Risk prevention is the best first step. It is much easier to prevent a problem than to try and fix it later.
Prevention
The process of prevention begins with understanding the scope of the network, the capabilities of the users, and the controls and logging in place to protect sensitive data.
CyanLine advises that network security be assessed from an external and an internal point-of-view. While external assessments are very important, internal assessments are also very important to ensure that internal users with some access to the network do not exceed that access.
CyanLine knows that you can't just allow anyone to assess your network security. You need to be able to trust your network security partner, and CyanLine has earned the trust of banks, government agencies and technology companies to help ensure the appropriate controls are in place.
To assist in preventing unauthorized access or disclosure of information, we provide the following services to find security issues before they are exploited:
-
Network Security Audits
-
Penetration Testing
-
Vulnerability Assessments
-
Application testing
Research
When possible, our first step is to interview the end-users, as they often knew what works and what doesn't with respect to security. We also look to the existing policy to see how effective and enforceable is realy is. We weigh how the policy impact business goals and workflows. A policy that interrupts business processes is likely to be circumvented, ultimately weakening network security.
One example of the research performed by CyanLine is the examination of Internet Network Connectivity. This research looked at the growth of the Internet through the relatively passive means of examining BGP tables.
Tools
CyanLine uses a wide variety of proprietary and open source tools, such as:
-
AP-Finder for wireless assessments
-
nmap for open port assessment
-
nikto for web assessment
-
tcpdump for traffic analysis
-
and more...

Why won’t my call go through? Denial of service in the cell phone network.Mon, 30 Jan 2012 19:50:02 +0000 - Recently, some of the major cellular carriers have released “Network Extenders”, also known as femtocell. The network extender is a device that a subscriber purchases to extend the reach of the cell phone network. (In effect, the subscriber is paying for the privilege of increasing the cellular network coverage. What a deal!) The network extender [...] SCADA and securityWed, 30 Nov 2011 13:49:10 +0000 - A recent article by Hal Hodson of Information Age reports that the FBI has publicly stated that hackers have successfully targeted SCADA systems in three unnamed US communities. The attacks were reported to have the potential to shut down electricity at a nearby mall as well as the potential to dump sewage. Just weeks earlier came an announcement from the [...] How to find hidden passwords (and how to protect them)Fri, 30 Sep 2011 15:27:46 +0000 - While preparing to teach a computer forensic workshop, I discovered a new live Linux distribution entitled C.A.IN.E, (Computer Aided Investigative Environment.) This software is one of a few live Linux distributions that allows a user to boot Linux from a CD or DVD and start a forensic investigation. The distribution includes tools to make forensic [...] Revenge HackingMon, 01 Aug 2011 03:26:15 +0000 - Revenge is a powerful motivator for hacking. Take, for example, the case of Barry Ardolf of Minnesota. Trouble started when Mr. Ardolf was accused by a neighbor of kissing their 4-year boy on the lips. When the parents confronted Mr. Ardolf, he confessed that the accusation was true. Naturally, the parents of the 4-year old contacted the police. This made Mr. Ardolf angry [...] Are Macs immune to virus or malware?Tue, 31 May 2011 21:15:35 +0000 - A couple of weeks ago, I was asked to check on a Windows-based computer that had recently been infected with a “virus scanner” malware. In this case, the malware (malicious software) would put up a pop up screen that was kind enough to inform you that your computer was loaded with a bunch of virus infections. Further, it [...] |
