For almost two years Niels van Sluis has worked as a Security Engineer for Vosko Networking. Vosko’s security team focuses on supporting security solutions from various vendors like F5, Check Point, Cisco and RSA. Niels focuses is on F5 BIG-IP and Check Point. He started his professional career about 20 years ago in the ISP industry as an Unix Administrator, and switched to the public healthcare sector around 2001. In more recent years, he’s moved more towards working on network security and design. Apparently, having a Unix background helps a lot when working with modern security devices, since most of them are running on some flavor of Unix. When not working or spending time on DevCentral, he likes to travel, visit historic places and enjoy nature. And Niels is DevCentral’s Featured Member for July!

I’ve Successfully Failed the F5 Certification 201-TMOS Administration Exam

Yup, you read that right. I did not pass the F5 Certified BIG-IP Administrator test I took while at F5 Agility 2017. And I’m not ashamed since it was a challenging test and I will be trying again. Sure, I went through Eric Mitchell’s (F5er) comprehensive 201 Certification Study Guide along with the TMOS Administration Exam Blueprint. However, I probably should have taken more time ON a BIG-IP messing around…especially for tmsh commands…which is where, I believe, I got tripped up. This is key. Reading and memorizing commands along with some practicing can only get you so far. Doing it regularly is what’s needed. This is a key feature of the exams, particularly as you move up the exam expertise. The exams are designed to test real knowledge and experience, not if you can cram the night before. Pretty sure my errors came with tmsh and the UCS upgrade questions since I ... (more)

BIG-IP VE on Google Cloud Platform

Hot off Cloud Month, let’s look at how to deploy BIG-IP Virtual Edition on the Google Cloud Platform. This is a simple single-NIC, single IP deployment, which means that both management traffic and data traffic are going through the same NIC and are accessible with the same IP address. Before you can create this deployment, you need a license from F5. You can also get a trial license here. Also, we’re using BIG-IP VE version 13.0.0 HF2 EHF3 for this example. Alright, let’s get started. Open the console, go to Cloud Launcher and search for F5. Pick the version you want. Now click Launch on Compute Engine. I’m going to change the name so the VM is easier to find… For everything else, I’ll leave the defaults. And then down under firewall, if these ports aren’t already open on your network, you can open 22, which you need so you can use SSH to connect to the inst... (more)

What Is #MQTT? | @ThingsExpo #IoT #M2M #RTC #DigitalTransformation

The mad dash to connect virtually every noun to the internet or the Internet of Things is creating a massive M2M network for all the devices, systems, sensors and actuators to connect & communicate on the Internet. With that, they need a communications protocol to understand each other. One of those is Message Queue Telemetry Transport (MQTT). MQTT is a “subscribe and publish” messaging protocol designed for lightweight machine-to-machine (or IoT) communications. In this episode of Lightboard Lessons, I light up how MQTT works. ps Related: IoT Ready Infrastructure IoT Effect on Applications IoT Influence on Society What are These "Things?

Updating an Auto-Scaled BIG-IP VE WAF in AWS

Update servers while continuing to process application traffic. Recently we’ve been showing how to deploy BIG-IP (and F5 WAF) in various clouds like Azure and AWS. Today, we’ll take a look at how to update an AWS auto-scaled BIG-IP VE web application firewall (WAF) that was initially created by using this F5 github template. This solution implements auto-scaling of BIG-IP Virtual Edition (VE) Web Application Firewall (WAF) systems in Amazon Web Services. The BIG-IP VEs have the Local Traffic Manager (LTM) and Application Security Manager (ASM) modules enabled to provide advanced traffic management and web application security functionality. As traffic increases or decreases, the number of BIG-IP VE WAF instances automatically increases or decreases accordingly. Prerequisites: BIG-IP VE version 13.0 You created your WAF using the F5 Cloud Formation Template or CFT ... (more)

Device Discovery on BIG-IQ 5.1

The first step in using a BIG-IQ to manage BIG-IP devices BIG-IQ enables administrators to centrally manage BIG-IP infrastructure across the IT landscape.  BIG-IQ discovers, tracks, manages, and monitors physical and virtual BIG-IP devices – in the cloud, on premise, or co-located at your preferred datacenter. Let’s look at how to get BIG-IQ 5.1 to gather the information needed to start managing a BIG-IP device. This gathering process is called Device Discovery. To get started, the first thing is to logon to the BIG-IQ Once in, the first thing you do is let the BIG-IQ know about the BIG-IP device that you want to manage. Here, in Device Management>Inventory>BIG-IP Devices, we’ll click Add Device. Here we’ll need the IP address, user name and password of the device you want to manage. If the device you want to manage is part of a BIG-IP Device Service Cluster (DSC... (more)

DevCentral’s Featured Member for May – NTT Security’s Leonardo Souza

Leonardo Souza lives in the United Kingdom, with his partner, 5-year-old daughter, and a (very) recently newborn son. He’s Brazilian and lived in Portugal for quite a while. He then moved to UK about 5 years ago ‘because of the amazing weather,’ he jokes. Leonardo started to work with computers when he was 18 years old (he’s not 18 anymore), so he’s worked with many technologies. Fast forward a bit (he’s not that old) and while working as a network engineer, he was working on a project to migrate applications from Alteon load balancers to F5 BIG-IP LTMs. He completed his LTM Essentials and LTM Advanced training during that time (2011) and with the migration project, he was impressed with BIG-IP. He even applied for a job at F5 in 2012 and joined as a Network Support Engineer. That moved him from Portugal to UK, and has been doing F5 products exclusively ever since. ... (more)

Wearing Emotions on Your Sleeve… Literally By @PSilvas | @ThingsExpo #IoT

I’m sure you’ve heard the saying ‘wearing your heart on your sleeve’ to indicate that someone expresses their emotions freely or exposes their true emotions without caution. This can be good in that you become open and vulnerable when showing your true feelings but can jade areas like composure in situations where you might be frustrated or irritated. I tend to be fairly open with my emotions. There are a few stories about the origin of the saying going back to the Middle Ages. Emperor Claudius II felt unattached men make better warriors so he outlawed marriage. To alleviate some of the grievances, every year during the Roman festival honoring Juno, he’d allow temporary coupling where men drew names to determine who would be their lady friend for the year. The man would wear her name on his sleeve for the festival. Around the same time, when knights performed jousti... (more)
