Python support arrives in Safeguard for Sudo Nov 30, 2021 Version 1.9 of sudo was released almost two years ago. One of the major new features was support for Python plugins. Previously, you could only extend sudo by coding in C to better suit your environment, which is not the easiest task to manage. Python makes both coding and distributing the results easier. Starting with Safeguard for Sudo 7.2, Python support is also available in an enterprise sudo management solution. ...
Sudo 1.9.8: intercepting commands Oct 6, 2021 A month ago, when sudo 1.9.8 was still under development, we checked out the new log_subcmds option. It allows you log all commands (with some limitations) that are executed by a command started through sudo. For example, you can see if a shell was started through a text editor. The intercept option brings this one step further: you can prevent sub-commands from even running. Before you begin To use sudo’s intercept option you need sudo 1. ...
What is coming in sudo 1.9.8? Aug 31, 2021 Sudo development is at version 1.9.8 beta 3. There are two major new features: sudo can intercept sub-commands and log sub-commands. In this quick teaser I introduce you to log_subcmds. I hope it is interesting enough for you to test it out and provide feedback. So, what is log_subcmds good for? There are many UNIX tools that can spawn external applications. You only see vi in the logs, but can you be sure without session recording that your admin only edits what he is supposed to? ...
Securing the sudo to sudo_logsrvd connection Aug 24, 2021 Using sudo_logsrvd to centrally collect sudo session recordings from your network is a huge step forward in security: users cannot delete or modify session recordings locally. However, by default, transmission of recordings is not encrypted, making it open to modifications and eavesdropping. Encrypting the connection between sudo and sudo_logsrvd can eliminate these problems. Larger environments usually either have in-house PKI tooling in place, or colleagues who know all openssl options off the top of their heads. ...
New in 1.9.7: using sudo_logsrvd in relay mode Jun 15, 2021 Relay mode was introduced to sudo_logsrvd in sudo version 1.9.7. But, first of all, what is sudo_logsrvd? It is the sudo recording service that allows you to collect sudo session recordings centrally. Using relay mode makes it possible to collect sudo session recordings even when the central service is inaccessible and provides you with a single exit point from your network. In this blog you will learn why relay mode is important and how you can test it. ...
Analyzing your sudo session recordings with One Identity's SPS May 18, 2021 Sudo is an open source application allowing you to execute commands as another user. Safeguard for Privileged Sessions (SPS) by One Identity is commercial software that allows you to control, monitor and record privileged access. Starting with the upcoming SPS version 6.10 you will be able to collect and analyze sudo session recordings in SPS.

Alerting to many different services using Python and sudo 1.9 Apr 20, 2021 Before version 1.9 was released, alterting in sudo was limited to e-mail messages. If you wanted to send alerts somewhere else, like Slack, you could only do this using external applications, like syslog-ng. Beginning with sudo 1.9, there is an Audit API that can be called from Python. Previously, we provided you with a simple example that show how to print some debug information to the terminal. In this blog post we will extend that example with Apprise, a universal Python notification library. ...
Fuzz testing sudo Mar 30, 2021 Version 1.9.6 of sudo was released recently. This is primarily a bug fix release with almost no user visible changes. One of the changes visible to developers is that support for fuzz testing was added. What is fuzz testing? According to the Wikipedia: “Fuzzing or fuzz testing is an automated software testing technique that involves providing invalid, unexpected, or random data as inputs to a computer program. The program is then monitored for exceptions such as crashes, failing built-in code assertions, or potential memory leaks. ...
Sudo on OpenBSD, DragonFlyBSD and NetBSD Feb 23, 2021 My FOSDEM talk in the BSD devroom showcased what is new in sudo and syslog-ng and explained how to install or compile the software yourself on FreeBSD. I am a long-time FreeBSD user, started with version 1.0 in 1994. But soon after my talk I was asked what I know about the other BSDs. I knew that all BSDs have sudo in their ports system, but had no idea what shape those ports were in. ...
Sudo on FreeBSD Jan 26, 2021 While FreeBSD does not install sudo as part of the base system, you can easily install it yourself. If you do not need anything more than basic functionality, you can install the binary package using the pkg command. Most users belong to this group. If you need advanced functionality, like Python support, you will have to compile sudo yourself from ports. Are you surprised by the mention of basic and advanced functionality for sudo? ...
