Product Description (also known as SecurityCenter) is a software product that is designed to consolidate asset discovery, network monitoring, log aggregation, and vulnerability scanning into a single location to assess an organization’s security posture using a variety of data. It connects with one or more instances of other Tenable products (Nessus Manager, Nessus Network Monitor, Log Correlation Engine) over secure channels.

The evaluated version of is supported on Red Hat Enterprise Linux 7.

Evaluated Configuration

Security Evaluation Summary

The evaluation was carried out in accordance with the Common Criteria Evaluation and Validation Scheme (CCEVS) process and scheme for the Protection Profile for Application Software, Version 1.3 and Functional Package for Transport Layer Security (TLS), Version 1.1.  The evaluation methodology used by the evaluation team to conduct the evaluation is the Common Methodology for Information Technology Security Evaluation, Version 3.1 release 5. The product, when delivered configured as identified in the guidance document, satisfies all of the security functional requirements stated in the Security Target. The evaluation was completed in December 2020. Results of the evaluation can be found in the Common Criteria Evaluation and Validation Scheme Validation Report prepared by CCEVS.

Environmental Strengths

Timely Security Updates

The TOE developer has internal mechanisms for receiving reports of security flaws, tracking product vulnerabilities, and distributing software updates to customers in a timely manner.

Cryptographic Support

The TOE implements cryptography to protect data at rest and in transit.

The TOE stores credential data and passphrase data encrypted using AES or a password-based key derivation function (PBKDF), depending on the data that is being stored.

For data in transit, the TOE implements TLS/HTTPS as both a client and a server. The TOE implements a TLS server for its administrative interface while it implements a TLS client to communicate with other Tenable products in its operational environment. The TOE supports mutual authentication as a TLS client.

The TOE implements all cryptography used for these functions with NIST-approved algorithms. The TOE’s DRBG is seeded using entropy from the underlying OS platform.

Some product functionality requires the use of SSH; the TOE does not claim SSH functionality as it invokes its platform to implement this.

User Data Protection

The TOE uses cryptographic mechanisms to protect sensitive data at rest. Credential data is protected through the use of a PBKDF while all other sensitive data is protected by the TOE platform’s use of full disk encryption.

The TOE relies on the network connectivity and system log capabilities of its host OS platform. The TOE supports user-initiated and application-initiated uses of the network.

Identification and Authentication

The TOE supports X.509 certificate validation as part of establishing TLS and HTTPS connections. The TOE supports various certificate validity checking methods and can also check certificate revocation status using OCSP. If the validity status of a certificate cannot be determined, the certificate will be accepted. All other cases where a certificate is found to be invalid will result in rejection without an administrative override.

Security Management

The TOE itself and the configuration settings it uses are stored in locations recommended by the platform vendor.

The TOE includes a web GUI and a REST API. The web GUI and REST API enforce username/password authentication using locally stored credentials that are created using the TOE. The TOE does not provide a default user account to access its management interface.

The security-relevant management functions supported by the TOE relate to the configuration of how frequently the various environmental components access network resources and for the transmission and presentation of system, network, and log data that the TOE obtains from its operational environment.


The TOE does not handle Personally Identifiable Information (PII) of any individuals.

Protection of the TSF

The TOE enforces various mechanisms to prevent itself from being used as an attack vector to its host OS platform. The TOE: implements address space layout randomization (ASLR); does not allocate any memory with both write and execute permissions; does not write user-modifiable files to directories that contain executable files; is compiled using stack overflow protection; and is compatible with the security features of its host OS platform.

The TOE contains libraries and invokes system APIs that are well-known and explicitly identified.

The TOE has a mechanism to determine its current software version. Software updates to the TOE can be acquired by leveraging its OS platform. All updates are digitally signed to guarantee their authenticity and integrity.

Trusted Path/Channels

The TOE encrypts sensitive data in transit between itself and its operational environment using TLS and HTTPS. It facilitates the transmission of sensitive data from remote users over TLS and HTTPS.

The TOE may also invoke OS platform functionality to establish SSH communications with an instance of Tenable Log Correlation Engine in its operational environment.
