This is what you do for our customer

You will work on the technologies of tomorrow, today. Even though communication services are a given part of our lives, they continuously evolve to become more and more sophisticated, containing more and more personal and financial data, at an astonishing rate. As a result, it is of utmost importance to protect our customers’ data according the latest security standards and policies, and beyond.

This is how you do it

As security specialist, you will work in the cyber security team in the security operations area. This includes activities like security incident management, digital forensics, CSIRT (Cyber Security Incident Response Team) and vulnerability and hardening/compliance management.

You will follow up on cyber security incidents that are reported via several different channels. Further, you will also be part of or lead a CSIRT team when needed. Threat intelligence, vulnerability-, hardening management and digital forensics are also a part of your activities.

In an ever-changing threat landscape and dynamic environment continuous improvement is key. You will be a driver of these improvements on the operational model, processes, tools and knowledge.

As a Security Specialist your main responsibilities will involve:   

  • Review and respond to security incidents, events and alerts as reported via for example our Security Operation Center (SOC).
  • Act as an Incident handler or coordinator and be part or lead the CSIRT team.
  • Play an active role in digital forensics on cyber security incidents.
  • Follow up on threat intelligence notifications.
  • Drive continuous improvements and contribute to efficiency and effectiveness of the operation.
  • Advise senior management on security topics.
