Three critical considerations when optimizing infrastructure for application performance

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.

Overprovisioning has been the go-to approach for ensuring infrastructure and application performance. But when performance degradations and unplanned outages occur, even the most experienced teams move into “react-and-guess” mode.

Threat intelligence needs to grow up

Security teams are overwhelmed with a massive amount of threat data. While a decade ago no one was talking about threat intelligence except government agencies, organizations are now bombarded with threat data leaving them challenged with identifying what is relevant.Aggregating that data requires a shift in mindset and a maturing of threat intelligence in order to better mitigate risks.Experts say that collecting data for the purposes of having data does no good and can actually detract from a security intelligence program by using up time and man power to analyze data that is most often noise rather than real indicators of threat.MORE ON CSO:10 tips to make sure you are ready when a disaster strikes If the long-term goal of enterprises is to have mature threat intelligence programs, they need to conduct an internal risk assessment and design a plan of action.To read this article in full or to leave a comment, please click here

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.
