In the world of cybersecurity, ethical hacking has become a crucial practice to defend against rising cyber threats. Hackers who operate ethically, often referred to as white-hat hackers, are employed to probe systems, uncover weaknesses, and suggest defenses before criminals exploit them. But what gives these security experts their edge isn’t just the tools they use—it’s their knowledge of programming languages. Understanding programming is essential for ethical hackers to craft scripts, analyze vulnerabilities, reverse-engineer software, and even create custom attack payloads when off-the-shelf tools fall short. Ethical hacking is about…

The evolution of enterprise networks has reached a point where traditional WAN solutions no longer provide the agility, scalability, or centralized control that modern businesses require. In this landscape, vManage emerges as a critical component of the Software-Defined Wide Area Network (SD-WAN) architecture. It is designed to be the central nervous system for orchestrating and managing all devices and services across the SD-WAN fabric. vManage simplifies how networks are configured, monitored, and maintained. Rather than dealing with individual devices and manually applying policies, administrators can use vManage to deploy configurations,…

Point-to-Point Protocol over Ethernet, abbreviated as PPPoE, is a network protocol that enables users to connect to the internet through broadband connections such as DSL, fiber, and cable. By encapsulating PPP frames within Ethernet frames, PPPoE allows multiple hosts on a LAN to connect to a remote network using a single access point. This protocol has played a significant role in expanding broadband access by offering an effective way to provide authentication, usage tracking, and session management between users and their service providers. Although newer technologies like DHCP-based dynamic IP…
