DHCP

The DHCPD service is managed by the phpDHCPAdmin software. Two configuration file modifications are required.

/etc/conf.d/dhcpd

# /etc/conf.d/dhcpd: config file for /etc/init.d/dhcpd

# If you require more than one instance of dhcpd you can create symbolic
# links to dhcpd service like so
#   cd /etc/init.d
#   ln -s dhcpd dhcpd.foo
#   cd ../conf.d
#   cp dhcpd dhcpd.foo
# Now you can edit dhcpd.foo and specify a different configuration file.
# You'll also need to specify a pidfile in that dhcpd.conf file.
# See the pid-file-name option in the dhcpd.conf man page for details.

# If you wish to run dhcpd in a chroot, uncomment the following line
# DHCPD_CHROOT="/var/lib/dhcp/chroot"

# All file paths below are relative to the chroot.
# You can specify a different chroot directory but MAKE SURE it's empty.

# Specify a configuration file - the default is /etc/dhcp/dhcpd.conf
DHCPD_CONF="/var/www/tyr.example.com/phpDHCPAdmin/conf/dhcpd.conf"

/etc/init.d/dhcpd

Only the line that is to be modified to reflect the path to the leases file within the phpDHCPAdmin software

#local leasefile="$(get_var lease-file-name /var/lib/dhcp/${SVCNAME}.leases)"
local leasefile="$(get_var lease-file-name /var/www/tyr.example.com/phpDHCPAdmin/conf/${SVCNAME}.leases)"

BOOTP/TFTP

The BOOTP services relies heavily upon the Apache imaging.example.com CNAME DNS entry & VHOST configuration. The configuration file should reflect the path to the tftproot as being a part of the imaging.example.com VHOST root directory. See below:

# /etc/init.d/in.tftpd

# Path to server files from
# Depending on your application you may have to change this.
# This is commented out to force you to look at the file!
#INTFTPD_PATH="/var/tftp/"
#INTFTPD_PATH="/tftpboot/"
INTFTPD_PATH="/var/www/tyr.example.com/imaging/tftp"

# For more options, see in.tftpd(8)
# -R 4096:32767 solves problems with ARC firmware, and obsoletes
# the /proc/sys/net/ipv4/ip_local_port_range hack.
# -s causes $INTFTPD_PATH to be the root of the TFTP tree.
# -l is passed by the init script in addition to these options.
INTFTPD_OPTS="-R 4096:32767 -s ${INTFTPD_PATH}"

Apache

The current apache configuration requires modifications to several files. The default configuration options which get globally applied to all VHOSTS, the default system configuration file which indicate specific options to run apache with, and the VHOST configuration(s).

/etc/conf.d/apache2

Only the line which requires editing

APACHE2_OPTS="-D DEFAULT_VHOST -D CACHE -D MEM_CACHE -D INFO -D SSL -D SSL_DEFAULT_VHOST -D LANGUAGE -D PHP5 -D SECURITY"

/etc/apache2/modules.d/00_default_settings.conf

Only the lines which provide ACL for allowed subnets. This applies globally to all configured VHOSTS.

# We configure the "default" to be a very restrictive set of features.

        Options FollowSymLinks

MySQL

By default the MySQL service will only allow incoming connections on the local interface. This is a security pre-caution to prevent against unauthorized TCP port access outside of the currently running server. A combination of ACL's using TCPWrappers will help mitigate connects to the MySQL service as for the OmniPage campus service to have access to the softwaredb.example.com MySQL database binding MySQL to a public IP is necessary.

#bind-address                           = 127.0.0.1
bind-address                            = 192.168.17.166

Arpwatch

Because tyr is listening on all available staff, public, server & labs subnets this service can monitor for MAC hardware changes in regards to man in the middle attack scenarios of machines trying to spoof the default gateway per subnet.

# Config file for /etc/init.d/arpwatch
# see arpwatch.8 for more information

#IFACES="eth0 eth1"
#IFACES="eth0"
IFACES="vlan21 vlan22 vlan57 vlan61 vlan71 vlan81 vlan91 vlan101 vlan111 vlan121 vlan131 vlan141 vlan151 vlan171 vlan181 vlan461"

# Additional options to pass to arpwatch.
OPTIONS="-N -p"

# Comment this line if you wish arpwatch to run as root user (not recommended)

Policies

These policies pertain to system management. Please follow this guide to ensure steps are taken so that this server does NOT become a development testing ground for projects.

MySQL

When creating new accounts on the MySQL database there are a few things that should be addressed to eliminate unauthorized/un-necessary access to other database's etc. A strict set of permissions per account should be used to ensure one user account compromise does not lead to full and complete write access to the remainder of the database's.

