As part of an updated refinement of procedures, the Israel Defense Forces said, Sunday, that no information was to be posted on the Internet regarding operations, including the placement of forces, names and units, with an emphasis on social networks. The IDF's Information Security branch said that Islamic Jihad sent thousands of threatening messages to soldiers after a reservist posted information about reservists and other soldiers on the map, according to a Sunday-evening report by Channel 2 Television.
The Information Security branch said, "The IDF is familiar with the enemy posts on the Internet and its attempts to carry out psychological warfare." It warned against opening messages with files or links from unknown people or from holding conversations with them. The army said, "Especially at the time of an operation, the enemy is investing considerable effort in searching for information abou the IDF on the Internet, and all military information that goes up on the Internet is a present for him."
