Thanks James for the info.

As I understand from the docs... to harden a HP-UX Box...

I have to install the HP-UX Bastille from the below web-site.

http://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=B6849AA

After installing this tool the server is said to be hardened.

JRS... plz let me know if my understanding is correct else plz help me understand it better.

ya bastille is the good one for HP-UX. also you can use PAM.

PAM, SELinux, TCP Wrapper, IPTABLES is the best way to hardenning in Linux.

In Solaris you can use bastille also.

No. You need to read the documentation I suggested including the links in the HP-UX product spec-sheet.

For example, if you are cold-installing HP-UX 11.23 or later, Bastille is included by default:

http://docs.hp.com/en/5992-1978/ch03s05.html#babhdgia

Bastille can be run to first produce a report of suggested actions. Based on *your* specific needs (including adjustments your users may need to make) you then decide what to harden or lockout. At that point, you run Bastille to actually perform the configuration changes. You need to understand what you want to achieve, why and how is impacts your running environment.

Hi (again):

> what is ment by "lockdown of a system".

"Lockdown" is the action or process of prventing use or intrusion.

Some of the tables in one of the links I offered will help you understand:

Now Correct me If I am wrong:-

Hardning a HP-UX OS

0.Login as root
1.Install HP-UX Bastille with Ignite-UX from the OE cd.
2.First time use it interactivelly (Bastille -X) to build system security config.
3.Answer the Questions which explains a security issue as desired by myself for the perticular Server.
4.Select security levels(Sec10Host;Sec20MngDMZ or Sec30DMZ).
5.Save the configuration and apply changes.

Plz correct me if I am wrong either in the procedure or the sequence of steps if they are incorrect.

Monday I will be Hardning my first Server.. So just wanted to be on the safe side that I have understood the whole thing.

Also I need to know the how to do the same on a SUN & a LinuX Box.Plz help me.

Here's an old but still handy resource for linux hardening

http://www.ibm.com/developerworks/linux/library/l-seclnx3/

There's plenty of linux docs out there, just use google.

Hi DMVams,

Those are the Predefined Security Levels you can do your custom one. Run this into one system based on your security requirement save and apply config file.

Then you can use this config file into another system if your security level is same or you want to use it a base level for all system.

You can visit this site to get guideline

This is totally dependent on your environment. If you answer all the Bastille questions to harden the system to the highest level, you probably cannot login anymore. There is no magic button to push (nor easy standards) that will harden your system. You have to know what services you need and which services you can disable. If that information is not available, harden the system to the highest level and then fix all the failures (login, databases, ftp, etc) as they are discovered.
