2024 DevCentral MVP Announcement
Congratulations to the 2024 DevCentral MVPs! The DevCentral MVP Award is given annually to the outstanding group of experts in the technical F5 user community who go out of their way to engage with the user community. The award is our way of recognizing their significant contributions, because while all of our users collectively make DevCentral one of the top community sites around and a valuable resource for everyone, MVPs regularly go above and beyond in assisting fellow F5 practitioners by sharing their deep technical experience and knowledge. MVPs get badges in their DevCentral and Reddit profiles so everyone can see that they are recognized experts. They also receive MVP swag, and invitations to regular exclusive webinars and behind-the-scenes looks at things like roadmaps, new product sneak-previews, and innovative concepts in development at F5. DevCentral is grateful for and proud to recognise the technical knowledge and exemplary community engagement of these 43 outstanding community members: Amine_Kadimi Amr_Ali Austin_Geraci boneyard Bryan_T_ CA_Valli Daniel_Wolf Dario_Garrido Enes_Afsin_Al F5_Design_Engineer jaikumar_f5 Jim_Schwartzme1 JoseLabra JoshBecigneul Juergen_Mang Kai_Wilke KeesvandenBos Kevin_Davies Lidev lnxgeek LouisK Mayur_Sutare Michael_Saleem mihaic Mike757 Mohamed_Ahmed_Kansoh Mohamed_Salah_ Niels_van_Sluis Nikoolayy1 P_Kueppers Patrik_Jonsson Paulius PhatANhappy Philip_Jonsson PSFletchTheTek Rodolfo_Nützmann Samir ScottE Sebastian_Mani1 Sebastiansierra StephanManthey Tofunmi Whisperer2023 DevCentral MVP Announcement
Congratulations to the 2023 DevCentral MVPs! Without users who take time from their busy days to share their experience and knowledge for others, DevCentral couldn't be the helpful user community that it is today. To that end, the DevCentral MVP Award is given annually to the outstanding group of experts in the technical F5 user community who go out of their way to engage with the user community. The award is our way of recognizing their significant contributions, because while all of our users collectively make DevCentral one of the top community sites around and a valuable resource for everyone, MVPs regularly go above and beyond in assisting fellow F5 users. 2022 was tough in a lot of ways, and we are extra-grateful to this year's MVPs for taking the time and making the effort to help others. MVPs get badges in their DevCentral and Reddit profiles so everyone can see that they are recognized experts. This year’s MVPs will receive thank-you gifts, and invitations to regular exclusive webinars and behind-the-scenes looks at things like roadmaps, new product sneak-previews, and innovative concepts in development.

Hello DevCentral Community. Today I am launching our main community badge schema. 📛 I have been sitting on this for a while waiting - I can wait no longer. I hope this is a fun way for you to see what you have been up to on DevCentral, for others to see how many places you've been on DevCentral, and for us all to be digitally recognized for just how much we are helping each other; everyday. You can see badges you have earned by navigating to your own My Profile. At launch (today) - I have set the default email notification to be in a daily-digest. Tomorrow (July 19) I will set the notification back to immediately so you may be notified about badges as you earn them. Many are earned as you engage on the site but some can be earned while you are away. If you want to change the default you can do so in My Settings > Subscriptions & Notifications > Notification Settings. (linked for convenience) Some details. The badges follow a basic pattern with 8 achievement levels for each category. Levels 1 and 2 are visible whether you have achieved them or not, for each of the 10 initial categories. Each category has a different measure. For example, the count of comments to achieve level 4 (Comment-licious) will be different from the count of Kudos given to achieve level 4 (Kudo-licious) and the higher the level, in each category, the harder "the bosses" get. 😄 A very few members, notably JRahm, PSilva, and a few MVP's (who have been around and very active for many years) have reached level 7 or 8 in just a couple of categories but, for the most part, levels 5, 6, 7, and 8 are still wide open. There for the taking. Enjoy, have fun, and the last thing I'll say is I'm not done with badges; special badges, one-offs, and maybe even a whole new category (or three) will come later. Thanks for being part of our community. Lief * "Badges? We ain't got no badges! We don't need no badges! I don't have to show you any stinking badges!"Security Automation with F5 BIG-IP and Event Driven Ansible
