For a project for one of our client based in Amsterdam, Trasys International is looking for a SOC Analyst.

The consultant will act as the first line of response regarding the potential occurrence of a cyber attack or security incident. Supported by several automated tools such as intrusion detection systems, log correlation engines and SIEM, ticketing system, alerts and warning from internal and external sources, this service involves receiving, triaging and responding to alerts, requests and reports, and analysing events and potential incidents and to provide the primary support for incident responders. Triage involves assessing whether a security incident or the level of exposure of a vulnerability is a true or false positive, tagging the vulnerability or incident with an initial severity classification and to activate the corresponding incident response playbook entry. Another objective of this service is to follow pre-defined procedures to perform technical tasks related to identity and access management.

  • Analysing risks and security policy requirements;
  • Translating them into technical events targeting the system components;
  • Identifying the required logs/files/artefacts to collect from the monitored system and, if necessary, possible complementary devices to deploy;
  • Elaborating the relevant detection and correlation rules;
  • Implementing these rules in the SIEM infrastructure;
  • Configuring and tuning cyber-defense solutions;
  • Integrate cyber-defence solutions for efficient detection;
  • Produce qualified reports (including recommendations) or alerts to SOC customers and follow-up on actions;

  • During security incidents, implement detection means to monitor attacker activities in realtime;
