Life Cycle of Vulnerability Management

What is Vulnerability Management?

Vulnerability management is a program that addresses common cybersecurity weaknesses in an organization's software, hardware, and network. These vulnerabilities can be exploited by hackers to steal data or do a brute-force attack.

Therefore, vulnerability management helps to identify, close, and track these types of vulnerabilities and prioritize them in order of high risk to low risk.

Life Cycle of Vulnerability Management

Life Cycle of Vulnerability Management

1. Discover

This step involves the examination of operating systems, web services, hardware, web applications, and existing security patches to discover new vulnerabilities in the computer system.

2. Prioritize

After the discovery of vulnerabilities, these are prioritized based on their nature which is informational, low, medium, high, and critical. The critical vulnerabilities should be dealt with first in the order of precedence.

3. Assess

Now, assess all the vulnerabilities based on their severity. For example, low-risk vulnerabilities that affect one or two system does not require some level of urgency as high-risk vulnerability that affects all laptops and desktops.

4. Report

After Assessing each vulnerability, create a security plan for the computer system according to the risk and their level of importance. Document the steps that will be taken to remediate all known vulnerabilities.

5. Remediate

This is the most crucial step of the life cycle of vulnerability assessment. In this step, we take actions to fix the vulnerabilities like updating the hardware and software, applying security patches, updating configuration, etc.

6. Verify

This is the final step in which all the remediation measures taken are verified to eliminate the chances of errors. This step may take some time as verification should be done on all systems and ecosystems.

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
