Vulnerability risk management has re-introduced itself as a top challenge – and priority – for even the most savvy IT organizations. Despite the best detection technologies, organizations continue to get compromised on a daily basis. Vulnerability scanning provides visibility into potential land mines across the network, but often just results in data tracked in spreadsheets and independent remediation teams scrambling in different directions.
The recent Verizon Data Breach report showed that 99.9% of vulnerabilities exploited in attacks were compromised more than a year after being published. This clearly demonstrates the need to change from a “find” to “fix” mentality. Here are three key challenges to getting there:
* Vulnerability prioritization. Today, many organizations prioritize based on CVSS score and perform some level of asset importance classification within the process. However, this is still generating too much data for remediation teams to take targeted and informed action. In a larger organization, this process can result in tens of thousands – or even millions – of critical vulnerabilities detected. So the bigger question is – which vulnerabilities are actually critical?
Additional context is necessary to get a true picture of actual risk across the IT environment. Organizations might consider additional factors in threat prioritization, such as the exploitability or value of an asset, the correlation between the vulnerability and the availability of public exploits, attacks and malware actively targeting the detected vulnerability, or the popularity of a vulnerability in social media conversations.
* Remediation process. The second and perhaps most profound challenge is in the remediation process itself. On average, organizations take 103 days to remediate a security vulnerability. In a landscape of zero-day exploits and the speed and agility at which malware developers operate, the window of opportunity is wide open for attackers.
The remediation challenge is most often rooted in the process itself. While there is no technology that can easily and economically solve the problem, there are ways to enable better management through automation that can improve the process and influence user behavior. In some cases, there are simple adjustments that can result in a huge impact. For example, a CISO at a large enterprise company recently stated that something as easy as being able to establish deadlines and automated reminder notifications when a deadline was approaching could vastly improve the communication process between Security and DevOps/SysAdmin teams.
In other words, synchronizing communication between internal teams through workflow automation can help accelerate the remediation process. From simple ticket and task management to notifications and patch deployment, the ability to track the remediation process within a single unified view can eliminate the need to navigate and update multiple systems and potentially result in significant time savings.
