Information security is the practice of protecting information by mitigating information risks. It is part of information risk management. 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. It also involves actions intended to reduce the adverse impacts of such incidents. Protected information may take any form, e.g., electronic or physical, tangible, or intangible. Information security's primary focus is the balanced protection of data confidentiality, integrity, and availability while maintaining a focus on efficient policy implementation, all without hampering organization productivity. This is largely achieved through a structured risk management process.
COBIT is a framework created by ISACA for information technology (IT) management and IT governance.
ISACA is an international professional association focused on IT governance. On its IRS filings, it is known as the Information Systems Audit and Control Association, although ISACA now goes by its acronym only. ISACA currently offers 8 certification programs, as well as other micro-certificates.
Information security standards are techniques generally outlined in published materials that attempt to protect a user's or organization's cyber environment. This environment includes users themselves, networks, devices, all software, processes, information in storage or transit, applications, services, and systems that can be connected directly or indirectly to networks.
A chief information security officer (CISO) is a senior-level executive within an organization responsible for establishing and maintaining the enterprise vision, strategy, and program to ensure information assets and technologies are adequately protected. The CISO directs staff in identifying, developing, implementing, and maintaining processes across the enterprise to reduce information and information technology (IT) risks. They respond to incidents, establish appropriate standards and controls, manage security technologies, and direct the establishment and implementation of policies and procedures. The CISO is also usually responsible for information-related compliance. The CISO is also responsible for protecting proprietary information and assets of the company, including the data of clients and consumers. CISO works with other executives to make sure the company is growing in a responsible and ethical manner.
Information security management (ISM) defines and manages controls that an organization needs to implement to ensure that it is sensibly protecting the confidentiality, availability, and integrity of assets from threats and vulnerabilities. The core of ISM includes information risk management, a process that involves the assessment of the risks an organization must deal with in the management and protection of assets, as well as the dissemination of the risks to all appropriate stakeholders. This requires proper asset identification and valuation steps, including evaluating the value of confidentiality, integrity, availability, and replacement of assets. As part of information security management, an organization may implement an information security management system and other best practices found in the ISO/IEC 27001, ISO/IEC 27002, and ISO/IEC 27035 standards on information security.
ISO/IEC 27002 is an information security standard published by the International Organization for Standardization (ISO) and by the International Electrotechnical Commission (IEC), titled Information security, cybersecurity and privacy protection — Information security controls.
The ISO/IEC 27000 family comprises information security standards published jointly by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).
MEHARI is a free, open-source information risk analysis assessment and risk management method, for the use of information security professionals.
ISO/IEC 27005 "Information technology — Security techniques — Information security risk management" is an international standard published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) providing good practice guidance on managing risks to information. It is a core part of the ISO/IEC 27000-series of standards, commonly known as ISO27k.
Information technology risk, IT risk, IT-related risk, or cyber risk is any risk relating to information technology. While information has long been appreciated as a valuable and important asset, the rise of the knowledge economy and the Digital Revolution has led to organizations becoming increasingly dependent on information, information processing and especially IT. Various events or incidents that compromise IT in some way can therefore cause adverse impacts on the organization's business processes or mission, ranging from inconsequential to catastrophic in scale.
NIST Special Publication 800-53 is an information security standard that provides a catalog of privacy and security controls for information systems. Originally intended for U.S. federal agencies except those related to national security, since the 5th revision it is a standard for general usage. It is published by the National Institute of Standards and Technology, which is a non-regulatory agency of the United States Department of Commerce. NIST develops and issues standards, guidelines, and other publications to assist federal agencies in implementing the Federal Information Security Modernization Act of 2014 (FISMA) and to help with managing cost effective programs to protect their information and information systems.
Security information and event management (SIEM) is a field within computer security that combines security information management (SIM) and security event management (SEM) to enable real-time analysis of security alerts generated by applications and network hardware. SIEM systems are central to the operation of security operations centers (SOCs), where they are employed to detect, investigate, and respond to security incidents. SIEM technology collects and aggregates data from various systems, allowing organizations to meet compliance requirements while safeguarding against threats.
The Risk Management Framework (RMF) is a United States federal government guideline, standard, and process for managing risk to help secure information systems, developed by the National Institute of Standards and Technology (NIST). The RMF provides a structured process that integrates information security, privacy, and risk management activities into the system development life cycle.
IT risk management is the application of risk management methods to information technology in order to manage IT risk. Various methodologies exist to manage IT risks, each involving specific processes and steps.
ISO/IEC 27001 is an international standard to manage information security. The standard was originally published jointly by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) in 2005, revised in 2013, and again most recently in 2022. There are also numerous recognized national variants of the standard. It details requirements for establishing, implementing, maintaining and continually improving an information security management system (ISMS) – the aim of which is to help organizations make the information assets they hold more secure. Organizations that meet the standard's requirements can choose to be certified by an accredited certification body following successful completion of an audit. A SWOT analysis of the ISO/IEC 27001 certification process was conducted in 2020.
The NIST Cybersecurity Framework (CSF) is a set of voluntary guidelines designed to help organizations assess and improve their ability to prevent, detect, and respond to cybersecurity risks. Developed by the U.S. National Institute of Standards and Technology (NIST), the framework was initially published in 2014 for critical infrastructure sectors but has since been widely adopted across various industries, including government and private enterprises globally. The framework integrates existing standards, guidelines, and best practices to provide a structured approach to cybersecurity risk management.
The Center for Internet Security (CIS) is a US 501(c)(3) nonprofit organization, formed in October 2000. Its mission statement professes that the function of CIS is to " help people, businesses, and governments protect themselves against pervasive cyber threats."
This is a list of cybersecurity information technology. Cybersecurity is security as it is applied to information technology. This includes all technology that stores, manipulates, or moves data, such as computers, data networks, and all devices connected to or included in networks, such as routers and switches. All information technology devices and facilities need to be secured against intrusion, unauthorized use, and vandalism. Additionally, the users of information technology should be protected from theft of assets, extortion, identity theft, loss of privacy and confidentiality of personal information, malicious mischief, damage to equipment, business process compromise, and the general activity of cybercriminals. The public should be protected against acts of cyberterrorism, such as the compromise or loss of the electric power grid.
Cybersecurity engineering is a tech discipline focused on the protection of systems, networks, and data from unauthorized access, cyberattacks, and other malicious activities. It applies engineering principles to the design, implementation, maintenance, and evaluation of secure systems, ensuring the integrity, confidentiality, and availability of information.
