This includes the Internet edge, perimeter, endpoint, and data center (including the DMZ). This “outside-in” approach has been based on the concept that companies can control clearly defined points of entry and secure their valuable assets. The strategy was to build a border defense as strong as possible and assume nothing got past the firewall.As organizations grow and embrace the latest IT technology such as mobility and cloud the traditional network boundaries are becoming increasingly complex to control and secure. There are now many different ways into an enterprise network.Not long ago, firewall vendors markedthe ports on their appliances “External” (untrusted) and “Internal” (trusted). However, advanced threats use this to their advantage because, once inside, the network is very flat and open. The inside of the network usually consists of non security-aware devices such as switches, routers, and even bridges. So once you gain access to the network as a hacker, contractor, or even rogue employee, then you get free access to the entire enterprise network including all the valuable assets. The solution is a new class of firewall –Internal Segmentation Firewall (ISFW),that sits at strategic points of the internalnetwork. It may sit in front of specific serversthat contain valuable intellectual property ora set of user devices or web applicationssitting in the cloud.Once in place, the ISFW must provideinstant “visibility” to traffic traversing intoand out of that specific network asset. Thisvisibility is needed instantly, without monthsof network planning and deployment.Most importantly the ISFW must alsoprovide “protection” because detection isonly a part of the solution. Sifting throughlogs and alerts can take weeks or months.The ISFW needs to deliver proactivesegmentation and real-time protectionbased on the latest security updates.Finally, the ISFW must be flexible enoughto be placed anywhere within the internalnetwork and integrate with other parts of theenterprise security solution under a singlepane of management glass. Other securitysolutions can also provide additional visibilityand protection. This includes the emailgateway, web gateway, border firewalls,cloud firewalls, and endpoints. Further,Internal Segmentation Firewalls need toscale from low to high throughputs allowingdeployment across the global network.KEY REQUIREMENTSn COMPLETE PROTECTION –Continuous inside-out protectionagainst advanced threats with asingle security infrastructuren EASY DEPLOYMENT –Default Transparent Mode meansno need to re-architect thenetwork and centrally deployedand managedn HIGH PERFORMANCE –Multi-gigabit performance supportswire speed east-west trafficINTERNAL NETWORKCybercriminals are creating customized attacks to evade traditional defenses, and once inside, to avoid detection and enable egress of valuable data. Once inside the network there are few systems in place to detect or better still protect against APT s. It can be seen from the threat life cycle in Figure 1 that once the perimeter border is penetrated, the majority of the activity takes place inside the boundary of the network. Activities include disabling any agent-based security , updates from the botnet command, and control system, additional infection/recruitment and extraction of the targeted assets.THE ANSWER IS A NEW CLASS OF FIREWALL –INTERNAL SEGMENT A TION FIREWALL (ISFW)Most firewall development over the past decade has been focused on the border, the Internet edge, perimeter (host firewall), endpoint, data center (DMZ), or the cloud. This started with the stateful firewall but has evolved to include Unified Threat Management (UTM) for distributed networks, which brought together the firewall, intrusion detection, and antivirus. Later came the Next Generation Firewall (NGFW), which included intrusion prevention and application control for the Internet edge. More recently because of the huge increase in speeds, Data CenterFirewalls (DCFW) have arrived to provide more than 100 Gbps of throughput. All of these firewalls have in common an approach designed to protect from the “outside-in.”For rapid internal deployment and protection, a new class of firewall is required – Internal Segmentation Firewall (ISFW). The Internal Segmentation Firewall has some different characteristics when compared to a border firewall. The differences are laid out in figure 2.14DisposalThreat Production+ ReconThreat VectorExtractionScan for vulnerabilities Design phishing emails Customize malware, etc.ExternalPackage &Encrypt StageFIGURE 1 – ADVANCED THREAT LIFE CYCLEFIGURE 2 – FIREWALL TYPE DIFFERENCESTHE ISFW NEEDS TO PROVIDE COMPLETE PROTECTIONThe first element of security is visibility. And visibility is only as good as network packet knowledge. What does a packet stream look like for a specific application, where did it come from, where is it going, even what actions are being taken (download, upload…).The second and equally important element is protection. Is the application, contentor actions malicious? Should this type of traffic be communicating from this set of assets to another set of assets? While this is very difficult across different contentand application types, it is an essentialpart of the ISFW. The ability to detect a malicious file, application, or exploit gives an enterprise time to react and contain the threat. All of these protection elements must be on a single device to be effective.Both visibility and protection are heavily reliant on a real-time central security threat intelligence service. A question that always needs to be posed – how good is the visibility and protection? Is it keeping up with the latest threats? That’s why all security services should be measured on a constantbasis with 3rd party test and certificationservices.THE ISFW NEEDS TO PROVIDE EASYDEPLOYMENTThe ISFW must be easy to deploy andmanage. Keeping it simple for IT meansbeing able to deploy with minimumconfiguration requirements and withouthaving to re-architect the existing network.The ISFW must also be able to protectdifferent types of internal assets placed atdifferent parts of the network. It could be aset of servers containing valuable customerinformation or a set of endpoint devicesthat may not be able to be updated with thelatest security protection.Additionally, the ISFW must be able tointegrate with other parts of the enterprisesecurity solution. Other security solutionscan also provide additional visibility andprotection. This includes the email gateway,web gateway, border