Classification of Data in Cybersecurity

What is Data?

Data is the raw/discrete information like numbers, binary data, metadata, etc. Different types of data use classified ascending to their type, sensitivity and it's value. Following are the various types of classification of data.

Classification of Data

Classification of Data

1. Based on sensitivity levels

(a) High-sensitive data

This includes data that is highly sensitive or important and its leak would have a catastrophic result. For eg, Financial records, intellectual property, and authentication data. This data need to be encrypted while saving on servers and only some administrators should be given permission to access it.

(b) Medium-sensitive data

This includes data that is moderately sensitive and its leak would not have an extreme or catastrophic result. For eg, email and documents have no confidential data. This data can be encrypted with passwords but generally, it is not necessary and only those documents which contain some sensitive information need to be encrypted.

(c) Low-sensitive data

This includes data that is openly available in the public domain and does not contain any confidential information. For eg, Articles, photos, and videos on a public website.

2. Based on content, context, and user solution

(a) Content-based classification

This type of data contains only content like files, documents, articles, etc. This data is classified based on the nature of the content.

(b) Context-based classification

This type of data includes files based on metadata like the application that created the file, the person who created the document, and the location in which files were authored or modified.

(c) User-based classification

This type of data is classified by the user itself or any other knowledgeable person.

Conducting Polymers: Definition, Examples, Properties and Applications

What are Conducting Polymers? As the name suggests organic polymers that conduct electricity are known as conducting polymers. They are also known as intrinsically conducting polymers (ICPs) and they have alternating single and double bonds along the polymer backbone (conjugated bonds) or that are composed of aromatic rings such as Phenylene, naphthalene, anthracene, pyrrole, and thiophene which are connected through carbon-carbon single bonds. Examples: Polyacetylene, Polypyrrole, Polyaniline, etc What is the reason behind conducting nature of these polymers? Conducting polymers comes in two forms that are doped conducting polymers and non-doped conducting polymers. The conductivity of non-doped conjugated polymers is due to the existence of a conductivity band similar to a metal. In a conjugated polymer, three of the four valence electrons form strong sigma bonds through sp² hybridization where electrons are strongly localized. The remaining unpaired electron of each carbon atom re

Crime Scene: Definition, Types and Characteristics

What is a Crime Scene ? A place where the crime is committed or where the maximum physical evidence related to crime is found is known as a crime scene. A crime scene is a starting point of the investigation which provides information about the suspect and the victim. This helps to reconstruct the crime and fast resolution of the case. It is noted that the crime scene is not limited to a single place but may extend to a wider area depending upon the nature of the crime committed. For example, In a murder case where murder is done at one place and the body is disposed on another place. In this case, we have two crime scenes that give information about the crime. Types of Crime Scene Based on evidence found on the crime scene: 1. Primary Crime Scene The crime scene where the actual crime occurred or where more usable pieces of evidence were found is known as the primary crime scene. For example, A murder scene, theft, assault, etc. 2. Secondary Crime Scene The crime scene which is some

Documentation of the Crime Scene: Step by Step

Image
What is documentation of the crime scene and Why it is done? After securing the crime scene, the next most important step is documentation of the crime scene because documentation permanently records the crime scene and its physical evidence. Documentation should be done without any wastage of time as the scene and its evidence may get altered over time. The documentation should be done innovatively and the originality of the crime scene should be maintained and documentation should not have pauses or breaks, it should remain constant till the whole crime scene is documented. There are four main tasks of documentation that is note-making, photography, videography , and sketching . It should be noted that all four tasks are necessary and none is a substitute for another. For example, notes are not substitutes for photography, video is not a substitute for sketching, etc. Following are the sequence for crime scene documentation: 1. Note making Documentation of crime scene in the f
