Ransomware Security Threat – What Is It And How To Prevent It?
The hype about malware attacks isn’t without a reason. Malware types are the most dreaded hacking means that affect businesses of all sizes, no matter what industry you represent.
Ransomware, a kind of malware, is shaking the infrastructure of many companies and is spreading with the speed of wildfire. When a system gets infected with ransomware, the attackers lock you out of your own system and denies access to the data. Then comes the demand for a ransom in lieu of decrypting the hacked information. The threat is serious because the security information of thousands of customers is at risk. Thus, you should be very mindful of;
- Not opening links from unreliable sources. The links might have a malware that’ll launch an attack as soon as you’ll click it open.
- Educating your employees about the importance of not entertaining personal emails from the company’s system.
Clearly, ransomware primarily feeds on the lack of awareness. The best ways to prevent your company against such threats are listed below.
- Use Firebreaks
Fire breaking (network segmentation) is a fantastic method to limit the damage caused by malware. It involves dividing the data into multiple parts and storing different pieces of information in different independent networks. When there are multiple networks in 1 company, vulnerability in the systems in any 1 network will not affect all the networks at once. It will buy precious extra time for your cybersecurity team to inform all employees to disengage from their systems so that the hackers cannot crawl their way in other networks. As a result, the damage will be substantially very less.
- Use Elemental Security Layers
The 3 elemental security layers that all devices require are – a strong backdoor password, a firewall, and an anti-virus.
- A strong backdoor password will deny forced entry to hackers. Using multi-factor authentication as a password is also a useful tip.
- A firewall guards the information even if the backdoor password is compromised.
- An antivirus keeps all the systems free from viruses from internal links via emails/malicious websites and external devices like pen drives and hard disks.
- Router Management
Did you know that hackers can easily exploit the wifi router to spread malware in all the networks at once? Under this circumstance, fire breaking (network segmentation) will be of no use. Thus;
- Keep your wifi password protected and limited only to the employees.
- Reboot the router from time to time since rebooting discards any existing hidden malware immediately.
