Questions and Answers

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?

  • 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?

  • 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.
