What is VoIP pen testing?

VoIP penetration testing is a type of penetration testing conducted on a company’s VoIP infrastructure. Pen testers simulate a realistic-looking cyberattack to find vulnerabilities and risks in VoIP systems and services and provide recommendation plans to remediate the risks.

Should I include VoIP phones in a pentest?

Yes, you should include voice-over IP phones in a pen test as they are also vulnerable to cyberattacks.

Is VoIP a security risk?

Just like any other internet-based digital device vulnerable to cybersecurity risks, VoIP systems and their components are also vulnerable, and hence, need protection.

Microminder’s VoIP Security Assessment Safeguards Your Communications

We at Microminder CS offer comprehensive voice-over IP security assessment services to detect, mitigate, and prevent security vulnerabilities and threats in your VoIP or cloud-based communication systems.

We thoroughly examine your complete VoIP setup, including network configurations, endpoints, and call servers. We also monitor your network traffic between the VoIP controller and handsets to identify weak points, fix them, and prevent attackers from exploiting them. This helps increase your cyber resilience.

Some of the threats we secure you from:

Also called call intercepting, eavesdropping is an act where a hacker intercepts VoIP calls to listen to the communication and steal information such as phone numbers, account names, passwords, etc. Leaving session initiation protocol (SIP) unencrypted can cause this.

In this threat, a hacker steals caller IDs from your VoIP network to impersonate an authorised or trusted personnel (for example, a senior manager). The hackers try to convince the receiver to expose sensitive data to launch an attack.

A hacker tries to disrupt active VoIP calls by delaying data packet delivery or overloading the path. This could destabilise communications.

Hackers flood the VoIP network with too many call requests to disrupt the VoIP service’s normal functioning, bringing chaos to the supply chain and business operations.

Hackers gain unauthorised access to a company’s VoIP systems to make costly, international or premium calls with the aim of gaining profits from the incurred charges. This leads the company to pay hefty phone bills and impacts other operations.

Spam over IP technology (SPIT) is a kind of phishing attack where a cyberattacker sends distorted, prerecorded voice messages to a company’s VoIP networks to clog the network, slow it down, and cause disruptions.

In voice-over misconfigured internet telephones (VOMIT) threats, a hacker converts a phone call into a file. The file can contain sensitive data, like financial details, private media, login credentials, etc. The hacker then transfers the file and uses it for malicious purposes.

Hackers use radio frequencies to gain access to VoIP systems and perform malicious activities by connecting their external phone line to your network. They change account details, control the system, and make costly phone calls to increase your bills.

Hackers dial too many phone numbers to detect and exploit devices with weaker access points.

Our VoIP security assessment experts will consult with your internal team

Microminders VoIP vulnerability assessment and penetration testing will monitor the network traffic transferred between handsets and the VoIP controller. We look for weak points that can be used by a malicious user to eavesdrop or inject malicious software.

Why Microminder

Our VoIP security assessment experts will consult with your internal team

These questions help us determine the level of security already in place and the potential threats facing your current VoIP phone system.

As we proceed to the actual testing phase, our VoIP security assessment experts will consult with your internal team tasked with managing your VoIP phone services. We need to determine:

Your exact VoIP environment
What other services your VoIP connects to within your network
What extra services your VoIP connects to via the internet

This knowledge will guide us during the testing phase to help rank the vulnerabilities we encounter in terms of risk.

Before we begin VoIP penetration testing, we need to answer some pertinent questions about your current VoIP provider to determine the current security level of your VoIP solution:

How Do We Perform VoIP Security Assessments?

Here’s the approach we follow to provide you with outstanding VoIP network security assessments and protect your business from attacks:

VoIP Security Audit:
Our expert security team conducts a comprehensive security audit of your current VoIP infrastructure using both manual and automated testing to find weak points. This includes examining your call servers, SIP and voice network traffic, network configurations, provisioning of endpoints and handsets, access controls, and encryption protocols. We find out whether these components align with security best practices or not. These insights help us define the scope of VoIP assessment.
Planning:
Once we’ve defined the scope and know the components with security vulnerabilities and risks, we start planning the penetration testing or VoIP security testing. We form the team, assign roles and responsibilities to them, and prepare scenarios for testing.

While preparing the penetration test scenarios, we ensure they’re based on the latest trends or recently discovered vulnerabilities to keep up with evolving threats. In addition, we’ll keep you informed of all the activities so you know what’s happening with your VoIP infrastructure.
VoIP Penetration Testing:
In the next phase, we conduct VoIP penetration testing simulating a real-world cyberattack based on the decided scenario. Our experienced and expert pen testers attack your VoIP infrastructure to find security vulnerabilities and risks. It can include assessing your VoIP systems for malware, viruses, traces of spoofing, DDoS attacks, call interception, and more.

Once our pen testers are successful in finding vulnerabilities, they try to exploit them and launch a cyber attack. It helps us assess how resilient your security measures are. In addition, we also evaluate your incident response and preparedness against cyberattacks.

How Do We Perform VoIP Security Assessments?

Analysis and Reporting:
After the VoIP test is complete, we analyse the results. We detect abnormal patterns that could point to a security breach, for instance, suspicious calls, abnormal surges in phone bills, signs of unauthorised access, and more.

In addition, we document all our findings and report them to your team. We list all the vulnerabilities and risks we discovered through the pen test, how your team handled the crisis, how robust was your security posture, and other details.
Monitoring and Optimisation:
We at Microminder CS encourage healthy discussions between your team and ours regarding the penetration test and solving highlighted issues. We together create an action plan to mitigate threats and future-proof your VoIP systems.

Our security team using their years of expertise recommends possible solutions to address risks and optimise your VoIP cybersecurity. We also continuously monitor your VoIP infrastructure using advanced real-time monitoring solutions to detect and neutralise threats as they occur, offering comprehensive, around-the-clock VoIP security.

In addition, we ensure your VoIP systems are aligned with security best practices and adhere to regulatory compliance requirements, such as UK GDPR, HIPAA, etc., avoiding possible penalties and reputation damage.
