Red Canary is proud to announce Shell Activities capability for its MDR for Infrastructure solution. Shell Activities is a new way to filter, sort, and search through all commands run in shells across your cloud workloads.
What are shells and commands?
Shells allow you to run commands on Linux systems so that you can take actions such as opening and editing files, running scripts, or managing applications. Commands are human readable stand-ins for code or operations on Linux, turning a task like executing a script into a simple, single command (./). Commands and shells are powerful tools, not inherently malicious, and used by admins and others for legitimate reasons.
However, malicious actors can also use commands and shells to put your systems at risk. The same powerful tools used by your developers and administrators can allow malicious actors to exploit vulnerabilities, manipulate files and applications, and steal data.
Detecting threats with commands run in shells is a standard requirement for cloud workload protection products. However, displaying all commands run alongside the right context to investigate your data is unique to MDR for Infrastructure. We designed our new Shell Activities functionality to give you confidence and visibility into this part of development and security operations, offering admins a single view of all shell commands run across all workloads that are managed by MDR for Infrastructure.
Shell Activities at a glance
The Shell Activities feature builds on existing detection capabilities in MDR for Infrastructure that look at threats taking place in shells and associated with specific commands. MDR for Infrastructure already collects and alerts on malicious activity happening in shells. The new Shell Activities function takes this same command information and reports one month of all commands run in your workloads into a new Activities page of the Red Canary Portal.
Shell Activities offers a timeline view of each command alongside information about the user and workload, as well as the specific command run. You can search and filter by a wide range of metadata, including narrowing results to a specific time range, user, workload, or even arbitrary string or command.
Shell Activities brings benefits to both development leaders and security admins. On the DevOps side, Shell Activities provides instant visibility into shells and commands, while on the SecOps side, the feature offers a path for understanding and auditing shell behaviors.
Search by anything: Want to see every time someone used sudo? Want to see what happened leading up to an outage on Tuesday night at 7:34 PM? Need to see why 25 machines simultaneously restarted? Shell Activities enables you to instantly filter down and search commands so that you no longer have to skim audit logs or log into every machine to keep track of how users are interacting with your cloud workloads.
Put commands in context: Shell commands offer you a wealth of information about what is happening on your workloads and what activity might have led to a particular event. But without aggregation and searching, you are left to review logs by hand or guess at what ran. With Shell Activities, all of your shell commands are put in chronological order across your entire cloud, so that you can drill down by time, users, machines, and even commands to put events in context. Answering questions such as “what commands did this user run?” or “what was changed on this machine?” is now simple.
Look back in time: Look back through a month of shell commands to understand more about your workloads. With Shell Activities, you can look at a whole month of history or drill down to a specific day or time range to focus on exactly what you want. Records aren’t missed just because you didn’t check the machine in time.
Audit and understand user behavior: Why did 15 machines just restart all at once? Who pushed a patch to a server that led to downtime? Traditionally, these questions require your team to put in hours of effort searching for an answer. With Shell Activities, you can filter down to a particular machine or user and see exactly what was run and when.
Trust your tool: Shell Activities reports the same data MDR for Infrastructure sees to detect malicious activity in shells and shell commands. When you see data in Shell Activities, you can trust that your sensors are healthy and reporting back valuable data to generate the right detection outcomes.
Investigate incidents: Want to learn more about a detection or security event? Drill down to a particular time range or workload to replay any commands run, so that you can learn more about what led to a security event and provide additional forensic context without the need to pull logs or raw telemetry.
Red Canary CWP Shell Activities is now available for any current or future Red Canary customer on an Enterprise or Managed plan. Just head to Activities in your portal to get instant access to all shell commands run in your CWP-supported workloads over the last month.
