Question

Compromised server

Asked by: pma111

Can I ask your opinions, be it based on exprience or knowledge, on the potential impact of a malicious insider compromising one of our servers. Say for example we have 2 servers, with win2003 server as the OS, one runs an Oracle DB, the other IIS. If someone compromised a windows account with admin priveleges, could you give me a few examples on what this insider could potentially do maliciously against that server - network - data - applications etc? I appreciate the server should be protected by strong passwords on only the neccesarty amount of servers, but Im doing some risk analysis so could do with a steer on the risk were a server to be compromised.

with admin privileges he has full control over the oracle server

execute "sqlplus / as sysdba" on the command shell allows anything on the oracle DB (no need to know the oracle password)

---

The IIS server can also be managed by the administrator, allowing all kind of manipulation from spam provider to trojan distributor, you name it.

with admin privileges gone you don't own the machine any more and the risk analysis could say this: should the malicious insider choose to do so, he could fabricate an intricate ring of nazi child pronographers out of the company board/management and have them all locked up for a long time.

thats how f**ked you'd be. so, please, take security seriously.

btw: the scare tactic works at least a few times (when for example you need a budget to install a tripwire type of change monitoring application on those two servers, etc)
:P

What can attackers do with admin privileges? Anything and everything, game over, case closed, their imagination is the limit. They can access any data that is or will be there, destroy it or alter it. They can use any resources you have available and carry on attacks towards everything the server can connect to.

Thanks for the input

 

by: pma111Posted on 2009-09-10 at 02:07:27ID: 25298476

n/b coccoobill, excuse my ignornace but could you give me some examples of resources available to carry out attacks

 

by: CoccoBillPosted on 2009-09-10 at 03:18:25ID: 25298755

Your network connections, processing power, data storage etc. The attacker can for example use them to send out spam, distribute pirated material, carry out DOS attacks, brute-force passwords, calculate protein folding or whatever they feel like doing.

 

by: TolomirPosted on 2009-09-10 at 05:55:08ID: 25299653

And they can steal all data on the oracle server, maybe someone is buying that stuff.

A competitor maybe...
