It would be naïve to expect that online casinos do not face any security risk from unauthorized persons trying to break into their systems. Every second funds are being transferred to and from the Cashier section of the online casino. The information on the credit card numbers and bank account numbers of thousands of customers is stored on their servers. This activity and information is a paradise for hackers. But it would be even more naïve to believe that the online casinos are unaware of the risks and are doing nothing about it.

The most important precaution taken by online casinos is the use of Secure Socket Layer (SSL) data encryption protocols. Under this system all information sent to and from the online casino is first garbled using a code. Any hacker who intercepts this message will not be able to make sense of the message or use it in any fashion. At the authorized receiver’s end only can the message be decoded. As the technology for encryption evolves online casinos are quick to embrace it. Today most online casinos use the latest 256 bit SSL encryption. What this does is ensures that funds being sent to or from the Cashier of the online casino cannot be diverted to a third party account.

The data stored on the servers of the online casino are also protected from unauthorized infiltration. One of the important techniques used for this purpose is the installation of firewalls. Firewalls deny access to unauthorized users. Within the online casino administration there are strict procedures of access to the sensitive information stored on the servers. Only the senior most members of the staff are allowed access and that too through a system of passwords. Every activity made by each staff member is archived so that the security personnel can check for any wrong doing.  The online casino does not design the security systems in the software. This work is entrusted to expert organizations like Thawte and VeriSign. The online casinos carry the logo of these organizations in their lobby. This indicates to the players that the security systems have been independently tested and verified. 

The basic software of the casino is also oriented towards security. An online player can operate his casino account using the log in name and password selected by himself. Further most online casinos provide an account number or pin number that has to be quoted while asking for withdrawals. Most online casinos automatically log out the player when he exits from the casino. The software at some casinos remembers the log in name and password for automatic log in, but allows members to disable this facility. In fact in the interest of security all players should disable this facility.

Because of all these precautions taken it is extremely rare to hear about cases where players were defrauded due to security lapse of an online casino.
