About the session
DevSecOps assessments are performed often only quarterly/yearly/by-yearly. If you want to provide fast feedback to your teams about their maturity, this is for you!
- New Features from GSoC
- New Features (e.g. team assessments)
- Outlook of the Metric Collector and Analyzer
Dinis Cruz - 00:05 Welcome to the open security summit session where we have Timo, a longtime participant in Prakash, also participating here amazingly. And they’re going to be talking about DevSecOps maturity model. So over to sorry, it is DevSecOps, right? Or is this yeah, it’s DevSecOps with TT model. Sorry, I flipped for a second. Off you go.
Timo Pagel - 00:33 Cool. Hey everyone. So I am Prakash Gupta, and I’ll be walking you through the DSOM updates. And we’ll also talk about the new features as well as the outlook of our DSOM. We have Prakash Gupta as well as team of pages for this whole presentation. So before we begin, let me just give you a brief introduction about myself. I have been working on DSOM for the past three to four months as part of my Google Summer of code contributions. Apart from this, I am also a software engineer at Expedia Group. Well, about Timo pagel, I think you already know he’s a well known speaker at OSS. So we can move on. So let’s talk about the agenda which we have over for our DSOM presentation.
Timo Pagel - 01:20 We’ll start with the new features from Google summer of code which is going to be covered by Prakash which is me. And then we have new features apart from Google summer of code as well as the outlook of our DSOM which is going to be covered by demo. So let’s start with our new features from Google summer of code. So on the first list we have activity tag filter. Now before explaining to you the slide, let me just give you a brief demo about it. So this is our newly revamped DSO. And as you can see here, we have a sub dimension filter which was previously present and which used to have deletable chips before. So you can see we have refreshed this chip set. We have now toggle switches which can be turned on and off depending on the user choice.
Timo Pagel - 02:10 And we have now included a tag section under an activity. So as you can see inside our matrix we have process as a tag for an activity. We have artifacts, we have components. We also have none for different activities. Now here you can see that we have now integrated an activity tag filter which is dependent on these tags which we have now defined. So these tags for example, if a user if I am the user and I just want to see the activities which does not have artifacts, so I can just click on artifacts and all the activities which does not have artifacts are going to be removed and I can only see the activities which are turned on in the activity tag filter. Now having all these chips can be a cumbersome approach.
Timo Pagel - 03:02 So we have also added a reset button so that user can directly see the default view of the matrix. So this is about the activity tag filter. I’m sorry, if anyone has any doubt, please feel free to interrupt me in between and we can take that out right here. So instead of having deletable chips, we have implemented our toggle switches. We have also added tags into our activities and we have now created another activity tag filter which you can see right here. We don’t need to see the demo here. Move on. So this is the second part of our GSA contributions. So overlay for activity view. Now previously into our implementation levels we used to have all these activities.
Timo Pagel - 03:58 We used to have all these activities and when a user wanted to know about the activity and they used to click on it, a different page used to open up right here which used to kind of break the user workflow. So instead of that we have defined an I icon here. So when the user clicks on that I icon they can see the details of the activity as part of an overlay. It’s just right there. It does not break the user workflow. It’s already present in the top you can see it’s, the dimension of that activity. We have the subdimension and then we have the activity name and we have all these parameters of these activities. We have also included the tags. If the user want to know which all tags fall under that activity, we have also done that.
Timo Pagel - 04:46 So these are all the activities which are here. This is the part of overlay. To open the overlay we can click on the I icon which is going to be present along all the activities. The right hand side. Cool. So this is about overlay. Let’s move on. Move on to the teams is. I think this is going to be the major part of the Google summar of code contributions. We have included two different concepts, team and team groups. So previously the whole DSOM was created on a single user approach. Now we have included teams and team groups into this. So into the menu bar when you can see a teams title here, when we click over it we have a list of teams. So these are all the teams which are present by default. The user can change it in the YAML file here.
