One of the most important issues around cybersecurity is ransomware attacks. This is because of the disruptive and damaging effect on sensitive operations that these targeted events may have. The significance of personally identifiable information (PII) and research-based intellectual property that organizations acquire and store is understood by attackers.
Small or big, no business is immune to ransomware. However, it is possible to prevent the major harm and cost of a ransomware attack when companies can identify and fix the initial compromise quickly. When it comes to defending against ransomware, the following serves as a simple and practical guide for organizations.
Endpoint, Email and Network Protection
Ninety percent of ransomware cases include an accidental insider who clicks a link, according to available data. This can be avoided with suitable email protection solutions that are also complemented with a capability of endpoint detection response to capture anything that might not have been prevented by the email security solution. Of the remaining 10 percent of ransomware cases, most were the product of an unpatched public-facing server that had minimal detection and was exploited. A network security appliance combined with daily patching has proven excellent for prevention in these situations.
Multi-Factor Authentication Is A Must
The use of a single factor to access sensitive infrastructure is observed, which allows actors to use compromised credentials to gain access quickly. Especially as the remote workforce grows, it is vital to use powerful multi-factor authentication tools that include something you know (e.g., username and password) with something you have (e.g., token) and/or something you are (e.g., biometrics).
Granular Visibility is Crucial
Most companies today have diverse networks that include a mixed infrastructure with on-premises and cloud services. With integrated threat intelligence and continuous monitoring of devices and links, security teams need granular visibility through these environments. The visibility into the real-time detection of when a user accesses backups is a key for ransomware.
Segment Critical Data
Threat research suggests that to grasp environments, hackers conduct considerable reconnaissance. In order to counter this, ensure that a strategy is in place to secure the “crown jewels,” the most valuable data that, during a ransomware incident, may be leaked to the public. This strategy includes establishing the principle of least privilege in account provisioning, maintaining distinctions between the functions of administrator and regular user account access, and distinguishing between administrators and controllers between login permissions.
Have An Incident Response Plan
This is a mature, practiced strategy that plans for incident response for all teams-IT, marketing, legal, human resources, etc. When a ransomware attack happens, the aim is to prevent hurried decisions. To that end, guide teams to slow down and ask questions like:
Do we know the vector of infection and whether an attacker is active?
Have the attackers got the real data?
Will the attack have the ability to escalate?
How soon will we recover? Do we have the offline backup? Is there any control over who accesses backups?
Ransomware is going to keep getting more advanced. Given the important data they carry, government agencies, healthcare organizations, and educational institutions are at increased risk for such accidents.
There is no one-and-done approach. Instead, there are different factors and questions to consider. Start by asking: Is my organization safe? It’s time to make some fine adjustments if you do not have a binary answer to that. Also, enterprises should invest in data security solutions that offer comprehensive data security with their best-in-class security features.
