Software-Defined Networks can shape data packet routes to address border-control regulation and data-privacy fears, claims Dan Pitt, Executive Director, Open Networking Foundation
What is the best way to protect data? Concentrate it? Or spread it about?
If you write your memoirs and lock them in a safe for future generations, then the house could burn down and they are gone forever. But if you publish and sell them, your memoirs could survive a world war.
The Internet was designed to survive a world war by maximizing redundancy – data was not restricted to specific routes but would find its way to the destination by whatever routes were available. This thinking lives on in cloud computing, with redundancy and data backups spread across multiple regions simultaneously to defend against data loss or localized hang-ups.
The problem is that data protection can mean protecting data from loss – in which case the more copies spread about the better – or it can mean keeping data private – in which case the fewer copies the better. IT grew up in closed physical networks linking initially unreliable hardware, so the legacy priority is for redundancy, and remote back ups, and this is reflected in the way the Cloud is developing. Legislators, however, have to reconcile the benefits of free information flow with the values of privacy and individual liberty.
Data sovereignty and border control
“Trans-border data flow” is the legal term for data being stored, transmitted, or processed outside a nation’s borders. The controversial USA PATRIOT Act of 2001 gave US law enforcement agencies powers to intercept data way beyond what is acceptable in some other countries. Indonesia has strict “data sovereignty” laws that require personal information to be kept inside the country’s physical borders. The privacy value of personal data can vary between legislations: sexual orientation or religious beliefs may not be sensitive issues in one country, but could lead to persecution or even imprisonment in another.
There are several approaches to addressing this problem. Strong encryption and ways to hide the identity of data in the Cloud may provide enough protection to satisfy the individual, but they may not comply with data sovereignty legislation – bearing in mind the possibility of other national governments applying their full weight to crack sensitive data. Another method is a hybrid cloud approach, so that critical data is housed and processed on-site while less sensitive data is managed and processed on the cloud architecture.
But knowing where data is being stored is not the whole story. Personal data may be keyed into a PC with some confidence when you know it is being transmitted to a trusted Cloud service, but how does it get there? As mentioned above, the Internet was designed for maximum redundancy and flexibility, so that packets are given a destination, but no restriction on how they reach that destination. The routing is not entirely arbitrary – IP will favour an efficient pathway but heavy traffic, router outages, and line breaks can all impact the actual route taken.
So, even if the start and end point are in the same country, you cannot be certain that the data might not cross and re-cross national borders somewhere along the way. In practical business terms this might not seem an issue, but in terms of legislative compliance it could prove serious.
How could this problem be resolved without a massive rebuild of the global network infrastructure to ensure that every point where data lines cross national borders? Software-Defined Networks could be the answer.
Software-Defined Networks (SDN)
Software-defined networking allows network operators to program a network’s control plane from a central interface, using ordinary programming methods. Instead of having to go into the physical network and reconfigure boxes, general instructions can be sent out across the entire network, or subsections of the network, using the OpenFlow protocol. These instructions are introduced by software written to the aforementioned API, making the network into “a software-defined network”.
Whereas in a normal router or switch the fast packet forwarding (data path) and the high-level routing decisions (control path) happen in the same device, with OpenFlow-enabled switches these two functions are separated: the data path still resides on the switch, while the high-level routing decisions are moved to a separate controller. OpenFlow switch and controller communicate via the OpenFlow protocol, an industry standard under the auspices of the Open Networking Foundation.
OpenFlow-enabled switches and controllers are already available from multiple vendors, with vendors worldwide increasingly recognizing and supporting the standard. Incorporating these switches into a network makes it easy to adjust routing and switching protocols and optimize performance, and also to provide a way to address specific issues such as high security networking and border control.
On an OpenFlow-enabled network, packets containing personal data that should not cross national borders could be identified and instructions given for them to be routed only via national lines. More detailed routing protocols could increase the number of qualifiers and provide more detailed instructions on permitted and forbidden data pathways. Whatever the need, it can be programmed and updated from a consistent wide view, to keep abreast of regulations as well as public concerns about privacy.
SDN, as a concept, includes more than the OpenFlow protocol. It embraces programmable interfaces, virtualization, and orchestration – with companies offering proprietary SDN solutions – but the significance of OpenFlow is that it is a vendor-agnostic standard. As more OpenFlow switches are installed regardless of manufacturer, the ability to program the network will spread across the network. Add one at a time to an existing network to gradually make it more a more programmable.
