IPv6: A Tale of Two Protocols – by the VIMRO Team
Posted in Cyber Security, tagged Cyber Security, Cybersecurity on June 21, 2015|
Where are the IPv6 vulnerabilities?
What you need to do.
Currently your IPv6 traffic is “tunneled” across an existing IPv4 network because we live in an IPv4-dominated world. This tunneling creates an entry point for many vulnerabilities yet to be discovered, although quite a few have already been discovered. The majority of our network traffic monitoring tools are also based on IPv4 computer networking. Focusing on IPv4 protocols without an equal emphasis on IPv6 traffic puts us at risk in this mixed-IPv6 world. We may only be seeing part of the picture.
The truly disquieting aspect of IPv6 is that it is constantly looking for configuration information from network routers. This information is easily falsified and may be used to auto-configure IPv6 stacks. There are also many opportunities to “fuzz” the IPv6 protocol to find weaknesses specific to stack implementation. While IPv6 is not currently accessible outside of the local network, this means that the local network may be vulnerable to attack from within, while IPv4 monitoring tools sit idly by.
Further, stack-level compromises do not require services to be enabled on a target machine, exposing a vulnerability at a level below web, ftp, and other network services. Therefore, a machine with no network services whatsoever may become a victim of an IPv6-based attack. So for those networks that don’t need IPv6 – disable it! For those that do, consider securing your IPv6 implementation:
- Make sure that IPv6 routing information is authoritative for your IPv6 domain
- Make sure that IPv6 naming services are authoritative for your IPv6 domain
- Ensure that IPv6 parameters applicable to your stack are configured and not open to auto-configuration
- Ensure that firewalls that support IPv6 are configured properly
- Keep in mind that IPv6 traffic is often tunneled over IPv4
While most security companies tend to focus only on the IPv4 network, essentially missing some vulnerabilities that experienced attackers may use to compromise your network, VIMRO actively examines IPv6 as a component in our network assessments.

The PCI DSS Reaper – Are you ready for what’s coming?
Posted in Cyber Security, tagged Compliance, Cyber Security, Cybersecurity, PCI DSS, Uncategorized on March 30, 2015|
Any reference to cybersecurity in the Payment Card Industry (PCI) context strikes fear into the hearts of professionals across the globe. Its nebulous requirements and their extensive drain on both IT and business efforts can eat up resources faster than an F22 fighter jet gulping down jet fuel. Worse yet are the constantly changing standards! The latest incarnation of the Data Security Standard (PCI DSS 3.0) contains new language that leaves a considerable gap in understanding the changes to the requirements imposed on organizations.

VIMRO – Advanced Vulnerability Assessment and Penetration Testing
Posted in Cyber Security, tagged Cyber Security, Enterprise Tech Infrastructure on January 26, 2015|
How do you truly know that your critical data and infrastructure are secure? VIMRO can answer this question with our Security Testing and Assessment (ST&A) services. According to NIST SP 800-115 – Technical Guide for Security Testing and Assessment, an information security assessment is the process of determining how effectively an entity being assessed (e.g., host, system, network, procedure, person, etc—known as the assessment object) meets specific security objectives.
VIMRO uses three types of assessment methods to accomplish this: testing, examination, and interviewing.
- Testing is the process of exercising one or more assessment objects under specified conditions. This is used to compare actual and expected behaviors.
- Examination is the process of checking, inspecting, reviewing, observing, studying, or analyzing one or more assessment objects to facilitate understanding, to achieve clarification, or to obtain evidence.
- Interviewing is the process of conducting discussions with individuals or groups within an organization to facilitate understanding, achieve clarification, or identify the location of evidence. Assessment results are used to determine security control effectiveness over time.
- VIMRO has extensive experience in ST&A for both commercial and government enterprise and clouds-based ecosystems.
