Security queries

Hi,

I have been asked to look at 2 HPUX 11 servers in a company we have taken over & have some queries.

1. Neither system is set up as a trusted system with no password ageing etc. Passwords held in encrypted form in /etc/passwd. My own servers are trusted systems since day 1. Am I correct in recommending that they should be trusted.

2. Root should only be able to login at console & not ftp - correct? All users are allowed ftp which I don't agree with. No secure ftp
There is no Web console.

3. Ignite not being run - this should be run regularly & the files copied to the oposite server. This is what I do on my servers & need to know if this is correct.

4. Finally, I run SysInfo on my servers once a week on the crontab & copy off the output. There is no SysInfo on these servers. Does this need to be downloaded & installed.

Thanks,

Tim

Re: Security queries

All correct. go ahead and do that. You may also want to check that ignite versions are latest on these systems.

Shalom Tim,

So long as you are not using NIS going for trusted systems is a good idea.

Ignite should be run on all systems once a week . If the system has a tape drive, I advocate make_tape_recovery, if not use make_net_recovery to a NFS shared mount point.

I also recommend downloading and installing Bastille and PERL5 from http://software.hp.com in order to make your system more secure.

root should NEVER have ftp access. Its a major security flaw to permit it and because ftp sends paswords back and forth in clear text, its a great way to get your root password hacked.

Secure Shell (software.hp.com) should be used in place of telnet.

Re: Security queries

Tim,
it's probably down to what you get used to.
Even if the data is not critical, the machine would still give access to your network.
I would certainly go ahead with your suggested changes, even only to get the new systems to the standard required in your company.
May be worhtwhile running a few checks on the systems to ensure they were not compromised. Audit all the users and get them to chnage passwords etc..

Re: Security queries

Hi Tim,
I agree with the earlier replies, but be a bit careful with question number 1.
If you are going to Trusted System mode and are running e.g Baan, you can cause quite a lot of trouble for users and admins since some applications do'nt "talk" with the OS/security system,

Re: Security queries

Hi All,

Thanks for all the replies. The system is only running Oracle so moving to a trusted system shouldn't be a problem.

Where do I get SysInfo to install

Many Thanks,

Tim
