When considering the security of the different types of transmission mediums, here’s how they generally compare:
-
Infrared: Infrared communication is relatively short-range and often requires line of sight, which can make it somewhat secure due to its limited range. However, it's also susceptible to interception by anyone within the line of sight and can be disrupted easily.
-
802.11n: This is a standard for wireless networking. While it can include security protocols like WPA2, the fact that it is wireless makes it more vulnerable to eavesdropping and other attacks if improper security measures are used.
-
Fiber-optic: This is generally considered one of the most secure options. It carries signals as light through glass fibers, making it immune to electromagnetic interference and difficult to tap without detection. Any attempts to tap into fiber optic cables can usually be detected.
-
UTP (Unshielded Twisted Pair): UTP cables are commonly used in networking but are more susceptible to crosstalk and electromagnetic interference. They can be tapped relatively easily if physical access is gained.
Based on this analysis, fiber-optic is typically regarded as the most secure option due to its difficulty to intercept and resistance to external interference. So, you should tell Marcos that fiber-optic is the most secure among the choices provided.
