Security hazard log in my router

[depark21]

In my router under security hazard log , the following reads like this:

time, event _ firewall info...Event type=user authentication failure... Details: invalid username.username admin repeated 42 times.

Is this someone trying to access my router/network, ?? Obviously I have changed the default signon.

Thanks

In a word... YES.

There are computers that crawl the internet looking for vulnerabilities. When they hit upon one they start to look for open ports and then attempt to exploit. As a residential user, this is typically not a problem.

Keep the default firewall settings on the router.

When bored... I take a look at my log and perform a WHOIS on the IP's attempting an attack. I've found that most are overseas.

Typically these attempts are to steal processing power not your individual files.
