Before you upgrade to Managed Detection and Response (MDR), Alert Logic performs an upgrade precheck to identify issues in your environment that can block your upgrade or affect its success. The following information explains the issues that the precheck can find, when the issues must be resolved, and how to resolve them.
You can use the information to prevent each issue, or you can wait for the precheck results and use the information to resolve specific issues that Alert Logic notifies you about.
Must resolve before upgrade
The following issues block a successful upgrade and must be resolved before your upgrade.
- Outdated AWS IAM role
- AWS deployments with no credentials
- Azure deployments with no credentials
- Cloud deployments that are not in OK status
- Alert Logic agent version outdated
AWS deployments must have the latest Alert Logic policy document attached to the IAM role. This issue indicates that a role is using an outdated policy document.
To get the latest policy and update the IAM role:
- In the Alert Logic console, browse to the Deployments page, click the relevant deployment tile, and then click AWS Instructions.
- Under Step 2e, click Copy Policy.
- In the AWS console, replace the existing IAM policy for the role in use for this deployment with the copied policy.
For more information, such as how to check for this issue and detailed instructions for replacing the policy in the AWS console, see Update AWS IAM Roles to Prepare for Upgrade.
AWS deployments must have an IAM role configured. This issue indicates that you need to finish configuring a deployment in the Alert Logic console.
To check for this issue prior to the upgrade precheck, browse to the Deployments page in the Alert Logic console, click an AWS deployment tile, and then click AWS Role. If the ARN field is blank, you need to create an AWS IAM role.
To create an AWS IAM role:
- In the Alert Logic console, browse to the Deployments page, click the relevant deployment tile, and then click IAM Role Setup.
- Click CLOUDFORMATION SETUP (recommended) or OR PROCEED WITH MANUAL SETUP, and then follow the instructions on the page. If you choose the CloudFormation method, the CloudFormation template completes steps in the AWS console for you.
- In the Alert Logic console, click AWS Role in the left navigation for the deployment, paste the newly created ARN into the field, and then click SAVE.
Azure deployments must have Role-Based Access Control (RBAC) configured with an app registration. This issue indicates that RBAC is not configured or was configured with a user credential method that is no longer supported.
To check for this issue
To fix this issue, see the instructions in Configure App Registration and RBAC for Microsoft Azure Resources.
The cause of this issue is typically one of these issues: Outdated AWS IAM role, AWS deployments with no credentials, or Azure deployments with no credentials. If those issues are fixed, the likely cause is Azure deployments with permission errors.
For information about how to check for and fix Azure permission errors, see Troubleshoot permission errors.
If your agent version is older than 2.9.9, Alert Logic cannot migrate it. This issue can occur if the update policy for the agent is set to Never, which does not allow Alert Logic to update the agent automatically when a new version is available.
To check for and fix the issue, complete the procedure Modify an updates policy to check the update policy, and then choose Automatic if necessary.
If your updates policy is set to Automatic, you can wait for results of the precheck, and then update the agent manually, if necessary.
To reinstall the agent manually, you must uninstall the old version, and then download and install the latest one. For more information, see:
- Uninstall the Alert Logic Agent for Linux
- Install the Alert Logic Agent for Linux
- Uninstall the Alert Logic Agent for Windows
- Install the Alert Logic Agent for Windows
Recommended but not required to fix before upgrade
These configuration issues do not prevent your upgrade, but Alert Logic recommends that you fix them. They complicate the network creation part of the upgrade and lead to many configuration exposures on the Health page. You can improve the upgrade process and reduce post-upgrade tasks significantly by ensuring your deployments are in a healthy state before your upgrade.
- Deployments with unassigned agents
- Protected hosts, log sources, or appliances that are not in OK status
Alert Logic recommends that you assign all protected hosts to an appliance or archive them before your upgrade to avoid this issue. This task prevents the creation of duplicate networks and reduces post-upgrade cleanup significantly.
To check for this issue prior to the upgrade precheck, browse to each of your deployments, click Networks and Protected Hosts, and then click the Protected Hosts tab. Check for protected hosts in new status. To review the list, you can scroll or select the By Source Status filter and then click Hosts in New State to narrow results.
If a host is listed as new, click the edit icon (), select an Assignment Policy, and then click SAVE.
Or, if you do not want to monitor this host for threats or collect its network traffic, click the archive icon (), and then click ARCHIVE.
Items that are not in OK status are some of the most important issues to resolve before your upgrade. Alert Logic recommends that you fix these issues in advance for a smoother upgrade and fewer cleanup tasks post-upgrade. After the upgrade, any items that are not fixed appear as configuration exposures on the Health page.
To check for these issues prior to the upgrade precheck, browse to each of your deployments, and then click an item in the left navigation to open the relevant page. For example, to view the list of protected hosts, click Networks and Protected Hosts, and then click the Protected Hosts tab. To review the list, you can scroll or select a status filter to narrow results.
Protected hosts, log sources, or appliances are offline— If you do not expect the offline hosts or log sources to be in use going forward, Alert Logic recommends that you archive or delete the item before the upgrade. For appliances that need to be removed, you can work with your Alert Logic implementation engineer or contact Technical Support.
Protected hosts or log sources are in error—Investigate why the item is in an error status. Alert Logic recommends that you resolve as many of the errors as possible. If a host is associated with the incorrect assignment policy, for example, this issue creates duplicate networks that require cleanup after the upgrade.
If the following issues apply to your environment, they cannot be fixed until after your upgrade. Alert Logic recommends that you plan to work on them after your upgrade to achieve the same or similar outcomes in MDR.
- AWS deployments with scanning appliance usage
- Webhook usage
- Collection alerts usage
- Scheduled report usage
If you perform vulnerability scanning in your AWS environment currently, you must deploy the scanning appliance after upgrading. For more information, see Amazon Web Services (AWS) Deployment Configuration—Manual Mode (Professional Subscription) and Scan Functionality Upgrade.
If your webhooks were created on the Cloud Defender platform before the new webhook connection experience, your webhooks do not migrate to MDR and must be reconfigured after your upgrade. For more information, see Connections.
In MDR, a health summary report notification replaces your Cloud Defender collection alerts. If you subscribe to receive collection alerts, Alert Logic schedules the Daily Health Summary report for you and subscribes the same recipients to receive a notification when the report is generated. You can change the schedule and recipients or unsubscribe. For more information, see Scheduled Reports and Notifications.
Your existing scheduled reports cannot be migrated because the Reports offering is upgraded in MDR. For help finding similar information from Cloud Defender Scheduled reports in MDR, see Managed Detection and Response Reports Upgrade. For information about scheduling the reports, see Scheduled Reports and Notifications.
Deprecated or unavailable features
The upgrade precheck detects whether the following features or services are present in your environment. Alert Logic informs you that they cannot be transferred to MDR because they are deprecated or an equivalent feature or service does not exist.
- Event Alert Rules (deprecated)
- Out-of-Band web application firewall (OOB WAF) (no equivalent feature available)
- Blocking policies (no equivalent feature available)
For more information, see Deprecated or unsupported functionality.
