Bridge Data link layer device developed in the early 1980s to connect local area networks (LANs) or create two separate LAN or wide area network (WAN) network segments from a single segment to reduce collision domains Scope Note: A bridge acts as a

store-and-forward device in moving frames toward their destination. This is achieved by analyzing the MAC header of a data packet, which represents the hardware address of an NIC.


Bring your own device (BYOD) An enterprise policy used to permit partial or full integration of

user-owned mobile devices for business purposes DUTCH: Bring your own device (BYOD)

Broadband Multiple channels are formed by dividing the transmission medium into discrete frequency segments. Scope Note: Broadband generally requires the use of a modem.

DUTCH: Breedband

Broadcast A method to distribute information to multiple recipients simultaneously

DUTCH: Distributie

Brouter Device that performs the functions of both a bridge and a router Scope Note: A brouter operates at both the data link and the network layers. It connects same data link type LAN segments as well as different data link ones, which is a significant advantage. Like a bridge, it forwards packets based on the data link layer address to a different network of the same type. Also, whenever required, it processes and forwards messages to a different data link type network based on the network protocol address. When connecting same data link type networks, it is as fast as a bridge and is able to connect different data link type networks.

DUTCH: Brouter

Browser A computer program that enables the user to retrieve information that has been made publicly available on the Internet; also, that permits multimedia (graphics) applications on the World Wide Web

DUTCH: Browser

DUTCH: begrotingsafdeling

Buffer Memory reserved to temporarily hold data to offset differences between the operating speeds of different devices, such as a printer and a computer Scope Note: In a program, buffers are reserved areas of random access memory (RAM) that hold data while they are being processed.

DUTCH: Buffer

Buffer overflow Occurs when a program or process tries to store more data in a buffer (temporary data storage area) than it was intended to hold Scope Note: Since buffers are created to contain a finite amount of data, the extra information—which has to go somewhere—can overflow into adjacent buffers, corrupting or overwriting the valid data held in them.

Although it may occur accidentally through programming error, buffer overflow is an increasingly common type of security attack on data integrity. In buffer overflow attacks, the extra data may contain codes designed to trigger specific actions, in effect sending new instructions to the attacked computer that could, for example, damage the user's files, change data, or disclose confidential information. Buffer overflow attacks are said to have arisen because the C programming language supplied the framework, and poor programming practices supplied the vulnerability.

DUTCH: Buffer overflow

Bulk data transfer A data recovery strategy that includes a recovery from complete backups that are physically shipped offsite once a week Scope Note: Specifically, logs are batched electronically several times daily, and then loaded into a tape library located at the same facility as the planned recovery.

Bus Common path or channel between hardware devices Scope Note: Can be located between components internal to a computer or between external computers in a communication network.

DUTCH: bus

Bus configuration All devices (nodes) are linked along one communication line where transmissions are received by all attached nodes. Scope Note: This architecture is reliable in very small networks, as well as easy to use and understand. This configuration requires the least amount of cable to connect the computers together and, therefore, is less expensive than other cabling arrangements. It is also easy to extend, and two cables can be easily joined with a connector to make a longer cable for more computers to join the network. A repeater can also be used to extend a bus configuration. DUTCH: busconfiguratie

Business-to-business Transactions in which the acquirer is an enterprise or an individual operating in the ambits of his/her professional activity. In this case, laws and regulations related to consumer protection are not applicable. Scope Note: The contract’s general terms should be communicated to the other party and specifically approved. Some companies require the other party to fill out check-boxes where there is a description such as "I specifically approve the clauses" This is not convincing; the best solution is the adoption of a digital signature scheme, which allows the approval of clauses and terms with the non-repudiation condition.

DUTCH: business-to-business (B2B)

Business-to-consumer Selling processes in which the involved parties are the enterprise, which offers goods or services, and a consumer. In this case there is comprehensive legislation that protects the consumer.

