Ransomware is malicious software which once installed seeks to encrypt all user files and only allow access once a ransom payment is made. Since high profile attacks in 2015 infections against large businesses, government and healthcare providers new variants are targetting smaller businesses and home users.
Ransomware is unique among cybercrime because in order for the attack to be successful, it requires the victim to become a willing accomplice after the fact James Scott
In this article we look at the top 5 ways to stop ransomware gaining hold in your company:
- Regular patching of vulnerable operating system and application software is necessary to help prevent infection. Always ensure your software and operating systems have the latest patches as soon as they are available.
- Most ransomware attacks are triggered through infected email attachments - so take care when receiving any form of attachment - even from a known email address.
- Install Anti-malware and anti-virus software and have a strong business grade firewall to protect your network combined with network security software which automatically monitors network traffic for suspicious behaviour, external server access and threats.
- Have an effective backup policy with onsite and offsite backups - going back over several days, weeks and months.
- Train all of your staff to look for signs of infection and have a tested policy in place in case disaster does strike.
But remember, if for any reason a ransomware attack does get through your defenses and your data is encrypted never pay the ransom, there is a high chance this will not unlock your files and will fund future attacks. A better alternative is to contact a data recovery specialist if you cannot restore your files from a backup.