OpenFlow is the way forward, even though there is much work to be done to fully exploit the benefits of SDN. Software-based policies can govern everything from border control to energy saving. The existence of a separate data plane makes it possible to program the network from a central console, but initially this is still a relatively piecemeal process, like writing a computer program in machine language. But OpenFlow as a standard lays the foundation for a new network software discipline, working towards a high-level language that will make networks as readily programmable as a PC – allowing fundamental changes such as border controls to be selectively broadcast right across the network with just a few keystrokes or automated routines.
The opportunity for carriers
Border control could be a significant market differentiator for Cloud or network services. Organisations severely restricted by privacy legislation cannot enjoy the full benefits of free-flowing data and the efficiencies of the Cloud because of the need to comply, and prove compliance, with the demands of data sovereignty. A service provider that can offer guarantees that data will never stray across certain boundaries, or enter forbidden zones, would find a ready market.
The opportunity is open-ended: what other services could benefit from an ability to shape the logical network structure and routes across it? Low latency is a hot issue in financial circles: although the most critical ultra-low-latency demands can only be met by providing dedicated contention-free channels, there is an equal need to multicast time-sensitive data such as prices to multiple customers, where the critical issue is not so much how quickly it gets there as making sure every customer gets it at exactly the same Instant.
SDN is widely recognized as the future of networking – IDC predict it to be worth £1.3 billion by 2016 – but it is a future that starts right now, with industry-standard OpenFlow-enabled switches available from all the top vendors. As it spreads, it increasingly allows the network provider to reshape their network as a logical structure and to seek new ways to increase efficiency, offer better quality of service, and rapidly explore new service opportunities.

How to ensure you bullet proof your IT in a hybrid finance workplace
By Caleb Mills, Chief Technical Officer at Doherty Associates outlines the dangers faced by finance and private equity firms when it comes to IT infrastructure in a pandemic. Caleb warns that maintaining security is critical as firms continue to work remotely in the current lockdown while making plans to return to the new blended workplace in 2021.
2020 was a year of rapid change – for the technology sector in particular. Virtually overnight, IT firms had to meet the growing demands of many businesses accelerating their technology plans in a bid to stay ahead of the new virtual business environment we suddenly found ourselves in. Covid-19 forced many organisations to automatically relax their security policies so that employees could operate in the remote-only world which followed the UK’s first national lockdown in March.
Can personal devices ever be compliant?
When the announcement of the first March lockdown was made, employees were sent home to work, and largely did so on their personal devices; home PCs, personal mobile devices or shared laptops. Compliance calls for organisational data to be encrypted and kept private, access to be audited and for its transmission to be only over secure channels. Many of these requirements are not met if the use of personal devices is allowed carte blanche – so it’s very likely that some firms are falling short of their compliance obligations.
Added to this is the fact that many employees do not want to allow their organisation to install management software, enforce policies, or limit their freedom on the use of personal devices. They may feel that their company is infringing personal liberties or ‘spying on them’. The most simple and effective (yet costly) solution is to issue company devices for all staff – although there may be some resistance from some to having two devices.
There is an option for controlling company data on personal devices that can satisfy some compliance requirements. Technologies now exist to allow organisational data to be kept in a separate virtual container on the device where policies around encryption and such can be enforced without contravening your employees’ privacy. The company portion of the device can be kept in a secure bubble, without enforcing rules or infringing on individual’s freedom with their own personal devices.
New risks and responsibilities
The accelerated adoption of remote working has meant many risk and compliance teams are still rushing to catch up. Many firms have not thoroughly identified the risks associated with remote or hybrid working, which continue to evolve as the constant demands for businesses change. Even those who have identified risks are likely only considering the ones they understand. In many cases, compliance teams need assistance from a cyber security expert who can help define the risks they are not aware they are taking. An expert will understand the wide and varied attack vectors and provide context and insight into how they could impact risk. The changing environment might call for updates to your IT use policy, cyber security policy, or other IT related policies.
