OpenSCAP is an auditing tool that utilizes the Extensible Configuration Checklist Description Format (XCCDF). XCCDF is a standard way of expressing checklist content and defines security checklists. It also combines with other specifications such as CPE, CCE, and OVAL, to create a SCAP-expressed checklist that can be processed by SCAP-validated products.
The OWASP Zed Attack Proxy (ZAP) is one of the world’s most popular free security tools and is actively maintained by hundreds of international volunteers. It can help you automatically find security vulnerabilities in your web applications while you are developing and testing your applications. Its also a great tool for experienced pentesters to use for manual security testing.
At the first part, we've reviewed GSM (Greenbone Security Manager - Formerly OpenVAS) as a security manager or assessment tool for discovering vulnerabilities on virtual environments, the second part was more functional and we talked more about GSM. You leaned that how can you create a target on Greenboone Security Manager and scan it to discover vulnerabilities.
As I said at the end of second part of the blog post, the third part is related to resolving security issues. Any software and specially operating systems have "Hardening Guide". You must follow steps of hardening guide to reduce security vulnerabilities effect on production environments.
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.
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.
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).
