The Domain Name System (DNS) is the cornerstone of communication for the internet. Navigating to the sites you access every day often starts with a DNS request. Cybercriminals recognize the value of DNS and may look for ways to abuse improperly secured DNS to compromise its uptime, integrity or overall response efficacy—which makes DNS an important area for enforcing security and protecting against threats.
The Domain Name System (DNS), if not properly secured, may be susceptible to abuse by malicious actors. Cybercriminals recognize the value of DNS availability and look for ways to compromise DNS uptime and the DNS servers that support it. As such, DNS becomes an important point of security enforcement and a potential point in the Cyber Kill Chain®1 for many cyber-attacks.
This blog discusses one such threat, DNS reflection and amplification attacks.
To establish connectivity with other users and devices, almost anything that interfaces with the internet depends on the accuracy, integrity and availability of the Domain Name System (DNS). Most online transactions and data movement are critically dependent on DNS services.
As such, DNS is an important point of security enforcement and a potential point in the Cyber Kill Chain for many cyber-attacks. Organizations are beginning to recognize this and are using DNS security mechanisms as a first line of defense for preventing or mitigating online threats.
Verisign is excited to announce that its easy-to-configure, cloud-based, recursive DNS filtering service, Verisign DNS Firewall, is now certified to run on Microsoft Azure. This service will help protect your Microsoft Azure virtual machines from malware command-and-control traffic and navigation to undesirable websites.
Verisign is pleased to announce that we qualified for the Online Trust Alliance’s (OTA) 2017 Honor Roll for showing a commitment to best practices in security, privacy and consumer protection. This is the fifth consecutive year that Verisign has received this honor.
The OTA is an initiative within the Internet Society (ISOC) with the mission to promote best practices for online trust. Now in its ninth year, the 2017 OTA audit analyzed nearly 1,000 websites across multiple industry segments, evaluating the websites for consumer protection, security and privacy protection practices, and has been embraced by organizations worldwide as an objective benchmark report.
Verisign just released its Q1 2017 DDoS Trends Report, which represents a unique view into the attack trends unfolding online, through observations and insights derived from distributed denial of service (DDoS) attack mitigations enacted on behalf of Verisign DDoS Protection Services.
Launching a DDoS attack is much more accessible to attackers thanks to the rise of cloud computing, cheap hosting, readily available bandwidth and open-source attack tools. From low-skilled teenagers aiming to cheat while playing online games to cybercriminals looking to supplement their income by renting out their botnets for opportunistic attacks, the DDoS-for-hire market is booming.
