In the world of cybersecurity, securing network communications and ensuring trusted authentication are paramount. One of the most widely used and trusted methods for achieving this is through the Kerberos authentication protocol. Originally developed by the Massachusetts Institute of Technology (MIT) in the 1980s, Kerberos was created as part of MIT’s Project Athena. The protocol was designed to address the security challenges that come with open and untrusted networks, particularly in environments where sensitive data is exchanged, and strong authentication is necessary. Kerberos gets its name from the three-headed dog…

Hacking is a term that has been a part of our world for decades. It refers to the process of gaining unauthorized access to systems, networks, or devices. While hacking is typically associated with malicious activity, there is also a positive side to hacking: ethical hacking. Ethical hackers, often referred to as white hat hackers, use their skills to find vulnerabilities in systems and help organizations secure their digital infrastructures before malicious hackers can exploit those weaknesses. The digital age has introduced an unprecedented level of interconnectivity, which has brought…

Steganography is an ancient technique that revolves around the concept of hiding sensitive information within an ordinary, non-suspicious file or message. The term steganography comes from the Greek words steganos, meaning “covered” or “hidden,” and graphy, meaning “to write”—essentially “hidden writing.” Unlike cryptography, which makes data unintelligible to unauthorized users, steganography’s main purpose is to hide the very existence of the data itself. In cybersecurity, this technique is used to ensure that secret information goes unnoticed and avoids detection by unauthorized individuals or attackers. In the context of modern technology,…
