? Explanation:

In-line hardware keyloggers are physical devices placed between a keyboard and a computer.

They are a concern because they are not detectable by software-based monitoring tools, posing a significant risk to the confidentiality of sensitive information.

? Why Other Options Are Incorrect:

A. Don’t require physical access: Physical access is required to install the hardware.

B. Don’t comply with regulations: While true, this is a secondary concern compared to their undetectability.

D. Are relatively inexpensive: Cost is a factor but not the primary security concern.

? EC-Council CISO Reference:

The curriculum addresses the risks posed by hardware-based attacks and the need for physical security controls to mitigate such threats.

? Explanation:

Incident response encompasses the processes and actions taken to assess, contain, and mitigate security breaches.

It includes detection, investigation, containment, and recovery activities.

? Why Other Options Are Incorrect:

A. IT support team: May assist but lacks the specialized role of incident response teams.

B. Forensic analysis: A part of the incident response process but does not encompass the entire containment effort.

D. Physical security team: Relevant for physical breaches, not digital security incidents.

? EC-Council CISO Reference:

Incident response is a critical component of the CISO role, focusing on minimizing damage and ensuring swift recovery from breaches.

? Understanding SQL Injection Attacks:

SQL injection exploits vulnerabilities in an application’s interaction with a database by injecting malicious SQL code to manipulate queries.

? About the Text ' or 1=1 --:

The input ' or 1=1 -- always evaluates to true (1=1) and the -- comments out the rest of the SQL statement.

This allows attackers to bypass authentication or extract unauthorized data.

? Why Not Other Options:

B. /../../../../: Represents a directory traversal attack, not SQL injection.

C. "DROP TABLE USERNAME": A destructive SQL command but not indicative of basic injection techniques.

D. NOPS: Refers to no-operation instructions used in buffer overflow attacks, not SQL injection.

? EC-Council Guidance:

Recognizing and mitigating SQL injection is critical to securing database-driven applications, as emphasized in secure coding practices.
