u2019de siber sald\u0131r\u0131lar\u0131n artmas\u0131na katk\u0131 sa\u011flad\u0131. Ayn\u0131 zamanda siber sald\u0131r\u0131ya u\u011framalar\u0131na ra\u011fmen fark\u0131nda olmayan, umursamayan insan say\u0131s\u0131nda da art\u0131\u015f ya\u015fand\u0131. \u00d6rne\u011fin Amerika Birle\u015fik Devletleri\u2019ndeki insanlar\u0131n %64\u2019\u00fc bir data ihlalinden etkilenip etkilenmedi\u011fini kontrol etmemekte. Yeni normalde zararl\u0131 yaz\u0131l\u0131mlara her dakikada 2000 ki\u015fi maruz kal\u0131yor.<\/p>\n

Siber salg\u0131ndan korunmak \u00e7ok zor de\u011fil. Yeni gelen g\u00fcncellemeleri indirmek dahi siber sald\u0131r\u0131lara kar\u015f\u0131 korunmakta etkili. \u0130nsanlar\u0131n, \u00f6zellikle bu s\u00fcre\u00e7te t\u0131klayacaklar\u0131 internet linklerini iki defa d\u00fc\u015f\u00fcnmelerinde fayda var. \u0130nternet kullan\u0131c\u0131lar\u0131 g\u00fcvenmedikleri linklere girmeyerek kendilerini bir miktar izole edebilirler.<\/p>\n

Bu durum sadece bilgisayar kullan\u0131m\u0131yla s\u0131n\u0131rl\u0131 de\u011fil. Gittik\u00e7e geli\u015fen ak\u0131ll\u0131 telefonlar da siber korsanlar i\u00e7in bir hedef durumunda. Yeni normalde indirilen uygulamalara dikkat etmek daha fazla \u00f6nem arz etmekte. Telefona indirilen basit bir uygulama veya a\u00e7\u0131lan \u00f6nemsiz bir mail linki t\u00fcm bilgilerin \u00e7al\u0131nmas\u0131na yol a\u00e7abilir.\u00a0 Bu s\u00fcre\u00e7te telefonlar\u0131nda bilgisayarlar kadar korunmas\u0131 da \u015fart hale gelmekte.<\/p>\n

\u015eifreler siber su\u00e7lular\u0131n odakland\u0131\u011f\u0131 noktalardan biri. \u0130nsanlar\u0131n do\u011fum g\u00fcnlerini \u015fifre olarak koymalar\u0131 ak\u0131lda kalmas\u0131n\u0131 kolayla\u015ft\u0131rd\u0131\u011f\u0131 kadar k\u0131r\u0131lmas\u0131n\u0131 da kolayla\u015ft\u0131r\u0131yor. Koyulan \u015fifreleri komplike se\u00e7mek, i\u00e7erlerine say\u0131, b\u00fcy\u00fck harf gibi i\u015faretleri yerle\u015ftirmek \u015fifrelerin g\u00fcvenli\u011fini artt\u0131ran unsurlar.<\/p>\n

Evde ge\u00e7irilen bolca zamanla<\/a> beraber insanlar \u00f6deme yapmaktan ka\u00e7arak korsan yaz\u0131l\u0131mlar\u0131 kullanmay\u0131 tercih edebiliyorlar. Korsan yaz\u0131l\u0131mlar kaynaklar\u0131 belirsiz oldu\u011fundan dolay\u0131 g\u00fcvenilirlik sa\u011flamamakta. Ayr\u0131ca KPMG\u2019nin ara\u015ft\u0131rmas\u0131n g\u00f6re korsan yaz\u0131l\u0131m kullan\u0131m\u0131n\u0131n yayg\u0131n oldu\u011fu \u00fclkelerde siber su\u00e7a maruz kalma miktar\u0131 da ayn\u0131 oranda y\u00fcksek.

Siber korsanlarda bu oranlar b\u00fcy\u00fcm\u00fc\u015f g\u00f6z\u00fckmekte. Dikkat edilmedi\u011fi takdirde \u00e7ok b\u00fcy\u00fck sonu\u00e7larla kar\u015f\u0131la\u015f\u0131labilecek bu konuda insanlar\u0131n \u00f6nlemlerini sa\u011flam almas\u0131nda fayda oldu\u011fu uzmanlar taraf\u0131ndan belirtilmekte.<\/p>\n

Siber su\u00e7lar\u0131n bu derece art\u0131\u015f g\u00f6stermesi, sadece bireysel kullan\u0131c\u0131lar\u0131 de\u011fil; kurumsal yap\u0131lar\u0131, devlet kurumlar\u0131n\u0131 ve kritik altyap\u0131lar\u0131 da tehdit etmektedir. \u00d6zellikle sa\u011fl\u0131k, finans, enerji ve lojistik sekt\u00f6rlerinde faaliyet g\u00f6steren kurulu\u015flar bu tehditlerin ba\u015fl\u0131ca hedefleri aras\u0131ndad\u0131r.