Updated (September 19th 2023) INTRODUCTION TO EVENT DRIVEN SECURITY: Event Driven Security is one of the projects I have been working on for the last year or so. The idea of creating automated security that can react similarly to how I would react in situations is fascinating to me, and then comes the BIG Question.... "Can I code it?" Originally our solution we had utilized ELK (Elastic Logstash Kibana) where Elasticsearch was my logging and monitoring tool, Kibana was the frontend GUI for helping me visualize and set up my watchers for my webhook triggers, Logstash would be an intermediary to receive my webhooks to help me execute Ansible related code. While using Logstash, if the Ansible code was simple it had no issues, however when things got more complex (i.e., taking payloads from Elastic and feeding them through Logstash to my playbooks), I would sometimes get intermittent results. Some of this could be my lack of knowledge of the software but for me it needed to be simple! As I want to become more complex with my Event Driven Security, I needed a product that would follow those needs. And luckily in October 2022 that product was announced "Event Driven Ansible" it made it so I didn’t need Logstash anymore i could call Ansible related code directly, it even took in webhooks (JSON based) to trigger the code, so I was already half way there! CODE FOR EVENT DRIVEN SECURITY: So now I have setup the preface let’s get down to the good stuff! I have setup a GitHub repository for the code i have been testing with https://github.com/f5devcentral/f5-bd-ansible-eda-demo which is free for all to use and please feel free to take/fork/expand!!! There are some cool things worth noting in the code specifically the transformation of the watch code into something usable in playbooks. This code will take all the times the watcher finds a match in its filter and then then copies the Source IP from that code and puts it into a CSV list, then it sends the list as a variable within the webhook along with the message to execute the code. Here is the code I am mentioning above about transforming and sending the payloads in an elastic watcher. See the Full code in the GitHub repo. (Github Repo --> elastic --> watch_blocked_ips.json) "actions": { "logstash_exec": { "transform": { "script": { "source": """ def hits = ctx.payload.hits.hits; def transform = ''; for (hit in hits) { transform += hit._source.src_ip; transform += ', ' } return transform; """, "lang": "painless" } }, "webhook": { "scheme": "http", "host": "10.1.1.12", "port": 5000, "method": "post", "path": "/endpoint", "params": {}, "headers": {}, "body": """{ "message": "Ansible Please Block Some IPs", "payload": "{{ctx.payload._value}}" }""" } } } } In the Ansible Rulebook the big thing to note is that from the Pre-GA code (which was all CLI ansible-rulebook based) to the GA version (EDA GUI) rulebooks now are setup to call Ansible Automation Platform (AAP) templates. In the code below you can see that its looking for an existing template "Block IPs" in the organization "Default" to be able to run correctly. (Github Repo --> rulebooks --> webhook-block-ips.yaml) --- - name: Listen for events on a webhook hosts: all ## Define our source for events sources: - ansible.eda.webhook: host: 0.0.0.0 port: 5000 ## Define the conditions we are looking for rules: - name: Block IPs condition: event.payload.message == "Ansible Please Block Some IPs" action: run_job_template: name: "Block IPs" organization: "Default" This shows my template setup in Ansible Automation Platform 2.4.x, there is one CRITICAL piece of information i wanted to share about using EDA GA and AAP 2.4 code is that within the template you MUST tick the checkbox on the "Prompt on launch" in the "variables section". This will allow the payload from EDA (given to it from Elastic) to pass on to the playbook. In the Playbook you can see how we extract the payload from the event using the ansible_eda variable, this allows us to pull in the event we were sent from Elastic to Event Driven Ansible and then sent to the Ansible Automation Platform template to narrow down the specific fields we needed (Message and Payload) from there we create an array from that payload so we can pass it along to our F5 code to start adding Blocked IPs to the WAF Policy. (Github Repo --> playbooks --> block-ips.yaml) --- - name: ASM Policy Update with Blocked IPs hosts: lb connection: local gather_facts: false vars: Blocked_IPs_Events: "{{ ansible_eda.event.payload }}" F5_VIP_Name: VS_WEB F5_VIP_Port: "80" F5_Admin_Port: "443" ASM_Policy_Name: "WAF-POLICY" ASM_Policy_Directory: "/tmp/f5/" ASM_Policy_File: "WAF-POLICY.xml" tasks: - name: Setup provider ansible.builtin.set_fact: provider: server: "{{ ansible_host }}" user: "{{ ansible_user }}" password: "{{ ansible_password }}" server_port: "{{ F5_Admin_Port }}" validate_certs: "no" - name: Blocked IP Events From EDA debug: msg: "{{ Blocked_IPs_Events.payload }}" - name: Create Array from BlockedIPs ansible.builtin.set_fact: Blocked_IPs: "{{ Blocked_IPs_Events.payload.split(', ') }}" when: