East/Westbound Interfaces - CORRECT ANSWERSAre meant for communication between groups or federations of controllers. SDN Data Plane - CORRECT ANSWERSTasked with enabling the transfer of data from the sender to the receiver(s).
Attack - CORRECT ANSWERSAn action triggered by deploying an attacking method, when a vulnerability is exploited to actually realize a threat. Risk - CORRECT ANSWERSThe quantifiable likelihood of loss due to a realized threat, and is emphasizes the quantitative of potential damages. Firewall - CORRECT ANSWERSA component or set of components that restricts access between a protected network and the Internet, or between other sets of networks. Intrustion Prevention System (IPS) - CORRECT ANSWERSA network security/threat prevention technology that examines network traffic flows to detect and prevent vulnerability exploits.

Layer 2 Tunneling Protocol (L2TP) - CORRECT ANSWERSA tunneling protocol that does not provide encryption but relies on other protocols like IPsec.
Cyber Kill Chain Reconnaissance - CORRECT ANSWERSOccurs when the attacker gathers information on the target before the actual attack starts. Cyber Kill Chain Weaponization - CORRECT ANSWERSOccurs when attackers do not interact with the intended victim, instead they create their attack. Cyber Kill Chain Delivery - CORRECT ANSWERSOccurs when the attack is transmitted to the indented victim. Cyber Kill Chain Exploitation - CORRECT ANSWERSImplies actual detonation of the attack, such as the exploit running on the system. Cyber Kill Chain Installation - CORRECT ANSWERSHappens when the attacker installs malware on the victim. Cyber Kill Chain Command and Control - CORRECT ANSWERSImplies that once a system is compromised it has to call home to a command and control system. Cyber Kill Chain Actions on Objectives - CORRECT ANSWERSOccurs when the attackers establish access to the organization, so they can then execute actions to achieve their objectives/goals.
