Is your firewall configuration correct and up to date?
Updated December 4, 2017
A firewall is the first line of defense around a network, monitoring incoming and outgoing traffic. With traditional firewalls, an administrator has defined the traffic filtering rules. Manual updates are routinely needed to improve the firewall’s monitoring, security and reporting ability. Outdated firewall rules may allow unauthorized access into the network and leave a company open to a cyber attack.
The more complicated a network is, the more complicated is the management of the firewall(s). Next Generation Firewalls reduce the number of manual tasks an administrator needs to perform to keep the firewall(s) updated. But, especially if there are multiple firewalls in a complex network, a checkup is advisable to ensure that no errors have been made and there are no compliance gaps.
An incorrect or out-of-date firewall configuration can:
- Change the performance of business applications
- Leave a network perimeter exposed to cyber security risks
A Perimeter Assessment: a detailed analysis of your firewall setup
A Perimeter Assessment looks for holes in a firewall(s) and analyzes the external firewall traffic flow in and out of a network. A Perimeter Assessment is essentially a detailed firewall “checkup” that prioritizes potential network risks. This management planning document not only identifies external network vulnerabilities, it ranks them from high to low risk, and provides recommended solutions.
Specifically, a Perimeter Assessment provides a detailed risk analysis report of:
- External vulnerabilities
- Expired certificates
- Updates needed
- Configurations that need to be changed in your firewall setup
- Information leaks
- Recommendations for remediation of found issues and concerns.
A Perimeter Assessment will reveal if a firewall is up-to-date or needs an upgrade.
Once permission is given, Nettology can run a series of tests on a company’s IT network perimeter. The results of this firewall “checkup” will show the current state of a company’s external network, revealing where a firewall may need shoring up. The title of the official document — “External Network Vulnerabilities Summary Report Security Assessment” — may seem overwhelming, but Nettology will present the data results in clear terms. The findings in this network vulnerability assessment report will help a company prepare for compliance reviews. Nettology’s skilled engineers can also implement any needed firewall upgrades.
