September 2017 Podcast
Rachel Kartch

In this podcast, the latest in a series on best practices for network security, Rachel Kartch explores best practices for network border protection at the Internet router and firewall.

“Frankly, in my experience I find that there are often errors of either doing too much or doing too little at different places in the border. It seems like an important topic for us to cover because it is a critical part of anybody’s defense.”

Abstract

When it comes to network traffic, it’s important to establish a filtering process that identifies and blocks potential cyberattacks, such as worms spreading ransomware and intruders exploiting vulnerabilities, while permitting the flow of legitimate traffic. In this podcast, the latest in a series on best practices for network security, Rachel Kartch explores best practices for network border protection at the Internet router and firewall. It is important to note that these recommendations are geared toward large organizations and government agencies and would not likely be appropriate for a home network or very small business network.