Blocked_IPs_Events is defined - name: Remove Last Object from Array which is empty array object ansible.builtin.set_fact: Blocked_IPs: "{{ Blocked_IPs[:-1] }}" when: Blocked_IPs_Events is defined ... All of this combined, creates a well-oiled setup that looks like the following diagram below, with the code and the flows setup we can now create proactive event based security! Here is the flow of the code that is in the GitHub repo when executed. The F5 BIG-IP is pushing all the monitoring logs to Elastic. Elastic is taking all that data and storing it while utilizing a watcher with its filters and criteria, The Watcher finds something that matches its criteria and sends the webhook with payload to Event Driven Ansible. Event Driven Ansible's Rulebook triggers and calls a template within Ansible Automation Platform and sends along the payload given to it from Elastic. Ansible Automation Platforms Template executes a playbook to secure the F5 BIG-IP using the payload given to it from EDA (originally from Elastic). In the End we go Full Circle, starting from the F5 BIG-IP and ending at the F5 BIG-IP!

Tuesday, May 24th marks the first DCC for me to be an "official" cast member! I'm taking over the vacant chair left by Mr. John Wagnon, as our DCC security specialist. Having seen John in the community for years and years, it seems like a daunting task, but I've got some great people to learn from, for sure. Back in 2008 or so, I was introduced to F5 as a customer and, at the time, was very much an Open Source zealot. I shied away from purchasing anything at all besides servers to run Linux on. I was truly moved by F5's community website and began my transition to becoming an F5 zealot when I found this gem of an article that comletely changed the health and performance of my massive scale SaaS implementation. It's awesome to have my first livestream be a Top5, as the crew had me test out my chops with a Top5 for March: It was the first thing I did in my new home studio, though, so I had to come to grips with moving on from my old Blue Yeti mic and get down to business with a spare Shure SM-57 I had from my snare drum. I'm truly honored to join this cast of characters, buulam, JRahm & PSilva and will work to deliver the best community focused security content possible.Ch-ch-ch-ch-changes
Hi everyone, welcome to the new DevCentral! If you are reading this, there’s a good chance you have noticed some big changes to the site. This article will go over some of the changes, get you started, and introduce some of our new features. Another platform change? Why? Those of you who've been around a while know that the last major site change didn’t work out as we’d hoped for a variety of reasons. It has taken a while for us to prepare a solid fix, and we appreciate your patience and assistance in the process. In our ongoing effort to serve the DevCentral community as best we can, we’re proud to announce the launch of our new and improved site. What does this mean for me? For most users, you’ll simply need to adjust to the renovation and have fun exploring the new features we’re all excited about. A few of you may want to make some changes to your username or profile. OK, so what changed? TL;dr - you can skip on over to the Getting Started guide if you don't want to read through the changes listed below. Usernames: Spaces in usernames are not available going forward, and existing spaces in usernames have all been converted to underscores. For example, my old username “Leslie Hubertus” is now “Leslie_Hubertus” – and while everyone now has the option of changing their username, please note that spaces are no longer allowed. Additionally, if you had a really long handle (16+ characters), it has automatically been truncated to 15 characters. The system will automatically prompt you to update your username the first time you log in. You can leave it truncated if you wish, or change it at that time. If you decide to change your username , you can do so at any time by clicking on your profile picture in the top right of your screen, and clicking on My Settings. This will change the username associated with your profile and all your posts. Ranks: Our ranking schema has gone cloudy and we have added a few levels. You'll see everyone's rank next to their username. A quick note: 2 ranks override point-based ranking: MVP, and F5 employee. Do you have what it takes to get to Bespin? More info to come. Where did everything go? TL;dr Questions is now FORUMS Articles is now TECHNICAL ARTICLES CodeShare is now under the CrowdSRC umbrella Article Series can now be found by searching for "series," and we will be publishing an article with more information in days to come (and update this and the Getting Started articles accordingly). Questions has now become FORUMS: Technical Forum This is where you’ll post any technical questions or observations, just like you would have in