• Knowledge of cyber threats and vulnerabilities.
• Knowledge of specific operational impacts of cybersecurity lapses.
• Knowledge of host/network access control mechanisms (e.g., access control list, capabilities list).
• Knowledge of cybersecurity and privacy principles and organizational requirements (relevant to confidentiality, integrity, availability, authentication, non‑repudiation).
• Knowledge of network traffic analysis methods.
• Knowledge of Virtual Private Network (VPN) security.
• Knowledge of transmission records (e.g., Bluetooth, Radio Frequency Identification (RFID), Infrared Networking (IR), Wireless Fidelity (Wi-Fi), paging, cellular, satellite dishes, Voice over Internet Protocol (VoIP)), and jamming techniques that enable transmission of undesirable information, or prevent installed systems from operating correctly.
• Knowledge of network access, identity, and access management (e.g., public key infrastructure, Oauth, OpenID, SAML, SPML).
• Knowledge of system and application security threats and vulnerabilities (e.g., buffer overflow, mobile code, cross‑site scripting, Procedural Language/Structured Query Language [PL/SQL] and injections, race conditions, covert channel, replay, return‑oriented attacks, malicious code).
• Knowledge of different classes of attacks (e.g., passive, active, insider, close‑in, distribution attacks).
• Knowledge of application security risks.

• Must be able to lift up to 10‑20 pounds.
