A hostname in one tool. An IP address in another. A third record with the right OS version and the wrong owner. All three are the same server, and your inventory says you have three.
Servers are usually the best-instrumented things you own, and that is exactly the problem: every tool has an opinion about them, and the opinions disagree. Reconciliation is the unglamorous work of deciding which one is true and folding the rest into it. Eleventh of fourteen, and the least exciting use case in the series — which is probably why it stays broken.
You’ll end up with fewer servers than your tools claim. That’s the point.
The Server Management Challenge
Servers are the backbone of any organization’s IT infrastructure.
Whether on-premises or in the cloud, Windows and Linux servers host critical business applications and often process sensitive data.
Maintaining an accurate inventory of these servers, including their operating systems, versions, resources, configurations, installed software, and associated users, is crucial for protecting your organization’s infrastructure.
Server Administration Challenges
Managing servers and their operating systems comes with several challenges.
Not addressing these challenges is leaving the proverbial door open to bad actors.
- Outdated operating systems: Servers running outdated OS versions are vulnerable to attacks.
- Misconfigured servers: Improperly configured servers can open security gaps in your network.
- Resource management: Lack of insight into server resources (RAM, hard drive space) can lead to performance issues.
- Diverse environments: Managing servers across on-premises and multiple cloud platforms adds complexity.
Enter SJULTRA's Cybersecurity Observability Service
This is where SJULTRA’s CAASM services, becomes your incident response nitrous boost.
It’s like giving your security team a time machine and a crystal ball, all rolled into one.
CAASM pulls data from a smorgasbord of sources:
- Endpoint Agents
- Configuration and Patch Management Tools
- Ticketing & Helpdesk Platforms
- Networking Tools
- Vulnerability Assessment Tools
- IAM Solutions
- Cloud Infrastructure
By correlating this data, CAASM creates a rich, unified view of your entire digital ecosystem. It’s like having a digital map of your entire IT landscape, with every device, user, and cloud instance clearly labeled.
Technical Deep Dive
Let’s explore how to use SJULTRA CAASM to manage your Windows and Linux servers:
Connect Data Sources
Start by connecting to key data sources such as:
- Cloud Infrastructure platforms
- Infrastructure Monitoring tools
- Networking monitoring systems
- MDM/EMM solutions
- EDR/EPP tools
- Configuration/Patch Management systems
- ITAM/ITSM platforms
- Vulnerability Analysis (VA) tools
- IAM solutions
- UEM platforms
- Virtualization monitoring tools
Track operating systems and versions
There are a couple of steps to this.
First, create a chart of known operating systems from your data sources — let’s see what you’ve got!
Second, use the CAASM Query Wizard to create targeted queries such as “Find all Linux servers and their distributions”
To start focusing on Linux and Windows, you can create a new query and a new chart for that.
For example, this query and chart combination will first find all your Windows serers:
Then you can create a chart based on that query:
Monitor Server Resources
Create queries to track server resources.
Add columns for Total RAM, Free RAM, Hard Drives: Size, and Hard Drives: Free Size to your query results.
Now, based on your query… and then your chart… you can quickly see server resources across your whole estate in one place.
Identify Servers with Critical vulnerabilities
Find servers with critical vulnerabilities:
Identify servers with no vulnerability software
Identify servers without vulnerability assessment tools:
Identify Installed Software and Agent Versions
This level of detail is particularly useful when you need to quickly find if you are exposed to X threat on Y software.
For example, threats can apply to only specific product versions so being able to quickly find if you have that version is key to accelerating incident response.
Taking action with CAASM enforcement actions
Once you’ve identified issues or discrepancies in your server inventory, SJULTRA CAASM allows you to take immediate action:
- Send notifications to preferred platforms (e.g., email, Slack) about critical issues.
- Create helpdesk tickets in ServiceNow, Zendesk, or Jira for follow-up actions.
- Enrich device data with custom tags or third-party sources like Shodan or Censys.
- Update vulnerability scans on specific servers.
- Deploy files or run custom commands on servers requiring attention.
- Isolate or unisolate devices from the network in case of security incidents.
Summary
Maintaing a Windows and Linux server inventory — that is accurate, credible, comprehensive — is crucial for maintaining a robust and secure IT infrastructure.
With SJULTRA CAASM, you can transform this challenging task into a streamlined, automated process.
Remember, this is just one of the 14 powerful use cases for CAASM. Stay tuned for our next installment to discover more ways to enhance your cybersecurity posture.
