So I have to ask the question, why are all the "admins" running as full admin? A backup operator does necessarily not need restore privileges and certainly does not need add users to the domain. Windows is VERY granular. Assign rights to groups. Use the AGULP model In the AGULP model, rights and permissions should only be granted to the local group. Not to users. AGULP Create unique user accounts. Organize (domain) Users into Global Groups. Place Global groups in to Universal Groups Add the Universal and / or Global Groups to the Local Groups Assign permissions to the Local Groups Assign based on Roles. Minimise what you give as rights - do not use the default admin user.

This, to me, however appears to be an issue with the email system's security controls, or an abuse of admin privs on the email server. That would be a much easier location to copy items "sent" and "received" by the HR dpt.

Password function in the normal MS Word application does not help. If you have problem installing the program. You might want to consider saving the file in an alternative storage media such as a USB Thumb drive. -----Original Message----- From: listbounce () securityfocus com [mailto:listbounce () securityfocus com] On Behalf Of WALI Sent: Monday, November 26, 2007 2:24 AM To: security-basics Subject: Securing workstations from IT guys It's a catch 22 situation and I need to make our Windows Xp workstations appropriately secure. Secure from rogue Helpdesk personnel as well as network admins. The HR guys are complaining that their 'offer' letters to prospective employees and some of the CVs that they recieve are finding their way into unwanted hands. I suspect both HR application vulnerability, for which I am undertaking some vulnerability analysis but I also need to protect the PCs that belong to Dept. of HR employees from rogue IT guys. Here are the basics of what I intend to do: 1. Advise all HR users to shutdown their PC before they leave for the day. 2. Change all Local Admin passwords so that even IT helpdesk/other doesn't know them. 3. Advise HR guys to assign passwords to their excel/word files. 3. Do not create shares off c drive giving 'everyone' access. But...because they are all connected to Windows 2003 domain, I still risk someone from domain admin group to be able to start C$/D$ share and browse into their c: drive, what should I do? Also, it's easy to crack open xls/doc passwords, what else can be done? Alternatively, Is there an auditing on PC that can be enabled to track/log incoming connections to C$ and pop up and alert whenever someone tries it out from a remote machine. Pls advise!!
