DDOS Attacks

[#1]

Does anyone have experience of being DDOS attacked?
I have a home Broadband wired and wireless network and keep on receiving 'Security Messages' from my router each morning.
I have sent a copy of a typical string of messages to Plusnet tech' support but they say its something they cannot help with! Except telling me that it looks as if I'm being DDOS attacked.
I have read the Wiki on the subject and searched on the web but cannot find whether it is harmful to a single user and, if so, how to prevent it/them.
In fact I'm not really sure what it really does to other than a larger commercial network, rather than a single, home network.
Any thoughts and advice would be gratefully received.
Thanks in advance.

Post a typical string here - not too long please

If you're not experiencing poor performance of your broadband or router, then the "attacks" aren't causing any problems.
The messages could just be false alarms, especially if you use peer to peer software or anything else that uses large numbers of connections.

I've checked your account and can't see those anywhere. I'm sure we can have a look for you once they've been posted here. I'm sorry if support hasn't been up to scratch.

If you get the odd one or two its not a Ddos just the firewall over reacting, but if you get thousands in minutes that is a Ddos.  Ddos attempts to use all your bandwidth to cripple your connection and possibly crash your router.

Thanks Adam.
Please look at Plusnet Help Assistant's Question/Ticket #64469324 where you will find my request for assistance and where I attached a copy of a typical log received from my router alerting me of a security breach.
You will also find the response of your colleague.

Thanks guys, I'll just ignore it then.

Hi goldford,
How often is this happening, is this having any impact on the quality of your service?
If it's having no effect on your service then I wouldn't worry about it as your router appears to be doing what it should be and blocking any attempts.
