How to communicate from a Linux shell: Email, instant messaging

I get a lot of questions on how to perform various tasks from a Linux shell/terminal. In the interest of making a simple cheat sheet—something I can point people to that will help them get rolling with terminal powers—what follows are my recommendations for how to perform various types of communication from your shell. I’m talking about the normal sort of communication most people perform via a web browser (or a handful of graphical applications) nowadays: Email, instant messaging, that sort of thing. Except, you know, running them entirely in a terminal—which you can run just about anywhere: in an SSH session on a remote server, on a handheld device, or even on your Android phone/tablet. To read this article in full or to leave a comment, please click here

New York State cybersecurity rules and the skills shortage

While the cybersecurity industry was knee-deep in vision, rhetoric and endless cocktail parties at the RSA Conference, the State of New York introduced new cybersecurity regulations for the financial services industry. The Department of Financial Services (DFS) rules (23 NYCRR 500) go into effect next week on March 1, 2017.Anyone who has reviewed similar cybersecurity regulations will find requirements in 23 NYCRR 500 familiar, so while the regulations are somewhat broader than others, there are obvious common threads. In reviewing the document, however, section 500.10 caught my eye. Here is the text from this section:To read this article in full or to leave a comment, please click here

EFF: Congress considers making it illegal to protect consumer privacy online

“When you go online you reveal a tremendous amount of private information about yourself,” wrote the Electronics Frontier Foundation (EFF). “What you browse, what you purchase, who you communicate with—all reveal something personal about you.” These are examples of what your ISP knows about you.But it’s more than that for people with smart connected devices. Think about a smart refrigerator. As former FCC Chairman Tom Wheeler asked, “Who would have ever imagined that what you have in your refrigerator would be information available to AT&T, Comcast, or whoever your network provider is?” Who would have thought they could sell that type of information?To read this article in full or to leave a comment, please click here

IDG Contributor Network: Breaking through the cybersecurity bubble

For many in the cybersecurity space, the world revolves around the attack vector. Many security vendors narrowly focus on their version of the prevent, defend and respond paradigm—focusing on their purported supremacy and on making their case to get a piece of the enterprise security budget pie. At the recent RSA Conference in San Francisco, however, there were some hopeful signs that this narrow view and myopic perspective is evolving—at least for some. “Don't draw lines that separate different fields. Draw connections that bring them together,” implored RSA CTO Dr. Zulfikar Ramzan in the opening keynote as he called for business-driven security. “In my experience, today's security professionals must also draw connections between security details and business objectives.”To read this article in full or to leave a comment, please click here

We finally know how much a data breach can cost

Everyone knows corporate data breaches can be expensive, but does anyone really know exactly how expensive? Recent estimates for the average cost have landed all over the map, ranging from $4 million to $7 million. But when it comes to the top end of the scale, those appraisals turn out to be laughably small.+ Also on Network World: Everything you know about cyberwar is wrong + The massive Yahoo data breaches of 2013 and 2014 now have a real cost attached to them, and it’s a couple orders of magnitude larger than those piddly estimates. Simply put, the breaches forced Yahoo to renegotiate its sale to Verizon, cutting the price by $350 million. To read this article in full or to leave a comment, please click here

Python – Kirk Byers Course Week 4 Part 1

This post will describe the exercises and solutions for week four of Kirk Byers Python for Network Engineers.

The first exercise is the following:

I. Prompt a user to input an IP address.  

Re-using some of the code from class3, exercise4--determine if the IP address is valid. 

Continue prompting the user to re-input an IP address until a valid IP address is input.

Compared to our last script we want to keep asking the user for an IP address until they supply a valid one. This means that we need a loop that can run until some condition changes. This is where While loops come in handy. We will create a Boolean variable called not_done and set this to True.

not_done = True

while not_done:

The meaning of while not_done: is that the While loop will run as long as not_done is True.

The next step is to ask the user for an IP address. We use the built-in function input() to do this.

ip_add = input("\n\nPlease enter an IP address: ")

We use another Boolean variable called valid_ip which is set to True until we prove that the IP address is not valid.

valid_ip = True

We will split Continue reading

9 new hacks coming to get you

Securitywise, the internet of things is going as badly as most computer security experts predicted. In fact, most vendors don’t fully appreciate the potential threats IoT devices pose. Anything connected to the internet and running code can be taken over for malicious purposes. Given the accelerating proliferation of internet-connected devices, we could be hurtling toward catastrophe. Personal security cameras, for example, are being used to conduct the largest denial-of-service attacks the world has ever seen, not to mention allowing strangers to spy on the very people the cameras are supposed to protect.To read this article in full or to leave a comment, please click here