Timo Pagel - 05:46 So we have three teams right now default, B and C. So these are all the team list. Now about the team groups can have multiple teams under them. So it works like a department for them. So we have three team groups here. We have group A, we have group B and we have group C. So in the group A we have default and B. In the group B we have team B and team C. And then in the group C we have team Default and team C. So this is teams component. I’m going to show you what this actually makes sense. Why I don’t think that without even having to be able to utilize teams it is going to make any sense. So this is the part team based assessment. Now, when we go over to the implementation levels we have multiple things.
Timo Pagel - 06:37 Here we have on the right hand side you can see Team Filter here, default PNC. And for all the activities we can define which all teams have to complete that particular task. So for example, if I open up in the level one of build, we have this defined build across this activity. Now this particular activity needs to be completed by all the teams A and teams A, B and C. Now only Team C has completed it. So this particular cell has been colored 33%, which is one by three. So for example, if a team B decides to complete the particular task, they can click on it and the color is going to depend on that. Now we have default B and C as a team filter. So for example, I only want to see the progress of B and C.
Timo Pagel - 07:29 So this is the second part of our team based assessment. We have included team filters into our implementation levels. So now if the user wants to see the progress of only Team B and Team C, they can easily see that by deselecting default. So now only team B and C, the progress of Team B and C is visible here. If I deselect this, if I deselect A, B and C it is going to get colorless and even if I select A it’s not going to make any difference because we are only viewing the progress of Team B and Team C. Now this is the team filter. Now we also introduced team groups here in the teams component. So what team group means is we can preselect different teams here. So for example, we have default and B in the group A.
Timo Pagel - 08:25 If I want to see the progress of B and C I can go for group B and similarly for group C we have default and C. So now these groups can be predefined by the user depending on what is the size of their department, what all members are working on under them. So it makes it very easier for the user to see the progress of particular departments rather than seeing the progress as a whole of the company. In a team based assessment you can see that for every activity we have multiple teams, team A, B and C. We have all the checkboxes. The user can click on these checkboxes to mark that this particular team has completed this particular task. As I discussed, we have integrated team filter as well as team Group Filter into this.
Timo Pagel - 09:14 So this marks the information about Team Pace assessment. If anyone has any doubts under it, we can discuss it right here. Else we can move on to the new features apart from GSOC. Timo, would you like to take the stage?
Prakarsh Gupta - 09:40 Give me a second to do so. Maybe you can stop. I can take over. So now you should see my screen and I go on. I will quickly present new features which we have in addition to the features from Prakash. And afterwards we will have an outlook. That outlook will be a bit longer because I will tell you the architecture of Metrica and afterwards we will hear about enhancing vulnerability management. Yeah. So actually Denise last year requested that we have IDs for the activities in the DevSec optimal duty model to be able to reference to these IDs. And that is now implemented. What is missing is that it’s part of the Ul. In the Ul, it’s still the name of an activity which you could implement but that will come one day. We have also other model changes.
Prakarsh Gupta - 10:57 For example, a big break is that we move from four levels to five levels. We have new either 2001 mappings and we have a fix of spelling errors. Now I would like to move on to Metrica. So a problem which I often see is that assessments are done from time to time. Maybe once in a year, maybe only every two years. And as a product team I want fast feedback. So I get the feedback. I haven’t implemented something and when I implement it I want to see the changes reflected in the maturity model. And that is so far very hard to reach. And I saw that in a lot of organizations that I think that will enhance security contributions. Because when the next audit is next year, so that’s far away until it’s there and then there’s not enough time to fix something.
Prakarsh Gupta - 12:09 So I think it’s very good. When you did something, you get the fast feedback like you want to have in DevOps. I have two steps. One is to have manual assessments which you can place in YAMLs. And then in addition to automate the collection from different sources here we see an overview of the architecture. You see on the bottom are YAML. So you have activities where you can fill out. As a product owner I did this activity, or as a team member I did this activity. For this application. For example, we can for example have threat modelings performed. So we document in YAML we have performed the threat modeling for that and that application. And then Metrica can process that and show it in the Grafana dashboard. And if you want, you can also send out alerts.
