3 Hoofdstuk!1!Achtergrond! 1.1!Inleiding! De IT infrastructuur van <organisatie> nagelopen middels een beveiligingsscan. Doelstelling van deze beveiligingsscan is het vaststellen van de effectiviteit van de beveiliging van het netwerk en de hieraan gekoppelde systemen van <organisatie>. Onderzocht werd of er zwakheden in de beveiliging zijn waardoor het mogelijk is om toegang te krijgen tot het netwerk, de aangesloten systemen en/of gegevens. De resultaten van deze beveiligingsscan zijn in dit rapport weergegeven. 1.2!Structuur!rapportage! In de rapportage komen achtereenvolgens aan de orde: Werkwijze en randvoorwaarden; Management samenvatting, met daarin onze conclusie, belangrijkste bevindingen en acties; Bijlagen: onze gedetailleerde, technische informatie van de uitgevoerde scan. 1.3!Werkwijze!en!randvoorwaarden! Doel van deze kwetsbaarhedenscan is om na te gaan of de geselecteerde onderdelen qua beveiliging op voldoende niveau zijn om de, door <organisatie>, gewenste dienstverlening aan haar eigen organisatie en haar klanten op verantwoorde wijze te kunnen aanbieden.! De volgende scan is uitgevoerd: Toegang zonder inloggegevens vanaf internet Dit scenario toont aan welke systemen vanaf Internet te benaderen zijn en of er kwetsbaarheden zijn die het mogelijk maken toegang te verkrijgen zonder gebruikmaking van vooraf verstrekte inloggegevens.! De omvang van de securitytest is beperkt tot: de systemen die vanaf het internet toegankelijk zijn via de IP-adressen <vb iprange> t/m <vb iprange>. de webservers die toegangkelijk zijn via de URL s: /8

4 De scan is uitgevoerd in de periode <datum>. Deze rapportage kan zonder voorafgaande toestemming van KoutersVanderMeer niet aan derden (buiten <organisatie> en SRA) worden verstrekt.! 4/8

5 Hoofdstuk!2!Management!Samenvatting! De systemen van uw organisatie zijn vanaf Internet gescand op mogelijke kwetsbaarheden. Verdeeld over de twee actieve systemen zijn hierbij vijf kwetsbaarheden aangetroffen met een gemiddeld risico die van invloed kunnen zijn op de beschikbaarheid, vertrouwelijkheid en integriteit van de gegevens en systemen. De overige bevindingen betreffen informatieve meldingen of kwetsbaarheden met een zeer beperkt risico. Het beveiligingsniveau van uw omgeving zoals bereikbaar vanaf Internet is door ons beoordeeld als redelijk. De voornaamste oorzaken van de aangetroffen kwetsbaarheden zijn: niveau van beveiligde netwerkverbindingen niet sterk. inloggegevens bij het versturen van zijn afluisterbaar. Figuur 1: Overzicht risico s externe systemen 5/8

6 Figuur 2: Overzicht impact externe systemen De noemenswaardige bevindingen zijn hieronder weergegeven met bijbehorende acties en actiehouder: Niveau van beveiligde netwerkverbindingen niet sterk Bevinding: Voor het beveiligen van netwerkverbindingen naar o.a. webservers wordt de techniek Secure Socket Layer (SSL) gebruikt. Deze techniek maakt gebruik van encryptiesleutels die verschillende lengtes kunnen hebben. Een langere sleutel is sterker. Het systeem <ipadres> (www.<organisatie>.nl en webmail.<organisatie>.nl) staat het gebruik van niet-sterke encryptiesleutels toe dat afluisteren en manipulatie van gegevens mogelijk maakt. Daarnaast maakt dit systeem onder andere gebruik van SSL versie 2. Deze versie staat bekend als onveilig. Actie: o Configureer SSL zodat uitsluitend het gebruik van sterke encryptiesleutels mogelijk is. o Schakel SSL versie 2 uit.!! Actiehouder: <IT Beheerder> 6/8

