Here is my latest blog post for Bitglass where I discuss the bit Collection 1 breach from January. It was the largest single breach by number of records, though there’s some nuance in that number that I explain in the article. https://www.bitglass.com/blog/collection-1-data-breach
Right after that post dropped, an even larger breach was reported. Needless to say, data breaches are here to stay and it’s wise for individuals to focus on mitigating the risk rather than prevention. https://www.wired.com/story/email-marketing-company-809-million-records-exposed-online/
Also, one of my previous posts got circulated on CSA. Cool! https://blog.cloudsecurityalliance.org/2019/02/08/saas-apps-and-the-need-for-specialized-security/
