Knowledge of OSI model and underlying network protocols (e.g., TCP/IP).

Items denoted by a * are CORE KSATs for every Work Role, while other CORE KSATs vary by Work Role.


Core KSAT for the following Work Roles

All-Source Analyst (Core) ID: 111 (NIST ID: AN-ASA-001) Workforce Element: Intelligence (Cyberspace)

Analyzes data/information from one or multiple sources to conduct preparation of the environment, respond to requests for information, and submit intelligence collection and production requirements in support of planning and operations.

Cyber Defense Incident Responder (Core) ID: 531 (NIST ID: PR-IR-001) Workforce Element: Cybersecurity

Investigates, analyzes, and responds to cyber incidents within the network environment or enclave.

Additional KSAT for the following Work Roles

Cyber Defense Analyst (Additional) ID: 511 (NIST ID: PR-DA-001) Workforce Element: Cybersecurity

Uses data collected from a variety of cyber defense tools (e.g., IDS alerts, firewalls, network traffic logs.) to analyze events that occur within their environments for the purposes of mitigating threats.

Host Analyst (Additional) ID: 463 (NIST ID: N/A) Workforce Element: Cyberspace Effects

A Host Analyst (HA) will have knowledge of various system configurations encountered. This work role also performs analysis using built-in tools and capabilities. A Host Analyst will have knowledge of system services and the security and configuration of them, as well as knowledge of file systems, permissions, and operation system configurations. The Host Analyst conducts analysis using built-in tools and capabilities.

Network Analyst (Additional) ID: 443 (NIST ID: N/A) Workforce Element: Cyberspace Effects

The Network Analyst will understand network traffic signatures and discover anomalies through network traffic and packet capture (PCAP) analysis. The Network Analyst will identify, assess, and mitigate intrusions into networks that are vital to cyberspace operations security. Network Analysts also use GUI or command-line based tools and assist in developing network mapping and signatures. Network Analysts will develop advanced network detection rules and alerts, queries and dashboards to gain a holistic view of the network.

Network Technician (Additional) ID: 442 (NIST ID: N/A) Workforce Element: Cyberspace Effects

The Network Technician provides enterprise and tactical infrastructure knowledge, experience, and integration to the Cyber Protection Team (CPT). The Network Technician supports CPT elements by understanding of network technologies, defining mission scope, and identifying terrain.
