Overview:

Data centers increasingly rely on server virtualization to deliver services faster and more efficiently than ever before. The virtualized data center, however, introduces new challenges that require additional security considerations beyond those needed to secure physical assets.

Virtual machines (VM) can be highly dynamic and elastic in a virtualized data center, with frequent additions, moves, and changes. These frequent changes complicate the ability to attach security policies to a VM instantiation and track security policies with VM movement to ensure continued regulatory compliance. In short, the dynamic and flexible nature of virtualization can easily lead to a loss of visibility and control.

Network and security professionals must perform a delicate balancing act, delivering the benefits of virtualization and cloud technologies without undermining the organization's security. This challenge can only be met by a security solution that can keep pace with evolving threats while matching the agility and scalability of virtualized and cloud environments-without sacrificing reliability, visibility, and control.

Juniper addresses these challenges head-on by extending the capabilities of the award winning Juniper Networks® SRX Series Services Gateways to the virtual world with the vSRX Virtual Firewall. Juniper makes security easy by securing the cloud at every level: between applications, between instances, and across environments.

Powered by Juniper Networks Junos® operating system, the vSRX delivers a complete and integrated virtual security solution, including L4-L7 advanced security services, robust networking, and automated life cycle management capabilities for service providers and enterprises alike.

The vSRX's automated provisioning capabilities allow network and security administrators to quickly and efficiently provision and scale firewall protection to meet the dynamic needs of virtualized and cloud environments. By combining the vSRX with the power of Junos Space® Security Director, administrators can significantly improve policy configuration, management, and visibility into both physical and virtual assets from a standard, centralized platform.

For service providers and organizations deploying service-oriented applications in software, the vSRX's portfolio of virtualized network and security services supports a variety of Network Functions Virtualization (NFV) use cases. The vSRX also supports Juniper Networks Contrail, OpenContrail, and other third-party solutions, and can be integrated with other next-generation cloud orchestration tools such as OpenStack, either directly or through rich APIs.

Intrusion Prevention System (IPS)

IPS for vSRX controls access to IT networks to protect systems from attack by inspecting data and taking actions such as blocking attacks as they are developing-and before they succeed-or creating a series of rules in the firewall. IPS tightly integrates Juniper's applications security features with the network infrastructure to further mitigate threats and protect against a wide range of attacks and vulnerabilities.

Features Feature Description Benefits
Stateful signature inspection Signatures are applied only to relevant portions of the network traffic determined by the appropriate protocol context. Minimizes false positives and offers flexible signature development.
Protocol decodes More than 65 protocol decodes are supported, along with more than 500 contexts to ensure proper protocol usage. Improves signature accuracy through the precise context of protocols.
Signatures There are more than 15,000 signatures for identifying anomalies, attacks, spyware, and applications. Attacks are accurately identified and attempts to exploit known vulnerabilities are detected.
Traffic normalization Reassembly, normalization, and protocol decoding provided. System overcomes attempts to bypass other IPS detections by using obfuscation methods.
Zero-day protection Protocol anomaly detection and same day coverage for newly found vulnerabilities provided. Protects networks against any new exploits.
Recommended policy The Juniper Security Team identifies attack signatures as critical for the typical enterprise. Installation and maintenance are simplified while ensuring the highest network security.
Active/active traffic monitoring IPS monitoring includes active/active vSRX chassis clusters. Support included for active/active IPS monitoring.
Packet capture IPS policy supports packet capture logging per rule. Users can conduct further analysis of surrounding traffic and determine additional steps to protect the target.

Application Visibility and Control with AppSecure

AppSecure is a next-generation application security suite for vSRX and SRX Series Services Gateways that delivers threat visibility, protection, enforcement, and control.

Whether needing to understand how many users are accessing cloud-based applications like Facebook every day, or needing to know what applications are using the most bandwidth, AppSecure delivers powerful visibility and ongoing application tracking. With open signatures, unique application sets can be monitored, measured, and controlled to tie closely to the organization's business priorities.

Features Feature Description Benefits
AppTrack Analyzes application data and classifies it based on risk level, zones, source, and destination addresses. Tracks application usage to identify high-risk applications and analyze traffic patterns, improving network management and control.
AppFW Creates application control policies to allow or deny traffic based on dynamic application or group names. Enhances security policy creation and enforcement based on applications rather than traditional port and protocol analysis.
AppQoS Meters and marks traffic based on the application security policies set by the administrator. Prioritizes traffic and limits and shapes bandwidth based on application information and context to improve overall performance.

Juniper Advanced Threat Prevention

Juniper Advanced Threat Prevention integrates with the vSRX to provide dynamic, automated protection against known malware and advanced zero-day threats, resulting in instantaneous responses

Security policies determine if a session can originate in one zone and be forwarded to another zone. The vSRX receives packets and keeps track of every session, every application, and every user. As a VM moves within a virtualized or cloud environment, it will still send packets to the vSRX for processing, continuously communicating in a secure mode.

E-mail analysis and remediation Isolates and quarantines malicious malware, preventing e-mail from being used as an attack vector. Machine learning algorithms analyze e-mail traffic, detect malicious attachments, and block files at the firewall.
Threat intelligence Uses powerful open APIs for seamless integration with third-party vendors, providing multiple threat intelligence feeds and reducing the attack surface.
Encrypted Traffic Insights Restores visibility into traffic lost due to encryption without the heavy burden of full TLS/SSL decryption.
Adaptive Threat Profiling Enables a quicker response time to combat the continuous onslaught of new threats. Organizations can use ATP Cloud’s Adaptive Threat Profiling to automatically create security intelligence threat feeds based on who and what is currently attacking the network.

High Availability (HA)

The vSRX provides mission-critical reliability, supporting chassis clustering for active/active and active/passive modes. The HA functionality provides full stateful failover for any connections processed and for cluster members to span hypervisors. When configured in a cluster, vSRX VMs synchronize the connection/ session state and flow information with IPsec security associations, Network Address Translation (NAT) traffic, address book information, configuration changes, and more. As a result, not only is the session preserved during failover, but security is also kept intact. In an unstable network, vSRX also mitigates link flapping.

Juniper Secure Connect

Juniper Secure Connect is a highly flexible SSL VPN application that provides secure access to corporate and cloud resources for employees working away from protected resources. Juniper Secure Connect is available for desktop and mobile devices including Windows, Mac OS, Android, and iOS.

Performance

Traditionally, customers must choose between scalability and performance. The vSRX solution is optimized to leverage multiple virtual CPUs to maximize packet processing and overall throughput in the virtual environment. Each vSRX VM also has multiple virtual network interface cards (vNICs), which can be connected to various virtual networks to simultaneously protect multiple network segments. The vSRX operates from within the virtual fabric, providing the best of both worlds-strong security with the performance needed to support a virtualized or cloud-based environment.

Leveraging the Software Receive Side Scaling implementation, the vSRX provides additional cores* beyond the minimum two vCPU, up to a maximum of 32 vCPUs, to the same instance without having to certify a new instance image. By using 17 vCPUs from a single socket, the vSRX can achieve up to 98 Gbps performance.
