Lets do this with a elimination process. With padding messages you can countermeasure traffic analysis because you add garbage information to the message to let in end in a fixed length, this can confuse the analyzer. Sending noise on the communication line could also countermeasure analysis because the analyzer don't now how to differentiate between real information and noise. You can also covert channel analysis. Eavesdropping does not apply in this situation, its not considered a counter measure to traffic analysis.

Explanation:
Writing is not a component of media viability controls.
Media viability controls are implemented to preserve the proper working state of the media, particularly to facilitate the timely and accurate restoration of the system after a failure.
Many physical controls should be used to protect the viability of the data storage media. The goal is to protect the media from damage during handling and transportation, or during short-term or long-term storage. Proper marking and labeling of the media is required in the event of a system recovery process:
Marking. All data storage media should be accurately marked or labeled. The labels can be used to

identify media with special handling instructions, or to log serial numbers or bar codes for retrieval during a system recovery.
Handling. Proper handling of the media is important. Some issues with the handling of media include

cleanliness of the media and the protection from physical damage to the media during transportation to the archive sites.
Storage. Storage of the media is very important for both security and environmental reasons. A proper

heat- and humidity-free, clean storage environment should be provided for the media. Data media is sensitive to temperature, liquids, magnetism, smoke, and dust.
Incorrect Answers:
A: Storage is a media viability control used to protect the viability of data storage media.
C: Handling is a media viability control used to protect the viability of data storage media.
D: Marking is a media viability control used to protect the viability of data storage media.

One the most secure implementations of firewall architectures is the screenedsubnet firewall. It employs two packet-filtering routers and a bastion host. Like a screened host firewall, this firewall supports both packet-filtering and proxy services.
