Security Services
Integrated Strong Security for Data Center,
Campus, Branch and Cloud Deployments
As threats to the network grow more prevalent
and destructive, securing the infrastructure is
critical to maintaining a viable business. Attacks
come from multiple sources in a variety of forms.
Enterprises and service providers need more than
just a security device; they require an integrated
and comprehensive, layered approach to securing
the network, backed by an industry leader.
Taking a Layered Approach to Securing the Network:
With the number of security attacks on the rise, securing the network has become a
critical and challenging task for IT professionals. At Juniper Networks our approach to
securing the network is via a comprehensive layered approach comprised of several
distinct technologies, including firewalls, virtual security for data centers and clouds,
virtual private networks, anti-virus scanning, Web content filtering and anti-spam,
intrusion detection/prevention systems and application security. By employing a layered
security approach, customers benefit from a system of barriers that is many times tougher
than each of the individual components.
Protecting Physical and Virtual Workloads:
The Juniper Networks SRX Series Services Gateways is a purpose-built platform to
perform essential networking security functions. Optimized for maximum performance
and feature integration, the SRX Series is designed on top of the robust networking and
security real-time operating system, the Juniper Networks® Junos® operating system.
unlike general-purpose operating systems, the Junos operating system is not plagued by
inefficiencies and vulnerabilities as it has been designed from the ground up to provide
superior networking and security capabilities.
The SRX Series provides integrated security and LAN/WAN routing across high-density
LAN/WAN interfaces, Juniper Networks integrated security services gateways address
the needs of small to medium sized locations, large distributed enterprises, and service
providers as well as large and co-located datacenters. These services gateways protect
the network from all type of attacks and malware while simultaneously facilitating secure
business-to-business communications.
With cloud computing and virtualization adoption on the rise, the evolution of the data
center brings a new set of challenges to IT professionals. While the need for physical
network security will continue to exist in data centers, organizations will continue to
adopt cloud computing in phases, resulting in a mix of physical and virtualized data center
workloads. This data center model will result in some workloads like those on physical
servers being secured by physical firewalls, while others such as those running on virtual
machines (VMs) will likely face security concerns because traditional security methods
provide zero visibility into VM traffic. To address this concern, Juniper Networks has
integrated its latest security offering, the Juniper Networks vGW Virtual Gateway with the
Junos OS-based SRX Series platform to extend the protections of the SRX Series products
into virtualized environments.
Product Line Highlights:
• AppSecure is a suite of next-generation security capabilities that utilize advanced
application identification and classification to deliver greater visibility, enforcement,
control, and protection over the network.

Perimeter Defense Begins with Network-Level
To protect against network-level attacks, Juniper Networks devices use a dynamic packet
filtering method known as stateful inspection to unmask malicious traffic. With this
method, firewalls collect information on various components in a packet header, including
source and destination IP addresses, source and destination port numbers, and packet
sequence numbers. When a responding packet arrives, the firewall will compare the
information reported in its header with the state of its associated session. If they do not
match, the firewall will execute the actions specified in the security policy, which typically
involves dropping the packet and logging the action.
Stateful inspection provides more security than other firewall technology such as packet
filtering because the traffic is examined under the context of the connection and not as
a collection of various packets. By default, the Juniper Networks firewall denies all traffic
in all directions. Then, by using centralized, policy-based management, enterprises can
create security policies that define the parameters of traffic that is permitted to pass from
specified sources to specified destinations.
Secure, reliable WAN connectivity also plays an important role in network-level protection.
By deploying robust virtual private networks (VPNs), remote sites can be securely
connected to other remote sites and to centralized data and applications using highbandwidth shared media such as the Internet. Features such as Auto Connect VPN,
available on select models, can help ease the administration and management of VPNs,
particularly in hub-and-spoke topologies, allowing secure connections to be automatically
set up and taken down without manual configuration.
Protection Against Application-Level Threats
To help block malicious application-level attacks, Juniper Networks seamlessly integrates
intrusion prevention across the entire product line. For central enterprise sites, data center
environments and service provider networks with high volumes of throughput, the Juniper
Networks SRX100, SRX110, SRX210, SRX220, SRX240, SRX550, SRX650, SRX1400,
SRX3000 line and SRX5000 line of services gateways can be deployed for applicationlevel protection.Unmatched security processing power and network segmentation
features protect critical high-speed networks against the penetration and proliferation
of existing and emerging application-level threats. With multiple attack detection
mechanisms, including stateful signatures and protocol anomaly, the SRX Series Services
Gateways perform in-depth analysis of application protocol, context, state and behavior.