Bu da yaln\u0131zca ekonomik de\u011fil, ayn\u0131 zamanda hayati kay\u0131plarla sonu\u00e7lanabilecek g\u00fcvenlik a\u00e7\u0131klar\u0131n\u0131 beraberinde getirmi\u015ftir.<\/p>\n

2020 y\u0131l\u0131nda yap\u0131lan analizlere g\u00f6re, fidye yaz\u0131l\u0131mlar\u0131nda ciddi bir art\u0131\u015f g\u00f6zlenmi\u015f; bir\u00e7ok kurum sistemlerine eri\u015fimi yeniden kazanmak i\u00e7in b\u00fcy\u00fck miktarda fidye \u00f6demek zorunda kalm\u0131\u015ft\u0131r. Siber su\u00e7lular, \u00f6zellikle pandemi nedeniyle zaten zorlanan kurumlar\u0131n \u00e7aresizli\u011finden faydalanarak bu t\u00fcr sald\u0131r\u0131lar\u0131 yo\u011funla\u015ft\u0131rm\u0131\u015ft\u0131r. Fidye yaz\u0131l\u0131mlar\u0131nda ortalama talep edilen \u00fccretin de 2020 itibariyle %80 artt\u0131\u011f\u0131 bildirilmektedir.<\/p>\n

\u00d6te yandan, uzaktan \u00e7al\u0131\u015fman\u0131n kal\u0131c\u0131 hale gelmesiyle birlikte, siber g\u00fcvenlik politikalar\u0131 sadece IT departmanlar\u0131n\u0131n sorumlulu\u011funda kalmamal\u0131d\u0131r. \u015eirket \u00e7al\u0131\u015fanlar\u0131n\u0131n temel d\u00fczeyde siber g\u00fcvenlik fark\u0131ndal\u0131\u011f\u0131na sahip olmalar\u0131 gerekmektedir. \u00c7al\u0131\u015fanlar\u0131n d\u00fczenli aral\u0131klarla e\u011fitim almas\u0131, g\u00fcvenli ba\u011flant\u0131lar \u00fczerinden sisteme eri\u015fim sa\u011flamas\u0131, VPN kullan\u0131m\u0131 gibi uygulamalar art\u0131k kurumlar i\u00e7in standart prosed\u00fcr haline gelmelidir. Bu noktada, “insan fakt\u00f6r\u00fc” siber g\u00fcvenli\u011fin en zay\u0131f halkas\u0131 olarak g\u00f6r\u00fclmekte ve e\u011fitim, bu zay\u0131fl\u0131\u011f\u0131 bertaraf etmekte kilit rol oynamaktad\u0131r.<\/p>\n

Ayr\u0131ca, yapay zek\u00e2 destekli siber g\u00fcvenlik \u00e7\u00f6z\u00fcmlerinin de \u00f6nemi giderek artmaktad\u0131r.

Mobil cihazlar\u0131n siber g\u00fcvenlik a\u00e7\u0131s\u0131ndan a\u00e7\u0131k hedefler haline gelmesiyle birlikte, biyometrik kimlik do\u011frulama sistemleri de yayg\u0131nla\u015fmaktad\u0131r. Parmak izi, y\u00fcz tan\u0131ma ve retina taramas\u0131 gibi y\u00f6ntemler, \u015fifrelerin yerini alarak daha g\u00fcvenli bir eri\u015fim katman\u0131 olu\u015fturmakta; ancak bu sistemlerin de sahtecili\u011fe kar\u015f\u0131 dayan\u0131kl\u0131l\u0131\u011f\u0131 s\u00fcrekli olarak test edilmelidir.<\/p>\n

Sonu\u00e7 olarak, dijitalle\u015fmenin h\u0131zland\u0131\u011f\u0131 ve internet kullan\u0131m\u0131n\u0131n g\u00fcnl\u00fck ya\u015fam\u0131n ayr\u0131lmaz bir par\u00e7as\u0131 haline geldi\u011fi bu \u00e7a\u011fda, siber g\u00fcvenli\u011fe<\/a> yap\u0131lan yat\u0131r\u0131m art\u0131k bir se\u00e7enek de\u011fil zorunluluktur.
