Learn More (DoS)

A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a machine or network resource unavailable to its intended users. Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of the efforts of one or more people to temporarily or indefinitely interrupt or suspend services of  high-profile web servers such as banks, credit card payment gateways, and even domain name servers.


These attacks may make it appear that a bankís Online Banking is broken or compromised, but by themselves, these attacks do not threaten the integrity of bank customerís accounts or the bankís ability to operate. Usually, because Online banking systems and websites are somewhat separated from normal bank functions and networks, the bankís data is still available to bank personnel and they can conduct business at branches and answer questions over the phone. 


One common method of attack involves saturating the target machine with external communications requests, such that it cannot respond to legitimate traffic, or responds so slowly as to be rendered effectively unavailable. Such attacks usually lead to a server overload. In general terms, DoS attacks are implemented by either forcing the targeted computer(s) to reset, or consuming its resources so that it can no longer provide its intended service or obstructing the communication media between the intended users and the victim so that they can no longer communicate adequately.


Most DoS attacks are temporary so that they cannot be traced. The experts can usually stop DoS attacks once they are analyzed, but that may take some time. It is impossible to immediately stop all DoS attacks. Therefore, it is likely to affect you sooner or later. Please know that your Bank will do everything possible to minimize your inconvenience.


If you critically need information or services that you cannot obtain because of these attacks, do not hesitate to call the Bank.
