Transaction security via Internet, Phone and Mobile Banking

NBG i-bank services use state-of-the-art security technology to ensure that your Internet, Phone and Mobile Banking transactions are fully protected:

  • Data confidentiality and protection against tampering
    We ensure maximum data confidentiality and protection against tampering in your Internet and Mobile Banking via the Secure Sockets Layer (SSL) communication protocol, which is deployed in strong 128-bit encryption.
  • NBG authenticity
    NBG has been issued with a Web presence authentication certificate from Verisign, the leading certificate authority worldwide. The certificate is displayed on the system's home page and is available to the user throughout the use of Internet Banking services.
  • User authentication
    - Every user of Internet, Mobile and Phone Banking has his own, unique UserID and Password which is the same for the three i-bank electronic banking services.

    - The Internet and Mobile Banking application “recognizes” authorised users and allows them access to the system on the basis of their UserID and Password.

    -
    User authentication in the Phone Banking application is verified by means of the users’ unique User ID in combination with the OTP (“one-time password”: a single-use numeric code) generated by the users’ personal i-code device.

    - On a fourth attempt to enter an invalid code (UserID and /or Password and /or OTP), access to the system is automatically blocked (the user is deactivated) for your own protection. To regain access to these services, you will need to phone our Contact Center (at 181818 from Greece or +30 210 4848484 from abroad) and follow the instructions of one of our agents.
  • Preventing unauthorised access to the system
    If no transaction activity has taken place for more than 10 minutes in the Internet or Mobile Banking application, the system automatically returns to the home page and you need to re-enter your codes if you wish to continue. This helps prevent unauthorised access to the system.
  • Additional security for money and security transactions
    - Additional security for money and security transactions (e.g. change of password) via Internet, Mobile and Phone Banking is provided by one-time passwords (OTPs) generated by the i-code device.

    - The i-code is a small, electronic device, available to all users of NBG Internet, Phone and Mobile Banking upon their registration.

    - The i-code device ensures that each transaction is indeed being carried out by the holder of that device. Each code is valid for only 32’’ and cannot be used afterwards. Thus, nobody can produce codes and store them for later use. This eliminates the possibility of code interception for use later on (e.g. phishing).

    - Upon completion of the transaction, the three-digit confirmation code that appears on the Internet Banking screen should be the same as the three-digit code generated by the i-code device when pressed immediately afterwards. When carrying out Phone Banking, the three-digit code is transmitted either via the automated voice system or via an NBG Agent, depending on the transaction mode that the customer has chosen.

    - In addition, these codes are generated on the basis of the 3DES strong encryption algorithm, ensuring a superior security level certified by leading international organizations.
  • Recording of telephone calls
    All calls made to the Bank’s Contact Center (181818, +30 210 4848484), and via which Phone Banking transactions are carried out, are recorded by the system for security reasons.
  • Mobile Banking transaction security
    When carrying out transactions using your Smartphone, you enjoy the same level of security as when you bank via Internet Banking, as described above. In addition to these security features, our technology ensures that no personal or transaction data is stored on your mobile device after the transaction is concluded.

 

For our business customers, in addition to the technologies already outlined, NBG provides your company with additional functional capabilities for safeguarding and controlling transactions via Internet Banking:

  • Different authorisation levels and access rights
    Designating authorised users (Job Positions) for Internet Banking, with different authorisation levels and access rights: This conveys rights and restrictions to each Internet Banking user in accordance with the company specifications.
  • Job Position Administrator
    The Job Position Administrator defines and manages the powers of each and every Job Position from wherever there is an Internet connection, without the mediation of the Bank. Furthermore, the JPA has full supervision of Internet Banking use, i.e. the activity of each Job Position.
