What is a Cyber Defense Incident Responder?

The Cyber Defense Incident Responder investigates, analyzes, and responds to cyber incidents within the network environment or enclave.

Cyber Defense Incident Responder must know:

  • computer networking concepts and protocols, and network security methodologies.
  • risk management processes (e.g., methods for assessing and mitigating risk).
  • laws, regulations, policies, and ethics as they relate to cybersecurity and privacy.
  • cybersecurity and privacy principles.
  • cyber threats and vulnerabilities.
  • specific operational impacts of cybersecurity lapses.
  • data backup and recovery.
  • business continuity and disaster recovery continuity of operations plans.
  • host/network access control mechanisms (e.g., access control list, capabilities lists).
  • network services and protocols interactions that provide network communications.
  • incident categories, incident responses, and timelines for responses.
  • incident response and handling methodologies.
  • intrusion detection methodologies and techniques for detecting host and network-based intrusions.
  • network traffic analysis methods.
  • packet-level analysis.
  • 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).
  • what constitutes a network attack and a network attack’s relationship to both threats and vulnerabilities.
  • cyber defense and information security policies, procedures, and regulations.

  • different classes of attacks (e.g., passive, active, insider, close-in, distribution attacks).
  • cyber attackers (e.g., script kiddies, insider threat, non-nation state sponsored, and nation sponsored).
  • system administration, network, and operating system hardening techniques.
  • cyber attack stages (e.g., reconnaissance, scanning, enumeration, gaining access, escalation of privileges, maintaining access, network exploitation, covering tracks).
  • network security architecture concepts including topology, protocols, components, and principles (e.g., application of defense-in-depth).
  • OSI model and underlying network protocols (e.g., TCP/IP).
  • cloud service models and how those models can limit incident response.
  • malware analysis concepts and methodologies.
  • an organization’s information classification program and procedures for information compromise.
  • network protocols such as TCP/IP, Dynamic Host Configuration, Domain Name System (DNS), and directory services.
  • the common networking and routing protocols (e.g. TCP/IP), services (e.g., web, mail, DNS), and how they interact to provide network communications.
  • Application Security Risks (e.g. Open Web Application Security Project Top 10 list)

Key Skills of the Cyber Defense Incident Responder include:

  • identifying, capturing, containing, and reporting malware.
  • preserving evidence integrity according to standard operating procedures or national standards.
  • securing network communications.
  • recognizing and categorizing types of vulnerabilities and associated attacks.
  • protecting a network against malware. (e.g., NIPS, anti-malware, restrict/prevent external devices, spam filters).
  • performing damage assessments.
  • using security event correlation tools.
  • design incident response for cloud service models.

Cyber Defense Incident Responder must be able to:

  • design incident response for cloud service models.
  • apply techniques for detecting host and network-based intrusions using intrusion detection technologies.