7 Inloggegevens bij het versturen van zijn afluisterbaar! Bevinding: Het systeem <ipadres> biedt de mogelijkheid aan gebruikers om te versturen mits er eerst wordt ingelogd. Het inloggen kan echter worden gedaan zonder dat de inloggegevens zijn beveiligd tegen afluisteren. Hiermee kan, door onbevoegden, ongewenst worden inlogd op één of meerdere systemen. Actie: o Heroverweeg de noodzaak van deze functionaliteit. Indien niet nodig: schakel deze functionaliteit uit. o Configureer de service zodat inloggen uitsluitend op een goed beveiligde methode kan. Actiehouder: <organisatie> Voor onze gedetailleerde bevindingen en bijbehorende acties verwijzen wij naar de bijlage. Daarin is als extra achtergrondinformatie de gedetailleerde technische rapportage van de kwetsbaarhedenscan opgenomen. Tot het geven van een persoonlijke toelichting zijn wij gaarne bereid.! 7/8

12 Laag Risico ICMP Timestamp Request The remote host answers to an ICMP timestamp request. This allows an attacker to know the time and date on your host. Filter out the ICMP timestamp requests (type 13) and replies (type 14). * HP-UX Disable ICMP timestamp responses on HP/UX Execute the following command: ndd -set /dev/ip ip_respond_to_timestamp_broadcast 0 The easiest and most effective solution is to configure your firewall to block incoming and outgoing ICMP packets with ICMP types 13 (timestamp request) and 14 (timestamp response). * Cisco IOS Disable ICMP timestamp responses on Cisco IOS Use ACLs to block ICMP types 13 and 14. For example: deny icmp any any 13 deny icmp any any 14 Note that it is generally preferable to use ACLs that block everything by default and then selectively allow certain types of traffic in. For example, block everything and then only allow ICMP unreachable, ICMP echo reply, ICMP time exceeded, and ICMP source quench: permit icmp any any unreachable permit icmp any any echo-reply permit icmp any any time-exceeded permit icmp any any source-quench The easiest and most effective solution is to configure your firewall to block incoming and outgoing ICMP packets with ICMP types 13 (timestamp request) and 14 (timestamp response). * SGI Irix Disable ICMP timestamp responses on SGI Irix IRIX does not offer a way to disable ICMP timestamp responses. Therefore, you should block ICMP on the affected host using ipfilterd, and/or block it at any external firewalls. The easiest and most effective solution is to configure your firewall to block incoming and outgoing ICMP packets with ICMP types 13 (timestamp request) and 14 (timestamp response). * Linux Disable ICMP timestamp responses on Linux Linux offers neither a sysctl nor a /proc/sys/net/ipv4 interface to disable ICMP timestamp responses. Therefore, you should block ICMP on the affected host using iptables, and/or block it at the firewall. For example: ipchains -A input -p icmp --icmp-type timestamp-request -j DROP ipchains -A output -p icmp --icmp-type timestamp-reply -j DROP The easiest and most effective solution is to configure your firewall to block incoming and outgoing ICMP packets with ICMP types 13 (timestamp request) and 14 (timestamp response). * Microsoft Windows NT, Microsoft Windows NT Workstation, Microsoft Windows NT Server, Microsoft Windows NT Advanced Server, Microsoft Windows NT Server, Enterprise Edition, Microsoft Windows NT Server, Terminal Server Edition Disable ICMP timestamp responses on Windows NT 4 Windows NT 4 does not provide a way to block ICMP packets. Therefore, you should block them at the firewall. The easiest and most effective solution is to configure your firewall to block incoming and outgoing ICMP packets with ICMP types 13 (timestamp request) and 14 (timestamp response). * OpenBSD Disable ICMP timestamp responses on OpenBSD Set the "net.inet.icmp.tstamprepl" sysctl variable to 0. sysctl -w net.inet.icmp.tstamprepl=0 The easiest and most effective solution is to configure your firewall to block incoming and outgoing ICMP packets with ICMP types 13 (timestamp request) and 14 (timestamp response). * Cisco PIX Disable ICMP timestamp responses on Cisco PIX A properly configured PIX firewall should never respond to ICMP packets on its external interface. In PIX Software versions 4.1(6) until 5.2.1, ICMP traffic to the PIX's internal interface is permitted; the PIX cannot be configured to NOT respond. Beginning in PIX Software version 5.2.1, ICMP is still permitted on the internal interface by default, but ICMP responses from its internal interfaces can be disabled with the icmp command, as follows, where is the name of the internal interface: icmp deny any 13

