Cisco Elastic Services Controller REST API Authentication Bypass Vulnerability Threat Alert
maio 17, 2019
Overview
Cisco has released a security advisory, announcing the existence of a REST API authentication bypass vulnerability (CVE-2019-1867) in Cisco Elastic Services Controller (ESC). This vulnerability is due to improper validation of API requests. An attacker could exploit this vulnerability by sending a crafted request to the REST API. A successful exploit could allow an unauthenticated, remote attacker to execute arbitrary actions through the REST API with administrative privileges on an affected system. (mais…)

2018 DDoS Attack Landscape-6
maio 15, 2019
3.4 Behavioral Analysis of Attack Sources
In the 2018 H1 Cybersecurity Insights8, we mentioned that the number of DDoS recidivists (repeat DDoS offenders) was too large to ignore. Of all internet attack types, 25% of attackers were recidivists responsible for 40% of all attack events. As for DDoS attacks, 7% of attackers were recidivists that launched 12% of attack events. (Here, “DDoS recidivists” refer to source IP addresses that have been marked by NSFOCUS Threat Intelligence center (NTI) as DDoS attack sources.) Clearly, in DDoS attacks, the proportion of recidivists decreased in 2018, indicating a lower level of resource reuse. This can be attributed to two factors: (mais…)

A Look into RSA 2019: Interpretation of the Application Security Trend — DevOps and API Security
maio 14, 2019
As cloud computing, big data, Internet of Things (IoT), and mobile Internet evolve, application forms and requirements are going through changes. I believe that the application security trend virtually highlights technologies and design theories: technological innovations continue to focus on API concepts; the design theories of solutions, products, and services continue to move towards DevOps (development and operations). In this article, I will discuss the application security trend. (mais…)
New Words at RSA: Machine Learning Abuse, XAI, Election Security, and CISA
maio 13, 2019
The RSA Conference is the world’s biggest IT security meetings of the highest quality. Initially as a small cryptography forum set up in 1991, this conference has developed into a meeting at which renowned security experts from all around the world are invited to discuss the future cyberspace development and global security vendors are attracted to showcase their information security products.

Using NLP-based Machine Learning to Automate Compliance and Risk Governance
maio 10, 2019
The Governance, Risk & Compliance track of the RSA Conference 2019 focuses on quantification of cybersecurity risks and related cases. For example, Superforecasting II: Risk Assessment Prognostication in the 21st Century by Rich Howard from Palo Alto Networks dwells upon how to evolve semi-quantitative risk assessment into more accurate quantitative risk assessment; Math is Hard: Compliance to Continuous Risk Management presents the entire process of quantitative risk assessment; NIST Cybersecurity Framework and PCI DSS provides practices of implementing PCI-DSS standards in the cybersecurity framework (CSF) and points out complex mapping relationships between the two.

2018 DDoS Attack Landscape-5
maio 8, 2019
3.3 DDoS Attack Duration
3.3.1 Attack Duration Distribution
In 2018, the average duration of a DDoS attack was 42 minutes, down 17% from 2017. This indicates that DDoS attacks were upgraded in industrialization, weaponization, and efficiency and DDoS-as-aService gained momentum for fast growth. We noticed that the longest DDoS attack in 2018 lasted around 12 days, far shorter than attacks detected in previous years. (mais…)
A Look into RSA 2019-Automation of Threat Discovery and Response
maio 7, 2019
The RSA Conference 2019, which is dedicated to addressing worldwide information security issues, was held in March 4–8. This year’s RSA Conference took “Better” as its theme, aimed at exploring new cybersecurity development realms in a digital epoch and finding better security vendors, products, services, and solutions. In the past few years, with the rapid adoption of big data and artificial intelligence (AI) techniques, players across the security industry have been energetic in pushing “better” application of these new techniques in the security field. Detection and response are the two permanent security topics much talked about at both last year’s and this year’s conference. This indicates that security vendors are inputting more resources into AI-automated detection and response. By combining automation, process orchestration, AI, and machine learning, they try to optimize their centralized security management and operations platform for more automatic and intelligent threat discovery and response.