Prakarsh Gupta - 13:14 For example, if your threshold is two thread more links in a year, but there’s only one for a specific application, then you can send out an alert with the Grafana tools. All I’m telling you right now is just the draft so everything can be changed. We’re in the design phase. So in case you recognize something where you say that I would do different, please tell me. So right now it’s very easy to change everything. But we will actually start next week to code. Right now is the time to give feedback. And the alternative to YAMLs for threat modeling feels a bit like extra work because what you do in threat modeling normally is to document it. You document and confluence parts of the threat modeling. The diagram, for example.
Prakarsh Gupta - 14:07 So there is the source which you can ask is the threat modeling performed to a very specific team in case you do it in a structured way. For example, you have a header where you say team members and you have a header where you say for which application ID or deployment ID or whatever IDs you use to identify your applications. And when you have it in a bit structured format, you can ask Confluence or any other wiki. Is there, is threat modeling documented already? And then the collector can pick it up through the API in terms of Confluence and then you can check thresholds again and put it in Grafana security dashboards. So that is the main idea here. I don’t see any questions. Let me see if I can open the chat so that yeah, so no, so far no questions.
Prakarsh Gupta - 15:05 So I will now dig a bit deeper so you get a better understanding of it. So this is how I envision what I also have seen already in different companies, that you have an application YAML for example, and a teams YAML for application specific activities. And then you have a team YAML in a folder, in the teams folder in Git, and all activities from the team inherit to the application. So an activity which is team based is, for example, a security champion. Does this team has a security champion? And in case, yes, it inherits to all applications of that team. So let us stick to the threat modeling example. So the product owner right now changes the application YAML adds threat modeling, adds a link to the threat modeling in this case because it’s currently not automated.
Prakarsh Gupta - 16:09 Then the product owner pushes the changes to a Git repository under the control of the executive team of that organization, and then the product owner creates a PL for this change. Afterwards the security architect can review this and approves or denies, for example, the security architect could perform a check if the link to that documentation is accessible for the security architect, or he or she can review the threat modeling if it’s sufficient. And then you can show the changes on a security dashboard. Now we dig a bit more in the architecture and in order to be able to zoom, I use draw I over here directly. So in Git we use GitHub as our source repository and our build platform. And in GitHub, let us start in the middle.
Prakarsh Gupta - 17:23 Here we will build the needed components like a statistic generation module, the collector and Grafana dashboard. I will tell you afterwards why that is needed. And then in addition to GitHub.com, we have the organizational space that is all this here in the middle, where the organization might want to overwrite the default activities or the maturity model definition, which activities are 1 second, I need to go back. It all happens here in this right part, what I said so far, you define the activities for your maturity model and on the left you see what activities has been implemented by the teams for which application. Then you combine these data and then you can check thresholds as an alternative to the YAMLs. We can also use the collector. One example might be your security vulnerability scanners which you might utilize.
Prakarsh Gupta - 18:24 And there, for example, you use contrast security checkmarks veracode, the defect ojo, whatever you use from that we can grab the meantime to resolve, for example. And then we can later show it in the dashboard here. As I said, we think about here on the right to utilize Grafana. A problem with grafana which I see is that we would need to create a Grafana default dashboard which will not fit to the thresholds which you have defined here beforehand. So we thought about how can we utilize that. And so far the idea is to use templating. So we have here a grafana dashboard application, which we use to create in the end grafana dashboards out of the data we have defined here for the activities, and then we can populate this dashboard to grafana.
Prakarsh Gupta - 19:41 In addition, when we have a data points, whenever something changes might be the collector picks up daily the meantime to response from the teams, or we have a change here in one of the activities, for example, I performed the thread modeling, so there will be a new date for thread modeling. Then we push through prometheus push gateway these metric data, so we have a new time point in the time series database and then we can utilize this data from Grafana. In addition, when we have the definition of thresholds already here, we can also more easily export data at this point in time. So we can, for example, use a transformation to be able to show the activities which we have performed also in the DevSec Optimity model per team.
