Domain 3 - Security Engineering Flashcards
Abstraction
Involves the removal of characteristics from an entity in order to easily represent its essential properties.
Access Control Matrix
A two-dimensional table that allows for individual subjects and objects to be related to each other.
Asymmetric Algorithms
One-way functions, that is, a process that is much simpler to go in one direction (forward) than to go in the other direction (backward or reverse engineering).
Address Space Layout Randomization (ASLR)
Involves randomly arranging the positions of key data areas of a program, including the base of the executable and the positions of the stack, heap, and libraries in a process’s memory address space.
Aggregation
Combining non-sensitive data from separate sources to create sensitive information.
Algorithm
A mathematical function that is used in the encryption and decryption processes.
Bell-La Padula Model
Explores the rules that would have to be in place if a subject is granted a certain level of clearance and a particular mode of access.
Brewer-Nash (The Chinese Wall) Model
This model focuses on preventing conflict of interest when a given subject has access to objects with sensitive information associated with two competing parties.
Cable Plant Management
The design, documentation, and management of the lowest layer of the OSI network model - the physical layer.
Certificate Authority (CA)
An entity trusted by one or more users as an authority in a network that issues, revokes, and manages digital certificates.
Ciphertext or Cryptogram
The altered form of a plaintext message, so as to be unreadable for anyone except the intended recipients.
Cloud Computing
A model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management.
Common Criteria
Provides a structured methodology for documenting security requirements, documenting and validating security capabilities, and promoting international cooperation in the area of IT security.
Community Cloud Infrastructure
Provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns.
Confusion
Provided by mixing (changing) the key values used during the repeated rounds of encryption. When the key is modified for each round, it provides added complexity that the attacker would encounter.
Control Objects for Information and Related Technology (COBIT)
Provides a set of generally accepted processes to assist in maximizing the benefits derived using information technology (IT) and developing appropriate IT governance.
Covert Channels
Communications mechanisms hidden from the access control and standard monitoring systems of an information system.
Cryptanalysis
The study of techniques for attempting to defeat cryptographic techniques and, more generally, information security services.
Cryptology
The science that deals with hidden, disguised, or encrypted communications. It embraces communications security and communications intelligence.
Cyber-Physical Systems (CPS)
Smart networked systems with embedded sensors, processors, and actuators that are designed to sense and interact with the physical world and support real-time, guaranteed performance in safety-critical applications.
Data Hiding
Maintains activities at different security levels to separate these levels from each other.
Data Warehouse
A repository for information collected from a variety of data sources.
Decoding
The reverse process from encoding - converting the encoded message back into its plaintext format.
Diffusion
Provided by mixing up the location of the plaintext throughout the ciphertext.
Digital Certificate
An electronic document that contains the name of an organization or individual, the business address, the digital signature of the certificate authority issuing the certificate, the certificate holder’s public key, a serial number, and the expiration date
Digital Rights Management (DRM)
A broad range of technologies that grant control and protection to content providers over their own digital media.
Digital Signatures
Provide authentication of a sender and integrity of a sender’s message.
Enterprise Security Architecture (ESA)
Focused on setting the long-term strategy for security services in the enterprise.
Firmware
The storage of programs or instructions in ROM.
