Why are browsers so bad after 26 years?

We all live in a browser if we use the internet. You're in one right now if you're reading this. And it's not a new piece of software. Sir Tim Berners-Lee first introduced us to the Mosaic browser in 1990. And despite 26 years of development, the browser remains the worst piece of software we use on a daily basis.Broke. Buggy. Bloated. Hogging memory. Crash-prone. Susceptible to malware. Lousy HTML rendering. I could go on and on with a litany of poorly constructed sentences describing the current state of browsers, but you get the idea. + Also on Network World: Windows 10 browser beatdown: Who’s got the edge? + Browsers aren't just for watching YouTube videos or visiting news sites, either. With the on-demand world of SaaS, browsers are the portal into important line-of-business software, even if the high priest of SaaS, Marc Benioff, hates that word. To read this article in full or to leave a comment, please click here

Using big data for security only provides insight, not protection

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.Cybersecurity experts are excited about big data because it is the “crime scene investigator” of data science. If your organization is hacked and customer information compromised, your use of big data to collect massive amounts of information on your systems, users and customers makes it possible for data analysts to provide insight into what went wrong.But while big data can help solve the crime after it occurred, it doesn’t help prevent it in the first place. You’re still left cleaning up the mess left behind by the breach: angry customers, possible compliance issues with data privacy standards like HIPAA and PCI DSS, maybe even government fines and class-action lawsuits.To read this article in full or to leave a comment, please click here

Worth Investigating: My Looking Glass Tool

If you're a networking engineer, sysadmin, or NetDevOps guru preferring the power of CLI over carpal-syndrome-inducing GUI you might like the My Looking Glass tool developed by Mehrdad Arshad Rad. Haven't tried it out, but the intro on GitHub page looks promising.

So you want to expose Go on the Internet

This piece was originally written for the Gopher Academy advent series. We are grateful to them for allowing us to republish it here.

Back when crypto/tls was slow and net/http young, the general wisdom was to always put Go servers behind a reverse proxy like NGINX. That's not necessary anymore!

At Cloudflare we recently experimented with exposing pure Go services to the hostile wide area network. With the Go 1.8 release, net/http and crypto/tls proved to be stable, performant and flexible.

However, the defaults are tuned for local services. In this articles we'll see how to tune and harden a Go server for Internet exposure.

crypto/tls

You're not running an insecure HTTP server on the Internet in 2016. So you need crypto/tls. The good news is that it's now really fast (as you've seen in a previous advent article), and its security track record so far is excellent.

The default settings resemble the Intermediate recommended configuration of the Mozilla guidelines. However, you should still set PreferServerCipherSuites to ensure safer and faster cipher suites are preferred, and CurvePreferences to avoid unoptimized curves: a client using CurveP384 would cause up to a second of CPU to be consumed on our Continue reading

Corporate boards aren’t prepared for cyberattacks

Major cyberattacks against organizations of all sizes seem to happen almost weekly. On Dec. 14, Yahoo announced the largest-ever data breach, involving more than 1 billion customer accounts.Despite the scale and potential harm from such attacks, there's wide recognition that corporate leaders, especially boards of directors, aren't taking the necessary actions to defend their companies against such attacks. It's not just a problem of finding the right cyber-defense tools and services, but also one of management awareness and security acumen at the highest level, namely corporate boards.To read this article in full or to leave a comment, please click here
