“When they launch ransomware attacks, we assume that it is already their last resort because the victim has the option to pay or not to pay.”
CF Fong – CEO of LGMS
Attackers do not only target big organizations as they are leaning towards the retail and education sectors trend. According to “The State of Ransomware 2021 Report”, 33% of organizations with between 100 and 1,000 employees were targeted with ransomware attacks last year.
Protecting oneself against ransomware attacks may seem impossible, considering the ever-growing ransomware variants and tactics used by hackers. However, there are still several measures that organizations can take to significantly reduce the level of risk.
1. Setting up layers of virtualization.
Virtualization is the process of creating a simulated computer environment, separated from the physical environment. Practice network segmentation/ virtual networks with adequate access control to prevent ransomware attacks.
2. Keeping software updated and patched.
Software updates ensure your system recognizes newer threats. The past incident shows that companies that neglect to update the system are particularly vulnerable to ransomware attacks.
3. Backup data regularly.
Be prepared to make sure a backup is ready in case of a Ransomware attack on your system. Restore data from a backup to recover from ransomware
4. Early detection helps prevention.
Monitor network administrators if any suspicious network traffic is reported. Conduct a Compromise Assessment at least once a year to spot a hacker’s footprint and repair the loopholes before attacker action.
5. Isolate and restrict access to backup servers from the rest of the shared servers.
Prevent unrestricted access to the backup server from other LAN segments. Several preceding ransomware cases suggest targeting the backup server is one goal to prevent the victim from restoring backed-up data.
6.Establish network trend baselines.
Innovative teams engage analytic technologies to establish baseline network activity norms so anomalous actions can be easily spotted.
