Prevent Hackers from Stealing Your VoiP and Costing You Money
Best ways to prevent your business from losing money because of hackers stealing your VoIP service.
In 2017, telecom fraud amounted to $29.2 billion in losses to organizations and carriers, according to No Jitter. One form of telecom fraud is theft of service, which is obtaining service through an individual or company without payment. VoIP is much more prone to theft of service than traditional telephony services. Service can be stolen through hackers stealing user names, passwords, and other account information. Hackers also can introduce malware into the system to more easily enable theft. Unfortunately, the Federal Communications Commission has not issued any regulations on VoIP fraud, which means that businesses are still liable for any hacked calls. Fortunately, businesses can take some precautions to prevent theft.
When businesses buy a new phone, they should always change the password from the factory settings. Some phones use different passwords for the phone interface and web interface. In this case, unique passwords should be used for each interface. Passwords should be made secure by changing them every six months and requiring at least 12 characters including upper and lower case letters, symbols and numbers. Businesses also should regularly update the admin portal password for the VoIP provider.
Limit Physical Access
VoiP phones and other instruments should be kept in a locked space to prevent unauthorized access. The environment of the space should be maintained within the limits set by the equipment manufacturer. Secure access panels to the air conditioning and power.
Build Security in Layers
To prevent attacks and service theft, an organization should plan its VoIP system as carefully as it does its data network. One way is to plan security in layers.
- The first layer of security is preventing intrusions on the network. To secure the network, use VoIP-aware firewalls and shut down ports at any sign of malicious behavior, according to Tech Target.
- The second layer of security is phone authentication. The phone will not be authorized to the network or to the IP PBX unless a mutual certificate exchange or a certificate and dongle architecture have authenticated it, according to Tech Target.
- The third layer involves encryption or authentication between the media and various channels. This means media gateways, ALGs, firewalls and NAT devices, and SBCs, according to Tech Target.
- Finally, the fourth layer is user authentication. Only users authenticated via a user name and password or token device or mutual swap should be allowed to make or receive phone calls, according to Tech Target.
Disable International Calling
Most hackers go after the more expensive international phone numbers. Businesses that don’t need to regularly make international calls can disable international calling, using an international calling card when necessary. If regular international calling is required, businesses should carefully check invoices to be sure all calls made are legitimate.
is relatively easy to breach if extra precautions aren’t taken. They gain access to your email via simple tricks like getting you to share your password on a spoofed 365 website.
Deploy education and technology to both prevent someone hacking a CEO email and to quickly identify when you or someone in the company has been compromised. This might include:
- Powerful spam filters
- Monitoring software
- Malware protection and firewall
- Security awareness training
- Other customized solutions to maximize security

Tips to Protect Your Mac Computer from Cyber Threats
Mac computers have an excellent reputation when it comes to cybersecurity, but they can still be targeted. Find out about protecting your Mac from threats.
Malware, ransomware, phishing—the cyber threats on the internet abound, and these threats are generating an astounding cost to the people who rely on computer systems to do business. To date, the cost of cyber infections has racked up billions of dollars in costs to unwitting business owners, some of which thought they were protected. Even though Macintosh (Mac) computer systems are highly regarded for their security, they are still at risk. Here are a few tips you should know.
1. Keep your Mac properly updated.
Without a doubt, one of the biggest reasons Mac computers fall victim to a cyber-attack is because they are not updated as they are meant to be. The developers of the Mac operating systems, whether it is one of the older Mac OS versions or something more modern like Mojave, send out frequent security patches as new updates. If you have automatic updates turned off or do not take the time to update your computer manually, you could easily miss an important line of defense.
2. Use good security programs on your business Mac.
Just because you have a Mac that has a stellar reputation for protecting itself against cyber threats, it does not mean that you should not go a step further and install a good security program. These software programs are designed to catch all those things that get past the existing Mac firewalls and security defenses.
3. Keep your Mac free of unnecessary programs.
Every user has them—those unnecessary programs that are really not used often enough to be counted as valuable or useful. These unnecessary filler programs take up valuable space on your Mac computer and slow it down. If the system is already slow, it can make it harder to recognize when something is awry and something fishy is going on. Plus, the more unnecessary programs you have that you never use, the easier it is for malicious software to latch onto something and set up shop on your computer because you will never see it.
4. Get educated about the biggest threats to security on your Mac.
Knowledge is a powerful defense tactic no matter what type of computer or OS it is that you rely on as a business professional. You should take the time to familiarize yourself with the biggest MAC cyber threats and the types of cyberattacks most often occurring today. You should familiarize yourself with things like:
- Phishing and how phishing attacks are carried out as well as how to avoid them
- Ransomware and how it gets latched onto your Mac system
- How to avoid things like malware that get attached to legitimate software
Whether you use your Mac for everyday tasks and projects at work or you have a system of Mac computers utilized by multiple employees and users within your organization, it is critical to protect your business Mac computers properly. Work with a managed IT service company to implement the best security measures and negate Mac cyber threats.
