How to Secure any Linux Server | Automated Server Hardening script

There are many open source developers who want to show their skills by developing web applications. Every developer tries to show something new. Or some developers try to automate their tasks. According to ethical hacking researcher of international institute of cyber security there are many phases from developing web application to deploying it. But in developing any web application, infrastructure security which should always considered on top priority. Every developer verifies the external attacks on their application. But in development phase everything should be done securely. Web applications should be developed securely. We will show an script which is use to secure any linux server or local web servers or hardening linux server in which developers will be deploying their website.

LAMP

LAMP is an open source utility used for creating web applications. Lamp is also specified as Lamp stack because it consists of four layers.

Lamp stands for (Linux, Apache, MySQL and PHP). Many developers used LAMP to develop & deploy web application. JShielder is used to secure Linux servers in which developers want to deploy their web applications. Jshielder automates the process of installing required packages to host web applications. In other words JShielder act as a Server Hardening (Server Hardening is a process to enhance server security) Some common tips of server hardening includes :-

  • Data Encryption for communication.
  • Changes protocols which sends important information in plain text.
  • Closes unnecessary services running on server.
  • Keep OS up to date, specially the security patches & malware removal tools.
  • Regularly update security policies.
  • Maintains & regularly checks the server logs.

JShielder Requires following configuration:-

  • Configures a Hostname
  • Reconfigures the Timezone
  • Updates the entire System
  • Creates a New Admin user so you can manage your server safely without the need of doing remote connections with root.
  • Helps user Generate Secure RSA Keys, so that remote access to your server is done exclusive from your local pc and no Conventional password
  • Configures, Optimize and secures the SSH Server (Some Settings Following CIS Benchmark)
  • Configures IPTABLES Rules to protect the server from common attacks
    Disables unused FileSystems and Network protocols
  • Protects the server against Brute Force attacks by installing a configuring fail2ban
  • Installs and Configure Artillery as a Honeypot, Monitoring, Blocking and Alerting tool
  • Installs PortSentry
  • Install, configure, and optimize MySQL
  • Install the Apache Web Server
  • Install, configure and secure PHP
  • Secure Apache via configuration file and with installation of the Modules ModSecurity, ModEvasive, Qos and SpamHaus
  • Secures NginX with the Installation of ModSecurity NginX module
    Installs RootKit Hunter
  • Secures Root Home and Grub Configuration Files
  • Installs Unhide to help Detect Malicious Hidden Processes
  • Installs Tiger, A Security Auditing and Intrusion Prevention system
  • Restrict Access to Apache Config Files
  • Disables Compilers
  • Creates Daily Cron job for System Updates
  • Kernel Hardening via sysctl configuration File (Tweaked)
    /tmp Directory Hardening
  • PSAD IDS installation
  • Enables Process Accounting
  • Enables Unattended Upgrades MOTD and Banners for Unauthorized access
  • Disables USB Support for Improved Security (Optional)
  • Configures a Restrictive Default UMASK
  • Configures and enables Auditd
  • Configures Auditd rules following CIS Benchmark
  • Sysstat install
  • ArpWatch install
  • Additional Hardening steps following CIS Benchmark Secures Cron
  • Automates the process of setting a GRUB Bootloader Password
    Secures Boot Settings
  • Sets Secure File Permissions for Critical System Files

According to ethical hacking researcher of International Institute of Cyber Security, all the above points are required by network administrators to secure their servers.

JShielder Installation ;-

  • For testing we will use Ubuntu 18.04 LTS. Before using JShielder LAMP must installed & configured in your Linux system. LAMP is just XAMPP which mostly used on Windows OS.
  • For installing LAMP open terminal type sudo apt-get update && For installing mysql type sudo apt- get install mysql-server mysql-client

 Connecting to MySQL using a blank password.\

 VALIDATE PASSWORD PLUGIN can be used to test passwords
 and improve security. It checks the strength of password
 and allows the users to set only those passwords which are
 secure enough. Would you like to setup VALIDATE PASSWORD plugin?

 Press y|Y for Yes, any other key for No:y
  • Choose the password policy. Enter 1
There are three levels of password validation policy:
 LOW    Length >= 8
 MEDIUM Length >= 8, numeric, mixed case, and special characters
 STRONG Length >= 8, numeric, mixed case, special characters and dictionary                  file
 Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 1

New password:

Re-enter new password:

Estimated strength of the password: 100
 Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) :y
  • Enter y & remove the anonymous user for enhancing security of the mysql. This will restrict anonymous login into mysql. As per Digital forensics expert of iicybersecurity, some DB Admin leave anonymous login, which further helps in attacks.
 By default, a MySQL installation has an anonymous user,
 allowing anyone to log into MySQL without having to have
 a user account created for them. This is intended only for
 testing, and to make the installation go a bit smoother.
 You should remove them before moving into a production
 environment.
 Remove anonymous users? (Press y|Y for Yes, any other key for No) :y
  • This depends totally on requirement whether to give remote root access or not. So we will enter n
 Normally, root should only be allowed to connect from
 'localhost'. This ensures that someone cannot guess at
 the root password from the network.
 Disallow root login remotely? (Press y|Y for Yes, any other key for No): n 
  • Remove the test user which comes by default in mysql. Enter y
By default, MySQL comes with a database named 'test' that
 anyone can access. This is also intended only for testing,
 and should be removed before moving into a production
 environment.
 Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y

 Dropping test database…
 Success.

 Removing privileges on test database…
 Success. 

 Reloading the privilege tables will ensure that all changes
 made so far will take effect immediately.
 Reload privilege tables now? (Press y|Y for Yes, any other key for No) :y

Success.
