Linux Security Secrets: How to Secure the Server from Cyber Threats

#SecureLinux

Why Linux Server Security Matters?

Linux servers power much of the internet. Robust security prevents data breaches, downtime, and cyber threats targeting vulnerabilities.

#ProtectYourData

Keep Software Updated

Regularly update the OS and software packages using tools like apt or yum to patch vulnerabilities and enhance server protection.

Harden User Access Controls

Use strong passwords, enable two-factor authentication, and restrict root access with sudo to minimise unauthorised access risks.

#LockItDown

Configure Firewalls Effectively

Set up firewalld or iptables to control traffic. Allow only necessary ports and services to reduce attack surfaces.

#BlockIntruders

Implement Intrusion Detection Systems

Use tools like Fail2Ban or AIDE to monitor suspicious activity and detect unauthorised changes, ensuring proactive threat response.

#StayVigilant

Encrypt Data and Backups

Enable encryption for data at rest and in transit using tools like LUKS or SSL/TLS. Regularly back up data securely.
