    IP Networks for the cloud, 5G and IoT era:

    IP Network Requirements:
    • Multiples - Capacity and fan-in
    • Superior - Capability and agility
    • Fraction - OpEx and complexity

    Networks of the future must be:

    • Bigger, faster & more efficient
    • Safer
    • More adaptable
    image
    Connecting the Internet of Things - New opportunities, and threats:
    • No perimeter:
      • Large attack surface
      • Countless sources
    • Malicious user traffic:
      • Hackers and cyber criminals
      • Terrorists and anarchists
    • Many vulnerabilities:
      • Hijacked cloud servers, IoT devices
      • Essential services (DNS, AAA, NFV)
    • Distributed DoS attacks:
      • Causing widespread outages
      • Increasing frequency and volume

      Denial of service = no service! Service availability is gated by network security

    Unmitigated DDoS attacks can cause massive outages within hours - Time is of the essence to detect and stop them

    Major DDOS attack on Dyn disrupts AWS, Twitter, Spotify and more - 21 Oct. 2016 by Sebastian
    image
    Cloud and IoT are fueling major DDoS attacks - Security is an ongoing and evolving threat:
    • Increasing scale and complexity:
      • Higher internet upload speeds
      • More connected IoT devices
      • Many vulnerabilities. DDoS as a service
    • Increasing attack frequency:
      • 100G+ attacks are a daily occurrence
      • Bi-weekly attacks in 300 - 600G range
      • Multiple attackers (Mirai, Kaiten, XOR, Spike, ...)

    Mirai: The first open-source IoT botnet:

    • Sep 2016:
      • 600G attack on security expert Brian Kreb's website
      • 1.1T attack on OVH, a French web hosting company
    • Oct:
      • Mirai source code is released in public domain
      • 1T+ flooding attack on DynDNS
    • Nov:
      • Attack on DT, disabling 900,000 home routers

    Terabit DDoS attacks will soon be the norm. Is your network prepared for this?

    DDoS mitigation Present Mode - The network is part of the problem:

    • IP routers backhaul DDoS traffic to scrubbing center
    • Network appliances detect and filter DDoS traffic
    • High cost, partial protection and poor scalability
    image

    Escalating cost of backhaul capacity and scrubbing appliances to mitigate DDoS attacks

    DDoS mitigation Future Mode - The network is part of the solution:

    • Cloud-based DDoS detection and analysis
    • Filtering volumetric DDoS traffic at the IP edge
    • Network-wide protection with superior scalability
    image

    Scalable, distributed solution to mitigate volumetric Distributed Denial-of-Service attacks

    Detecting and mitigating DDoS attacks - Packet inspection and signature detection:

    DDos flows can be detected by inspecting the IP packet payload for tell-tale signature patterns:

    • Conventional IP routers are incapable to look beyond the "5 tuple" IP packet header field
    • DPI appliances can look deeper into the packet, but their forwarding capacity is very limited
    image

    How to mitigate DDoS flooding attacks containing 100,000 of flows?

    Denial of Service attacks: Top 10 threats:

    • UDP amplification-based attacks using "reflection"
    • DNS/NTP reflector attacks:
      • Abuse DNS/NTP protocol aspects to generate a large payload from small requests
      • Use IoT bot-nets to amplify the attack (nature of DDoS)
      • Hard to detect and mitigate. Must be surgically blocked
    image
    Insight driven automation - Growing list of use cases:
    • Automated IP Network Security:
      • Multiple tier 1 SPs - DDoS Attack Mitigation
    • Service automation with dynamic assurance:
      • Multiple tier 1 SPs - Dynamic IP/MPLS services
      • Multiple tier 1 SPs - On-demand IP/MPLS services
    • Multi-dimensional flow steering:
      • Global webscale company - Peering/CDN optimization
      • EMEA content provider - High quality experience
      • APAC tier 1 ISP - High quality OTT experience

    • Customer are using MPLS in order to: Connect their physical locations, avoiding sending latency/packet-loss sensitive applications over the unpredictable Internet.

    • Why should a customer consider CATO cloud as an MPLS alternative:
      • Need to reduce MPLS costs and/or increase network capacity but without compromising on quality and availability.
      • Need a managed service that is agile, customer-centric, and tailored to the needs of the digital business.
      • Need to optimize and secure access to cloud data-centers and/or cloud applications.

    • Natively-integrated, global connectivity for mobile, allowing optimized and secure access enterprise resources and to the Internet offering does CATO have for mobile workforce.

    • Cato's SD-WAN is delivered as a cloud
      service with a private backbone for global connectivity, integrated security and with cloud and mobile access is Cato's SD-WAN different than other SD-WANs.

    • Uses link profiling to identify and
      report on blackouts as well as brownouts (quality degradation) makes Cato's ILMM (Intelligent Last Mile Management) service unique.

    • Cato built its own NGFW which is natively integrated into its service is NGFW used in Cato's security stack.

    • It governs both North-South (Internet) and East-West (WAN) traffic, rather then just North-South is Cato's integrated NGFW unique compared to
      other gateway firewalls.

    • The capabilities are included in Cato's security stack:
      • Intrusion Prevention System (IPS) as a Service
      • Known and zero-day malware prevention
      • Application aware access control for both WAN and Internet

    • Natively-integrated TCP Proxy is wan optimization technology provided by CATO cloud to maximize file transfer speed.

    • Cato Socket edge SD-WAN appliances do CATO customers use.

    • Simply contact Cato's partner and adjust the subscription Cato's customers do when grow in users, traffic, or sites.

    • CFO must reduce global MPLS wan connectivity costs. CATO can help with using last-mile Internet together with Cato Cloud.

    • CIO need more bandwidth in MPLS-based network with the same budget. Using last-mile Internet together with Cato can help keep the same spend and increase capacity.

    • Have 20 offices with Fortinet UTMs which are about to expire. Cato's FWaaS can easily replace all UTMs with security as a service, also transitioning from CAPEX to OPEX.

    • Cato is the ONLY vendor that can address regional SD-WAN needs and also security, cloud access and mobile access needs - all in one cloud-service platform.

    • Cato uses multiple SLA-backend backbone connections between all its PoPs, and proprietary routing software that always chooses the optimal path for each packet in real-time.

    • For the last mile, Cato supports aggregation of multiple Internet links (fiber, DSL, cable, and LTE) to establish a highly available connection to Cato's Cloud. On middle-mile, provide a 5-9's SLA similar to MPLS providers.