the old Questions section. Water Cooler This is a new feature where the community can post about anything else (within the community guidelines). Want to talk about a particular Agility session, or general trending non-political news topics? Brag about your sweet home rig, or get advice on building one? This is the place to do that. Note: Posts, kudos, and comments in the Water Cooler do not count towards your rank – but good content is good content. When really good stuff happens around the Water Cooler we may move it to make it more prominent. Articles: Technical Articles This is where you will find, well, technical articles...go figure! These articles are written by F5ers, just like before. CrowdSRC This is dedicated to community-created and -contributed technical articles and code. It is a new and improved version of the old CodeShare. Code is of course still welcome and encouraged, but you can now also write free-form insights and solutions to share with the community. Note that the DevCentral team will review submissions prior to publishing, and all are subject to the community guidelines. DevCentral News This is a new featured section where you’ll find announcements, and other non-technical information from the team. Check here for Agility updates, contest announcements, team updates, and swag giveaways. Groups: This is a new feature we are excited about! Groups is a place for special groups to have conversations. The inaugural group is the MVP group, which is an invite-only place for our MVP cohort to converse with each other. We will be opening this feature to other groups slowly as we come to understand whether it serves the community well, For example, there may be potential for usergroups to have their own space in the community. We would love to hear what you think about the Groups feature. Events: This is another new feature we are excited about! This is where you’ll find links to things like Agility, webinars, trivia games, SME office hours, Livestream after-hour shows, and other events we’re planning for the community. Suggestions: Code syntax highlighting is now supported! Thanks to @MVP Kevin Davies for suggesting this feature! Whether you are creating an article or making a comment, here’s how to insert code: Click on the three dots to expand the toolbar: Click on Insert/Edit code sample, and you will see the following popup: OK, but what happened to my Follows, Bookmarks, and Private Messages? Unfortunately, we weren’t able to migrate this information on your behalf. Please read this article for more information. If you didn’t get notification about this ahead of time, and really need the name of that one article you rely on, please reach out to us at DevCentralFeedback@f5.com and someone on the team will reply directly to you. Unfortunately, while Private Messages continue to be a feature, we were not able to keep Private Message data across the migration. Follow is now Subscribe. How do I Subscribe to (formerly “Follow”) or Bookmark an article? Once you are in an article, you’ll see And At the top of each article, there are two options available to you. You can click on the small drop-down arrow or use the Options link with the three vertical dots. Once you do, you will see the menus as shown, where you can Bookmark (saved to a list on your profile) and Subscribe (get notified of article updates). How do I manage Bookmarks and Subscriptions? Click on your avatar in the top right of the page, then click on My Subscriptions, and it’ll take you directly to the relevant part of your My Settings page where you can Customize All The Things (related to your notification settings): Customize your experience! How do I find that article I really liked? Labels and Tags on this platform: Labels are enforced on new content and represent a very small set-list of high-level organization defined by us: Security, DevOps, Application Delivery etc. Tags are those free-form pieces that the author may contribute to their own post. You can interact with these components like this: (added tags are clickable/sortable too) You can subscribe to changes for any label (when you click on it) And you can see articles sorted by tags by clicking on them too. The red bar at the left of a post marks UNREAD. Important note on subscribing to tags: Subscribing to a tag is board specific, so if you want to see (for example) irules in articles and technical forum, you need to subscribe in both places. Fine, fine, but... How do I post a question, comment, or code? Please read this article for a primer on posting to the new DevCentral. Besides the editor being fairly intuitive, consistent, and easy to use, one new thing we’re happy about is that copying and pasting from into the text editor should no longer result in failarious formatting issues. You should also be able to write in multiple coding syntaxes now, including GO, ApacheConf, TCL, and nginx Guideslines and EULA, oh my Here are the DevCentral Community Guidelines, and this is our updated EULA. I’m still reading this. What's next, and where’s my cookie? We’re glad you stuck with us this long, and really hope you are happy with the changes. We do have more incremental changes planned, will be making further improvements as we go, and hope you will leave us a comment below or use the Suggestions page to share your input! As for cookies, well… that’s between you and your browser history.DevCentral's Featured Member for January - Daniel Wolf
