Cloud Active Defense: Open-source cloud protection

Category: Cloud computing,Open Networkdisc7 @ 9:39 am

Cloud Active Defense is an open-source solution that integrates decoys into cloud infrastructure. It creates a dilemma for attackers: risk attacking and being detected immediately, or avoid the traps and reduce their effectiveness. Anyone, including small companies, can use it at no cost and start receiving high-signal alerts.

Where honeypots are good at detecting lateral movement once the initial application has been compromised, Cloud Active Defense brings the deception directly into that initial application.

“We do this by injecting decoys into HTTP responses. These decoys are invisible to regular users and very tempting to attackers. This creates a situation where attackers must constantly guess: is that a trap or an exploitation path? This guessing slows down the attack operation and can lead attackers to ignore valid attack vectors as they suspect them to be traps. Furthermore, since the application’s replies cannot be 100% trusted anymore, find-tuning your exploit payload becomes painful,” Cédric Hébert, CISO – Innovation at SAP and developer of Cloud Active Defense, told Help Net Security.

Future plans and download

“In the short term, we plan to make it easy to ingest the generated alerts to a SIEM system for faster response. We also plan to release code to make it simple to deploy on a Kubernetes cluster, where each application can be configured independently. In the mid-term, we want to work on proposing response strategies: surely, banning the IP address can be an option, but what we envision is, upon detection, to give the possibility to route the active session to a clone of the application where no more harm can be done,” Hebert concluded.

Cloud Active Defense is available for free on GitHub.

Virtualization and compliance

Category: Cloud computing,VirtualizationDISC @ 1:04 am

Virtualization madness
Image by lodev via Flickr

The core technology utilized in the cloud computing is virtualization. Some organization may not want to jump into cloud computing because of inherent risks can take a shot at virtualization in their data centers. Virtualization can be utilized to reduce hardware cost and utility cost. Organization that might have 100 servers can consolidate into 10, where each physical machine will support 10 virtual systems will not only reduce the size of data center, but also hardware cost, and huge utility bill savings.

Virtualization was being utilized to increase efficiency and cost saving, which is now turning into centralized management initiative for many organizations. In centralized management patches, viruses and spam filter and new policies can be pushed to end points from central management console. Policies can be utilized to impose lock out period, USB filtering and initiate backup routines, where policies can take effect immediately or next time when user check in with the server.

The way virtualization works is OS sits on an open source hypervisor which provides 100% hardware abstractions where drivers become irrelevant. With OS image backed up at management console, which allows virtualization technology a seamless failover and high availability for desktop and servers.

As I mentioned earlier, virtualization allows enforcing of policies on end points (desktops). As we know compliance drive security agenda. If these policies are granular enough which can be map to existing regulations and standards (SOX, PCI and HIPAA) then virtualization solution can be utilized to implement compliance controls to endpoints. It is quite alright if the mapping is not 100% that is where the compensating controls come into play. The compliance to these various regulations and standards is not a onetime process. As a matter of fact standard and regulation change over time due to different threats and requirements. True security requires nonstop assessment, remediation’s and policy changes as needed.
