The debate of encryption of wireless network is never-ending and the correct usage depends on the scenario. For example, Safety officials argue on the usage of encryption for their networks. According to them, using encrypted networks provides a safer environment. On the other hand, adversary makes the opposite call by arguing law-abiding citizens should work without any secrecy as it lets others know what they are up to. They also argued that this will let everyone know what’s going around when a critical situation unfolds.
Not all threats can be prevented, but companies should take every measure to protect their data. This means investing in programs and new technologies that will prevent hackers from getting in and prevent information from getting out.
Hackers can use electromagnetic radiation spying and breach steel walls or use a smartphone’s accelerometer as a Key Logger.
That’s basically what a cell phone jammer is. Depending on the type of signal you’re trying to block, the jammer will create enough noise to scatter the rest on that wavelength.
Think of it like this: If you bring in a bunch of people to that big room, it drowns out the noise of the whispered secrets. Some jammers act like a screaming person who shouts into the ear of whoever is trying to listen in.
“So, do we really need to encrypt the radio transmission? A trade-off is what we are looking at. We cannot have best of all worlds. Any organization looking to encrypt the whole network should view the problem from different angles. They have to keep a balance between the role of law-abiding citizens and their benefits, media role in transmitting breaking news and criminals using the unencrypted data for escaping and planning their next move. Cost is also an important aspect of the infrastructure. Authorities also need to take care of it.
