![]() Yes, below solution is not in best practice, but a temporary workaround until you get Cisco ACS or ISE solution. Here is a second round to address the issue. It would be the problem since Tenable / Security Center will execute “show running-config” command instead of the special(hidden command)Īgain, ACS 5.x will be handy to prohibit and permit certain Cisco commands One catch from this method is “show running-config” need to be changed with “show running-config view full” in order for viewing entire running configuration. You must have sufficient permissions needed to run a show running-config all command. Credentials The plugin requires SSH credentials for online scanning. The phrases Policy Compliance and Compliance Checks are used interchangeably within this document. Cisco Firepower Scan Requirements (Tenable Nessus Compliance Checks) Compliance Checks Reference: Compliance Check Types > A-E > Cisco Firepower > Scan Requirements Cisco Firepower Scan Requirements The following describes scan requirements when using the Cisco Firepower plugin. It does not require or support any escalation method. This document describes how Nessus 5.x can be used to audit the configuration of Unix, Windows, database, SCADA, IBM iSeries, and Cisco systems against a compliance policy as well as search the contents of various systems for sensitive content. The plugin requires SSH credentials for online scanning. The host's local NAC Appliance Server is responsible for. The following describes scan requirements when using the Cisco ACI plugin. The new credential will provide all ” show + commands “, but no write memory. If network scans (Nessus scans) are configured for the user's role, they are now performed. Privilege exec all level 7 show running-config Username NESSUS privilege 7 secret Abcd12345 Username NESSUS privilege 3 password Abcd12345 If you don’t have Cisco ACS server, try the following way to achieve the goal. If you have Cisco ACS (TACACS+) server, it would be easy to control permitted commands with the dedicated user account for the Nessus scanner. Unix, Linux, Windows, Cisco, etc Understanding of common protocols. So, now we know what commands that Nessus use for the vulnerability and compliance scanning. Nessus 176483 Changelog Version 1.1 Cisco Identity Services Engine Command Injection Vulnerability (cisco-sa-ise-injection-sRQnsEU9) high Nessus Plugin ID 176483 Language: English Version 1.1 May 31, 2023, 7:18 AM CVSS temporal metrics ('CVSSv2 temporal vector' set to 'CVSS2E:U/RL:OF/RC:C'. e.g., Tenable Nessus, Qualys VM, OSS enumeration tools Demonstrate hands on. Nessus supports three types of authentication methods for use with SSH: username and password, public/private keys, and Kerberos. Careful, they put together of all commands of Cisco router, switch and ASA in a single spreadsheet. Nessus uses Secure Shell (SSH) for credentialed scans on Cisco devices. There are a number of approaches to creating Nessus scanning policies.Once you open it, you will see the whole list of Cisco commands. To perform this scan an IOS user with privilege 1 is sufficient. ![]() You may be running "IP Base" set which doesn't support MPLS but Nessus will show MPLS vulnerability. For example if there is a vulnerability in http server but your device doesn't have it enabled you are not vulnerable. Furthermore there are different feature sets of the same IOS version. to include Cisco IOS, VLAN segmentation, Network Access Control (802.1x). ![]() You may be running version of IOS that has known vulnerabilities but your device may not be vulnerable. Experience with Assured Compliance Assessment Solution (ACAS/NESSUS). Checks can be performed via a non-privileged login or a login that uses the privileged enable password. Third: our policy will include checks for IOS, CatOS and Linksys devices.įourth: Probably the most important one. Nessus can test the running configuration for systems running the Cisco IOS operating system and confirm that it is in accordance with security policy standards. Second: Nessus supports only SSH authentication for Cisco devices. 5 Cisco ISE Identity Engine 1.3 Configuration. You can export to the list of IPs from CiscoWorks or use NMAP scan and import result to Nessus. Tenable Nessus and Cisco Identity Service Integration SECURE ACCESS HOW-TO GUIDES Table of Contents About. ![]() The reason for that is that someone could set up a rogue SSH server and intercept the credential you use for scanning. There are a few caveats to scanning Cisco switches with Nessus.įirst: I recommend scanning only specific management IP addresses of devices rather than network ranges.
