Ubuntu Server Security Best Practices
Ubuntu Server is a highly sought-after, open-source operating system that serves as the backbone of many infrastructure setups across the globe. The efficiency and user-friendly nature of Ubuntu Server make it a go-to choice for organizations.
However, just like any other system, Ubuntu servers are susceptible to various security threats that can have devastating impacts on an organization's operations and data integrity. This article seeks to shed light on some of the best practices in securing an Ubuntu Server environment against common security threats. A holistic understanding of these practices is instrumental in building and maintaining a fortified digital frontier.
One of the first steps in securing your Ubuntu Server is proper user management. This involves:
- Creating a Separate Administrative User - Create a separate user with administrative privileges to carry out system administration tasks. This reduces the risks associated with using the root user for daily tasks.
- Implementing Strong Password Policies - Enforce strong password policies that require users to create complex passwords which are hard for attackers to guess.
- Utilizing SSH Key Authentication - Set up SSH key authentication for secure, password-less logins to your server. This not only enhances security but also simplifies the login process.
