Hello Everyone, Welcome back to Hack Bytes.
Now-a-days Ransomware attacks are one of the most common and dangerous cyber attacks, in which many well known companies had also became a victim.
So let’s take a look on how you can secure any company from Ransomware Attacks:-
Ransomware is a type of a malware, which is referred as a Malicious Software. In ransomware attack the attacker executes a malicious file in your system or network and encrypts all the data of an entire company. And if you want your data back in unencrypted form then they ask for money mostly in the form of Bitcoin, which is also known as “Ransom”. Once the malicious files executes in your system, with a minute it spreads to overall network and encrypts all the data in your entire network. Thus it is one of the most dangerous attack. But we can prevent this type of attacks by taking or implementing some preventive actions like :-
Firewall: Implement an appropriate Firewall in your company’s network. Firewall protects your company’s network from external or internal Cyber Attacks. You can also apply some security filters in website or application to prevent the users from accessing unnecessary sites or applications.
Endpoint Protection Systems: Implementing Endpoint Protection Systems is one of the most important preventive measures to prevent the company from Ransomware or other Malwares. Endpoint Protection Systems protects all the endpoints in your organization from malicious things.
Encryption: Configure a strong encryption system for your data for both, data in transit and data at rest. A strong encryption in your data can save your data to leak or theft.
Backup and BCP-DRP: Regularly taking backup of all your important data is one of the most important practice one can implement in the company. Take a proper backup regularly and store that data in encrypted form outside your company’s network. So in case if company’s network got compromise than one can use that data after sanitizing the network as a Business Continuity Plan (BCP) or Disaster Recovery Plan (DRP).
Patch Management: Implement a proper patch management system in the company to keep each and every network devices or endpoints updated regularly. Keeping all the endpoints updated mitigates all the high or critical vulnerabilities related to version or firmware.
Access Controls: Each and every employee should have access to the required assets only, as per the roles and responsibilities in the company. Implementing least privilege access principle is the most important precautions to have in any company.
Monitoring: Regular monitoring of the Network and System Logs should be in place. One can also implement SIEM Tool to collect all the logs in one platform and also monitor real time logs to prevent the live attacks. Take immediate required actions if you observe any critical logs while monitoring.
Email Protection: Configure e-mail system to block all the malicious, spam or phishing emails properly before entering in your network.
Vulnerability Assessment: Perform regular Vulnerability Assessment and Penetration Testing (VAPT) to identify the existing loopholes in your company’s network or endpoints. Immediately take the necessary actions to mitigate all the vulnerabilities before any attacker exploits that vulnerabilities.
Cyber Security Awareness: Provide a proper Cyber Security Awareness training to all the employees of the company. Provide a proper training to identify phishing emails, malicious links, not executing any unnecessary files…etc.
So these are some preventive steps one can implement in any company against any Ransomware or Malware attacks.
