Jaga seda postitust

The emergence of COVID-19 pandemic has pushed remote work to a new normal. According to Forbes, tens of millions of employees use their own mobile devices to work remotely from home. This offers an opportunity for cybercriminals to attack those unprotected mobile devices and endanger the network security of enterprises.

This is the reason why it is crucial for enterprises to adopt a reliable network security services. Cybersecurity professionals indicated that 2020 will be a critical year for managed security services as it is getting more and more popular around the world, and may become one of the important components of security services.

The Importance of OT Security

Gartner defines Operational Technology (OT) security as, “Practices and technologies used to protect people, assets, and information, monitor and/or control physical devices, processes and events, and initiate state changes to enterprise OT systems.” Align with the technology development, the demand for OT security solutions has grown exponentially.

OT security service is the full stack of hardware and software being used to monitor, detect and control changes to devices, processes and events. It can protect processes, people and profit and significantly reduce security vulnerabilities and incidents. The main driver of adopting OT security is discovering, profiling, tracking and managing assets to detect cyber and operational anomalies. As vendors enhanced their OT security capabilities, enterprises are starting to blend passive and active security technologies to effectively manage their assets.

How Managed Security Service can Help?

Managed security service includes the processes of “prevention”, “detection” and “correction”. “Prevention” is  to maintain the customers’ infrastructure in an ideal state by monitoring any violation of security policies and alerting them when a known vulnerability affects them. “Detection” is to identify and respond to security incidents in real time. And “Correction” is to identify, analyze and remedy undesired modifications to systems, devices and applications.

Through managed security services, enterprises can identify and prevent unauthorized changes and real threats timely, limit the actions of hackers in the corporate network environment and perform quick remediation, thereby greatly reducing the time to analyze and correlate security logs.
