    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).

  3. Capability-based security - Wikipedia

    en.wikipedia.org/wiki/Capability-based_security

    A forgeable reference (for example, a path name) identifies an object, but does not specify which access rights are appropriate for that object and the user program which holds that reference. Consequently, any attempt to access the referenced object must be validated by the operating system, based on the ambient authority of the requesting ...

  4. 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 ...

  5. Language-based security - Wikipedia

    en.wikipedia.org/wiki/Language-based_security

    In computer science, language-based security (LBS) is a set of techniques that may be used to strengthen the security of applications on a high level by using the properties of programming languages. LBS is considered to enforce computer security on an application-level, making it possible to prevent vulnerabilities which traditional operating ...

  6. Return-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Return-oriented_programming

    A number of techniques have been proposed to subvert attacks based on return-oriented programming. [17] Most rely on randomizing the location of program and library code, so that an attacker cannot accurately predict the location of instructions that might be useful in gadgets and therefore cannot mount a successful return-oriented programming ...

    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 ...

    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.
