System characterization is the process of defining the boundaries of an IT system, which includes identifying the resources, information, and functionality that constitute the system. This process is crucial for understanding the scope of the system, the data it processes, and the technology it employs. By characterizing a system, incident handlers can better understand the system's normal operations and behaviors, which is essential for identifying anomalies that may indicate a security incident. System characterization involves documenting the hardware, software, network configuration, data flows, and other critical elements of the IT environment. This foundational knowledge supports effective incident handling by providing a baseline against which suspicious activities can be compared.

References:EC-Council's Certified Incident Handler (ECIH v3) courses and study guides emphasize the importance of system characterization in the incident handling and response process. It serves as a prerequisite for subsequent steps such as threat identification, vulnerability identification, and the implementation of appropriate controls.

Public Key Infrastructure (PKI) is a framework used to manage digital certificates and public-key encryption. It enables secure electronic transfer of information for a range of network activities such as e-commerce, internet banking, and confidential email. PKI is fundamental to the management of encryption keys and digital certificates, ensuring the secure exchange of data over networks and verification of identity.

References:The ECIH v3 program covers the importance of PKI in cloud security controls, emphasizing its role in establishing and maintaining a secure cloud computing environment.

A Denial of Service (DoS) attack aims to make a computer resource, network, or application unavailable to its intended users, thereby preventing legitimate users from using the service. This is achieved by overwhelming the target with a flood of internet traffic or sending information that triggers a crash. In contrast, fraud and theft involve the unauthorized acquisition of data or assets, unauthorized access refers to gaining entry into systems without permission, and malicious code or insider threat attacks relate to software designed to cause harm or unauthorized actions by trusted users within the organization. The specific intent of a DoS attack is to disrupt service, making it a distinct category focused on denial of availability.References:The Incident Handler (ECIH v3) certification materials discuss various types of cybersecurity threats, including DoS attacks, outlining their methods, objectives, and impacts on targeted systems or networks.
