ECCouncil 212-89 - EC Council Certified Incident Handler (ECIH v3)

Employee monitoring tools are primarily used by employers to detect and prevent malicious insider threats. These tools can track activities such as data access, data exfiltration attempts, unauthorized actions, and other behaviors that could indicate malicious intent or pose a risk to the organization ' s security. While such tools may also incidentally uncover issues like lost registry keys, conspiracies, or stolen credentials, their main purpose is to safeguard against insiders who might misuse their access to harm the organization, steal data, sabotage systems, or engage in espionage.

Access logs showing that the compromised account reached critical files provide the strongest direct evidence that unauthorized access progressed beyond attempted authentication. ECIH v3 incident validation emphasizes using reliable indicators that demonstrate successful access to protected resources and help establish the scope of compromise. Failed authentication attempts are suspicious, but they do not by themselves confirm successful intrusion. Once an administrative account has been compromised and logs show access to restricted files, responders have direct evidence that security controls were bypassed and protected resources were accessed. High CPU utilization can have many legitimate causes, while new processes may be created by normal software or system activity. Suspicious DNS behavior can indicate malware or command-and-control traffic but does not independently establish unauthorized file access. Therefore, access logs involving critical resources are the strongest indicator.

When a browser does not expire a session after the user fails to logout properly, it is indicative of a vulnerability related to broken authentication. Broken authentication is a security issue where attackers can exploit flaws in the authentication mechanism to impersonate other users or take over their sessions. Failure to properly manage session lifetimes, such as not expiring sessions on logout, can allow an attacker to reuse old sessions or session IDs, potentially gaining unauthorized access to user accounts. This vulnerability is classified under A2: Broken Authentication in the OWASP Top 10, which lists the most critical web application security risks. The OWASP Top 10 serves as a guideline for developers and web application providers to understand and mitigate common security risks.

A TCP Xmas scan is a type of network scanning technique used by attackers to identify open ports on a target machine. The name " Xmas " comes from the set of flags that are turned on within the packet, making it ' lit up like a Christmas tree ' . Specifically, the FIN, PSH, and URG flags are set, which corresponds to the hexadecimal value 0X029 in the TCP header ' s flags field. Wireshark, a popular network protocol analyzer, allows users to create custom filters to detect specific types of network traffic, including malicious scanning attempts. By using the filtertcp.flags==0X029, Rose can detect packets that have these specific flags set, indicating a potential TCP Xmas scan attempt.

The vulnerability exploited by Clark through tampering with form and parameter values to gain unauthorized access to information assets is indicative of Broken Access Control. Broken Access Control vulnerabilities occur when a web application does not properly enforce restrictions on what authenticated users are allowed to do. Attackers can exploit these vulnerabilities to access unauthorized functionality or data, such as accessing other users ' accounts, viewing sensitive files, and modifying other users’ data.

MxToolbox is an online tool that provides various network diagnostics and email security checks, including looking up DNS and MX records, SPF records, and more. It can be used by incident handlers to prevent the organization against evolving email threats by analyzing domain health, checking blacklists, verifying email delivery issues, and more. While Email Header Analyzer is useful for analyzing specific emails for traces of phishing or spoofing, G Suite Toolbox might be specific to Google ' s services, and Gpg4win is more focused on email encryption. MxToolbox provides a broader set of functionalities for monitoring and troubleshooting email delivery issues and security threats, making it a versatile tool for incident handlers.

A rogue-access point attack occurs when attackers or insiders install an unsecured access point within a trusted network, typically behind a firewall, to create a backdoor. This allows them to bypass network security measures and perform various malicious activities undetected. The use of any software or hardware access point to gain unauthorized access and conduct an attack characterizes a rogue-access point attack. This contrasts with password-based attacks, malware attacks, and email infections, which involve different methodologies and objectives, such as stealing credentials, distributing malicious software, or propagating through email systems, respectively.

This question is based on the shared responsibility model, a fundamental concept in ECIH cloud incident handling. While customers manage applications, configurations, and data, the cloud service provider (CSP) controls the underlying infrastructure, including orchestration engines, schedulers, and runtime environments.

System-level telemetry such as hypervisor activity and orchestration logs cannot be accessed by customers. Only the CSP can provide this visibility. Therefore, Option C is correct.

The other options manage higher-level responsibilities but lack authority over infrastructure-layer components.

Omnipeek is a network analyzer tool that allows for the capture and analysis of data packets transmitted across a network. It is designed to provide deep insights into network traffic, enabling users to examine various aspects of the data packets, including network protocols, ports, devices, and potential issues in network transmission. This tool would be ideal for Chandler, who is targeting the Technote organization with the intent of intercepting and analyzing network traffic to obtain sensitive organizational information. Omnipeek ' s capabilities in packet analysis make it suitable for such activities, offering detailed visibility into the network ' s operation and data flows.

Michael ' s activities, which involve analyzing file systems, slack spaces, and metadata of storage units to find hidden malware and evidence of malice, indicate that he is handling a storage-related cloud security incident. This type of incident pertains to unauthorized access, alteration, or exfiltration of data stored in cloud environments. By focusing on the storage aspects such as file systems and metadata, Michael is looking for signs of compromise that specifically affect the storage of data, which is indicative of a storage-related security incident in the cloud.
