What is a Firewall?
A Firewall is a network security device that helps organizations and people to keen-monitor and filter incoming and outgoing network traffic. At its most basic, a firewall act as a critical barrier between a private internal network and the public Internet.
A firewall is the first line of system defence that prevents an external attack. Reviewing firewall security will check the firewall configuration, firmware updates, and security configuration. It is mandatory that all firms which communicate through a network should undergo a firewall security review. Most standards like PCI DSS, ISO 27001, SOX and HIPAA require firewall security review.
The main highlight of Deverra’s Firewall Security review is that we help locate weaknesses in network security and determine what existing policies should get updated.
Benefits Of Firewall Security Reviews
- Obstruct attacks on your private network caused by other networks
- Portray a funnel mechanism that set-aside the non-authorized users
- Improve the efficiency of firewall policies
- Determine that there are no vulnerabilities
- Discover issues that the traditional approach cannot identify
- Meet compliance requirements such as PCI DSS, HIPAA, NIST CSF etc
Firewall Security Review Methodology
Our team conducts this process manually by using specific tools. The step-by-step process which we conduct are as follows: –Gathering Firewall Security Review Information
- Network diagram– number of firewalls
- Best standards to be used (PCI DSS, NIST…)
- Critical Asset
Evaluation Of Rules
- Our team conducts a detailed study of the existing rules the client practices, details about scope, and tests its limitation.
Execution
- Security configuration review: Evaluate current security configurations like Authorization, Logging/Alerting, Firmware Patching, and Administrative Access.
- Review of Firewall rule: It says which all services and IP which the firewall has allowed.
Reporting
- Review of Firewall rule: It says which all services and IP which the firewall has allowed.
Review Of Remediation & Final Report
- After the change is made based on the report, we check whether the faults in policies and other practices are up to the level.
- A final report is made based upon the last reviewed details, consisting of a high-level overview, known as an executive-level report and a technical finding report that illustrates all technical aspects.
