Wardialing: Increase Telecommunication & Network Security with Proactive Testing

Updated: Jan 12, 2023

Page 1: Introduction to Wardialing Assessments


When it comes to computer security, proactive monitoring and assessment should be one of the primary activities your organization takes on. How safe or secure are your networks and systems from malicious outside interference? Wardialing assessments can help you answer that question and give you greater insight into how prepared you are for any malicious attacks that may come your way.


Wardialing is the process of scanning a network to uncover which telephone numbers are actively connected and in use. The process is used to detect any vulnerable points in the system that could be used to break into the network. It’s a proactive approach to cybersecurity that checks for any backdoors or other points of access that can be taken advantage of. With this in mind, it’s important to understand how to conduct wardialing assessments and how they can be beneficial to your network security plan.

Developing a wardialing assessment plan is the first step in protecting your network from potential malicious attacks. Your plan should include which system components should be tested, the methods for detection, a timeline for scanning, any precautions taken against false positives, and a strategy for dealing with any vulnerable points.


It is important to have a well-thought-out plan in place, as this will ensure that your network security is properly tested and monitored. Depending on the size and complexity of your network, the plan should include detailed steps for both passive and active scanning.

Passive scanning is the first type of assessment that can be conducted during a wardialing assessment. This involves monitoring all incoming and outgoing calls to and from your network. By analyzing the traffic, any suspicious activity can be identified before it has a chance to cause damage.


It’s important to note that passive scanning can take a while as it requires manually reviewing all traffic. As such, it is best to use passive scanning along with active scanning to ensure a complete assessment.

Active scanning is the second type of assessment that can be conducted during a wardialing assessment. This involves using automated tools to scan the network and analyze any potential vulnerabilities.


Active scanning allows you to quickly identify any potential threats, as well as identify any potential backdoors that can be taken advantage of. Automated tools can also scan for any areas of weakness in the system, such as easily guessable passwords or weak encryption protocols.

Conducting a wardialing assessment provides many benefits to network security. It is a proactive approach that allows you to identify any vulnerabilities before they are discovered by malicious actors. It also helps you understand the overall health of your network, which can be beneficial when making any security-related decisions.


By conducting regular wardialing assessments, you can ensure that your network is up to date and secure. Additionally, wardialing assessments can also help you detect any suspicious activity that could be indicative of malicious activity.

Wardialing assessments are an important tool for network security. By proactively monitoring your network, you can ensure that it is secure and free from any malicious actors. With a well-thought-out plan in place, you can conduct both passive and active scanning to identify any potential threats.


Wardialing assessments provide many benefits, including increased security and peace of mind. With regular assessments, you can ensure that your network is up to date and secure, as well as identify any suspicious activity that could be indicative of a malicious attack.
