- 1) Security experts suggest several precautionary measures for preventing a ransomware attack.
2) Use anti-virus and anti-malware software or other security policies to block known payloads from launching.
3) Mke frequent, comprehensive backups of all important files and isolate them from local and open networks.
4) Immutable backup options such as Object Lock offer users a way to maintain truly air-gapped backups. The data is fixed, unchangeable, and cannot be deleted within the time frame set by the end-user. With immutability set on critical data, you can quickly restore uninfected data from your immutable backups, deploy them, and return to business without interruption.
5) Keep offline backups of data stored in locations inaccessible from any potentially infected computer, such as disconnected external storage drives or the cloud, which prevents them from being accessed by the ransomware.
6) Install the latest security updates issued by software vendors of your OS and applications. Remember to patch early and patch often to close known vulnerabilities in operating systems, browsers, and web plugins.
6) Consider deploying security software to protect endpoints, email servers, and network systems from infection.
7) Exercise cyber hygiene, such as using caution when opening email attachments and links.
8) Segment your networks to keep critical computers isolated and to prevent the spread of malware in case of attack. Turn off unneeded network shares.
9) Turn off admin rights for users who don’t require them. Give users the lowest system permissions they need to do their work.
10) Restrict write permissions on file servers as much as possible.
11) Educate yourself, your employees, and your family in best practices to keep malware out of your systems. Update everyone on the latest email phishing scams and human engineering aimed at turning victims into abettors.
