Every country has to take precautions, however Israel, has to take more than most. Israel is located centrally to all of their enemies. Israel is a Jewish country that is surrounded by Islamic and Arab countries, this creates a major issue since they share borders.
The Israeli government has to be very careful with what they allow their citizens to post on the internet. According to Tikun Olam, the Israeli Army has begun to take drastic measures to monitor what is posted on social media sites, they are comparing this to "Big Brother". According to Richard Silverstein, "..as it begins monitoring the social media accounts of Israeli journalists and bloggers for potential violation of censorship provisions. At a conference on digital media, the censor, an IDF colonel, announced that her staff would further constrict freedom of the press and speech by assuming the mantle of social media enforcer.."
However, most countries try and take away their citizens freedom to shield them from what they may see on the internet or other media outlets, Israel is doing this to protect their citizens from other countries. If Israeli's put the wrong things on the internet, it may create issues for the country.
Israel is very technologically ahead of most countries, they have created a new system to monitor the internet. According to Col. Sima Vaknin-Gil, "[T]he new system will monitor visual and textual information on social networks such as Facebook and Twitter, on blogs and on traditional news sites. Vaknin-Gil explained that the new system will examine information using keywords labeled in advance. The system will be able to monitor information that was previously difficult to reach.
According to OpenNet, "Although the censorship of information considered vital to national security is a reality, both under law and by voluntary pact, Israel has yet to legally authorize or implement filtering of the Internet. " Israel has to have its guard up at all times, even if it means restricting their citizens from certain content. They are in a very different position then most countries and need to know how to operate as such.
