----------------------------------------------------------------------- VENEv = Volker's & Enno's Nessus EValuation http://www.wyae.de/software/vonev/ ----------------------------------------------------------------------- The Nessus security scanner by http://www.tenablesecurity.com/ is a valuable tool for security consultants performing network audits. Unfortunately it does lack a quick overview over the vulnerabilities (supposedly) found. This tool will extract such a re-sortable overview as CSV table from a Nessus HTML export. Requirements: ------------- * Perl * Nessus .NESSUS export of version 4.2 or newer * a (Unix) shell Usage: ------ Usage: venev.pl [Options] [MULTI files] *.nessus > nessus.csv Options: --stats|-s Output vulnerabilities per host --vstats|-v Output host stats in verbose form with additional information (implies --all, see below) --all|-a Output all findings - otherwise, bogus findings like scan information are supressed) (useful for stats) --noexcel|-n Leave away Excel quirks, use proper CSV --csvsep|-c Use as CSV separator --help|-h This help Output format (semicolon separated): Count ; Finding ; Nessus-ID ; Risk ; Severity ; CVSS/ CVE ; BID ; Other ref. ; IPs Output format stats (vulnerabilities per host, semicolon separated): Host ; Max_Severity ; Critical ; High ; Medium ; Low Output format verbose stats (vulnerabilities per host, semicolon separated): HostIP ; HostReverseLookup ; OS ; Ports ; Max_Severity ; Critical ; High ; Medium ; Low MULTI files: Must start with "#MULTI" to be recognized MULTI files list multi-homed hosts. Each line lists all IP addresses (space separated) of one host. Only the first IP address will be used in the report for all reported vulnerabilities. Example: #MULTI 127.0.0.1 127.0.0.2 127.0.0.3 You can import te CSV tables into your favourite spreadsheet application, e.g. LibreOffice, Gnumeric, KOffice or MS-Office and re-sort and filter ad gusto. Evaluation: ----------- Each finding will be documented twice in the CSV table. First you will find each single finding for each single IP with a count number of -9999. After all single findungs are listed, all findings are listed again summed up per finding. Thus you get a table similar to this (abridged) one: -9999 Finding-AAA 10.1.1.2 -9999 Finding-AAA 10.1.1.3 -9999 Finding-AAA 10.1.1.4 -9999 Finding-B 10.1.1.4 -9999 Finding-CCCCC 10.1.1.4 -9999 Finding-AAA 10.1.1.5 -9999 Finding-CCCCC 10.1.1.5 4 Finding-AAA 10.1.1.2, 10.1.1.3, 10.1.1.4, 10.1.1.5, 1 Finding-B 10.1.1.4, 2 Finding-CCCCC 10.1.1.4, 10.1.1.5, The "-9999" rows are ideal for GREPping, while the summary lines are ideal for a fast overview, for example: - Import the CSV into your spreadsheet - Sort by CVSS (this is the severity value set by Nessus) - Set filter: only show rows with count > 0 - Done. Beware: Nessus results (and thus the ones of this tool) are a to be taken with a serious grain of salt. Don't trust them blindly but verify. Nessus is "only" a tool, a useful one, but not always a reliable one. Use Nessus (like NMAP or other scanners) for the brainless grunt work and start working. If you need a security consultant to check your network, systems or architecture, or to help you with a security problem/incident or (a better approach) check your security architecture and risks, simply contact me. ;-) --------------------------------------------------------------- VENEv = Volkers & Enno's Nessus EValuation 2008- by Volker Tanger & Enno Ewers All rights reserved.
