Syspeace for intrusion prevention for the entire server instead of specific applications or services such as FileZilla Server

If you’re managing a server and host various applications and services all of them are reachable for your users and and customers but most likely, and quite often, they’re also reachable for others to try to log in.

To be cost effective, you could be using using a Terminal Server (or Remote desktop Server) and you’ve also got for instance a FileZilla FTP Server to ease file transfers (or the Microsoft IIS FTP server, my hunch is that these two are the most common ones if you’re running a Windows Server environment) and there’s a web interface for the remote applications and so on . There might also be other services on the same server/servers.

Built in intrusion prevention in applications or Windows Server

Some software actually have brute force prevention built into them, such as the FileZilla FTP Server (although, keep in mind that is it not enabled by default) and there could be other software installed that have intrusion prevention built into them. Not within Windows Server though and there are quite a few articles on this blog explaining how it works such as this one about securing your Exchange OWA

An atacker will first portscan your server, search for open ports and try to figure out what services and applications you’re running on them. Even if you’ve changed the default ports, quite often the application will actually reveal itself in the header what it is and what version it is.

You can for instance simply do a telnet session to the port in question and see what your applications actually reveal about themselves.
Simply start a telnet client and connect to the port you’re interested in such as port 25 for SMTP (email) or port 21 for FTP and you’d probably get at least some information on what is running on the server. To gather more detailed and complex information, you probably be using software like nmap.

After that, tbey’ll simply use automated scripts to try and login. If there is a block in some way on for instance FileZilla FTP Server they’ll simply move on to the next port/service , like the RDWeb interface for Remote Desktop and RemoteAPP services and continue the attack since they’d only been blocked on the FTP level so far (usually port 21) Here’s a >previous article describing parts of the anatomy in a hacking attack written by Juha Jurvanen.

If you’re hosting a multiple software and srevices on a server and each of them have brute force prevention builtin , they’ll only block the attack within their own part of the system.
FileZilla will block the brute force on FTP but nothing else.

Using Syspeace as your HIPS , Host intrusion Prevention System for Windows Servers

A key difference using Syspeace as a HIPS (Host Intrusion Prevention System) is that it will block the attacker entirely on all ports if they trigger any of the detectors, rendering the attacker unable to communicate at all with your server on any port (even ping), thus automatically protecting any other service you have running on it.

To illustrate this with something in the “real” world.
If you’ve got a house with multiple doors, the attacker would first try their keycard/key in one of the doors to try to gain access into the house until an alarm is triggered and they would have to move on, but only for that specific door.
After that they’d keep using the keycard/key on the next door and so on.
With Syspeace, they’d only be able to use the keycard on the first door until the alarm is triggered and after that they would be automatically blocked from even trying to use the keycard on any of the other doors since the doors would have “magically” disappeared for them and would be out of reach for them. It would be as if the actual building itself would have disappeared for them.

Download a fully functional, free Syspeace trial for intrusion prevention or even if you’re under attack of a brute force or dictionary attack

Have a look at the Syspeace website and try the fully functional trial for it and see how it can help you to easily and quickly brute force protect your server. We’ve had users downnloading Syspeace and implementing it in minutes during a dictionary attack to have Syspeace automatically deal with it and to block, trace and report the attack. Since the trial is fully functional and free and it only takes a few minutes to set it up, it can be an easy solution to handle an ongoing attack.

Syspeace supports Windows Server 2003 and on (including the Windows Server Small Business versions), SQL Server, Remote Desktop, Exchange Server, Sharepoint, Exchange OWA, RDWeb , Citrix and more. Out of the box. It actually also support Windows 7 and Windows 8 but please refer to his article on when Syspeace is actually useful for you and when it’s not.

Syspeace has blocked more than 3 126 500 brute force and dictionary attackas targetaed agains Windows Servers worldwide.

The Syspeace team has also developed a FileZilla FTP Detector that is in beta and also an Microsoft IIS FTP detector.
We’ve also released a detector for selfhosted WordPress and we’ve released the Syspeace API for .PHP and .NET to enable our users to develop their own intrusion prevention for applications instead of being forced to develop protection into applications themselves from scratch.
The Syspeace API can also be used to protect spcific websites if you’re hostng multiple websites.

#infosec Do bruteforce attacks really exist ?

The other day I sat down and just looked at various statistics on how the visitors ended up here in terms of referrers and keyword searches and one of the terms was “do bruteforce attacks really exist ?”.

This made me smile.

Syspeace has so far blocked over 2.77 Million bruteforce attacks against #windowsserver #msexhange #Sharepoint #remotedesktop #Citrix and #SQLServer worldwide so I dare say they really do exist and they’re very common.

We’ve also published a 30 day list of the most commonly attacked and attacking countries as reported by Syspeace installations around the world. It might be interesting read for you and it can be found here, Syspeace worldwide security staus center.

One of the features of Syspeace is for instance the Syspeace Global Blacklist that is distributed automatically to all Syspeace installations.
If an attacker has been deemed to have attacked X number of different Syspeace customers and Y number of times, it will be automatically put in the GBL and distributed to all other Syspeace installations, making them preemtively blocking the attacking IP address from ANY communicating with their servers that have Syspeace installed.

Any #Cloud service provider or any #outsourcing or #service provider or also any IT techs at a company knows there are hundreds and thousands of intrusion attacks every month but historically these attacks, also called dictionar attacks , have been very hard to deal with so in essence, they’ve given up. Some providers or companies actually don’t even bother turning on logging on the servers, simply turning a blind eye to the actual problem. From an operational point of view, security point of view and from the customers point of view this is of course not acceptable.

There are some previous posts on why it’s been so difficult on this blog for instance this one, Why firewalls, vpns, account lockout policies  and other bruteforce prevention methods aren’t enough.

After we launched Syspeace , service providers, Cloud providers and companies have been given a new, cost efficient, easy to set up and easy to use countermeasure against hacking attempts.

No need to change your infrastructure, hire costly consultants and launch a big, costly project.
Simply download Syspeace trial , install it in a minute and your #remotedesktop #msexhange #Sharepoint #windowsserver is protected.
It couldn’t be easier and frankly, it should be the part of any #Windowsserver Baseline security just as you’ve got antivirus, backups, patch management in place.

Enable logging on your Windows server as described in the Syspeace manual and see for yourself if you’re targeted. You might be surprised.
