SSH servers are a common target for brute-force attacks. This is even more true if your infrastructure sits behind an SSH bastion because attackers have no choice but to compromise the bastion host either by exploitation or denial of service. In this article, we will list a few controls which will help you harden your SSH servers from brute- force attacks.
SSH bastion hosts are an indispensable security enforcement stack for secure infrastructure access. Every security compliance standard that deals with remote infrastructure access (e.g., FedRAMP AC-17 - Remote Access, HIPAA §164.312(a)(1) - Access control, SOC2 CC6.1 - Manage Points of Access) mandates preventing direct network access to the servers and APIs.
2022 feels a little different, doesn’t it? Every day I’m prepared to hear something new, something scary, or something exciting. These last couple of years have made it seem like we just never know what is coming next. It’s no different for financial services companies who have to be prepared for the unexpected, including disruptive technologies that can challenge their core businesses.
Many market-leading companies who have dominated their respective sectors with hardware or on-prem/installable software solutions are turning to SaaS offerings to fuel the next phase of their growth. Why? Simple. Market valuations are much higher for SaaS companies than they are for traditional software and hardware companies. The median multiple on earnings for a SaaS company is 12.7x as of Q3 2021 according to venture capitalist Jamin Ball who tracks the Public Cloud Software (e.g.
One way to enhance SSH login security is by using two-factor authentication (2FA). This approach forces an administrator to self-identify with an additional security verification in addition to the local admin credentials. This tutorial guides you through setting up Google Authenticator PAM to enable 2FA for users connecting to SSH on a Linux server. We’ll use nano as our editor in examples.
SSH client configuration files allow us to connect to servers with pre-configured commands. This saves typing each SSH command parameter when logging into a remote machine and executing commands on a remote device. This article will examine secure shell (SSH) client configuration (config) files and their functions. Specifically, we will show an example of an SSH client config file to learn how to use these files before creating an example config file that connects to a fictitious server.
Strictly following security best practices is the first step to cybersecurity. Although SSH is the industry standard for both security and efficacy for remote server access, as with any software, SSH is only as secure as configurations applied to the server and client configurations. In this article, we’ll explore five SSH best practices you should observe to boost the security of your infrastructure.
Audit logging for SSH is essential for system security, and it’s often an important part of compliance regulations. Developers and administrators should only be granted access to the resources they need, and a continuous monitoring system should be in place to ensure that they aren’t abusing that access.
I talk to a lot of engineers every day. SREs. Systems Architects. Security Engineers. What I am hearing from them is that they are moving away from passwords — both in their personal lives, opting for more secure forms of authentication like biometrics and second factors, and at work. It just doesn’t make sense anymore to protect your personal bank with a second factor, but to share around an SSH key to access critical server infrastructure.
