A firewall is partly responsible for keeping your network safe from untrusted connections. By understanding what your firewall is protecting you against, you can help to identify vulnerabilities before they become bigger security issues.
In reviewing a report from a single month, we analysed the IP addresses that raised red flags using a process called GEO-IP blocking. It allows us to detect where these suspicious IP addresses are located and the results are eye opening. The top initiating locations were from Western Europe and the United States. This indicates that the country maybe a threat but that threat actors may also be using their resources for hosting.
Not only are we able to be kept safer by using firewalls, we use this data to help ensure our data and connections are kept secure. Regularly reviewing these reports helps us to keep up with cyber risks by detecting patterns, reviewing policies in place and strengthening the firewall to prevent breaches.
Do you feed your firewall logs into a reporting system?
