workstations and also laptops. For the router you definitely need to protect it from unauthorized access. The router needs to be password protected and you should periodically change that password. For the cable modem you should keep all unwanted ports closed. I would also schedule a regular scan of all the systems. Now for some of these next things I am talking about they will apply to all devices . Disable remote administration. Administration of your router / access point should be "local only"

HDLC‚ and derivatives of HDLC such as LAPB and LAPD. On which OSI layers do switches and router operate? The first layer of the OSI model‚ the Physical Layer‚ is the layer that manages the relationship between devices and a transmission medium. If routers reside on more than one layer‚ what is the difference between the OSI layers? To the best of my knowledge‚ and after much research‚ routers reside on both the Physical layer and the Data Link layer. The Physical layer seems to manage

above problems and makes the network significantly more resilient to attacks‚ particularly the DDoS attack. The approach uses "hardened routers"‚ routers that can do simple cryptographic functions (encryption‚ signatures) on all packets flowing in the network‚ as well as to participate in a hierarchical control network. We show how incremental deployment of such routers can make the Internet safer. Like all things dynamic‚ change is inevitable. Such is the case with your network environment. Upgrades
