DNS Spoofing: Altering DNS Records to Redirect Traffic to Malicious Sites
Introduction to DNS Spoofing The Domain Name System (DNS) serves as the internet’s phonebook, translating human-friendly domain names into numerical IP addresses that computers use to identify each other on the network. When you type a website address into your browser, the DNS system translates that address into a corresponding IP address, allowing your device…

Multi-Factor Authentication (MFA): Enhancing Security in an Era of Rising Cyber Threats
Introduction to Multi-Factor Authentication (MFA) Multi-Factor Authentication (MFA) is a security enhancement that requires users to provide two or more verification factors to gain access to a resource such as an application, online account, or VPN. Rather than just asking for a username and password, MFA requires additional credentials, further fortifying the authentication process. This…
