Product Description

As distributed workforces become more prevalent, securing the network edge is more critical than ever to ensure users can access the data and applications they need when they need them.

In securing your distributed workforce, cloud-delivered security is not enough. You must start by putting employees first, allowing them to securely access the data and applications they need to do their jobs effectively, and helping you streamline yours. Unbroken visibility from client to workload, security assurance, and a single policy framework are essential tools to help secure your remote workforce.

Access should not increase the organization's risk. Additional security is needed to combat the increasing number of threats organizations face while maintaining user access to new applications on different devices. Juniper Networks® SRX Series Firewalls deliver integrated next-generation firewall (NGFW) protection services with application awareness, user identity, and content inspection for all physical, virtual, containerized, and as-a-service deployments. In addition, the SRX Series firewalls offer intrusion prevention, SSL inspection, anti-spam, anti-virus, URL filtering, and unknown threat detection, providing a single security platform that addresses a range of security requirements from a common architecture.

 

Architecture and Key Components

The SRX Series' NGFW services architecture includes several key components that provide a powerful platform to protect enterprises and MSPs from constantly evolving and sophisticated cyberattacks.

 

User Identification and Access Control: User Firewall

User identity is a core requirement of next-generation firewalls that enables administrators to create security policies that reflect business needs rather than network requirements. This flexibility creates a powerful mechanism for defining, managing, and refining security policies by creating firewall rules based on user identity rather than an IP address. Through Juniper's User Firewall feature, an SRX can associate network traffic with a specific user by integrating directory services such as Active Directory. Organizations can define policies to allow application use based on individual users or user groups, enabling more powerful but simpler security controls. Through User Firewall, security policies can be expressed in terms of groups, allowing security policies to continue functioning as users are added or deleted from groups. In addition, the User Firewall provides visibility into application usage at the user level rather than an IP address, giving you powerful insights into application traffic traversing the network. Security administrators can reduce the threat footprint by adjusting security policies to align application usage with security and business practices.

 

Application Identification and Control: AppSecure

The days of tying applications to traditional port-based communications are long gone. Today, new applications are designed to change ports and protocols dynamically. Some are designed to tunnel through services such as HTTP web traffic. This means applications can be used anywhere, at any time the user needs. Empowering users to access applications anywhere poses a challenge in defending against a constantly changing threat landscape that directly targets applications and passes through traditional network-layer protections to protect the enterprise.

Juniper NGFW Services offer a powerful security platform well equipped to meet this challenge. At the core lies AppSecure, which offers robust visibility and control over applications on the network.

AppSecure quickly recognizes applications and surfaces the application name, description of the service, and inherent level of risk, regardless of port, protocol, or encryption method.

Offering deep application visibility and control, AppSecure provides the context that links application use to a user, regardless of location and device. Furthermore, AppSecure understands application behaviors and identifies vulnerabilities, enabling administrators to block risky applications before they can do any damage. AppSecure helps reduce an application's threat footprint by allowing the definition of granular security policies, such as the level of deep packet inspection required and to which users or groups are allowed access.

AppSecure enforces quality of service (QoS) at the application layer, forwarding traffic based on applications and providing multi-path routing capabilities for critical application traffic.

 

Exploit Protection: Intrusion Detection and Prevention (IDP/IPS)

Juniper's intrusion prevention system (IPS) is tightly integrated with Juniper SRX to mitigate network and application exploits and protect against a wide range of attacks. Juniper's intrusion detection system (IDP) constantly monitors for new exploits against recently discovered vulnerabilities, keeping network protection up to date against the latest cyberattacks and stopping them at the exploit stage before they gain a foothold inside the network. IDP signatures can be enabled in detection-only mode or inline to block malicious traffic directly.

Custom signatures can be created using existing signature sets. You can create policies using a pre-defined policy template or based on custom signatures to keep network traffic protected. It allows you to define policy rules to match a section of traffic based on a zone, network, and application and then take active or passive preventive actions on that traffic. You can also take packet capture before and after the attack for further analysis.