Security administrators can deploy Juniper Networks AppSecure capability using deep
inspection to block application-level attacks before they infect the network and inflict
any damages. AppSecure utilizes advanced, high-performance detection mechanisms
integrated with stateful inspection firewall, along with multiple threat inspection
engines operating in parallel to accurately detect advanced persistent threats, including
those found in nested applications within applications. The services that are enabled
by AppSecure include: AppTrack for detailed visibility of application traffic; AppFW
for granular policy enforcement of application traffic; AppQoS to prioritize and meter
application traffic; and AppDoS for greater control over the latest breed of botnet attacks
targeting applications. AppSecure also works with the SRX Series’ integrated intrusion
prevention system (IPS) solution to deliver deeper protection.
Integrated Antivirus Protects Remote Locations
For remote offices or smaller locations with limited IT staff, integration and simplicity are
an absolute must in any security solution. Juniper Networks currently provides on-box or
cloud-based AV protection on the Juniper Networks SRX Series Services Gateways for the
branch. These products combine firewall and VPN capabilities with an antivirus scanning
engine that includes antiphishing, antispyware, anti-adware to provide a comprehensive
security solution in a single device.
These integrated appliances scan for viruses imbedded in both email and Web traffic
by scrutinizing IMAP, SMTP, FTP, POP3, IM and HTTP protocols. They provide the most
advanced protection from today’s fast-spreading worms, viruses, trojans, spyware, and
other malware from damaging the network. With its ability to uncompress files using
common protocols, the engine scans deep inside attachments to detect threats hidden in
multiple levels of compression.
Controlling Access to Known Malware and
Phishing Websites
Employees who access inappropriate websites from the corporate network risk bringing
malicious software into the organization. Worse, their errors in judgment could also
expose the company to litigation for not having adequate controls in place. Juniper
Networks integrated security devices are the ideal solution to help organizations devise
and enforce responsible Web usage policies.
Two approaches are available: external and integrated Web filtering. External Web
filtering, available on all Juniper Networks firewall and VPN devices, redirects traffic
from the device to a dedicated Websense Web filtering server for enforcement of the
organization’s policies. Integrated Web filtering, available on the SRX Series for the
branch, enables enterprises to build their own Web access policies by selectively blocking
access to sites listed in a continuously updated database. Maintained by Websense, a
Juniper Networks security alliance partner, the database lists more than 20+ million URLs
organized into more than 54 categories of potentially problematic content.
Customers can rapidly deploy integrated or external Web filtering using default
configurations based on the Websense database. Web filtering profiles can be customized
by using black lists or white lists, plus a number of predefined and user-defined categories.
Blocking Inbound Spam and Phishing Attacks
Juniper Networks has teamed up with Sophos to leverage their market-leading antispam
solution and reputation service for Juniper’s small-to-medium office platforms to help
limit unwanted emails and the potential attacks they carry. Installed on the Juniper
Networks firewall/VPN gateway, the antispam engine filters incoming email from known
spam and phishing users, acting as a first line of defense. When a known malicious email
arrives, it is blocked and/or flagged so that the email server can take appropriate action.
Integrated antispam is available on the entire SRX Series for the branch.
Boosting Security by Dividing the Network into Multiple
Network Segments
Technologies in the Juniper Networks integrated firewall/VPN, and secure router security
solutions enable users to segment their network into many separate compartments, all
controlled through a single appliance. Administrators can simply segment traffic bound
for different destinations, or they can further divide the network into distinct, secure
segments with their own firewalls and separate security policies.
The firewall/VPN devices support the following virtualization technologies:
• Security Zones: Supported on every product, security zones represent virtual sections of
the network, segmented into logical areas. Security zones can be assigned to a physical
interface or, on the larger devices, to a virtual system. When assigned to a virtual
system, multiple zones can share a single physical interface which lowers ownership
costs by effectively increasing interface densities. Zone policy visibility and integration
with vGW Virtual Gateways.
• Logical Systems (LSYS): Available on the Juniper Networks integrated security
services gateways, logical systems are an additional level of partitioning that creates
multiple independent virtual environments, each with its own set of users, firewalls,
VPNs, security policies, and management interfaces. By providing administrators with
the ability to quickly segment networks into multiple secure environments managed
through a single device, LSYS enables network operators to build multi-customer
solutions with fewer physical firewalls and reduced administrative attention. This
reduces both capital and operational expenses.

