Cyberworkplace welcomes a new intern

We are super happy to welcome in our team Dylan Baalbergen, as our new intern! Dylan is a first-year Human Resource Management student at Leiden University College. He wants to expand his knowledge in human resources, by learning as much as possible here at Cyberworkplace. During his internship, he will be helping us with drawing up a recruiting model for students, volunteers, and interns, but also a program to better bind them. Dylan is the first intern at Cyberworkplace who is going to work on the abovementioned assignments, thus we are very excited to have him into our team and support/guide him along the way.

Immediately, interest strikes, when during his very first Cyberworkplace workshop he feels nostalgic hearing about programming, as he also used to study IT. He is at the right place to gain some valuable skills, and to put those to good use.

Online course on Splunk

From April 24 to May 15, Cyberworkplace and UMBRiO, an award-winning Splunk Elite Partner in The Netherlands, organize the “Introduction to Splunk” course. Splunk is software that indexes, manages, and enables you to search for data from any application, server, or network device in real-time. Organizations across the globe rely on Splunk to modernize and strengthen their cyber defenses. For Cyberworkplace, Splunk is a great addition to its ambitious ethical hacking curriculum.

During the Cyberworkplace course, students learn how to search and navigate in Splunk, how to use Splunk’s commands, create reports, dashboards, and alerts and use the interactive Pivot tool. The second part of the course focuses on Splunk Enterprise Security where students learn how to monitor, detect, investigate, and respond to threats with analytics-driven SIEM solutions.

The innovative Cyberworkplace/Splunk course is lead by security architect Mark Brinkman, who is responsible for New implementations and usage of Splunk platforms at UMBRiO. In addition, interesting guest speakers from the UMBRiO network will share their knowledge from practice.

Because COVID-19, the course will be offered remotely. Read more about it here.

In February this year, UMBRiO and Cyberworkplace joined forces in a unique collaboration. UMBRiO is happy to support Cyberworkplace’s mission and helps by offering lessons and internships. Read more about the partnership here.

Cyberworkplace enabled me to transition from a student to a young professional

Who is Tsvetelina?

My name is Tsvetelina or just Lina. I am from Bulgaria, 23 years old. In January this year, I graduated MSc in Crisis in Security Management at Leiden University and I am still completing MSc in Cybersecurity in Bulgaria.
My interest falls in the field of security and technology, more specifically in information security and lately privacy. Apart from that, I also like horse riding and yoga.

Student at Cyberworkplace

When did you join Cyberworkplace?  What was your motivation?

I joined Cyberworkplace back in February 2019. My main motivation was to learn some more technical skills and to find a group of like-minded people that are just as passionate about computers and security. Also, I wanted to make the transition between a non-technical career path to one involved more into ICT and I thought Cyberworkplace was a good place to start.

What did you like about Cyberworkplace?

There are so many great things about Cyberworkpace. I really liked the fact that we had space and the environment to develop our tech skills in a more informal setting, but also the responsibility to do so in our own way. In that sense, it’s very different from school or university. Cyberworkplace has always provided the resources and logistics for students to learn, but also it depends on people’s own motivation and effort to succeed.
Also, you get introduced to many different organizations and companies from various fields of work within cybersecurity, so you can really find what you like specifically.

What have you learned at Cyberworkplace?

Many different things. From coding, through digital forensics, lockpicking and building an escape room! Another very important skill I managed to master during my time there was to provide feedback and peer-to-peer learning, which is also very important when a young adult is entering the workforce.
Further, I had the possibility to follow courses and presentations in Dutch. For an international like me, it’s very important to learn the technical terminology in the country that you’re working in, so CWP also provided me with the opportunity to do so.

What is your most favorite moment at Cyberworkplace?

The CyberHeroes project we had last year. We had the chance to meet not only different organizations and people from all around the world, but also to play not one, but two CTFs.

What are you currently up to?

I am currently working as a Tester at Cybersprint to which I got introduced via Cyberworkplace. Also, I am doing an internship in the cybersecurity section of an international organization.
Also, I am following a course for certification in the IT Security Administration that was also provided by one of Cyberworkplace’s partners, SECO Institute.

Describe Cyberworkplace with three words?

Learn. Fun. Collaborate.

Would you recommend Cyberworkplace to your friends? What would you tell them?

I definitely recommend it to all my friends and connections. Very often I hear people say “Oh, I find cybersecurity very interesting, but I am not very technical. ” or “I wanna do it, but I don’t know where to start.”. Cyberworkplace is a great start. You have people with different interests and skill levels, which are willing to spend time with you and help you find what you like and what potentially you are good at.
Furthermore, from a networking perspective, Cyberworkplace, its ambassadors, board and partnering organizations are always willing to support your future goals.

Is there anything else that you would like to add?

I would like to thank everyone involved in Cyberworkplace and its projects: from organizers, supporters to the students. Everybody there has enabled me to transition from a student to a young professional and from a non-technical to a (more) technical person.
I also hope that I will be able to contribute to CWP and its mission in the future, so more young people like myself can find how cool cyber is.

De Cyberworkplace is open in cyberspace! “Eigenlijk zijn we als ethische hackers nu nog meer in ons element”

De Rotterdamse Cyberworkplace sluit als gevolg van het Coronavirus tijdelijk de fysieke deuren.  Online gaan de lessen in ethisch hacken echter op volle kracht door. En dat is hard nodig, zegt Cyberworkplace voorzitter Anouk Vos. “Cybercriminelen maken misbruik van de Corona-onrust. In de afgelopen dagen verschenen meldingen van hacks op bedrijven als en malafide apps en nep-e-mails over het virus.”

De Cyberworkplace biedt jongeren daarom in de komende weken online presentaties en trainingen in  het voorkomen van cyberaanvallen aan. Jongeren krijgen les in ethisch hacken en leren hoe zij  organisaties kunnen helpen zich tegen cybercriminelen te beschermen. Verschillende IT-bedrijven en  vrijwilligers helpen mee. Zo geeft het bedrijf Securelink uit Sliedrecht online workshops en worden er hackwedstrijden georganiseerd. ICT-bedrijf Cisco heeft de jongeren verder kosteloos toegang tot hun trainingsomgeving gegeven.

“Jongeren zitten lange uren thuis. Dat is eerst leuk, maar al snel kan de verveling de kop opsteken” zegt Vos. “Als je handig bent met computers kun je een beetje online rotzooi gaan trappen, maar je kunt ook met ons contact opnemen. Juist nu we meer dan ooit online aan het werk zijn, hebben we
tech-talenten nodig om ons digitale leven veilig te houden”Cyberworkplace

De Cyberworkplace is een non-profit, collegegeld-vrij initiatief dat het tekort in cybersecurity-expertise op de arbeidsmarkt verkleint door Rotterdamse jongeren 21ste-eeuwse ICT-vaardigheden bij te brengen en relevante werkervaring op te laten doen.
