Protect Virtual Machine: How to Stay Safe from Ransomware

How can we protect VM against ransomware? This is important question for any infrastructure administrator. Actually, Ransomware is a computer malware, and it will be installed on wide range of devices such as computers, smartphones and wearable devices. It can attack to data and encrypt data then ask user to pay for decrypt data. Users may encounter in a number of ways. The most common method used by attackers to spread software is via e-mail as an attached file. Protecting Virtual Machines Most companies are using VDI solutions to deliver desktop experience to the users and virtual desktops acting same as physical desktop. Even all protection steps are provided for protecting users data such as strong anti-virus, firewall, email malware detection and other ways, attackers will try new way to infect user data and keep data as hostage and ask to pay money. When users data is encrypted by a Ransomware, administrators can help them by restoring their data from a valid backup, so one of solutions to protecting data is taking backup from them. Traditional Backup Administrators can ask users to keep their important data on shared folder or removable devices or sync them with same folders on other computers. But this is...

VMware Hardware Version 13

Each new version of vSphere includes some improvements and new features and many of them will be applied on virtual machines. The improvements and features will be add to “Hardware Version” and you be able to use those, if you use latest “Hardware Version”. It’s strongly recommended that don’t upgrade your hardware version to latest just when you need to use a specific feature or expand hardware resources that older hardware version doesn’t support that. Because “Hardware Version” doesn’t have any compatibility with older ESXi and if you have mixed cluster, you can’t use latest hardware version. Here is an example: You have a cluster and the cluster contains some ESXi 6.5, 6.0 and 5.5. If you upgrade hardware version to 11, your virtual machine will be hosted by ESXi 6.0, ESXi 6.5 and the machine will not be migrated on ESXi 5.5. So, keep your hardware version compatible with oldest ESXi in your environment. You can downgrade hardware version but it’s not recommended. For make sure about hardware version, you can change default version on your cluster anytime. Let’s review new hardware version, compare it with older versions and compatibility with ESXi: Feature ESXi 6.5 and later ESXi 6.0...

ESXi Reliable Memory Technology

VMware has introduced new feature for kernel protection against memory error in ESXi. VMware called the new feature: Reliable Memory Technology or RTM. The feature is one of new features in ESXi 5.5! ESXi use a zone of memory that it’s more reliable than other offsets of memory, so risk of PSOD will be reduced. Also when part of memory has error, ESXi will stop to using the part of memory. There is some other technique against memory corruption or memory health error such as memory mirroring but Reliable Memory Technology can help you on this regard without loosing half of your memory capacity. Because memory mirroring is just like to RAID 1 on hard disks. Dell has introduced another feature on its server by using Reliable Memory Technology and called the new feature: Fault Resilient Memory or FRM. Fault Resilient Memory will provide “Fault Resilient Zone” and ESXi will put its kernel to the zone. The features can protect ESXi kernel and VMs as well. So if you have critical service on a VM, you can force ESXi to keep its memory on RTM or FRM zone to avoid memory error and down time for the machine. You can configure...

VMware Fling – ESXi Embedded Host Client

Few years ago, you have to install vSphere Client on a Windows machine to manage your standalone ESXi server or connect to your server via SSH and run your commands to do something. VMware engineers are working on some unofficial projects and calling them “Fling”, most of them are favorite to me and you can do anything that you can’t do by using standard software or even third-party software. The engineers was working on a good, very good software and it has been released one year ago. ESXi Embedded Host Client is the software and it’s like vSphere Web Client but it doesn’t support vCenter. You can do any action which are available on vSphere Client for a ESXi such as creating new VMs, managing hardware, security, networks and etc. You can find this explanation on VMware Labs: The ESXi Embedded Host Client is a native HTML and JavaScript application and is served directly from your ESXi host!

VSFTPD Configuration – RedHat Enterprise 6.x

Past week, I had to research and learn about “VSFTPD” and implement SFTP server for one of our customers. I want to share the instructions and my experiences about that. May be, It will help you in future. What is “VSFTPD”? “VSFTPD”, (or very secure FTP daemon) is an FTP server for Unix-like systems, including Linux. It is licensed under the GNU General Public License. It supports IPv6 and SSL. “VSFTPD” supports explicit (since 2.0.0) and implicit (since 2.1.0) FTPS. “VSFTPD” is the default FTP server in the Ubuntu, CentOS, Fedora, NimbleX, Slackware and RHEL Linux distributions. What is scenario? We need to create an user for SFTP connection and restrict the user in the user’s home directory. The user can put files to “Outgoing” directory for upload and put files to “Incoming” directory for download. The directories are in “/home/the_user_folder/” and the user will be restricted and the user can’t create directory in home directory but can create directory in “Incoming” and “Outgoing” directories. Implementation First Step, Installation In order to implement VSFTPD server, we need to install two packages: OpenSSL VSFTPD You can install them by YUM or by RPM. Like this: rpm -i /media/RHEL-6.8\ Server.x86_64/Packages/openssl098e-0.9.8e-20.el6_7.1.x86_64.rpm rpm -i...
