RE: [ActiveDir] OT: DNS entry

[Marcus.Oh]

I’ve been looking to do this too… but specifically for records w/out a TTL.  In other words, I want to capture static records only since dynamic will constantly change.  Any ideas?   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Monday, August 07, 2006 9:35 AM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] OT: DNS entry     Neil,   Are there any risks by carrying out your change listed below or is it a straight forward procedure. [Neil Ruston] The steps merely add SACL entries to DNS objects - that will certainly result in more security events and a slight overhead on the DCs but you need to weigh that against the risk of *not* auditing this type of change. As usual, it depends upon your environment and your requirements.    I don't think I have this enabled, if I do would that mean in the future if a DNS record is deleted this can be traced? [Neil Ruston] Yes, if the zone is stored in AD.    We use MOM here, is this something I could use? [Neil Ruston] MOM is aimed at systems monitoring whilst this thread deals with security monitoring. MS don't have an app in that space (yet) altho other vendors do. NetPro, NetIQ and Quest are the usual suspects here. These vendors offer tools that help with tracing changes (or 'forensic analysis', to use the correct parlance :)   thanks   Jim [EMAIL PROTECTED] wrote: That's a huge subject, a useful link is here: http://www.microsoft.com/technet/prodtechnol/windows2000serv/technologies/activedirectory/maintain/bpguide/part1/adsecp1.mspx   I'll give steps to audit DNS objects:   using adsiedit 1. Navigate to CN=MicrosoftDNS,CN=System (in the domain NC) 2. Right click, choose Properties, then select the Security tab and click Advanced 3. Select the Auditing tab 4. Click Add... and add group Everyone 5. Select "Apply onto" and choose "dnsZone objects" 6. Select 'Write all properties' Failed and 'Write all properties' Success 7. Click OK 8. Repeat steps 4 to 7 for object type dnsNode 9. Click OK, OK to close property sheets   The above will audit all writes to zone objects and DNS records which are stored in AD itself.   As stated previously, if the zones are stored as text files, then there is little that can be audited.   hth, neil From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of HBooGz Sent: 05 August 2006 06:25 To: ActiveDir@mail.activedir.org Subject: Re: [ActiveDir] OT: DNS entry hey guys,   could you point me to an article on how to setup audting for dns modifications and overall domain auditing ?   i've done auditing on the desktop level, just wondering whats changed..     On 8/4/06, Paul Williams <[EMAIL PROTECTED]> wrote: If you've got the necessary auditing enabled in your domain, and you had auditing ACEs configured on the DNS zone (location depends, generally you'd set it on CN=MicrosoftDNS folder) then yes, you can.  But you'll have to search each DCs security event log for this info.   Otherwise, you can't get this info.  You can check the whenChanged attribute on the tombstoned record for a rough idea of when the deletion occurred and try and move from there by looking at logon events, again if you have auditing enabled.   If you're not using AD-Integrated DNS, then none of the above will really help.     --Paul ----- Original Message ----- From: James Carter To: ActiveDir@mail.activedir.org Sent: Friday, August 04, 2006 12:09 PM Subject: [ActiveDir] OT: DNS entry     We had a static Server DNS entry deleted over the weekend.   Is there anyway to find out who deleted this entry?
