Week 5 - Cryptography

-

In week 5, we got to learn more about cryptography. Cryptography is a secure way of hiding your data using code. It encrypts the required data to be hidden so that when a cyberattack happens and they gain unauthorized access, the plain text will be hidden with random words, letters, or shapes. Cryptography can hide all personal information by encrypting and can only be decrypted if the user or others have an encryption key. The key is used to decrypt the texts and give access to the user who is using the key.

Cryptography plays an essential part in cybersecurity and hardening your devices. When enabled, it takes your data and encrypts it to save it from cyberattacks. For example, if I were to put in my payment method, the numbers would come out as Iew81#24$dae!. With the encryption key, the user or others who gain the key can decrypt the text and give full access to the plain text. The encryption key is given to the owner of the data and can be shared with others as long as the user sends them the key so that they can gain access to the secure data.

Week 3 - Cloud Vulnerability Scans

In week 3, we continued to learn more about vulnerability scans, but this time, we continued learning by understanding cloud vulnerability. In recent years, we have relied on cloud services to help store our resources and data to continue to do the work required on different devices. With this resource and data being moved to a cloud service, some vulnerabilities could be hidden in the cloud provider. When doing a vulnerability scan on a cloud service, the scan will search for any security risk hidden in the cloud service. These security risks could be unauthorized access to the cloud, poor passwords, and further authentication that the provider hasn't set up. Our data needs to be safe on and off the cloud, so vulnerability scans are necessary when storing our essential data in the cloud. Ensuring there aren't any security risks in the cloud can ensure the data is locked and safe from cybercriminals.

Week 1 - Introduction

Hello! My name is Kyle Ross. Welcome to my newest blog. I'm majoring in information technology and getting closer to getting my degree. I'm currently in a course where we'll be learning about hardening computer systems and learning network risk management. System hardening and network risk management are setting up our systems to have complete security and protect us from cyberattacks and malicious codes created by cybercriminals to steal sensitive data from users. Cyberattacks are a serious cause, so taking the role of cybersecurity can help us stop these attacks and defend our information as much as possible. Each week, I'll write about what I have learned in the course and how they help protect us from these attacks. I have a history of using many different software and applications to protect myself, my family, and my friends from these attacks. Cybercriminals stop at nothing to get the information we need, which can be our social security number, financial informat...

Week 2 - Vulnerability Scan

In Week 2, we got to learn more about vulnerability scans. A vulnerability scan is a tool that can scan a system, network, or application. With this, the tool can identify weaknesses that could lead to potential cyberattacks. These vulnerabilities can be anything big or small. Whatever crack there is to the system, network, or application is an opening for cybercriminals to send malicious codes to the system, network, or application. That’s why it’s the vulnerability scan job to scan the entirety of the system, network, and application to find the vulnerability and give IT techs or others a chance to patch it up as soon as possible. An example of vulnerability scans is during a network scan; the tool finds a vulnerability and posts the results afterward. When the IT techs review the results, the scan will inform them that the network is open and not password protected. This allows the IT techs to create a password for the network and patch up this vulnerability to prevent unauthorized ...
