How to Activate Policy Caching for EPM-UL Below are the steps to activate policy caching for Endpoint Privilege Management for Unix and Linux (EPM-UL) , to convert clients to cached clients. These steps are specific to clients and not servers and can only be performed on on-premise versions of EPM-UL. The SaaS version (EPM-L) requires a full build on the clients if switching. Note: These steps cannot be performed on the SaaS version (EPM-L, this will result in a conflict error"{noformat}# rpm -Uv ./epml-cachedclient.x86_64.rpmerror: Failed dependencies:epml-client conflicts with epml-cachedclient-25.1.0.04-1.x86_64epml-cachedclient conflicts with (installed) epml-client-25.1.0.04-1.x86_64{noformat}"the non-cached client will need to be uninstalled and reinstalled as a cached client.  Warning: It is strongly recommended to test this in a non-production environment first.  Ensure the EPM-UL server is set to allow caching.  This can be confirmed by checking the /etc/pb.settings file .  R

Logging keypresses of unprivileged command line sessions

EPM-L and EPM-UL have extensive ability to log privilege access and sessions. You can use the pbsh and pbksh to log and record unprivileged session, however the problems with that are twofold. Firstly, the pb-shell environments are incompatible with Advanced Control and Audit rules, and secondly, the shell environments are out-of-date compared to modern shell environments. They lack modern features like command argument completion, wildcard completion, directory history stack and others due to their age. Maybe a modern shell environment like bash, zsh or fish will get integrated into the product.The first issue is easily taken care of by normal DAC file system permissions, they are unprivileged users after all. The second issue is more complex and could be solved by just forcing people to use pbksh, but there is a method of logging which is secure, and respects the users choice of shell. That is by using a combination of PAM (the Linux Pluggable Authentication Modules) and auditd.Audit

PMUL - Block all command without pbrun

Hi Team, I am trying PMUL and want to ask if i can block any standard command without pbrun. Example:I want to block the standard ping but without using pbrun ping.ping 8.8.8.8 should be rejected. But for now, i can only reject if user executed pbrun ping 8.8.8.8.Can we do that in PMUL? (right now, i am using role-based policies)I have a case from end-user, they want to block all kind of command except 2 or 3 specific commands.Thanks

Customer Success Quarterly - 2024-Q4 - Privilege Management Unix Linux

Hello! Last month our Chief Customer Officer, Sean Cashin, provided some information on our upcoming dedicated user community. I’m excited to announce that BeyondTrust launched our new BeeKeepers community on Monday, September 16th! Why BeeKeepers?The name BeeKeepers was born from the idea to protect and secure privileged identities, along with the paths those identities follow in order to gain privilege, aka Paths to Privilege. What does the BeeKeepers name mean to us?Imagine a company’s data and secrets as the honey in a beehive. BeeKeepers take care of the hive, protecting the honey and honeybees, from predators the live to steal the honey, damaging and destroying the hive. Now imagine you, BeyondTrust customers, IT Admins, SOC professionals, and CISOs are the BeeKeepers! And honeybees are identities – human and non-human – continuously travelling along their flight paths, the Paths to Privilege, collecting pollen and making more honey. BeeKeepers protect the honeybees’ path and con

PMUL Safe useradd functionality

One of the things that becomes a big issue for customers, especially when we move to automated build processes, is “how do you allow a user to add/remove users or groups, but NOT allow them to add ‘root-capable’ accounts, or elevate their own access?” As has been well discussed in other forums such as OWASP: https://cheatsheetseries.owasp.org/cheatsheets/Input_Validation_Cheat_Sheet.html - input validation is very difficult to do properly, especially if all you’re doing is checking “are these options included in the input?”  A lot of customers will simply try to grep the options for dangerous flags or mis-uses, but as documented above, this is not safe - a re-implementation of the commandline parsing is typically required for security.For a customer this month, we built a “pbuseradd” function that re-implements the “useradd” commandline validation, but adds protections such as “you cannot create a new backdoor root user”.  One of the features we use to validate these backdoors is the F

BeyondTrust Quarterly Update - 2024-Q3 - Privilege Management for Unix and Linux

Hello All,Leaning into the cliché, it’s hard to believe the year is half over already. As I'm sure is true for many of you, this has been a year of hard work and big changes at BeyondTrust. At the beginning of the year, I stepped into the role of Chief Customer Officer and welcomed both Mike Machado and Brett Thiess to the team as CISO and CMO, respectively. We also welcomed Ron Nissim and his team into the BeyondTrust family with the acquisition of Entitle, expanding BeyondTrust’s stance as an Identity Security leader! As the CCO, my passion and focus are on ensuring that our customers not only adopt but get real value from our products – securing their Identity landscape, minimizing the risk of threat actors, and limiting the blast radius of any incidents. Your thoughts and experiences are a key piece of guidance for us; from your NPS responses and feedback on your interactions with teams like support and services, to your engagement on changes we’ve made to products, we value the fe
