At IETF 102: The Global Commission on the Stability of Cyberspace – Cyber diplomacy meets InfoSec and Technology

On Tuesday, 17 July, during IETF 102 in Montreal, the Global Commission on the Stability of Cyberspace (GCSC) will host a lunch panel on “Cyber Diplomacy Meets InfoSec and Technology.” During this session, the Commission wants to inform and engage with the IETF community on its work so far and the work that is in the pipeline.

The Global Commission on the Stability of Cyberspace is developing norms and policy initiatives that intend to counter the risk to the overall security and stability of cyberspace due to rise of offensive cyber-activities, and especially those by states.

Session Abstract

In this global environment we see conflict between states takes new forms, and cyber-activities are playing a leading role. There is an increasing risk of undermining the peaceful use of cyberspace and a growing for need norms and policies to enhance international security and stability.

The Global Commission on the Stability of Cyberspace, with commissioners from diverse backgrounds, sets out to develop proposals for norms and policies to enhance international security and stability and guide responsible state and non-state behavior in cyberspace.

During this lunch panel we want to engage with the IETF community to discuss the norms the commission Continue reading

Fetching Pcap Files and running Wireshark – Junos Pyez

As a part of some content development and revision on MPLS, I was trying to capture some MPLS Pcap Files from the Vmx Router. The problem was that every time I capture a file, I had to first scp or sftp into the device and then after successful import, I had to run Wireshark on it.

The Aim of the post is to fetch the pcap file and run Wireshark on it. Am not a decent programmer by any stretch of the imagination, anyone can see that from my code ? but the point that matters is that it works and you should give it a try too.

https://github.com/yukthr/auts/blob/master/junos_pyez/getfile_executewireshark.py– Is the file

 

 

When I run this program to fetch a non-existent Pcap file

 

And when I query for an existent file

10 hot SD-WAN startups to watch

The SD-WAN market is hot, with all of the usual networking suspects (Cisco, VMware, AT&T, Citrix, etc.) staking a claim. But make no mistake, this is a market sector that was built, defined, and refined by startups.A few early movers have already been taken off the table, snatched up by incumbents seeking to modernize their networking portfolios: Cisco acquired Viptela for $610 million; VMware bought VeloCloud for an estimated $449 million; NTT purchased Virtela for $525 million, and Riverbed, which was a leader in the precursor WAN optimization space, acquired Ocedo (price undisclosed) to help it manage its transition to a software-defined future.To read this article in full, please click here

The value-add of NSX Data Center Compared To Open Source Solutions For Cloud Native Apps

In our job as System engineers in the networking and security for Cloud native applications (CNA) space we get to work with many customers on their implementation of CNA platforms. The fun part of that is that we get to hear the “DevOps” drivers and needs of many enterprise customers. Developers using CNA platforms such as Kubernetes (k8s) and Pivotal Application Service (Formerly known as PCF) don’t always have security and networking first in mind; they are focused on speed and innovation. A developer doesn’t want to wait for the networking team to provision service (e.g. load balancing, switching, etc.), or for the security team to whitelist a new app capability. This is especially true in enterprises where “Change management” is manual and long process. On the other hand, when it comes to those same enterprises, there are regulations and security requirements that can slow down the innovation process. To strike a balance, networking and security platforms for CNA need to operate in as seamless a manner as possible to maximize speed and efficiency for both IT and developers. NSX Data Center is a platform built just for Continue reading

Copyright? Copywrong!

Copyright? Copywrong!

The drafting of the new EU Copyright Directive was never going to be an easy task. As has been seen over the years, policy discussions involving digital service providers and the intellectual property rights community are often polarizing, and middle ground can be difficult to find. However, the existing legal framework – which dates from 2001 - needed a refresh, in order to take account of the new online environment in which user-generated content is a key feature, while acknowledging the challenges that authors face and their need for fair remuneration.

Unfortunately, as is now so often the case in Brussels, the new law is being drafted with a small set of large Internet companies in mind. This blinkered approach to rule-making frequently results in unintended and negative consequences for other parts of the Internet ecosystem, and indeed for end users, many of whom are often unaware that such policies are being created.

Monitoring and Filtering User-Generated Content - A Flawed Approach

The draft copyright proposal has been undergoing EU Parliamentary and Council scrutiny since it was tabled by the European Commission in 2016, and it has been heavily criticised by civil society organisations, numerous industry associations, renowned academics and Continue reading

BrandPost: WaveLogic Ai: Laying the Foundation for the Adaptive Network

Today’s networking challenges Network operators know it all too well: Streaming video, cloud computing, the Internet of Things (IoT), and the evolution to 5G are putting massive pressure on today’s networks, requiring capacity increases by orders of magnitude and the ability to respond to even greater unpredictability in traffic patterns.The optical network sits at the heart of communications, interconnecting people, data centers, and an increasing number of devices across any distance, from across the street to across the ocean. Yet, for all the critical functions and agility they need to provide to meet today’s web-scale demands, most networks are weighed down with manual processes and hardware inflexibility.To read this article in full, please click here

Network Break 190: Aruba Joins SD-WAN Party; Cisco Buys Into WiFi Location Services

Take a Network Break! Aruba Networks rolls out a new SD-WAN platform plus a grand strategy for branch management, Cisco acquires July Systems for its wireless location services technology, and AT&T sells dozens of data centers for $1.1 billion.

But AT&T may take that cash and pour it into the acquisition of a digital ad exchange company, Deutsche Telecom announces big layoffs in its T-Systems unit, and Australian telco Telstra splits off its legacy infrastructure unit into a standalone business.

A Web Application Firewall (WAF) vendor lifts the curtain on why WAFs get bought but rarely used, HPE pledges $4 billion for edge computing, and Intel bids a terse goodbye to its CEO.
