OpenSSH koodibaasi on lisatud sisseehitatud kaitse automaatsete paroolide \u00e4rakasutamise r\u00fcnnakute vastu, kus robotid p\u00fc\u00fcavad arvatavat parooli, katsetades erinevaid tavalisi kombinatsioone. Selliste r\u00fcnnakute blokeerimiseks on sshd_config konfiguratsioonifaili lisatud parameeter PerSourcePenalties, mis v\u00f5imaldab m\u00e4\u00e4ratleda blokeerimise piiri, mis aktiveerub suure arvu eba\u00f5nnestunud \u00fchendusp\u00fc\u00fcete korral \u00fchest IP-aadressist. Uus kaitsemehhanism j\u00f5uab j\u00e4rgmisse OpenSSH v\u00e4ljaandesse ja on vaikimisi sisse l\u00fclitatud OpenBSD 7.6-s. <\/p>\n

Kaitse aktiveerimisel hakkab sshd j\u00e4lgima alamehangete l\u00f5ppemise staatust, kindlaks tehes olukordi, kus autentimine eba\u00f5nnestus v\u00f5i kus protsess l\u00f5petati ootamatult rikke t\u00f5ttu. Suur eba\u00f5nnestumiste intensiivsus autentimisel viitab paroolide \u00e4rakasutamise katsetele ja ootamatu l\u00f5petamine v\u00f5ib viidata programmide haavatavuste \u00e4rakasutamise katsetele sshd-s. <\/p>\n

PerSourcePenalties parameetri abil m\u00e4\u00e4ratakse minimaalne k\u00fcnnis anomaalsete s\u00fcndmuste jaoks, mille \u00fcletamisel blokeeritakse IP-aadress, milles kahtlane tegevus on fikseeritud. PerSourceNetBlockSize parameetri abil saab t\u00e4iendavalt m\u00e4\u00e4rata alamv\u00f5rgu maski, et blokeerida terve alamv\u00f5rk, kuhu probleemne IP kuulub. <\/p>\n

Erinevate alamv\u00f5rkude blokeerimise v\u00e4ltimiseks on ette n\u00e4htud PerSourcePenaltyExemptList parameeter, mis v\u00f5ib osutuda kasulikuks valeh\u00e4iretega seotud olukordades, n\u00e4iteks kui SSH-serverile p\u00f6\u00f6rdub suur v\u00f5rk, mille erinevate kasutajate p\u00e4ringud tulevad sama IP l\u00f5pust adresseerimise muunduri v\u00f5i proksi kaudu.
