While strong passwords and encryption are important, multifactor authentication (MFA) provides the most effective defense against external threat actors targeting cloud-based services. By requiring a second verification step, such as a push notification, one-time code, or hardware token, MFA ensures that even if credentials are compromised, attackers cannot gain access without the additional factor. This significantly reduces the risk of unauthorized account takeovers in cloud environments.

When you've exhausted your troubleshooting expertise and the customer is frustrated, the appropriate next step is to escalate the ticket to a more experienced technician or specialized team. At the same time, communicate clearly to the customer what you're doing and what they can expect next. This maintains transparency, manages expectations, and ensures the issue is resolved as quickly as possible.

A zero-day vulnerability refers to a security flaw that is actively exploited by attackers before the software vendor has released a patch or remediation - meaning defenders have "zero days" to prepare once the exploit becomes known.

By using port mapping (NAT) rules on the router, you can choose to forward the surveillance system's HTTP/HTTPS ports only on the LAN interface and leave them closed on the WAN side.
This ensures users on the local subnet can access the camera interface via its IP address, while external login attempts from the internet are blocked.

Key fobs (or badges) grant physical access to offices, server rooms, or secure areas. Disabling them prevents the former employee from entering the premises once their employment ends.
Suspend the user's email account
Email is often the gateway to corporate resources (password resets, sensitive communications, file sharing). Suspending the account immediately stops any further logins, prevents unauthorized access to archived emails, and blocks potential misuse.
