What is Ransomware? 

Ransomware is a kind of malware that makes users unable to access a computer system or files by locking or encrypting them until a ransom is paid. Normally, cybercriminals spread ransomware through phishing emails, infected websites, or vulnerabilities in software. Once ransomware has been activated, it demands payment, usually in cryptocurrency, for the key to decrypt it or to restore access to the affected system or data. If the ransom is not paid, the files may get lost permanently or be damaged further. 
 
How to Protect Your Organization from Ransomware Attacks: 

Ransomware has grown to become one of the more serious types of attack-from the smallest government entities to huge organizations, often with devastating effects. This kind of malware encrypts a system's files and demands payment for the key to unlock them. Attackers may also threaten to leak, erase, or make data permanently inaccessible. Critical sectors, such as hospitals and emergency services, have much more at stake in case an attack succeeds in compromising life-saving missions and affect public safety. 

Ransomware prevention is a proactive process that involves several layers of defense and collaboration across your whole organization. The following are four key steps to reduce the risk of a ransomware attack and limit damage in case it does happen: 

1. Develop Policies and Procedures 

Establish a full incident response plan that defines how your organization will respond to a ransomware incident. Include in this the roles and responsibilities of the IT, legal, and other teams that will be called upon. Regularly review and update this plan to address infrastructure and personnel changes. Conduct tabletop exercises to identify and fill gaps. 

2. Maintain Regular Backups 

The best recovery from a ransomware attack is having secure, tested backups. Backups should be stored offline or in the cloud, where attackers cannot reach them. Backup files should be periodically tested to ensure their integrity and that they have not been compromised during an attack. 

3. Strengthen Your Network and Assets 

You need to know your network before you can defend against ransomware. Regular inventory of hardware and software is necessary to understand your attack surface. Employ configuration and practice in a way that ensures the elimination of possible vulnerabilities. Pay special attention to network ports, such as RDP and SMB, because they are commonly used by ransomware. 

4. Train Your Team 

Ransomware usually enters an organization through human error, such as opening a malicious attachment in an email. It is of paramount importance to provide extensive security awareness training that will help employees recognize phishing emails and refrain from accidentally triggering an attack. Regular realistic training campaigns will better prepare your team to identify potential threats and take appropriate action. 

Additional Protection Measures 

• Implement Intrusion Detection Systems (IDS): Use an IDS to detect early signs of a ransomware attack by monitoring network traffic for malicious patterns. 

• Endpoint Protection: Enhance your defenses with Next Generation Antivirus (NGAV) and Endpoint Detection and Response (EDR) solutions to monitor and block malicious activity at the device level. 

Best practices, coupled with these steps, will go a long way toward minimizing the chance of a ransomware attack and the resultant damage to an organization. For more in-depth strategies, consult the CIS Controls and other documentation from trusted authorities such as CISA and the FBI.
