CISA Holidays and Weekends Security Reminder for Critical Infrastructure- Introduction

On November 22, 2021, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) issued a notice titled, “Reminder for Critical Infrastructure to Stay Vigilant Against Threats During Holidays and Weekend.”

Over a number of posts to follow, IP Probe Blog will take a dive into the links made available in the notice that provide more specific information.

The CISA reminder initially highlights a few fundamentals out of the gate:

• Identify IT security employees for weekends and holidays who would be available to surge during these times in the event of an incident or ransomware attack. 
• Implement multi-factor authentication for remote access and administrative accounts.
• Mandate strong passwords and ensure they are not reused across multiple accounts. 
• If you use remote desktop protocol (RDP) or any other potentially risky service, ensure it is secure and monitored. 
• Remind employees not to click on suspicious links, and conduct exercises to raise awareness.

*In our next post, we will review CISA’s recommended, “Best Practices and Mitigations” during the Holiday Season and weekends.
