Accelerated Patch Management for Critical Infrastructure
Reduce your mean time to patch and risk
Keeping secure the Linux infrastructure used by critical infrastructure designated organizations is a very challenging task. Vulnerability patches need to be applied on time to comply with the security requirements, while the systems must remain up and running. Reduce your vulnerability patching time and associated risk by taking advantage of automation using the Live Patching technologies by TuxCare.
Reduce Your Vulnerability Exploitation Window with Automation
In large organizations, the separation of duties and different system ownership make security patching a challenging task. According to Ponemon Institute, 56% of enterprise organizations take from five weeks to more than one year to apply security patches. At the same time, high risk vulnerabilities appear at unexpected times. Instead of spending time identifying the responsible teams and deliberating on patching and restarting the vulnerable servers during the next maintenance window, live patching enables you to patch systems immediately – and automatically, shrinking the vulnerability patching window to the absolute minimum. Any vulnerable servers are patched as soon as the fix is available.
Patch Remote Systems Reliably and Efficiently
Many organizations have settled for expensive quarterly maintenance windows where patches are applied and servers are rebooted. That process ensures the latest vulnerability fixes are applied, but at the cost of in-person presence at the remote systems. Eliminate costly processes and maintenance windows or set them to what makes sense for your business, whether it is 12 months apart, or after several years of uptime. All while live patching vulnerabilities. Our customers have kept their systems running for more than 8 years with zero downtime and all impactful vulnerability patches have been applied.
Avoid Lengthy Risk Analysis with Wide Vulnerability Coverage
Security and compliance teams often communicate the vulnerability risk in terms of CVE lists in spreadsheets. Given the size of these lists for a modern operating system it is often prohibitive to make a detailed risk analysis for each listed CVE and the risk values do not consider your environment.
Instead of spending time analyzing the right impact of each vulnerability, or communicating your concerns back to the team, patch all the impactful vulnerabilities available of your Linux kernel and critical userspace components using live patching. That includes all known vulnerabilities with available fixes irrespective of severity. Avoid any lengthy vulnerability analysis and false alarms.
How Does Live Patching Reduce my Mean Time to Patch?
Operating systems vendors often assume that system updates are followed by a server restart
And often mix security updates with feature updates that may cause unexpected software behavior changes
Due to that, the operations teams deploy updates, including security fixes in monthly or quarterly batches to safeguard operations
Meaning that most of the times the exploitation vulnerability window will be large
TuxCare’s accelerated patch management only patches security vulnerabilities, eliminating the risk of malfunction by not including feature updates
Remediate Detected Vulnerabilities with Automated Patch Management
Although there is high complexity in implementing a cybersecurity framework, it comes up to a few simple notions. Notions like knowing what you have, configuring it in a secure way and establishing an automated patch management process. Live patching enables you in the latter, and in particular with continuous vulnerability patching, protecting from every vulnerability that poses a threat of exploitation, regardless of CVSS score. Whether you are targeting to comply with NIST cybersecurity framework, CIS controls, ISO27001 or SOC 2, TuxCare’s Accelerated patch management is here to enable your compliance.
Control
Dedicated ePortal server that runs inside your firewall lets you decide how and what patches are rolled out across your organization.
Integration
Flawless interoperability with automation tools, vulnerability scanners and cloud infrastructure monitoring services including Nessus, Qualys, Rapid7, Puppet, Ansible, Chef, Datadog, Tanium and Crowdstrike.
Cut Down Time on Mitigating Risks Due to OS Vulnerabilities
All vulnerabilities that pose a threat of exploitation are patched, regardless of CVSS score.
Vulnerabilities are patched automatically, requiring no system access or planned reboots.
Your vulnerability reports from all major vulnerability scanners and monitoring tools, show the actual patching status.
Spend time where you’re needed most; no documentation or mitigation is necessary for what is already patched!
Linux Live Patching Overview
When a vulnerability is discovered, we prepare a live patch for the Linux kernel or the affected userspace components. Once the resulting live patch passes our rigorous internal testing process, it is distributed to the TuxCare customers’ systems. When they receive the live patch, it is loaded by a special kernel module. The module detects when the old vulnerable code is not in use and then it momentarily pauses the kernel and replaces the old code with the new non-vulnerable code.
