Wi-Fi is everywhere, everything is on Wi-Fi now, phones, tablets, laptops, even home PCs, game consoles, smart devices (IoT), sensors etc. The security of WiFI is imperative, and has been entrusted to the WPA2 protocol. For that protocol, thus far all exploits have been connected to guessing the security key (hence reliant on customers having […]

As you probably know the Equifax (one of the three big credit bureaus in North America and UK) announced it was breached (discovered unauthorized access) on the 29th of July. So far, the predictions are that this leak of sensitive personal data impacts over 143 Million American, Canadian and British citizens. What is a credit […]
A new malware Nyetya (combination of words from Nye Petya, meaning NOT Petya), also known as Petrwrap and GoldenEye has been spreading globally over the last 24 hours. This virus is distinct from WannaCry and other initially suspected variants, it has some unique new features which makes it harder to detect and defend against, clearly […]
Cisco currently has multiple endpoint security solutions in place – CWS (Cloud Web Security / Scansafe), Umbrella (OpenDNS) and AMP for endpoints are prime examples. AMP is a different breed of endpoint protection, it relies heavily on detection based on heuristics and cloud sandboxing, where as CWS and OpenDNS both concentrate very strongly on making […]
As you might be aware this Friday (12th of May 2017) there was a massive outbreak of a new type of crypto virus dubbed WannaCrypto aka WannaCry. The UK was hit the hardest, especially in the Health Sector, with Spanish Telecom – Telefonica, along with Portuguese & Argentinian telecoms and Russia. How does that affect […]
Virtual Private Networks constitute a hot topic in networking because they provide low cost and secure communications between sites (site-to-site VPNs) whilst improving productivity by extending corporate networks to remote users (remote access VPNs). Naturally the VPN technology is widely deployed on all internet edge devices and most ASAs. Cisco is very proud of its VPN solutions. It’s one […]
Cisco has finally decided to merge its two major network security products – the ASA and FirePOWER. These two have been living on the same hardware (5500X) model for years now but they required separate management which increased the deployment and operational costs for a Cisco FirePOWER implementation. Now Cisco has decided to merge these […]
The breakthrough SHA-1 is dead, from a security point of view, but has been a long time coming. A combined research collaboration between CWI and Google, published a paper on 23th of February 2017 that proved deliberate collisions can be created for SHA-1 (Secure Hash Algorithm -1). The researchers managed to forge a PDF doc […]
We are experiencing a new phase in our vision of network security. There is currently no quick fix solution, no 100% proof network security protection/prevention tool or product. There is always zero-day or purposely built (very focused, low spread) APT malware that current vendors are unable to detect at the time of the breach. Hence […]
There is not a single industry anywhere in the world who are immune from the threat of some form of cyber-attack. Any attacks on your organization’s IT Network will be unpredictable in terms of the exact method of attack, but you can at least be poised to deflect and protect your company from such cyber-attacks […]
