Vulnerability Assessment: Definition, Types and Importance

What is Vulnerability Assessment?

The process of identifying security voids and weaknesses in an information system is known as vulnerability assessment. It checks and evaluates the suspected vulnerabilities in a system and provides information about its severity that is whether it is low, high, or critical, and suggests a way to mitigate them.

Threats like SQL injection, XSS injection, DoS attack, etc on a system can be prevented by vulnerability assessment.

Types of Vulnerability Assessment

Types of Vulnerability Assessment

1. Host Assessment

It includes vulnerability assessment of servers, workstations, and other network hosts. This assessment examines ports and services that the host is using.

2. Network Assessment

It includes vulnerability assessment of public and private networks on which the system is connected. This type of assessment can also detect vulnerabilities in wired and wireless networks.

3. Database Assessment

It includes vulnerability assessment of databases or big data systems. This assessment is for any misconfiguration in the database that can lead to attacks like SQL injection.

4. Application Assessment

It includes vulnerability assessment of web applications and their source code by automated scans.

Importance of Vulnerability Assessment

Through regular vulnerability assessment of networks, servers, and systems, an organization can minimize the chances of any potential data leak or attack on the system. It also gives the organization a better understanding of its assets, security flaws, and overall risk.

Conducting Polymers: Definition, Examples, Properties and Applications

Image
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

Raman Spectroscopy: Principle, Instrumentation and Applications

Image
What is Raman Spectroscopy? Raman spectroscopy was given by an Indian Physicist Sir C.V Raman , which is based on inelastic scattering of monochromatic light with the sample. The resulting light will have a different frequency than incident light due to this inelastic scattering.  This technique is widely used to analyze vibrational, rotational, and other low-frequency interactions in the molecule. This significantly helps in the elucidation of molecular structure, identifying functional groups, etc. Principle of Raman Spectroscopy Raman spectroscopy is based on the inelastic scattering of electromagnetic radiation with the molecule. We have two types of scattering that are elastic and inelastic scattering.  Elastic scattering obeys the Rayleigh law that states that there will be no loss of energy and momentum of the incidence radiation and scattered radiation. That's why this scattering is also known as Rayleigh scattering. Whereas, there will be some conditions (1 in million
