Heard of Windows Firewall but not sure what is does? Here’s our guide so you know how better to protect your PC and your network.
Windows Firewall may be a familiar term, but if you were asked to explain what it does, could you? It can offer important protection for your IT security, so it’s worth making sure you know about Windows Firewall, so you can use its protection against cybercrime.
A firewall is a software or hardware-based security system designed to protect a computer or network from unauthorized access, malicious software, and other online threats.
Windows Firewall has been developed by Microsoft to prevent unauthorised access and block viruses from entering to your PC and network. It does this by monitoring and regulating data being transmitted to and from your Windows system, between devices and within your local area network.
Firewalls also create rules that either allow or prevent communications from entering your device from the network and determine which network traffic a device can send to the network. They are a proactive form of defence that track attempts to access the network and prevent them, rather than just flag issues once they access the systems that they are protecting.
The good news is Firewalls can protect your PC and network from a range of attacks, which include:
Firewalls have a critically important role and deliver many advantages on installation:
Windows Firewall is highly effective at what it’s designed to do – prevent unauthorised access to your device and network.
However, while firewalls are a proactive form of defence, designed for a specific task, they don’t remove malware from a system. Neither can they fix your machine if it becomes infected by malware. On the other hand, by blocking malicious traffic or preventing an application from communicating further with a network, it can help prevent further damage to your systems.
If you are experiencing specific issues with your PC, such as slow performance or hardware failure, a firewall wouldn’t be the appropriate tool to use to address these issues.
This does highlight the need not to assume that a firewall is a one-stop approach for cyber security. It needs to be multi-layered and you need the expertise and tools on hand to repair any damage, restart operations and retrieve data.
And systems are under constant cyber-attacks which are evolving and becoming more elaborate and numerous. Hackers are also becoming more sophisticated, so cyber security also needs to become more robust, which requires specialist IT support.
If you have Microsoft Firewall and want to be sure it’s effectively configured and continues to protect your business, with network traffic flowing as it should and a sensible level of security is being maintained, then our IT services team at Syn-Star can support you.
