For as long as organizations have been interested in moving resources to the cloud, they\u2019ve been concerned about security. That interest is only getting stronger as cloud usage grows \u2013 making it a perfect topic for the latest #CIOTechTalk Twitter chat.\n\nThe chat brought together a host of security consultants and practitioners who weren\u2019t shy about weighing in with their thoughts on a series of questions around the main topic: how to remain secure during cloud migrations.\n\nIt\u2019s a timely topic given the rapid cloud migration currently underway. More than two-thirds of the 850 IT leaders who participated in a recent Foundry survey said they were accelerating their cloud migration. Yet, of the top 10 challenges they face, four relate to security:\n\nTo get the ball rolling, host Isaac Sacolick (@nyike) asked what main security challenges teams encounter when migrating to the public cloud. Among the responses (edited slightly for clarity; this was Twitter, after all):\n\nSacolick noted in the early days of cloud, he\u2019d see cloud-certified architects\u2019 drawings with no mention of security and wondered if things were better today.\n\nWhen asked how security teams should protect data applications and who\u2019s responsible for security, respondents were quick to answer with some variation of:\n\nBut respondents disagreed on how clear those responsibilities are to customers:\n\nWayne Anderson, a security and risk management leader at Microsoft, offered his \u201cpersonal guide to cloud security shared responsibility\u201d: \n\nNext up was the question of how on-premises assets can securely link to cloud assets, which likewise generated some healthy back-and-forth.\n\nNext the #CIOTechTalk chat focused on which governance and compliance issues organizations need to take into account before migrating to public cloud, another of the top security issues cited in the Foundry survey.\n\nThe final chat question was on how working with a partner can enhance visibility and strengthen security posture. In general, Twitter panelists supported the idea, with some caveats.\n\nFinally, Peterson had another interesting take on partnering, followed by the last word from Sacolick, the chat moderator:\n\nYou can check out the full February 2, 2023, discussion at #CIOTechTalk.
