Most SSH hardening advice ends at the same recommendation: Disable password authentication and use SSH keys. . That's good advice. It removes entire classes of attacks, including password spraying, credential stuffing, and brute-force attempts against exposed servers. The problem is what happens next. Many administrators treat SSH keys as the finish line when they are really the beginning of the hardening process. Attackers rarely care whether they obtained access with a password or a private...

How to Secure My NetworkPrice Tag 1security advisory remote access

Most of the time, nobody notices. SSH authentication succeeds, no alerts are generated, and the connection looks exactly the way it did the day the key was installed. That's part of the problem. . When security teams investigate unauthorized access on Linux systems, they often focus on passwords, exposed services, or vulnerable software. Trusted access receives less attention. Yet a single forgotten or unauthorized SSH key can provide the same access as a legitimate user while attracting very...

IDS VS IPS Esm H350
How to Secure My NetworkPrice Tag 1intrusion detection application security

The wrong IPS rule can look like a security fix right up until it becomes an outage. . On Linux systems, detection and prevention are often discussed together, but they do not carry the same operational risk. One tells admins that something suspicious happened. The other can decide whether traffic is allowed to continue. That is why IDS vs IPS is not just a definition to memorize. It is a deployment decision about where to monitor, where to block, and how much confidence a team needs before...

How to Secure My NetworkPrice Tag 1unauthorized access security techniques

Exposed SSH servers are continuously hammered by brute-force attacks, password spraying, credential stuffing, and recycled passwords from infostealer dumps. Attackers rotate usernames, test weak credentials, and probe for anything that gives them initial access. The logs usually look messy long before the compromise happens. . The difficult part is separating harmless failures from actual intrusion activity. One failed login from an internal workstation rarely matters. Repeated failures...

How to Secure My NetworkPrice Tag 1security advisory incident response

The first 30 minutes after discovering a compromised Linux server usually decide how much evidence remains available. One rushed reboot or cleanup attempt can wipe logs, terminate malicious processes, or remove network activity that investigators still need to review. Attackers also do not usually stay on one system for long once access is established. Early response is mostly about preserving visibility. Collect process information. Save network connections. Limit access carefully before...

Install Nextcloud on Ubuntu 20.04 for Your Linode Instance

Nextcloud is a powerful productivity platform that gives you access to some amazing features, such as collaborative editing, cloud file sync, private audio/video chat, email, calendar, and more! Best of all, Nextcloud is under your control and is completely customizable. In this article, we're going to be setting up our very own Nextcloud server on Linode. . Alternatively, you can also spin up a Nextcloud server by utilizing the Linode marketplace, which you can use to set up Nextcloud in a single click. However, this article will walk you through the manual installation method. While this method has more steps, by the end you'd have built your very own Nextcloud server from scratch, which will be not only a valuable learning experience - you'll become intimately familiar with the process of setting up Nextcloud. Let's get started! In order to install Nextcloud, we'll need a Linux instance to install it onto. That's the easy part - there's no shortage of Linux on Linode, so what we'll do in order to get started, is create a brand-new Ubuntu 20.04 Linode instance to serve as our base. Many of the commands we'll be using have changed since Ubuntu 20.04, so while you might be tempted to start with a newer instance, these commands were all tested on Ubuntu 20.04. And considering that Ubuntu 20.04 is supported until April of 2025, it's not a bad choice at all. . Discover the steps to install and configure Nextcloud on your own Ubuntu server for greater efficiency and management.. Nextcloud Installation, Ubuntu Server Setup, Self-Hosting Nextcloud. .
