Phyzer implements a set off comprehensive measures and procedures to ensure business
continuity and reliability.
A dedicated IT department is responsible for Infrastructure Engineering, Infrastructure
Change and Release Management. Responsible people are informed about all significant
events concerning the functioning of the information infrastructure on the 24x7
basis by using mobile phones with Email2SMS service enabled.
We have more than 300 Intel P4 (Core 2 Duo) and Apple Macintosh workstations and
30 servers in our four datacenters located in Minsk. All our datacenters are equipped
with efficient air conditioning, fire protection and UPS power protection systems.
Each server is built on the RAID technology (Level 1 or Level 5 controllers are
used).
Reliable Internet connection is provided via two independent data links with the
bandwidth of 4 and 1 Mbps. The connection between the datacenters is provided via
fiber-optic links with the bandwidth of 1Gbps. Reliability of power supply is ensured
by the presence of 3 separate and independent power feeders at every datacenter
and by the usage of high-performance UPSes. Internal information infrastructure
includes 20 HP ProCurve switches, 1 Cisco router and a set of telephony equipment
(hardware (Coral) and IP (Asterisk) telephone stations, 200 telephones and 5 GSM
gateways).
Failover capabilities are implemented for the main network services, such as Mail,
DNS, Internet Access, Active Directory and development servers. The Mail Server
backup is performed via two backup servers, one located in Europe and another –
in North America. This mechanism ensures that no incoming and outgoing mail is lost.
We have developed a number of documents covering our Security Policy: General Network
Usage Policy, Sensitive Information Encryption and Exchange Policies. General compliance
with our security policy and regulations is ensured by the usage of logon scripts
and Group Policies.
We perform careful security checks of every person that is applying for a job. Confidentiality
Agreements are an important part of the security system and every employee we hire
is to sign such an Agreement. All the security-related cases and incidents are tracked
and resolved by Department Managers. We inform all the people we hire about the
Company’s security standards and keep this knowledge up-to-date by organizing special
training programs on regular basis.
We imply a multi-level access control system. On the first level our security service
is checking our employee’s ID-badges to ensure they are authorized to access the
building. The next level of access control is based on the usage of electronic cards,
each possessing unique radio metrics, that are given to every employee that is authorized
to access the floors of our buildings. We have installed effective video monitoring
and alert systems in our offices and have arranged Governmental Security Service’s
(Police) protection of our property. The access control system is managed from one
central control point, though each datacenter’s security system is independent.
We understand that security of our client’s data in number one priority for our
business. We use 256 bit AES algorithm for traffic encryption and 2048 bit public/private
keys pair for authentication purposes. Sensitive data is exchanged via SFTP server
and PGP is used for emails encryption. This way compliance with the ISO standards
for information security is provided. We also strictly follow all the governmental
rules and regulations for emergency issues.
For development purposes we use virtualization technology which enables us to build
a separate operational environment for each project and thus increase resource allocation
flexibility and effectiveness. This technology is based on the usage of VMware Server
1.0, VMware ESX Server 3.0 and VMware Infrastructure for project monitoring.
All the processes are constantly monitored by the administrative team and vital
information on all the important changes and incidents is tracked and logged via
Syslog Server for future audit.
The Information Life Cycle Management (ILM) process we have developed at Phyzer
includes a set of data protection and other security-related activities. A special
data recovery scenario is presupposed for each kind of potential data loss situation
(e.g. hardware or software failure, computer virus, human mistake, etc.). The process
of backup copies creation is regulated by the Backup Process Plan.
Effective backup procedures are ensured by a number of physically distributed backup
locations Phyzer has in its offices in Minsk, dedicated servers in several countries
of the world and high level of encryption of backup data.
