What Is PDN-SECURITY-MIB?

PDN-SECURITY-MIB is a Paradyne (PDN) enterprise MIB defining security policy configuration for Paradyne access/transport devices, covering access control lists, authentication method selection, and protection of the management plane. It exposes tables of authorized manager IP addresses and their access levels (devSecurityMgrTable and its newer replacement newSecurityMgrTable), along with counts of configured and maximum allowed manager entries. This is a configuration/security-status MIB rather than a hardware-health one: it lets an operator audit which management stations are permitted to reach the device and at what access level, and confirm the device isn't over its manager-entry limit. It appears self-contained with no stated dependency on external standard MIBs. It is typically used on Paradyne DSL/access multiplexer equipment to lock down which NMS hosts may manage the device. Engineers can download the PDN-SECURITY-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PDN-SECURITY-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

What Can Be Monitored

  • configured manager count vs maximum
  • manager IP address entries
  • manager access level (read/write)
  • manager subnet mask scope
  • manager validation enforcement state

Supported Devices

  • Paradyne DSL access multiplexer
  • Paradyne network access device

Monitoring Examples

An administrator would poll devSecurityMgrCurrentNumber against devSecurityMgrMaxNumber to confirm the manager table isn't full, and enumerate newSecurityMgrTable entries (newSecurityMgrIpAddress, newSecurityMgrSubnetMask, newSecurityMgrAccess) to verify only expected NMS subnets have read/write access. An unexpected entry in newSecurityMgrTable with write access would indicate an unauthorized management station has been added, a security concern worth alerting on. devSecurityMgrValidation indicates whether manager-address validation enforcement is currently active.

OIDs
OID symbolicOID numericTypeAccessDescription
INT devSecurityMgrValidation1.3.6.1.4.1.1795.2.24.2.8.1INTEGERread-writeThis object is used to either enable or disable SNMP IP validation. When enabled the first check on any incoming PDU is based on the IP address of the datagram. If the IP address is configured in the devSecurityMgrTable then the community name is checked. If the community name is correct then the lowest access level between the the Table and the community name is taken.
INT devSecurityMgrMaxNumber1.3.6.1.4.1.1795.2.24.2.8.2INTEGERread-onlyMaximum number of managers allowed in the devSecurityMgrTable.
INT devSecurityMgrCurrentNumber1.3.6.1.4.1.1795.2.24.2.8.3INTEGERread-onlyCurrent number of managers in the devSecurityMgrTable.
devSecurityMgrTable1.3.6.1.4.1.1795.2.24.2.8.4not-accessibleA list of the security manager entries. In order to add a new Security Manager the devSecurityMgrIpAddress object must be created first by setting it to a valid IP Address.
devSecurityMgrEntry1.3.6.1.4.1.1795.2.24.2.8.4.1not-accessibleThe SNMP IP Address configuration items.
IP devSecurityMgrIpAddress1.3.6.1.4.1.1795.2.24.2.8.4.1.1IpAddressread-writeThis is used to specify the IP address that identifies the SNMP manager(s) that are authorized to send SNMP messages. An existing Security Manager may be deleted by setting the devSecurityMgrIpAddress object to 0.0.0.0 or by setting the devSecurityMgrIpAddress object to a new IP Address. A new Security Manager may be added by setting the devSecurityMgrIpAddress object of 0.0.0.0 to the new address as long as there is still room for another Security Manager. When ever a new Security Manager is added or an existing Security Manager's IP Address is modified, the devSecurityMgrAccess object is set to the default value of read (1).
INT devSecurityMgrAccess1.3.6.1.4.1.1795.2.24.2.8.4.1.2INTEGERread-writeThis field is used to specify the access allowed for an authorized NMS when Manager Validation is performed. If the IP address for the NMS sending an SNMP message is on the list of allowed managers, this option along with the Community Name access determine the type of access allowed for the that manager. When ever a new Security Manager is added or an existing Security Manager's IP Address is modified, the devSecurityMgrAccess object is set to the default value of read (1). If the index for this object is not in the existing table and if there is room in the table then the index will be used to create a new Security Manager and will be given the requested access level.
newSecurityMgrTable1.3.6.1.4.1.1795.2.24.2.8.5not-accessibleA list of the security manager entries. If an entry is not found in this table, it is added to the table.
newSecurityMgrEntry1.3.6.1.4.1.1795.2.24.2.8.5.1not-accessibleThe SNMP IP Address configuration items.
IP newSecurityMgrIpAddress1.3.6.1.4.1.1795.2.24.2.8.5.1.1IpAddressread-writeThis is used to specify the IP address that identifies the SNMP manager(s) that are authorized to send SNMP messages. This object is the binary AND of SNMP or telnet source IP address and its subnet mask if the subnet mask is available. Subnet mask is assumed to be 255.255.255.255 when not available
INT newSecurityMgrAccess1.3.6.1.4.1.1795.2.24.2.8.5.1.2INTEGERread-writeThis field is used to specify the access allowed for an authorized NMS when Manager Validation is performed. If the IP address for the NMS sending an SNMP message is on the list of allowed managers, this option along with the Community Name access determine the type of access allowed for the that manager. When ever a new Security Manager is added or an existing Security Manager's IP Address is modified, the newSecurityMgrAccess object is set to the default value of read (1). If the index for this object is not in the existing table and if there is room in the table then the index will be used to create a new Security Manager and will be given the requested access level. In addition changing an existing access permission to noAccess invalidates the corresponding row of this table. It is upto the implementation to decide whether to actually remove this entry from the table or not. read (1) ==> no telnet access and snmp read only access readWrite (2) ==> no telnet access and snmp read-write access noAccess (3) ==> no telnet access and no snmp read-write access telnetNoAccess (4) ==> telnet access and no snmp access telnetRead (5) ==> telnet access and snmp read only access telnetReadWrite (6) ==> telnet access and snmp read-write access.
