Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Cyber Threats to Small Businesses (Part 2)
Cyber Threats to Small Businesses (Part 2)

The evolving cybersecurity landscape presents SMBs with a host of new threats to their clients, their data, and their bottom line. In part 2 of this blog series, learn three quick processes Webroot’s CISO, Gary Hayslip, recommends to help small businesses beat modern threats.

Are there any well-known repercussions related to disabling NetBIOS for my workstations. There is a lot of broadcast chatter I’d like to eliminate. Also, many of the workstation firewalls are blocking UDP 138 and 137. This blocking combined with the broadcasts results in security logs that are being written to four times a minute per workstation. Quite a lot of work for nothing possibly?

I disabled netBIOS on one workstation and I’m not seeing any issues yet. Is it OK to disable it networkwide?

PFSense v. 2.2.4, connected to a Comcast circuit with 30 down, 15 up.  A computer connected directly to the PFSense tests speeds at right about 30 / 15.  But if a switch is introduced, the speed drops to 2-4 / 10-12.  Several switches have been tried - all 10/100/1000, none managed or manageable.  Several computers have been tried.  Same result with each.  In each case only the testing computer and the PFSense were plugged into the switch - no other devices.  In the PFSense, the LAN interface is set to automatic and shows a connection at 1000 BT, full duplex.  What could possibly be happening that slows the internet down so significantly simply by virtue of introducing a switch?  And it should be noted that upload speeds are still good, it's just download that drops down significantly.   I do realize that the PFSense needs to be updated to a more recent version, and I will do that, but since the speed is just fine when the computer is directly connected I really don't think the version upgrade is the issue.  Any ideas are appreciated!

Many windows 7 workstations on the LAN have full security event logs. The issue is from many netBIOS broadcasts that are being blocked by the Windows firewall and then logged as an Audit Failure.

Why are all workstations broadcasting to each other so much that the logs are filling?
Is the broadcasting normal behavior?
Will it break the network if I disable or block netBIOS from all workstations? I do use the c$ share remotely.
Possibly the firewall shouldn't be blocking this?

Tons of questions because I want to understand this behavior. Thanks!

We have a cloud based firewall provided by our MPLS provider. They recently moved from Cisco to Fortinet. We are given access through a web dashboard.

I knew how to to this with the cisco but not the fortinet. I'm trying to create a rule/policy where i can group a few internal IP's together where they go out and use the same external static IP.

Does anyone know how I can stop LFD from sending Failure emails for trusted processes? Do I need to 'whitelist' certain processes in CSF?

We have uninstalled a series of apps and 2 apps, Comodo and Sql2016 didn't uninstall completely.  We use iObit Uninstaller and clicked all apps that we wanted to uninstalled, including  the 2 that wasn't successful done.  

Sql2016 is no longer in the Add/Remove programs but services are still active (How do we remove or uninstall these SQL 2016 services?).

Also, when we try uninstall individually Comodo, we can't, we get this message:

failed uninstall
How do we remove or uninstall partial Comodo?)

Cyber Threats to Small Businesses (Part 1)
Cyber Threats to Small Businesses (Part 1)

This past May, Webroot surveyed more than 600 IT decision-makers at medium-sized companies to see how these small businesses perceived new threats facing their organizations.  Read what Webroot CISO, Gary Hayslip, has to say about the survey in part 1 of this 2-part blog series.

Hi,
Having trouble with workstations running a new software program that uses a SQL DB on an SBS 2011 server (Medtech32 Medical Software.)
Disabling the Server's Firewall allows it to run on the workstations.  I've added the Firewall rules to the Server as stated by Medtech but it still doesn't connect.  Any ideas?
The ports as per their docs are:
TCP Port 3050  on internal LAN/WAN
UDP Port 300 on internal LAN/WAN

Thanks.

Hello, I started to configure a PFSense, version 2.4.1. I want to know if it is possible to configure an IPsec multi-WAN failover

Has anyone had any experience configuring this? I already configured the DUAL WAN Failover on the PFSense

I would like that the VPN tunnel can be able to stay up if the WAN fails over.

Thanks in advance

Dear experts, we are testing pfSense firewall but could not access it via LAN network on a PC. This is our diagram:
ISP ------------- pfSense ---------------- Core switch 3750 ---------- PC

with this diagram, we could ping and access pfSense via web browser :
ISP -------------- pfSense -------------- PC

So I guess something wrong with the core switch and vlan setup, but we could not find why. In switch 3750, the interface connected to pfSense has access mode, vlan 100 - the same with pfSense LAN interface.

Could you please suggest?

[Webinar] Cloud Killed the Firewall
When cloud platforms entered the scene, users and companies jumped on board to take advantage of the many benefits, like the ability to work and connect with company information from various locations. What many didn't foresee was the increased risk the cloud can bring to company infrastructure. The more cloud applications we add, the greater the number of vulnerable entrypoints. Most basic firewalls can't keep up.

In this webinar, Skyport Systems explains how legacy DMZ architectures cannot accommodate this highly agile, cloud-connected enterprise, and how companies can create new security policies to adapt to this shift. View the video to learn how to make your enterprise "cloud ready."

I'm having difficulty finding any decent documentation on the Windows Advanced Firewall predefined rules, and the sets of rules that are created when you select a predefined rule to enable.  Can anyone recommend a decent article, blog, or post that explains what each of these rules do?

Thanks!

In a firewall like Palo Alto Networks you can see what traffic has been allowed or denied by source ip, destination ip, protocol, actions etc. How can I see what's being dropped on a particular VPC?

Goal: Allow a user to connect to his desktop computer with RDP  ONLY after connecting vpn.

Environment:   OPNsense/Pfsense firewall
53,25,80,443 allow through firewall-
Currently can successfully rdp  with or without VPN with port forwarding - suspect traffic is hitting the fw on public int/public static  and not the desired private Ip a range allocated VPN connection.

User successfully connects to vpn, receives ip, but cant access local resources.
The client side vpn registers an IP address, the FW sees the connection- Just doesn't seem to allow traffic from vpn to local network

The IP range assigned to vpn  connections 10.  the local ip range is 192.

https://wiki.opnsense.org/manual/how-tos/sslvpn_client.html
and I have successfully  connected to and passed Auth.
*yes i did add rule to allow vpn traffic access to local resources

When connected to VPN , I can not ping my vpn gateway (10.0.0.1), I can not ping any local resources (192.168.37.X)
Outside of the the VPN I am able to make a connection.

Any help would be appreciated
