REFLECTIVE JOURNAL 1 Reflective Journal - Week 3 Akojie Oluwarotimi SEC 480 Wilmington University
REFLECTIVE JOURNAL 2 This week's focus was on cryptography, and it was an eye-opening experience as I delved into the world of secure data transmission and encryption techniques. Here are my reflections on this week's activities. I started the week by learning about number bases, such as binary, octal, hexadecimal, and base64. I realized that different number bases have unique applications in computer science and cybersecurity. Binary, for instance, is fundamental in representing data at the hardware level, while base64 is essential for encoding binary data into a human-readable format. Understanding number bases is crucial in cybersecurity, as data can be represented in various bases. It struck me that this knowledge would be invaluable in interpreting and analyzing data in the field. For example, when dealing with malware analysis or network traffic, knowing how to convert between bases can reveal hidden information. I had the opportunity to put my newfound knowledge to the test by decoding encoded text in different number bases. The challenges were engaging and required me to apply what I learned about binary, hexadecimal, and base64 conversions. Deciphering encoded messages was like solving puzzles, and it was gratifying to see the plaintext emerge. Through this week's activities, I reinforced my understanding of the fundamental concepts of cryptography. The idea that cryptography has been used for thousands of years, from ancient ciphers to modern encryption algorithms, is fascinating. It's clear that cryptography plays a crucial role in ensuring data confidentiality and integrity. As I progressed through the challenges, I couldn't help but think about the real-world applications of cryptography. From securing online communications and financial transactions to protecting sensitive data in organizations, the principles I learned are highly relevant in today's digital age. This week's lessons and challenges have inspired me to explore cryptography further. I see its importance not
REFLECTIVE JOURNAL 3 only in cybersecurity but also in my future career. Whether it's working on secure software development or data protection strategies, cryptography will be a valuable skill. In conclusion, Week 3 was an enlightening journey into the world of cryptography. It has broadened my knowledge, enhanced my problem-solving skills, and highlighted the significance of data security in the digital landscape. I look forward to applying what I've learned in both my academic and professional endeavors.
