In the first draft version [8] of the FIPS 140-3 standard, NIST introduced a new software security section, one additional level of assurance (Level 5) and new Simple Power Analysis (SPA) and Differential Power Analysis (DPA) requirements. The draft issued on 11 Sep 2009, however, reverted to four security levels and limits the security levels ...
TEMPEST (Telecommunications Electronics Materials Protected from Emanating Spurious Transmissions [1]) is a U.S. National Security Agency specification and a NATO certification [2] [3] referring to spying on information systems through leaking emanations, including unintentional radio or electrical signals, sounds, and vibrations.
The system power consumption is a sum of the power ratings for all of the components of the computer system that draw on the power supply. Some graphics cards (especially multiple cards) and large groups of hard drives can place very heavy demands on the 12 V lines of the PSU, and for these loads, the PSU's 12 V rating is crucial.
Data requirements can also be identified in the contract via special contract clauses (e.g., DFARS), which define special data provisions such as rights in data, warranty, etc. SOW guidance of MIL-HDBK-245D describes the desired relationship: "Work requirements should be specified in the SOW, and all data requirements for delivery, format, and ...
Typical computer power supplies may have power factors as low as 0.5 to 0.6. [14] The higher power factor reduces the peak current draw, reducing load on the circuit or on an uninterruptible power supply. Reducing the heat output of the computer helps reduce noise, since fans do not have to spin as fast to cool the computer. Reduced heat and ...
A power-on self-test (POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. [ 1 ] POST processes may set the initial state of the device from firmware and detect if any hardware components are non-functional.
To be used efficiently, all computer software needs certain hardware components or other software resources to be present on a computer. [1] These prerequisites are known as (computer) system requirements and are often used as a guideline as opposed to an absolute rule. Most software defines two sets of system requirements: minimum and recommended.
A technical standard is an established norm or requirement for a repeatable technical task which is applied to a common and repeated use of rules, conditions, guidelines or characteristics for products or related processes and production methods, and related management systems practices.
