Suricata is multi threaded. This means you can run one instance and it will balance the load of processing across every processor on a sensor Suricata is configured to use. This allows commodity hardware to achieve 10 gigabit speeds on real life traffic without sacrificing ruleset coverage.
The organisers, the thought leaders and exhibiting organizations, like Telesoft are here to provide answers to the questions asked last year. Not quick off the cuff pontifications but real, researched, and actionable solutions. Over the 4 days, over 40,000 attendees experienced keynotes, peer-to-peer sessions, track sessions, tutorials and seminars all telling the same story, innovation and collaboration are going to shape the future of the cyber security industry.
One of the key points of Amit’s keynote was the need for comprehensive visibility of our environments. When the threat is unknown, or zero-day, one option for detection is analysis of traffic for anomalies. Massive traffic volumes inside ultra-scale data centres mean that detailed inspection of every packet would require a doubling of processing capacity. The commonly taken approach is to collect information on each data session or flow, and analyse flow records for unusual behaviour or anomalies, indicating a potential attack or infection.
It is not news that to make measurable improvements to network data security, organisations need to invest in the most current tools and share key knowledge, Flocon 2016 featured a full technical programme which not only highlighted some of the most critical issues surrounding analytics but also outlined actionable solutions. We fielded a number of questions from delegates regarding the growth of external and internal network data, what to do with that information and how it is now the ‘insider threat’ that poses the most risk. The fast paced nature of cybercrime means that cyber security professionals need to find a way to match the threat actors pace, to ensure that threat detection can be turned in to quick incident response.

A signature based IDS, such as Suricata, monitors packets on the network and compares them against a database of signatures or attributes from known malicious threats. Multi-threading and load balancing across CPU cores provides performance gains, however, one of the largest CPU consumers is signature scanning, which can consume up to 80% of CPU load. By offloading signature scanning to an accelerator card, cost effective IDS systems can be built for breach detection and forensics in the network core.
The MPAC-IP 7000 series features variable offset 7 layer deterministic pattern matching at line rate and controlled using Telesoft’s rapid development API, both our 100GbE and 4x10GbE solutions allows operators to maintain ultra-high-speed links ensuring high-performance, security and compliance.
Financially motivated hackers look to exploit vulnerable networks to steal data, money, or disrupt network operations for those willing to pay for the service. It’s no longer just hobbyist hackers looking to infiltrate networks for fun. If IDS and IPS systems, a vital component of any network security architecture, become saturated any worms, spyware, or disruptive packets can bypass security measures entirely, infiltrating the network and causing damage whilst remaining undetected. At best, with fail-closed IPS, the network is disrupted. At worst, your network is the latest to be featured in the news for being hacked.
The obvious advantages of an NFV network architecture are reduced capital expenditure (CAPEX) and operating expenditure (OPEX). Whereas the old paradigm required bespoke hardware devices for each network function – hardware devices that quickly became obsolete as average hardware capabilities surpassed them – NFV allows network functions to be virtualised and run on commercial off the shelf (COTS) servers.
To reduce operating expenditure (OPEX) and minimise rack space usage hardware accelerator cards can be implemented into existing Commercial off the Shelf (COTS) servers or integrated into new systems. Offloading processing to a hardware accelerator card, such as the MPAC-IP 7000 Series from Telesoft, enables the host COTS server to maximise processing power for third party applications without the need for an expensive overhaul of existing infrastructure. Resources can then be freed up and re-purposed or used to extend processing capabilities, reducing capital expenditure (CAPEX).
