IP Auto BlockBut if you've opened up the unit to accept connectivity from the outside world via the Internet you would be well advised to regularly log in as the admin and review the system logs. I didn't notice much activity at first when I allowed remote access to the Diskstation, but recently I started seeing regular attempts to login from unknown sources. Several each day like these:
It's really unnerving to see that. I'm not naïve but my server is literally a tiny speck of nothing in the universe and has nothing of value to anyone but me. Yet the universe must be filled with pinheads who have nothing better to do than try and hack random IP addresses. Actually, it's highly likely the login attempts aren't being done by a human but by a bot that's already found its way onto other servers and is just probing.
The Diskstations have a feature called IP Auto Block. You can find it in the Control Panel of the Synology server admin tool. Turning it on will make the Diskstation automatically block any IP communication once it has witnessed five failed login attempts. I highly recommend you turn this on. Since turning it on my Diskstation has regularly been blocking several addresses each week. Ye gods, is there no honor left in this world?
