There are no protections. Your activity is effectively public. By policy at the Federal level you are typically allowed an amount of browsing that does not cause undue burden to the network / taxpayer. Practically, this is not rigorously enforced unless the site is explicit or taking your network down (or causing security problems). Most agencies are Ok with a bit of casual browsing / Facebook (et al) / news stuff and have policies to that effect but if you are concerned about privacy then you're out of luck and there's a nice monitoring statement on each login to that effect. Keep personal stuff segregated completely if you're concerned about it.
