information security definition

Identity theft is the attempt to act as someone else usually to obtain that person's personal information or to take advantage of their access to vital information through social engineering. In 2011, The Open Group published the information security management standard O-ISM3. Roer & Petric (2017) identify seven core dimensions of information security culture in organizations:[86], Andersson and Reimers (2014) found that employees often do not see themselves as part of the organization Information Security "effort" and often take actions that ignore organizational information security best interests. The change management process is as follows[67]. Some of the most common threats today are software attacks, theft of intellectual property, identity theft, theft of equipment or information, sabotage, and information extortion. Infosec pros do you know how to handle the top 10 types of information security threats you're most likely to encounter? The International Organization for Standardization (ISO) is a consortium of national standards institutes from 157 countries, coordinated through a secretariat in Geneva, Switzerland. The field of information security has grown and evolved significantly in recent years. Information security is designed and implemented to protect the print, electronic and other private, sensitive and personal data from unauthorized persons. The BCM should be included in an organizations risk analysis plan to ensure that all of the necessary business functions have what they need to keep going in the event of any type of threat to any business function. Information security – maintaining, the confidentiality, availability and integrity of corporate information assets and intellectual property – is more important for the long-term success of organisations than traditional, physical and tangible assets. The bank teller checks the license to make sure it has John Doe printed on it and compares the photograph on the license against the person claiming to be John Doe. For example, the British Government codified this, to some extent, with the publication of the Official Secrets Act in 1889. Such incidents can threaten health, violate privacy, disrupt business, damage assets and facilitate other crimes such as fraud. The Federal Financial Institutions Examination Council's (FFIEC) security guidelines for auditors specifies requirements for online banking security. Even though two employees in different departments have a top-secret clearance, they must have a need-to-know in order for information to be exchanged. Information security includes those measures necessary to detect, document, and counter such threats. Information security incident. In contrast to a metal chain, which is famously only as strong as its weakest link, the defense in depth strategy aims at a structure where, should one defensive measure fail, other measures will continue to provide protection.[52]. The law forces these and other related companies to build, deploy and test appropriate business continuity plans and redundant infrastructures. Calculate the impact that each threat would have on each asset. This is often described as the "reasonable and prudent person" rule. Howeve [70], Whereas BCM takes a broad approach to minimizing disaster-related risks by reducing both the probability and the severity of incidents, a disaster recovery plan (DRP) focuses specifically on resuming business operations as quickly as possible after a disaster. Such devices can range from non-networked standalone devices as simple as calculators, to networked mobile computing devices such as smartphones and tablet computers. Research has shown that the most vulnerable point in most information systems is the human user, operator, designer, or other human. Identification of assets and estimating their value. Need-to-know helps to enforce the confidentiality-integrity-availability triad. Other examples of administrative controls include the corporate security policy, password policy, hiring policies, and disciplinary policies. In the context of information security, the impact is a loss of availability, integrity, and confidentiality, and possibly other losses (lost income, loss of life, loss of real property). When an end user reports information or an admin notices irregularities, an investigation is launched. Information security, also known as infosec is the process of securing data and information secure from any kind of violations in the form of theft, abuse or loss. The U.S. Treasury's guidelines for systems processing sensitive or proprietary information, for example, states that all failed and successful authentication and access attempts must be logged, and all access to information must leave some type of audit trail.[56]. (ISO/IEC 27000:2009), "The protection of information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction in order to provide confidentiality, integrity, and availability." Information security (or “InfoSec”) is another way of saying “data security.” So if you are an information security specialist, your concern is for the confidentiality, integrity, and availability of your data. Note: This template roughly follows the 2012. When a threat does use a vulnerability to inflict harm, it has an impact. Below is a partial listing of governmental laws and regulations in various parts of the world that have, had, or will have, a significant effect on data processing and information security. Definition - What does Information Security (IS) mean? The CIA triad of confidentiality, integrity, and availability is at the heart of information security. The responsibility of the change review board is to ensure the organization's documented change management procedures are followed. An applications programmer should not also be the server administrator or the database administrator; these roles and responsibilities must be separated from one another. The Enigma Machine, which was employed by the Germans to encrypt the data of warfare and was successfully decrypted by Alan Turing, can be regarded as a striking example