Alternate encoding such as hexadecimal representations is most often observed in cross site scripting (XSS) attacks. XSS is a type of web application attack that involves injecting malicious code or scripts into a web page or a web application, usually through user input fields or parameters. The malicious code or script is then executed by the victim's browser, and can perform various actions, such as stealing cookies, session tokens, or credentials, redirecting to malicious sites, or displaying fake content. Alternate encoding is a technique that is used by attackers to bypass input validation or filtering mechanisms, and to conceal or obfuscate the malicious code or script. Alternate encoding can use hexadecimal, decimal, octal, binary, or Unicode representations of the characters or symbols in the code or script .

The primary action that should be taken to improve SIEM performance in a situation where several unsuccessful login attempts are reported by a security audit but not by the SIEM system is to confirm alarm thresholds. A SIEM system is a tool that collects, correlates, analyzes, and reports on security events and incidents from various sources, such as logs, sensors, or agents. A SIEM system can also generate alerts or alarms based on predefined rules or thresholds that indicate a potential security issue or violation. However, if the SIEM system is not configured properly, it may miss some important events or incidents, or generate too many false positives or negatives. Therefore, it is important to confirm that the alarm thresholds are set appropriately, based on the risk appetite, the baseline behavior, and the security objectives of the organization.
The alarm thresholds should be neither too high nor too low, to avoid missing or ignoring real threats, or overwhelming or desensitizing the security analysts. References: CISSP All-in-One Exam Guide, Chapter 7:

The main consideration for building a security operations center (SOC), regardless of the model, is the scope and service catalog. The scope and service catalog define the objectives, functions, and deliverables of the SOC, such as monitoring, detection, analysis, response, and reporting of security incidents and events. The scope and service catalog also specify the roles and responsibilities, processes and procedures, standards and metrics, and tools and technologies that the SOC will use to perform its tasks. The scope and service catalog should align with the organization's security policies and strategies, and meet the expectations and requirements of the stakeholders and customers. The scope and service catalog should also be flexible and scalable, to adapt to the changing security landscape and threats. The other considerations, such as skill set and training, headcount and capacity, and tools and technologies, are important, but they depend on the scope and service catalog of the SOC12.
