Many organizations have been hit with a ransomware attack, and many of them wonder: How did this happen? What they could have done to stop this?
For many organizations and businesses, the answer isn’t clear. That happens, because businesses have many holes in their multiple areas of security practices that pave way for cyberattacks. While most of them aware of this situation, have security software already implemented. So here are the 6 things you should do to stop ransomware.
Application whitelisting is a proactive security approach that creates an index of trusted, approved applications and files that are allowed to run on your system – and prohibits everything else. It’s a contrast to application blacklisting in which only specified threats are prevented and everything on the blacklist is allowed to run.
By its nature, application whitelisting is more restrictive than blacklisting and takes more effort to maintain. Many businesses choose not to whitelist their applications because of its effects on software usability and the complexity of putting it in place.
2.Control User Access
Allowing your employees unrestricted access to your network is a huge security risk. Careless or disgruntled employees can introduce ransomware or other malicious programs that wreak havoc on your system. In addition to giving training to your employees about security keep them restricted to only those files and programs that are needed for their job.
Another smart way to control user access is to restrict the number of users that have administrative permissions. Always try to keep the local and domain administrators restricted to a small number of approved users.
3. Use Smart Password Practices
We can’t ignore this – but smart password practices are one of the easiest ways to protect your system. Although it’s tempting to create easy-to-remember passwords to save yourself from the login headaches it’s never worth the risk.
Use strong passwords that are hard to guess, combine a variety of numbers and characters, and are unique to each account. Also, enable the dual-factor authentication everywhere you want. This will make it harder for hackers to access your system accounts and deploy ransomware.
4.Apply Patches and Update Regularly
Like updates, software “patches” changes a program to connect it from new vulnerabilities that have occurred since its installation. If you are running antivirus or security software that isn’t running with the latest patches and updates, that means you are leaving holes within your security for making it vulnerable to the ransomware attacks. Always run updates and patch as soon as possible.
5.Fire up the Firewalls
Most businesses have the perimeter firewalls in place at the boundary of their network to prevent outside traffic from entering the system. Be sure your perimeter firewall is able to do its job by shutting down connections such as remote desktop systems.
While perimeter firewalls are important, they don’t protect your network from attacks that originate within your system. Many ransomware attacks originate from the inside of your network from push installations or employee activity. You should also run a personal or host firewall to protect your network from inside traffic risks.
6.Protect your File Shares
Since ransomware uses encryption to target your files and hold them ransom, keeping your files is a must even if you have strong security measures in your place. One common area that businesses overlook is the act of file sharing. When you share your file with other users, whether over devices or through the web you can run the risk of being intercepted by hackers.
