479.0. "Community Strings and Security..." by PADNOM::PEYRACHE (Sarip Torppus Lanoiger) Tue Nov 09 1993 10:23

  hi


   Hubwatch for OpenVMS V2.0-1 DECagent90 V1.1


   On the Decagent 90 my customer has defined only one Community with
   a Read-only/Read-Write String Differents:

      (AKA :  Read-only  string "Public")
              Read-Write string "System")

  in fact from my customer point of view ,when you start HUBwatch with community
Public you are only the capability to display Information regarding Modules
in the HUB, you can't modify the configuration.

  Now The problem:


 After firing up HUBwatch with Community Public "Read-only"
 If you select Manage Table in Community Option:

  first of all ,you see all the Read_only and Read-Write Strings for all
communities managed by the agent.

  and if you select the Read-Write String and Make current ,you have now all
  capability (add, delete a module ,disable a port etc....)


 seems to be no really secure (display the Read-Write string and Switch from
  Read-only to Read-write )

 is'nt it ??


 thanks for any comments/feedback/explainations

479.1DENM read-write strings are readableQUIVER::HAROKOPUSTue Nov 09 1993 13:0411
    From a HUBwatch perspective we will display the community table 
    that the DENMA returns to us.  Since the DENMA returns the read-write
    community strings even if you are using a read-only string we decided
    not to screen these out since there is no real security anyway.
    
    I'm not sure why the DENMA returns the read-write community strings
    if the access is read-only.

479.2Yes butPADNOM::PEYRACHESarip Torppus LanoigerTue Nov 09 1993 13:4915
  thanks Bob ,


  Purely security hinds,

  if you start Hubwatch using only-Read Community,
  seems to be no real  good thing to access on write with no     
  restriction(Password) .


   agreed with me ??

479.3better in the 900...QUIVER::SLAWRENCETue Nov 09 1993 14:522
    FYI - The DEChub900 hub manager will not return the read-write
    communities in response to queries using a read-only community
479.4DENMA firmware issueQUIVER::HAROKOPUSTue Nov 09 1993 16:3213
    Part of the problem is that when you start up HUBwatch with a read-only
    community we have no way of knowing (baring trying to set something)
    that it is a read-only community.    When you enter the community
    table window HUBwatch reads the table and displays what the agent
    returns.   
    
    I think that this problem needs to be addressed in the DENMA firmware
    so that read-write strings are not returned when the access is
    read-only.  This is how it works in the DEChub 900.
