Verisign is deeply committed to protecting our critical internet infrastructure from potential cybersecurity threats, and to keeping up to date on the changing cyber landscape.(more…)
Recent events1,2 have shown the threat of domain hijacking is very real; however, it is also largely
preventable. As Verisign previously noted3,
there are many security controls that registrants can utilize to help
strengthen their security posture. Verisign would like to reiterate this advice
within the context of the recent domain hijacking reports.
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.
One such threat: cache poisoning. (more…)
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.
A comprehensive defense-in-depth strategy requires security mechanisms to be applied through the implementation of hardware, software and security policies. Hardware protection includes, but is not limited to, the implementation of next generation firewalls (NGFW), intrusion prevention systems/intrusion detection systems (IPS/IDS) and secure Web gateways (SWG). Software-based protection is done through anti-virus software deployments, automated patch management or tools for Internet monitoring. Finally, no defense-in-depth strategy would be complete without the implementation of strong security policies that prescribe processes for incident reporting, service and system audits, and security awareness training.
Cybersecurity is no longer a concern for just IT and security professionals. Recent breaches at organizations like Sony, Target, JP Morgan Chase, and numerous U.S. government entities have brought the issue of cyber-attacks very close to home. If you bank online, use your debit card at a local store or engage in any activity that relies on an Internet-connected system, you are at risk.
Today’s new age of ubiquitous connectivity has created an insatiable and growing demand among employees and consumers to be online with familiar systems and tools at all times. Employees are no longer satisfied with the limited choices in devices and tools provided to them by their corporate IT organizations. They want to use what they want,when they want. They believe that choosing their own devices and tools provides them with the highest level of comfort and efficiency. This desire to use personal devices in work environments, referred to as “bring your own device (BYOD),” coupled with the growing cyber-attack surface, poses significant challenges to IT organizations. These challenges are leading such organizations to ask themselves – Are we ready to support BYOD?
Defending against cyber threats is not only critical, but increasingly difficult and expensive. Just a quick glance at today’s news headlines and it is clear that these threats present numerous challenges to Internet users and the organizations that both serve and employ them. For example, in 2014, McAfee Labs observed a 75 percent year-over-year increase in new malware equating to 387 new threats per minute. Further, the Ponemon Institute estimates the average data breach costs large organizations $3.8 million per event.
Most solutions either require extensive investment or do not meet an organization’s constantly evolving needs. Traditional, appliance-based security solutions can require organizations to shell out considerable amounts of money, both in up-front capital expenditure and in on-going maintenance fees. Conversely, many managed cloud-based offerings do not provide the critical capability to customize the solution based on an organization’s specific business environment and security needs. Finally, do-it-yourself (DIY) open-source solutions suffer from constant patching and maintenance problems.
Enter the Verisign DNS Firewall, an easy-to-configure, cost effective managed cloud-based service that offers robust protection from unwanted content, malware and advanced persistent threats (APTs), delivered with the ability to customize filtering to suit an organization’s unique needs.
