Acceptance testing is a type of testing that involves verifying that an application meets the needs and expectations of the business and the end users. Acceptance testing is usually performed by users or customers who evaluate the application's functionality, usability, performance, reliability, and compatibility. Acceptance testing helps to ensure that the application delivers the required value and quality before it goes into production.

System timeline reconstruction is a forensic analysis technique that involves creating a chronological record of events that occurred on a system based on various sources of evidence such as log files, registry entries, file timestamps, network traffic, etc. System timeline reconstruction can provide information about when and how the machine was compromised and where the malware is located by showing when suspicious activities or changes took place on the system, such as unauthorized access attempts, file creation or modification, process execution, network connections, etc.

Deidentifying a data subject means removing or obscuring any data that can be used to identify, locate, or contact an individual, such as names, addresses, phone numbers, email addresses, social security numbers, etc. Deidentifying a data subject throughout the organization's applications can help comply with the new regulation that requires only retaining the minimum amount of data on a person to perform the organization's necessary activities.

The first action that should be taken to prevent a more serious compromise is to check the hash signatures, comparing them with malware databases to verify if the files are infected. This will help to determine if the changes to hash signatures were caused by malicious software or legitimate updates. If the files are infected, they should be quarantined and removed from the network. Checking the hash signatures will also help to identify the type and source of the malware, which can inform further actions such as blocking malicious domains or IPs, updating antivirus signatures, or notifying users3.

The planning stage of the SDLC process is when the project scope, objectives, requirements, risks, and deliverables are defined and agreed upon by all stakeholders. This stage also involves creating a project plan that outlines the tasks, resources, schedule, budget, and communication channels for the project.
The planning stage is crucial for ensuring that the project is aligned with the business goals and customer needs, and that the project team has a clear vision and direction for the development process. By overlooking this stage, the SOC staff did not receive contact details or escalation procedures to follow in case of a high-severity bug, which could have serious consequences for the security and functionality of the web application.
