CISA releases a new list of open-source security tools.
One of the challenges of achieving a resilient security posture is the tech part of the trade, and this list, not only helps in that regard by offering high-quality resources but also may serve as a checklist of the foundational security measures you should be incorporating in your organisation. Leveraging these free tools will enhance your overall security posture, but could also help you discover issues you have previously overlook. This imho that is the name of the CyberSec game: Visibility and cover your bases from the beginning.
Don’t forget that tech is only part of the way, so hopefully, CISA will share in the future some resources on how to deal with the processes, procedures and people parts of the business. Moreover, disregard your doubts about implementing open source tools, because we all have chosen off-the-shelf apps from a vendor in the past because… reasons.
