It's 3 days old but I thought I'd share it anyway.
Security at BRU is 'okay'. Check-in for LY takes place amongst other airlines. As far as I can remember from my last LY flight boarding is towards the end of the terminal so that it has its own security (similar to US airlines), but don't quote me on that, I haven't taken a BRU flight for TLV for some time now.
