Welcome to Technology Short Take #82! This issue is a bit behind schedule; I’ve been pretty heads-down on some projects. That work will come to fruition in a couple weeks, so I should be able to come up for some air soon. In the meantime, here’s a few links and articles for your reading pleasure.

I already wrote about Control Plane Protection in one of my previous posts focused on Cisco device configuration. Here we will make the same thing on Juniper device, I was using Juniper SRX300 and Juniper SRX1500 devices in my lab. CoPP ?? Control Plane Protection (CoPP) is a method of protecting processor unit, running services on your network device, against excessive flooding. Excessive flooding of traffic aimed towards your router/firewall processor, being that valid or malicious, is always undesirable and can also be dangerous. A network device, which starts the receive more control traffic that his processor can process, will

Despite the movement to cloud, data centers will still be around for the foreseeable future.
In a traditional TLS handshake, the client authenticates the server, and the server doesn’t know too much about the client. However, starting now, Cloudflare is offering enterprise customers TLS with client authentication, meaning that the server additionally authenticates that the client connecting to it is authorized to connect.
TLS Client Authentication is useful in cases where a server is keeping track of hundreds of thousands or millions of clients, as in IoT, or in a mobile app with millions of installs exchanging secure information. For example, an IoT company can issue a unique client certificate per device, and then limit connections to their IoT infrastructure to only their devices by blocking connections where the client doesn’t present a certificate signed by the company’s certificate authority.
Or in the case of a mobile banking app, where the bank wants to ensure customers’ secure financial data doesn’t get stolen by bots spoofing their mobile app, they can issue a unique certificate to every app install and in the TLS handshake validate requests are coming from their mobile app. Client authentication is also useful for VPNs, enterprise networks or staging sites, where corporations and developers need to lock down connections to only laptops Continue reading

Data Center cyber security is a fast-moving target where the IT teams need to constantly stay ahead of those that wish to do evil things. As security attacks can come from all directions, externally, and internally as well, the IT teams must fortify all the data, with a zero-trust security approach. Perimeter security augmented with intrusion detection and protection at the application level are the tools of choice for most data centers. This protects outsiders from getting in, as well as ensuring that the applications do not get impacted by a virus or other forms of malicious activities.
What has not been addressed is the intercommunications of applications amongst themselves, especially within the hypervisor layer, where virtual machines are communicating in an East-West traffic pattern. Traffic never hits the perimeter, and the conversations are happening several layers below the application layers where IDS sits. East-west traffic, from within the data center, has been an area overlooked as there is a gap organizationally. Simply put no one is paying attention to this area of vulnerability. The network infrastructure security teams are fortifying the perimeter, while the server teams are deploying IDS/IPS solutions. What has gone unnoticed is the East-West Continue reading

A little over a year ago, Nick Sullivan talked about the beginning of the end for AES-CBC cipher suites, following a plethora of attacks on this cipher mode.
Today we can safely confirm that this prediction is coming true, as for the first time ever the share of AES-CBC cipher suites on Cloudflare’s edge network dropped below that of ChaCha20-Poly1305 suites, and is fast approaching the 10% mark.
Over the course of the last six months, AES-CBC shed more than 33% of its “market” share, dropping from 20% to just 13.4%.
All of that share, went to AES-GCM, that currently encrypts over 71.2% of all connections. ChaCha20-Poly1305 is stable, with 15.3% of all connections opting for that cipher. Surprisingly 3DES is still around, with 0.1% of the connections.
The internal AES-CBC cipher suite breakdown as follows:
The majority of AES-CBC connections use ECDHE-RSA or RSA key exchange, and not ECDHE-ECDSA, which implies that we mostly deal with older clients.
In other good new, the use of ECDSA surpassed that of RSA at the beginning of the year. Currently more than 60% of all connections use Continue reading
It's a 'Swiss Army Knife' for federal cloud security compliance.
With the release of NSX for vSphere® 6.3, VMware has not only introduced several key security features such as Application Rule Manager and Endpoint Monitoring, which provide deep visibility into the application, and enable a rapid zero-trust deployment, but has also achieved Corporate Firewall Certification in independent testing performed by ICSA labs, a leading third-party testing and certification body and independent division of Verizon.
VMware NSX for vSphere 6.3 has been tested against an industry-accepted standard to which a consortium of firewall vendors, end users and ICSA labs contributed, and met all the requirements in the Baseline and Corporate module of the ICSA Module Firewall Certification Criteria version 4.2.
NSX is the only true micro-segmentation platform to achieve ICSA Firewall certification — with the NSX Distributed Firewall providing kernel-based, distributed stateful firewalling, and the Edge Services Gateway providing services such as North-South firewalling, NAT, DHCP, VPN, load balancing and high availability. VMware NSX provides security controls aligned to the application and enables a Zero-Trust model, independent of network topology.
The ICSA Firewall Certification criteria focus on several key firewall aspects, including stateful services, logging and persistence. ICSA also validates Continue reading
Serverless functions are becoming mainstream.
Containers certainly face security threats that virtual machines do not.
Last year, one of the most common requests we heard from our users was to bring a Docker-native experience to their platforms. These platforms were many and varied: from cloud platforms such as AWS, Azure, Google Cloud, to server platforms such as Windows Server, desktop platforms that their developers used such as OSX and Windows 10, to mainframes and IoT platforms – the list went on.
We started working on support for these platforms, and we initially shipped Docker for Mac and Docker for Windows, followed by Docker for AWS and Docker for Azure. Most recently, we announced the beta of Docker for GCP. The customizations we applied to make Docker native for each platform have furthered the adoption of the Docker editions.
One of the issues we encountered was that for many of these platforms, the users wanted Linuxcontainer support but the platform itself did not ship with Linux included. Mac OS and Windows are two obvious examples, but cloud platforms do not ship with a standard Linux either. So it made sense for us to bundle Linux into the Docker platform to run in these places.
What we needed to bundle was a secure, lean and portable Linux Continue reading
