An Inappropriate Usage incident refers to instances where computing resources are misused or abused, often violating organizational policies or laws. While access-control attacks, reconnaissance attacks, and denial-of-service (DoS) attacks represent different types of external threats or methods of attack, an Insider Threat is an example of inappropriate usage. Insider threats come from individuals within the organization, such as employees or contractors, who misuse their access to harm the organization's interests. This can include stealing confidential information, intentionally disrupting systems, or other malicious activities that leverage their legitimate access to the organization's resources.References:EC-Council's Incident Handler (ECIH v3) materials often discuss various typesof security incidents, including inappropriate usage, and emphasize the importance of recognizing and preparing for insider threats as a critical component of an organization's incident response strategy.

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.

In the context of incident handling, the "point of contact" list is essential for ensuring that Sheila, the incident handler working at night, can quickly notify the responsible personnel within the organization about the cyberattack. This list typically includes the contact information of key stakeholders and decision-makers who need to be informed about security incidents, allowing for timely communication, decision-making, and response coordination.

References:Incident Handler (ECIH v3) courses and study guides stress the importance of having a well-maintained point of contact list as part of an organization's incident response plan to facilitate efficient and effective communication during and after cybersecurity incidents.

The regular expression/exec(\s|\+)+(s|x)p\w+/ixis designed to match patterns that resemble SQL injection attempts, specifically targeting MS SQL Server. This expression looks for the use of theexeccommand followed by one or more spaces or plus signs, and then patterns that start withsporxp, which are prefixes commonly used in SQL Server stored procedures and extended stored procedures. These are often targeted in SQL injection attacks to execute malicious SQL statements. The regular expression provided is a tool used by incident responders like Tibson to identify and analyze potential SQL injection attempts by looking for suspicious patterns in SQL queries.
