Block unauthorized changes

Use case

Block unauthorized changes on your servers.

To block unauthorized changes on a server, check each one against what's approved before it runs. Mimic Networks checks each change to a protected Windows or Linux server against its known-good profile and stops unauthorized ones at the point of execution, whether a person, a script or ransomware makes them.

What Mimic does

What Mimic does on the server.

Check each change before it runs.

Mimic decides inline, before the change executes. Mimic stops exploitation at the point of execution, so a change outside the server's known-good profile doesn't take effect.

Ransomware Defense

Connect it to how you approve change.

Mimic integrates with ServiceNow through custom deployments for automated ticketing and change management. Mimic feeds enforcement events to your SIEM and SOAR platforms.

Ransomware Defense

A change outside the profile stops at the point of execution.Mimic checks each change to a protected server, such as changing a protected file, stopping a protected service or changing a registry key, against the server's known-good profile. Changes in the profile proceed. Changes outside it stop at the point of execution, and DashCam records each attempt. SOURCE A change on a protected server ATTEMPT 01 Change a protected file ATTEMPT 02 Stop a protected service ATTEMPT 03 Change a registry key Known-good profile check Was this change authorized? INSIDE THE PROFILE In the profile: proceeds OUTSIDE THE PROFILE Outside it: stopped at the point of execution DASHCAM RECORDS EACH ATTEMPT

Questions

How do you make sure only authorized changes happen on Linux servers?

Hold each Linux server to its own known-good profile and check each change against it. Enforcement runs as a file system mini-filter driver on Windows and through eBPF on Linux, with the enforcement logic in a WebAssembly sandbox implemented in Rust, from a single module on both. On Linux, Mimic protects Red Hat Enterprise Linux 8 and later.

How is this different from file integrity monitoring?

File integrity monitoring reports that a protected file changed, after it changed. Mimic checks the change before it executes and stops it when it falls outside the server's known-good profile. The profile covers more than files: it holds what the application depends on, such as its processes, services and settings.

Proof

How you'll see it work.

DashCam records each blocked attempt: what it tried to change, when and the process behind it, so the test leaves evidence you can read afterward.

Limits

Where Mimic stops.

  • Mimic Networks protects Windows Server 2016 and later, and Red Hat Enterprise Linux 8 and later.
  • It doesn't run on laptops, desktops or network devices.
  • In Maintenance Mode, Mimic suspends enforcement and keeps monitoring.
  • Mimic doesn't write your change policy or run your change board. It enforces the known-good profile your team approves.
  • The ServiceNow integration is a custom deployment, not a packaged connector.

Who it's for

For your role.

Infrastructure and server owners

Your change process works until someone goes around it. Mimic holds each protected server to the profile you approved, so a change outside it stops at the point of execution.

What is known-good enforcement?

FAQ

Frequently asked questions.

A change to a protected server that falls outside its known-good profile. The profile holds what the application depends on to run as intended, such as its files, processes, services and settings, and your team reviews it before protections turn on. A change outside it stops at the point of execution, whether it comes from ransomware, an exploited vulnerability, an AI agent or a person with valid credentials.

No reboots required. You install the Mimic Node on a supported server, it builds the server's known-good profile and your team approves the profile before protections turn on. Policy changes and upgrades don't need a reboot either. Mimic protects Windows Server 2016 and later, and Red Hat Enterprise Linux 8 and later, so check your servers against that list first.

In Maintenance Mode, Mimic suspends enforcement and keeps monitoring. That makes a maintenance window a gap in enforcement, so plan it like any other change: put a server in Maintenance Mode only for the work you approved, only for as long as the work takes and with the same approvals you'd want for the change itself.

No. Your change management process decides what's approved. Mimic enforces it on the servers it protects: changes inside the known-good profile proceed, and changes outside it stop at the point of execution. Mimic integrates with ServiceNow through custom deployments for automated ticketing and change management, and it feeds enforcement events to your SIEM and SOAR platforms.
