Thing | I am taking over the maintenance of a small network of 20 workstations and one server. One of the first things I did was scan the server, which is connected directly to the Internet. Here is the result of that scan: [code]53/tcp open domain 88/tcp open kerberos-sec 111/tcp open sunrpc 135/tcp filtered loc-srv 136/tcp filtered profile 137/tcp filtered netbios-ns 138/tcp filtered netbios-dgm 139/tcp filtered netbios-ssn 389/tcp open ldap 445/tcp filtered microsoft-ds 464/tcp open kpasswd5 593/tcp open http-rpc-epmap 636/tcp open ldapssl 1026/tcp open LSA-or-nterm 1029/tcp open ms-lsa 1103/tcp open xaudio 1401/tcp open goldleaf-licman 3268/tcp open globalcatLDAP 3269/tcp open globalcatLDAPssl 3372/tcp open msdtc 3389/tcp open ms-term-serv 5800/tcp open vnc-http 5900/tcp open vnc Nmap run completed -- 1 IP address (1 host up) scanned in 10 seconds[/code] I shouldn't need to tell you that I'm going there today and put it behind a firewall, but I will anyway. I know what some of this stuff is but I am clueless as to what some of it is and how to turn it off. Your input is appreciated. Don't bust my balls about not knowing much about Winders security. /edit/The only things that needs to be running are Term Server and VNC. | May 23, 2003, 2:02 PM |
CupHead | Oh goodness, and that's a windows machine. I suggest going through the list of Services (Control Panel -> Administrative Tools -> Computer Management -> Click on the Services Tree Node) and finding the corresponding services to each of those open ports. I suspect the majority will be named similarly to the port description and that the rest will be easily identified by other people who read the thread. | May 23, 2003, 2:15 PM |
Yoni | Sysinternals makes a tool called TCPView. It can help you associate an open port (or a connection) with a process (something that Windows' netstat lacks). Process Explorer might come in handy as well. | May 23, 2003, 2:59 PM |
Raven | Don't forget EtherPeek! Ofcourse, you'll need to download a happy version of Ether Peek, even though for your purposes, the trial version should work decently also. | May 23, 2003, 9:24 PM |
Thing | Ehh I didn't get to mess with it today. I was too busy fixing the screwed up printing setup. Maybe next week. | May 24, 2003, 3:05 AM |
