Check for windows administrative vulnerabilities

Did you add rules for SSH? Did you change rules in the firewall to support VPN? Are these changes still needed? Could they be set up differently and more securely? Rather than opening a static port in the firewall, could it be set up with a firewall rule that reviews and scans the traffic instead?

If you need guidance, ask your firewall vendor support department for assistance. Firewall rules in various platforms can be confusing or complicated to set up. Review what changes were made to users in new organizational permissions groups. Are they still appropriate? Forum user Doc used log4j2-scan to write a shell script for CVE vulnerability scanning and mitigation patching for Linux servers:.

Please keep in mind to place the script and log4j2-scan bin tested with v1. Be aware to insert the current version of the binaries log4j-scan AND log4j2-scan. The binaries can be found on the GitHub repo of Logpresso. If you want to identify vulnerable Windows systems you can also easily do this with a local check. With both scripts, Checkmk can help you to quickly track down all systems that are vulnerable to the Log4Shell exploit. Based on the work of Doc, thl-cmk , adopted the Windows script for the latest version of log4j2-scan.

The binary for the script log4j2-scan. Now the check should work and you can detect Log4j on Windows servers in your infrastructure. In the Checkmk Community the Spanish user a was one of the first members, who shared such a script for Checkmk to track down the Log4j2 libraries in the IT infrastructure in our forum. If you are interested into the conversation check out the topic in our forum.

The script scans all systems for potentially affected. A detailed guide on how to roll out local checks on your systems to detect Log4j2 modules on Windows servers or Linux systems can be read in detail in our documentation. In this way, it is possible to detect vulnerable Log4j libraries on Windows and Linux systems in your infrastructure and to customize the time series data for the service in Checkmk.

You can download the plugin as MKP here. After downloading it can be rolled out on the target system s for Checkmk Enterprise Edition users via the Agent Bakery. MBSA provides a report on the findings for each scan. Reports include information on any issues that are found and also provide instructions on how to fix any of the issues.

It uses Windows Management Instrumentation queries to inspect the system for the following vulnerabilities: Check for Windows Administrative Vulnerabilities MBSA inspects the system for basic security issues such as whether more than one user is a member of the Administrators group, the Guest account is enabled it should be disabled , NTFS is used on all the drives, and any folders are being shared. The security updates check gives you several additional options, including these: Configure Computers for Microsoft Update And Scanning Prerequisites If a client doesn't have the Windows Update Agent installed, it can't be scanned.

Figure 7. Even if the release of a new version of an application is known, it is often ignored, so this is where Secunia Personal Software Inspector comes in.

Secunia PSI is a free application for security scanning. It checks out which applications need to be updated and is also capable of automating the process of updating. The application can run in the background and identify the programs that need updating, and download the appropriate patch and install it, without much user interaction.

If it is not capable of updating the application itself, it notifies the user about it and also provides some instructions that can be helpful in the process. Figure 8 shows the output of Secunia PSI for a windows machine. Secunia PSI performs its functionality by examining the files on the computer and extracting software vendor specific metadata.

By allowing scanning for all the updates through one interface and automating the process of updating, it substantially reduces the effort required for keeping the system updated and increases the security level.

Figure 9 displays the Secunia PSI interface after updating the specific application. It scans a machine for vulnerabilities and displays the result in the form of a list. Along with the vulnerabilities it also provides the rating of the vulnerabilities and a link to the appropriate Microsoft patch Microsoft Security Bulletin.

It is a simple program which requires no installation and executes by simply double-clicking the Winvulscan. Windows Sysinternals: Windows Sysinternals is actually not a vulnerability scanner, but it is capable of assisting users with its various functionalities. It is a collection of utilities which can help to manage, diagnose, troubleshoot and monitor a Windows machine. The utilities of Sysinternals have been bundled together into a single suite, the Sysinternals suite.