Networks are segmented into hierarchies of secure compartments using virtual technology.
• Virtual Routers (VR): Supported on all products, virtual routers enable administrators
to partition a single device so it functions like multiple physical routers. Each VR can
support its own domains, ensuring that no routing information is exchanged with
domains established on other VRs. This enables a single device to support multiple
customer environments, lowering total cost of ownership.
• Virtual LANs (VLAN): Supported on all platforms, VLANs are a logical—not physical—
division of a subnetwork that enables administrators to identify and segment traffic
at a very granular level. Security policies can specify how traffic is routed from each
VLAN to a security zone, virtual system or physical interface. This makes it easy for
administrators to identify and organize traffic from multiple departments and define
what resources each can access.
Comprehensive High Availability Solutions
Ensure Uptime
A security system is only as good as its reliability and uptime. Juniper Networks security
solutions include reliable, high availability systems based Juniper Services Redundancy
Protocol (JSRP) to run on Junos operating system-based products. Firewall, VPN, and IPS
flows can be synchronized between high availability pairs to provide subsecond failover to
a backup device. Configuration options include:
• Active/Passive: Master device shares all network,
configuration setting, and current session information
with the backup so that, in the event of a failure, the
backup can take over in a seamless manner. Juniper

centralized, policy-based control.
• Active/Active: Both devices are configured to be active,
with traffic flowing through each. Should one device fail,
the other device becomes the master and continues
to handle 100 percent of the traffic. The redundant
physical paths provide maximum resiliency and uptime.
High availability configurations maintain
service despite device or link failures.
Device Integration Made Easy
Networks are never static. Potentially costly and time-consuming changes and additions
occur all the time. When the network topology changes, or as new offices, business
partners, and customers are added to the network, network interoperability becomes
especially important. To simplify network integration and help minimize administrative
effort when changes are required, Juniper Networks integrated security solutions can
operate in three different modes:
• Transparent mode affords the simplest way to add security to the network. In
transparent mode, organizations can deploy a Juniper Networks firewall/VPN appliance
without making any other changes to the network: firewall, VPN, IPS, and denial-ofservice (DoS) mitigation functions work without an IP address, making the device
“invisible” to the user.
• Route mode enables the security device to actively participate in network routing by
supporting both static and dynamic routing protocols, including BGP, OSPF, RIPv1,
RIPv2, and ECMP. Route mode enables administrators to quickly deploy multilayer
security solutions with a minimum of manual configuration.
• NAT mode automatically translates an IP address or a group of IP addresses to a single
address to hide an organization’s private addresses from public view.
Juniper Networks integrated security devices support both static and dynamic address
assignment through DHCP or PPPoE, enabling Juniper Networks solutions to operate in
any network environment.
Unbound Scalability
As network requirements continue to evolve, the processing and I/O requirements for
various network devices will also evolve. To meet the demands of ever changing scalability
requirements, the SRX1400, SRX3000 line and SRX5000 line of services gateways
leverage the Juniper Networks Dynamic Services Architecture.
Dynamic Services Architecture enables the most flexible I/O and processing configuration
by supporting service processing cards and I/O cards on the same slot, allowing the highend SRX Series Services Gateways to be configured as a processing-intensive solution or
an I/O-intensive solution and anywhere in between. The SRX3000 line and SRX5000 line
is able to scale performance almost linearly by adding additional network and services
processing cards with very little overhead. This extensive I/O and processing scalability
brought about by Juniper’s Dynamic Services Architecture is only available on the data
center class of SRX Series Services Gateways.
Managing the Network and Security
Unlike solutions that require administrators to use multiple management tools to control
a single device, Network and Security Manager (NSM) enables IT departments to control
the device throughout its life cycle with a single, centralized dashboard. NSM is designed

solutions for network, fault, performance, and change control. By selecting the appropriate
management tool, network administrators can deploy, manage and troubleshoot large
network deployments.
For Low-Cost Rapid Deployment, Drop Ship Devices—
Not Administrators
To avoid the high cost of sending administrators to configure systems at remote sites,
Juniper Networks integrated security devices can be installed by nontechnical users.
With the Network and Security Manager Rapid Deployment functionality, network
administrators do not need to preconfigure the devices or handle them in any way.
At the remote site, the new device simply needs to be cabled up and loaded with a small
configuration file, which a central administrator has either emailed or sent on CD to the
remote location. The initial configuration file establishes a secure connection to Network
and Security Manager which then pushes the complete configuration files to the new device.
