With the rise of sophisticated attacks, I'm worried about our current setup. What are the best practices for applying Cyber Security protocols to a multi-cloud environment? I want to ensure we are covering the basic entry points while also monitoring for lateral movement within our private networks.

To handle advanced persistent threats in a multi-cloud setup, you must move toward a Zero Trust Architecture. This means you never trust any user or device by default, even if they are already inside the network perimeter. Implement micro-segmentation to prevent lateral movement; this way, if one section is compromised, the attacker is trapped. Additionally, ensure you have centralized logging across all cloud providers so your SOC team can see a unified view of threats. Regular penetration testing and automated vulnerability scanning are also vital components of a modern defensive strategy.
Have you already implemented Multi-Factor Authentication across all your administrative accounts, or are you still relying on traditional password-based access for your cloud consoles?
Focusing on the Principle of Least Privilege is your best bet. If users only have the bare minimum access they need, the blast radius of any potential breach is significantly reduced.
Kimberly is right. Many people forget that internal permissions are just as dangerous as external vulnerabilities if they are not managed properly.
Jeffrey, we have MFA on the main consoles, but some legacy API integrations still use static keys. That is actually where I feel most vulnerable right now. We are looking into rotating those keys more frequently or moving to identity-based access for those specific services.
