What capability do ICE (Intrusion Countermeasure Equipment) agents have in the event of an intrusion detection alert?
What capability do ICE (Intrusion Countermeasure Equipment) agents have in the event of an intrusion detection alert?
- Automatically lock down a network or increase access security to critical resources (correct)
- Shut down all network operations to contain the intrusion
- Create fake attack logs to confuse the intruder
- Initiate a counter-attack against the intruder
What is one purpose of redirecting or misdirecting an attacker to secured segmented areas?
What is one purpose of redirecting or misdirecting an attacker to secured segmented areas?
- Prompting the attacker to launch more sophisticated attacks
- Preventing access to secured resources and gaining time to trace or track the intruder (correct)
- Facilitating the spread of the attack to other network segments
- Allowing the attacker to gain access to secured resources
What is the purpose of forensic analysis of infected systems after identifying an attack?
What is the purpose of forensic analysis of infected systems after identifying an attack?
- To learn new attack techniques from the infected systems
- To provide additional access to the attacker for further analysis
- To detect information about the identity of the attacker for potential legal action (correct)
- To cover up evidence of the attack and protect the network's reputation

Study Notes
ICE Agents Capabilities
- ICE (Intrusion Countermeasure Equipment) agents respond to intrusion detection alerts by initiating countermeasures to mitigate the impact of an attack.
- Their actions may include isolating affected systems, deploying security protocols, or initiating protocol reviews to protect sensitive information.
Redirecting Attackers
- One purpose of redirecting or misdirecting an attacker to secured segmented areas is to protect critical assets and resources from being accessed or compromised.
- This tactic helps in confusing attackers while allowing security personnel to monitor and analyze their activities.
Forensic Analysis Purpose
- Forensic analysis of infected systems is conducted to gather crucial details about the attack, including the attack vectors and methods used by the intruders.
- This analysis aids in understanding vulnerabilities and designing better defenses against future attacks.
Communicating Intrusion Analysis
- The analysis of successful intrusions should be documented and communicated effectively to inform system hardening efforts and enhance overall security measures.
- Insights gained from the analysis are vital in adjusting existing security protocols and implementing new defenses.
Challenges with IDS
- Intrusion Detection Systems (IDSs) often produce false positives, resulting in unnecessary alerts and potentially desensitizing teams to legitimate threats.
- The reliance on IDS alone may lead to gaps in security as some sophisticated attacks can evade detection, emphasizing the need for comprehensive security strategies.
