Tech Topic Connection | Network Security

  Network security functions as an essential IT element which protects data as it moves between computer networks. Digital communication growth requires network protection against unauthorized access and attacks and data breaches to become an essential priority. The paper investigates how network security relates to fundamental IT concepts including hardware and software and programming and databases and network architecture.Network security functions to defend IT systems by protecting data through confidentiality integrity and availability which represent fundamental cybersecurity principles. These principles remain essential for protecting data throughout its transmission and storage processes. Bayuk et al. (2012) stress that strong security policies form an essential foundation to defend IT infrastructure from cyber threats which threaten operational continuity and data confidentiality. Network security has developed through the progressive stages of computer science. The early computing era featured isolated systems which did not face significant security challenges. The growth of internet vulnerabilities led to the creation of security technologies which include firewalls encryption and intrusion detection systems. The security of modern networks depends on having a solid grasp of computer architecture and cryptographic algorithms according to Grimes (2017). Network security depends on hardware devices including routers switches and firewalls for its operation.  Network traffic passes through these devices which function to monitor and control data flow while blocking unauthorized access and detecting security threats. Security effectiveness demands expertise in understanding network components and their configuration methods for maximum protection. Network security depends on programming languages to function effectively. Security tasks are automated through Python and C scripts which also  monitor network activity and develop firewall and intrusion detection system defense mechanisms. Network security depends on application software to  protect against attacker exploitation of common program vulnerabilities.

Network Security | Social Engineering & HTTPS

  Modern interconnected operations create a situation where information system security stands as an essential fundamental component. The online storage and transmission of sensitive data expose individuals and organizations to rising cyberattack threats. Information systems require secure confidentiality and integrity and availability protections because they prevent financial losses and reputational damage and privacy violations. The National Institute of Standards and Technology (NIST) defines information security as the set of processes which protect digital data against unauthorized access or modification (NIST, 2020). The attacks which take advantage of human behavior along with standard tools are equally dangerous as those that exploit technical vulnerabilities. The "ping" command serves as a primary illustration of misuse. The ping command serves network diagnostic functions, but attackers use it to execute Ping Flood and Denial-of-Service (DoS) attacks. Attackers lau...

Programming Languages | Scratch

Through the use of Scratch, I was able to get my first real exposure to programming and gain some important understandings of the process and its fundamentals. Scratch is a graphical user interface programming language which uses blocks of codes that can be dragged and connected instead of typing in codes. My project was a simple one, where two cats would converse with the user and provide responses and move around. This exercise helped me grasp the fundamental of programming like loops, conditionals and events. The feedback was almost instant which made testing and debugging easier and thus I got a clearer picture of how the code is executed and how it is linked within the program.   The major thing that I was able to learn from this experience was that every process should be divided into parts or steps in order to make the solution of a problem easier. For instance, I broke down my scratch program into components such as movement, looping and questions. This is very essential in...

Documenting a Day | Application Software

  All types of application software were developed for certain purposes in the field of data processing and presentation.   The main purpose of Word processing software, including Microsoft Word and Google Docs, is to develop, modify and arrange text documents. These applications help the user to organize the written content in a systematic way and also offer the user the ability to make the content more presentable to readers through formatting. Spreadsheet applications like Microsoft Excel and Google Sheets are used in organizing numerical data, performing calculations and presenting the data in forms of charts or graphs to represent the information in a better way. Presentation software including Microsoft PowerPoint and Google Slides assists the user in developing multimedia slideshows that are often used in educational or professional settings.   Database applications like Microsoft Access and MySQL are used in the collection, storage, and retrieval of structured dat...
