A Federal Times article recently noted that three former Federal IT Executives, including two high ranking IT security officials from the Office of Management and Budget (OMB), felt that government IT security was too focused on compliance and “oftentimes do not reflect their agencies’ most critical security needs”. In a new report entitled “Measuring What Matters: Reducing Risk by Rethinking How We Evaluate Cybersecurity”, the authors note that government agencies “continue to spend scarce resources on measures that do little to address the most significant cyber threats.”
The report outlines the authors proposal for a new approach to security, the Organization Cyber Risk Management Framework. This is a risk-centric security management posture that focuses on establishing a security baseline for agencies that allows them to correctly asses their risk posture based on empirical data. The authors note that in order to move to this framework, agencies must first implement automated continuous monitoring programs, which they identify as “continuous diagnostics and mitigation, configuration management, threat assessment, and remediation practices.” We at FireMon could not be more excited to see the report identify the importance of configuration management, and we have highlighted the importance of configuration management as it relates to risk on this blog previously. When discussing a risk-based approach, security practitioners tend to gravitate to threat management. Threat management is sexy; it includes attacks and attackers, and makes security practitioners feel more like MacGyver vs. Dilbert. Configuration Management on the surface seems less sexy. Getting notification that someone added a new ACL to a router doesn’t invoke images of thwarting a hackers attack. Consider the all to common scenario though where the router admin fat-fingered said ACL, and accidentally enabled access to an internal network that should not have access from the outside world. Without real-time configuration change alerting that can identify a violation of agency or corporate security policy, an attacker might end up being the one that ultimately alerts the organization to the misconfiguration.
The report is very comprehensive, and provides a very through framework for how to implement a risk based security practice. While it is clearly focused on Federal Government agency environments, it provides some good insights for corporate security practitioners as well. The report concludes that “To fix the problems of today and those of the years ahead, government should implement a more consistent method of evaluating cybersecurity threats — one which is measurable, transparent, and outcome-oriented.” It is refreshing to not only see a recommendation on moving to a risk-based security posture, but one that includes the importance of device configuration management and its importance in truly knowing your risk posture.
Yet another systems breach was reported last week, this time at the University of North Florida affecting 23,000+ students. This in and of itself is unfortunately nothing new, as we have been inundated weekly with reports of breeches occurring at organizations throughout the last 18 months. What struck a chord however with this incident at UNF is that it is not the first time that the college had experienced data loss from an external attacker. In October of 2010, the school was also attacked by an external hacker, and 107,000 students were affected in that incident. UNF has posted an FAQ on the latest attack here. One of the more interesting questions is what is the university doing to make sure this doesn’t happen again, with the school providing the following answer: “The method used by the intruder to gain access has been identified and steps have already been taken to prevent a reoccurrence. The University Police Department, in conjunction with Housing and ITS, is investigating this incident.”
Considering this is the second time the school has been attacked, one can imagine this response wasn’t too reassuring to the students. The incident also shows that the traditional reactive approach to security needs to be replaced by a proactive, risk-based approach. After the first incident in 2010, the school stated that “The university shut down the compromised server and has taken other precautions to prevent future incidents.” One can only assume that the specific exploit on the specific server that was compromised was patched against, or maybe a specific service blocked on the firewall. Reacting to that specific threat and assuming that the remediation actions taken protected the school moving forward clearly was not the most comprehensive approach to protect against future threats.
The most successful organizations that combat risk today “have a much better handle controlling what is deployed on their networks and whether these assets are vulnerable to imminent threats” as Jon Oltsik noted earlier this month on his blog. He also pointed out though that only 20% of organizations today have a risk management plan in place that includes some form of threat intelligence. FireMon has always believed it is important to proactively identify areas of Risk, whether they come from adding a rule to your firewall that inadvertently introduces risk by being overly permissive, or by identifying in real-time what assets on your network are most vulnerable to exploitation. With the release of Security Manager 6.0 with Risk Analyzer add-on, organizations now have a complete Security Posture Management tool that provides unparalleled visibility to understand the scope of business vulnerability and prioritize the proactive defense of critical assets, while maintaining a high confidence that their security infrastructure is free of human error or incompatibilities between policies and protection. Avoid having to post a breach FAQ; adopt a proactive risk based approach to security management today.
The amount of news generated around attacks in 2011 has been overwhelming. In just the last week, the reports around SCADA based attacks have reached almost histrionic levels. Attacks on NASA, AT&T & VCU have all been highlighted this month as well. Despite the fact that companies will spend over $8 billion dollars on network security this year, hackers continue to successfully breach networks with an alarming regularity.
In an article on APT’s posted on Dark Reading yesterday, Sean Brady from RSA had an interesting quote. He said “Identifying the entry point — where an attacker got into a company’s network — is a key aspect of identifying and responding to an advanced attack”. At Firemon, we couldn’t agree more. However, we would also ask why wait until you’ve been attacked to discover the entry point? Why not proactively find the entry point yourself? As clearly indicated by the attack coverage we’ve seen in the press this year, the attackers are actively looking to find the entry point into your network even as you read this post.
Firemon’s new Risk Analyzer technology is designed to proactively find the entry point into your network that can be exploited. Risk Analyzer will also identify where an attacker can pivot off that access point, and what other resources within your network can be compromised. Risk Analyzer will also prioritize what patched vulnerabilities can reduce the greatest amount of risk with the least amount of effort, helping to focus your organization’s remediation efforts. Don’t be the last to discover the entry points that are exposed in your network; he who finds the entry point first wins.
