Firewall App Blocker (fab V1 7 Download)

Good afternoon! It would be convenient to add the "hide system processes" checkbox in the add processes window. It would be convenient for novice users.
It is very useful to see a list of all working rules. Including those built into windows and created earlier. That is, a complete list of firewall rules. You need a search field, the ability to filter (enabled/disabled), color marking, manual sorting (dragging).
For example, you can use Binisoft Windows Firewall Control.
You also need to check the functionality of built-in utilities, such as ping, tracert, and so on. What I wrote about earlier.
Click the Add button under the list of applications and services, then select the apps or services you want to add. After an app or service is added, click its up and down arrows and choose whether to allow or block connections through the firewall.
Specifically, I'm writing a windows service which will expose an http RESTful service for other processes on the machine. The service will be running on a non-standard port in the dynamic/private range - ie not port 80 or similar. Do I need to worry about any firewall that might be running on the machine?
Firewalls usually block network calls based on protocol(tcp, udp, http, etc), port, and/or ip. So if you have a local process making a tcp/ip call to your loopback address (127.0.0.1) then yes the firewall could be affecting the local process.
To be more specific to your question, most firewall programs should be configured to only allow specific address and ports and block everything else. So I would think you should consider this in your design.
I installed yesterday an application for my Linux Mint os called Portmaster. It is an open source firewall for PC. There is also Windows version available. I use free version which seems to be sufficient for my use case.
However, one of my clients is behind a relatively simple BT Home Hub which doesn't offer much in terms of outbound firewall connectivity - and they have a pretty unmanaged Windows 2012 server sat on their LAN. I was surprised (well not that surprised) to learn that the default on Windows 2012 firewall outbound is to allow all outbound traffic. I'd always assumed that because there are a whole block of enabled outbound rules sat there that only the ports/programs configured in those rules have access. I was perplexed how I was able to telnet to their ISP's SMTP server without an obvious rule allowing it. Change the default behaviour to block briefly and yes, lost telnet to port 25.
can someone explain how I can refuse an outgoing connection on opensuse firewall by default outbound policy is permissive, and the p2p I explicitly deny an outgoing, according to protocol, remote port and local port.
I can SSH to both of the servers. How can I allow the tomcat server behind the firewall to be able to send data to the MySQL with port forwarding/ssh tunnel? I've read about the conecepts but I just can't seem to grasp my head around it, hence me asking for practical help and explanation.
I have recently installed a pan device in TAP mode, with a port mirroring on a cisco switch that copy traffic to the tap interface. On the policy cofigured to allow all between TAP zone and TAP zone, i have configured default security profiles, specially url filtering profile that block some categories by default, so the question is, while beeing in tap mode, is it possible that the firewall actively participate in the traffic, by blocking some urls for example? I wanr also to know if the block action in url fiktering profiles is achived by a quiet drop of paquets or by a sending of TCP RST paquet?
The script works by spoofing a packet from the target server asking for openinga related connection to a target port which will be fulfilled by the firewallthrough the adequate protocol helper port. The attacking machine should be onthe same network segment as the firewall for this to work. The script supportsftp helper on both IPv4 and IPv6. Real path filter is used to prevent suchattacks.
It appears to me that the Eset firewall can't process the "(" and ")" symbols in the file name; i.e. LenovoVantage-(VantageCoreAddin).exe. I have never seen a file name using those symbols although they are allowable characters.
Those are not actually identical. Firewall rules are created for a specific file, however, the firewall internally works with aliases / hard links which are different in this case. According to the output of fstuil shown above, there can be 8 rules for 1 file that appear identical but they are not identical in fact because each is created for a different alias of the file.
We now know what is causing it. It's that we started to ask the Anti-Stealth about processes both from the kernel and user mode when they start compared to asking when they were already started in older firewall module versions. We'll make some optimizations to reduce the number of rules due to processes differently identified at various stages of running by the operating system that provides data to Anti-stealth.
I need to try & block GoToMyPC connections to company machines at the firewall. Users here have local admin rights, it is a requirement of the SW we use & there is no way around it. A few people have started using GoToMyPC instead of the VPN we pay for & have set up for them since it is 'easier' than the VPN & RDP we recommend.
Rivitir what OpenDNS would you recommend for a small company, I wont get approval for the Enterprise option since we already pay for content filtering etc on the firewall. Are any of the free options suitable / allowed for companies?
If the IP is static you can block using a firewall port 443 to/from the IPs you want to block. Otherwise, you are looking for an IPS like Snort You can use it to configure a specific rule for blocking a signature or pattern of SSH traffic with whatever other parameters you might need.
Besides this, NBNS rules had to be disabled manually, in order to prevent NB-Name-Out network traffic. By stopping this traffic we would make sure that an attacker cannot abuse NBNS spoofing attacks, since the built-in firewall would stop all such outgoing requests. You can see the rules, with their respective profiles in the following picture:
So, I got in touch with Microsoft and the MSRC guys verified that this is indeed an issue with the firewall. The conversations with the MSRC guys were great and, as you can see, the patch has been released that fixes this vulnerability.
If you are setting up a firewall from a remote machine, it is vital that you know what the effect of every rule that you add is. Incomplete rulesets may lock you out completely - which is a very unpleasant experience.
Make sure you understand the concept of iptables and iptables rules. Make sure you understand what the rules mean before you are adding them. The iptables manpage and netfilter.org are great help with this.
Notice also that when the host from behind "inside" initiates the connection on these destination ports then the reply/return traffic of the remote host is automatically allowed through the firewall as were talking about a statefull device that keeps track of the connections and their states formed through the said device.
