Cyberattacks are a significant threat to the telecom industry, which is vulnerable due to sensitive customer data and evolving technologies. Traditional methods like penetration testing and vulnerability scans have limitations, highlighting the need for continuous, automated security monitoring. Breach and Attack Simulation (BAS) emerges as a solution, offering a comprehensive approach by simulating real attacks to validate security effectiveness and prioritize threats.

- 1. Cyberattacks pose a clear and present danger to businesses large and small. And the telecom industry – with huge amount of sensitive customer data, and critical business nature – offers adversaries rich pickings. Threat landscape is always increasing as traditional telecom networks transform into smart, application and service-aware, high speed and low latency infrastructure, which adopts a lot of new technologies. Suffice to say, a lot of mobiles networks remain extremely vulnerable to sophisticated attacks. Telecom security leaders have predominantly used two means to assess the security of their core network and data systems: Penetration-testing, and Vulnerability scans. These techniques primarily help assess the health and strength of the security systems at large and have an important role to play. However, these approaches come with their own set of limitations. Telecom Network Security Assessment: Legacy versus BAS (Breach and Attack Simulation) security approach
- 2. The strength of a vulnerability scanner is its automated approach to security monitoring. On the flip side, this means it can only detect known/potential vulnerabilities, providing no information about context and real environment – leaving the main question unanswered – “is it exploitable or not?” Similarly, while Penetration testing offers a more customized and thorough examination: if it is possible to infiltrate into the system and introduce negative impact, its manual and cost-heavy approach leads to infrequent assessments. Not only does this limit the coverage, but it also adds to the cost overheads. Given the ever-growing and complex nature of telco ecosystems, automated and continuous monitoring of systems is the need of the hour. Apart from validating the efficacy of the systems, a detailed prioritization and remediation guidance could be really helpful. It is essential to have an intelligent solution that helps classify business-critical systems, identify threats and further help prioritize them, based on set parameters, to ensure enhanced security. This is precisely where BAS emerges as the perfect fit for telecoms. By simulating real-life attack scenarios, it helps validate the efficacy of your security systems while the automated format and remediation module helps save on the resource overheads and strengthen the security posture.
- 3. Let's look at how each of these systems work, and the limitations of each approach. Limitations: An automated tool scans the systems to detect known weaknesses within the environment. The idea is to discover vulnerabilities by running tools against a target system, application, or network, and generate a report listing these vulnerabilities. Vulnerability Scanner: It only lists the vulnerabilities based on knowledgebase, with no insights into the real risks posed to the business It helps to collect data but doesn't provide analysis about how a particular vulnerability could be exploited It can only detect known vulnerabilities, which leaves the whole zero-day vector open for exploitation It may generate false-positive alerts, which then need to be assessed by the security teams It continuously tests and detects the environment, but lacks scope and threat ˜ˡ˦˜˚˛˧˦˲ It doesn't provide any context-aware remediation guidance It can only notify about the presence of a vulnerability, but is not capable of checking for effects in case of an exploit It Involves installation cost and requires skilled resources A pen test is a semi-manual test conducted by a team of penetration testers, or ethical hackers, and is used to identify and verify networks and identify entry points and threats within an environment. During the pen testing exercise, the testing team carries out cyberattacks to assess the strength of your security system against potential vulnerabilities. Pen-testing also has its limitations.

- 4. The new entrant in the telecom industry stands out because it provides comprehensive security coverage by overcoming the limitations of the legacy testing approaches mentioned above (Pen-testing and Vulnerability scanners). The BAS solution helps identify the landscape by collecting basic information about existing assets and vulnerabilities on network nodes. Then, by performing a simulation of real attack scenarios, it assesses whether the vulnerabilities are real and can be potentially exploited. Moreover, it generates an automated, easy-to-read security posture report at the end of each assessment, covering details of severity level, description of threats identified, and guidance on how to fix the threat/s.
