In terms of Internet Security, what is CEO Fraud?

• A Phishing email directed at a CEO or executive within a CEO's office
• When a CEO embezzles from their company
• A criminal who impersonates a supervisor or other high ranking individual in a phishing attempt
• A CEO who impersonates someone to attain private information 

EXPLANATION

Cyber criminals have developed a new attack called CEO Fraud, also known as Business Email Compromise (BEC).
In these attacks, a cyber criminal pretends to be a CEO or other senior executive from your organization. The criminals send an email to staff members like yourself that try to trick you into doing something you should not do. These types of attacks are extremely effective because the cyber criminals do their research. They search your organization’s website for information, such as where it is located, who your executives are, and other organizations you work with. The cyber criminals then learn everything they can about your coworkers on sites like LinkedIn, Facebook, or Twitter. Once they know your organization’s structure, they begin to research and target specific employees.

EXPLANATION

A Session Initiation Protocol (SIP) operates on the application layer. The basic purpose of SIP is to establish communications over the internet.
These communications might include video conferencing, online gaming or audio calls. It makes use of the idea of Voice over IP (VoIP) to achieve this purpose. It can create, modify and terminate these communication sessions. However, SIP also makes use of other transfer protocols such as TCP and UDP and does not operate entirely on its own.