Real-Time Protection: SecIntel

SecIntel provides verified threat intelligence to all points of connection across the network to block malicious traffic, enabling a threat-aware network. To help reduce risk, SecIntel can be deployed on the SRX to block malicious traffic originating from malicious IP addresses and domains without needing deep packet inspection. SecIntel's threat feeds are automated and constantly updated. Additionally, these feeds are scrubbed and verified by Juniper Threat Labs to maintain high detection efficacy and reduce false positives. SecIntel can help reduce the load on the network.

 

Block Known Threats: Network Anti-Malware

Malicious files, including ransomware and adware, are becoming more prevalent from multiple attack vectors. These threats compromise network endpoints and make them vulnerable to data theft, including credentials and personally identifiable information (PII). Detecting and blocking malware and unwanted files at line rate before they reach an endpoint is critical to safeguarding users, data, and infrastructure against attacks. Juniper’s AI-Predictive Threat Prevention predicts and prevents known and zero-day malware at line rate by using AI to effectively identify threats in packet snippets and reduces false positives by filtering out non-threatening activities. It helps human experts focus on more critical security tasks and discover the real, dangerous threats at line rate for the entire attack lifecycle—keeping the network safe from initial and all subsequent attacks. Juniper understands that when there is an attack, every second counts.

Juniper combines cloud-based file reputation intelligence and malware signatures that remain active for the entire attack lifecycle with the SRX Series NGFW to deliver lightweight and fast security. Gain a highly effective perimeter defense against known threats without slowing down your users or business. NGFW delivers lightweight and fast security. The result is a highly effective perimeter defense against many known threats, which doesn't slow down your users or business.

 

Browsing Defense: Enhanced Web Filtering (EWF)

Users spend over half their time browsing the Internet and using web-based tools. Web traffic must be both legitimate and safe. At the same time, specific web applications, such as online banking or healthcare, must remain private. EWF allows administrators to block unwanted URL categories, such as gambling and malware sites and enables selective decryption to keep business traffic safe from threats. In contrast, users' personal traffic can remain private. To reduce attacks, EWF contains more than 200 URL categories that can be used within security policies on the SRX.

 

Encrypted Protection: SSL Proxy

SSL has become the universal method for authenticating websites and encrypting traffic between Web clients and Web servers.

Since SSL content is encrypted, users can download malware directly onto client endpoints. Typically, organizations have no visibility into SSL connections, leaving them blind to any threats transmitted over HTTPS to their corporate enterprise clients.

Juniper offers a powerful application-level SSL proxy that sits between client and server, intercepting encrypted traffic, terminating the session, and re-initiating the connection towards the end destination. It can be used as an SSL “forward” proxy that sits between users on the corporate LAN and their access to the Internet, protecting the end client. It also intercepts HTTPS traffic by acting as a gateway at the enterprise perimeter and terminates the encrypted traffic. At that point, unencrypted traffic is immediately inspected to determine compliance with security policy, as set by the security team. Traffic is then handled by proactive malware engines that will instantly block malware, thwarting any security breach.

The SSL Proxy can be configured with exemptions that prevent traffic between certain URLs from being decrypted for user privacy protection. The exemptions can be set based on user groups, URL categories, or custom categories. The SSL proxy provides security between clients and the web server the firewall protects. This can be termed as SSL “reverse” proxy, which sits between external connections and web servers that are managed within the organization.

 

Zero-Day Threats: Juniper Advanced Threat Prevention (ATP)

Juniper Advanced Threat Prevention (ATP) is Juniper's threat intelligence hub and uses machine learning algorithms to provide complete advanced malware detection and prevention. ATP supports threat detection without breaking decryption and surfacing compromised devices. When integrated with SRX Series Firewalls, Juniper ATP leverages a global threat database to deliver threat intelligence, dynamic malware analysis, Encrypted Traffic Insights, and adaptive threat profiling. Juniper ATP is offered as a cloud-based service or as an on-premises appliance.

Juniper’s AI-Predictive Threat Prevention provides anti-malware capabilities at wire speed, ensuring that you don’t have to compromise your throughput performance for better security, all while eliminating patient zero. Signatures generated by AI-Predictive Threat Prevention remain active for the entire attack lifecycle, instead of a mere 24 hours after discovering the malware like other technologies, and the active signatures provide effective protection against subsequent attacks.

Juniper ATP protects against trojans, worms, ransomware, botnets, IoT threats, and DNS threats like Domain Generation Algorithm (DGA) generated domains and DNS tunneling.
