Connections Status field descriptions

Last Updated : Apr 28, 2016 |

Summary section

The Summary section displays the total number of Active Connections and the number of connections that are incoming, outgoing, TCP, and TLS.

Connection Filter section

Use the Connect Filter section to define a filter and to display the connection list based on the defined filters. A filter can be an FQDN or an IP Address and mask.

If you select Non-compliant NIST TLS Only, the page displays only the TLS connections having an algorithm that is not compliant with the NIST SP800-131A recommendation.

Connection List section

The Connection List table displays basic information of all the active connections. The following definitions apply to several of the fields:

  • A Acceptable. The algorithm and key length are safe to use. No security risk is currently known.

  • D Deprecated. The use of the algorithm and key length is allowed, but the user must accept some risk.

  • X Disallowed.

  • N Not approved.

  • R Restricted. The use of the algorithm or key length is deprecated, and there are additional restrictions required to use the algorithm or key length for applying cryptographic protection to data.

  • U Unknown. The system cannot determine the status.

Name

Description

Details

Show or hide the detailed information of the selected connection link.

Dir

Link direction (inbound or outbound).

Local Port

Local Security Module port.

Remote IP

Remote IP address.

Remote Port

Remote port.

Remote FQDN/IP

Remote FQDN or IP address.

Transport

Transport protocol (UDP, TCP, TLS).

Policy

Security Policy (Trusted, Default, Instance)

Cert Sign

Certificate Signature. Digital signature algorithms (for example, RSA or DSA) and the cryptographic hash function (for example, SHA) of the certificate in use by the TLS connection.

Key Exch

Key exchange algorithm (for example, RSA, DSA, Diffie-Hellman,) and key bit length (for example, 1024, 2048) to establish symmetric keys between the endpoints on the TLS connection.

Encryption

Cryptographic operation that provides confidentiality of the data being carried on the TLS connection.

MAC

Message Authentication Code algorithm (for example, SHA) that authenticates the TLS data and provides integrity and authenticity assurance on the message.

Connection Details section

The Connection Details section displays detailed information for the selected connection.

Name

Description

Direction

Link direction.

Creation time

Link creation time.

Last message received

Last message received time.

Last message sent

Last message sent time.

Messages/Bytes Received

Received message count and byte count.

Messages/Bytes Transmitted

Transmitted message count and byte count.

Messages/Bytes Dropped

Dropped message count and byte count.

Subject

The subject field identifies the entity associated with the public key stored in the subject public key field of the X.509 certificate.

Alt Subject

Alt subject is an extension to X.509 that allows various values to be associated with a security certificate.

CA

The issuer who signed the certificate.

Cipher

The negotiated TLS cipher suite. The cipher suite includes the Key Exchange, Encryption and MAC algorithms.

Public Key Algorithm

The encryption algorithm of the public key (e.g. RSA, DSA or Diffie-Hellman).

Key Size (bits)

The Public Key length.

q bits size

For DSA public keys, this represents the q parameter size.

Signature Algorithm

The identifier for the cryptographic algorithm used by the CA to sign this certificate.

MAC Algorithm

The Message Authentication Code (MAC) algorithm to verify data integrity.
