Security risk or Something to be concerned about?

Hi all. I noticed in my connection log that after I did an update for a Java Program, about 5 minutes later I had the following entry in my connection log. I did not make an out bound request as far as I know:

9:08am  Inbound connection   127.0.0.1   local service port 50750  from 127.0.0.1 remote service port 50751

0 bytes sent  40 bytes received     

9:08am Outbound connection   127.0.0.1   local service port 50751  from 127.0.0.1 remote service port 50750

40 bytes sent  0 bytes received 

9:09am Inbound connection   127.0.0.1   local service port 50752  from 127.0.0.1 remote service port 50753

0 bytes sent  40 bytes received     

9:09am Outbound connection   127.0.0.1   local service port 50753  from 127.0.0.1 remote service port 50752

0 bytes sent  0 bytes received  

1. I am most concerned about the unsolicited inbound request

2. Is this normal?

3. Does this show some type of security risk or intrusion?

Again most concerned about the unsolicited inbound

I use Norton Antivirus 2008 and a Vista Home Premium OS with the Vista Service Pack 1

All updates are current

Re: Security risk or Something to be concerned about?

127.0.0.1 is the standard IP address used for a loopback network connection. This means that if you try to connect to 127.0.0.1, you are immediately looped back to your own machine. If there is any inbound/outbound connection to 127.0.0.1, you are connected to your own machine. In other words, 127.0.0.1 is your computer itself.

Another name for 127.0.0.1 is localhost. Although 127.0.0.1 is the most commonly utilized address for localhost, any IP address in the 127.*.*.* range should also function in the same manner.

So why would my computer being doing this? Would it have to do with updating the Java program?

Your comp. connects to the WWW through 127.0.0.1 and the WWW connects to your comp via 127.0.0.1

Nu2it, since the local and remote addresses are both 127.0.0.1, this is your computer talking to itself. This is a common means of communication between two programs on the same machine. This has nothing to do with Internet communication and is completely safe.

Re: Security risk or Something to be concerned about?

Cool Thanks. Does it just randomly do that? Or was it stimulated by my running and installing a Java update?

I think, it is performed randomly as a basic test of the functionality of the IP stack in the operating system automaticaly.

As I said, it's communication between two programs (although it could be a program talking to itself too). With some programs you'll see this all of the time, others, not at all. I don't know enough about how Java update works but it could be related to that.
