Cybersecurity Lessons to Carry Into 2022

ThreatLabz' 2021 year-end review highlights four persistent high-risk areas — ransomware (including Ransomware‑as‑a‑Service and double‑extortion), supply‑chain compromises (notably SolarWinds and Kaseya), zero‑day exploits (Log4Shell and Exchange-related flaws), and advanced persistent threats — and provides actionable guidance for 2022 such as reducing attack surface, implementing SSE/ZTNA, inspecting encrypted traffic, deploying inline DLP and AI sandboxing, timely patching, and maintaining incident response and backup plans.