Scope Note: Comprehensive legislation includes: Regarding contracts established outside the merchant’s property (such as the right to end the contract with full refund or the return policy for goods)

Regarding distance contracts (such as rules that establish how a contract should be written, specific clauses and the need to transmit to the consumer and approve it) Regarding electronic form of the contract (such as on the Internet, the possibility for the consumer to exit from the procedure without having his/her data recorded)

DUTCH: business-to-consumer (B2C)

business function or individual level that has the potential, or is required, to contribute to a business outcome and to create value

DUTCH: vaardigheid

Capability Maturity Model (CMM) 1. Contains the essential elements of effective processes for one or more disciplines.

It also describes an evolutionary improvement path from ad hoc, immature processes to disciplined, mature processes with improved quality and effectiveness. 2.

CMM for software, from the Software Engineering Institute (SEI), is a model used by many enterprises to identify best practices useful in helping them assess and increase the maturity of their software development processes Scope Note: CMM ranks software development enterprises according to a hierarchy of five process maturity levels. Each level ranks the development environment according to its capability of producing quality software. A set of standards is associated with each of the five levels. The standards for level one describe the most immature or chaotic processes and the standards for level five describe the most mature or quality processes.

A maturity model that indicates the degree of reliability or dependency the business can place on a process achieving the desired goals or objectives

A collection of instructions that an enterprise can follow to gain better control over its software development process

DUTCH: Capability maturity model (CMM)

Capacity stress testing Testing an application with large quantities of data to evaluate its performance during peak periods. Also called volume testing

DUTCH: Kapitaaluitgaven (CAPEX)

Card swipe A physical control technique that uses a secured card or ID to gain access to a highly sensitive location. Scope Note: If built correctly, card swipes act as a preventive control over physical access to those sensitive locations. After a card has been swiped, the application attached to the physical card swipe device logs all card users who try to access the secured location. The card swipe device prevents unauthorized access and logs all attempts to enter the secured location.

DUTCH: Certificaatautoriteit (CA)

Certificate revocation list (CRL) An instrument for checking the continued validity of the certificates for which the certification authority (CA) has responsibility Scope Note: The CRL details digital certificates that are no longer valid. The time gap between two updates is very critical and is also a risk in digital certificates verification.

DUTCH: Certification revocation list (CRL)

Certification practice statement (CPS) A detailed set of rules governing the certificate authority's operations. It provides an understanding of the value and trustworthiness of certificates issued by a given certificate authority (CA). Scope Note: In terms of the controls that an enterprise observes, the method it uses to validate the authenticity of certificate applicants and the CA's expectations of how its certificates may be used DUTCH: certificatie praktijk verklaring (CPS)

Chain of custody A legal principle regarding the validity and integrity of evidence. It requires accountability for anything that will be used as evidence in a legal proceeding to ensure that it can be accounted for from the time it was collected until the time it is presented in a court of law. Scope Note: Includes documentation as to who had access to the evidence and when, as well as the ability to identify evidence as being the exact item that was recovered or tested. Lack of control over evidence can lead to it being discredited.

Chain of custody depends on the ability to verify that evidence could not have been tampered with. This is accomplished by sealing off the evidence, so it cannot be changed, and providing a documentary record of custody to prove that the evidence was at all times under strict control and not subject to tampering.

DUTCH: Ketenbeheer (chain of custody)

Challenge/response token A method of user authentication that is carried out through use of the Challenge Handshake Authentication Protocol (CHAP) Scope Note: When a user tries to log into the server using CHAP, the server sends the user a "challenge," which is a random value. The user enters a password, which is used as an encryption key to encrypt the "challenge" and return it to the server. The server is aware of the password. It, therefore, encrypts the "challenge" value and compares it with the value received from the user. If the values match, the user is authenticated. The challenge/response activity continues throughout the session and this protects the session from password sniffing attacks. In addition, CHAP is not vulnerable to "man-in-the-middle" attacks because the challenge value is a random value that changes on each access attempt.

