Patching helps to mitigate vulnerabilities by applying fixes or updates to software or firmware that have known security flaws. Vulnerabilities can be exploited by cybercriminals to compromise the confidentiality, integrity, or availability of the IT systems and data. Patching endpoints consistently reduces the risk of cyberattacks and data breaches by closing the gaps that attackers can use to gain unauthorized access or cause damage. Patching also improves the performance and functionality of the IT systems by addressing bugs or errors12.
Option B is the correct answer, as it explains the main benefit of patching endpoints consistently. Option A is incorrect, as patching does not necessarily reduce the attack surface of the infrastructure, which is the total number of possible entry points for an attacker. Patching only addresses the existing vulnerabilities in the software or firmware, but does not eliminate the attack surface itself. Option C is incorrect, as patching is not always required per the vendor contract, although some vendors may provide support or incentives for patching. Option D is incorrect, as patching does not allow for creating a honeypot, which is a decoy system that is intentionally left vulnerable to lure and trap attackers.

In a PaaS model, the cloud provider is responsible for managing and maintaining the underlying infrastructure, such as the hypervisor, the virtual machine, and the network. The tenant only needs to focus on developing and deploying the application, which runs on the cloud platform. The tenant is responsible for ensuring the security and availability of the application, as well as applying any patches or updates to the application code or configuration12. References :=
