Describe these evasion methods Implementing Cisco Cybersecurity Operations (210-255) Encryption and Tunneling: Attackers use encryption and tunneling to obfuscate their attacks. VPN technologies like IPSec can be used to keep IPS/IDS from seeing the command and control traffic or even the attack traffic. Resource Exhaustion: A denial of service attack against security appliances like IPS […]
Describe these endpoint-based attacks Implementing Cisco Cybersecurity Operations (210-255) Buffer Overflows Buffer overflow attacks occur when an attacker sends more data that the application expects. If the input is unchecked, an attacker can force a program to execute code in memory sections it shouldn’t have access to. Command and Control (C2) Command and control traffic […]
Describe these attacks: Social Engineering, Phishing, Evasion Methods Implementing Cisco Cybersecurity Operations (210-255) Social Engineering Social engineering is a style of attack where the attacker goes after the human element.
