Modern Day Attacks Against
Firewalls and Virtual Private Networks















Electronic technology is growing at a rapid rate; more devices are made mobile and wireless, but with those improvement and developments come flaws and malicious opportunities. Cyber attacks are on the rise and no system or device is immune. Many organizations employ multiple layers of firewalls but that doesn’t completely eliminate the threat. Attacks against firewalls and virtual private networks or VPNs are constantly being exploited with new methods everyday, but they are yet another obstacle that a cyber criminal must overcome.
First let’s discuss what a firewall is and what a firewall is capable of doing. Firewall applications are

These issues make it really important to understand how all rules and policies in the firewall work and how to apply them.
Another tool often used for secure reasons and also as a reliable method to share information remotely is called a Virtual Private Network or VPN. Henry describes A VPN as “a group of computers (or discrete networks) networked together over a public network—namely, the internet” (para 3, 2012).

A good VPN can provide many functions such as access anywhere worldwide without dedicated lines, data security, remote access to business resources and better employee production. For these VPNs to perform these functions properly they are required to provide reliability by ensuring that the network does not break down before reaching its max capacity, scalability to ensure the ability to expand as business grows, and of…
