First, let’s define what a port is. According to the IEFT, a port is:
“A logical entity for Internet communication. Ports serve two main purposes: 1. They provide a demultiplexing identifier to separate transport sessions between the same pair of endpoints 2. They may also identify the application protocol and associated service to which processes connect.”
In plain English, this simply means that a port is an endpoint through which data flows back and forth between two computers over a network. A computer has 65535 ports available to share information. These port numbers are based on a 16-bit number, which is where we derive the total number of available ports (0 to 65535).
Initially developed by Datawire, Telepresence is a new open-source tool supported by the CNCF (Cloud Native Computing Foundation). It allows developers to run local software while connected to a remote Kubernetes cluster. The application uses a two-way network proxy to simulate TCP connections, environmental variables, and other volumes of services as local processes. This link allows for remote work to be accomplished while seemingly local to the cluster via the proxied connection.
While there are many ways to make sure your server is as secure as possible, there are some basic steps that we can take to increase security. Users with a Linux server can change their SSH port to something other than the default port (22). The steps listed below, outline this task providing steps to enable this change.
Liquid Web’s new Cloud Platform is an environment designed with website uptime, ease of use, and scalability in mind. It combines the easy-to-use cPanel-based environment with a Load Balancing solution. It can be adjusted to suit your specific online needs. This platform is also included in our Fully Managed Support. Experienced webmasters or developers can opt for our Core-Managed environment, using the LAMP stack (Linux, Apache, MySQL/MariaDB, PHP).
Zero Trust security is the concept, methodology, and threat model that assumes no user, system, or service operating within a secured internal environment should be automatically trusted. It put forward that every interaction must be verified when trying to connect to a system before being granted access. This concept uses micro-segmentation, and granular edge controls based on user rights, application access levels, service usage, and relation to the location to determine whether to trust a user, machine, or application seeking to access a specific part of an organization.
In this tutorial, we will look at several methods that are used to compromise a website. In today’s world, websites use multiple procedures that represent the core functions of a modern business. Whether you have an eCommerce site or a business card site, a website is essential for driving business growth. We can safely state that a website is a unique image of your respective business.
The systemctl command is a utility which is responsible for examining and controlling the systemd system and service manager. It is a collection of system management libraries, utilities and daemons which function as a successor to the System V init daemon. The new systemctl commands have proven quite useful in managing a servers services. It provides detailed information about specific systemd services, and others that have server-wide utilization.
OpenSSH is an open-source utility developed by The OpenBSD Project. SSH stands for “Secure SHell.” This service encrypts traffic on both ends, eliminating security risks from hackers or eavesdroppers. It can be used for remote operations like file transfers and offers key-based passwordless authentication. In this tutorial, we will demonstrate how to harness the power of SSH’s on your Windows server to send basic remote commands and transfer files using password authentication.
