Cybersecurity and it's Types

What is Cybersecurity?

Cybersecurity is the practice of protecting computers, software, data, etc from hackers and malicious attackers. Cybersecurity is also known as Information security as all the information stored in computer and servers need to be secured. 

Cybersecurity is essential because nowadays every organization like government, corporate, financial, medical, etc uses the Internet and computers. So, the chances of a security breach are high in them. Cybersecurity can be divided into the following categories:

1. Network security

Network security

Network security is the process of protecting computers, mobile, etc connected to a network. For example, Network security is essential because nowadays every computer device or IoT device is connected to the internet or other Public/Private network. Hackers can use this network to penetrate these devices and compromise their security.

2. Application Security

Application security is the process of protecting the computer applications like web browsers, mail, etc from malicious attackers. It is necessary to secure these applications because the majority of the personal data is stored in these applications.

Application Security

Application security can be implemented by securing the apps with passwords, using two-factor authentication, downloading the apps from trusted websites, etc.

3. Information security

Information security

Information security is the practice of securing the informational data like Name, Date of birth, location, etc of the user from misuse by any unauthorized person. Information security is implemented on applications, web servers, storage devices, etc. Information security helps an organization from data leaks or the spreading of disinformation.

4. Cloud security

Cloud security

Cloud security is the practice of securing the cloud server and its data from access by any unauthorized person. It is necessary because all the data of the user who uses apps is stored on the cloud platform. Any data leak will lead to the loss of the personal information of the user. Also, the attacker can initiate a DoS (Denial f service) attack against the cloud server to suspend the services.

5. IoT security

IoT security

IoT security is the practice of securing IoT (Internet of things) devices from any malicious attack. IoT devices include smart Tv, watch, refrigerators, etc that are connected to their respective mobile app through a wi-fi network. So, it is necessary to protect them as they also contain important data of the user.

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

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
