One-Time Pad: Cryptographic algorithm where plaintext is combined with a random key. It is the only existing mathematically unbreakable encryption. While it is unbreakable it is also very impractical. It has ONE use per pad; they should never be reused. Characters on the pad have to be truly random. The pads are kept secure.
Change Management: Often called change control, a formalized process on how we handle changes to our environments. If done right we will have full documentation, understanding and we communicate changes to appropriate parties. The change review board should be comprised of both IT and other operational units from the organization, we may consider impacts on IT, but we are there to serve the organization, they need to understand how it will impact them and raise concerns if they have any.
SDLC (Software Development Life Cycle): The SDLC is not really a methodology, but a description of the phases in the life cycle of software development. These phases are (in general), investigation, analysis, design, build, test, implement, maintenance and support (and disposal). Can have security built into each step of the process, for the exam it always does.
PII is the abbreviation for Personally Identifiable Information.
Static testing – Passively testing the code, it is not running. This is walkthroughs, syntax checking, and code reviews. Looks at the raw source code itself looking for evidence of known insecure practices, functions, libraries, or other characteristics having been used in the source code.
Source code escrow: The deposit of the source code of software with a third party escrow agent. Escrow is typically requested by a party licensing software (the licensee), to ensure maintenance of the software instead of abandonment or orphaning. The software source code is released to the licensee if the licensor files for bankruptcy or otherwise fails to maintain and update the software as promised in the software license agreement.
Scrum is a framework for managing software development. Scrum is designed for teams of approximately 10 individuals, and generally relies on two-week development cycles, called “sprints”, as well as short daily stand-up meetings. The three core roles in the Scrum framework. The product owner: Representing the product’s stakeholders, the voice of the customer, and is accountable for ensuring that the team delivers value to the business. Development team: Responsible for delivering the product at the end of each sprint (sprint goal). The team is made up of 3–9 individuals who do the actual work (analysis, design, develop, test, technical communication, document, etc.). Scrum master: Facilitates and accountable for removing impediments to the ability of the team to deliver the product goals and deliverables. Not a traditional team lead or project manager but acts as a buffer between the team and any distracting influences. The scrum master ensures that the Scrum framework is followed.
Source code escrow is the deposit of the source code of software with a third-party escrow agent. Escrow is typically requested by a party licensing software (the licensee), to ensure maintenance of the software instead of abandonment or orphaning.

The ClarkWilson integrity model provides a foundation for specifying and analyzing an integrity policy for a computing system. The model is primarily concerned with formalizing the notion of information integrity.
Clark-Wilson – Integrity: Separates end users from the backend data through ‘Well-formed transactions’ and ‘Separation of Duties’. The model uses Subject/Program/Object. We have discussed the Subject/Object relationship before, but this puts a program between the two. We don’t allow people access to our inventory when they buy from us. We give them a limited functionality interface they can access.
Cryptanalysis is the science of breaking encrypted communication. Cryptanalysis is used to breach cryptographic security systems and gain access to the contents of encrypted messages, even if the cryptographic key is unknown. It uses mathematical analysis of the cryptographic algorithm, as well as side-channel attacks that do not target weaknesses in the cryptographic algorithms themselves, but instead exploit weaknesses in their implementation and the devices that run them.
RAM (Random Access Memory) is volatile memory. It loses the memory content after a power loss(or within a few minutes). This can be memory sticks or embedded memory.
What does Iaaa stand for?
Identification Authentication Authorisation and
IAAA. Identification Authentication Authorisation and Accountability.
Polyinstantiation  (Alternative Facts) – Two (or more) instances of the same file depending on who accesses it. The real information may be available to subjects with Top Secret clearance, but different information will be available to staff with Secret or lower clearance.

What is the Bell LaPadula model * Star security property?
The BellLaPadula state machine model enforces confidentiality. The BellLaPadula model uses mandatory access control to enforce the DoD multilevel security policy. … Strong star * property—This property states that a subject cannot read/write to object of higher/lower sensitivity.
What is the difference between Bell LaPadula and Biba?
The BellLaPadula model focuses on data confidentiality and controlled access to classified information, in contrast to the Biba Integrity Model which describes rules for the protection of data integrity. In this formal model, the entities in an information system are divided into subjects and objects.
The Biba model sets out a hierarchical system which compares the integrity levels that are associated with files, processes, and people. … Invocation: The property whereby a subject at one integrity level is prohibited from invoking or calling up a subject at a higher level of integrity.
Polyinstantiation

Description

Polyinstantiation in computer science is the concept of type being instantiated into multiple independent instances. It may also indicate, such as in the case of database polyinstantiation, that two different instances have the same name

Polyinstantiation is the ability of a database to maintain multiple records with the same key. It is used to prevent inference attacks. It may also indicate, such as in the case of database polyinstantiation, that two different instances have the same name (identifier, primary key).

What is a sticky MAC address?
Sticky MAC is a port security feature that dynamically learns MAC addresses on an interface and retains the MAC information in case the Mobility Access Switch reboots. … Allowing the port to continuously learn MAC addresses is a security risk.
To enable sticky learning, enter the switchport port-security mac-address sticky command. When you enter this command, the interface converts all the dynamic secure MAC addresses, including those that were dynamically learned before sticky learning was enabled, to sticky secure MAC addresses
