Using a proxy to feed metrics into Ganglia

The GitHub gmond-proxy project demonstrates how a simple proxy can be used to map metrics retrieved through a REST API into Ganglia's gmond TCP protocol.
The diagram shows the elements of the Ganglia monitoring system. The Ganglia server contains runs the gmetad daemon that polls for data from gmond instances and stores time series data. Trend charts are presented through the web interface. The transparent gmond-proxy replaces a native gmond daemon and delivers metrics in response to gmetad's polling requests.

The following commands install the proxy on the sFlow collector - an Ubuntu 14.04 system that is already runnig sFlow-RT:
wget https://raw.githubusercontent.com/sflow-rt/gmond-proxy/master/gmond_proxy.py
sudo mv gmond_proxy.py /etc/init.d/
sudo chown root:root /etc/init.d/gmond_proxy.py
sudo chmod 755 /etc/init.d/gmond_proxy.py
sudo service gmond_proxy.py start
sudo update-rc.d gmond_proxy.py start
The following commands install Ganglia's gmetad collector and web user interface on the Ganglia server - an Ubuntu 14.04 system:
sudo apt-get install gmetad
sudo apt-get install ganglia-webfrontend
cp /etc/ganglia-webfrontend/apache.conf /etc/apache2/sites-enabled
Next edit the /etc/ganglia/gmetad.conf file and configure the proxy as a data source: 
data_source "my cluster" sflow-rt
Restart the Apache and gmetad daemons: 
sudo service gmetad restart
sudo service apache2  Continue reading

Cyberattacks will compromise 1-in-3 healthcare records next year

Consumers will see an increase in successful cyberattacks against their online health records next year; supercomputers like IBM's Watson will reduce patient deaths and treatment costs by 10% in 2018; and virtual healthcare will soon become routine.Those are some of the predictions made by IDC's Health Insights group in a new report.The report claims that because of a legacy of lackluster electronic security in healthcare and an increase in the amount of online patient data, one in three consumers will have their healthcare records compromised by cyberattacks in 2016.To read this article in full or to leave a comment, please click here

Microsoft updates trust list after private key for Xbox Live leaks

On Tuesday, Microsoft updated their Certificate Trust List (CTL) after the private key for xboxlive.com was leaked to the Web. The company didn't explain how the leak happened, but the exposed certificates were immediately revoked and replaced."Microsoft is aware of an SSL/TLS digital certificate for *.xboxlive.com for which the private keys were inadvertently disclosed. The certificate could be used in attempts to perform man-in-the-middle attacks," the software giant explained in their advisory."To help protect customers from potentially fraudulent use of the SSL/TLS digital certificate, the certificate has been deemed no longer valid and Microsoft is updating the Certificate Trust list (CTL) for all supported releases of Microsoft Windows to remove the trust of the certificate."To read this article in full or to leave a comment, please click here

Patch Tuesday: Microsoft released 12 patches, 8 rated critical, 1 for a zero-day

Way to go! Congratulations on suffering through another year of deploying security patches. Microsoft released 12 security bulletins for the last Patch Tuesday of 2015, eight of which are rated as critical for remote code execution vulnerabilities. Hopefully none will result in exceedingly uncool changes like Microsoft snuck into Windows 10 last month to reset privacy settings and default programs.Although Microsoft regards MS15-135 only as “important,” it would be wise to jump on this one as it is the fix for a zero-day vulnerability in the Windows kernel that attackers are exploiting to escalate privilege, according to Qualys CTO Wolfgang Kandek. You wouldn’t know it by its Microsoft-rated “important” status, as Redmond’s security team mentioned that it resolves flaws in Windows kernel-mode drivers. Nils Sommer of bytegeist, working with Google Project Zero, is credited with reporting three CVE’s associated with this patch.To read this article in full or to leave a comment, please click here

Chrome for Android blocks access to malware and scam websites

If you've ever seen the scary red pages in Google Chrome that prevent you from visiting a dangerous website, and wished you had them on your phone, then you're in luck: Google has extended Safe Browsing, the technology behind those security alerts, to Android.Safe Browsing is now integrated into Google Play Services, starting with version 8.1, and apps are able to use it. Chrome for Android is the first to do so.As in the desktop version of Chrome, Safe Browsing protects against websites that are known to host malware, potentially unwanted programs as well as phishing and other scams.If you've surfed from an Android phone extensively you've probably been bombarded with persistent ads claiming that your phone is not running properly, that your battery drains too fast or that the device is insecure. All of them try to push some application that allegedly solves the made-up problems.To read this article in full or to leave a comment, please click here

Darkode forum is back, but a shadow of its former self

Last summer, law enforcement agencies from 20 countries joined forces to shut down the notorious Darkode hacking forum. Organizers said they would be back, stronger than ever.Security researchers have been keeping an eye out for its resurgence ever since and finally found it last week, but instead of being stronger than ever, it's actually insecure and badly configured.According to Loucif Kharouni, senior threat researcher at Damballa, it feels like a "bad Darkode imitation" that is "just not worth anyone's time."At its peak, Darkode had hundreds of users who were heavy-weights in the cybercriminal world.To read this article in full or to leave a comment, please click here
