Microsoft to disable TLS 1.0 and TLS 1.1 support in Edge and Internet Explorer

Published

on


UPDATE: Hours after Microsoft’s announcement, Google and Apple announced similar plans to drop TLS 1.0 and TLS 1.1 support. Mozilla was expected to make a similar announcement later in the day. Original article below.

Microsoft announced plans today to disable Transport Layer Security (TLS) 1.0 and 1.1 support in the Edge and Internet Explorer browsers in the first half of 2020.

“January 19th of next year marks the 20th anniversary of TLS 1.0, the inaugural version of the protocol that encrypts and authenticates secure connections across the web,” said Kyle Pflug, Senior Program Manager for Microsoft Edge.

“Two decades is a long time for a security technology to stand unmodified,” he said. “While we aren’t aware of significant vulnerabilities with our up-to-date implementations of TLS 1.0 and TLS 1.1 […] moving to newer versions helps ensure a more secure Web for everyone.”

The move comes as the Internet Engineering Task Force (IETF) –the organization that develops and promotes Internet standards– is hosting discussions to formally deprecated both TLS 1.0 and 1.1.

Microsoft is currently working on adding support for the official version of the recently-approved TLS 1.3 standard. Edge already supports draft versions of TLS 1.3, but not yet the final TLS 1.3 version approved in March, this year.

Microsoft engineers don’t seem to be losing any sleep over their decision to remove both standards from Edge and IE. The company cites public stats from SSL Labs showing that 94 percent of the Internet’s sites have already moved to using TLS 1.2, leaving very few sites on the older standard versions.

“Less than one percent of daily connections in Microsoft Edge are using TLS 1.0 or 1.1,” Pflug said, also citing internal stats.

Windows users and system administrators can test the impact of having TLS 1.0 and TLS 1.1 disabled right now and prepare their devices and networks before the final deadline.

They can do this by accessing the “Internet Options”setting in the Windows control panel, visiting the “Advanced” tab, and unticking the “Use TLS 1.0” and “Use TLS 1.1” options in the Security section.

The Five Pillars of (Azure) Cloud-based Application Security

Published

on

This 1-hour webinar from GigaOm brings together experts in Azure cloud application migration and security, featuring GigaOm analyst Jon Collins and special guests from Fortinet, Director of Product Marketing for Public Cloud, Daniel Schrader, and Global Director of Public Cloud Architecture and Engineering, Aidan Walden.

These interesting times have accelerated the drive towards digital transformation, application rationalization, and migration to cloud-based architectures. Enterprise organizations are looking to increase efficiency, but without impacting performance or increasing risk, either from infrastructure resilience or end-user behaviors.

Success requires a combination of best practice and appropriate use of technology, depending on where the organization is on its cloud journey. Elements such as zero-trust access and security-driven networking need to be deployed in parallel with security-first operations, breach prevention and response.

If you are looking to migrate applications to the cloud and want to be sure your approach maximizes delivery whilst minimizing risk, this webinar is for you.

Data Management and Secure Data Storage for the Enterprise

Published

on

This free 1-hour webinar from GigaOm Research brings together experts in data management and security, featuring GigaOm Analyst Enrico Signoretti and special guest from RackTop Systems, Jonathan Halstuch. The discussion will focus on data storage and how to protect data against cyberattacks.

Most of the recent news coverage and analysis of cyberattacks focus on hackers getting access and control of critical systems. Yet rarely is it mentioned that the most valuable asset for the organizations under attack is the data contained in these systems.

In this webinar, you will learn about the risks and costs of a poor data security management approach, and how to improve your data storage to prevent and mitigate the consequences of a compromised infrastructure.

CISO Podcast: Talking Anti-Phishing Solutions

Published

on

Simon Gibson earlier this year published the report, “GigaOm Radar for Phishing Prevention and Detection,” which assessed more than a dozen security solutions focused on detecting and mitigating email-borne threats and vulnerabilities. As Gibson noted in his report, email remains a prime vector for attack, reflecting the strategic role it plays in corporate communications.

Earlier this week, Gibson’s report was a featured topic of discussions on David Spark’s popular CISO Security Vendor Relationship Podcast. In it, Spark interviewed a pair of chief information security officers—Mike Johnson, CISO for SalesForce, and James Dolph, CISO for Guidewire Software—to get their take on the role of anti-phishing solutions.

“I want to first give GigaOm some credit here for really pointing out the need to decide what to do with detections,” Johnson said when asked for his thoughts about selecting an anti-phishing tool. “I think a lot of companies charge into a solution for anti-phishing without thinking about what they are going to do when the thing triggers.”

As Johnson noted, the needs and vulnerabilities of a large organization aligned on Microsoft 365 are very different from those of a smaller outfit working with GSuite. A malicious Excel macro-laden file, for example, poses a credible threat to a Microsoft shop and therefore argues for a detonation solution to detect and neutralize malicious payloads before they can spread and morph. On the other hand, a smaller company is more exposed to business email compromise (BEC) attacks, since spending authority is often spread among many employees in these businesses.

Gibson’s radar report describes both in-line and out-of-band solutions, but Johnson said cloud-aligned infrastructures argue against traditional in-line schemes.

“If you put an in-line solution in front of [Microsoft] 365 or in front of GSuite, you are likely decreasing your reliability, because you’ve now introduced this single point of failure. Google and Microsoft have this massive amount of reliability that is built in,” Johnson said.

So how should IT decision makers go about selecting an anti-phishing solution? Dolph answered that question with a series of questions of his own:

“Does it nail the basics? Does it fit with the technologies we have in place? And then secondarily, is it reliable, is it tunable, is it manageable?” he asked. “Because it can add a lot overhead, especially if you have a small team if these tools are really disruptive to the email flow.”

Dolph concluded by noting that it’s important for solutions to provide insight that can help organizations target their protections, as well as support both training and awareness around threats. Finally, he urged organizations to consider how they can measure the effectiveness of solutions.

“I may look at other solutions in the future and how do I compare those solutions to the benchmark of what we have in place?”
