Cloud Contact Center Security

 

Introduction

 

Customers communicate with organizations in a variety of forms—from phone conversations to email, web chat and social media. As each interaction may contain sensitive and confidential information, security has become a top requirement for consumers and enterprises alike.

 

Many companies are turning to cloud-based solutions for more robust security as part of their contact center strategy. Cloud contact center solutions provide many advantages over traditional on-premise solutions, including the lower upfront capital expenditure, deployment flexibility and scalability, relief of infrastructure installation and maintenance, and an instant gateway to advanced capabilities. One important benefit of cloud contact center solutions is the relief of security implementation. This built-in benefit—with the right cloud contact center solution—can translate into significant cost savings.

 

Mitel has implemented security measures that take a comprehensive multiple-layer approach that has been certified to meet industry’s standards including Payment Card Industry - Data Security Standards (PCI-DSS) and Health Insurance Portability and Accountability (HiPAA) compliance. In fact, Mitel has been providing secure cloud contact center solutions to leading enterprises, including some of the largest financial and insurance companies in the world, for over a decade.

 

Overview

 

Mitel’s security strategy provides controls at multiple levels of data storage, access, and transfer. The strategy includes the following components:

  • Physical Security

  • Network Security

  • Platform Security

  • Application Security

  • Data Security

  • Human Security

  • Compliance

Physical Security

 

Mitel’s MiContact Center Live Cloud solution for large enterprises operates in Tier 4-class data centers. Each data center employs the same physical security standards and is controlled by multiple security parameters including:

  • Electronic entry systems that require each person who enters a data center have a valid badge and pass biometric controls

  • System access includes multiple levels of authentication including two layers of biometric authentication

  • Surveillance cameras supported by infrared, ultrasonic and photoelectric motion sensors

  • Alarm systems deployed throughout the datacenters

  • Armed security guards on duty 24x7

  • Exterior walls constructed of steel reinforced poured concrete or reinforced masonry that exceeds building code requirements for structural strength

  • Multiple Internet connections to block intentional disruptions of service 

  • Multiple power connections with generator backup

  • Fire suppression systems

  • Tracking and recording of all access made to the data center

Network Security

 

MiContact Center Live uses network elements that interconnect systems and information across multiple locations. Mitel achieves network security through technical systems and processes including the following:

  • Firewalls: Multiple layers of firewalls are deployed

  • Web Application Firewall (WAF): Analyzes application level activity in real-time to detect and block malicious activity

  • Segmentation: Systems are broken up in logical groups with restricted access to other groups, helping to contain intrusions that may occur

  • Intrusion Detection Systems (IDS): Detects suspicious activity

  • Data Encryption: Ensures added security when data travels over our internal network and when customers access the information externally over other types of networks

SECURITY VULNERABILITY ASSESSMENTS

 

Mitel conducts internal and external network vulnerability scans each quarter (at a minimum) and after significant changes in the network (e.g. new system component installations, changes in network topology, firewall rule modifications, product upgrades).

 

As a result:

  • All potential vulnerabilities identified are communicated to appropriate Mitel personnel for remediation

  • All high-level vulnerabilities are scheduled to be corrected within 10 days 

  • Medium-level vulnerabilities are corrected and subject to Change Control Policy

  • Follow-up scans confirm compliance with Mitel security standards

In addition, the Mitel Security Operations Center (SOC) staff engages in efforts to monitor activities on the Mitel network 24x7x365. The SOC team manages the network to detect and prevent threats and to maintain recovery control and audit logs of all activities of all users. This allows the security team to assist any necessary investigations or audits.

 

Platform Security

 

As a cloud-based solution, MiContact Center Live was built as a multi-tenant solution with distributed systems on an application architecture to preserve the security of each tenant. Mitel has designed the platform with tight security in mind around servers and the operating system, middleware and application/ multi-tenancy stack.

 

HIGH AVAILABILITY

 

To minimize service interruption due to hardware failures, natural disasters, Denial of Service (DoS) attacks, or other catastrophes, Mitel has implemented a disaster recovery plans for its data centers. This program includes:

  • Geographically dispersed data centers that operate in activeactive mode.

  • Redundant applications that provide backup capabilities. If the primary server goes out of service, a backup server acts as the primary server.

LOAD DISTRIBUTION

 

MiContact Center Live deploys proxy and parallel servers to add efficiency to large-scale configurations. The use of these technologies reduces the loss of functionality and data caused by an outage or security attack.

 

MULTI-TENANT SECURITY

 

MiContact Center Live separates tenant applications and data. This isolation and separation preserves the integrity of each tenant environment and its data. Mitel supports the following tenant separations:

  • Server level: Each tenant has a unique and isolated (virtual or physical) environment with a single management system.

  • Data level: The application is designed so that access across tenants is securely administered.

Mitel may deploy different tenant separate methodologies depending on the features that a customer orders.

 

Application Security

 

Mitel has deployed the following application security methodologies:

 

SECURE BY DESIGN

  • Secure Software Installation Controls: Access to Mitel applications uses multi-level authentication and all access is logged.

  • Prudent Configuration of Access Controls: “Least Privilege” and “Need-to-Know” principles are applied during the design of the applications.

HOLISTIC SECURITY

 

Users access the MiContact Center Live Platform in the Cloud via our Secure Sign-in feature. Customers can adjust their level of password strength and expiration policies to fit their needs. The platform provides a rolebased and IP-based permission systems, giving you fine grained control over who in your organization has to access to specific applications and data. In addition, we offer several unique capabilities to ensure that your customers’ data remains secure. Mitel’s Secure Exchange feature, for example, allows callers to securely provide sensitive personal information while ensuring that agents do not hear or have access to that data.
