Whois & Analysis for sans.org

The SANS Institute (officially the Escal Institute of Advanced Technologies) is a private U.S. for-profit company founded in 1989 that specializes in information security and cybersecurity training.

Topics available for training include cyber and network defenses, penetration testing, incident response, digital forensics, and audit.

The information security courses are developed through a consensus process involving administrators, security managers, and information security professionals.

The courses cover security fundamentals and technical aspects of information security.

The Institute has been recognized for its training programs and certification programs.

SANS stands for SysAdmin, Audit, Network and Security.

Information security, sometimes shortened to InfoSec, is the practice of preventing unauthorized access, use, disclosure, disruption, modification, inspection, recording or destruction of information.

It is a general term that can be used regardless of the form the data may take (e.g. electronic, physical).

Computer security, also known as cybersecurity or IT security, is the protection of computer systems from the theft or damage to the hardware, software or the information on them, as well as from disruption or misdirection of the services they provide.

Immersion into virtual reality is a perception of being physically present in a non-physical world.

The perception is created by surrounding the user of the VR system in images, sound or other stimuli that provide an engrossing total environment.

Asymmetric multiprocessing (AMP) was the only method for handling multiple CPUs before symmetric multiprocessing (SMP) was available.

It has also been used to provide less expensive options on systems where SMP was available.

Additionally, AMP is used in applications that are dedicated, such as embedded systems, when individual processors can be dedicated to specific tasks at design time.

In an asymmetric multiprocessing system, not all CPUs are treated equally; for example, a system might only allow (either at the hardware or operating system level) one CPU to execute operating system code or might only allow one CPU to perform I/O operations.

Other AMP systems would allow any CPU to execute operating system code and perform I/O operations, so that they were symmetric with regard to processor roles, but attached some or all peripherals to particular CPUs, so that they were asymmetric with regard to peripheral attachment.
