DNS (Domain Name System)
DNS stands for "Domain Name System." It is a hierarchical and decentralized naming system used in computer networks and the internet to translate human-readable domain names, like "www.example.com," into the IP addresses computers use to identify each other on a network. In essence, DNS acts as a directory that enables users to enter short, easy-to-remember domain names to access websites and other internet resources. In contrast, computers and servers communicate using IP addresses.
DNS operates by maintaining a distributed database that contains various types of records associated with domain names. Some common DNS record types include:
A Record: Associates a domain name with an IPv4 address.
AAAA Record: Associates a domain name with an IPv6 address.
CNAME Record: Creates an alias for a domain name, redirecting it to another domain.
MX Record: Identifies the mail servers in charge of a domain's email message receiving.
TXT Record: Stores human-readable text that can be used for various purposes, such as domain verification or authentication.
NS Record: Lists the authoritative name servers for a domain.
A web browser contacts a DNS server when you enter a URL (Uniform Resource Locator) to convert a domain name to an IP address.
It entails a series of queries that lead the way to the authoritative DNS server for the given domain, starting with the root DNS servers. The browser can connect to the proper server hosting the webpage once the IP address has been established.
DNS plays a crucial role in making the internet accessible and user-friendly, as it allows people to use easily recognizable names rather than having to remember complex numerical IP addresses for every website they want to visit.
ThreatNG is an External Attack Surface Management (EASM), Digital Risk Protection (DRP), and Security Ratings Solution with Domain Intelligence that can significantly benefit an organization and its entire digital ecosystem regarding DNS security and overall cyber risk management. Here's how each component contributes:
External Attack Surface Management (EASM): EASM involves identifying an organization's digital footprint and the points of exposure to potential cyber threats outside its internal network. It includes discovering all the domains, subdomains, IP addresses, and other online assets associated with the organization. In the context of DNS, EASM can help by:
Identifying Unintended or Unauthorized Domains: EASM tools can find domains registered using the organization's name or variations, helping prevent brand impersonation or phishing attacks.
Detecting Misconfigured DNS Records: EASM can uncover incorrect or improperly configured DNS records that could lead to security vulnerabilities or service disruptions.
Monitoring for Changes: EASM continuously monitors changes to DNS records, alerting the organization to unauthorized alterations, such as DNS hijacking attempts.
Digital Risk Protection (DRP): DRP identifies and mitigates risks across an organization's digital channels, including the web, social media, mobile apps, and more. Concerning DNS, DRP can provide:
Domain Monitoring: DRP can watch for domains similar to the organization's legitimate parts but might be used maliciously. It helps in detecting phishing campaigns or brand abuse.
DNS Data Leak Prevention:** DRP can identify instances where sensitive DNS data is exposed or leaked, helping to prevent potential data breaches or insider threats.
Threat Intelligence Integration: DRP solutions can integrate threat intelligence feeds that provide insights into known malicious domains, allowing the organization to block access to or communication with these domains.
Security Ratings with Domain Intelligence: Security ratings assess an organization's security posture and provide insights into its cyber risk. Domain Intelligence within such solutions can:
Assess DNS Security: Domain Intelligence can evaluate an organization's DNS configuration and security practices, highlighting areas of improvement.
Evaluate Third-Party Risk: Security ratings, including partners and vendors, can extend to the organization's digital ecosystem. It can analyze the DNS security of these external entities to ensure they meet security standards.
Provide Context for Risk Assessment: By incorporating DNS-related data into security ratings, organizations can better understand how their DNS posture contributes to their overall cyber risk profile.
Integrating External Attack Surface Management, Digital Risk Protection, and Security Ratings with Domain Intelligence can help organizations enhance their DNS security, reduce the risk of cyber threats, and maintain a more secure and resilient digital presence. This comprehensive approach assists in identifying vulnerabilities, preventing attacks, and responding effectively to emerging threats in the ever-evolving digital landscape.
