In today’s digital era, cybersecurity has become a major concern for individuals and organizations alike. One key aspect of securing systems is controlling access to digital devices and data. This is where the concepts of authentication and authorization come into play. In this article, we will explain what authentication and authorization are, the key differences
Networks are now involved in nearly every event that occurs in our interconnected world. Whether you’re playing online games, hosting a website, or accessing a home security camera, network management should interface those activities. One technique that helps enable any of those activities is port forwarding. What is Port Forwarding? Port forwarding (also known as
CVE-2025-61984 is a newly discovered OpenSSH client command injection vulnerability that affects OpenSSH client versions prior to 10.1. This article focuses on what CVE-2025-61984 is, the root cause of the vulnerability, and how to mitigate it. Root cause of CVE-2025-61984 OpenSSH includes a ProxyCommand option in its ssh_config file, which allows administrators to run an
In this digitally first world, organizations interacts with a large number of users everyday, whether it being customers, partners, employees or contractors with most of them needing safe access to the confidential systems and data. It is very difficult to manage this access manually, which is where the Identity and Access management comes into play.Management
As cybersecurity threats continue to rise, traditional passwords are no longer enough to protect sensitive accounts and data. Traditional two-factor authentication (2FA) methods like SMS codes or authenticator apps were once considered strong defences, modern cyber threats have exposed their weaknesses. Attackers have learned how to intercept SMS, phish OTP codes, and even hijack authentication
Just-in-time (JIT) access is a modern security practice which reduces risk by granting users privileges only when it is required and for a specific period, eliminating permanent access found in legacy access control models. With JIT, users don’t carry admin or privileged roles all day. Instead, they request access, get approvals, complete the task, and
OpenSSH 10.0: A Comprehensive Look at it’s Security-Driven Overhaul OpenSSH 10.0 released on April 9, 2025, marks a turning point for one of the most critical tools in modern IT infrastructure. As the de facto standard for secure remote administration, file transfer, and tunneling, OpenSSH has continuously evolved to address new threats and cryptographic trends.
Faillock is a security module within the PAM (Pluggable Authentication Modules) framework used in Linux systems. The pam_faillock.so module tracks failed login attempts from individual users over a defined time interval. The module automatically locks the user’s account when the number of failed attempts exceeds the configured threshold. This mechanism helps to protect Linux systems
ISO 27001 compliance is a globally recognized framework for managing and protecting sensitive information through a structured Information Security Management System (ISMS). ISO 27001 helps businesses identify vulnerabilities, implement effective security controls, and maintain regulatory compliance. Whether you’re pursuing ISO 27001 certification or strengthening your information security strategy, aligning with this standard boosts trust, credibility,
Managing SSH access to your Linux servers, routers, switches and other endpoint devices are paramount to maintaining security. This article describes how a security administrator can manage employees SSH access to Linux endpoint devices as a non-privileged system user, escalate the privileges and limit the commands that can be executed by the employee. We will describe below
