The first step in forensic analysis is to collect the most volatile data, which is the information that would be lost when the power is turned off or the system is rebooted. This includes the contents of memory (RAM) and other temporary data that are stored in caches or buffers. A memory dump captures this data and should be done before other less volatile data is collected, like hard drive images or log files, to ensure the most accurate and comprehensive capture of the system's state at the time of the incident.

Information Sharing and Analysis Centers (ISACs) are member-driven organizations, facilitated by the government, that gather and share information on cybersecurity threats, vulnerabilities, and incidents among their members. Engaging with an ISAC would enable the company to collaborate with others in the industry regarding emerging attacks and security threats.

OAuth, which stands for Open Authorization, is a standard for authorization that enables secure token-based access. It allows users to grant a web application access to their information on another web application without giving them the credentials for their account. OAuth is particularly useful for rapid authentication, flexible authorization, ease of deployment, and offers high functionality at a low cost, making it an ideal choice for new web-based applications. This approach is well-suited for situations where web applications need to interact with each other on behalf of the user, without sharing user's password, such as integrating a geolocation application with Facebook. OAuth uses tokens issued by an authorization server, providing restricted access to a user's data, which aligns with the objectives of rapid authentication, flexible authorization, ease of deployment, and cost-effectiveness​​.
