Businesses Divided Over Who Poses Greatest Threat To Network Security
Sophos recently published the results of research into the types of user that businesses fear is most likely to expose networks to IT threats. The research shows that 31 percent of companies believe remote or mobile users expose their networks to the greatest threat, compared to 25 percent that consider guests or external contractors the greater danger. In contrast, an additional 44 percent of companies believe ‘standard’ (office-based) employees are actually more likely to expose the network.
According to Sophos, many businesses struggle to ensure that their mobile workforce adhere to the same security policies as their desktop users. This is because they have insufficient insight into whether these remote machines are equipped with the required software, system patches and up-to-date security applications. Furthermore, Sophos experts note that guests and contractors are often overlooked from this equation and allowed to forgo these security checks entirely, greatly increasing the chances of exposing the company network to attack.
Survey results:
Which user exposes your company to the greatest threat?
- Guests: 11 percent.
- Contractors/outsourced labor : 14 percent .
- Remote and mobile employees 31 percent.
- Standard employees: 44 percent.
"Remote workers and guests can be a real headache for IT administrators trying to safeguard corporate networks, particularly when they're using different devices, different security software and different operating systems or system patches," said Graham Cluley, senior technology consultant at Sophos. "These users don't have malicious intentions, but if they're allowed to log-on, they can inadvertently expose the network to a myriad of security threats. Without a solution for standardizing who and what is allowed network access, these companies are greatly increasing the risk of leaving avenues open for cybercriminals to exploit."
The research also highlights the large proportion of organizations that hold concerns over their desktop-based employees -- workers that are likely to be using similar devices and permanently connected to the network. Whether down to irresponsible online behavior, using peer-to-peer applications or instant messaging programs, or simply because their PC isn't correctly configured, any employee that doesn't adhere to internal security policy could be exposing the network to threats.
"It's concerning how many companies are unaware of non-compliant machines being used on their network, even though they may be permanently connected,” Cluley said. "However, irrespective of where the problem lies, the answer is the same. Smart network access control solutions can now help organizations comprehensively enforce their security policies, ensuring that any non-compliant device, whoever it may belong to, is locked down and unable to jeopardize the network."
