By Ronald Sens, EMEA Director for A10 Networks DDoS is a constantly evolving threat. We are seeing DDoS attacks getting more sophisticated, more frequent and bigger than ever before. The systems that are most common in enterprises today cannot keep up with the constantly evolving DDoS threats because many use old technology. It is therefore important that enterprises adopt a modern defence solution that can help meet these newer requirements. Specifically, there are four different...

By Lior Samuelson, CEO, Cyren  The cloud can stop phishing in its tracks faster than appliances After the rise of ransomware over the last few years (largely combatted through better detection of the malware and more attention paid to having decent backups), phishing has stormed back onto the IT security manager’s radar. According to our latest survey on IT security in the UK and Ireland, phishing is now the second most pressing cybersecurity issue after...

“A fool pulls the leaves. A brute chops the trunk. A sage digs the roots.” – Pierce Brown   The western world is currently grappling with a cyber insurgency.  The widespread adoption of the “kill-chain” coupled with the use of memory resident malware has fueled the cyber-attack wild fire.  The security architectures mandated by regulators and standard bodies are collapsing. History does repeat itself. One should study the evolution of insurgencies to better grasp the nature of...

If we asked any of the IT departments that we deal on a daily basis about their current priorities, they would all unfailingly say that protecting their company against cyber attacks and data breaches is top of the list - particularly now that GDPR is finally in force.   However, despite high awareness of the risks in terms of reputational damage, regulatory penalties and commercial losses, it’s evident that a surprisingly high proportion of companies...

By Ronald Sens, EMEA director at A10 Networks In the evolving landscape of mobile networks, we are beginning to see new vulnerabilities open up through 3G and 4G networks, and it is more than likely that 5G will follow this same fate. Protecting only this Gi Interface is no longer enough for service provider security. Until recently, the Gi-LAN connecting the EPC (Evolved Packet Core) to the internet was considered to be the most vulnerable...

For banks, direct debit (ACH) fraud represents a bigger financial risk than card fraud. In particular, growing momentum for real-time payment schemes across the world is creating huge opportunities for fraudsters and placing increasing pressure on banks and clearing houses, who now have only seconds instead of days to identify fraudulent transactions. There are various security approaches available to banks in the fight against fraud, but tokenization has already proved successful in protecting in-store and...

By Anthony Perridge, VP International, ThreatQuotient “Without change, something sleeps inside us, and seldom awakens. The sleeper must awaken.” This quote from Dune is a favourite of mine because it speaks to a phenomenon we see around cyberattacks, particularly those targeting critical infrastructure. In many instances, the industrial control systems (ICS) and supervisory control and data acquisition (SCADA) systems that run such infrastructure have been in place for years. Hesitant to make changes for fear of...

Greig Schofield, Technical Director at Netmetix, explores the murky world of ransomware attacks and shows how organisations can protect themselves against this growing problem. Call me a romantic but I’ve never believed that the stereotypical tall, dark stranger was limited to the world of fairytale.  For businesses in the digital age, a modern-day version is both an everyday reality and a recurring nightmare. Ransomware attacks – perpetrated by faceless, shadowy strangers – are no longer...
