In July 2017, during an investigation, suspicious DNS requests were identified in a partnerrsquo;s network.

The source of the queries was a software package produced by NetSarang. Our analysis showed that recent versions of the software had been surreptitiously modified to include an encrypted payload that could be remotely activated by a knowledgeable attacker.
Today, a dangerous new trend is emerging: steganography is increasingly being used by actors creating malware and cyber-espionage tools. Most modern anti-malware solutions provide little, if any, protection from steganography, while any carrier in which a payload can be secretly carried poses a potential threat.
As a junior network engineer at a university I wrote a lot of management scripts in Perl.  I had scripts to do things such as check switchport configurations and upgrade switch code.

Times have changed a lot since then.

The universityrsquo;s web server now runs in the cloud, rather than on my personal workstation, and Python hasnbsp;surpassednbsp;Perl  as the scripting language du jour. Network automation now has a major focus with Python as an extremely important tool.Today Irsquo;m going to show you how to use Python scripts hosted on the box and integrated into IOS.

This is far more powerful than my earlier-career scripts, and I have some simple examples for PCI compliance, Dynamic DNS ACL updates, and configuration validation.To read this article in full or to leave a comment, please click here
DNS is all fine and dandy, but with a good Hosts file you can speed up your internet experience by eliminating time-wasting links.
Certificate Transparency and OCSP Must-Staple can't get here fast enough.
Patch available for high priority issue affecting the Linux init daemon systemd.
PS, Alpine users, you need to get patching, too – for other reasons Systemd, the Linux world's favorite init monolith, can be potentially crashed or hijacked by malicious DNS servers. Patches are available to address the security flaw, and should be installed ASAP if you're affected.…
According to Gartner, there are currently over 6 billion IoT devices on the planet. Such a huge number of potentially vulnerable gadgets could not possibly go unnoticed by cybercriminals. As of May 2017, Kaspersky Lab’s collections included several thousand different malware samples for IoT devices, about half of which were detected in 2017.
Microsoft's NetBIOS naming is vulnerable: use DNS instead Sysadmins should already have purged WINS from their Microsoft Windows Server environments – but if they haven't, there's a new reason to take it for one last walk out behind the shed.…
Domain Name Services is too important to do without, so we better make sure it's reliable and incorruptible
 (CNCF), which seeks to drive large-scale cloud computing with an emphasis on containers and microservices, has just added the Container Network Interface (CNI) project to its fold.The project joins others hosted by the nonprofit foundation, including the Kuberrnetes container orchestration platformnbsp;and CoreDNS DNS server.

CNI had been a GitHub open source project.
It features a specification and libraries to write plugins for configuring networking interfaces in Linux containers.[ To the cloud! Real-world container migrations. | Dig into the the red-hot open source framework in InfoWorldrsquo;s beginnerrsquo;s guide to Docker. ]The foundationrsquo;s adoption of CNI is meant to increase its focus on network connectivity of containers and the removal of allocated sources when the container is deleted. “The idea [is] that CNI is a standard way of being able to use different networking technologies,” said Dan Kohn, the foundationrsquo;s executive director.To read this article in full or to leave a comment, please click here
