Hackers are internet users who try to gain an advantage over conventional internet users through the use of tools and tricks which they craft up on their own. Hackers can be on your network without you knowing but if you have a way of detecting them, then you can stay safe in the knowledge that they are not hiding that well. Hackers that are on a network which is secure will try to gain access by use of the authorization page and this will be logged as they keep on trying to gain access to your network. A firewall will also note the access gain attempts from the hackers and flag them as suspicious entries into the network. Hackers will also try to hide behind other identities on the same network or even conceal themselves as other networking devices like routers and this makes it harder for them to be noticed.
There are a number of tools that you can use to detect when the number of users on the network has exceeded what you are used to. A firewall, for one, is a simple piece of software which is used to identify durations in which the network presents an opportunity for the hackers to make an attack into the network. Protecting the network using the firewall also helps to identify when suspicious IP addresses are trying to gain access into the closed off sections of the network. Hackers will be using IP addresses that are not the same as the rest of the addresses being used on the network and this makes it possible to point them out and even block them from gaining entry into resources that are on the network. A hacker that is unwanted on a network will try to conceal their activities and even try to maintain as little a footprint as possible and this is the reason putting in measures in place to keep the hackers off the network works to the benefit of the network users. A hacker that is on a network will also be more noticeable if they are trying to break a password in order to gain access to the network. This is known to generate digital noise and all that data generated as they make multiple attempts into getting into the network makes them easier to catch.
Once you have detected that there are hackers on your network and they are trying to gain access to the traffic you have through methods such as piggybacking, you should secure your resources by cutting off sections of the network which this traffic is coming from. For starters, it will ensure that you have them at bay and that any of the further attempts they will be making on the network will be unable to work. This is not only useful for safe networks but for keeping the resources within the network running uninterrupted and safe all throughout the day. A cleaner network is also easier to maintain and doesn’t take much to secure.
