3.1 ACCESS CONTROL
Control the flow of CUI in accordance with approved authorizations..
Information flow control regulates where information can travel within a system and between systems (versus who can access the information) and without explicit regard to subsequent accesses to that information. Flow control restrictions include the following: keeping export-controlled information from being transmitted in the clear to the Internet; blocking outside traffic that claims to be from within the organization; restricting requests to the Internet that are not from the internal web proxy server; and limiting information transfers between organizations based on data structures and content.Organizations commonly use information flow control policies and enforcement mechanisms to control the flow of information between designated sources and destinations (e.g. networks individuals and devices) within systems and between interconnected systems. Flow control is based on characteristics of the information or the information path. Enforcement occurs in boundary protection devices (e.g. gateways routers guards encrypted tunnels firewalls) that employ rule sets or establish configuration settings that restrict system services provide a packet-filtering capability based on header information or message-filtering capability based on message content (e.g. implementing key word searches or using document characteristics). Organizations also consider the trustworthiness of filtering and inspection mechanisms (i.e. hardware firmware and software components) that are critical to information flow enforcement.Transferring information between systems representing different security domains with different security policies introduces risk that such transfers violate one or more domain security policies. In such situations information owners or stewards provide guidance at designated policy enforcement points between interconnected systems. Organizations consider mandating specific architectural solutions when required to enforce specific security policies. Enforcement includes: prohibiting information transfers between interconnected systems (i.e. allowing access only); employing hardware mechanisms to enforce one-way information flows; and implementing trustworthy regrading mechanisms to reassign security attributes and security labels.
What is a Cybersecurity Compliance Framework?
You don’t need to clutter your security and privacy programs with an ever-increasing number of tools as they become more sophisticated. The Lionfish platform offers a one-stop solution to track progress and monitor any framework, from custom-built ones to highly-specialized and in-demand top security and privacy frameworks and certifications.
With the Lionfish platform, every framework is supported with guided scoping, policies, controls, automated evidence collection, and continuous monitoring, ensuring efficient preparation for audits or attestation in minimal time.
The Lionfish platform is compatible with a wide range of security and privacy frameworks, including:
- CMMC v2
- NERC CIP-002 through CIP-014 Revision 6
- NIST 800-171
- NIST 800-172
- PCI (Payment Card Industry Security Standard)
- SOC 2
- NIST 800-53
- NIST SP800-161 Supply Chain Risk Management
- CIS Framework Controls V8