DUTCH: Challenge/response-token

Change management A holistic and proactive approach to managing the transition from a current to a desired organizational state, focusing specifically on the critical human or "soft" elements of change Scope Note: Includes activities such as culture change (values, beliefs and attitudes), development of reward systems (measures and appropriate incentives), organizational design, stakeholder management, human resources (HR) policies and procedures, executive coaching, change leadership training, team building and communication planning and execution

DUTCH: veranderingsmanagement

Checksum A mathematical value that is assigned to a file and used to “test” the file at a later date to verify that the data contained in the file has not been maliciously changed Scope Note: A cryptographic checksum is created by performing a complicated series of mathematical operations (known as a cryptographic algorithm) that translates the data in the file into a fixed string of digits called a hash value, which is then used as the checksum. Without knowing which cryptographic algorithm was used to create the hash value, it is highly unlikely that an unauthorized person would be able to change data without inadvertently changing the corresponding checksum. Cryptographic checksums are used in data transmission and data storage. Cryptographic checksums are also known as message authentication codes, integrity check-values, modification detection codes or message integrity codes.

DUTCH: controletotaal

1. COBIT 5: Formerly known as Control Objectives for Information and related Technology (COBIT); now used only as the acronym in its fifth iteration. A complete, internationally accepted framework for governing and managing enterprise information and technology (IT) that supports enterprise executives and management in their definition and achievement of business goals and related IT goals. COBIT describes five principles and seven enablers that support enterprises in the development, implementation, and continuous improvement and monitoring of good IT-related governance and management practices Scope Note: Earlier versions of COBIT focused on control objectives related to IT processes, management and control of IT processes and IT governance aspects. Adoption and use of the COBIT framework are supported by guidance from a growing family of supporting products. (See www.isaca.org/cobit for more information.)

2. COBIT 4.1 and earlier: Formally known as Control Objectives for Information and related Technology (COBIT). A complete, internationally accepted process framework for IT that supports business and IT executives and management in their definition and achievement of business goals and related IT goals by providing a comprehensive IT governance, management, control and assurance model. COBIT describes IT processes and associated control objectives, management guidelines (activities, accountabilities, responsibilities and performance metrics) and maturity models. COBIT supports enterprise management in the development, implementation, continuous improvement and monitoring of good IT-related practices. Scope Note: Adoption and use of the COBIT framework are supported by guidance for executives and management (Board Briefing on IT Governance, 2nd Edition), IT governance implementers (COBIT Quickstart, 2nd Edition; IT Governance Implementation Guide: Using COBIT and Val IT, 2nd Edition; and COBIT Control Practices: Guidance to Achieve Control Objectives for Successful IT Governance), and IT assurance and audit professionals (IT Assurance Guide Using COBIT). Guidance also exists to support its applicability for certain legislative and regulatory requirements (e.g., IT Control Objectives for Sarbanes-Oxley, IT Control Objectives for Basel II) and its relevance to information security (COBIT Security Baseline). COBIT is mapped to other frameworks and standards to illustrate complete coverage of the IT management life cycle and support its use in enterprises using multiple IT-related framework and standards.


CoCo Criteria of Control, published by the Canadian Institute of Chartered Accountants in 1995


Code of ethics A document designed to influence individual and organizational behavior of employees, by defining organizational values and the rules to be applied in certain situations. Scope Note: A code of ethics is adopted to assist those in the enterprise called upon to make decisions understand the difference between 'right' and 'wrong' and to apply this understanding to their decisions.

COBIT 5 perspective DUTCH: Gedragscode

Coevolving Originated as a biological term, refers to the way two or more ecologically interdependent species become intertwined over time Scope Note: As these species adapt to their environment they also adapt to one another. Today’s multi-business companies need to take their cue from biology to survive. They should assume that links among businesses are temporary and that the number of connections-not just their content-matters.

Rather than plan collaborative strategy from the top, as traditional companies do, corporate executives in coevolving companies should simply set the context and let collaboration (and competition) emerge from business units.

DUTCH: co-evolueren

DUTCH: Communicatiebesturingseenheid

Community strings Authenticate access to management information base (MIB) objects and function as embedded passwords Scope Note: Examples are:

Read-only (RO)-Gives read access to all objects in the MIB except the community strings, but does not allow write access

Read-write (RW)-Gives read and write access to all objects in the MIB, but does not allow access to the community strings

Read-write-all-Gives read and write access to all objects in the MIB, including the community strings (only valid for Catalyst 4000, 5000 and 6000 series switches).

