When you order your VPS, you can choose a distribution or operating system to pre-install. The server is therefore ready to use after delivery but it will be up to you as the administrator to implement measures that ensure the security and stability of your system.

WireGuard is a modern VPN (Virtual Private Network) technology that utilizes state-of-the-art cryptography. Compared to other popular VPN solutions, such as IPsec and OpenVPN, WireGuard is faster, easier to configure, and has a smaller footprint. It is cross-platform and can run almost anywhere, including Linux, Windows, Android, and macOS.

Wireguard is a peer-to-peer VPN; it does not use the client-server model. Depending on its configuration, a peer can act as a traditional server or client. It works by creating a network interface on each peer device that acts as a tunnel. Peers authenticate each other by exchanging and validating public keys, mimicking the SSH model. Public keys are mapped with a list of IP addresses that are allowed in the tunnel. The VPN traffic is encapsulated in UDP.

Users often encounter the error "VCRUNTIME140_1.dll was not found" when trying to run a specific program on Windows Server 2019, 2022, as well as other versions of the operating system.

In particular, users encounter an error when a file is missing from the system – thus, it prevents the launch and operation of programs that rely on this file. Such errors can create a very unpleasant user experience when using a Windows device.

The VCRUNTIME140_1.dll element indicates that the missing DLL file comes from the Microsoft Visual C++ Redistributable package and must be installed on the system initially. However, for several reasons, these files can be replaced, deleted, or corrupted. Therefore, users cannot launch programs on Windows.

Chkrootkit is a popular security scanner that helps administrators look for signs when a system is infected with rootkits. You can use chkrootkit to find files and rules associated with rootkits, but you cannot be 100% sure that all rootkits will be found and removed.

Ping is a network administration utility that is used to test the availability of a system on an IP network. Ping is also used to test the quality of the network connection by monitoring the round trip time and packet losses. On the other hand, network intruders and hackers also use ping to identify network subnets to find potential hosts or to perform ICMP flood attacks. Therefore, it is a good practice to block ping requests to your servers to prevent any kind of attack.

Keycloak is a free and open source Identity and Access Management solution by RedHat Community. Its aim is to secure modern applications and services without writing any code. It provides a wide range of features including multifactor authentication, SSO, centralized user management, authentication, authorization, social login, and more. Keycloak allows you to add authentication to applications and secure services with minimum fuss. You don’t need to deal with storing users or authenticating users.

Keycloak provides a single sign-out, which means users only have to log out once to be logged out of all applications that use Keycloak. Keycloak is an Identity broker as it authenticates users with existing OpenID Connect or SAML 2.0 Identity Providers. Another important feature is that Keycloak has built-in support to connect to existing LDAP or Active Directory servers.

For Monitoring Linux/Windows hosts in Zabbix Server, We need to install Zabbix Agent to our Remote Linux/Windows systems. What Zabbix Agent does? Zabbix Agent collects all the data such as (CPU usage, memory usage, network usage, HTTP usage, etc…) and sends the reports to Zabbix Server.

A DNS cache is a temporary database that stores information about previous DNS lookups. In other words, whenever you visit a website, your OS and web browser will keep a record of the domain and the corresponding IP address. This eliminates the need for repetitive queries to the remote DNS servers and allows your OS or browser to resolve the website’s URL quickly.

However, in some situations like troubleshooting network issues or after changing DNS resolvers, you will need to flush the DNS cache. This will clear the cached DNS entries and perform a subsequent lookup to resolve the domain based on newly configured DNS settings.

The Group Policy Management Console is part of the Remote Server Administration Tool (RSAT) that unifies Group Policy Management across the entire domain. So, if an administrator wants to manage the domain’s Group Policy from a Windows operating system (as opposed to a Windows Server), they will need to install the Group Policy Management Console (GPMC).

Active Directory Group Policies allow you to centrally apply the same settings for multiple computers and/or domain users and greatly simplify configuration management in an Active Directory domain environment. The GPMC is the main tool for managing Group Policy Objects (GPOs) in Active Directory.

Ubuntu Server is a variant of the Ubuntu OS that does not include a graphical user interface (GUI) by default. GUI applications consume system resources needed for server-oriented tasks, so Linux server distributions usually avoid a GUI in favor of the command-line terminal.

Some tools, however, perform better and are easier to manage with a GUI. If you use a tool with a GUI, installing a desktop environment may improve the experience of working with the server.

From Ubuntu 17.10 onwards, the way a network is configured is completely changed. In earlier versions of Ubuntu, a static file (/etc/network/interfaces) was used for configuring network interfaces. Canonical has launched a new tool called Netplan to manage network settings. Netplan is a utility that uses YAML to configure networking on a Linux system.

Enabling an SSH server on a virtual private server (VPS) will expose the server to the Internet and provide opportunities for hacking activities, especially when VPS still using root as primary access.

VPS should be configured with an email alert automatically to each successful login attempt via the SSH server. VPS server owner shall be notified of any SSH server access log, such as who, when, and which source IP address. This is an important security concern for server owners to protect the server from unknown login attempts. This is because if hackers use brute force to log into your VPS via ssh then it can be very dangerous.
