Sophos has just released Sophos UTM 9.506 on AWS. They have added several new features specifically designed for customers in AWS. With this release, they have introduced the usage of an AWS Profile for deploying OGW, a new update page in WebAdmin, the reduction of permissions needed for Auto Scaling deployments, and included InSpec for checking the health state of a UTM instance. In addition to that, the failover time for the High Availability deployments has been significantly improved.
AWS Profile for OGW
To increase flexibility when it comes to permissions and roles used by the UTM on AWS Auto Scaling deployment, they have introduced the possibility to attach an AWS Profile to deploy and monitor the Outbound Gateway. This makes it possible for customers to establish privilege separation in their OGW installations. Please see the knowledge base article How to create an AWS profile for automatically deployed OGWs for further details.
Customers already using OGW will also need to follow the KBA to create a new profile and attach it to their existing OGW configuration. Without the profile the OGWs still work as expected and are listed in the WebAdmin, but managing them won’t be possible any longer.
New update page in WebAdmin
Sophos have restructured the update page in WebAdmin for the High Availability and Auto Scaling customers. They have learned that most of the customers use modified templates to deploy UTM on AWS products. In order to avoid overwriting of their modified templates, they have removed the automated update but added helpful details to the page to ease the process.
The page now shows the AMI ID, a link to the release notes as well as the option to directly navigate to the current stack in the AWS Management Console. In addition to that, links to the most recent template for the deployment type and the changelog are provided.
If no update is available, the WebAdmin page shows information about the current version as well as the details stated above.
Reduced permissions needed for Auto Scaling deployments
Sophos have listened to the customers who were stating that the permissions needed for the Auto Scaling deployment are too broad and potentially aggressive. Thus, they have further reduced the permissions needed for the Auto Scaling deployments in order to align with the principle of least privilege. Please see the changelog and the updated documentation of the permissions on GitHub for more details.
InSpec on UTM on AWS
In order to make it possible for the customers to verify that the UTM on AWS works as expected, they have introduced InSpec on the UTM on AWS. InSpec is an audit and test framework developed by Chef.
InSpec will be used to check whether:
- S3 resources are available and accessible.
- System services are running.
- Important ports are accessible.
- PostgreSQL databases exist and contain the correct schema.
- System configuration files exist.
- Log files do not contain any severe errors.
The knowledge base article How to use InSpec on the UTM on AWS covers the usage of InSpec as well as how to write custom profiles to extend the solution.
Faster failover for High Availability
Customers relying on our High Availability deployment will now see a reduced failover time resulting in lower downtime.
Disable backend pooling for the WAF on Auto Scaling
Sophos have disabled the backend pooling for the Web Application Firewall for the Auto Scaling deployment now by default. This supports scenarios where load balancers with quickly changing DNS entries reside behind the UTM on AWS.
