VoIP enables voice calls through the internet, replacing traditional phone lines for communication. VoIP system can offer significant benefits for educational organisations, such as lower costs, increased flexibility, and enhanced features. However, VoIP also introduces some security challenges that need to be addressed to ensure the privacy and integrity of your communications. In this article, we will discuss some essential VoIP security measures that educational organisations should implement to ensure a safe virtual environment.
Few VoIP Security Issues can Occur in Educational Organisations
Some of the common VoIP security issues for educational organisations are:
1. Toll fraud
This is when an attacker gains unauthorised access to your VoIP phone system and makes expensive long-distance or international calls at your expense. Toll fraud can result in significant financial losses and damage your reputation.
2. Denial-of-service (DoS)
This is when an attacker floods your VoIP phone system with excessive traffic or requests, overwhelming its resources and preventing legitimate calls from being made or received. DoS attacks can disrupt your communication services and cause downtime or loss of productivity.
This is when an unauthorised party intercepts and listens to your VoIP calls, potentially compromising sensitive information such as personal data, academic records, or financial transactions. Eavesdropping can also be used to perform identity theft, blackmail, or espionage.
This is when an attacker impersonates a legitimate caller ID or phone number to trick you into answering a call or disclosing information. Spoofing can also be used to bypass authentication or authorisation mechanisms on your VoIP system.
This is a form of phishing that uses voice calls to deceive you into providing personal or financial information, or performing actions that benefit the attacker. Vishing can leverage spoofing techniques to appear more convincing.
Best VoIP Security Measures to Minimize the Risks
To protect your VoIP phone system from these security risks, you need to implement some security measures and best practices, such as:
1. Use strong passwords
VoIP phones require a default password during setup, often simple, prompting users to change it. You should change this password to a strong and unique one that is hard to guess or crack. You should also change your passwords regularly and avoid using the same password for different accounts or devices.
2. Implement a firewall
A firewall is a device or software that filters the incoming and outgoing traffic on your network and blocks any unwanted or malicious packets. A firewall can help you prevent DoS attacks, spoofing, and other intrusions on your VoIP phone system. You should configure your firewall according to your VoIP provider’s recommendations and test it regularly for functionality and performance.
3. Monitor your call logs
You should review your call logs periodically to detect any suspicious or unusual activity on your VoIP phone system, such as unauthorised calls, high call volumes, or abnormal call durations. You should also report any incidents or anomalies to your VoIP provider or IT department.
4. Require remote employees to use a VPN
If you have employees who work remotely or use mobile devices to access your VoIP system, you should require them to use a virtual private network (VPN) to encrypt their traffic and prevent eavesdropping or interception. A VPN will also help you maintain compliance with data protection regulations.
5. Update your system regularly
You should keep your VoIP software and hardware up to date with the latest patches and updates from the vendor. This will help you fix any vulnerabilities or bugs that could be exploited by attackers.
6. Encrypt your traffic
Encryption is a process that scrambles the data in your VoIP calls so that only the intended recipient can decode it. Encryption can help you protect your privacy and confidentiality from eavesdropping or interception. You should use encryption protocols such as Secure Real-time Transport Protocol (SRTP) or Transport Layer Security (TLS) for your VoIP calls. You should also verify the identity and authenticity of your callers using certificates or digital signatures.
7. Choose a Secure VoIP provider
Not all VoIP providers are created equal when it comes to security. You should choose a reputable and reliable VoIP provider for your educational institution that offers high-quality service and support, as well as robust security features and solutions. You should also review their security policies and practices, such as how they handle data storage, backup, recovery, encryption, authentication, authorisation, monitoring, auditing, and incident response.

8. Educate your team
You should train your staff and students on how to use your VoIP system securely and responsibly. You should also inform them about the common VoIP security threats and how to avoid them, such as not answering calls from unknown numbers, not providing personal or financial information over the phone, and not clicking on links or attachments in unsolicited emails.
In a nutshell
In a nutshell, educational organisations adopting VoIP technology can bring numerous benefits, but it also introduces specific security risks. By implementing strong security measures, including using strong passwords, firewalls, encryption, and selecting a reputable VoIP provider like Wavetel Business, educational institutions can create a safe and reliable virtual environment. Additionally, educating staff and students about common threats is essential in maintaining a secure VoIP system.