Navigating risk and liability
The approach for managing risk must start by having a clear understanding of what your organisation’s risk appetite is. It is not possible to mitigate or eliminate all risks – there will always be some residual risk and it is important for your organisation to know what level of risk it is willing to accept.
When creating treatment plans for each of your risks, the business should consider the many different angles for controlling and mitigating. There are many technical controls which can enforce your policies, but often organisational controls such as processes or workflows can be just as effective. Choosing to adopt a program like Cyber Essentials can help to ensure that your organisation meets certain requirements. Even the very low bar of its framework can help you to ask pertinent questions about your organisation’s security posture.
Changing security boundaries
In days gone by, businesses took some comfort from knowing they had a secure network. They invested in firewalls to build a border around their network, and they trusted workers and the data they accessed to be protected against security threats. Now, many things have changed.
Data is no longer kept solely on servers in the office, it’s now stored largely in the cloud. And, thanks to Covid-19, many users are now operating outside of this safe and secure network too. The net effect of these two key changes is that the approach of building a highly secure boundary around your network no longer delivers the desired results. The post-pandemic workplace, even more so in finance and private equity, needs to be productive and secure from anywhere in the world.
The modern hacker is not just focused on defeating a firewall – they want to steal your firm’s data – and the way they achieve that is typically to hijack an individual’s identity. Modern security now focuses on protecting the data and the identity of workers by using multiple layers of security controls. This multi-layer, or “onion” approach, works on the assumption that a determined attacker can breach anyone or two layers of security protection. To keep your organisation protected, you should have multiple security controls in place to ensure coverage to help keep your environment safe.
Securing and supervising data rooms in a hybrid world
Data rooms provide a critical function by allowing third party organisations to securely access confidential data, so it’s important that the sensitivity of this is considered before embarking on any data room project. Appropriate policies about how the data should be accessed and used can then be enforced by the technology, and these clearly defined policies will allow for tightly configured security controls to limit access appropriately.
For example, data room guests might be allowed to view documents, but prevented from downloading them or copying and pasting content from them. Modern capabilities even include the ability to “timebomb” documents – for example to block access to documents after an NDA has expired.
Finally, consider taking Cyber Insurance. This can provide help with investigations, guidance on reporting to the ICO, help with public relations and communications, and help cover other expenses incurred as part of a cyber event.
The ongoing events of 2020 have changed the way we work forever. New risks and opportunities have continued to emerge through this period, and it’s ever more apparent that the world will never go back to how it worked before. Hybrid working is here to stay so we need to understand the implications and take appropriate steps to ensure we meet our compliance obligations and control risk exposure through a mixture of controls to stay ahead of the game.
Fraud prevention and user experience: how finance institutions can navigate the increasingly complex digital challenge
By Frank Teruel, Chief Operating Officer at Adara.
Well, here we go again. As Covid-19 cases continue to surge and local officials impose restrictions, brick and mortar companies are once again limited in their ability to deliver their services forcing them to double down on their remote location strategies. From curbside pickup, to Uber eats, to an “Amazon Prime” Christmas, the surge in the last 90 days has exacerbated an already difficult business environment. And banking has been no exception. In fact, the consequences have been more significant given the nature of in-person banking…just imagine the difficulties inherent in bringing that service curbside. So, what exactly has the pandemic done to banking?
With in-branch services limited, less digitally-savvy, first time, digital customers have made the jump to online banking products like Klarna for real-time loans, and digital-only bank account offerings like Starling Bank, Atom Bank, and Monzo. The move has been a digital consumer bonanza for online financial institutions which, while happy with the new customers, are left with the daunting task of determining who they are and whether to trust them.
Who are these people?
Unquestionably, the transition to digital banking has brought positive benefits to first-time users such as greater convenience and transparency, but it has also resulted in a less than desirable outcome: increasing levels of fraud and sophistication in attacks. The reality is that many of these nascent digital customers have very little on-line transaction history and virtually no digital identities as a reference point for identity and verification. Consequently, with more and more of them moving their banking online, traditional methods of determining “who is on the other end of a transaction” have been tested, and in many cases become less effective or completely obsolete. And here’s the rub; with little to no digital identities, limited transaction history, and never before seen devices, financial organisations are defaulting to more draconian verification methods…stepping up customers, challenging them with KYC questions, and generally increasing transaction friction.
