System administration and operations -hardware

Fujitsu-Siemens machine• Intel Xeon Quad Core 3 GHz, 4 GB RAM

Internet Connection:• 8 Mbps Wireless Connection and 20 Mbps Metropolitan optic

fiber connections

Security Access• the Internet packages are policy-routed to the PIX Firewall• root access - only through one front-end DMZ server and one IP• external access - Cisco VPN Client, installed on PIX Firewall.


Development and testing

• We are using a test system that contains replica of our website.

• Hardware is similar, so we can test scalability and the result of development work.

• Control version distribution: SVN

• We are using PHP Editor/Maker as IDE

• Quality assurance: External auditor


Future Website

• Redesigning of our homepage graphics • AJAX controls• Helpdesk and CRM integration• Call Center integrated solution• RSS Feed• GeoIP function• Improvement of Search Engine Optimization for Google• SMS integration for our customers• Alert functions for weather warnings

• To solve the security problems:• Web server vulnerability was tested through Internal and External

Security Audit.• The parameters used by the site scripts were identified and it was

applied on them a white listing policy.• Security bugs removed.

• Reconfiguring the web server included: • a new hardware and operating system: SUSE Linux • the latest versions of PHP, Apache, MySQL and security software

packages
