The security perimeter in organisations is dissolving

18 May 15

As users reconnect their devices, Monday mornings see a massive increase in malware detection, according to research published in the annual NTT 2015 Global Threat Intelligence Report.

The findings show that the security perimeter in organisations is dissolving, due to end users increasingly using their own devices both inside and outside of the corporate security perimeter.

The report claims IT and security management can no longer count on well-defined network security perimeters to protect their organisations.

The Global Threat Intelligence Report contains analysis of over six billion security events worldwide gathered during 2014 by NTT Group companies including Dimension Data, Solutionary, NTT Com Security, NTT R&D, and NTT Innovation Institute (NTTi3).

Matthew Gyde, Dimension Data’s group executive - Security, says threats targeting end users are higher than ever. In addition, security vulnerabilities are mostly related to end-user systems and not servers.

“It appears that successful exploits occur over the weekend when end users - and their devices - are outside the security controls of the corporate network,” Gyde says. “This indicates that traditional security controls are effective at protecting the corporate network, however assets that transition between corporate and external access points are at greater risk.”

Gyde says controls that address this trend must focus on the user and their devices, regardless of location, and points out that seven of the top 10 vulnerabilities identified were on end-user systems. End users become a liability and that’s because their devices often have many unpatched vulnerabilities.

According to Gyde, the malware industry is maturing, with malware becoming commoditised and available through dark net marketplaces. This means the barrier to entry for cybercriminals is a minimal financial investment, but for a potentially large return.

“And this trend is not about to disappear,” he states. “As users become more accustomed to always-on, real-time access to corporate data, they also become the targets of criminals wanting those same data sources. 

“In summary, users and their devices become the criminal’s entry point.”

Other highlights of the Global Threat Intelligence Report include:

·         Finance continues to represent the number one targeted sector with 18% of all detected attacks.

·         Across the world, 56% of attacks against the NTT global client base originated from IP addresses within the United States. This does not necessarily mean that the attackers reside in the US.

·         76% of identified vulnerabilities throughout all systems in the enterprise were more than two years old, and almost 9% of them were over 10 years old.

·         Of the vulnerabilities discovered across enterprises worldwide, 7 of the top 10 exposed vulnerabilities resided within user systems and not on servers.

·         Threats against the end user are higher than ever, attacks show a clear and continuing shift towards success in compromising the end point.

·         Attacks against Business & Professional Services increased from 9% to 15%.
