Sql connection security

Hi friends,

I use the code bellow to connect to my database on my website:

string tempstr = "Data Source=" + "72.55.---.---" + ";Initial Catalog=-------;Integrated Security=False;Persist Security Info=True;User ID=" + "MYUSER" + ";Password=" + "MYPASS";

SqlConnection con = new SqlConnection(tempstr);
con.Open();

Is it secure enough ? or someone who is not professional hacker can capture the username and the password which is sent from his/her computer to my database !?

thanks in advance.