New database

This portion should proceed any account creation to ensure proper permissions can be assigned to the new account(s)

mysql -u root -p -e "CREATE DATABASE dbname"

New user

Below are a few examples of creating new users with various levels of privilege on a per database basis. Please note that the remote user examples should be VERY limited as very seldom (IF AT ALL) should you allow a remote direct connection to the MySQL service.

local user creation

These should be used most frequently as any new web applications that require database access should be installed on this server as a VHOST (see Apache policy)

read only all tables

This example provides strict connection parameters as well as read only privileges for the specified user account to all tables on specified database

mysql -u root -p -e "CREATE USER dbUser@localhost IDENTIFIED BY 'dbPass'; GRANT SELECT, REFERENCES, INDEX ON dbName.* TO dbUser@dbHost; FLUSH PRIVILEGES"
read only specified table

This example provides strict connection parameters as well as read only privileges for the specified user account to a specified table on specified database (if multiple tables should be allowed read access for this user you must issue the 'GRANT SELECT' for each table)

mysql -u root -p -e "CREATE USER dbUser@localhost IDENTIFIED BY 'dbPass'; GRANT SELECT, REFERENCES, INDEX ON dbName.dbTable TO dbUser@dbHost; FLUSH PRIVILEGES"
write all tables

This example provides strict connection parameters as well as write, select, update, delete, execute privileges for the specified user account to all tables on specified database

mysql -u root -p -e "CREATE USER dbUser@localhost IDENTIFIED BY 'dbPass'; GRANT SELECT, INSERT, UPDATE, DELETE, REFERENCES, INDEX, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE ON ON dbName.* TO dbUser@dbHost; FLUSH PRIVILEGES"
write only specified table

This example provides strict connection parameters as well as write, select, update, delete, execute privileges for the specified user account to a specified table on specified database (if multiple tables should be allowed read access for this user you must issue the 'GRANT SELECT' for each table)

mysql -u root -p -e "CREATE USER dbUser@localhost IDENTIFIED BY 'dbPass'; GRANT SELECT, INSERT, UPDATE, DELETE, REFERENCES, INDEX, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE ON ON dbName.dbTable TO dbUser@dbHost; FLUSH PRIVILEGES"
Remote user creation

Here are examples (similar to above) where a remote connection may be used (per user & per database restrictions apply). Please note that these commands allow access from anywhere which is bad practice in terms of the 'deny all by default' methods. A better use of these commands is to restrict new account creation by subnet or specific IP ranges (see first example)

read only all tables from network
mysql -u root -p -e "CREATE USER [email protected].% IDENTIFIED BY 'dbPass'; GRANT SELECT, REFERENCES, INDEX ON dbName.* TO [email protected].%; FLUSH PRIVILEGES"
read only specified table from network
mysql -u root -p -e "CREATE USER [email protected].% IDENTIFIED BY 'dbPass'; GRANT SELECT, REFERENCES, INDEX ON dbName.dbTable TO [email protected].%; FLUSH PRIVILEGES"
write only from anywhere to all tables
mysql -u root -p -e "CREATE USER [email protected].% IDENTIFIED BY 'dbPass'; GRANT SELECT, INSERT, UPDATE, DELETE, REFERENCES, INDEX, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE ON ON dbName.* TO [email protected]%; FLUSH PRIVILEGES"
write only from network to specified table
mysql -u root -p -e "CREATE USER [email protected].% IDENTIFIED BY 'dbPass'; GRANT SELECT, INSERT, UPDATE, DELETE, REFERENCES, INDEX, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE ON ON dbName.dbTable TO [email protected].%; FLUSH PRIVILEGES"
read only all tables from anywhere
mysql -u root -p -e "CREATE USER dbUser@% IDENTIFIED BY 'dbPass'; GRANT SELECT, REFERENCES, INDEX ON dbName.* TO dbUser@%; FLUSH PRIVILEGES"
read only from anywhere to specified table
mysql -u root -p -e "CREATE USER dbUser@% IDENTIFIED BY 'dbPass'; GRANT SELECT, REFERENCES, INDEX ON dbName.dbTable TO dbUser@%; FLUSH PRIVILEGES"
write all tables from anywhere
mysql -u root -p -e "CREATE USER dbUser@% IDENTIFIED BY 'dbPass'; GRANT SELECT, INSERT, UPDATE, DELETE, REFERENCES, INDEX, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE ON ON dbName.* TO dbUser@%; FLUSH PRIVILEGES"
write only from anywhere to specified table
mysql -u root -p -e "CREATE USER dbUser@% IDENTIFIED BY 'dbPass'; GRANT SELECT, INSERT, UPDATE, DELETE, REFERENCES, INDEX, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE ON ON dbName.dbTable TO dbUser@%; FLUSH PRIVILEGES"

Apache

The old tyr.example.com used the default webserver root for everything. Despite my best efforts at implementing a process for new projects (requiring a vhost, associated database with restricted set of permissions etc) it got convoluted and hard to maintain quite quickly.

To disparage this practice from occurring again I have forced vhost's for each project and am now implementing a new policy that no new projects will go on this server without first being tested on a development server. New projects will be created with the following guidelines:

vhost

All new projects will use a vhost configuration within apache.
