   This is a walkthough for installing and configuring OpenVAS (GVM) on CentOS 7. OpenVAS (Open Vulnerability Assessment System) is an opensource vulnerability scanner. Update 20April2019: Greenbone is deprecating OpenVAS version 9 and version 10 is now known as Greenbone Vulnerability Manager (GVM). Likewise, the new rpms are called ‘greenbone-vulnerability-manager’ and ‘gvm-libs’ which replace the ‘openvas’ and ‘openvas-libraries’ rpms. I f you are upgrading from 9 to the latest version, you may lose your previous tasks and reports so beware! Also, if you are still on version 9 and you simply need a temporary workaround for “Report outdated Scan Engine / Environment (local)” error, scroll to the bottom.  Brief History OpenVAS forked from Nessus when Tenable took the previously opensource product to closed source back in 2005. That’s worth mentioning primarily because on a side note, I’ve used Nessus for many years and I remember when it was forked. Since then, Nes

Logical Volume Management ( LVM ) makes it easier to manage disk space. If a file system needs more space, it can be added to its logical volumes from the free spaces in its volume group and the file system can be re-sized as we wish. If a disk starts to fail, replacement disk can be registered as a physical volume with the volume group and the logical volumes extents can be migrated to the new disk without data loss. Create LVM Storage in Linux In a modern world every Server needs more space day by day for that we need to expand depending on our needs. Logical volumes can be use in RAID, SAN. A Physical Disk will be grouped to create a volume Group. Inside volume group we need to slice the space to create Logical volumes. While using logical volumes we can extend across multiple disks, logical volumes or reduce logical volumes in size with some commands without reformatting and re-partitioning the current disk. Volumes can stripes data across multiple disks this
