Every business needs to be on top of its game when it comes to matters of the security of its IT infrastructure. Because even the smallest of vulnerabilities can be exploited to devastating effect. And Microsoft Defender ATP is ready to mitigate those risks.
Not recognizing these risks can potentially cause the shutting down of a business, at best temporarily. And research has shown that the cost of downtime to a company can quite easily run into hundreds of thousands of dollars.
As we can all imagine, the losses that a business would suffer would be colossal, to say the least. Hence the need to enhance one’s security to keep bad actors at bay. By using Tamper Protection, you immediately strengthen the security of your business.
Why Tamper Protection?
Arguably the greatest challenges to an organization’s IT infrastructure come in the form of malware or malicious apps that tamper with your security settings and potentially create vulnerabilities in your system.
With these changes having been made, your organization becomes a significantly easier target for cybercriminals. It is with this in mind that Microsoft introduced Tamper Protection two years ago.
Simply put, and as the name itself implies, the Microsoft Defender ATP feature essentially locks Microsoft Defender thus preventing anyone from tampering with your security settings. Including modifications that may be made by administrators.
As a key element of Microsoft’s security strategy, Tamper Protection helps to ensure that Windows 10 clients do not need third-party anti-virus software.
However, Tamper Protection does not have an impact on third-party antivirus registration. So this means that third-party antivirus offerings will still register with the Windows Security application. By using Tamper Protection, you can prevent the following:
- Deactivation of virus and threat protection.
- Deactivation of real-time protection.
- Disabling of behavior monitoring.
- Disabling antivirus (such as IOfficeAntivirus (IOAV))
- Blocking of cloud-delivered protection.
- Removal of security intelligence updates.
Extending client coverage
With the obvious benefits that Tamper Protection brings to any organization, it only makes sense to try and extend coverage wherever possible. And this is what Microsoft did with their announcement in September last year.
This feature was extended to cover ConfigMgr 2006-only clients on both Windows 10 and Windows Server 2019, delivered via Tenant Attach. To enable Tenant Attach, the process is fairly straight forward and you can find the instructions provided here.
Having done that, you can then go to Endpoint security > Antivirus in the MEM admin center. From there you can proceed to create and deploy the Tamper Protection setting. After that, you’ll then need to configure the aforementioned setting.
This you will then deploy to a Configuration Manager collection of devices. If you want to view the policy status, go to the Monitoring > Deployments section which you find in ConfigMgr. However, you can also find it in the policy status in the Endpoint Manager Admin center
Utilizing Tenant Attach
Tenant Attach provides a method for attaching your ConfigMgr hierarchy to your tenant and leverages the capabilities available from the cloud. This includes things such as discovering cloud users and groups, synchronizing Azure AD groups from a device collection, etc.
Moreover, you can sync your on-prem only ConfigMgr clients into the MEM admin center thus enabling the delivery of Endpoint security configuration policies to your on-prem clients.
With this tool, a device does not necessarily have to be enrolled in Intune. In fact, it can be managed by either ConfigMgr or Intune. Alternatively, devices can also be co-managed.
Management of Tamper Protection
In addition to managing Tamper Protection using tenant attach as described above, there are a few other management options available. These are:
- Management of Tamper Protection using the Microsoft Defender Security Center. You can turn Tamper Protection on or off for your tenant via the Microsoft Defender Security Center. This option is on by default for all new deployments and the setting is applied tenant-wide. So it affects all devices that are running Windows 10 or Windows Server 2016 or Windows Server 2019.
- Management of Tamper Protection using Intune. If your organization’s subscription includes Intune then Tamper Protection can be turned on or off in the Microsoft Endpoint Manager admin center.
- Management of Tamper Protection on an individual device. Tamper Protection can be managed via the Windows Security app by individuals who are either home users or are not under settings managed by a security team. To do this, however, you need to have the appropriate admin permissions on your device to change security settings.
Keeping track of security data
Having preventive measures in place does not negate the need for constantly reviewing the security information.
You need to regularly check what is going on within your system so that you can stay on top of things because several tampering attempts are usually a sign of something bigger. And that may potentially be a bigger cyberattack.
Cybercriminals can attempt to alter your organization’s security settings as a way to persist and stay undetected.
Therefore, in every business, security teams should review information about such attempts, and then take the appropriate actions to mitigate threats.
The system is designed to raise alerts in the Microsoft Defender Security Center when tampering attempts are made. By utilizing tools such as endpoint detection and response and advanced hunting capabilities, you can investigate further and then implement the necessary measures to address the problem/s.
Microsoft is looking to tackle the surge in cybercrime head-on. Bad actors are constantly seeking out weaknesses in organizations’ systems and occasionally they find them. This is why businesses need to leverage the next-gen security strategies that Microsoft can offer.
With features like Tamper Protection, you get additional security to help your organization block nefarious elements from altering your security settings and leaving you vulnerable. Advanced breaches and increasing incidences of ransomware campaigns need all businesses to start getting proactive about their security. Otherwise, the consequences could prove to be very costly.
