ACCEPTABLE LEVEL OF RISK  look up translate image
A judicious and carefully considered assessment by the appropriate authority that a business, computing activity or network meets the minimum requirements of applicable security directives. The assessment should take into account the value of assets; threats and vulnerabilities; countermeasures; and operational requirements.
ACCEPTABLE USE POLICY  look up translate image
De facto nomenclature for documented standards and/or guidance on usage of information systems and networked assets.
ACCESS  look up translate image
The ability to enter a secured area. The process of interacting with an access control system and being permitted access

A set of procedures performed by hardware, software and administrators to monitor access, identify users requesting access, record access attempts, and grant or deny access.
ACCESS TOKEN  look up translate image
In Windows, an internal security card that is generated when users log on. It contains the security IDs (SIDs) for the user and all the groups to which the user belongs. A copy of the access token is assigned to every process launched by the user.
ACCOUNTABILITY  look up translate image
The principle that individuals using a facility or a computer system must be identifiable. With accountability, violations or attempted violations of system security can be traced to individuals who can then be held responsible.
ACCREDITATION  look up translate image
A program whereby a laboratory demonstrates that it is operating under accepted standards to ensure quality assurance. Passing ISO 9000 is called Accredited Certification
ACQUISITION  look up translate image
The stage in a computer forensic investigation where data is collected. Most often, this is done by making bit-by-bit copies of the hard disk/media.
ACQUISITION OF DIGITAL EVIDENCE  look up translate image
Begins when information or physical items are collected or stored for examination purposes. The term "evidence" implies that the collector of evidence is recognized by the courts. The process of collecting is also assumed to be a legal process and appropriate for rules of evidence in that locality. A data object or physical item only becomes evidence when so deemed by a law enforcement official or designee.
ACTIVE DATA  look up translate image
Data on a computer that is not deleted and is visible to the Operating System under normal use.
ADDRESS  look up translate image
The term address is used in several ways. An Internet address or IP address is a unique computer (host) location on the Internet. A Web page address is expressed as the defining directory path to the file on a particular server. A Web page address is also called a Uniform Resource Locator, or URL. An e-mail address is the location of an e-mail user (expressed by the user's e-mail name followed by an "at" sign (@) followed by the user's server domain name.

ALLOCATED DATA  look up translate image
Data on a drive that has not been deleted or written over.
ALLOCATION UNIT / CLUSTER  look up translate image
The smallest unit of storage (number of sectors) that can be allocated by the Operating System to store data. The size of an allocation unit varies depending on the Operating System and size of the disk.
AMBIENT DATA  look up translate image
Ambient data is information that lies in areas not generally accessible to the user. This data lies in file slack, unallocated clusters, virtual memory files and other areas not allocated to active files. This is a forensic term that describes, in general terms, data stored in non-traditional computer storage areas and formats. The term was coined in 1996 to help students understand computer-evidence-processing techniques that deal with ev-idence not stored in standard computer files, formats, and...(more)
ANALYSIS  look up translate image
To look at the results of an examination for its significance and probative value to the case.
ANODE  look up translate image
A key part of the Linux file system that contains UIDs, GIDs, modification, access, creation times, and file locations.
ANOMALY DETECTION  look up translate image
A label for the class of intrusion-detection tactics that seek to identify potential intrusion attempts by virtue of their being (presumably) sufficiently deviant (anomalous) in comparison with expected or authorized activities. Phrased another way, anomaly detection begins with a positive model of expected system operations and flags potential intrusions on the basis of their deviation (as particular events or actions) from this presumed norm.
ANONYMOUS FTP  look up translate image
Allows visitors to upload and/or download predetermined files from designated directories without usernames or passwords. For example, distribute your latest software package by allowing visitors to download it through anonymous FTP. This is different than a regular FTP account

ARCHIVE  look up translate image
After processing discovery materials, an archive is created for each case.
ARCHIVE FILE  look up translate image
A file that contains other files (usually compressed files). It is used to store files that are not used often or files that have been stored on a server or other location in this form to save space.
ATTACHMENT  look up translate image
A file carried with an e-mail.
AUDIT  look up translate image
Examination and/or assessment of actions and records to ensure compliance with policies and operational procedures. If problems are found, recommendations are made to change policies or procedures. The independent examination of records to access their veracity and completeness.
AUDIT TRAIL  look up translate image
In computer security systems, a chronological record of when users log-in, how long they are engaged in various activities, what they were doing, and whether any actual or attempted security violations occurred. An automated or manual set of chronological records of system activities that may enable the reconstruction and examination of a sequence of events and/or changes in an event.
AUP  look up translate image

AUTHENTICATION  look up translate image
The process of establishing the legitimacy of a user (or node) before allowing access to requested information. An example is for the user to enter a name or account number (identification) and password (authentication).
AUTHORIZATION  look up translate image

BASELINE  look up translate image
An established standard for measurement or comparison.
BIG ENDIAN  look up translate image
In a big-endian system, the most significant value in the sequence is stored at the lowest storage address (i.e., first). Many mainframe computers, particularly IBM mainframes, use a big-endian architecture. Most modern computers, including PCs, use the little-endian system. The terms big endian and little endian are derived from the Lilliputians of Gulliver's Travels, whose major political issue was whether soft-boiled eggs should be opened on the big side or the little side.
BIOS  look up translate image
The Basic Input Output System of a PC. This is usually a number of machine code routines that are stored in ROM and available for execution at boot time. The "boot strap loader" is contained in ROM and is the first code to execute when the computer is turned on. The BIOS contains commands for reading the physical disks sector by sector.

BOOKMARK  look up translate image
A marker or address that identifies a specific place or location for subsequent retrieval.
BOOT  look up translate image
