The A+ certification serves as a starting point for individuals looking to pursue a career in IT support…

Understanding the ACT – History, Purpose, and Structure The Origins of the ACT The ACT, or American College Testing, was officially introduced in 1959. Its creator, Everett Franklin Lindquist, was a professor at the University of Iowa and an advocate for educational measurement. At the time, the SAT was already the dominant standardized test used by colleges and universities across the United States. Lindquist envisioned the ACT as a more academically grounded alternative. Instead of focusing heavily on abstract reasoning like the SAT, the ACT was designed to reflect the…

What is Social Engineering? Social engineering is a manipulation technique that exploits human psychology to gain confidential information, access systems, or perform unauthorized actions. Unlike conventional cyberattacks that target system vulnerabilities through code, malware, or brute force methods, social engineering targets the people who use those systems. It is based on the premise that people are the weakest link in the security chain. In essence, social engineering is the art of exploiting trust. It preys on natural human tendencies – like helpfulness, fear, urgency, or obedience to authority – to…

Introduction to Shell’s Arctic Ambitions Royal Dutch Shell, one of the world’s largest oil and gas companies, invested billions in Arctic exploration with the hope of tapping into vast untapped reserves of oil and natural gas. The Arctic, long considered the final frontier for oil exploration, held the allure of immense energy potential. Shell’s commitment to the region represented not only a business decision but also a statement of intent to lead in frontier energy development. However, the company’s eventual withdrawal in 2015 marked a turning point that reflected the…

Introduction In an increasingly digitized world, cybersecurity is no longer just a technical concern – it is a fundamental business priority. The growing sophistication of cyber threats, coupled with the massive volumes of sensitive data organizations handle, has led to the establishment of regulatory standards that mandate security awareness training for employees. This part explores the legal and regulatory frameworks driving this shift, explains their key training requirements, and outlines the foundational strategies for developing a compliant and effective cybersecurity education program. The Regulatory Imperative for Cybersecurity Training Cybersecurity breaches…

Understanding Next-Generation Firewalls (NGFWs) In today’s digital age, where businesses are increasingly relying on interconnected systems, securing a network is not just an option but a critical necessity. The advent of cloud-native environments, remote workforces, and digital transformation has significantly expanded the attack surface, making traditional firewalls insufficient to protect against evolving cyber threats. To address these challenges, Next-Generation Firewalls (NGFWs) have emerged as an essential security tool. The Rise of Next-Generation Firewalls Traditional firewalls were designed with a specific purpose: to protect networks by filtering traffic based on IP…

Introduction to IPSec: A Fundamental Overview In today’s connected world, securing communication over the internet is of paramount importance. While many are familiar with SSL (Secure Sockets Layer) and TLS (Transport Layer Security) as the primary protocols for securing web-based communication, there exists another critical protocol suite that focuses on securing entire network communication – IPSec (Internet Protocol Security). IPSec plays a vital role in ensuring the security of data and network traffic, especially in scenarios where secure connections between networks or secure remote access to private networks are required….

Introduction to High Availability in Palo Alto Firewalls Understanding High Availability in Network Security High Availability (HA) in network security refers to the ability of a system to remain continuously operational by eliminating single points of failure. In the context of Palo Alto Networks firewalls, HA is implemented by deploying two firewall appliances in a synchronized and cooperative configuration. This setup ensures that if one firewall encounters a hardware failure, software error, or loses connectivity, its counterpart can immediately take over without interrupting traffic flow or compromising security enforcement. The…
