Managed Security Services Protect Against Ransomware
Defending against ransomware requires an all-hands-on-deck approach. Whether it’s the costly, disruptive and potentially devastating effect on productivity or the potential loss of client trust, organizations face a raft of risks from this malware threat that demands payment in exchange for decryption keys. Fortunately, managed security services can help protect against ransomware attacks.
A managed security service provider (MSSP) is a cybersecurity solution that offers prevention through continuous monitoring, detection through real-time threat intelligence and behavior analysis, and response through timely incident response and remediation capabilities. These services are essential for defending against ransomware attacks.
MSSPs offer a variety of managed services, including antivirus software and protection, multi-factor authentication, firewalls and VPN services. In addition, they can deploy a number of advanced technologies that include: Threat hunting: Continuously searching for unusual activity that could indicate a cyberattack, such as a rapid increase in file encryption. Threat hunters use behavior analytics and anomaly detection to look for signs of ransomware that can be missed by traditional security measures.
Ransomware is a form of malicious software that infects an organization’s computers or network. The attack may be limited to a single computer or spread to multiple devices in an organization’s network. Once the ransomware has gained a foothold in a system, it can be difficult to stop it from encrypting data. This is why preventing an attack in the first place is so important. In addition to regular system updates, patch management and vulnerability assessments, ransomware defenses can include:
Behavioral Analysis: Examining applications and networks for suspicious patterns that may be indicative of ransomware. This can include determining whether applications are being used outside of normal business practices, or identifying whether an employee is clicking on phishing links or using insecure email programs.
How Managed Security Services Protect Against Ransomware
Endpoint Detection: Using a combination of machine learning algorithms and behavior analysis, the ability to detect and identify new or emerging threats is improved. This can help identify new ransomware variants, as well as detect lateral movement and other indicators of an active threat.
Preventive Measures: Implementing a robust backup and disaster recovery strategy, ensuring data is stored offsite and in the cloud and utilizing strong multi-factor authentication to protect against unauthorized logins. Implementing a robust security awareness training program to educate employees on phishing, suspicious attachments and best practices for keeping data secure.
Isolating compromised systems: Immediately isolating an infected machine can prevent a ransomware attack from spreading. This may require disconnecting from the internet, turning off Wi-Fi or even shutting down a machine.
Documenting the incident: Keeping all evidence of a ransomware infection, such as emails or system logs, can help with reporting and recovery. It is also essential to maintain a relationship with a trusted managed security service provider that can respond to any incidents quickly and efficiently.
Despite the best efforts of organizations to prevent and mitigate ransomware, this malware threat can still have devastating effects. An experienced managed security service provider can help protect against ransomware attacks by implementing an all-of-the-above set of tools and deploying advanced threat detection and response mechanisms.
