The security services are good for what the do. Nothing too big really happens that would necessitate too much security. For the most part, the security guards have a pretty cushy job. There have been instances of locals coming onto campus and causing some sort of issue, but these usually get resolved. There is only one real entrance onto the campus, so not too much security is even needed. The most you will ever see the security guards get involved with anything is about the parking issue.
The health services are also decent. They provide flu shots and so forth from the nurse's office. One interesting concern is that they do not provide sexual protection such as condoms. Other than that, you can really go to them for just about anything. It would be wise to have a physician in the area just in case, though.
