A web application firewall (WAF) is a security solution that monitors and filters the traffic between a web application and the internet. It can prevent code injection attacks by blocking malicious requests that contain code snippets or commands that could compromise the web application. A WAF can also enforce input validation rules and sanitize user inputs to prevent code injection.

Dynamic code analysis is a technique that tests and analyzes an application during runtime to identify potential vulnerabilities, errors, or performance issues. Dynamic code analysis can detect problems that may not be visible in the source code or during static analysis, such as memory leaks, buffer overflows, or input validation errors. Dynamic code analysis can also simulate real-world scenarios and user inputs to evaluate the behavior and functionality of the application.

WPA2 (Wi-Fi Protected Access 2) is a network security protocol that should be implemented to ensure the strongest encryption for a wireless network. WPA2 is an upgrade from the original WPA protocol, which was designed as a replacement for the older and less secure WEP protocol. WPA2 implements the mandatory elements of IEEE 802.11i standard, including CCMP, an AES-based encryption mode. WPA2 provides stronger security and data protection than WPS (Wi-Fi Protected Setup), WAP (Wireless Application Protocol), or HTTPS (Hypertext Transfer Protocol Secure)

A smart card is a physical device that contains an embedded integrated circuit chip that can store and process data. A smart card can be used as a second authentication factor, in addition to a password, to verify the identity of a user who wants to log in to company-owned devices. A smart card requires a smart card reader to access the data on the chip, which adds an extra layer of security. A smart card meets the requirements of the company because it does not involve a smartphone or any other device that is not allowed at the desks

A SIEM (Security Information and Event Management) is a system that collects, analyzes, and correlates data from multiple sources, such as AV (antivirus), EDR (endpoint detection and response), DLP (data loss prevention), SWG (secure web gateway), WAF (web application firewall), MDM (mobile device management), HIPS (host intrusion prevention system), and CASB (cloud access security broker). A SIEM can help improve the situation by providing a centralized view of the security posture, alerts, and incidents across the organization.

Thin clients are devices that rely on a server or a cloud service to perform most of the processing and storage tasks, while only providing a minimal interface for the user. Thin clients are low-cost solutions that can enable users on the shop floor to log in to the VDI (virtual desktop infrastructure) environment directly, without requiring a full-fledged computer or laptop.

A replay attack is a type of network attack where an attacker captures and retransmits a valid data transmission, such as a login request, to gain unauthorized access or impersonate a legitimate user.

In this case, the attacker may have captured the credentials of the app admin test account and used them to log in to the application. The application log shows multiple failed login attempts from different IP addresses, which indicates a replay attack.

Security awareness training is an administrative control that educates users on the best practices and policies for protecting the organization's data and systems from various threats, such as malware, phishing, social engineering, etc. Security awareness training can reduce the occurrence of malware execution by increasing the users' ability to recognize and avoid malicious links, attachments, downloads, or websites.