Timo Pagel - 20:51 All right.
Prakarsh Gupta - 20:56 I go back. I have to add it’s not a silver poop bullet, because still people need to perform threat modelings, right? So people and processes is a thing you really need to tackle. It just enables you to do it in a better way. From my point of view, people still need to understand that they update these YAML files, otherwise they will get alerts, for example. But maybe they create a filter and route the alerts and spam box. So you need to have work to cultural work to let people understand why they have to do it. That is something you cannot outsource. But I think it’s really helpful to enhance your culture. Yeah, it’s still a draft. It’s done when it’s done. Currently we think it will be done by the end of this year.
Prakarsh Gupta - 21:57 Please contact us in Slack and the dsound Channel or contact us via GitHub issues. Maybe I should show here that there is a Git repository for it that you find here. That’s also a change. Beforehand. The DevSecOps Maturity model repository was under my name. Now you see, it’s under DevSecOps maturity, model, organization. And we have here Metrica. And in Metrica currently, as you see, we only have documentation. We just have documentations about the architecture. We have architecture decision records here. So for the YAML we have defined here how these YAMLs are structured. This is the one the teams fills out or the product owner fills out for his applications. So we have here an API version, a Kind, and then application settings. And then we start with the activities. And here’s, for example, conduction of threat rolling on technical level.
Prakarsh Gupta - 23:09 As I said, very important is that we have a date so we know when it happens. Currently I haven’t planned that we have quality criteria or something. So you just have a title and then you might have links later. As I said, it would be very good to automate this because in case you just have a small structure how to document a threat model, you can grab that information and then you have other activities here like data privacy requirements. It’s just a read confirmation or that there is Source Control protection enabled. This is something currently we plan to have it first in YAML files, but later obviously you can go to your version Control system platform like GitHub, utilize the API and check the configuration of all your repositories. So the teams don’t have to do that manually in here.
Prakarsh Gupta - 24:06 But this kind of checklist is the start and then we enhance it to automate it more and more. I should also mention the sponsors. So currently I am building this with Access Switzerland. So they are the main driver of this. They are also sponsoring development resources. But obviously we hope that by making it open source that other people will join and contribute different features. Go back to the diagram. For example. Everything I marked blue here will likely not be sponsored by Access. So tools like Defect Ojo for example, will likely not be sponsored by Access Switzerland. So that is something where we could need help. Or also here the team’s communication currently is not planned or other exports.
Prakarsh Gupta - 25:08 Exports mean that when there is an alert, for example that you haven’t performed threat modeling within the last year, then you might want to have it in your Vulnerability management system or in your incident management system, depending what you’re utilizing there and then you have there in the finding. All right, let me go down a bit to the definition. So this is what you document as a product owner. Now let us come to what you document as a security architect for your maturity model. Here is an example for production of simple threat modeling on technical level. Then you can define components. For example that there should be an array with a title inside with an object title which is string, a date as a date and again an array for a title as a string and a URL as a URL.
Prakarsh Gupta - 26:09 Then you have the level so your desired level in your application security maturity model and then the threshold. So the threshold here is a date. There should be ten dates for the last 365 days. So that is very optimistic. I would say ten thread warnings for one application but that is how you can define it. You can also reduce the value here in case you think ten is too, less or too much. Then we also want to populate that data to grafana. So you can define the diagram type as a chart and you can add grafana information mainly no, I think in case you have diagram chart here, you don’t need this information. This all comes from the top here. Oh, I didn’t push this. I changed it, but I didn’t push. Yeah, okay.
Prakarsh Gupta - 27:12 I am currently not sure if it’s the right way to do it so generic, so that you can really combine everything you want. That makes it a bit more complex in the development process, makes it very adjustable later for organizations. That’s why we defined it like this. But on the other hand, sometimes it’s better to just define in Java, threat modeling is like this and don’t let you define all this. But we said it’s better to have this very generic. Then we pick it up and you can define your own activities because everyone will define these activities different. At least there will be different names and you have different sessions, different attributes you want to ask for.