Go easy on them
Yet, before we castigate the institutions in question, a degree of understanding is warranted. After all, the tsunami of new online transactions represents a significant challenge. And what’s a bank to do? If a bank falsely deems a transaction fraudulent, they are ruining a customer’s on-line experience by creating unnecessary friction which predictably leads to transaction abandonment. On the other hand, if the bank defaults to no friction and allows all of these new transaction to run, it could be a fraudster’s paradise…”free loans, credit cards, and other financial instruments on isle 3!” So, determining the person on the other end of the transaction is paramount to a customer’s experience as well as the future success of a financial institution in maintaining account holders and preventing fraud losses.
Fraud fighting is a full-time, real-time business…and it isn’t cheap!
Fraudsters learn, adapt, share insights, and then repeat the cycle. Always searching for vulnerabilities, they create new and complex methods to circumvent detection. For example, during the pandemic, banks and other on-line business are seeing a significant increase in spear phishing, cross-site scripting, and man in the middle attacks. Tack on impersonation scams, scary intrusions like the SolarWinds hack that has left government and commercial organizations scrambling, and incessant BOT attacks and its clear the velocity and diversity of attacks add a whole new level of complexity…and the dollars start adding up quickly! Not only do these attacks result in higher costs for financial organisations but they create significant brand blow back. Online businesses, especially banks, need to rethink their identity verification protocols landing on those that balance digital identity solutions that factor in identity, context, and behavior. Context is a key element to ensure a balanced approach and mitigate overreactions. Because with fraud currently surging, there is a danger that financial institutions over-correct and prevent customers from completing legitimate transactions. Organisations need to resist the urge to implement stringent measures or checks and instead they need to be smarter in rooting out fraudulent purchases in the first place.
Harmonizing Identity…the only real verification
Effective identity verification starts with harmonizing all of a customer’s disparate digital personas into one digital identity. Every customer has multiple digital personas with which they transact in the online world. For example, assuming email as the common credential denominator (along with an appropriate password), a customer may use Gmail to access Lloyds Bank, Yahoo for a Gumtree ad, and Hotmail to place a Tesco grocery order. While each of these are all different digital personas, they represent the same customer. Understanding the collective personas and associating them with one harmonized identity provides the necessary confidence as to the integrity of the identity. Next, understanding the context derived from prior transaction history, device information, location, and intent data like searches and outcome data, allows organizations to also add a predictive element to the analysis. Together, these factors help build confidence that the customer is legitimate and, equally importantly, whether to trust the customer within the context of the transaction.
The Time Space Continuum
Context can help interpret behavior that would otherwise be immediately flagged for fraud. Consider a customer that has just purchased a jacket at John Lewis using a London IP address and then immediately purchases a package tour from an IP in Reykjavik. Relying solely on the IP signals would flag the second transaction as likely fraud. However, if the person routinely uses a VPN while making transactions and using the Reykjavik IP is a known transactional attribute, then the time distance conundrum is nonexistent because the 1173-mile journey is just a quick digital hop…it’s likely legitimate and hasn’t broken the laws of physics. If it’s also determined that the customer has been searching for Iceland trips and subsequently books a flight, the tour purchase becomes even more credible because every transaction that uses those elements is mapped to that digital identity and strengthens the association between that specific transactional element and the identity’s behavior.
While one imaginary purchase is certainly not the whole picture, financial institutions need to make these decisions around fraud in an instant. Without the proper contextual information, banks and other organisations can easily flag a genuine purchase as fraudulent and is so doing, aggravate the customer and because of transaction abandonment, hand market share to their competitor. The only solution that fits the bill is to harmonize digital identities. Armed with a verified identity, deterministic facts (the customer is in London) and probabilistic measures (the customer is planning on visiting Iceland) the transaction assessment will be accurate and eliminate friction.
Use digital identities that are:
- built on global consortiums that provide a global view of a customer
- harmonized to ensure no single digital persona is compromised or acting anomalously
- provide both deterministic and probabilistic insights
- and most importantly, built on consented and permissioned data
COVID-19 and the subsequent increased use of digital banking products have opened the door to fraud. While fraudsters try to take advantage of the current situation, financial institutions can ruin their schemes by ensuring that they work with the best data partners in order to provide the context needed to verify transactions and reduce friction.
