@RISK provides a reliable weekly summary of (1) newly discovered attack vectors, (2) vulnerabilities with active new exploits, (3) insightful explanations of how recent attacks worked, and other valuable data
A key purpose of the @RISK is to provide the data that will ensure that the 20 Critical Controls (the US and UK benchmark for effective protection of networked systems) continue to be the most effective defenses for all known attack vectors. But since it is also valuable for security practitioners, SANS is making it available to the 145,000 security practitioners who have completed SANS security training and others at their organizations who hope to stay current with the offensive methods in use.

============================================================NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP
Title: Apple Releases Critical Security Updates for Mac OS X, iOS, watchOS, and Other Applications Description: Apple has released seven security bulletins to address a variety of vulnerabilities that have been identified in various software platforms such as Mac OS X, iOS, watchOS, iTunes, and Safari. Several vulnerabilities in OS X, iOS and watchOS are deemed critical as they are remotely code execution flaws which could be exploited through a maliciously crafted image file sent via MMS. Many other critical and important vulnerabilities were also addressed in these bulletins. Users are advised to install these security updates as soon as possible. Reference: https://support.apple.com/en-us/HT201222 Snort SID: Detection pending release of vulnerability information
Title: ISC Releases Security Advisory for a Denial of Service Vulnerability in BIND Description: ISC has released a security advisory for CVE-2016-2775, a remotely exploitable vulnerability that could result in a denial of service for systems. The vulnerability manifests if lwresd is configured to accept remote client connections and a query where the query name exceeds the maximum allowable length. ISC has released an updated version of BIND to correct this issue. Reference: https://kb.isc.org/article/AA-01393 Snort SID: Detection pending release of vulnerability information
Title: Cisco, Juniper Release Security Advisories for Various Products Description: Cisco Systems and Juniper Networks have released security advisories for flaws that have been identified in IOS XR and Junos respectively. Flaws specific to IOS XR are CVE-2016-1426, which could lead to a denial of service condition due to the system leaking timer resources. Flaws affecting Junos include CVE-2016-1279, a information disclosure flaw; CVE-2016-1278, a credential bypass flaw that could allow an attacker to login as root without a password; and CVE-2016-1276, a denial of service flaw. Both Cisco and Juniper have released updated software correcting these issues.
