This Technical Support Note gives guidelines on how to mass change user accounts to Nokia base stations. Both service and element manager user accounts are handled in this TN.
If default user names and/or passwords are used, this creates vulnerability which can be exploited if user have access to base station, certain applications, and usernames / passwords.

Nokia have got information that base station user account information might not have been changed during commissioning: using default account information creates vulnerability risk as those default usernames and passwords might be available from internet. Similarly tools used for local base station operation and maintenance are widely used and might be available from internet. Thus it is advised to change each base station’s account information regularly. There are two kind of user accounts at the base stations: Service account and Element manager user account.
Also called sometime as BTS Element Manager user account. BTS Element Manager is used for BTS management in general. BTS Element Manager is using the account. And for example BTS has TRS web page which us es this account for login. Plus there are other tools, like command line tools which use this account. BTS local operator user account, called Nemuadmin, comes along with a default passwo rd. The user can connect to the BTS site locally or remotely using BTS local operator user account. Local connection means direct connection from a PC with BTS Element Manager to the BTS using ethernet cable with RJ-45 connector. Remote connection can be established through data communication network (DCN). BTS Element Manager is a Java based application for maintaining and commissioning BTS and Flexi Transport element.
Passwords change for BTS local operator user account password and/or Service account password must be done cluster by cluster (not the whole network at once). All the used tools for maintenance/service must be checked after passwords have been o change to first cluster Tools to be verified are those which use the passwords.
As the default Nemuadmin password does not fulfill the Nokia local account policy rules, You cannot change the account password back to the default anymore (restore nemuuser) after user password has been changed.

Nokia internal root user account, called toor4nsn (in some GSM sites called as a ‘root’) , comes along with a default password. This user account is created for Nokia internal use only to access on-site Base Station (in service SSH/telnet session) to log-files, internal counters, diagnosis information etc. The SSH access to a Base Station is deactivated by default. The activation requires the authentication with the BTS Site Manager or Transport Web interface with BTS local operator user account. Therefore the person who wants to activate SSH/telnet to get access as the toor4nsn user must know the operator used username and password to activate SSH/telnet access (or ask another authorized person to do so). Due to the reason, that the default toor4nsn password is being publicly known (as it has been disclosed on the Internet), therefore it is recommended to enable SSH access to Base Station on a need basis only. If permanent SSH access to Base Station is required, then in order to block an unauthorized access to Base Station, it is strongly recommended to change the default password for toor4nsn user account according to the instructions provided in this Technical Support Note.
Passwords change for BTS Local user account passw ord and/or Service account password must be done cluster by cluster (not the whole network at once). All the used tools for maintenance/service must be checked after passwords have been o change to first cluster Tools to be verified are those which use the passwords.
o
o
It is not possible to change in NetAct (NEAC tool) the toor4nsn password back to default anymore as the default toor4nsn password does no t fulfill the Nokia local account policy rules. It is possible to set back the default toor4nsn password using “sec_eNodeB” tool. The current password is needed for this.
This Technical Note provides information how to mass change account information remotely after commissioning.
