Ransomware is generally delivered to the victim’s system through phishing, making an unsuspecting user click on a malicious link. Once ransomware is installed on the device, it starts encrypting files and sends an extortion note to the victim.
What makes ransomware even more worrisome is that in many cases, attackers don’t unlock the data even when the ransom is paid. Businesses of all sizes are increasingly targeted by ransomware attacks, including small to medium-sized enterprises (SMEs).
To make sure your system doesn’t get infected with ransomware, follow these simple tips.
1. TAKE REGULAR BACKUPS
Ransomware works by encrypting and blocking your access to important data. If you have a current backup of all important data, there is less reason to worry. If you are ever hit by a ransomware attack, you can revert to a previous unencrypted version to regain access to your systems and data.
Your backups should be stored offline and at a location where they cannot be targeted by attackers. Test your backups regularly for efficiency. If you do face an attack, make sure the backup isn’t infected before you roll back. Having a backup is probably the most important line of defense against ransomware.
2. USE A RANSOMWARE PROTECTION SOLUTION
Use a ransomware threat protection software solution that is designed to detect and block threats. For instance, Digital Guardian’s ransomware protection solution filters out noise and provides deep visibility into advanced threats.
3. BEWARE OF PHISHING ATTEMPTS
Ransomware is most commonly spread through phishing. Make sure you or your team doesn’t click on untrusted links. Most phishing attempts are done through emails so it’s important to avoid suspicious emails.
Phishing awareness training should be given not just to the IT security team but to all employees of the organization.
4. SANDBOXING
Sandboxing all communication, especially emails, can add protection to the system. Since human errors cannot be completely avoided, having a secure email gateway solution can be helpful in keeping your system ransomware-free.
There must be email filters in place that filter out emails that might contain suspicious links or unknown file types.
