In Wireshark, to identify ICMP ping sweep attempts, the filtericmp.type == 8 or icmp.type ==0is used. This filter captures ICMP echo requests and echo replies, which are indicative of ping commands. Type 8 represents an echo request used when a source sends a ping, and type 0 represents an echo reply, which is the response from the target. By filtering for these ICMP types, Miko can detect a surge in ping requests across the network, which could indicate a ping sweep attempt-an exploratory activity often used by attackers to discover active hosts on a network by sending ping requests to multiple addresses.References:Incident Handler (ECIH v3) courses and study guides often incorporate training on using network analysis tools like Wireshark, including how to use filters to detect specific types of network activities and potential threats.

Behavioral analysis is a technique used to detect insider threats by analyzing the behavior of employees, both individually and in group settings, to identify any actions that deviate from the norm. This method relies on monitoring and analyzing data related to user activities, access patterns, and other behaviors that could indicate malicious intent or a potential security risk from within the organization. Behavioral analysis can detect unusual access to sensitive data, abnormal data transfer activities, and other indicators of insider threats. This approach is proactive and can help in identifying potential insider threats before they result in significant harm to the organization.References:The Incident Handler (ECIH v3) certification materials cover various insider threat detection techniques, including the importance of behavioral analysis as a key method for identifying potential security risks posed by insiders.

Email Dossier is a tool designed to perform detailed investigations on email messages to verify their authenticity and trace their origin. It can analyze email headers and provide information about the route an email has taken, the servers it passed through, and potentially malicious links or origins. For an incident handler like Stenley, tasked with verifying the validity of emails and containing malicious email threats, Email Dossier serves as a practical tool for analyzing and validating emails received by employees. By using this tool, Stenley can identify fraudulent or suspicious emails, thereby helping to protect the organization from phishing attacks, malware distribution, and other email-based threats.
References:In the context of managing and mitigating the risks associated with email communications, ECIH v3 study materials outline various tools and techniques for email analysis and validation. These resources recommend the use of tools like Email Dossier for incident handlers to effectively scrutinize incoming emails for security threats.
