Guidance Regarding Sound Practices for Information Security for Networks

The attached letter from the Federal Reserve Board's Division of Banking Supervision and Regulation and the accompanying paper, prepared by supervision staff of the Federal Reserve Bank of New York, contain important information about sound information security practices that institutions may use to address risks associated with computer networks. A version of this paper was distributed at a security conference sponsored by the Federal Reserve Bank of New York on September 24, 1997. Presentation materials from the conference are available at the Federal Reserve Bank of New York's web site (www.ny.frb.org/pihome/news/speeches).

The guidance presented in the paper does not constitute a regulation and should not be interpreted as such. However, the paper outlines the types of prudent and effective measures that financial services institutions have implemented, are in the process of implementing, or plan to implement to protect information and ensure its integrity, availability, and confidentiality. In this connection, the paper may provide insights and assistance in designing an effective information security program and secure automation systems.

We suggest that the letter and the paper be distributed within your organization to senior management and others with responsibility for network security.
