VOIP security risks

According to a study by IBM, human error is the main cause of 95% of cyber security breaches.

Even companies that take all of the necessary security measures possible still face VoIP security risks because of human mistakes.

We explain how human error leads to cyber security breaches and what measures and policies your company can implement to reduce the risk.

How does human error lead to cyber security breaches?

Human error can be categorised into skill-based and decision-based errors.

Skill-based errors: occur during routine activities as a result of a memory lapse or being distracted. Skilled and experienced people are more susceptible to this type of error as tasks are performed with less concentration.

Decision-based errors: a result of the wrong decision being made, often because of a lack of knowledge or not having enough information to make an informed decision.

Regardless of the type of human error, effective cybersecurity training will reduce the number of mistakes made by employees.  

VoIP security risks faced by your company

Human error can compromise your business’ security in several ways, including:

VoIP phishing: cybercriminals are targeting VoIP systems via phishing methods to obtain sensitive information about your employees or company. The criminal will phone you and pretend to be from a reputable company and request confidential information. Personal details that the cybercriminal may already have about you will be used to try and lull you into a false sense of security.

Viruses and malware: VoIP security risks include viruses, worms and malware, just like all internet applications. Malware can be sent via attachments or links that can spread across your phone system, shutting it down.

Call tampering: an attacker tampers with a call in progress by injecting noise into the communication channel. The purpose of call tampering is to take over your phones and gain access to confidential information.

Denial of Service (DoS) attacks: a DoS attack is designed to shut down your VoIP system by flooding it with traffic or sending information that will trigger a crash. Once users are shut out, cybercriminals try to access sensitive information via the system.

Policies to put in place to avoid human mistakes

Reduce cybersecurity issues caused by human error by implementing these policies across your company:

A password management policy

A password management policy is a crucial part of cybersecurity for all businesses. It provides guidance on how to create and use strong passwords, minimising cyber-attacks. Here are some top tips on what you should include in your policy as a minimum:

  •  Determine what makes a strong password, for example, minimum 8-12 characters, a mix of lower and upper case letters, numbers and special characters.
  • How often passwords should be changed.
  • A reminder not to discuss passwords with anyone.

An effective password management policy is updated regularly, keeping in mind the latest trends and technology advancements.

A video conferencing policy

A video conferencing policy will allow your company to set clear boundaries for employees to help protect your company and staff. Guidelines should include:

  • Clear rules on not using personal phones for calls or video conferencing.
  • Not sharing sensitive information during calls.
  • Turning cameras and microphones off when not in use.
  • Only recording video conferences if everyone in the meeting gives their permission.

Cybersecurity training

If employees don’t know how to recognise VoIP security risks, how can they help prevent it or know how to report it?

Reduce human error with regular, effective cybersecurity training for all employees that covers:

  • Different types of cybersecurity threats such as phishing, ransomware, malware and social engineering.
  • The importance of protecting company data and sensitive information.
  • How to identify and report cybersecurity threats.

Cybersecurity training should be made mandatory for all new employees and refresher training should be provided for all employees regularly.

Corporate security policy

Your security policy needs to clearly cover the following:

  • How to handle critical data.
  • Who can access sensitive information.
  • Which security and monitoring software to use.
  • How to secure information physically.
  • Reporting requirements.

Regularly revising your security rules will ensure your company is in line with the latest advice and best practice techniques to keep your employees and data safe.
