IMUNES on Linux

The IMUNES open-source network simulator can now be installed on and run on Linux. Previously, IMUNES was available only for the FreeBSD operating system.

IMUNES-linux

The Linux version of IMUNES is ready to be used and can set up and run network emulation scenarios. It does not yet have all the features offered in the FreeBSD version of IMUNES but the development team intends make add in more features until both versions support similar capabilities.

In this post, we will show how to install the Linux version of IMUNES on Ubuntu 14.04, look at the tool set used by IMUNES on Linux, and experiment with a simple network simulation scenario.

Compatibility with Linux versions

IMUNES is compatible with all popular Linux distributions.

The IMUNES development team seems to be testing IMUNEs on the latest available Linux distributions. If you are using Linux distributions like Ubuntu 15.04, you can follow the standard IMUNES install directions. However, if you are using a long-term-supported distribution like Ubuntu 14.04, there are some extra software dependencies that you must install.

Risky Business #378 — Mary Ann Davidson vs Krebs and Dowd

On this week's show we're chatting with Mark Dowd and Brian Krebs about Oracle CSO Mary Ann Davidson's somewhat odd blog post from earlier this week. In the post she laid into security researchers for violating Oracle's EULA when reverse engineering their products. The post got pulled, much drama, we sift through the ashes of that. Plus we chat to Brian about the daring $46.7m online heist against Ubiquiti Networks.

Updates are coming for a telematics unit that hacked a Corvette

Security updates are being distributed for a telematics control unit (TCU) that security researchers showed could be manipulated to remotely apply the brakes of a Corvette, according to the device’s French manufacturer.The device is a small dongle that plugs into the On-Board Diagnostics II (OBD-II) port on a vehicle, usually located under the driver’s side dashboard. TCUs with cellular connections are increasingly being used in vehicles by insurance companies to monitor drivers or for fleet management.At the USENIX security conference this week in Washington, D.C., academics from the University of California demonstrated how a C4E family dongle from Paris-based Mobile Devices Ingenierie could be remotely accessed.To read this article in full or to leave a comment, please click here

Using Vagrant with CumulusVX

Cumulus recently announced their CumulusVX platform, which is a virtualized instance of their operating system typically found on network switches. They’ve provided a few options to run this, and in this blog post, I’ll be exploring the use of Vagrant to set up a topology with Cumulus virtual devices. Brief Review of Vagrant In software development, there is a very crucial need to consistently and repeatably set up development and test environments.

Brief Review of Vagrant

In software development, there is a very crucial need to consistently and repeatably set up development and test environments. We’ve had the “but it worked on my laptop” problem for a while, and anything to simplify the environment set up and ensure that everyone is on the same page will help prevent it.

Vagrant is a tool aimed at doing exactly this. By providing a simple CLI interface on top of your favorite hypervisor (i.e. Virtualbox) you can distribute Vagrantfiles, which are essentially smally Ruby scripts, and they provide the logic needed to set up the environment the way you want it. In addition, it can call external automation tools like Ansible and Puppet to go one step further, and actually interact with the operating system itself to perform tasks like installing and configuring software.

Use SAP’s mobile platform? Patch now to avoid these ‘high risk’ vulnerabilities

Three high risk vulnerabilities in SAP Mobile could give attackers access to encrypted information stored in mobile devices, security firm Onapsis reported Wednesday.All three vulnerabilities were recently fixed by SAP, but systems are only safe if the patches are applied.“SAP runs so many of the world’s largest enterprises that any vulnerability must be taken very seriously,” said Nicholas Taylor, CEO of Netlogx, another security provider.One of the flaws enables keystream recovery and could allow an attacker with access to a vulnerable device to decrypt credentials and other sensitive information stored within, Onapsis said. The attacker could then potentially connect to other business systems to access additional data.To read this article in full or to leave a comment, please click here

DOJ calls for encryption balance that includes law enforcement needs

It’s possible for companies to design their encryption systems to allow law enforcement agencies to access customer data with court-ordered warrants while still offering solid security, U.S. Department of Justice officials said.When DOJ and FBI officials raised recent concerns over end-to-end encryption on Android and iOS mobile phones, some security experts suggested it was difficult or unsafe to build in provider access to encrypted consumer data. But many companies already offer encryption while retaining some access to user information, two senior DOJ officials said Wednesday.To read this article in full or to leave a comment, please click here

Dropbox adds U2F support for better security

Two-factor authentication is often held up as a best practice for security in the online world, but Dropbox on Wednesday announced a new feature that’s designed to make it even tougher.Whereas two-step verification most commonly involves the user’s phone for the second authentication method, Dropbox’s new U2F support adds a new means of authenticating the user via Universal 2nd Factor (U2F) security keys instead.What that means is that users can now use a USB key as an additional means to prove who they are.“This is a very good advancement and adds extra security over mobile notifications for two-factor authentication,” said Rich Mogull, CEO with Securosis.To read this article in full or to leave a comment, please click here
