Zeek, initially known as Bro, stands as the premier platform for monitoring network security. It is an adaptable, open-source solution driven by those dedicated to defense in the cybersecurity realm. With its origins tracing back to the 1990s, the project was initiated by Vern Paxson to gain insights into activities on university and national laboratory networks. In late 2018, to acknowledge its growth and ongoing advancements, the leadership team transitioned the name from Bro to Zeek. Unlike conventional security tools such as firewalls or intrusion prevention systems, Zeek operates passively by residing on a sensor, which can be a hardware, software, virtual, or cloud-based platform, that discreetly monitors network traffic. By analyzing the data it collects, Zeek generates concise, high-quality transaction logs, file contents, and customizable outputs that are well-suited for manual examination on storage devices or through more user-friendly applications like security information and event management (SIEM) systems. This unique approach allows for a deeper understanding of network activities without interfering with the traffic itself.

If you have concerns regarding your online safety, it's advisable to adopt strategies that can obscure your identity. One of the most prevalent methods utilized today involves concealing your IP address. Popular approaches include the use of proxy servers and various software applications. A Virtual Private Network (VPN) serves as an excellent resource for maintaining both your safety and anonymity. It establishes a secure and encrypted link between you and the website you are visiting. Upon connecting to a VPN server, all your online activity traverses through an encrypted tunnel, rendering it invisible to others until it emerges from the tunnel onto the public internet. Even when interacting with websites that employ HTTPS encryption, your personal information remains protected as it exits the tunnel. Furthermore, a VPN safeguards your data and helps you navigate the internet without leaving a trace of your online presence, ensuring a safer browsing experience overall.
