Hacking the smart city – time to take notice of the warning signs

In Blog post by Clavister Blog Staff0 Comments

The recent demonstrations of how modern cars’ controls can be hacked and tampered with remotely has highlighted the need to build security into the Internet of Things, to stop hackers using the ever-increasing connectivity of important safety-related systems to their advantage.   There was another reminder of the urgency of this earlier this week, when a bored French hacker accessed a sign on a major road in the city of Lille and altered its usual messages to something which took motorists by surprise.   This did not lead to any significant disruption  –  just some amusement, and maybe mild offence to some passers-by.  But it is another clear example of …

Small Devices, Big Security – Protecting the Internet of Things

In Blog post by Clavister Blog Staff0 Comments

Just in case you haven’t encountered the phrase before, the Internet of Things (IoT) is the expanding network of interconnected, internet-enabled devices. To give you an idea of scale, this means that everything from controllers for central heating and household appliances, to vehicles and military equipment, all have the potential to be internet enabled, communicating to a variety of third parties, and to be controlled from a centralised device using the power of the internet.   The IoT offers a range of opportunities, not just for consumers wanting to set their TV to record an episode of their favourite TV show whilst eating out, but also for a range of businesses including …

How SDN and NFV are redefining security

In Blog post by Clavister Blog Staff0 Comments

There are big changes happening in the way large networks are being built, provisioned and managed.  Virtualization is being embraced by telcos, service and hosting providers to deliver maximum computing power at lower cost, by minimising the need for specialised physical appliances.  This allows these organisations to use commercial-off-the-shelf platforms to run their virtualized networks, reducing costs and complexity while also enabling rapid deployment, scalability and easier management to support their future needs.   And as networks change, the way those networks are secured also needs to change.  Clavister is a leader in delivering security to critical, large-scale networks for telcos, ISPs and data centre hosts, and our CTO John Vestberg …

Security: Sometimes More Is Less

In Blog post by Clavister Blog Staff0 Comments

In 2004, the US psychologist Barry Schwartz published a book titled The Paradox of Choice: Why More Is Less.​  The book puts forward the argument that the sheer range of possibilities and options presented to us in our daily lives leads to ‘choice overload,’ and causes people to set unrealistic expectations of the good, services and products they choose.  Those expectations are frequently not met, causing people to question their choices.   It’s the same in IT security.  Security vendors are continually developing new technologies and methods to address the latest emerging threats.  Organisations are investing in those solutions and deploying them – but despite these ongoing investments, breaches and attacks are …

United Airlines and NYSE: cyberattacks or system glitches? Does it matter?

In Blog post by Clavister Blog Staff0 Comments

It’s been another interesting week from a cybersecurity perspective.  On Wednesday 8th July, a report issued by Cambridge University and the Lloyds insurance group suggested that a successful cyberattack on America’s electrical grid could create $1tn dollars of damage. A trillion dollars is such a huge sum that it can’t easily be grasped.  But on the same day, two incidents happened that highlighted the vulnerability of business systems in the event of outages – and the potential scale of the possible losses if a major attack was successful. First, United Airlines grounded all its US flights for two hours, due to ‘network connectivity’ problems.  Flights were restored, but only after …

Clavister shows how to secure large-scale wifi network for smart cities

In Blog post by Clavister Blog Staff0 Comments

Together with partners DataCom and Ruckus Wireless, we recently built a large, secure and reliable WiFi network for the 2015 Royal Swedish Yacht Club ÅF Offshore Race in Stockholm – one of the world’s biggest ocean races, with over 200 boats from across Northern Europe taking on the 350 nautical mile course.  With around 200,000 spectators at the event, the network was designed to handle multiple access points and large numbers of concurrent users, covering the entire island of Skeppsholmen in the centre of Stockholm. By implementing web filtering and managing bandwidth usage, our technology has given spectators and participants with secure, high-performance access to WiFi.  This points the way …
