Cloud Security: The Top 5 Factors for Secure Voice Services

How to / Guide

September 17, 2019

From easy integration to global scalability, UCaaS offers innumerable benefits for international companies hoping to improve their voice communications. However, many companies still have security concerns about migrating their communications to the cloud and allowing data to pass through the public internet. Undeniably, the nature of cloud communications has completely upended IT security, which is why it’s important to get updated on how to safeguard against vulnerabilities. If you’re ready to get started with the future of communication while also keeping your data secure, read our article for the top 5 security factors you should consider when migrating voice services to the cloud:

1. Secure Data Centres and SBCs

When looking for secure voice services, one of the first things companies should look into is how providers manage their data centres and SBCs. For example, it’s critical to make sure that available data centres have built-in redundancy, robust disaster recovery plans, and data centres that are global (not clustered) so that calls are not compromised because of natural disasters or other location-based emergencies. Similarly, since SBCs are often owned and managed by providers, companies should look into what partnerships providers have with SBC vendors and make sure that they provide necessary security features such as DoS protection. For added security, note that it is also recommended to have an SBC at each site.

2. End-to-End Encryption

When it comes to security, voice calls should be treated as a type of data, which is why it’s critical to implement end-to-end encryption and ensure that information is protected both in transit and at rest. This is especially important for organisations that must abide by regulations for user privacy, such as in healthcare, finance, and the public sector, as encryption helps to safeguard against eavesdropping attempts that could reveal sensitive information and even result in lawsuits. By supporting end-to-end encryption, companies can rest assured that data will be safeguarded at every point in the system.

3. 24/7 Global Support

No matter what security measures are in place, technology always carries risks. By having access to 24/7 global support, companies can take immediate action when preventive measures aren’t enough. This is especially important for cases of toll fraud, which occur when an intruder uses a corporate phone system to make costly international calls. This form of fraud is detrimental and costs companies billions of dollars a year – making it critical that support can be reached the moment an intrusion is suspected.

4. Authentication and User Access Controls

Companies should also use two-factor authentication for their accounts, which requires users to submit two different authentication factors to gain access to the network, which can include passwords, smart cards, security tokens, fingerprints, and even facial recognition technology. Additionally, organisations should implement robust user access controls with strong password requirements and automated password change policies. Companies should also train employees on the importance of using different passwords for each account and should promote individual sign-ins instead of single sign-on (SSO), which can easily compromise the network if a password is obtained.

5. Specialised Providers

Vendor experience can be crucial for ensuring that companies receive the right recommendations for voice-specific risks such as robocalling and call spoofing. Because of this, it’s helpful to work with a team that is specialised in voice, which allows companies to access services with more thorough protection and support than with other bundled solutions - especially for companies that require large-scale migrations. When using an experienced provider that understands the complex challenges that come with migrating to the cloud, companies can rest assured that their voice services will be secured with the data encryption, user controls, and support they need for secure voice communications, which might not be as easy to find with an all-in-one solution.
