Back to segmented networks?

Organisations need to move back to the days of segmented networks, to gain full visibility of network traffic and combat growing threats inside their networks, says JOHN WARD, Systems Engineer, Africa at Fortinet.

The risks inside a corporate network are usually far greater than organisations think. In fact, there may be more threats within an organisation’s perimeter defences than outside of them.

Mobile devices used in unsecured environments may bring malware directly into the core networks. Cybercriminals who gain access to the network have free access to everything once they bypass the perimeter firewall. Internet of Things devices and cloud connected printers connected to the network are typically left unsecured and unmanaged.

In addition, a poorly managed network that offers little or no visibility typically performs badly, impacting productivity and efficiency and the overall cost of doing business. This too, should be considered a serious business and productivity risk.

Information security professionals and risk managers are well aware that an ‘insider threat’ exists, but typically don’t have the resources to effectively mitigate the risk, and often they do not realise how network configuration impacts their threat exposure. Most organisations put in bare minimum perimeter firewalls to meet auditor requirements, and run flat layer 2 networks for cost control and ease of administration.

In an environment fraught with increasingly advanced threats, this architecture can prove to be a costly mistake. Consider for one minute that any users’ pc could unknowingly be directly tethered to the internet via their phone yet still be connected to the internal LAN.

In many consultations with potential clients, we have discovered perimeter firewalls up to ten years old and long out of their support contracts, still in place as the organisation’s only network defence. When we put FortiGate behind these incumbent firewalls into the core to analyse the state of the network, we almost always turn up issues the organisation knew nothing about.

There may be broadcast storms impacting users across the network; there may be old applications still running that IT management thought were long since phased out; there are frequently configuration issues and legacy systems impacting the overall network performance and increasing its risk profile.   At least 60% of the time, when organisations get their first true view of network traffic, they are unpleasantly surprised.

To address the threats inside the network and optimise network performance, organisations need to move away from the flat layer and back to the segmented network model of the past. Only this time, they need to lock down the segmented network without compromising performance, for example by installing Fortinet’s FortiASIC powered internal segmentation firewalls.

Deployed transparently in L2 mode or bump in wire and ASIC driven wire speed capable, these do not require extensive network overhauls. They simply plug into the network to deliver visibility into network traffic as well as application control, web filtering, advanced threat protection, mobile security and antivirus.

However, it is crucial that these internal segmentation firewalls do not cause bottlenecks that slow down the overall performance of the network. An effective internal segmentation firewall should support wire-speed internal traffic with multi-tens-gigabit performance, sitting at strategic choke points of the internal network. There, it provides policy-driven segmentation, instant visibility of traffic in and out of the network asset and real time protection of the asset, serving as an important component of the overall security suite. If required, these firewalls can even provide a secure ring around the legacy equipment to assure security and control.

With segmentation and full visibility, organisations are able to significantly improve governance and risk management, monitor and manage threats in real time, and optimise network performance by discovering where to clean up the network, or reconfigure and remove redundant systems.

Veeam passes $1bn, prepares for cloud’s ‘Act II’

Leader in cloud-data management reveals how it will harness the next growth phase of the data revolution, writes ARTHUR GOLDSTUCK

Veeam Software, the quiet leader in backup solutions for cloud data management,has announced that it has passed $1-billion in revenues, and is preparing for the next phase of sustained growth in the sector.

Now, it is unveiling what it calls Act II, following five years of rapid growth through modernisation of the data centre. At the VeeamON 2019conferencein Miami this week, company co-founder Ratmir Timashev declared that the opportunities in this new era, focused on managing data for the hybrid cloud, would drive the next phase of growth.

“Veeam created the VMware backup market and has dominated it as the leader for the last decade,” said Timashev, who is also executive vice president for sales and marketing at the organisation. “This was Veeam’s Act I and I am delighted that we have surpassed the $1 billion mark; in 2013 I predicted we’d achieve this in less than six years. 

