Network Security

The rapid advancement of technology and the incorporation of Internet concepts into everyday life have resulted in a growing dependence on technology, which is driven by vulnerabilities and flaws in terms of security. Cybercriminals make use of the potential worth of information that is held on a variety of computer systems. This information can be categorized as physical assets such as product sources, business circumstances, and secret data reports.

DOS Attacks
Denial of Service attacks, often known as DoS attacks, are unlawful in the majority of countries and are typically carried out by instructing computers that have been compromised to simultaneously access the website that is being targeted. One of the most common types of denial-of-service assaults is called a Ping Flood Attack, which is sometimes referred to as an ICMP flood. In this type of attack, an overwhelming number of ping requests are sent to a target system, which floods the subject's network infrastructure and reduces the amount of bandwidth that is accessible to it. The purpose of these assaults is to interfere with the availability of the network and to open the door for exploits that are more sophisticated and potentially dangerous.


Ping Commands
One of the most common types of denial of service (DoS) attacks is known as a ping flood attack, which is also sometimes referred to as an ICMP flood attack. One of the characteristics of a ping flood attack is that it involves sending an excessive number of ping requests to the system that is the target of the assault. The network infrastructure of the subject is flooded with these requests, which are frequently initiated by a botnet. As a result, the subject's available bandwidth is rapidly declining. The ramifications manifest themselves in the form of network failures or significant slowdowns, which ultimately render services inaccessible. The primary purpose of this attack is to disrupt the availability of the network, which will ultimately pave the way for attacks that are more sophisticated and potentially problematic.

Vulnerability in Computer Systems
Our extreme dependence on technology has resulted from the integration of internet concepts into our daily lives and the constant and rapid advancement of technology. The availability of security vulnerabilities and weaknesses drives this dependence. Its goals cover the planet. Cybercriminals see the value of computer data before the typical internet user. Concrete benefits and unpredictable abilities are resources. Intangible assets include product sources, business conditions, and confidential data reports, whereas properties include operator details. These assets benefit the company financially, grow it, and increase its impact. In technology, cybercrime lawsuits have increased. This has shifted our focus to asset security. Computer security protects systems and data from unwanted access, manipulation, and damage.

Password Cracking
Document assembly password cracking recovers passwords from computer data. Attackers use brute force, rainbow table, and dictionary attacks to break into vulnerable systems. This puts individual and managerial accounts in danger of data misuse and computer system manipulation. Organizations can create password policies, avoid short and predictable passwords, and encrypt saved passwords to mitigate this issue. Companies can also check passwords against common and stolen lists. During login, setup, and reset, password screening programs check shortened passwords and username hashes.

Computer Viruses
Computer viruses are programs that spread by infecting files or system areas of a computer or network router's hard drive and making copies of itself. To protect your computer from viruses, install credible anti-virus software, regularly update it, and perform a virus scan before opening executable files. Exercise caution when downloading files or accessing links from member forums or chat rooms, and back up your data on a disc to avoid losing valuable work in case of a virus infection.

Scratch Experience

Scratch In the beginning of my experience with Scratch, which is a programming language, I encountered a great deal of difficulty with it. I was not familiar with the program because I had not used it since I was in middle school. This was the reason why I was uncertain about it. The reason I did not feel comfortable with it was because of this matter. Having said that, I discovered that the usage of Scratch made it simpler for students to personalize and construct their own narratives from scratch. In order to retain the knowledge that was required for utilizing the application, I watched tutorial videos and worked on improving my skills over the course of time. This allowed me to recall the information. One of the ways that I was able to remember the information was through the use of different strategies.  Based on what I have learned and what I was able to comprehend, the textbook provides a description of how the computer operates when receiving data and working with Scra...

About Me

My name is Abreya, and I was born and raised in the Upstate region of South Carolina. I am employed at a factory that manufactures medical devices as a CNC operator. Since I worked in computer communications while serving in the military, I have received some training in information technology. Since my job requires me to input data and work with coding for the equipment I am operating, I also work with information technology.     My goals for my professional life are to either secure a position with the Department of Homeland Security or work in the field of cybersecurity as a security analyst for a gaming firm. Because of my previous experience in the military and my desire to assist in the protection of the information of people that offer joy to others, such as Insomniac Games or Rockstar Games, I decided to go with these two specific companies.    I am hoping that by the end of this course, I will have a more in-depth understanding of computer systems and o...
