Vulnerability Management
Vulnerability management is the "cyclical practice of identifying, classifying, prioritizing, remediating, and mitigating" software vulnerabilities. Vulnerability management is integral to computer security and network security, and must not be confused with vulnerability assessment. Vulnerabilities can be discovered with a vulnerability scanner, which analyzes a computer system in search of known vulnerabilities,Anna-Maija Juuso and Ari Takanen ''Unknown Vulnerability Management'', Codenomicon whitepaper, October 201 such as open ports, insecure software configurations, and susceptibility to malware infections. They may also be identified by consulting public sources, such as NVD, vendor specific security updates or subscribing to a commercial vulnerability alerting service. Unknown vulnerabilities, such as a zero-day, may be found with fuzz testing. Fuzzing is a cornerstone technique where random or semi-random input data is fed to programs to detect unexpected behavior. T ...

Software Vulnerability
Vulnerabilities are flaws or weaknesses in a system's design, implementation, or management that can be exploited by a malicious actor to compromise its security. Despite a system administrator's best efforts to achieve complete correctness, virtually all hardware and software contain Software bug, bugs where the system does not behave as expected. If the bug could enable an attacker to compromise the confidentiality, Data integrity, integrity, or availability of system resources, it can be considered a vulnerability. Insecure software development practices as well as design factors such as complexity can increase the burden of vulnerabilities. Vulnerability management is a process that includes identifying systems and prioritizing which are most important, scanning for vulnerabilities, and taking action to secure the system. Vulnerability management typically is a combination of remediation, mitigation, and acceptance. Vulnerabilities can be scored for severity according to the ...

Antivirus Software
Antivirus software (abbreviated to AV software), also known as anti-malware, is a computer program used to prevent, detect, and remove malware. Antivirus software was originally developed to detect and remove computer viruses, hence the name. However, with the proliferation of other malware, antivirus software started to protect against other computer threats. Some products also include protection from malicious URLs, spam, and phishing. History 1971–1980 period (pre-antivirus days) The first known computer virus appeared in 1971 and was dubbed the " Creeper virus". This computer virus infected Digital Equipment Corporation's ( DEC) PDP-10 mainframe computers running the TENEX operating system.From the first email to the first YouTube video: a d ...

Full Disclosure (computer Security)
In the field of computer security, independent researchers often discover flaws in software that can be abused to cause unintended behaviour; these flaws are called vulnerabilities. The process by which the analysis of these vulnerabilities is shared with third parties is the subject of much debate, and is referred to as the researcher's ''disclosure policy''. Full disclosure is the practice of publishing analysis of software vulnerabilities as early as possible, making the data accessible to everyone without restriction. The primary purpose of widely disseminating information about vulnerabilities is so that potential victims are as knowledgeable as those who attack them. In his 2007 essay on the topic, Bruce Schneier stated "Full disclosure – the practice of making the details of security vulnerabilities public – is a damned good idea. Public scrutiny is the only reliable way to improve security, while secrecy only makes us less secure." Leonard Rose, co-creator of an elec ...

Application Security
Application security (short AppSec) includes all tasks that introduce a secure software development life cycle to development teams. Its final goal is to improve security practices and, through that, to find, fix and preferably prevent security issues within applications. It encompasses the whole application life cycle from requirements analysis, design, implementation, verification as well as maintenance. Web application security is a branch of information security that deals specifically with the security of websites, web applications, and web services. At a high level, web application security draws on the principles of application security but applies them specifically to the internet and web systems. The application security also concentrates on mobile apps and their security which includes iOS and Android Applications Web Application Security Tools are specialized tools for working with HTTP traffic, e.g., Web application firewalls.

Project Complexity
Project complexity is the property of a project which makes it difficult to understand, foresee, and keep under control its overall behavior, even when given reasonably complete information about the project system. With a lens of systems thinking, project complexity can be defined as an intricate arrangement of the varied interrelated parts in which the elements can change and evolve constantly with an effect on the project objectives. The identification of complex projects is specifically important to multi-project engineering environments. The domain was introduced by D. Baccarini in 1996. Types of complexity Complexity can be: * Structural complexity (also known as detail complexity, or complicatedness), i.e. consisting of many varied interrelated parts. It is typically expressed in terms of size, variety, and interdependence of project components, and described by technological and organizational factors. * Dynamic complexity, which refers to phenomena, characteristics, and ...

