A networking team asked a security administrator to enable Flash on its web browser. The networking team explained that an important legacy embedded system gathers SNMP information from various devices. The system can only be managed through a web browser running Flash. The embedded system will be replaced within the year but is still critical at the moment.
Which of the following should the security administrator do to mitigate the risk?
- A. Explain to the networking team the reason Flash is no longer available and insist the team move up the timetable for replacement.
- B. Air gap the legacy system from the network and dedicate a laptop with an end-of-life OS on it to connect to the system via crossover cable for management.
- C. Suggest that the networking team contact the original embedded system’s vendor to get an update to the system that does not require Flash.
- D. Isolate the management interface to a private VLAN where a legacy browser in a VM can be used as needed to manage the system.

SIMULATION –
You are a security analyst tasked with interpreting an Nmap scan output from company’s privileged network.
The company’s hardening guidelines indicate the following:
✑ There should be one primary server or service per device.
✑ Only default ports should be used.
✑ Non-secure protocols should be disabled.
INSTRUCTIONS –
Using the Nmap output, identify the devices on the network and their roles, and any open ports that should be closed.
For each device found by Nmap, add a device entry to the Devices Discovered list, with the following information:
✑ The IP address of the device
The primary server or service of the device (Note that each IP should by associated with one service/port only)
✑ The protocol(s) that should be disabled based on the hardening guidelines (Note that multiple ports may need to be closed to comply with the hardening guidelines)
