Table 4

Difference between various cyber defense techniques.

Technique	Security features	Threats addressed	Threats unaddressed
Network-based MTD	Operational confidentiality, state obfuscation, attack surface extension	DoS, MitM, spoofing, insider threat, targeted attack	Replay and random attacks
Firewall/IDS/IPS	Monitoring, exfiltration, signature analysis, anomalous behavior detection	Malicious traffic filtering	Masquerade, authentication attack
DNP3sec	Authentication and integrity check	Replay, spoofing, modification, nonrepudiation	DoS, traffic attack, zero day exploits
Scalence/VPNsec/GRE tunnelling	Confidentiality, transparent application-level security	IPSec-application layer attack	APT, rootkit, trapdoor, stealth DoS, phishing attack, network layer attack, SSLSec-application layer attack
