Anyone who has the minimal knowledge of computer has come across the term hacking. In layman’s term, hacking is gaining illegal access to any resource which is connected to the Internet. Whatever the hacker does once the access and control is gained differentiates the type of hacking.

Whitehat hacking is the ethical hacking which is done to expose the flaws in the security of any website or web server. This is done to further strengthen the security and is, in most cases, authorized by the owner of the website or server.

Blackhat hacking, on the other hand, is the unauthorized hacking of any website or web server and causing loss or damage to those associated with the website.

Believe it or not, even in the 21st century, hacking can be a child’s play. One might simply hack a website or web server for fun. Even with heightened security there are scopes that can be exploited by a novice. It is important that you know about some of these basic hacks and take preventive measures to secure your web server. When possible, always use the services of a up to date expert like BlueCat instead of trying to prevent hacks yourself.

Most common and easiest hacking techniques

DDoS – DDoS stands for Distributed Denial of Service. This is one of the easiest hacks of all. DNS or Domain Name System, which forms the backbone of Internet communication, is one of the most vulnerable targets. Domain names were introduced to make it easy for general users to remember the website addresses. Website addresses that the network understands comprise of a series of digits. Depending upon whether it is IPv4 or IPv6 protocol that is being followed, the address will comprise of varying set of numbers. However, it is impossible to remember this set of number. Thus domain names were introduced which will refer to the website. The domain name server is the dictionary that has the names along with the respective IP address noted for reference. In DDoS attack, the simplest form of attack is sending high volume of request to the server within a very short duration of time. This will create a bottleneck and make the server unavailable to other users. Another trick used by advanced hackers is engaging the internal resources of the server carry out requests in loop making them unavailable to handle external requests from other users.
DNS Cache Poisoning – DNS Cache Poisoning is another highly malicious attack. Unlike the one above it does not make the server unavailable. It actually poisons the DNS directory so that any request to visit the original website will be routed to a rogue site controlled by the hacker. This rogue site will have the exact same interface as the original site. Whenever a user enters confidential information like financial or login data, they get sent to the hacker who can use it for their own benefit.
DNS Rerouting – This is not as malicious as the DNS cache poisoning, however, it works on the same principle. The aim of the attacker is to take the visitors of a site to another site of his/her choice. The other site is not the same site as the one the users are trying to visit but might provide similar services. It is somewhat like hijacking the web traffic midway.
Execution of Remote Codes – This is security flaw which can occur on either the server side or the client side. Small snippets of codes are embedded on the server or the browser which can be used to extract information from the website illegally.
DNS Server Protection

It is imperative that you take DNS protection seriously. There are many modern means of thwarting such attacks. One of the simplest ways is to use a DNS firewall. It is a specifically built firewall which will identify and prevent any attack through suspicious activity detection method. IPv6 adoption is also a means of securing the server. However, the adoption will have to be global for this to be effective. Small steps make major differences. It is important that you take your steps today.
