I only stayed in the brook street accommodation for about a week in my first year. I did not like them at all as they look like a prison. I didn't mind my room after I got used to it and made it comfortable for myself, but I never got used to the coed shared showers (everyone never seemed to care for them, so they were often dirty). Nonetheless, the security seemed good (you had to sign in and out at the gate before entering and before leaving). I can't comment much on the new accommodations near Morrisons (Hughenden), but they are good (according to what the students living in them said). The security there is apparently good as well. The pictures pretty much speak for themselves. You can tell just how good they are (the pictures are not lying this time). All in all, I would recommend the Hughenden accommodations for any first year student coming to Buckinghamshire New University!
