week 7 reyna Cybersecurity Threat Hunting: Proactive Defense in Action

 Cybersecurity Threat Hunting: Proactive Defense in Action

Cybersecurity threat hunting is a proactive process that allows organizations to stay ahead of sophisticated cyber threats by actively searching for indicators of compromise (IOCs) within their networks and endpoints. Rather than waiting for alerts from security tools, threat hunters operate under the assumption that adversaries may already be inside the system. They use tactics such as behavioral analysis, hypothesis-driven investigations, and the MITRE ATT&CK framework to identify suspicious activity that may otherwise go undetected. According to Chapter 13 of the CompTIA CySA+ Cybersecurity Analyst Certification Guide, this process relies heavily on understanding the environment, defining normal behavior, and identifying anomalies.

An often overlooked yet vital part of threat hunting is envisioning how attackers might compromise organizational assets. This mindset helps build better threat models and detection rules by mimicking potential attack paths. Organizations must think like adversaries whether considering phishing campaigns, privilege escalation, or lateral movement to effectively defend against them. Though tools and techniques may differ across industries, the foundational tactics of threat hunting such as establishing a baseline, using threat intelligence, and continuously refining detection capabilities to remain consistent. Ultimately, threat hunting enhances an organization’s resilience by turning security from reactive to proactive.

week 1 reyna

My name is Johnny Reyna, and I’m excited to step into the IT blogging world as I continue my journey toward a degree in Information Technology. This space will be my platform to reflect on what I’m learning, share insights, and hopefully spark meaningful conversations with others passionate about the world of cybersecurity and networking. This term, I’m diving into the topic of System Hardening and Network Risk Management —a critical area in today’s digital landscape. With cyber threats becoming more sophisticated and widespread, understanding how to reduce vulnerabilities and protect systems is more important than ever. Although I’m still growing my experience in this area, I understand that system hardening involves securing systems by reducing their attack surface—removing unnecessary software, disabling unneeded services, applying patches, and configuring system settings properly. It’s all about making it harder for attackers to exploit weaknesses. On the other hand, network risk ...

week 5 Reyna Securing the Modern Ecosystem

  🔒 Securing the Modern Ecosystem: Software and Hardware Assurance Across Platforms As technology evolves, so do the threats that target our systems. Whether it’s a smartphone app, an IoT thermostat, or a complex embedded system in an industrial controller, the need for robust software and hardware security practices is more critical than ever. This week, I explored how software assurance best practices are applied across a range of platforms—including mobile devices, client/server systems, embedded devices, and firmware —and how hardware-level protections are becoming equally important in building resilient systems. Here are the key insights: 🧩 Software Assurance Across Diverse Platforms Today’s digital ecosystem runs on a wide mix of software environments. From mobile apps to web services and IoT programs, software assurance must be adaptable, yet consistent. A few best practices that span all these environments include: Code Signing : Ensures the integrity and auth...

week 6 Reyna Proactive Monitoring Through Data Analysis

                                    Proactive Monitoring Through Data Analysis As cybersecurity threats continue to evolve in sophistication and stealth, organizations face an urgent need to detect and respond to breaches faster than ever before. Traditional security monitoring methods although foundational are no longer sufficient on their own. This week’s exploration of Chapters 11 and 12 from CompTIA CySA+ Cybersecurity Analyst Certification All-In-One Guide highlights a critical shift in how modern defenders must think about monitoring: from reactive to proactive. One of the key takeaways is the growing role of data analysis in security monitoring . Security teams now rely heavily on Security Information and Event Management (SIEM) tools, endpoint detection and response (EDR), and machine learning-based analytics to parse through enormous volumes of log and network data. These tools do more ...
