You can feel confident against hacker-attacks if you have right security in place. So, what all do you to need to feel confident? What is the right kind of security? What security technologies are available? How you can defend against hacker attacks? How hackers work? Do you really know all? Keep reading to find out.. In order to attack someones network, you will need to know as much as you can about that network, so gathering as much information as possible is pretty much where they all start. The information can be technical or non-technical, for example, the partners of the target can be useful for them to know, the location of all office branches etc. This information can help hackers understand the possible technologies in place to stop them. For the technical side of the information, they will need to know things like, IP addresses and the number of services running on how many servers etc. The more services that are running on servers, the better chance a hacker has. E.g. if server-A only had port 110 open , but server-B had ports, 443, 143, 110, 80, 25 and 21 open, then server-B would be the obvious choice because there are more points of entry. If you can get past the security on one open port, then you get full access to the server, so the server with the most options for entry would be the one to go for. A method of protection that has proved very effective is setting up a decoy server with lots of open ports to distract the hackers from something important on the other servers. As soon as they start the attack on the fake server you can analyse their plans of attack. This method is called the honey pot. Basically, what a honey pot is is effectively a trap designed to detect, distract and generally counter attempts to hack into your servers. Usually its in the form of data or a network that appears to be part of your main system and to contain valuable data, but in fact its isolated and monitored. Honey pots can however carry risks to your network and if they're not properly isolated, hackers can use them to infiltrate your system. There are different types of honey pot and you can differentiate between them simply by the circumstances under which they're used. They can be either: Research Honey Pots or Production Honey Pots. Production Honey Pots: These Honey Pots are used mainly by the bigger companies and corporations in order to increase their overall security. They are easy to use, and only capture a small amount of information which would be useless to a hacker. Research Honey Pots: These are run by volunteers or an educational organisation to simply gather information about how hackers work, their motives and tactics in order to create better protection from them.
