From a startup to a multinational corporation the software development industry is currently dominated by agile frameworks and product teams and as part of it DevOps strategies. It has been observed that during the implementation, security aspects are usually neglected or are at least not sufficient taken account of. It is often the case that standard safety requirements of the production environment are not utilized or applied to the build pipeline in the continuous integration environment with containerization or concrete docker. Therefore, the docker registry is often not secured which might result in the theft of the entire company’s source code.

The OWASP DevSecOps Maturity Model provides opportunities to harden DevOps strategies and shows how these can be prioritized.

With the help of DevOps strategies security can also be enhanced. For example, each component such as application libraries and operating system libraries in docker images can be tested for known vulnerabilities.

Attackers are intelligent and creative, equipped with new technologies and purpose. Under the guidance of the forward-looking DevSecOps Maturity Model, appropriate principles and measures are at hand implemented which counteract the attacks.


Go to

  • matrix shows the dimensions, subdimensions and activities are described.
  • Implementation Levels can be used to show the current implementation level by clicking on the specific activities which have been performed (it is recommended to use a gitops-like flow)
  • Mappings Shows mappings to other standards and provides the ability to download an excel sheet
  • Usage describes how to use DSOMM

In this video Timo Pagel describes different strategic approaches for your secure DevOps strategy. The use OWASP DSOMM in combination with OWASP SAMM is explained.

In case you have evidence or review questions to gather evidence, you can add the attribute "evidence" to an activity which will be attached to an activity to provide it to your CISO or your customer's CISO. You can switch on to show open TODO's for evidence by changing IS_SHOW_EVIDENCE_TODO to true 'bib.php' define(IS_SHOW_EVIDENCE_TODO, true);

In case you would like to perform a DevSecOps assessment, the following tools are available:

  • Usage of the applicaton in a container.
  • Development of an export to OWASP Maturity Models (recommended for assessments with a lot of teams)
  • Creation of your excel sheet (not recommended, you want to use DevOps, don't even try!)


  1. Install Docker
  2. Run docker pull wurstbrot/dsomm:latest && docker run --rm -p 8080:8080 wurstbrot/dsomm:latest
  3. Browse to http://localhost:8080 (on macOS and Windows browse to if you are using docker-machine instead of the native docker installation)

For customized DSOMM, take a look at In case you would like to have perform an assessment for multiple teams, iterate from port 8080 to 8XXX, depending of the size of your team.

You can download your current state from the circular headmap and mount it again via

wget # or go to /circular-heatmap and download edited yaml (bottom right)
docker run -p 8080:8080 -v /tmp/generated.yaml:/srv/assets/YAML/generated/generated.yaml wurstbrot/dsomm:latest


This approach also allows teams to perform self assessment with changes tracked in a repository.

Amazon EC2 Instance

  1. In the EC2 sidenav select Instances and click Launch Instance
  2. In Step 1: Choose an Amazon Machine Image (AMI) choose an Amazon Linux AMI or Amazon Linux 2 AMI
  3. In Step 3: Configure Instance Details unfold Advanced Details and copy the script below into User Data
  4. In Step 6: Configure Security Group add a Rule that opens port 80 for HTTP
  5. Launch your instance
  6. Browse to your instance's public DNS
service docker start
docker run -d -p 80:8080 wurstbrot/dsomm:latest

Activity Definitions

The definition of the activities are in the data-repository.

Teams and Groups

To customize these teams, you can create your own meta.yaml file with your unique team definitions.

Assessments within the framework can be based on either a team or a specific application, which can be referred to as the context. Depending on how you define the context or teams, you may want to group them together.

Here are a couple of examples to illustrate this, in breakers the DSOMM word:

  • Multiple applications (teams) can belong to a single overarching team (application).
  • Multiple teams (teams) can belong to a larger department (group).

Feel free to create your own meta.yaml file to tailor the framework to your specific needs and mount it in your environment (e.g. kubernetes or docker). Here is an example to start docker with customized meta.yaml:

# Customized meta.yaml
cp src/assets/YAML/meta.yaml .
docker run -v $(pwd)/meta.yaml:/srv/assets/YAML/meta.yaml -p 8080:8080 wurstbrot/dsomm

# Customized meta.yaml and generated.yaml
cp src/assets/YAML/meta.yaml .
cp $(pwd)/src/assets/YAML/generated/generated.yaml .
docker run -v  $(pwd)/meta.yaml:/srv/assets/YAML/meta.yaml -v $(pwd)/generated.yaml:/srv/assets/YAML/generated/generated.yaml -p 8080:8080 wurstbrot/dsomm

In the corresponding dimension YAMLs, use:

        Default: false
        C: true
        B: Showed Jenkinsfile
