HP-UX System Administrator's Guide: Overview

Data Protection Tools
Security of servers, networks, and data has never been more important than it is today.
HP-UX has many tools for securing your servers and data.
For most HP-UX users, securing your servers and data from unauthorized access ranges
from important to critical. Unauthorized access (whether malicious or accidental) is
only one of many threats to the integrity and security of your data. Others include:
• Accidental destruction or removal of data by poorly behaving software
• Accidental destruction or removal of data by authorized users
• Storage device failures
• Other hardware failures that corrupt data
• Other hardware failures that prevent access to data
• Physical plant and equipment destruction (for example from fires, floods, and
earthquakes)
There are HP-UX based tools to protect your data from all of these potential threats.
Protecting Against Unauthorized Access to Your Servers and Data
HP-UX can be configured to run in either of two modes:
Standard Mode Offers traditional security features found in UNIX systems
(accounts, groups, file access privileges, and so on). Passwords
are stored (encrypted) in the /etc/passwd file.
In addition to the traditional security features mentioned previous,
HP-UX running in standard mode has an extended set of security
features (for example HP-UX Shadow Passwords) that
significantly increase the security of your system without having
to convert it to Trusted Mode. These additional features are fully
explained in the HP-UX 11i Security Containment Administrator’s
Guide. Additional security information is located in the HP-UX
System Administrator’s Guide: Security Management document.
Trusted Mode Offers a complete C2-level set of security features. Passwords are
not stored in the /etc/passwd file, but are instead stored in
/tcb/files for additional security.
Protecting Against Data Loss
The best way to protect your data against loss is to have another copy of the data
somewhere when the primary copy is lost. There are many technologies that will help
you make those extra copies. These include:
Backups There are many ways in HP-UX to backup your
data:
