212-89 Exam Dumps : EC Council Certified Incident Handler (ECIH v3)

The EC-Council Incident Handler (ECIH) curriculum explains that insider data exfiltration frequently occurs through legitimate channels such as HTTPS to bypass traditional firewall rules. When encrypted traffic is not inspected, sensitive data can be transmitted without detection.

Data Loss Prevention (DLP) tools monitor, detect, and block unauthorized transmission of sensitive information across endpoints, networks, and cloud services. DLP solutions can inspect encrypted traffic (when integrated with SSL/TLS inspection mechanisms) and enforce policies that prevent confidential data from leaving the organization.

The absence of deep packet inspection allowed encrypted HTTPS traffic to evade detection. Implementing DLP would provide content-aware monitoring and policy-based enforcement, reducing insider exfiltration risk.

Option A (biometric authentication) controls access, not outbound data flows. Option C (secure coding) relates to software development security. Option D (USB blocking) addresses removable media exfiltration, not encrypted network traffic.

Therefore, implementing Data Loss Prevention (DLP) tools is the appropriate eradication control.

The incident involves an active cloud-based malware compromise rather than merely an operational scheduling issue. ECIH v3 cloud incident handling emphasizes using cloud-aware security capabilities to identify compromised resources, determine attack scope, detect malicious workloads or processes, and support containment and eradication. Deploying the available cloud security tool directly addresses the active threat and can help identify how the malware is spreading through the cloud environment. Monitoring flight schedules provides operational visibility but does not stop malicious activity. Halting all flights would be a severe business and safety decision that should not be taken without evidence that such disruption is necessary. Passenger notification may eventually be required depending on operational impact but does not remediate the security incident. Therefore, targeted technical investigation and containment using the cloud-specific security tool is the appropriate primary action.

Email-bombing refers to the attack where the attacker sends a massive volume of emails to a specific email address or mail server in order to overflow the mailbox or overwhelm the server, potentially causing it to fail or deny service to legitimate users. This attack can disrupt communications and, in some cases, lead to the targeted email account being disabled. Masquerading involves pretending to be another legitimate user, spoofing is the creation of emails (or other communications) with a forged sender address, and a smurf attack is a specific type of Distributed Denial of Service (DDoS) attack that exploits Internet Protocol (IP) and Internet Control Message Protocol (ICMP) to flood a target with traffic. Email-bombing specifically targets email services with the goal of causing disruption by overflowing inboxes.
