If you’re going to network your computers together, you have to decide what technologies to use. You should base that decision on what the competing choices do well and what they do poorly.We start by looking at some of the most important characteristics in networks and then look at specific technologies and how they relate to those characteristics.As in the real world,though, attacks and threats on the Internet don’t just occur randomly — they happen in predictable ways. Most of the attacks you’ll hear about in the media occur at the application layer, going after Web servers, browsers, and the information they have access to, but application layer attacks on unprotected or vulnerable services are common, as are data link layer attacks on unprotected wireless networks. Our technicians provide on site set up to secure home and business network. The capability to screen traffic by our computer technicians based on message content makes it possible to create filters for objectionable content, such as sites inappropriate for minors although it’s very hard to define rules for that filtering, which is why there are companies whose business is to sell lists of sites you might want to filter for various reasons, along with filter software to use based on those lists).We can also secure your network through content screening that also makes possible defenses against specific attacks by looking for telltale signatures in the incoming attacking packets. When the firewall detects those signatures, it discards the packets and logs the events.