Nassim Nicholas Taleb
Nassim Nicholas Taleb (; alternatively ''Nessim ''or'' Nissim''; born 12 September 1960) is a Lebanese-American essayist, mathematical statistician, former option trader, risk analyst, and aphorist. His work concerns problems of randomness, probability, complexity, and uncertainty. Taleb is the author of the ''Incerto'', a five-volume work on the nature of uncertainty published between 2001 and 2018 (notably, '' The Black Swan'' and '' Antifragile''). He has taught at several universities, serving as a Distinguished Professor of Risk Engineering at the New York University Tandon School of Engineering since September 2008. He has also been a practitioner of mathematical finance and is currently an adviser at Universa Investments. ''The Sunday Times'' described his 2007 book '' The Black Swan'' as one of the 12 most influential books since World War II. Taleb criticized risk management methods used by the finance industry and warned about financial crises, subsequently pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antifragility
Antifragility is a property of systems in which they increase in capability to thrive as a result of stressors, shocks, volatility, noise, mistakes, faults, attacks, or failures. The concept was developed by Nassim Nicholas Taleb in his book, '' Antifragile'', and in technical papers., As Taleb explains in his book, antifragility is fundamentally different from the concepts of resiliency (i.e. the ability to recover from failure) and robustness (that is, the ability to resist failure). The concept has been applied in risk analysis, physics, molecular biology, transportation planning, engineering, aerospace (NASA),Jones, Kennie H. "Antifragile Systems: An Enabler for System Engineering of Elegant Systems." (2015), NASA/ref> and computer science. Taleb defines it as follows in a letter to '' Nature (journal), Nature'' responding to an earlier review of his book in that journal: Antifragile versus robust/resilient In his book, Taleb stresses the differences between antifragile and ...

Redundancy (engineering)
In engineering and systems theory, redundancy is the intentional duplication of critical components or functions of a system with the goal of increasing reliability of the system, usually in the form of a backup or fail-safe, or to improve actual system performance, such as in the case of GNSS receivers, or multi-threaded computer processing. In many safety-critical systems, such as fly-by-wire and hydraulic systems in aircraft, some parts of the control system may be triplicated, which is formally termed triple modular redundancy (TMR). An error in one component may then be out-voted by the other two. In a triply redundant system, the system has three sub components, all three of which must fail before the system fails. Since each one rarely fails, and the sub components are designed to preclude common failure modes (which can then be modelled as independent failure), the probability of all three failing is calculated to be extraordinarily small; it is often outweighed ...

Social Engineering (security)
In the context of information security, social engineering is the use of psychological influence of people into performing actions or divulging Confidentiality, confidential information. This differs from psychological manipulation in that it doesn't need to be controlling, negative or a one-way transaction. Manipulation involves a zero-sum game where one party wins and the other loses while social engineering can be win-win for both parties. A type of confidence trick for the purpose of information gathering, fraud, or system access, it differs from a traditional "con" in the sense that it is often one of many steps in a more complex fraud scheme. It has also been defined as "any act that influences a person to take an action that may or may not be in their best interests." Research done in 2020 has indicated that social engineering will be one of the most prominent challenges of the upcoming decade. Having proficiency in social engineering will be increasingly important for orga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
User (computing)
A user is a person who uses a computer or network service. A user often has a user account and is identified to the system by a username (or user name). Some software products provide services to other systems and have no direct end users. End user End users are the ultimate human users (also referred to as operators) of a software product. The end user stands in contrast to users who support or maintain the product such as sysops, database administrators and computer technicians. The term is used to abstract and distinguish those who only use the software from the developers of the system, who enhance the software for end users. In user-centered design, it also distinguishes the software operator from the client who pays for its development and other stakeholders who may not directly use the software, but help establish its requirements. This abstraction is primarily useful in designing the user interface, and refers to a relevant subset of characteristics t ...

Patch (computing)
A patch is data that is intended to be used to modify an existing software resource such as a computer program, program or a computer file, file, often to fix software bug, bugs and security vulnerability, security vulnerabilities. A patch may be created to improve functionality, usability, or Computer performance, performance. A patch is typically provided by a vendor for updating the software that they provide. A patch may be created manually, but commonly it is created via a tool that compares two versions of the resource and generates data that can be used to transform one to the other. Typically, a patch needs to be applied to the specific version of the resource it is intended to modify, although there are exceptions. Some patching tools can detect the version of the existing resource and apply the appropriate patch, even if it supports multiple versions. As more patches are released, their cumulative size can grow significantly, sometimes exceeding the size of the resource ...
