What is a crucial requirement for sensor deployment regarding network connectivity?

The correct choice, which specifies that TLS 1.2 is required for sensor deployment, aligns with modern security protocols that ensure secure communications between the CrowdStrike sensors and the Falcon platform. TLS (Transport Layer Security) is integral for encrypting data transmitted across networks, and using TLS 1.2 provides improved security and resilience against various attack vectors compared to older versions.

TLS 1.2 introduces several enhancements over its predecessors, including better encryption algorithms and increased security against known vulnerabilities, making it a standard requirement for deploying the sensor effectively. This ensures that the data exchanged is protected against eavesdropping and tampering, which is essential for maintaining the integrity and confidentiality of the security operations being performed by the Falcon platform.

Using older protocols, such as TLS 1.0 or deprecated versions, would expose the deployment to potential security weaknesses that could be exploited by attackers. Meanwhile, TLS 1.3, while being more advanced, is not necessarily mandated for sensor deployment as of the stated knowledge cutoff and so is not the correct answer in this context. Hence, the focus on TLS 1.2 reflects an industry standard for secure communication at the time of the deployment requirement.
