7 Firewall Capabilities That Enhance Network Security

February 24, 2020

As the threat landscape continues to evolve, organizations must implement security technologies to protect their organization from threats like malware and DDoS attacks. According to the 2018 Cybersecurity Survey Report by the CIRA, 61 per cent of organizations monitor their networks and use firewalls to identify cyber risks to their organization. Firewalls are a traditional security tool that help organizations secure their network edge. As threats got greater and technology improved, firewalls evolved their capabilities to become next generation firewalls (NGFW).

How Next Generation Firewalls Protect Organizations  

A NGFW firewall has the same benefits of a traditional firewall but includes enhanced capabilities that allow real time protection against malware, vulnerabilities and network attacks. 

Many firewall services like our Secure IT Firewall solution feature next generation firewalls to provide organizations with greater protection against the evolving threat landscape. Secure IT Firewall also contains years of Hybrid Intelligence that combines both human and machine learning to apply rules to specific applications and other functions to allow or deny traffic.

7 NGFW Capabilities for Advanced Protection 

1. Advanced threat protection 

Most traditional firewalls integrate with a separate intrusion prevention system (IPS) to gain additional security features. Next generation firewalls have IPS capabilities built in to protect against a wide variety of threats, such as DDoS attacks, malware and spyware. Further integration with threat intelligence systems like SIEM provide advanced layers of protection to defend against the modern threat landscape. 

2. SSL Inspection

Malicious threats can be hidden within encrypted web traffic. In order to filter out malicious content, the NGFW intercepts encrypted web activity to filter out malicious activity through a “man in the middle” approach. The NGFW will first decrypt the incoming web traffic and then scan for threats like malware or viruses. After its examination, the traffic will be encrypted and forwarded to the user so that the user can access the data as originally intended. 

3. Application Control 

The users on your network use several tools on their devices, such as email, social media and other vendor applications. Some of these web applications can be malicious and lead to open backdoors that can be exploited to enter your network. Application control allows organizations to create policies that either allow, deny or restrict access to applications. This not only protects organizations by blocking risky applications but also helps them manage their application traffic to ensure availability for business-critical resources. 

4. User identity awareness

User identity awareness allows organizations to enforce policies that govern access to applications and other online resources to specific groups or individuals. The NGFW integrates with your authentication protocols (such as LDAP or Active Directory) so that access is governed by user identity as opposed to IP address. User identity awareness not only helps organizations control the types of traffic allowed to enter and exit their network but also manage their users.

5. Deep packet inspection

Deep packet inspection inspects data to identify and filter out malware and unwanted traffic. By inspecting the content of a data packet, the NGFW can intelligently determine which applications are being used or the type of data being transmitted. This allows the firewall to block advanced network threats (such as DDoS attacks, trojans, spyware and SQL injections) and evasion techniques used by threat actors. 

6. Centralized Management 

Firewalls need proper security management to ensure that they meet the security needs of the organizations that need protection. Firewall capabilities need to be updated and firewall rules need to ensure they are being properly enforced. Centralized management of your firewall(s) is crucial in gaining on overall view of your firewall configurations. Organizations need to ensure they can scale their firewall to ensure that their organization has maximum protection to fit their growth needs. 

7. Reporting and insights 

Firewalls generate logs that detail information about security and network traffic that security administrators review to understand the overall activity. This information provides organizations with useful insights to help them prioritize application traffic and understand their network security and monitor user activity.
