Latest Ransomware Attack Highlights the Need for Advanced Security Automation and Orchestration Solutions

The latest ransomware attack that broke out last Friday, affecting more than 200,000 computers across 150 countries by Sunday, once again highlighted the need for improved preparedness to respond to large-scale cyber incidents by implementing advanced security automation and orchestration solutions capable of containing the damage from such events. In this case, the attackers exploited a vulnerability in Windows Server Message Block (SMB) protocol, which had been discovered and kept quiet for exclusive use by the National Security Agency (NSA).

WannaCry, as the virus is called, is delivered via an email attachment and when executed, paralyzes computers running vulnerable Windows operating systems by encrypting their files. Once it encrypts a computer’s hard disk, WannaCry then spreads to vulnerable computers connected to the same network, and also beyond, via the Internet. This is in many ways a typical ransomware attack, infecting computers with a virus that has the ability to spread quickly to other vulnerable systems; however, the infection in this instance, and the speed at which it spread, was more intense than any other such attack in recent memory. The consensus among cyber security experts around the world is that the damage from this attack could have been reduced to a minimum, and more serious consequences could have been avoided, if organizations had been better prepared and had more effective cyber incident response plans and solutions in place.

Early Detection and Damage Containment via Security Orchestration, Automation and Response (SOAR)

When affected by an attack such as WannaCry, after an organization’s computer system has been breached, the best thing that the organization can do is try to keep the incident under control by preventing the infection from spreading. There are various security solutions designed to achieve this end, but a SOAR platform is arguably the best suited for the task. When an infected computer is detected, this platform can quickly isolate it in the early stages of an attack, blocking traffic to and from it to contain its spread, and thus reduce the business impact to a minimum.

Recovery and Remediation

Once containment is achieved, the platform provides organizations with the ability to quickly remediate the incident by guiding cybersecurity professionals through the entire process, using pre-defined Incident Response playbook actions for a faster and more effective execution. The playbook actions can suggest the best remediation and recovery methods, and how to enforce them in the most effective manner. For instance, how to restore files and update the appropriate firewall rules.

All of the above is only a fraction of the capabilities of a typical automation and orchestration platform, a security tool that has become critical for any organization seeking to avoid the immense cost and long-lasting consequences of cyber-attacks such as WannaCry.

Cyber-attacks such as this one are only expected to become more common and more sophisticated in the future, and for this reason WannaCry should serve as an example of why now is the time for organizations serious about cyber security to focus on improving preparedness and containment capabilities through investment in advanced security automation and orchestration.