Simple Network Management Protocol (SNMP) community strings are sent across the network in cleartext. The best way to protect an operating system (OS) software-based device from unauthorized SNMP management is to build a standard IP access list that includes the source address of the management station(s). Multiple access lists can be defined and tied to different community strings. If logging is enabled on the access list, then log messages are generated every time that the device is accessed from the management station. The log message records the source IP address of the packet.

DUTCH: tekenreeksen SNMP-community

Comparison program A program for the examination of data, using logical or conditional tests to determine or to identify similarities or differences DUTCH: vergelijkingsprogramma

Component A general term that is used to mean one part of something more complex Scope Note: For example, a computer system may be a component of an IT service, or an application may be a component of a release unit. Components are co-operating packages of executable software that make their services available through defined interfaces. Components used in developing systems may be commercial off-the-shelf software (COTS) or may be purposely built. However, the goal of component-based development is to ultimately use as many pre-developed, pretested components as possible.

Diverse routing The method of routing traffic through split cable facilities or duplicate cable facilities Scope Note: This can be accomplished with different and/or duplicate cable sheaths. If different cable sheaths are used, the cable may be in the same conduit and, therefore, subject to the same interruptions as the cable it is backing up. The communication service subscriber can duplicate the facilities by having alternate routes, although the entrance to and from the customer premises may be in the same conduit. The subscriber can obtain diverse routing and alternate routing from the local carrier, including dual entrance facilities. However, acquiring this type of access is time-consuming and costly. Most carriers provide facilities for alternate and diverse routing, although the majority of services are transmitted over terrestrial media. These cable facilities are usually located in the ground or basement.

Ground-based facilities are at great risk due to the aging infrastructures of cities. In addition, cable-based facilities usually share room with mechanical and electrical systems that can impose great risk due to human error and disastrous events.

Initialization vector (IV) collisions A major concern is the way that wired equivalent privacy (WEP) allocates the RC4 initialization vectors (IVs) used to create the keys that are used to drive a pseudo random number generator that is eventually used for encryption of the wireless data traffic. The IV in WEP is a 24-bit field--a small space that practically guarantees reuse, resulting in key reuse. The WEP standard also fails to specify how these IVs are assigned. Many wireless network cards reset these IVs to zero and then increment them by one for every use. If an attacker can capture two packets using the same IV (the same key if the key has not been changed), mechanisms can be used to determine portions of the original packets. This and other weaknesses result in key reuse, resulting in susceptibility to attacks to determine the keys used. These attacks require a large number of packets (5-6 million) to actually fully derive the WEP key, but on a large, busy network this can occur in a short time, perhaps in as quickly as 10 minutes (although, even some of the largest corporate networks will likely require much more time than this to gather enough packets). In WEP-protected wireless networks, many times multiple, or all, stations use the same shared key. This increases the chances of IV collisions greatly. The result of this is that the network becomes insecure if the WEP keys are not changed often. This furthers the need for a WEP key management protocol.

Nondisclosure agreement (NDA) A legal contract between at least two parties that outlines confidential materials that the parties wish to share with one another for certain purposes, but wish to restrict from generalized use; a contract through which the parties agree not to disclose information covered by the agreement Scope Note: Also called a confidential disclosure agreement (CDA), confidentiality agreement or secrecy agreement. An NDA creates a confidential relationship between the parties to protect any type of trade secret. As such, an NDA can protect non-public business information. In the case of certain governmental entities, the confidentiality of information other than trade secrets may be subject to applicable statutory requirements, and in some cases may be required to be revealed to an outside party requesting the information. Generally, the governmental entity will include a provision in the contract to allow the seller to review a request for information that the seller identifies as confidential and the seller may appeal such a decision requiring disclosure. NDAs are commonly signed when two companies or individuals are considering doing business together and need to understand the processes used in one another’s businesses solely for the purpose of evaluating the potential business relationship. NDAs can be "mutual," meaning that both parties are restricted in their use of the materials provided, or they can only restrict a single party.

