Cloudhouse Urgent Security Update Support Process

Applies to: Cloudhouse Compatibility Packages/Containers

01/12/2021 Cliff Hobbs   ID: 407795

It is feasible that over time, Cloudhouse identifies an issue in its software that inadvertently leads to a security breach. This could potentially allow malicious actors to exploit and compromise a Cloudhouse Application Compatibility Package (formerly known as Cloudhouse Compatibility Containers™), causing a security breach for our Customers.



The term Compatibility Package covers both Cloudhouse Compatibility Packages and Containers.

To be able to address such issues quickly, we have created the process detailed in this article to alert and address any identified issues with our Customers. 

Intended Audience

Everyone involved in the deployment, management, and support of the Cloudhouse software should be aware of this process.


All Cloudhouse projects require our Customers to provide two contact email addresses for support liaison as part of the transition from 'Project Control' to 'Business As Usual'.

We log these email addresses in our Dynamics CRM system in a reportable field.


To remove risks such as one or both individuals being on holiday or leaving the company, we recommend at least one of these email addresses is a generic department address.

We also recommend Customers add the email address to their whitelists to avoid emails sent from it being incorrectly filtered.

Process Trigger

The trigger that there is an urgent fix that needs deploying comes from the Quality Assurance (QA) Manager who acts as the Release authority.

The QA Manager will be supplied with release notes based on the update detailing the:

  • Impacted versions, which may be specific version numbers or all versions after a known good version.
  • Issues
  • Resolutions

The QA Manager notifies the following personnel that this process needs to be initiated:

  • Chief Delivery Officer
  • Chief Technical Officer
  • Head of Support

Alerting Process

On identifying an issue:

  1. The Head of Support (or their delegate) runs a script against all Compatibility Packages held in the Cloudhouse Github repository to determine which Compatibility Packages are affected. 
  2. Once the affected Compatibility Packages are identified, their owners can be ascertained.
  3. The technical contact emails for the affected Customers can then be sourced from the Cloudhouse Dynamics CRM and used to create a mailing list.
  4. A standard email will then be created (see the example notification email at the end of this article) and sent to the mailing list.
  5. Cloudhouse will keep a central record of any undelivered items and confirmation of any receipt/response.
  6. Cloudhouse will also update the banner on the Cloudhouse Online Knowledge Base ( to advise an update is required, including a link to an article containing further information.

Remediation Process

The email sent as part of the alerting process requests the Customer to verify they are still utilising the affected Container and if so, to email

Once Cloudhouse Support receives this email, they will raise a support ticket then check the status of the Customer's support contract, which will be one of the following:

See the relevant section for further details.

Customer is on a current Subscription License, or a Perpetual License with an up to date Support and Maintenance Contract

Cloudhouse Support will verify the latest version of the Container in use against the Compatibility Packages on record. If the latest version is still impacted, Cloudhouse Support will work with the Customer to update to the latest version with the new files for the Customer to test and deploy.  

Customer uses a Third Party IT Provider/System Integrator to provide packaging

Cloudhouse Support will ask to be put in contact with the Third Party and discuss with them the best way forward to update the Compatibility Packages in alignment with their arrangement with the Customer.

Customer is out of support contract and has no packaging resource

Cloudhouse Support will offer to put the Customer in contact with a Cloudhouse Account manager, to either get them back on support or arrange for a chargeable Professional Services engagement to implement the update.

Risks, Limitations and Mitigation Actions 

Various issues may arise during the execution of this process. Here are a selection of potential problems and their mitigating actions: 

  • No response from Customer - All contact details Cloudhouse holds for the Customer are no longer valid. In this case, Cloudhouse Support will ask the Cloudhouse Account Director to gain new contacts via the commercial/procurement route. 
  • Compatibility Package held by Cloudhouse is out of date - Cloudhouse Support only retains details on the last Compatibility Package worked on. If a third-party has subsequently performed work on the Compatibility Package, the version data may be out of date. Once Cloudhouse is in contact with the Customer, the initial work will be to verify the current version of the Cloudhouse software the Customer has deployed and if it is affected.
  • Customer unwilling to update Compatibility Package - Cloudhouse cannot force a Customer to update a Compatibility Package. Cloudhouse will advise the Customer in writing that not updating is against Cloudhouse's recommendations.

Example Notification Email

Below is an example of an email we suggest using as the basis of the email to be sent to customers notifying them of a potential issue:

Dear Customer, XXX Personalised XXX 

Our records show you are a user of the Cloudhouse Compatibility Package software to enable XXX Application name XXX to work on a modern operating system.
