An IDS developer, or Intrusion Detection System developer, designs, implements, and maintains software systems that monitor network or system activities for malicious behavior or policy violations. Their tasks include writing algorithms to detect suspicious patterns, testing and updating IDS software, configuring security alert settings, and analyzing security breaches. They also work closely with cybersecurity teams to reinforce security measures and provide solutions to detected threats. Their goal is to ensure the integrity, confidentiality, and availability of data by preventing unauthorized access or damage to computer networks and systems.
