Detailed Information for the Best Practice: 9-7-8077

Number 9-7-8077
Priority Highly Important
Description Compensating Control for Weak Authentication Methods: For Network Operators and Service Providers legacy systems without adequate access control capabilities, access control lists (ACLs) should be used to restrict which machines can access the device and/or application. In order to provide granular authentication, a bastion host that logs user activities should be used to centralize access to such devices and applications, where feasible.
Network Type(s) Cable; Internet/Data; Satellite; Wireless; Wireline
Industry Role(s) Service Provider; Network Operator
Keyword(s) Cyber Security;Intrusion Detection;
Reference/Comments In the long term, the vendor should be engaged to correct the issue, either by allowing the built in method to be changed periodically, or by allowing the user to add complementary authentication means that they control, hence creating a two-factor authentication.
Where authentication methods must be shared, create an enforceable authentication method policy that addresses the periodic changing of the characteristics of the authentication method, and the dissemination of the method based on the principle of least privilege. If the authentication methods are shared, policy to implement least privilege access and periodic authentication characteristic change should be developed and implemented. Consider replacement of device at end of life, especially if the device is protecting key equipment. Implement a periodic audit program to verify policy compliance.Garfinkel, Simson, and Gene Spafford. Users and Passwords. Practical Unix & Internet Security, 2nd ed.