13 icmp deny any 14 Don't forget to save the configuration when you are finished. See Cisco's support document Handling ICMP Pings with the PIX Firewall for more information. The easiest and most effective solution is to configure your firewall to block incoming and outgoing ICMP packets with ICMP types 13 (timestamp request) and 14 (timestamp response). * Sun Solaris Disable ICMP timestamp responses on Solaris Execute the following commands: /usr/sbin/ndd -set /dev/ip ip_respond_to_timestamp 0 /usr/sbin/ndd -set /dev/ip ip_respond_to_timestamp_broadcast 0 The easiest and most effective solution is to configure your firewall to block incoming and outgoing ICMP packets with ICMP types 13 (timestamp request) and 14 (timestamp response). * Microsoft Windows 2000, Microsoft Windows 2000 Professional, Microsoft Windows 2000 Server, Microsoft Windows 2000 Advanced Server, Microsoft Windows 2000 Datacenter Server Disable ICMP timestamp responses on Windows 2000 Use the IPSec filter feature to define an apply an IP filter list that blocks ICMP types 13 and 14. Note that the standard TCP/IP blocking capability under the "Networking and Dialup Connections" control panel is NOT capable of blocking ICMP (only TCP and UDP). The IPSec filter features, while they may seem strictly related to the IPSec standards, will allow you to selectively block these ICMP packets. See for more information. The easiest and most effective solution is to configure your firewall to block incoming and outgoing ICMP packets with ICMP types 13 (timestamp request) and 14 (timestamp response). * Microsoft Windows XP, Microsoft Windows XP Home, Microsoft Windows XP Professional, Microsoft Windows Server 2003, Microsoft Windows Server 2003, Standard Edition, Microsoft Windows Server 2003, Enterprise Edition, Microsoft Windows Server 2003, Datacenter Edition, Microsoft Windows Server 2003, Web Edition, Microsoft Windows Small Business Server 2003 Disable ICMP timestamp responses on Windows XP/2K3 ICMP timestamp responses can be disabled by deselecting the "allow incoming timestamp request" option in the ICMP configuration panel of Windows Firewall. Go to the Network Connections control panel. Right click on the network adapter and select "properties", or select the internet adapter and Select File->Properties. Select the "Advanced" tab. In the Windows Firewall box, select "Settings". Select the "General" tab. Enable the firewall by selecting the "on (recommended)" option. Select the "Advanced" tab. In the ICMP box, select "Settings". Deselect (uncheck) the "Allow incoming timestamp request" option. Select "OK" to exit the ICMP Settings dialog and save the settings. Select "OK" to exit the Windows Firewall dialog and save the settings. Select "OK" to exit the internet adapter dialog. For more information, see: * Microsoft Windows Vista, Microsoft Windows Vista Home, Basic Edition, Microsoft Windows Vista Home, Basic N Edition, Microsoft Windows Vista Home, Premium Edition, Microsoft Windows Vista Ultimate Edition, Microsoft Windows Vista Enterprise Edition, Microsoft Windows Vista Business Edition, Microsoft Windows Vista Business N Edition, Microsoft Windows Vista Starter Edition, Microsoft Windows Server 2008, Microsoft Windows Server 2008 Standard Edition, Microsoft Windows Server 2008 Enterprise Edition, Microsoft Windows Server 2008 Datacenter Edition, Microsoft Windows Server 2008 HPC Edition, Microsoft Windows Server 2008 Web Edition, Microsoft Windows Server 2008 Storage Edition, Microsoft Windows Small Business Server 2008, Microsoft Windows Essential Business Server 2008 Disable ICMP timestamp responses on Windows Vista/2008 ICMP timestamp responses can be disabled via the netsh command line utility. Go to the Windows Control Panel. Select "Windows Firewall". In the Windows Firewall box, select "Change Settings". Enable the firewall by selecting the "on (recommended)" option. Open a Command Prompt.

