Manager-system

Our company works as a business process outsourcing (BPO) and software development organisation and certified ISO 270001 company. Current setup is 350 users, including development and BPO. Where we required a greater amount of security, we have migrated more than 300 machines to Red Hat Enterprise Linux®. Following are the areas where we have saved a lot of cost and achieved greater security:

• Our external firewall is on Linux using IPTables. It supports two lease lines.

• A Linux machine working as an internal router separates dev and BPO networks.

• Postgres is the database backend for our BPO application.

• Samba is used as the domain controller.

• LDAP is used for centralized authentication.

• Qmail is used as the mail server authenticating to LDAP.

• Squid is the proxy server authenticating to LDAP.

• CVS is the repository for code authenticating to LDAP.

• Horde is the web-frontend for mail and CVS.

• OpenOffice is used for documentation purposes.

• Nagios is used for monitoring server availability.
