Enterprise security professionals have their hands full these days—monitoring networks for security breaches, managing the implications of “bring your own device” policies, and patching systems to combat “weak links,” or vulnerabilities that could allow online criminals to grant entry.
Regarding this last task, security practitioners may be able to take an approach to addressing vulnerabilities that allows them to more effectively allocate resources toward resolving these challenges. As detailed in the Cisco 2014 Midyear Security Report, urgent critical vulnerabilities—those that merit the time and attention of security executives—make up a very small number of reported vulnerabilities. While all reported vulnerabilities should be patched, it’s wise to focus on those that pose the most danger.
Cisco publishes thousands of multivendor alerts every year, and zero-day vulnerabilities (for which patches are not yet available) tend to win the lion’s share of attention from security practitioners and the media because of their perceived urgency. However, only about two percent of the thousands of reported vulnerabilities were being activity exploited soon after published reports.
Today, we released the first Cisco IOS Software Security Advisory Bundled Publication of 2014. Six years ago, Cisco committed to disclosing IOS vulnerabilities on a predictable schedule (on the fourth Wednesday of March and September each calendar year) in direct response to your feedback. We know this timeline allows your organization to plan ahead and ensure resources are available to analyze, test, and remediate vulnerabilities in your environments.
Today’s edition of the Cisco IOS Software Security Advisory Bundled Publication includes six advisories that affect the following technologies:
Most recently ESG/Vormetric came out with a threat report that highlighted the increase in insider threats & the significance to augment perimeter and host-based security. The rationale behind the increase was that more people are accessing the network, increase cloud and network traffic are making it difficult to isolate the problem.
Almost 50% of the organizations believe they are vulnerable to insider attacks and have or plan to invest dollars.
This is alarming!
The top methods noted for these insider threat vulnerabilities were abuse of access by privileged users, contractors, and other employees. Security professionals are finding it quite difficult to monitor the users, traffic, ports, etc to identify and mitigate insider threats. They must glean this information from multiple sources and many times need to translate the data. For example, “whose IP address is this and why is Mary from finance, who is supposed to be on vacation, downloading data from the payroll server?” This process slows the resolution time. The criticality of this type of contextual information is enormous to remediate quickly.
Security needs to be pervasive and consistent to manage these inside threats—so how does one do this? Integrate security into your infrastructure (wireless, wired, VPN)! Once security is woven into your infrastructure it provides the visibility and clarity to respond in a timely manner with a high degree of efficacy and is not dependent on distinct and isolated ingress points.
That’s right folks, today is Patch Tuesday and Microsoft has published its monthly security bulletin for August 2013. The bulletins address a total of 23 vulnerabilities in Microsoft Windows, Microsoft Internet Explorer, and Microsoft Exchange. These vulnerabilities could allow an attacker to execute arbitrary code, cause a denial of service condition, or gain elevated privileges.
The bulk of the August updates correct several vulnerabilities in Internet Explorer. Although little technical information is available currently, it’s likely that attackers may develop future exploits based on the vulnerabilities.
Multiple vulnerabilities correct vulnerabilities in Microsoft Windows. A few of the vulnerabilities involve improper processing of ICMP network packets and could allow for attacks that cause affected systems to stop responding to additional network traffic. Although service failures are a concern for production systems, an exploit would allow no system access. Read More »