of creating and using secured information. Both disciplines involve a variety of similar issues, including risk management, cyber security, corporate governance, compliance, auditing, business continuity, disaster recovery, forensic science, security engineering, and criminology. Although related, information assurance and information security are two different disciplines. The Institute of Information Security Professionals (IISP) is an independent, non-profit body governed by its members, with the principal objective of advancing the professionalism of information security practitioners and thereby the professionalism of the industry as a whole. They must be protected from unauthorized disclosure and destruction and they must be available when needed. Older, less secure applications such as Telnet and File Transfer Protocol (FTP) are slowly being replaced with more secure applications such as Secure Shell (SSH) that use encrypted network communications. Information security policy should be based on a combination of appropriate legislation, such as FISMA; applicable standards, such as NIST Federal Inf… Information security includes those measures necessary to detect, document, and counter such threats. It’s important because government has a duty to protect service users’ data. Next, develop a classification policy. The non-discretionary approach consolidates all access control under a centralized administration. [51], Information security must protect information throughout its lifespan, from the initial creation of the information on through to the final disposal of the information. [33][34][35] Neither of these models are widely adopted. Information security definition Information security is a set of practices designed to keep personal data secure from unauthorized access and alteration during storing or transmitting from one place to another. [26] The academic disciplines of computer security and information assurance emerged along with numerous professional organizations, all sharing the common goals of ensuring the security and reliability of information systems. Include: people, buildings, hardware, software, data (electronic, print, other), supplies. In recent years these terms have found their way into the fields of computing and information security. Change management is a tool for managing the risks introduced by changes to the information processing environment. This means the computing systems used to store and process the information, the security controls used to protect it, and the communication channels used to access it must be functioning correctly. Authentication is the act of verifying a claim of identity. Usernames and passwords have served their purpose, but they are increasingly inadequate. electronic or physical, tangible (e.g. Information security threats come in many different forms. Explore Cisco Secure. Julius Caesar is credited with the invention of the Caesar cipher c. 50 B.C., which was created in order to prevent his secret messages from being read should a message fall into the wrong hands. information security. See also communications security; computer security; information security; information system. The information must be protected while in motion and while at rest. The US National Institute of Standards and Technology (NIST) is a non-regulatory federal agency within the U.S. Department of Commerce. In fact, information security has been around ever since we have had information to protect. Identification is an assertion of who someone is or what something is. First, the process of risk management is an ongoing, iterative process. Second, the choice of countermeasures (controls) used to manage risks must strike a balance between productivity, cost, effectiveness of the countermeasure, and the value of the informational asset being protected. One of management's many responsibilities is the management of risk. It ranges from technical configurations to legal and policy work. Sabotage usually consists of the destruction of an organization's website in an attempt to cause loss of confidence on the part of its customers. Logical controls (also called technical controls) use software and data to monitor and control access to information and computing systems. This step can also be used to process information that is distributed from other entities who have experienced a security event. The username is the most common form of identification on computer systems today and the password is the most common form of authentication. (McDermott and Geer, 2001), "A well-informed sense of assurance that information risks and controls are in balance." [28], The triad seems to have first been mentioned in a NIST publication in 1977.[29]. [47] The reality of some risks may be disputed. From each of these derived guidelines and practices. How to use security in a sentence. [38] This means that data cannot be modified in an unauthorized or undetected manner. Some kinds of changes are a part of the everyday routine of information processing and adhere to a predefined procedure, which reduces the overall level of risk to the processing environment. We need to start with a definition. (This is often referred to as the “CIA.”) Ensuring availability also involves preventing denial-of-service attacks, such as a flood of incoming messages to the target system, essentially forcing it to shut down.