[Endpoint Protection and Detection] A company has 5000 Windows users on its campus. Which two precautions should IT take to prevent WannaCry ransomware from spreading to all clients? (Choose two.)

WannaCry ransomware is a type of malware that encrypts the files on the infected devices and demands a ransom for their decryption. It exploits a vulnerability in the Windows SMB protocol that allows remote code execution. To prevent WannaCry ransomware from spreading to all clients, IT should take the following precautions: Ensure that noncompliant endpoints are segmented off to contain any potential damage. This means that any device that is not patched, managed, or compliant with the security policies should be isolated from the rest of the network and given limited access to resources. This can be done using Cisco Identity Services Engine (ISE) and Cisco TrustSec, which can enforce dynamic segmentation based on the device’s identity, posture, and context. This way, IT can prevent the ransomware from infecting other devices and reduce the impact of the attack12 Perform a posture check to allow only network access to those Windows devices that are already patched. This means that IT should verify that the devices have installed the latest security updates from Microsoft that fix the SMB vulnerability. This can be done using Cisco AnyConnect Secure Mobility Client, which offers a VPN Posture/HostScan Module and an ISE Posture Module. Both modules can assess the endpoint’s compliance for things like operating system, patches, antivirus, antispyware, and firewall software. If the device is not patched, it can be denied access to the network or redirected to a remediation portal13 : 1: Cisco AnyConnect Secure Mobility Client Administrator Guide, Release 4.0 - Configure Posture 2: Can We Trust Your Device?
