There is a “massive increase” in malware detections on Monday mornings when users reconnect their devices to the corporate network, according to new research published in the annual NTT 2015 Global Threat Intelligence Report.
This trend supports the contention that the security perimeter in organisations is dissolving as end users increasingly use their devices both inside and outside the corporate security perimeter.
In fact, according to Dimension Data, the user is today’s new organisation perimeter.
What’s more, 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 with security vulnerabilities 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,” he 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.
Consequently, end users become a liability and that’s because their devices often have many un-patched 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 adds. “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.”
Further findings from the Global Threat Intelligence Report show that finance continues to represent the number one targeted sector with 18 percent of all detected attacks.
Across the world, 56 percent of attacks against the NTT global client base originated from IP addresses within the United States but this does not necessarily mean that the attackers reside in the US.
Meanwhile, 76 percent of identified vulnerabilities throughout all systems in the enterprise were more than two years old, and almost 9 percent of them were over 10 years old and of the vulnerabilities discovered across enterprises worldwide, seven of the top 10 exposed vulnerabilities resided within user systems and not on servers.
Furthermore, threats against the end user are higher than ever, attacks show a clear and continuing shift towards success in compromising the end point while attacks against Business & Professional Services increased from 9 percent to 15 percent.
