  2. Secure coding - Wikipedia

    en.wikipedia.org/wiki/Secure_coding

    For example, if there are 8 slots to store items in, there will be a problem if there is an attempt to store 9 items. In computer memory the overflowed data may overwrite data in the next location which can result in a security vulnerability (stack smashing) or program termination (segmentation fault). [1]

  3. Access control matrix - Wikipedia

    en.wikipedia.org/wiki/Access_Control_Matrix

    In this matrix example there exist two processes, two assets, a file, and a device. The first process is the owner of asset 1, has the ability to execute asset 2, read the file, and write some information to the device, while the second process is the owner of asset 2 and can read asset 1.

  4. Confused deputy problem - Wikipedia

    en.wikipedia.org/wiki/Confused_deputy_problem

    In information security, a confused deputy is a computer program that is tricked by another program (with fewer privileges or less rights) into misusing its authority on the system. It is a specific type of privilege escalation. [1] The confused deputy problem is often cited as an example of why capability-based security is important.

  5. Defensive programming - Wikipedia

    en.wikipedia.org/wiki/Defensive_programming

    Secure programming is the subset of defensive programming concerned with computer security. Security is the concern, not necessarily safety or availability (the software may be allowed to fail in certain ways). As with all kinds of defensive programming, avoiding bugs is a primary objective; however, the motivation is not as much to reduce the ...

    A host of security software vendors release anti-hacking products for use on home computers. U.S. President Bill Clinton announces a $1.46 billion initiative to improve government computer security. The plan would establish a network of intrusion detection monitors for certain federal agencies and encourage the private sector to do the same.

  7. List of algorithms - Wikipedia

    en.wikipedia.org/wiki/List_of_algorithms

    An algorithm is fundamentally a set of rules or defined procedures that is typically designed and used to solve a specific problem or a broad set of problems.. Broadly, algorithms define process(es), sets of rules, or methodologies that are to be followed in calculations, data processing, data mining, pattern recognition, automated reasoning or other problem-solving operations.

  8. 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 ...

  9. ABA problem - Wikipedia

    en.wikipedia.org/wiki/ABA_problem

    A common case of the ABA problem is encountered when implementing a lock-free data structure. If an item is removed from the list, deleted, and then a new item is allocated and added to the list, it is common for the allocated object to be at the same location as the deleted object due to MRU memory allocation. A pointer to the new item is thus ...
