Cybersecurity Best Practices for Operating Commercial Unmanned Aircraft Systems

The DHS Cybersecurity and Infrastructure Agency (CISA) has published a document on cybersecurity best practices for operating commercial unmanned aircraft systems (UASs).

Incident Response Ransomware: Part One

TrustedSec has published the first blog in what it says will become a three-part series on responding to a ransomware incident. Part one provides an introduction into what ransomware is, how it works, and how it spreads to systems within an organization. It also describes different types of ransomware and variations of ransomware tactics. While part two in this series will go more into the attack kill chain, this first segment provides an overview of the sequence of events that occur during infection. Part two will also discuss more of the ways to detect, protect, and prevent ransomware.

Building a Culture of Cyber Preparedness

Daniel Kaniewski, the deputy administrator for resilience at FEMA, has written an article on the importance of incorporating cybersecurity into overall preparedness efforts.