14 Enter "netsh firewall set icmpsetting 13 disable" For more information, see: Disable ICMP timestamp responses Disable ICMP timestamp replies for the device. If the device does not support this level of configuration, the easiest and most effective solution is to configure your firewall to block incoming and outgoing ICMP packets with ICMP types 13 (timestamp request) and 14 (timestamp response). Laag Risico RPC Portmapper The RPC portmapper (portmap(8)) is a server that converts RPC program numbers into TCP/IP (or UDP/IP) protocol port numbers. If RPC services are not used on this machine, close this service. Otherwise filter traffic to this port to allow access only from trusted machines. Laag Risico rpcinfo -p Information Disclosure This test calls the DUMP RPC on the port mapper, to obtain the list of all registered programs. This is what we found: RPC program # version 4 'portmapper' (portmap sunrpc rpcbind) is running on this port RPC program # version 3 'portmapper' (portmap sunrpc rpcbind) is running on this port RPC program # version 2 'portmapper' (portmap sunrpc rpcbind) is running on this port RPC program # version 4 'portmapper' (portmap sunrpc rpcbind) is running on this port RPC program # version 3 'portmapper' (portmap sunrpc rpcbind) is running on this por t RPC program # version 2 'portmapper' (portmap sunrpc rpcbind) is running on this por t Laag Risico NTP Variables Reading It is possible to determine a lot of information about the remote host by querying the NTP variables - these include OS descriptor, and time settings. Theoretically one could work out the NTP peer relationships and track back network settings from this. Set NTP to restrict default access to ignore all info packets: restrict default ignore Laag Risico IMAP Service STARTTLS Command Support The remote IMAP service supports the use of the 'STARTTLS' command to switch from a plaintext to an encrypted communications channel.

15 Laag Risico SSH Server Backported Security Patches Security patches may have been 'back ported' to the remote SSH server without changing its version number. Bannerbased checks have been disabled to avoid false positives. Laag Risico Digit Services Detection This test is a complement of Service Detection. It tries to identifies services that return 3 ASCII digits codes (like FTP, SMTP, NNTP etc). Laag Risico SMTP Authentication Methods The remote SMTP server advertises that it supports authentication. The following authentication methods are advertised by the SMTP server without encryption: * LOGIN * PLAIN Review the list of methods and whether they're available over an encrypted channel. The following authentication methods are advertised by the SMTP server without encryption: * LOGIN * PLAIN Laag Risico Directory Scanner We found some common directories on the web server: The following directories were discovered: /cgi-bin, /error The following directories require authentication: /phpmyadmin Check if those directories contain any sensitive information, if they do, prevent unauthorized access to them. The following directories were discovered: /cgi-bin, /error The following directories require authentication: /phpmyadmin Laag Risico HTTP Packet Inspection This test gives some information about the remote HTTP protocol - the version used, whether HTTP Keep-Alive and HTTP pipelining are enabled, etc. Protocol version: HTTP/1.1 SSL: yes Pipelining: yes Keep-Alive: yes Options allowed: (Not implemented) Headers: Date: Wed, 28 Nov :20:00 GMT Server: Apache/2
