What is DNS Security?
In terms of DNS security, there are two parts:
Keeping your DNS services’ integrity and availability high (translating hostnames into IP addresses) DNS activity monitoring to detect if there is a security risk on your network.
What Makes DNS a Target for Attacks?
Before DNS’s creation, no one had ever considered implementing security best practices. DNS doesn’t require any authentication or encryption to work, and it will answer any query that comes its way.
With it as a starting point, there are many ways to deceive customers about where name resolution is taking place.
DNS Security Issues and Components to Be Aware Of
Several broad DNS Security components must be addressed to ensure DNS security as a whole.
- Control and System Harden the servers and provide a default template for the commissioning process for new ones.
- Implement DNSSEC, DoT, or DoH for protocol enhancements.
- To help with security investigations, integrate DNS event recording into a SIEM solution
- Subscribe to a threat intelligence feed that delivers actionable metrics for security and threat intelligence
- Take advantage of the time set aside for security by automating everything you can.
- In terms of DNS security, the above-mentioned high-level components represent the very beginning of the process. More particular use cases and recommended practices will be discussed in greater detail in the next section.
The revolution in remote working
Teleworking has become possible due to technological advancements across several industries. Still, most businesses, even technology giants, do not have the digital infrastructure to make it possible on a broad scale. Even though most organizations have rules, technology, and processes to allow workers to work remotely, only around 15% of employees are anticipated to connect remotely at once, according to earlier estimates.
A safe and sound option
Externalizing this service has been crucial (and very cost-effective) for businesses that lack the equipment, time, and liquid cash to extend VPN connectivity on-demand. SASE platforms enable a crucial part of this approach.
For remote workers, this is a set of services provided by internet service providers and telecommunications companies that enables the use of NaaS (Network as a Service), which connects them to the corporate network via VPN, Firewalls as a Service, DNS, and Secure Web Gateways to minimize security flaws (NSaaS). There has been an enormous increase in the number of cyberattacks in recent years, as evidenced by cybersecurity statistics.
Secure and high-performance DNS services are an essential part of the SASE offering. They guard against DNS assaults and keep company activities running smoothly even when most employees access the network remotely. Edge GSLB (global server load balancing) should be used with DNS to distribute network traffic load among servers.
DDI (DNS-DHCP-IPAM) is critical for a telco’s SASE infrastructure’s service deployment automation because it provides the scalability and speed necessary to meet market demand.
Together, these steps will keep corporate networks functioning well in the new distant work environment that will emerge in 2020 and beyond, despite increased network complexity.
