Traditional Security is not DNS Security. Today’s news regularly highlights stories about the often disastrous impacts of cyberattacks and the resulting compromised business impacts. Frequently, the companies attacked have sophisticated security systems in place, but even the best traditional security is not DNS security. Layered security, next-generation firewalls, and secure web gateways were not designed to protect DNS and DNS protocol can be easy to exploit. The growth in the number and type of new devices connecting to the network has exposed holes in typical enterprise security. Traditional security solutions tend to focus on particular devices or protocols and cannot provide a broad-based solution that covers all devices and applications.
The DNS server is one of the primary and most vulnerable infrastructure components through which companies suffer Denial of Service and Distributed Denial of Service (DoS/DDoS) attacks. Companies are at constant risk of service interruptions due to failure of DNS servers that become overwhelmed by malicious queries and their assorted malware-generated cousins. The current threat landscape is continuing to grow rapidly as these attacks impact budgets, reputations, consumers and clients. DNS has now become the number two attack vector only being preceded by HTTP.
PCN can expertly assess, design, manage and mitigate the risks in protecting your mission-critical DNS services from attack. Benefits of PCN insuring DNS Security is specifically targeted and addressed within your business can include:
- DNS is the starting point for connectivity and is used by all devices to connect to applications and sites – leveraging the pervasiveness of DNS as that starting point can prevent malicious activities before they can reach business-critical applications or data to secure your business.
- DNS Protection provides a centralized view of attacks that have happened on your network. These views help you identify attack patterns early and isolate issues so that you can start taking corrective action and mitigate future attacks.
- DNS can provide an added security layer for all devices. This includes both traditional and non-traditional such as Smart phones (corporate-owned or BYOD), desktops and laptops, point-of-sale (POS) systems, Unified Communications and Collaboration systems, security cameras and “everything IP”. All rely on DNS to connect to the network and external sites and can be protected from accessing malicious content and serving as a threat vector for security intrusions.
