As with any hardware and software which is connected to a network, the PLAYSTATION 3 can also be prone to malicious attacks when connected to a network. However, we have not received any reports of such attacks to the PLAYSTATION 3.
If you have concerns of malicious attacks, you may wish to verify the firewall capabilities of your network with the network administrator, person who set up your network, or your Internet Service Provider. We also recommend installing a firewall program between your Internet router and your PLAYSTATION 3, in addition to regularly updating your virus definition files.
