What is fine-grained data?

What is fine-grained data?

Fine-grained parallelism means individual tasks are relatively small in terms of code size and execution time. The data is transferred among processors frequently in amounts of one or a few memory words. Coarse-grained is the opposite: data is communicated infrequently, after larger amounts of computation.

What is fine-grained and coarse grained access control?

The definitions start to hint at what the differences might be: fine-grained access control will work on smaller items whereas coarse-grained access control will work on larger items. Granularity can apply to the message being intercepted or the information being considered for access control.

What is the importance of the Describing fine-grained access control?

Fine-grained access control is important because it changes the rules of static authorization and enables secure sharing of many more sensitive information assets. However, this does require an effective and proven fine-grained authorizatio tool such as Axiomatics dynamic data masking solution.

What is fine-grained access control Elasticsearch?

Amazon Elasticsearch Service (Amazon ES) provides fine-grained access control, powered by the Open Distro for Elasticsearch security plugin. The security plugin adds Kibana authentication and access control at the cluster, index, document, and field levels that can help you secure your data.

What is fine-grained control?

Fine-grained access control is a method of controlling who can access certain data. Most often used in cloud computing where large numbers of data sources are stored together, fine-grained access control gives each item of data its own specified policy for access.

What is coarse grained access control?

coarse grained authorization. Granularity which literally means “level or scale of detail” and hence granularity in authorization means the level of details used to put on authorization rules for evaluating a decision to grant or deny the access.

What is coarse grained and fine grain?

In simple terms. Coarse-grained – larger components than fine-grained, large subcomponents. Simply wraps one or more fine-grained services together into a more coarse-grained operation. Fine-grained – smaller components of which the larger ones are composed, lowerlevel service.

What is fine-grained security?

What is fine-grain security? Fine-grained access control refers to the data security model where users of different permissions are given different sets of access rights to read, right, or edit data. These different application “views” all carry different access rights to the data.

What is AWS fine-grained access control?

Fine-grained access control offers additional ways of controlling access to your data on Amazon OpenSearch Service. Fine-grained access control offers the following benefits: Role-based access control. Security at the index, document, and field level. OpenSearch Dashboards multi-tenancy.

What is meant by fine grained access control?

What is a fine grain?

Definition of fine-grain 1 : producing images of low graininess so that considerable enlargement without undue coarseness is permitted —used of a photographic developer.

Why is fine grained access control is important?

Fine-grained access control allows data with different access requirements to coexist in the same storage or analytics environment. Developing a fine-grained access control schema is a challenging task that requires sophisticated expertise to implement effectively.

How does Guardium fine grained access control work?

In V10, Guardium provides its own powerful version of fine-grained access control. Rather than simply masking data in result sets, Guardium can dynamically change the query sent to the database based on who is issuing the query, where they are, when it is and what they are looking for.

How is Abe used to protect data confidentiality?

Although traditional encryption technology can be used to protect data confidentiality, it is relatively inefficient to serve the needs of flexible data sharing. Thus, the novel attribute-based encryption (ABE) [14] is applied to achieve fine-grained access control and preserve data confidentiality simultaneously.

How does attribute-based encryption enable data access control?

Especially, ciphertext-policy attribute-based encryption (CP-ABE) [15] enables the data owners to encrypt their data under specified access policy over a set of attributes, and the data recipients are allowed to decrypt the ciphertext only if their attributes satisfy the access policy associated with the ciphertext.