firewalls, cloudfirewalls, and endpoints. This all needs tobe managed with a ‘single pane of glass’approach. This allows security policies to beconsistent at the border, inside the network,and even outside the network in clouds.Traditional firewalls are usually deployedin routing mode. Interfaces (ports) are welldefined with IP addresses. This often takesmonths of planning and deployment. Thisis valuable time in today’s instant cyberattack world. An ISFW can be deployedin the network rapidly and with minimumdisruption. It must be as simple as poweringon a device and connecting. It must betransparent to the network and application.THE ISFW NEEDS TO PROVIDE WIRE-SPEED PERFORMANCEBecause internal segmentation firewalls aredeployed in-line for network zoning, theymust be very high performance in order tomeet the demands of internal or “east-west”traffic, and to ensure they do not becomea bottleneck at these critical points. Unlikefirewalls at the border that deal with WideArea Network (WAN) access or Internetspeeds of less than 1 gigabit per second,internal networks run much faster – multi-gigabit speeds. There, ISFWs need tooperate at multi-gigabit speeds and be ableto provide deep packet/connect inspectionwithout slowing down the network.REQUIREMENTSA FLEXIBLE NETWORK OPERATING SYSTEMAlmost all firewall “deployment modes” require IP allocation and reconfiguration of the network. This is known as network routing deployment and provides traffic visibility and threat prevention capabilities. At the other end of the spectrum is sniffer mode, which is easier to configure and provides visibility, but does not provide protection.Transparent mode combines theadvantages of network routing and sniffer modes. It provides rapid deployment and visibility plus, more importantly, protection. The differences are summarized in Figure 3.FIGURE 3 – FIREWALL TYPE DIFFERENCESA SCALABLE HARDWARE ARCHITECTUREBecause internal networks run at much higher speeds the ISFW needs to be architected for multi-gigabit protection throughput. Although CPU-only based architectures are flexible they become bottlenecks when high throughput isrequired. The superior architecture still uses a CPU for flexibility but adds custom ASICs to accelerate network traffic and content inspection.Because the ISFW is deployed in closer proximity to the data and devices, it may sometimes need to cope with harsher environments. Availability of a moreruggedized form factor is therefore another requirement of ISFWs.with cloud-based sandboxing, allowing for the enforcement of policies thatcomplement standard border firewalls. This real-time visibility and protection is critical to limiting the spread of malware inside the network.NETWORK WIDE ISFW DEPLOYMENT EXAMPLEMost companies have set up border protection with firewalls, NGFWs, and UTMs. These are still critical parts ofnetwork protection. However, to increase security posture, Internal Segmentation Firewalls can be placed strategically internally. This could be a specific set ofendpoints where it is hard to update security or servers where intellectual property is stored.SEGMENT ISFW DEPLOYMENT EXAMPLEThe ISFW is usually deployed in the access layer and protects a specific set of assets. Initially the deployment is transparent between the distribution and access switches. Longer term the integrated switching could take the place of theaccess and distribution switch and provideadditional physical protection.DEPLOYMENT (ISFW) DEPLOYMENTNETWORK SEGMENTATION –HIGH SPEED INTEGRATED SWITCHING An evolving aspect of transparent mode is the ability to physically separatesubnetworks and servers via a switch.Firewalls are starting to appear on the market with fully functional, integrated switches within the appliance. These new firewalls, with many 10 GbE port interfaces, become an ideal data center “top-of-rack” solution, allowing servers to be physically and virtually secured. Also, similar switch-integrated firewalls with a high density of 1 GbE port interfaces become ideal for separation of LAN subsegments. ISFWs should be able to fulfill both of these roles, and as such should ideally have fullyfunctional, integrated switching capabilities.REAL-TIME SECURITYInternal Segmentation Firewalls must be able to deliver a full spectrum of advanced security services, including IPS, application visibility, antivirus, anti-spam, and integrationCopyright © 2016 Fortinet, Inc.

Sunrise Blvd., Suite 430Sunrise, FL 33323Tel: +1.954.368.9990ENHANCING ADVANCED THREA T PROTECTION WITH INTERNAL VISIBILITYA proper approach to mitigating advanced threats should include a continuous cycle of prevention, detection, and mitigation. Very typically a next-generation firewall would serve as a key foundation of the prevention component, enabling L2/L3 firewall,intrusion prevention, application control and more to block known threats, while passing high-risk unknown items to a sandbox for detection. But with NGFW’s deployed traditionally at the network edge, this only provides partial visibility into the attack life cycle by primarily observing ingress and egress activity.Deployment of an ISFW can providemore complete visibility into the additional internal activity of the hackers once they’ve compromised the edge. Lateral movement can account for a significant portion of the malicious activity as the hackers try to identify valuable assets and extract data,and having a complete picture of both internal and edge activity enhances allphases of a complete ATP framework. With internal network traffic often being several times the bandwidth of edge traffic, an ISFW can provide many more opportunities to limit the spread of the compromise from known techniques and more high-risk items to be passed to sandboxes for deeper inspection.CONCLUSIONAdvanced Threats are taking advantage of the flat Internal network. Once through the border defense there is little to stop their spread and eventual extraction of valuable targeted assets. Because traditional firewalls have been architected to slower speeds of the Internet edge it’s hard to deploy these security devices internally. And firewall network configuration deployments (IP addresses) take a long time to deploy.Internal Segmentation Firewalls are a new class of firewall that can be deployed rapidly with minimum disruption while keeping up the multi-gigabit speeds of internal networks. Instant visibility and protection can be applied to specific parts of the internal network.FIGURE 5 – ADVANCED THREAT PROTECTION (ATP) FRAMEWORK。
