Worth Reading: Firewall Policies

Every firewall policy starts simple and with the best of intentions, only to grow and change until it no longer resembles its former self. Firewall management is so vital that it is the first requirement in the Payment Card Industry (PCI) Data Security Standard. Even if you are not required to be audited against PCI or similar standards, we can borrow some aspects to increase the security of any network. —Jamie Gillespie @APNIC

Is the world ready for instant IoT?

The Internet of Things (IoT) is everywhere these days, a status cemented by IoT technology’s star turn at the 2018 Consumer Electronics Show in Las Vegas earlier this month.Notably, that’s true even as many enterprises struggle to develop workable IoT devices and applications as they deal with multiple incompatible platforms, operating systems and standards. Making things even harder, many IoT systems need to work in harsh, remote, space-constrained and low-power environments. Those are just some of the reasons why IoT development often takes six months to a year and costs hundreds of thousands of dollars—especially for global markets.To read this article in full, please click here

The Process of Developing and Submitting an IETF Internet Draft: My Story

I had a week off, and being a security domain researcher, I started working on automating security rules in network security components. The goal was to read the existing security rules of the IPv4 protocol and deploy parallel security rules for the IPv6 protocol in the same security component for the newly configured protocol in a network. For this purpose, I started to develop an automation service. The service was intended to use the IPv4 address in a DNS query to resolve the corresponding IPv6 address. The next intended step was to add these same rules in the network security component for the newly resolved IPv6 address. This was when I came to know that the existing DNS protocol does not provide IPv4 to IPv6 resolution and vice versa.

While trying to figure out a solution to this problem, the Internet Society Pakistan Islamabad Chapter announced to carry-out a local IETF-Outreach Program managed by Internet Society Asia-Pacific Bureau. As part of the program, a seminar was conducted that introduced the history of IETF and outlined the process of the Internet standards-making process, including how we could get involved in this process. The most appealing part of the programme was the Continue reading

Large drop in traffic from the Democratic Republic of Congo

It is not uncommon for countries around the world to interrupt Internet access for political reasons or because of social unrest. We've seen this many times in the past (e.g. Gabon, Syria, Togo).

Today, it appears that Internet access in the Democratic Republic of Congo has been greatly curtailed. The BBC reports that Internet access in the capital, Kinshasa was cut on Saturday and iAfrikan reports that the cut is because of anti-Kabila protests.

Our monitoring of traffic from the Democratic Republic of Congo shows a distinct drop off starting around midnight UTC on January 21, 2018. Traffic is down to about 1/3 of its usual level.

We'll update this blog once we have more information about traffic levels.

Synchronize Network Management Parameters across Network Devices

While I have stock homework assignments prepared for every module of the Building Network Automation Solutions online course I always encourage the students to pick a challenge from their production network and solve it during the course.

Pavel Rovnov decided to focus on consistency of network management parameters (NTP, SNMP, SSH and syslog configuration) across Extreme and Cumulus switches, Fortinet firewalls and several distributions of Linux.
