Title: Network Security: Protecting Against Phishing and Ransomware

Information and system security is one of the most important concerns for individuals and organizations today. With so much personal and professional data stored digitally, the consequences of a breach can be devastating—ranging from identity theft and financial loss to damaged reputations and interrupted operations. Even basic commands like ping, which are used for network troubleshooting, can be misused by attackers. For example, a ping flood or ping of death attack overwhelms a system with traffic, causing it to slow down or crash. This shows how tools meant for diagnosis can also be exploited as weapons.

Two of the most common threats today are phishing and ransomware. Phishing is a form of social engineering where attackers impersonate trusted sources to trick users into revealing login credentials or sensitive information. Systems are vulnerable because attackers exploit human error, using emails or text messages that look legitimate. When successful, phishing can lead to stolen financial accounts or compromised organizational networks. To defend against phishing, individuals and companies should (1) implement multi-factor authentication (MFA) and (2) train users to recognize suspicious messages.

Ransomware, on the other hand, is malware that encrypts files and demands payment for their release. These attacks often succeed when users download infected attachments or when systems are left unpatched. The damage can be catastrophic—lost data, downtime, and in some cases, permanent loss if no backups exist. To mitigate ransomware, organizations should (1) maintain regular offline backups and (2) practice strong patch management and endpoint protection.

Ultimately, cybersecurity comes down to prevention and awareness. By understanding how even simple tools like ping can be abused, and by taking steps to defend against phishing and ransomware, individuals and organizations can greatly reduce their risk in today’s digital landscape.

Welcome to Corey’s Cyber Journal Hello and welcome to Corey’s Cyber Journal! This blog is where I’ll be documenting my journey into the world of information technology and cybersecurity. Each week, I’ll share reflections from my coursework at The University of Arizona Global Campus, highlight hands-on activities like ping and traceroute exercises, and break down key concepts in ways that are both practical and approachable. My goal is to use this blog not only as a learning tool for myself but also as a resource for others who are interested in technology. Whether it’s exploring the basics of networking, digging into cybersecurity frameworks, or reflecting on how technology impacts everyday life, this blog will capture my growth and insights along the way. I invite you to follow along as I continue building my skills and preparing for a future career as a cybersecurity analyst. Thanks for visiting — let’s get started!

The fundamental elements of information technology form the basis of cybersecurity which protects people and organizations and governments from cyber threats.

Blog Post #7  Introduction Information technology has established cybersecurity as its most vital domain because it defends people and organizations and governments against escalating cyber threats. Data protection and system security have emerged as essential priorities because the world continues its digital transformation. The practice of cybersecurity extends beyond basic security tools because it depends on fundamental IT principles which include hardware systems and programming languages and database management and network infrastructure. The fundamental elements of information technology serve as the foundation for cybersecurity which this article demonstrates through its analysis of these essential components. Connection to IT Fundamentals The fundamental knowledge of IT serves as the foundation which cybersecurity professionals use to develop their work. System protection requires complete knowledge of computer operations and data processing methods and worldwide netwo...

  Blog Post #4 – Traveling Through a Network Title: Traveling Through a Network: Understanding Ping and Traceroute When we send information across the internet, data is broken into small units called packets. Each packet contains both the message and the addressing information that helps it reach its destination. These packets pass through multiple routers and servers, hopping across networks until they arrive at the target device. Tools like ping and traceroute make this process visible, showing us how data travels and where issues may occur. The ping command tests connectivity by sending packets to a destination and measuring how long it takes to receive a reply. It provides the roundtrip time (RTT) in milliseconds. In my tests, pinging a website hosted nearby returned much faster results than pinging one located across the country. This confirmed that geographical distance often increases latency. The traceroute command goes a step further by mapping each “hop” along t...
