  2. Computer security - Wikipedia

    en.wikipedia.org/wiki/Computer_security

    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 ...

  3. Software security assurance - Wikipedia

    en.wikipedia.org/wiki/Software_Security_Assurance

    Software Security Assurance (SSA) is the process of ensuring that software is designed to operate at a level of security that is consistent with the potential harm that could result from the loss, inaccuracy, alteration, unavailability, or misuse of the data and resources that it uses, controls, and protects.

  4. Computer security model - Wikipedia

    en.wikipedia.org/wiki/Computer_security_model

    A computer security model is a scheme for specifying and enforcing security policies. A security model may be founded upon a formal model of access rights, a model of computation, a model of distributed computing, or no particular theoretical grounding at all. A computer security model is implemented through a computer security policy.

  5. Secure by design - Wikipedia

    en.wikipedia.org/wiki/Secure_by_design

    Secure by design, in software engineering, means that software products and capabilities have been designed to be foundationally secure.. Alternate security strategies, tactics and patterns are considered at the beginning of a software design, and the best are selected and enforced by the architecture, and they are used as guiding principles for developers. [1]

  6. Protection ring - Wikipedia

    en.wikipedia.org/wiki/Protection_ring

    In computer science, hierarchical protection domains, [1] [2] often called protection rings, are mechanisms to protect data and functionality from faults (by improving fault tolerance) and malicious behavior (by providing computer security). Computer operating systems provide different levels of access to resources. A protection ring is one of ...

  7. Security information and event management - Wikipedia

    en.wikipedia.org/wiki/Security_information_and...

    Security as a service : These security services often include authentication, anti-virus, anti-malware/spyware, intrusion detection, penetration testing and security event management, among others. In practice many products in this area will have a mix of these functions, so there will often be some overlap – and many commercial vendors also ...

  8. Trusted execution environment - Wikipedia

    en.wikipedia.org/wiki/Trusted_execution_environment

    With the rise of software assets and reuses, modular programming is the most productive process to design software architecture, by decoupling the functionalities into small independent modules. As each module contains everything necessary to execute its desired functionality, the TEE allows the organization of the complete system featuring a ...

  9. Object-capability model - Wikipedia

    en.wikipedia.org/wiki/Object-capability_model

    Computer scientist E. Dean Tribble stated that in smart contracts, identity-based access control did not support well dynamically changing permissions, compared to the object-capability model. He analogized the ocap model with giving a valet the key to one's car, without handing over the right to car ownership.
