Safeguard for Sudo 7.1 - Administration Guide

System requirements

Prior to installing Safeguard, ensure your system meets the minimum hardware and software requirements for your platform.

Table 1: Hardware and software requirements
Component Requirements
Operating systems

See Supported platforms to review a list of platforms that support Safeguard clients.

Disk space

80 MB of disk space for program binaries and manuals for each architecture.

Considerations:

  • At a minimum, you must have 80 MB of free disk space. The directories in which the binaries are installed must have sufficient disk space available on a local disk drive rather than a network drive. Before you install Safeguard, ensure that the partitions that will contain /opt/quest have sufficient space available.
  • Sufficient space for the keystroke logs, application logs, and event logs. The size of this space depends on the number of servers, the number of commands, and the number of policies configured.

  • The space can be on a network disk drive rather than a local drive.

  • The server hosting Safeguard must be a separate machine dedicated to running the pmmasterd daemon.
SSH software

You must install and configure SSH client and server software on all policy server hosts.

You must also install SSH client software on all hosts that will use the Sudo Plugin.

You must enable access to SSH as the root user on the policy server hosts during configuration of the policy servers. Both OpenSSH 4.3 (and later) and Tectia SSH 6.4 (and later) are supported.

Processor Policy Servers: 4 cores
Policy Servers: 4GB

Table 2: Primary policy server and host system installation requirements
Systems Required Minimum Requirements
Primary Policy Server

  • Supported Unix or Linux operating system
  • SSH (ssh-keyscan binary)

  • Supported Unix, Linux, or macOS platform
  • SSH (ssh-keyscan binary)
  • Sudo 1.8.1 (or later)

Default Ports

Configure the firewall ports appropriately when installing the Sudo Plugin on separate machines from the policy server.

Table 3: Masterport requirements
Variable Default Port Description
TCP/IP port for pmmasterd. Safeguard uses the masterport to communicate with the pmmasterd (policy server daemon).

Supported platforms

The following table provides a list of supported platforms for Safeguard clients.

NOTE: Beginning with version 7.1, Safeguard for Sudo supports only Linux-based systems for Safeguard policy servers.

Reserve special user and group names

Reserve the following names for Safeguard usage:

  • pmpolicy (user and group)
  • pmlog (group)

For more information, see Reserve special user and group names.

Required privileges

You will need root privileges to install Safeguard software. Either log in as root or use the su program to acquire root privileges. Due to the importance of the root account, Safeguard carefully protects the system against certain accidental or deliberate situations that might lead to a breach in security. For example, if Safeguard discovers that its configuration files are open to modification by non-root users, it will reject all job requests. Furthermore, all Safeguard directories back to the / directory are checked for security in the same way, to guard against accidental or deliberate replacement.