[39]. This is accomplished through planning, peer review, documentation and communication. Should confidential information about a business' customers or finances or new product line fall into the hands of a competitor or a black hat hacker, a business and its customers could suffer widespread, irreparable financial loss, as well as damage to the company's reputation. It is not, for instance, sufficient to show that the message matches a digital signature signed with the sender's private key, and thus only the sender could have sent the message, and nobody else could have altered it in transit (data integrity). In the field of information security, Harris[58] ISO is the world's largest developer of standards. Furthermore, these processes have limitations as security breaches are generally rare and emerge in a specific context which may not be easily duplicated. For any given risk, management can choose to accept the risk based upon the relative low value of the asset, the relative low frequency of occurrence, and the relative low impact on the business. Behaviors: Actual or intended activities and risk-taking actions of employees that have direct or indirect impact on information security. Not every change needs to be managed. Information security's primary focus is the balanced protection of the confidentiality, integrity and availability of data (also known as the CIA triad) while maintaining a focus on efficient policy implementation, all without hampering organization productivity. Additional insight into defense in depth can be gained by thinking of it as forming the layers of an onion, with data at the core of the onion, people the next outer layer of the onion, and network security, host-based security and application security forming the outermost layers of the onion. However, debate continues about whether or not this CIA triad is sufficient to address rapidly changing technology and business requirements, with recommendations to consider expanding on the intersections between availability and confidentiality, as well as the relationship between security and privacy. The objectives of change management are to reduce the risks posed by changes to the information processing environment and improve the stability and reliability of the processing environment as changes are made. Effective policies ensure that people are held accountable for their actions. Information security policy is a set of policies issued by an organization to ensure that all information technology users within the domain of the organization or its networks comply with rules and guidelines related to the security of the information stored digitally at any point in the network or within the organization's boundaries of authority. The remaining risk is called "residual risk.". The European Telecommunications Standards Institute standardized a catalog of information security indicators, headed by the Industrial Specification Group (ISG) ISI. Describing more than simply how security aware employees are, information security culture is the ideas, customs, and social behaviors of an organization that impact information security in both positive and negative ways. (Anderson, J., 2003), "Information security is the protection of information and minimizes the risk of exposing information to unauthorized parties." Organizations have a responsibility with practicing duty of care when applying information security. The theft of intellectual property has also been an extensive issue for many businesses in the information technology (IT) field. Thus, any process and countermeasure should itself be evaluated for vulnerabilities. Information security is composed of computer security and communications security. In information security, confidentiality "is the property, that information is not made available or disclosed to unauthorized individuals, entities, or processes. The Internet Society is a professional membership society with more than 100 organizations and over 20,000 individual members in over 180 countries. The ISOC hosts the Requests for Comments (RFCs) which includes the Official Internet Protocol Standards and the RFC-2196 Site Security Handbook. [54], The type of information security classification labels selected and used will depend on the nature of the organization, with examples being:[53]. An important logical control that is frequently overlooked is the principle of least privilege, which requires that an individual, program or system process not be granted any more access privileges than are necessary to perform the task. However, the implementation of any standards and guidance within an entity may have limited effect if a culture of continual improvement isn't adopted. IT security maintains the integrity and confidentiality of sensitive information while blocking access to hackers. information security The protection of information and information systems against unauthorized access or modification of information, whether in storage, processing, or transit, and against denial of service to authorized users. The fault for these violations may or may not lie with the sender, and such assertions may or may not relieve the sender of liability, but the assertion would invalidate the claim that the signature necessarily proves authenticity and integrity. This happens when employees' job duties change, employees are promoted to a new position, or employees are transferred to another department. InfoSec provides coverage for cryptography, mobile computing, social media, as well as infrastructure and networks containing private, financial, and corporate information. If the photo and name match the person, then the teller has authenticated that John Doe is who he claimed to be. [63], In this phase, the IRT works to isolate the areas that the breach took place to limit the scope of the security event. security noun (PROTECTION) B1 [ U ] protection of a person, building, organization, or country against threats such as crime or attacks by foreign countries: The station was closed for two hours because of … A set of security goals, identified as a result of a threat analysis, should be revised periodically to ensure its adequacy and conformance with the evolving environment. This standardization may be further driven by a wide variety of laws and regulations that affect how data is accessed, processed, stored, transferred and destroyed. Information security management (ISM) describes controls that an organization needs to implement to ensure that it is sensibly protecting the confidentiality, availability, and … This team should also keep track of trends in cybersecurity and modern attack strategies. B., McDermott, E., & Geer, D. (2001). Information security is the theory and practice of only allowing access to information to people in an organization who are authorized to see it.