Our Featured Member series is a way for us to show appreciation and highlight active contributors in our community. Communities thrive on interaction and our Featured Series gives you some insight on some of our most engaged folks. DevCentral Member and newly minted MVP Daniel Wolf is our Featured Member to kick off 2022! Let's catch up with Daniel! DevCentral: First, please explain to the DC community a little about yourself, what you do and why it is important. Daniel: I’m an enthusiast. When I was younger, I was a passionate handball player. Later I also became a passionate handball coach for children. Recently I became an avid cook. Almost ten years ago I moved to the Balkans, to the city of Skopje. I fell in love with the region, the people, and the Balkan way of life. I even found my wife there. Almost three years ago my family and I moved back to my hometown, a small city close to Frankfurt in Germany. And I have always been a tech enthusiast. DevCentral: You’ve continued to be an active contributor in the DevCentral community. What keeps you involved? Daniel: I find it interesting to read what challenges others from the community are facing. In case I know an answer to their question, I will reply. In case I don’t know the answer, but I think I can figure it out with a reasonable effort, I will try to. It helps me to broaden my knowledge but even more important to share the answers with others. DevCentral: Tell us a little about the technical expertise you have. Daniel: First time I touched a computer was an Intel 286 with DOS 5.0. After a couple of weeks, I deleted a couple of seemingly useless file to install Monkey Island. Since then, I became pretty good at solving computer problems. Nowadays they are called projects and the problems are often much more complex. The last technology I was responsible before I decided to become an F5 consultant was Microsoft SharePoint and other .NET web apps. Roughly 7 years ago, there was a project to protect an online banking application with a WAF. So, unlike many other F5 specialists, I am not a network specialist but a web server dude. DevCentral: You are a Senior Network Professional at Controlware GmbH. Can you describe your typical workday, how you manage work/life balance and the strong support of F5 solutions? How has the pandemic impacted your work? Daniel: I appreciate that there is not a typical workday. I enjoy a challenging mix between projects, presales activities and occasional L3 support. Most fun for me are projects where I can help my customers to protect their apps and APIs. In the past two years we also had a lot of projects building, improving, or scaling out identity-aware access solutions. So, on a typical day, I’d say I am still solving computer problems. The pandemic has improved my work/life balance, I don’t have to drive to the office anymore and I can have a walk in the field during lunchtime or enjoy a coffee with my wife (she’s also working from home). DevCentral: Do you have any F5 Certifications? If so, why are these important to you and how have they helped with your career? Daniel: I have the 401 since last year. The 401 was a very good exam, passing it required an understanding of many F5 solutions but also of broader security concepts. My employer is promoting to get certified and allowed me to prepare during working hours. DevCentral: Describe one of your biggest Customer challenges and how the community helped in that situation. Daniel: I’d say that this is one of my current projects. We are migrating from an end-of-life proxy platform to BIG-IP and we are building a lot of the content switching and rewrite features with iRules. Devcentral is a goldmine if you are looking for iRule documentation and code snippets. DevCentral: Lastly, if you weren’t doing what you’re doing – what would be your dream career? Like, when you were a kid – what did you want to be when you grew up? Daniel: I always wanted to be some sort of IT guy. I think I am fine where I am now, I enjoy my work. If I was granted a wish, carpenter would be an alternative. I like the idea that, at the end of each day, you can see what you have built with your own hands. The things I build, they are meaningful as long as there is a browser available. ---Thanks Dan! We really appreciate your willingness to share with the DevCentral Community.
