Layered defense: not a luxury, but a necessity

According to Allianz Global Corporate & Specialty, the damage caused to the global economy by online crime in 2016 (including direct losses, lost profits and system restoration costs) exceeded $575 billion. This is about 1% of global GDP.

I am sure that the results of 2017 will not be encouraging. The last two major waves (WannaCry and Petya ransomware attacks) have once again confirmed that even large corporate networks cannot withstand virus attacks and other information threats. The situation is even worse for small and medium businesses, government and educational institutions - often their protection system is represented only by antivirus software on workstations. This, of course, is not enough to protect against a variety of modern information security threats: where an antivirus will repel an attack by a ransomware, another can "slip through" through vulnerabilities in unupdated software.

A reasonable response to the growing threat level is to russia whatsapp data protection at the network level. Network perimeter protection and local network segmentation (division into several subnets with mandatory filtering of inter-segment traffic) provides protection against virus penetration into the protected circuit or allows preventing complete infection of the network and critical blocks (computers of the financial department, accounting, database servers, backups, production process control systems).

Most modern threats penetrate the network via the Internet - this is confirmed by the analysis of the methods of distribution of WannaCry and Petya. Servers on Windows OS, directly connected to the Internet, transfer the "infection" to the entire local network of the company, while exploits can block the operation of the pre-installed firewall or specialized software, including antiviruses, even when certain ports are closed. This is why comprehensive solutions for protecting corporate networks based on Windows are a patient who is more alive than dead.
