CREST Certified Network Intrusion Analyst


The Certified Network Intrusion Analyst (CCNIA) examination tests candidates’ knowledge of analysing network traffic and log files for evidence of potential compromise and analysing the potential underlying causes and infection vectors.

The examination is a rigorous assessment of the candidate’s ability to assess a given network for indications of malicious activity including remote control and data ex-filtration.

The exam includes:

  • Data Sources
  • Statistical Analysis
  • Beaconing Systems
  • Encrypted Communications
  • Network Traffic Analysis
  • Networking Protocols
  • Covert Channel Identification
  • Log Analysis

 Examination format
The format is the same as for all other CREST certifications. The candidate will be expected to possess not only the technical ability to find security weaknesses and vulnerabilities, but also the skills to ensure findings are presented in a clear, concise and understandable manner. The examination consists of three tasks:

  • A multiple choice technical examination
  • A long form essay style written paper, testing both technical ability and presentation ability
  • A hands-on practical examination

To pass the exam, the candidate must pass all three sections.
