Virtual Environments Vulnerability Assessment By GSM (OpenVAS) - Part 2 0

Virtual Environments Vulnerability Assessment By GSM (OpenVAS) – Part 2

We have reviewed reasons of have Vulnerability Assessment or Vulnerability Manager in virtual environments and how these software help us to find vulnerabilities on any component of virtual infrastructure. We have reviewed OpenVAS or Greenbone Security Manager and talked about features and abilities.

Now, it’s time to use the GSM server that we had prepared on the previous part. In this part of blog post, we’ll configure a target (ESXi Server) on OpenVAS server, create a task for scan and find the result of scan.

I’ve installed ESXi 6U1 (3029758) on a virtual machine and there is no customized configuration, all configurations are default.

NFTables, The Next Generation of Packet Classification Framework

Over the years, XTables (IPTables, IP6Tables, ARPTables and EBTables) were using as user-space utility programs for packet filtering in Linux distributions such as Red Hat Enterprise Linux or Ubuntu. Now, Linux vendors are replacing XTables with next generation packet classification framework which called NFTables.

nftables replaces the popular {ip,ip6,arp,eb}tables. This software provides a new in-kernel packet classification framework that is based on a network-specific Virtual Machine (VM) and a new nft user-space command line tool. nftables reuses the existing Netfilter subsystems such as the existing hook infrastructure, the connection tracking system, NAT, user-space queuing and logging subsystem.

Virtual Environments Vulnerability Assessment By GSM (OpenVAS) – Part 1

In virtual environments, any vulnerability has affect on virtual infrastructure and those who get the service including internal and external services. So at least, any organization should have process to identifying vulnerabilities. Identifying vulnerabilities needs tools in IT infrastructure to scan devices, operating systems and applications and find vulnerabilities (Especially security vulnerabilities).

HPE Service Pack For ProLiant (HPE SPP) 5

HPE Service Pack For ProLiant 2018.09.0 (HPE SPP)

HPE has release “HPE Service Pack For ProLiant 2018.09.0 (HPE SPP)” for production servers and it’s available to download. The Service Pack for ProLiant (SPP) is a comprehensive systems software and firmware update solution, which is delivered as a single ISO image. This solution uses Smart Update Manager (SUM) as the deployment tool and is tested on all HPE ProLiant Gen9 and Gen10 servers as defined in the Service Pack for ProLiant Server Support Guide found at

Operating System Level Virtualization (Part 2) – Implementations Comparison

These days, everyone knows what’s Cloud Computing and cloud based services are using for speedup deployment of organizations services. Operating System Level Virtualization or Containers helping system architectures and administrators to achieve the goals. There are many implementations for containers that today, those methods are compatible with different hardware architectures and operating system.

You may know that Unix has OS Level Virtualization from past years and this technology is very older than other virtualization such as Full Virtualization or Paravirtulization.

Full Virtualization (VMware ESXi, Hyper-V) and Paravirtualization (Xen, UML) provides different guest OS but there is no way to use different guest OS when you are using containers. Of curse, some solutions are under development.
