There are two different types of covert channels, known as covert storage channels and covert timing channels, respectively.

What do you mean by covert channel?

A covert channel is any communication channel that can be exploited by a process to transfer information in a manner that violates the systems security policy. In short, covert channels transfer information using non-standard methods against the system design.

What is the purpose of a covert channel?

In computer security, a covert channel is a type of attack that creates a capability to transfer information objects between processes that are not supposed to be allowed to communicate by the computer security policy.

Is Steganography a covert channel?

Steganography is both a very old and very new field. The use of it as a covert channel allows a larger amount of data transfer at one time than most other covert channels.

What is a covert timing channel?

Definition(s): Covert channel in which one process signals information to another process by modulating its own use of system resources (e.g., central processing unit time) in such a way that this manipulation affects the real response time observed by the second process.

What is TCP covert?

A covert channel is described as: “any communication channel that can be exploited by a process to transfer information in a manner that violates the systems security policy.” [1] Essentially, it is a method of communication that is not part of an actual computer system design, but can be used to transfer information …

What is the problem of covert channel in VMM security?

However, there are chances for information leakage and possibilities of several covert channels for information flow between the virtual machines. Our work focuses on the experimental study of security threats in virtualization, especially due to covert channels and other forms of information leakage.

How are covert channels used by hackers?

A covert channel uses programs or communications paths in ways that were not intended. By using the covert channel, the Trojan can communicate or “phone home” undetected, and the hacker can send commands to the client component undetected.

Which of the following best describes a covert storage channel?

Covert communication is defined as the exchange of information/data using a covert channel. Covert channel can be implemented over almost all protocols and from the highest application layer to the lowest layer.

What is the principle behind cache based covert timing channel attacks?

A common type of covert channel attack uses shared caches. These cache-based attacks consists of the trojan creating a pattern of conflicts in the shared cache that can be interpreted by the spy process [5], [9], [6], [10], [11], [8], [7]. Typically, the spy process follows the so-called Prime+Probe technique.

Which Tcsec security rating addresses the use of covert channel analysis?

1.2 PURPOSE An important set of TCSEC requirements, which appears in classes B2 to A1,is that of covert channel analysis (CCA).

What does Tcsec stand for?

Trusted Computer System Evaluation Criteria (TCSEC) is a United States Government Department of Defense (DoD) standard that sets basic requirements for assessing the effectiveness of computer security controls built into a computer system.

Which is Division C in Tcsec?

TCSEC Division C is Discretionary Protection. “Discretionary” means Discretionary Access Control systems (DAC). Division C includes classes C1 (Discretionary Security Protection) and C2 (Controlled Access Protection). TCSEC Division B is Mandatory Protection.

What is Common Criteria compliance?

Common Criteria is a framework in which computer system users can specify their security functional requirements (SFRs) and security functional assurance requirements (SARs) using Protection Profiles (PPs). The CC is the driving force for the widest available mutual recognition of secure IT products across the globe.

Who uses Common Criteria?

Although the focus of the Common Criteria is evaluation, it presents a standard that should be of interest to those who develop security requirements. The Common Criteria (CC) were developed through a combined effort of six countries: the United States, Canada, France, Germany, the Netherlands, and the United Kingdom.

What does pp compliant mean?

From Wikipedia, the free encyclopedia. A Protection Profile (PP) is a document used as part of the certification process according to ISO/IEC 15408 and the Common Criteria (CC).

What is EAL certification?

An Evaluation Assurance Level (EAL) is a category ranking assigned to an IT product or system after a Common Criteria security evaluation. The level indicates to what extent the product or system was tested.

What qualifications do I need to be an EAL teacher?

How do I become an EAL teacher?

• post or professional graduate courses (PGCE – 1 year- full or part time),
• B Ed/BA with QTS (3 years),

• school based initial teacher training.

How do you qualify for EAL?

To qualify as an English as an additional language or dialect (EAL/D) teacher in a NSW government school you must be qualified as either a primary or secondary teacher and have approval to teach in a NSW government school.

What is EAL4 certification?

EAL4 is the highest level at which it is likely to be economically feasible to retrofit to an existing product line. Its aim is to demonstrate conformance of a product or system (referred to in evaluation-speak as a target of evaluation, or TOE) against its Security Target.
