Computer Network Defense Analyst (CNDA)

Sentar•Augusta, GA

About The Position

Sentar is seeking Computer Network Defense Analysts (CNDA) in Augusta, Georgia. Analysts use information from sources such as intrusion detection systems, firewalls, network traffic logs, and host system logs to identify vulnerabilities, respond to cyber events, and defend against potential events. They help develop mitigations to strengthen network defenses and protect network infrastructure devices and systems from attack. The work may involve traditional wired networks, wireless transport including Wi-Fi and cellular, collaborative platforms such as video teleconferencing, and supporting hardware and software. Analysts work with government, military, and contractor personnel to develop shared understandings of intelligence needs, mission relevance, and areas of expertise. They form and assess hypotheses, select analysis techniques, query and enrich data, and communicate insights. They also document and contextualize findings, including newly developed tradecraft, for teammates, stakeholders, and intelligence consumers. The position offers opportunities to develop expertise in networking protocols and architectures, cloud security, Internet of Things protocols, and advanced network security. The specific labor category is determined by years of experience and educational degrees.
