I've been reviewing my router logs and noticing this particular part that bothers me:

And what part was that?

I just see "<span id="INSERTION_MARKER">" in your post.

What is DOS, apart from the Disk Operating System installed on older computers?

Answer
Why Do You Think A Denial Of Service Attack Occurred?
by Grif Thomas Forum moderator / July 5, 2011 3:06 AM PDT

Please note that routers and firewalls keep track of every packet that passes through.. A "Distributed Denial of Service" attack is one that is spefically aimed at your system where multiple machines flood your internet connection with millions of packets to stop normal data transfer from occurring on your machine. . Generally , such things occur on computers where there is a reason to stop such data from moving through the system. Although it's possible for it to occur, for most home users, it's not worth the effort of the DDOS instigator to do so.

On the other hand, there are all sorts of internet probes which are constantly scanning the internet for holes in various systems.. They automatically scan for any vulnerability, any where, and may show up in your scan as repeated attempts at your system.. Indeed they're not a good thing, but other computers are probably getting the same things as well..

As long as you've got all your firewalls setup correctly, so they're blocking such attempts, you're pretty much stealthed on the internet. The logs are simply recording what they're blocking.

Hope this helps.
