Pseudo-Math to Measure Network Fragility Risk

Some of you may have heard me ranting on Packet Pushers on stupid network tricks and why we continue to be forced to implement kluges as a result.  I made some comment about trying to come up with some metric to help measure the deviation of the network from the “golden” desired state to the dirty, dirty thing that it’s become over time due to kluges and just general lack of network hygiene.

So I decided that I would write a bit of code to get the conversation started. All code discussed is available on my github here

The Idea

What I wanted here was to create some pseudo-mathematical way of generating a measurement that can communicate to the management structure WHY the requested change is a really, really, bad idea.

Imagine these two conversations:

bad-conversation

good-conversation

Which conversation would you like to be part of?

Assumptions:

I’m making some assumptions here that I think it’s important to talk about.

  1. You have a source-of-truth defined for your network state. That is you have abstracted your network state into some YAML files or something like that.
  2. You have golden configurations defined in templates (ex Jinja2 ). These templates can be combined with your Continue reading

Trump administration is giving us a good lesson on Twitter security

Several recent incidents involving U.S. President Donald Trump's administration can teach users something about IT security -- particularly about Twitter and what not to do with it.It turns out that several White House-related Twitter accounts -- including the president's official account, @POTUS -- until recently were revealing sensitive information that hackers might be able to exploit.The problem revolves around the service’s password reset function. If the account holder doesn't take certain steps to secure it, Twitter exposes information that anyone with the right skills can use to uncover what email address -- in redacted form -- was used to secure a Twitter account.To read this article in full or to leave a comment, please click here

U.S. companies spending millions to satisfy Europe’s GDPR

Ninety-two percent of U.S. multinational companies cited compliance with the looming General Data Protection Regulation (GDPR) as a top data protection priority, according to new research from PwC. Sixty-eight percent are earmarking between $1 million and $10 million on GDPR readiness and compliance efforts, with 9 percent expecting to spend over $10 million, says Jay Cline, PwC’s U.S. privacy leader.Cline says PwC ‘slatest survey showed that fear remains the biggest motivator for U.S. CIOs, who are “connecting the dots” after watching data breaches lead to lost revenues, regulatory fines and the erosion of consumer trust. “U.S. companies see the connection between doing privacy well and greater revenues and consumer trust,” says Cline, who surveyed 200 CIOs, CISOs and other C-suite executives.To read this article in full or to leave a comment, please click here

Google wants to add AI to gadgets made using Raspberry Pi

Google wants to bring smarts to cool gadgets and devices made using Raspberry Pi 3 or Intel's Edison.The company is chasing makers with open-source tools needed to add artificial intelligence to consumer, industrial, and retail devices made using board computers.The plan may include machine-learning tools, which are central to AI. AI helps Apple's Siri, Amazon's Alexa, and Microsoft's Cortana answer questions, and also helps self-driving cars cruise the streets safely."We don't have any specifics to announce right now, but we're excited to keep sharing open-source machine learning tools with the community -- stay tuned for more this year," a Google spokesman said in an email.To read this article in full or to leave a comment, please click here

As Baby Boomers retire, the shortage of mainframe professionals grows more acute  

This column is available in a weekly newsletter called IT Best Practices.  Click here to subscribe.  For years we have been hearing about critical IT skills shortages. Companies just can’t find enough (or the right) people with expertise in mobility, cybersecurity, data storage, networking, cloud and other important areas.There’s one area, however, where the shortage is becoming acute, and affected companies that don’t act now might soon find themselves in a world of hurt. I’m talking about the business-critical discipline of mainframe stewardship.Experts have been warning about this for at least a decade, and the days of reckoning are here, driven largely by the fact that mainframe champions are retiring from the workforce in droves. People who started their IT careers in the 1970’s and 1980’s – when the mainframe was king – are now baby boomers at the end of their careers. The generations behind them took up different computing platforms, meaning there are few people to pass the mainframe torch to. By some estimates there will be more than 84,000 open positions in this field by 2020.To read this article in full or to leave a comment, please click here

Worth Reading: IPv6 server addressing strategies

In this post, I’ll discuss configuration approaches for systems that usually have been configured with “static” IP parameters in the IPv4 age/context (for example, servers in data centres). When it comes to IPv6 there are more options and we’ll have a look at their implications and potential advantages/disadvantages. —APNIC

Gmail will block JavaScript attachments, a common source of malware

Starting Feb. 13, Google will no longer allow JavaScript attachments on its Gmail service, killing one of the main methods of malware distribution over the past two years.Users will no longer be able to attach .JS files to emails in Gmail, regardless of whether they attach them directly or they include them in archives like .gz, .bz2, .zip or .tgz. For those rare cases when such files need to be shared via email, users can upload them to a storage service like Google Drive and then share the link.The .JS file extension will be added an existing list of other banned file attachments that includes: .ADE, .ADP, .BAT, .CHM, .CMD, .COM, .CPL, .EXE, .HTA, .INS, .ISP, .JAR, .JSE, .LIB, .LNK, .MDE, .MSC, .MSP, .MST, .PIF, .SCR, .SCT, .SHB, .SYS, .VB, .VBE, .VBS, .VXD, .WSC, .WSF and .WSH. Most of these file types have long been abused by cybercriminals to send malware via email.To read this article in full or to leave a comment, please click here
