I cybers\u00e4kerhetslandskapet har den kontinuerliga utvecklingen av hot gjort proaktiva \u00e5tg\u00e4rder till en n\u00f6dv\u00e4ndighet f\u00f6r alla organisationer. En s\u00e5dan \u00e5tg\u00e4rd \u00e4r PUA-skydd (Potentially Unwanted Application), en funktion i Microsoft Defender som hj\u00e4lper till att f\u00f6rhindra o\u00f6nskade programinstallationer. Genom att se till att systemen \u00e4r skyddade mot dessa potentiella hot kan IT-personal och tj\u00e4nsteleverant\u00f6rer (Managed Service Providers) avsev\u00e4rt f\u00f6rb\u00e4ttra sitt s\u00e4kerhetsl\u00e4ge.<\/p>\n
PUA-skydd, som ing\u00e5r i Microsoft Defender, \u00e4r en funktion som uppt\u00e4cker och blockerar program som inte n\u00f6dv\u00e4ndigtvis \u00e4r skadliga men som kan vara o\u00f6nskade p\u00e5 grund av deras beteende eller p\u00e5verkan p\u00e5 ett system. Betydelsen av detta manus kan inte underskattas. IT-proffs och MSP:er beh\u00f6ver verktyg f\u00f6r att s\u00e4kerst\u00e4lla s\u00e4kerheten i sina system, och att aktivera PUA-skydd \u00e4r ett av dessa viktiga verktyg. Med ett \u00f6kande antal programvaror som distribueras online \u00e4r risken f\u00f6r att oavsiktligt ladda ner och installera o\u00f6nskade program st\u00f6rre \u00e4n n\u00e5gonsin.<\/p>\n
