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.

Security-Enhanced Linux (SELinux) adds policy-based security to the CentOS Linux kernel. System administrators set SELinux policy rules to specify access controls to processes, users, and files. By default, SELinux denies access to objects if no policy rule explicitly allows access.

Perform these steps as a sudo-enabled user, or root. This guide has been tested on:

- CentOS 8
- CentOS 7
- CentOS 6

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.

IPv6 is a 64-bit address space that exponentially increases the network address. It was introduced when it was clear the explosive growth of the Internet couldn’t be sustained on IPv4’s 32-bit address space. Not all networks run IPv6, even though it has been available for a few decades, and sometimes leaving it enabled can cause issues.

This video will show you how to disable IPv6 on CentOS 7/RHEL 7.

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.

You can map your local drives on your Windows VPS and easily transfer the web contents from your local computer to your Windows VPS via Remote Desktop. You can explore mapped drives through Microsoft Windows Explorer and transfer the files by just copying from local computer drives and pasting them into VPS drives. This method of transferring files is far easy compared to FTP and saves lots of time.

While using windows VPS, PING, or ICMP Echo Request is the most common network troubleshooting tool to determine whether a particular host is reachable or not. The PING utility sends an ICMP Echo message to a remote computer and receives an ICMP Echo Reply message in response.

By default, Windows Firewall restricts the incoming ICMP Echo messages, preventing possible ping attacks. If you want to enable the incoming ICMP Echo messages, follow the steps below.

Docker is a platform enabling users to package and run applications in containers. Containers are isolated, similar to virtual machines, but more portable and resource-friendly. The isolation allows for the execution of many containers simultaneously on a single host.

Docker uses a client-server architecture and relies on the Docker daemon to manage the containers.

When you're working on a Linux system, numerous processes run in the background. These processes take up system resources in the form of CPU usage and time. While in most situations, the OS manages these processes automatically, sometimes a resource-intensive process can over-utilize the CPU due to heavy processing or poor development. The answer is usually to kill the process directly or limit its CPU usage to a certain limit.

Luckily on Linux, you can limit a process's CPU usage using a command-line utility called CPULimit.
