The adoption of both authentication and encryption schemes are considered a strong first layer of defence whilst IDS can form a second layer of defence against intruders [17]. Intrusion prevention can be utilised to enhance the defence capability of such networks, but these mechanisms often suffer from drawbacks such as high costs of implementation and limited coverage to prevent attacks [18]. Thus the nature of communications in self-driving vehicles requires technologies such as intrusion detection (IDS) that are integrated with monitoring and tracking systems to detect any abnormal behaviour.

Modern Army command and control systems demand reliable, high-speed transfer of large volumes of data. The communications systems provided by Signals must keep pace with modern information technology. The control of the electromagnetic spectrum offers a decisive advantage in modern warfare and Electronic Warfare, listening to or interfering with enemy electronic transmissions, is a critical contribution by the Signals Corps to the Army's combat capability.
On the battlefield, Signals provides commanders with the means of controlling the battle using road and air dispatch services, radio, microwave, and satellite links. A high technology computer switched digital network, capable of providing a high quality, high capacity, secure communications network is being introduced.
The Corps has recently taken over the responsibility for Army Information Systems. Signal Corps personnel now control large integrated information systems and are responsible for the installation and operation of local area networks using state-of-the-art computer equipment.
Project Parakeet is the Army's mobile Battlefield Telecommunications Network (BTN) which was introduced into service in the mid-1990s through Project JP65.[13] At the time of its introduction, Project Parakeet was considered to be a highly advanced military communications system. It included secure voice and data trunking services.
As computer file systems have grown more sophisticated, the incidence of file corruption has become less common -- but corruption still can cause files to disappear from storage devices. Files can be corrupted by another program injecting bad data or by any type of error that stops the computer from writing the file when saving like power failure and system crashes. Files that haven't been completely downloaded or copied can also disappear from the system if the program handling the data transfer doesn't support transfer resumes. Additionally, hardware and software errors that cause either the file copy process to fail or incorrectly update the file allocation table can also cause files to disappear. Depending on how much of the file is corrupted, it may be recoverable through undeletion. 2ff7e9595c
