The growing attack surface challenge in the realm of cybersecurity involves the identification, classification, and securing of all network-accessible assets to minimize exploitable entry points, or the Attack Surface, and reduce the risk of breaches. With the proliferation of IoT devices and BYOD policies in workplaces, the attack surface expands as each new device becomes a potential entry point for cybercriminals. Managed Service Providers (MSPs) face a daunting task in managing this diverse and dynamic attack surface for multiple clients. One major challenge is the lack of visibility into clients’ network resources, leading to gaps in security and making both MSPs and their customers vulnerable to breaches. MSPs cannot afford to ignore Attack Surface Management (ASM) as it is crucial for maintaining compliance with industry regulations, documenting asset risks, and demonstrating due diligence during investigations. Prioritizing ASM not only helps shield against cyber threats but also creates a safety net in case of a security incident, making it an essential aspect of MSPs’ cybersecurity strategies.
Strategy for Managing the Attack Surface
To manage their attack surface and that of their customers, MSPs would greatly benefit from a robust strategy that includes:
- Asset identification: Understand what’s on the network. This involves identifying and cataloging network-connected devices, including IoT and personal devices under a BYOD policy.
- Risk evaluation: Once assets are identified, you need to assess the associated risks, prioritizing assets based on their vulnerability to threats and potential impact on the network.
- Vulnerability control: You then need to take action to secure these assets. This could involve anything from patching outdated software and tightening network access controls to establishing stringent security policies for IoT and BYOD devices.
- Ongoing monitoring: This allows for timely identification of new assets and vulnerabilities, facilitating swift action and threat response.
How to Apply Best Practices with N-able
With N-able EDR, MSP’s can utilize features, such as Advanced Surface Management, to minimize the attack surface by:
- Quickly identifying unknown and IoT devices
- Isolating suspicious devices from others on the network
- Installing EDR on eligible devices that are not yet protected
- Allowing MSPs to pinpoint anomalies that could signal potential threats
