Ethical Hacking Discussions and Related Certifications / OS / CIS - Baseline\hardening doc
|

Hi all, I've been following the latest CIS hardening document for windows 7 and using Nessus to monitor my GPO progress. However I've come accross one setting which I don't seem to understand the logic of and wanted others opinion. If I have no legacy in my domain why would I do this? I can see you may want to add exceptions but this seems to be lowering security and seems to be saying just fall back on other security at the OS level??? Check Name: 1.12.4 Turn off Data Execution Prevention for Explorer Information
This control defines whether Data Execute Prevention (DEP) is enabled or disabled for the explorer process.
CCE-9918-4
ref: https://benchmarks.cisecurity.org/tools2/windows/CIS_Microsoft_Windows_7_Benchmark_v1.2.0.pdf pg. 160 Description: This control determines if Data Execute Prevention (DEP) is enabled or disabled for the explorer process. For all profiles, the recommended state for this setting is Disabled. Rationale: DEP, when deployed in concert with the other native Windows exploit mitigation such a ASLR, Guard Stack, and SafeSEH, provides an effective means for preventing the exploitation of certain software defects that may affect explorer.

Agree, I really want to get some accountability over these accounts and provide some ability of containment if the worst happens. At the moment its the old god complex going on and convinience rules over security, using things like password vaults which removes all accountability with RDP utils which store credentials to hop around boxes that seems to further flatten the need for priv escalation to that of a normal account.
I'm currently looking at the newer audit policies in 2008 as we run a windows 7 only shop (one good thing no legacy about) although expensive firewalls running as pure stateful packet filters was a bit of a laugh.
thanks for your input...

Ethical Hacking Discussions and Related Certifications / OS / Windows Token Misuse

Hi All,
just a quick question, I've recently found quite bad overuse of domain admin priv's accross our network by admins. I've performed a POC by using Incognito and successfully added a new account from a standard account into the domain admins via tokens.
I've read the paper for this, as included in unleashed\bt type materials. So I will be trying to implement better policy to control overuse and highlight the dangers to why Domain admins needs reducing.
I'm currently going through a best practise windows 7 hardening document and it mentions using User Account Control (UAC)
would this be a mitigation or risk reduction in an attack like incognito? My feelings are it could help remove the dash attitude of just logging in as admin and therefore reducing the amount of tokens hanging around.
Granted the real problem is a culture shift and AD structure\ least priv permissions themes, but its still useful.
Any opinions or experiences welcome...
thanks

Ethical Hacking Discussions and Related Certifications / General Certification / Prep for TIGER or CREST (Check)

Hi Guys, I've spent a lot of my time in infrastructure roles and picked up MCSE and CCNA along the way. I always found myself more interested in the security sections these work roles presented and found myself getting the infosec bug from books by Bruce Schneider and Kevin Mitnick to name just two. I then progressed by self studying the CEH and moved into a general IT security consultant role with a big firm. Again I carried on my knowledge by self-funding\studying CISSP and CISM and passing. I now feel that my work has become a little stale and find myself giving signature type incident\project answers on the risks to the business. So of late I've been thinking of specialising into a pentester role. I have to coordinate and review pentests at my current job and alarmingly had to step in once or twice when I've felt the pentest is creating unacceptable risks to the business (something some forget that's why we are here!) So I'm glad I've seen the wider picture here also! After some research I've seen that in the UK you have to get a cert that meets up with the CHECK standard. So that's TIGER or CREST for me being none government. Its not worth me progressing the LPT route in reality... Anyway given my background I've decided to take one of these next year. I'm currently taking the OSCP as I heard it was a good course for content alone! and I thought this would be a good start to my prep. I'm also reading hacking windows and linux titles having finished hacking exposed 6. oh and hacking web apps exposed all latest edition. I shall work through the met unleashed course also and up my scripting of pearl or should I use python? other than that I was going to download the exam outline and research the topics off the net.... would this be enough to pass one of these exams? sorry but 1600 is a lot to lose when its self funding - failure is not an option!!!! I've seen the topics outlined and it does not strike me with fear as many I've studied, but its hard to really know the level required. Any advice from guys who have sat these exams or the prep they did would be great...

totally agree Don! just like risk management try to influence your own destiny as best you can.... Thats why I decided to take my CISSP and CISM back to back and paid for all the fees myself without any support. Now I'm planning to take on the TIGER or CREST pentesting qualification which is the defacto needed to practice in the UK as its levels with the CHECK CESG... oh and that chapter give away on setting up a lab has come right on time :-) I'm just finishing the OSCP and reading reading reading to get ready for my goal of early next year... I'm actually starting to think sod working for others and starting up my own company, but I think it maybe wise to get some experience under my belt first... I might offer some services to local charity first for free. The trouble with were I am is you can't even discuss security out in the open and pentesting is just scripting to them... or your labelled as a techy who can't understand the business... I strive for both thanks! some have a passion for infosec and some just do it as a job I guess... tick the box and move along and don't put your head above the trench! If only my middle\leadership mangers had this viewpoint http://www.accountancyage.com/accountancyage/features/2248171/tighten-security-4788678 right on Jay abbott
