And for good reason. Ransomware attacks are the most significant cyber threats facing businesses today.
It only takes one click too many to be caught in the fire of such attacks!
With the increasing number and scale of these attacks, coupled with today's industrialization of cybercrime, and its democratization (RaaS: Ransomware as a Service) companies must urgently:
It is obvious that, whatever the type of threat, a weak plan to counter the potential effects puts an organization much more at risk of being very badly affected.
Businesses must be determined when it comes to protecting themselves against threats. And in this fight, prevention is the best defense. Because when is the best time to stop a fire? As soon as possible of course, but ideally before it even happens.
Therefore, answering the above question entails:
Criminals most often use the following attack vectors:
Many successful attacks demonstrate that the real issue for companies is more their neglect of adversaries' initial access than the ransomware itself.
In relation to our 3 vectors, here are the main measures to be put in place.
Realistically, having these preventative measures in place does not ensure that attackers cannot enter your extended perimeter and gain access to a user's device.
A user receives a malicious email that appears legitimate, prompting them to click a link or download an attachment containing malware.
Once the user clicks on the attachment or the link, the attack is launched.
Without proper endpoint protection, there is nothing organizations can do to detect and stop the attack.
The best solution is a Managed Detection and Response (MDR) service that can detect, quarantine and remove ransomware, preventing loss of data access, and the financial loss or time investment that could result.
Of course, the ability to detect and stop attacks doesn't stop there.
It is therefore essential to have sufficient visibility into anomalies, through the collection, monitoring and cross-correlation of event logs.
For example, in the case of gateway access, this is to collect and monitor logs for unauthorized access attempts.
The MDR service, in addition to detecting, quarantining and removing ransomware, is also able to automatically reverse any changes that could possibly have been performed by malicious code in Windows environments, allowing you to get back very to normal very quickly.
However, your last resort defense should always be based on creating, maintaining and frequently testing your offline, encrypted, and immutable backups, especially for your critical data.
When it comes to ransomware, prevention means denying attackers initial access to any part of your business.
A comprehensive strategy should incorporate the following points:
To effectively fight ransomware, you have 2 alternatives:
In this second scenario, it is important to note that a small investment can make a huge difference.