Prakarsh Gupta - 27:58 So that’s why we make it so generic and then out of this we can generate a schema definition so that when a product owner will update the YAML, it will directly tell you if that YAML is conformed to the schema. So far I don’t see questions in the chat so I will continue to talk. I think here we mostly saw everything which is important. Now maybe this here is also nice, the required level. So you saw in the definition of your maturity activities you need to define a level and in that level you can define for example, you want to have a pen test by yearly and a pen test yearly on your level three. On level one you don’t have a pen test because it’s internally. That’s something I saw very often in different organizations.
Prakarsh Gupta - 29:06 And like that you can also because you have these pen tests two times, you can define applications on level two should perform the pen test every two years and on level three every year. So you have different thresholds for these two different activities. Okay, yeah, we thought a lot about what should be the dashboard. As I said, in the end we came up with Grafana because we need something where we can show metric data and we thought about creating our own dashboard using DSIM as a dashboard or using Grafana. And Grafana is currently the best option, I would say. But with the extension that here, we can also transform the data which we have here and add it to our DevSec ops maturity model. All right, I think that’s all I can tell you right now.
Prakarsh Gupta - 30:30 In case you have any questions, please do not hesitate to ask. I’m also open for calls in case you want to have an extra call. I think recurrently, you are not allowed to talk, so you would need to write in case you want to talk. Maybe we can enable you to talk. So just ask me here or ask me later. Now we come to the last update, that is that we currently work on the merge with the vulnerability management framework. Francesco Meker is the author of this vulnerability management framework. We performed so far a mapping. We defined what we need, so he said he really needs five dimensions. So that was five levels. That was a kickoff that I moved from four to five dimensions. I wanted to do this since long, but now it’s implemented.
Prakarsh Gupta - 31:28 Also we said we need different tags, so that’s why. Also we implemented the tax feature currently based on all activities, the non tag in the production version. But we will change that soon. All right, so this is the end of this talk. Do you have any questions? One addition maybe. Denise in the start asked me about how can we make it more accessible that people can ask I have this problem and see the answer, for example, from the DevSecOps maturity model without the need to go through all the different activities. I’m working here together with Spiros, with the Open CRE project, which from my understanding means they will grab the data from the YAML or from the application, and then they have an AI where you can ask questions and it will point you to the different Ovas projects.
Prakarsh Gupta - 33:02 And one project I think in the future will be the DevSecOps maturity model. Oh, we have a question here. First question. These are model changes from four to five levels and some other additions. Do you expect changes to the model from time to time? So these hard changes I don’t expect often from four to five levels, that will not happen. I assume currently that won’t happen in the next two years. That was just because we had too many activities. In case we now get an activity boom and we get, let’s say, 50 new activities, we will have to think about more levels. But I don’t see that currently that we will get a lot more activities, that we need more levels.
Prakarsh Gupta - 33:44 You need more levels when you have too many activities in one let me open it so I can show it in one subdimension and level so you can see it better when I show it. So when you have let me find something. Where we have a lot here, for example. So infrastructure hardening we have here a lot of activities so the maturity model is there to guide you what you have to do as a next step. But here this field is already like a bit too much. Here this is only here so much because I have to not only relate all the activities in this subdimension, I also have to take a look. What? Do you do in all the other subdimensions? And then I have to place it according to that and not according only to this subdimension.
Prakarsh Gupta - 34:37 It’s why you have so many activities here. And now you have to choose again, right? What do I do first of all of this? Why? The objective of the model is to give you a guideline that’s why we now have five but you see still this one here has a bit too much but all the others are looking fine, right? So there it’s acceptable only this has the match so I don’t expect so big changes in the future do you have more questions? Okay, I stopped the recording hi at least I hope I can do that the recording now is not stopped do you want to copy to cloud recording? If yes, you will see an email notification when the cloud recording is ready.
