Malicious software can retrieve the data from the (supposedly) secure hardware – a large class of method used is the timing attack. [18] This is far more problematic to solve than a software bug, even within the operating system. Microsoft regularly deals with security issues through Windows Update.
An example of a physical security measure: a metal lock on the back of a personal computer to prevent hardware tampering. Computer security (also cybersecurity, digital security, or information technology (IT) security) is the protection of computer software, systems and networks from threats that can lead to unauthorized information disclosure, theft or damage to hardware, software, or data ...
Enterprise information security architecture is the practice of designing, constructing and maintaining information security strategies and policies in enterprise organisations. A subset of enterprise architecture , information security frameworks are often given their own dedicated resources in larger organisations and are therefore ...

The cost of making a copy of a software program is essentially zero, so per-use fees are perhaps unreasonable for open-source software. At one time, open-source software development was almost entirely volunteer-driven, and although this is true for many small projects, many alternative funding streams have been identified and employed for FOSS:
Information security is the practice of protecting information by mitigating information risks. It is part of information risk management. [1] It typically involves preventing or reducing the probability of unauthorized or inappropriate access to data or the unlawful use, disclosure, disruption, deletion, corruption, modification, inspection, recording, or devaluation of information.
Principles of Information Security is a textbook written by Michael Whitman and Herbert Mattord and published by Course Technology. [ 1 ] It is in widespread use in higher education in the United States as well as in many English -speaking countries.
A hardware security module (HSM) is a physical computing device that safeguards and manages digital keys for strong authentication and provides cryptoprocessing. These modules traditionally come in the form of a plug-in card or an external device that attaches directly to a computer or network server .
