Robust administrative security required to prevent Wi-Fi viruses

BitDefender UK : 03 March, 2014  (New Product)
Bitdefender comments on the creation of the wi-fi virus and how passwords are no longer enough to provide the necessary network security levels
Robust administrative security required to prevent Wi-Fi viruses

Following the news that researchers in Liverpool have created Chameleon, a computer virus that can spread via wi-fi, Catalin Cosoi, Chief Security Strategist at Bitdefender, explores why network security should be reliant on more than just passwords:

Chameleon’s potential to spread through networks “like a common cold” highlights the importance of having robust administrative security procedures in place; an area that is overlooked by many.

Passwords are simply not a foolproof method of avoiding infection. There are many well-known issues with static passwords, which ultimately boil down to one thing: passwords are a single point of potentially catastrophic failure if used by themselves in authentication scenarios. Passwords can be forgotten, lost, stolen or intercepted in transit, and because they need to be kept in one’s head and human memories are limited, they can be guessed with alarmingly good results.

Organisations should take steps to ensure that critical infrastructure and routers are protected from this, and similar, virus threats and technology should be the element that makes the difference. So called "home" routers and networks are actually way beyond most people's IT administration skills, and as such the need to secure them doesn't even register. The complexity of these systems also means that there is often need for outside help from an IT professional – and the most likely candidate to offer this will in all likelihood usually be first-level support for an internet service provider (ISP).

In order to achieve true protection, security and maintenance should be simplified and automated as much as humanly possible. Things should just work (securely) out of the box, because most people don't have the time, inclination or indeed motivation to become network security professionals.

Catalin Cosoi’s work sets the agenda for the development of new security threat countermeasures. Over the last 7 years, Catalin has acquired a thorough understanding of key areas of technology and is able to offer expert comment on security topics relating to mobile threats, outbreak detection, proactive phishing detection and cloud computing.
