Strengthening Linux Server Security: OpenSCAP, Lynis, AIDE, SELinux, Fail2ban, Firewalld, and FIPS Mode

Strengthening Linux Server Security: OpenSCAP, Lynis, AIDE, SELinux, Fail2ban, Firewalld, and FIPS Mode Securing your Linux server is crucial given the increasing number of cyber attacks against Linux systems. Linux offers many benefits as a stable and flexible server operating system, making it an ideal platform for hosting vital apps and sensitive information. To fortify your Linux server, we’ll discuss several open source tools and methods that can help you reinforce your defenses against potential threats. We recommend employing OpenSCAP, Lynis, AIDE, SELinux, Fail2ban, Firewalld, and enabling FIPS mode to optimize your system’s resistance to intrusions. OpenSCAP: Assessing and Auditing Server Security OpenSCAP is a free and open-source solution designed to evaluate the security posture of Linux servers based on SCAP (Security Content Automation Protocol) guidelines created by NIST (National Institute of Standards and Technology). By utilizing OpenSCAP, you can perform thorough vul...

Configure MariaDB and MySQL Galera Replication performance

Configure MariaDB and MySQL Galera Replication performance 1. File Modification     - Open the `/etc/mysql/mariadb.cnf` or `my.cnf` file (note that `my.cnf` is a soft link to `mariadb.cnf`).     - Add the following configuration options:     ```bash     # Provider specific configuration options     wsrep_provider_options="gcache.size=1024M;gmcast.segment=0;gcache.recover=yes"     # Number of threads to process writesets from other nodes (depends on total CPU of the host)     wsrep_slave_threads=8     ``` 2. Understanding gcache     - Galera uses a preallocated file called gcache to store writesets in a circular buffer style.     - The gcache size defines how many writesets the donor node can serve in Incremental State Transfer (IST).     - You can estimate the downtime you can afford while still being able to perform an IST ...

Enabling Brotli Compression for Improved Website Performance

Enabling Brotli Compression for Improved Website Performance Enabling Brotli compression on web servers (both Nginx and Apache) for improved website performance. We can check our web browsing is using Brotli Compression using this online tools. https://tools.keycdn.com/brotli-test and https://www.brotli.pro/ Brotli is a new open-source compression algorithm developed by Google that can significantly reduce file sizes compared to traditional methods like Gzip. This can lead to faster website loading times, improved user experience, and potentially lower bandwidth usage. Here are some benefits of Brotli compression: Reduced File Sizes: Studies show Brotli can achieve up to 26% better compression ratios compared to Gzip. Faster Loading Times: Smaller file sizes translate to faster downloads and quicker page loads for website visitors. Lower Bandwidth Usage: Reduced file sizes can lead to lower bandwidth consumption, which can be beneficial for users on limited data plans. Efficient CPU Us...
