Is VoIP Secure? VoIP Best Security Practices

VoIP is an acronym for Voice over Internet Protocol that describes how to place and receive phone calls via the internet instead of traditional landline phones. Most people consider VoIP as a cheaper alternative than using your local telephone company.

VoIP is the newest and best way to make phone calls. VoIP offers many benefits that traditional analog phones do not, such as placing long-distance or international calls with a simple click of your mouse anywhere in the world where there’s an internet connection!  

How Secure Is VoIP?

VoIP can provide a cheaper way to call internationally. However, because it is on the internet and not over traditional phone lines, some VoIP security concerns need addressing before you start using VoIP for all your calls. VoIP phone systems have inherent network security concerns. With the cost savings and functions, business leaders need to know that their VoIP system is resilient to new and frightening threats that are discovered on a daily basis.

Security is essential to every business. The business scale doesn’t matter; whether if you have a large organization or a small business owner; a disruption to your phone system would be nothing short of catastrophic and VoIP networks are no different from any other communications systems, as they can also fall victim to a malicious attack on the network or digitally-based security breach by hackers –whatever it may be!

Cybersecurity Risks of Using a VoIP Phone

The VoIP security landscape is complex, so you’ll want to stay vigilant. Here’s a breakdown of the types of security risks that are out there:

Denial of Service (DoS)

A denial of service attack can have a big impact on call centres by disrupting and dropping phone calls. A network that is starved for resources will be much more likely to experience these problems, which are bad news for those who rely on functional phones in their business dealings.

War Dialing

Perhaps the most ingenious way to hack someone’s work phone is war dialling, which involves controlling your PBX and scanning through other networks.

Toll fraud

Toll fraud is quite the same as war dialling. It requires access to make calls from your phone system, and attackers can use it for international calling that racks up charges to thousands of dollars.

Call interception

Attackers use unsecured networks to intercept session initiation protocols that are not effectively encrypted. This could include voice calls and video calls.

Malware

Many a company has fallen to this malicious software or malicious code attack. The malware can be used through phone or email. It will leave you susceptible to infiltration from attackers who want your business data!

Phishing

Phishing is the act of sending an email, text message, or other communication that appears to come from a trusted source to trick someone into revealing personal information. One common type of phishing scam is for attackers to send messages with caller ID spoofing, so it looks like they are calling from your business phone number. Attackers will then ask you for sensitive data such as your password or IP addresses, and other network details. Once they have this info, they can access all aspects of your business – including customer records, credit card details, financial transactions, and more.

Best Practices to Make VoIP Service Secure

Although a VoIP service provider and internet service providers would offer security policies, it is best to avoid leaving your business network vulnerable. Keep your business communication system safe with an additional layer of security.

Use a strong password

To keep your VoIP system secure, it is essential to have a strong password. Most businesses enforce a strong password policy as a layer of security. Encourage employees to immediately change the default password and use a combination of letters and numbers and special characters like the dollar sign or asterisk on top of other symbols to create a unique passphrase that can’t be easily guessed by others. Discourage employees from saving their passwords or passphrases digitally on their devices. This can cause VoIP security issues and is considered a major network security risk.

Encryption

Encryption is a great way to keep secrets safe. Encrypt the data using several methods to protect against hackers and other malicious attacks, which will be very useful if you have clients with sensitive or damaging information that needs protection on your network.

Make sure you update your operating system

Apply operating system updates often! You know that taking the time to install a few small patches every now and then is always good practice. It’s especially important for you as an administrator of your company or school’s computer network since these can guard against malicious software and other exploits.

Set up a VPN connection for remote staff

VPN is a virtual private network that encrypts all your data. It’s perfect for remote workers that operate outside the office or work from home. This helps to avoid the risk of being hacked, snooped on, or otherwise targeted by cybercriminals so they can safely do their job without interruption. Recently there was some research done in this field that showed that after installing a VPN, VoIP call quality didn’t deteriorate as much as we might have thought before!

Deactivate inactive VoIP accounts

Don’t let inactive employees disrupt the workplace. If you notice an employee has left, ask your IT staff to deactivate their accounts promptly! Aside from VoIP not working without a user assigned to it, there is no reason for unused accounts to be taking up space in your company database or email system.

Education

Educate people on online security risks and how not to get hacked. Explain that you don’t need their passwords and teach them what phishing is, so they know when someone might be trying to scam them into giving up personal information. Make sure everyone knows who the contact person for VoIP security issues are in case something happens where it’s needed!

Encourage your staff to report unusual behaviour. Ask your team if they have been experiencing any strange occurrences, such as missing voicemails or ghost calls. A “ghost call” is when your phone rings without a caller on the other end of the line; experts recommend erasing messages after only 30 days at most to avoid this occurrence from happening more often.

Remote Device Management

Implement remote device management. When it comes to your enterprise, having the ability to wipe a mobile device remotely is an absolute must. Issue laptops or cell phones with this capability so you can track and erase devices in case of theft or compromise.

Final Thoughts

Executives need to be mindful of their online safety. By following these best practices, there is less chance that your company can fall victim to an attack.
