mysql-hardening (Chef cookbook)

Description

Provides security configurations for mysql.

Note: This is currently work in progress and not tested on all supported platforms

Requirements

  • Opscode chef

Usage

This cookbook is optimized to work with os-hardening and ssh-hardening. It will play well without, but you need to ensure all preconditions like apt-get update or yum update are met.

Security Options

Further information is already available at Deutsche Telekom (German) and Symantec

Security Configuration

This setup sets the following parameters by default

user = mysql
port = 3306
bind-address = X.Y.Z.W

# via ['mysql']['security']['local_infile']
local-infile = 0

# via ['mysql']['security']['safe_user_create']
safe-user-create = 1

# via ['mysql']['security']['secure_auth']
secure-auth = 1

# via ['mysql']['security']['skip_show_database']
skip-show-database

# via ['mysql']['security']['skip_symbolic_links']
skip-symbolic-links

# via ['mysql']['security']['automatic_sp_privileges']
automatic_sp_privileges = 0

# via ['mysql']['security']['secure-file-priv']
secure-file-priv = /tmp

Additionally it ensures that the following parameters are not set

  • deactivate old-passwords via ['mysql']['security']['secure_auth']
  • deactivate allow-suspicious-udfs via node['mysql']['security']['allow-suspicious-udfs']
  • skip-grant-tables
  • chroot (instead we prefer AppArmor for Ubuntu)

Furthermore the permission of /var/lib/mysql is limited to mysql user.
