Protect corporate networks in times of uncertainty

NSA warns of wave of cyber attacks on Exim servers by Russian group Sandworm - Tenable review Cybersecurity

The start-up Boostrs, specialist in skills mapping and data analysis, estimates that 62% of jobs in France could be practiced in full or partial telework, according to their latest research. While telework, which was put in place as an emergency last March because of the health crisis, has enabled many companies to continue their activities, this format has also helped to review the general functioning of organizations. One of the main consequences is indeed to have demonstrated that certain activities could be performed remotely with the same level of productivity.

For Philippe Alcoy, security specialist at NETSCOUT, containment was an opportunity for organizations to put networks back at the heart of their processes, and to adopt appropriate practices to face the potential risks of attacks and loss of performance.

“For several years, companies have adapted to different degrees and have encouraged teleworking, but few large organizations have dealt with the majority of their employees accessing company resources entirely outside their office – in such a short time . Suddenly, the VPN became the central connection point for the majority of businesses. We have also observed that in France, the use of VPN was 84% ​​higher than in 2019.

However, even if companies have put many measures in place to ensure that the capacity of these networks is sufficient to withstand the growing demand, network visibility professionals are concerned about the risk run by organizations dependent on these networks. networks. For this, IT teams must be certain that the network is available and usable by remote employees.

To help companies to continue their activities using remote networks, our past experiences have allowed us to understand that:

• Denial of service (DDoS) attacks targeting the availability of virtual services, which totaled 8.4 million in 2019, will continue.

• Cybercriminals, whatever their mobile, target services essential to the operation of the business. With telework more widespread in recent months, VPN concentrators may also be at the top of the list of services on which the organization depends.

• Sectors that are already critical, such as public and health organizations, as well as finance, will remain prime targets. Their strategic character in the functioning of a state in times of crisis, makes them all the more attractive for malicious actions.

Faced with ever more sophisticated attacks by cybercriminals, and an unprecedented increase in demand for network capacity, organizations must more than ever prepare for their online services – namely remote access for employees, portals for vendors and partners, online sales, school exams – can be affected by failures or DDoS attacks. To protect themselves against problems with network malfunctions, companies can start by using SaaS services for productive suites, or collaboration tools, in order to reduce, at first, their dependence on VPNs and thus avoid everything. lose if it was attacked. It is also important that employees avoid playing via their work terminals and that this does not go through the corporate VPN so as not to further vulnerability of the corporate networks and increase costs.

The current crisis is causing a lot of concern, and the availability of remote services unfortunately adds to an already long list of challenges posed by this period. Fortunately, there are ways to respond to these challenges. With the massive use of telework and distance education, remote access networks have become a technological pillar, asking businesses and those responsible for their availability to do what is necessary to protect them. “
