| Leaktesting |
The best test to see if your pc is safe from cyber attacks is to run a Leaktest.
A Leaktest checks to see if your firewall is protecting vulnerable areas from cyber attacks.
It tries to attack your pc using the same methods as malware, simulating rootkits, invasions, hijacking, impersonation etc, and if your firewall is any good it
blocks every attempt. If your firewall fails an attack test then it's time to tighten up your firewall settings. If it still fails then it's time to get a new firewall.
Check the settings/configuration of your firewall to see if you can, at least, stealth your ports; increase types of detection; enable protection on buffer overflow,
ARP cache, registry, memory; block applications that aren't digitally signed; monitor processes, hooks, drivers, DNS/RPC client, keyboard, etc.
For indepth research into your firewall's vulnerabilities visit MatouSec where they list the types of cyber attack you should test your defenses against.
If only have Windows Firewall protecting you be aware it is not enough by itself, it fails all leaktests in several key areas.
Download Comodo LeakTest
Use this to test a new installation of Comodo Personal Firewall. However, you can use it to test a pc running a different firewall. If it fails
When you run CLT your firewall should pop up a warning. it means your firewall is capable of detecting that type of cyber attack. Click Block or Deny and
the leaktest will display 'Protected' for each test. Note- if you have a realtime antivirus monitor then it should give you a virus warning when it encounters the
leaktest file CLT.exe , you can safely allow it to run initially, just block each of the tests to get an accurate result.
Download Comodo Parent Injection Leak Test Suite
The CPIL suite contains three separate tests especially developed by Comodo engineers to test a firewall's protection against parent injection leak attacks.
Each of the three tests involves the user typing some random text into a text box which CPIL will attempt to transmit to the Comodo servers.
Download Microsoft Baseline Security Analyzer (MSBSA)
Choose MBSASetup-x86-EN.msi for normal 32-bit XP,Vista,7
Choose MBSASetup-x64-EN.msi for 64-bit XP,Vista,7
MSBSA scans your pc for security vulnerabilities. It checks your settings for Windows Updates, Windows Firewall, password strength, guest account,
excessive Administrators, remote access, unnecessary services, file sharing, IIS and SQL issues. To work, it requires the following services to be started: Workstation, Server and Net Logon. To switch these services on run MSBSAOn.bat, when you have finished leaktesting run MSBSAOff.bat unless you
use these services, normally they are not required for a home pc. Your also need to be connected to the internet to test your Windows updates status.
To begin a scan with MSBSA click Scan A Computer, under Computer name: enter your Workgroup name and the computer's name. You can find these
by rightclicking My Computer (from the desktop or Start menu), select Properties then click the Computer Name tab. Type the names into MSBSA in this
format: workgroup/computername (e.g. mshome/nicholas). When the scanning has finished go through the results and follow the advice under
'How To Correct This' for each vulnerability detected. This may be as simple as creating a password, switching on Automatic Updates or deleting
an unused user account, however certain issues like SQL Server vulnerabilities may need indepth analysis to solve.
