Relevant professional certifications in networking, cyber security or information security would be advantageous. You should be analytical, methodical and confident investigating complex technical issues, with the ability to communicate clearly with both technical and non-technical stakeholders. A proactive approach, strong attention to detail and a commitment to maintaining current knowledge of emerging threats and defensive technologies are essential.
