Moving Beyond "Compliance Think" in Online Banking Security
One of the greatest threats to the implementation of strong security controls is "compliance think" -- the phenomenon of working to meet compliance requirements, rather focusing on action that meets the need identified by the guidance.
Compliance think led the industry to find the lowest common denominator for many security solutions - what would be the fastest most cost effective way to pass a compliance audit? While this approach certainly raised awareness for the security industry as a whole, the solutions deployed largely created the illusion of security, rather than actually making customers' online experiences more secure. Many solutions promised to provide a broad range of protection for online activity, but the financial industry has discovered that these solutions have fallen short of keeping up with the evolving threat landscape.
Online threats are evolving, and it is imperative that security solutions achieve the transaction safety that customers are demanding - not simply meet regulatory requirements.
The health of any economy can be roughly charted as an inverse relation to the number of bank robberies in a given area: bad economy, more robberies. With a global recession, we've seen a rise in the availability of software made to attack financial web sites, as well as highly organized crime groups, and so the number of "virtual" bank robberies continues to rise relatively unabated. It seems the applied security solutions in the United States today have done little to stop online theft and fraud.This demonstrates that "compliance think" has provided a pass mark on the compliance regulation, but not complied with the intention of regulation, which is the protection of online transactions.
Financial institutions of all sizes must now evaluate their current security solutions and gauge their effectiveness against the rapidly changing threat landscape. Phishing and other social engineering attacks will always be a threat and should be addressed with ongoing consumer/employee education. The solutions that will provide real protection and survive a security review are those that can defend against sophisticated, technology-based attacks that occur without the end user involvement.
To defend against Man-In-The-Middle (MITM) and Man-In-The-Browser (MITB) attacks, financial web sites must implement transaction-specific authentication in addition to user authentication. This is a move beyond the passive authentication used for most retail banking applications and many cash management applications, beyond one-time passwords (OTP), even beyond Challenge/Response (C/R) solutions. These solutions have provided security layers, but stop short of protecting online transactions from attack.
Transaction-specific authentication, also called transaction signing, is a method for verifying the integrity of the financial transaction. This ensures that online transactions received by the bank are exactly the transactions the customer intended to perform. In this model, the online customer would be provided with a token (i.e., smart card, USB stick, etc.) that provides the ability to verify the transaction with a PIN or passphrase. With this technology in place, additional capabilities such as secure document signing also can be implemented.
The typical end user does not fully comprehend the sophistication of new attacks. They trust their financial institutions to provide a safe online experience. Online threats are evolving, and it is imperative that security solutions achieve the transaction safety that customers are demanding - not simply meet regulatory requirements.
