Foot printing is the process used to gather information about a company’s internet presence. Very common tools such as whois, dig, IP address and port scanners, can yield a lot of information that gives clues to where and how to attack. It is not possible to stop or eliminate a large portion of the information.

A lot of the information must be public and available for anyone to discover. There are a number of things that can be done to prevent the release of too much of the private information. One of the first is to use private registration with your domain register like GoDaddy. (Add, 2019). This prevents a lot of the contact information that would be generally available via whois. A good rule of thumb is to use mail box aliases in the whois like [email protected] , or [email protected] .

DNS is another large leaker of information that can be queried. Companies need to make sure that there public DNS system are not set up to allow zone transfers, and only contain the DNS records of public facing servers. You need to have a public and an internal DNS. Public DNS server should never expose any Internal IP addresses.

External IPS that can detect and stop both IP address and port sweeps. If this can be blocked it makes it much more difficult to discover that is available. However, a hacker with enough patience can just slowly scan the network and circumvent the IPS.

Use of no-cache options on web pages is also a good way to help hide your pages from search worms.

The last item that I feel does not really stop footprinting, but having a comprehensive vulnerability scanner that runs regularly and the output is reviewed. This will help you in understanding what systems are exposed to the internet and what vulnerabilities exist. Using this information, you can decide if the server should be on the internet, and it is does which ports are open. Locking down any that are not needed.
