Windows XP image after login

I work at a university and I noticed when I log into a campus computer lab, I can install anything that I want, do whatever I want.. delete system files, whatever…

when I log off and log back in, it is as if I was never there. it is almost like there is an image somewhere and somehow the image gets reapplied at each login, or none of your settings are changed.. ?? I am not sure. anyone know how to do this? I have a 20 station lab myself and sometimes users mess up icons and stuff.. I would like everything to reset as to a specific profile.

They still might be something for you to consider.

If my linux server can be attacked?

My server is install with kernel: 2.6.9-11.19AX #1 Fri Aug 5 05:12:07 EDT 2005 i686

It has run one year with heavy traffic

I haven’t upgrade my server to higher kernel

I wonder If my linux server can be attacked?

I use Apache/2.0.52
I use iptables and open ports: SSH, HTTP, HTTPs

Have any serious problems with my server?
(for example To gain root login)

Your Linux server is a complex assortment of software, all of which can (and do) have vulnerabilities. In the past year, there have been patches to the kernel, various drivers, and various applications. Many of them are security patches. You can view them at http://cve.mitre.org/cve.

Letting your server get behind on patches is a bad strategy. There’s been a lot of work put in to package management (yum, apt, etc.), so there’s very little risk in making regularly updates a part of your standard system management. Just be sure to stick to applications that are available as packages to ensure that the dependency checks are always done.

We’re in the era of zero-day exploits, and you have an exposed server. You need to stay current on more than just your apache server and ssh-based applications.

Do you run DNS, if so you should upgrade BIND quickly, if you use TinyDNS your safe, email services typically have a bad habit of being exploitable, but Apache and SSH are typically pretty strong, however SSH depending on your distribution has had some recent exploit issues. You should have a cron job to kick off yum or aptget to run your updates.

Documents being deleted but leaving folders/subfolders intact.

Seems something has deleted all documents, spreadsheets, pictures etc but left the various folder and subfolders intact. On searching here and generally on the internet we couldn’t seem to find such a report and believe it may be a new threat of some kind. Can anyone provide information on this. Many thanks in advances.

Try running a file recover application there are many to choose from

Running one of the tools will verify if the files have been deleted and can be recovered.
