Security response headers are a critical security capability that all organizations should consider. This blog post is the first in a series that will discuss different security headers and go in-depth with how to configure them for maximum benefit. For cyber criminals, attacking a web application directly is not the only option available. They also have the ability target other users of the system in order to steal their information,
By Tim April -------- Update (Sept. 17, 2018): On Sunday, September 16th, the ICANN Board adopted a resolution instructing the ICANN Organization to continue the Root KSK Roll as planned, switching the Root KSK at 1600 UTC on October 11, 2018. --------- On October 11, 2018 -- for the first time ever -- the Root Key Signing Key (Root KSK), that is the single root of trust used to verify
Ryan Barnett, Principal Security Researcher, Akamai Moshe Zioni, Director of Threat Research, Akamai Recent news reports have highlighted the latest evolution of the Mirai botnet code, which is itself an evolution of the Kaiten botnet. The botnet developers have leveraged features from an open-source project, called Aboriginal Linux, that results in a cross platform compiled binary. Needless to say, this greatly increases the success rates of spreading the Mirai malware
Ryan Barnett, Principal Security Researcher, Akamai Elad Shuster, Senior Security Researcher, Akamai In this blog post, we will discuss different Denial of Service (DoS) attacks that may negatively impact your API services, as well as mitigations offered by Kona Site Defender (KSD).
This blog post is a follow-up to https://blogs.akamai.com/2018/08/apache-struts-vulnerability-cve-2018-11776.html and its purpose is to highlight attack data we have seen on the Akamai network related to this vulnerability.
Our exploration of methods for normalizing the number of web application attacks sourced by each country has only considered contextual variables from external sources that characterized each country in a context devoid from Akamai, so far. This final leg of the journey will situate the attack counts within a context that is specific to Akamai and the characteristics of the attacks themselves.
On the week of July 15th, researcher Juha-Matti Tilli disclosed a vulnerability in the Linux kernel to the kernel maintainers, the National Cyber Security Center - Finland (NCSC-FI), CERT Coordination Center (CERT/CC), and Akamai. The vulnerability, CVE-2018-5391, is a resource exhaustion attack triggered by a specially crafted stream of IP datagrams that cause expensive processing within the Linux kernel. This vulnerability is similar to the Linux TCP vulnerability announced August,
In the last installment, we introduced the challenge of normalizing a geographic visualization showing the observed number of web application attacks sourced from each country. This time, we'll try to discern which potential normalizing variables could have a significant relationship with the attack counts through exploratory analysis and hopefully gain some new insights.
On the week of July 15th researcher Juha-Matti Tilli disclosed a vulnerability he discovered in the Linux kernel to the kernel maintainers, the National Cyber Security Center - Finland (NCSC-FI), CERT Coordination Center (CERT/CC), and Akamai. The vulnerability, CVE-2018-5390, is a resource exhaustion attack triggered by a specially crafted stream of TCP segments which creates expensive processing within the Linux kernel. In preparation for the public disclosure of the vulnerability,