First, if a standard set of test data and test results exist for a program, the output of a test run after program maintenance can be compared with the set of results that should be produced. Second, as programmers prepare test data and calculate the expected results, these results can be stored in a file and the output analyzer compares the actual results of a test run with the expected results. Third, the output analyzer can act as a query language; it accepts queries about whether certain relationships exist in the

file of output results and reports compliance or noncompliance.

Service Set Identifier (SSID) A 32-character unique identifier attached to the header of packets sent over a wireless local area network (WLAN) that acts as a password when a mobile device tries to connect to the base station subsystem (BSS). Scope Note: The SSID differentiates one WLAN from another so all access points and all devices attempting to connect to a specific WLAN must use the same SSID. A device will not be permitted to join the BSS unless it can provide the unique SSID. Because an SSID can be sniffed in plaintext from a packet, it does not supply any security to the network. An SSID is also referred to as a network name, because it is a name that identifies a wireless network.

DUTCH: Service set identifiers (SSIDs)

Service user The organization using the outsourced service.

Simple Object Access Protocol (SOAP) A platform-independent formatted protocol based on extensible markup language (XML) enabling applications to communicate with each other over the Internet Scope Note: Use of SOAP may provide a significant security risk to web application operations because use of SOAP piggybacks onto a web-based document object model and is transmitted via HyperText Transfer Protocol (HTTP) (port 80) to penetrate server firewalls, which are usually configured to accept port 80 and port 21 File Transfer Protocol (FTP) requests. Web-based document models define how objects on a web page are associated with each other and how they can be manipulated while being sent from a server to a client browser. SOAP typically relies on XML for presentation formatting and also adds appropriate HTTP-based headers to send it. SOAP forms the foundation layer of the web services stack, providing a basic messaging framework on which more abstract layers can build. There are several different types of messaging patterns in SOAP, but by far the most common is the Remote Procedure Call (RPC) pattern, in which one network node (the client) sends a request message to another node (the server), and the server immediately sends a response message to the client.

DUTCH: Simple Object Access Protocol (SOAP)

Wi-Fi Protected Access (WPA) A class of systems used to secure wireless (Wi-Fi) computer networks Scope Note: WPA was created in response to several serious weaknesses that researchers found in the previous system, Wired Equivalent Privacy (WEP). WPA implements the majority of the IEEE 802.11i standard, and was intended as an intermediate measure to take the place of WEP while 802.11i was prepared. WPA is designed to work with all wireless network interface cards, but not necessarily with first generation wireless access points. WPA2 implements the full standard, but will not work with some older network cards. Both provide good security with two significant issues. First, either WPA or WPA2 must be enabled and chosen in preference to WEP; WEP is usually presented as the first security choice in most installation instructions. Second, in the "personal" mode, the most likely choice for homes and small offices, a pass phrase is required that, for full security, must be longer than the typical six to eight character passwords users are taught to employ.

DUTCH: Wi-Fi Protected Access (WPA)

Wi-Fi protected access II (WPA2) Wireless security protocol that supports 802.11i encryption standards to provide greater security. This protocol uses Advanced Encryption Standards (AES) and Temporal Key Integrity Protocol (TKIP) for stronger encryption. DUTCH: Wi-Fi Protected Access II (WPA2)

DUTCH: Windows NT

Wired Equivalent Privacy (WEP) A scheme that is part of the IEEE 802.11 wireless networking standard to secure IEEE 802.11 wireless networks (also known as Wi-Fi networks) Scope Note: Because a wireless network broadcasts messages using radio, it is particularly susceptible to eavesdropping. WEP was intended to provide comparable confidentiality to a traditional wired network (in particular, it does not protect users of the network from each other), hence the name. Several serious weaknesses were identified by cryptanalysts, and WEP was superseded by Wi-Fi Protected Access (WPA) in 2003, and then by the full IEEE 802.11i standard (also known as WPA2) in 2004. Despite the weaknesses, WEP

provides a level of security that can deter casual snooping. DUTCH: Wired Equivalency Privacy (WEP)
