CERT-SE:s veckobrev v.17

Det är många som eldar på säkerhetsarbetet i dessa tider, och det finns en hel del stöd och vägledning för organisationer att ta del av på bland annat informationssakerhet.se. Vidare har CISA publicerat en lista med de mest utnyttjade sårbarheterna som även inkluderar de mest utnyttjade sårbarheterna 2021. Listan kan vara behjälplig när det gäller att göra priotiteringar i säkerhetsarbetet. Läs också i detta veckobrev om hur du uppnår "best practises" inom cybersäkerhet enligt NIST.

Trevlig Valborg! Elda lugnt!