“However, the market is now changing. Backup is still critical, but customers are now building hybrid clouds with AWS, Azure, IBM and Google, and they need more than just backup. To succeed in this changing environment, Veeam has had to adapt. Veeam, with its 60,000-plus channel and service provider partners and the broadest ecosystem of technology partners, including Cisco, HPE, NetApp, Nutanix and Pure Storage, is best positioned to dominate the new cloud data management in our Act II.”

In South Africa, Veeam expects similar growth. Speaking at the Cisco Connect conference in Sun City this week, country manager Kate Mollett told Gadget’s BRYAN TURNER that the company was doing exceptionally well in this market.

“In financial year 2018, we saw double-digit growth, which was really very encouraging if you consider the state of the economy, and not so much customer sentiment, but customers have been more cautious with how they spend their money. We’ve seen a fluctuation in the currency, so we see customers pausing with big decisions and hoping for a recovery in the Rand-Dollar. But despite all of the negatives, we have double digit growth which is really good. We continue to grow our team and hire.

“From a Veeam perspective, last year we were responsible for Veeam Africa South, which consisted of South Africa, SADC countries, and the Indian Ocean Islands. We’ve now been given the responsibility for the whole of Africa. This is really fantastic because we are now able to drive a single strategy for Africa from South Africa.”

Veeam has been the leading provider of backup, recovery and replication solutions for more than a decade, and is growing rapidly at a time when other players in the backup market are struggling to innovate on demand.

“Backup is not sexy and they made a pretty successful company out of something that others seem to be screwing up,” said Roy Illsley, Distinguished Analyst at Ovum, speaking in Miami after the VeeamOn conference. “Others have not invested much in new products and they don’t solve key challenges that most organisations want solved. Theyre resting on their laurels and are stuck in the physical world of backup instead of embracing the cloud.”

Illsley readily buys into the Veeam tagline. “It just works”. 

“They are very good at marketing but are also a good engineering comany that does produce the goods. Their big strength, that it just works, is a reliable feature they have built into their product portfolio.”

Veeam said in statement from the event that, while it had initially focused on server virtualisation for VMware environments, in recent years it had expanded this core offering. It was now delivering integration with multiple hypervisors, physical servers and endpoints, along with public and software-as-a-service workloads, while partnering with leading cloud, storage, server, hyperconverged (HCI) and application vendors.

This week, it  announced a new “with Veeam”program, which brings in enterprise storage and hyperconverged (HCI) vendors to provide customers with comprehensive secondary storage solutions that combine Veeam software with industry-leading infrastructure systems. Companies like ExaGrid and Nutanix have already announced partnerships.

Timashev said: “From day one, we have focused on partnerships to deliver customer value. Working with our storage and cloud partners, we are delivering choice, flexibility and value to customers of all sizes.”

‘Energy scavenging’ funded

As the drive towards a 5G future gathers momentum, the University of Surrey’s research into technology that could power countless internet enabled devices – including those needed for autonomous cars – has won over £1M from the Engineering and Physical Sciences Research Council (EPSRC) and industry partners.

Surrey’s Advanced Technology Institute (ATI) has been working on triboelectric nanogenerators (TENG), an energy harvesting technology capable of ‘scavenging’ energy from movements such as human motion, machine vibration, wind and vehicle movements to power small electronic components. 

TENG energy harvesting is based on a combination of electrostatic charging and electrostatic induction, providing high output, peak efficiency and low-cost solutions for small scale electronic devices. It’s thought such devices will be vital for the smart sensors needed to enable driverless cars to work safely, wearable electronics, health sensors in ‘smart hospitals’ and robotics in ‘smart factories.’ 

The ATI will be partnered on this development project with the Georgia Institute of Technology, QinetiQ, MAS Holdings, National Physical Laboratory, Soochow University and Jaguar Land Rover. 

Professor Ravi Silva, Director of the ATI and the principal investigator of the TENG project, said: “TENG technology is ideal to power the next generation of electronic devices due to its small footprint and capacity to integrate into systems we use every day. Here at the ATI, we are constantly looking to develop such advanced technologies leading towards our quest to realise worldwide “free energy”.

“TENGs are an ideal candidate to power the autonomous electronic systems for Internet of Things applications and wearable electronic devices. We believe this research grant will allow us to further the design of optimized energy harvesters.”
