Hp-ux: which processes/services can be disabled ?

[Augusto Vinhaes]

There are some hp-ux processes such as sendmail that represents a security problem. I’d like to know if there is a list of daemons and services that can be disabled to protect the system.
Regards,

It really depends on how you use the system.

If they are not in use then things like:

sendmail
SNMP
r* daemons
Any of the 'small services' (like daytime, time, echo, discard, chargen) SHOULD be disabled
telnet
ftp

You just have to look at your particular environment and see. There is not a one-size-fits-all solution.

Augusto,

Attach you will find list of services from inetd.conf file.

It's not needed to have Sendmail daemon (-bd) running if you just want to sent emails.
But there are always exceptions:
example:
- Mail API provided in Java
- Oracle utl_smtp

Have a look at HP-bastille:

GoodLuck

There is no list of network services that you should disable except in /etc/inetd.conf. Put comments in front of every line and you will disable all network services including telnet and ftp. Now if you need these services, you'll have to re-enable them. The system administrator must know what services are needed and make sure they are enabled. Lacking that information, it is more secure to disable everything and then add back what you need.
