Understanding the Device Risk Landscape
Before an IT professional can respond to risks, they must first understand the potential vulnerabilities and threats that devices face. Risks to devices can emerge from several vectors, including malware, unauthorized access, data leakage, and outdated software or firmware.
Use of Microsoft 365 Defender
Microsoft 365 Defender is an integral part of the risk response strategy. It provides a comprehensive security solution for identifying, preventing, and responding to threats. The Defender suite includes the following services:
- Microsoft Defender for Endpoint
- Microsoft Defender for Identity
- Microsoft Defender for Office 365
- Microsoft Cloud App Security
Reviewing Device Risks
When reviewing device risks, administrators should make regular use of the Microsoft 365 security center. This platform offers a centralized overview of the security posture, including device risk reports. Here, risks are identified across various parameters, such as:
- Security Baseline Compliance
- Advanced Threat Protection (ATP) Alerts
- Device Health and Compliance Reports
| Security Check | Description |
|---|---|
| Security Baseline Compliance | Ensures that devices adhere to the security configurations deemed necessary by Microsoft. |
| ATP Alerts | Identifies and reports potential breaches or infection attempts on devices. |
| Device Health | Highlights potential hardware or software malfunctions that could pose security risks. |
| Compliance Reports | Lists the devices that do not comply with the organization’s compliance policies. |
Responding to Device Risks
Once a risk has been identified, it must be addressed promptly. The responses can be largely categorized into two groups: automated and manual responses.
- Automated Response
With Microsoft 365 Defender, certain responses can be automated. For example, Defender for Endpoint can initiate automated investigations, which can automatically remediate certain threats without administrator intervention. Remediation actions can include the isolation of devices, killing malicious processes, or quarantining files.
- Manual Response
In some cases, a more hands-on approach is necessary. This could involve the following:
- Directing the affected user to change their credentials.
- Applying security patches or updates to vulnerable systems.
- Reconfiguring security settings on a device that is non-compliant with security baselines.
- Wiping or re-imaging compromised devices to eliminate risks and start afresh.
Communication and Training
Constant communication with end-users and training them on security best practices is crucial. Users should be informed about how to recognize phishing attempts, the importance of regular software updates, and the necessity of using strong, unique passwords.
Implementing Conditional Access Policies
Using Conditional Access policies within Microsoft 365 can ensure that only secure, compliant devices can access organizational resources. Conditional Access can be configured based on:
- The user’s identity
- Device health
- The type of application being accessed
Continuous Monitoring and Assessment
The landscape of cybersecurity is always changing, and so should the strategies used to combat its threats. Regular assessments should be carried out to review the effectiveness of the current risk response processes, and updates should be made as necessary.
Examples
An example could include an ATP alert indicating a device has been accessed from a risky IP address. The automated response could quarantine the device, and the manual follow-up would involve the security team investigating the origin of the access attempt.
Another example would be an alert about an outdated operating system missing critical security patches, potentially causing non-compliance with security baselines. The response would require ensuring that all patches are deployed promptly to the affected devices.
In conclusion, the process of reviewing and responding to device risks within Microsoft 365 Mobility and Security involves a combination of technological solutions and proactive security practices. The MS-101 certification ensures that IT professionals have the necessary skills and knowledge to effectively protect their organization’s devices from the multitude of threats they face every day.
