Internal continuous monitoring is a strategy whereby businesses may more quickly and easily identify IT compliance issues and security risks within their organisation.
This differs from vendor-risk continuous monitoring which focuses on ongoing monitoring of third parties and suppliers.
For most modern organisations, the IT ecosystem is anything but static. Today's IT environments are always growing and changing, constantly increasing in complexity and capability. Unfortunately, as advancing IT systems continue to push the frontier in terms of business functionality, they are also pushing back against IT departments' capacity to mitigate evolving security threats. With new promises comes new risk, as well as new regulatory measures with which IT organisations must remain compliant. For many businesses, continuous monitoring is the solution.
As one of the essential parts of a risk management framework (RMF), internal continuous monitoring empowers organisations by allowing them to constantly review their IT security posture. Internal continuous monitoring helps determine whether the required, deployed and planned security controls continue to be effective when faced with inevitable changes to company information systems. When correctly applied, this approach is effective for securing new—as well as inherited—security controls and assessing the potential impact of planned and unplanned changes to the IT hardware, software and environment.
Modern businesses rely heavily on their various IT systems, tools and technologies. At times, this can create an all-eggs-in-one-basket situation, where a single security breach can completely cripple an entire company. As such, it's more important than ever for businesses to keep a clear and steady eye on the status of their security controls. This goes well beyond the occasional security review. IT systems are constantly changing. And whether the changes are expected (such as incorporating a new tool into the ecosystem) or unexpected (such as a failure in the software), businesses need to be able to keep up with changes as they occur.
Continuous monitoring exists to provide IT organisations with real-time insights to inform immediate threat response. At any given time, organisations have a direct view into how their security controls are operating and whether their system is at risk. Top continuous monitoring solutions also provide flexibility, reliability and response options to address any threats that might arise.
Overall, the goal of internal continuous monitoring is to ensure that all relevant IT assets are operating within established parameters of risk and compliance. More specifically, the objectives of continuous monitoring may be defined as follows:
Continuous monitoring is essentially 24/7 surveillance for network activity. When suspicious, non-compliant or otherwise unauthorised activity occurs, continuous monitoring provides optimal transparency and gives organisations a chance to respond.
As previously addressed, continuous monitoring goes hand in hand with risk management. A primary function of continuous monitoring is providing reliable data insights to help identify, respond to and eliminate emergent threats.
Built-in system alerts can help companies identify breaches and other threats immediately, allowing them to respond just as quickly to mitigate the risk before it can cause serious damage.
IT risk goes beyond data theft; under-performing applications and unexpected system downtime also pose a threat to IT organisations. Internal continuous monitoring helps detect performance issues and track them back to their root causes.
IT system changes don't only affect businesses; they affect customers as well. Continuous monitoring of user behaviour within the system provides valuable customer-experience feedback, so organisations can determine which updates are affecting which users.
In line with the objectives associated with continuous monitoring, there are several advantages that IT organisations may enjoy. These include the following:
Backed by reliable security and compliance insights, and working within an effective risk management framework, businesses can automate essential authorisations, processes and responses. This frees up valuable experts and resources for use in other essential tasks.
Continuous monitoring is nothing less than continuous visibility. Controls, vulnerabilities, plans, risks, performance and more are all fully up to date and on display, providing decision-makers with the vital insights they need.
Unanticipated risks, performance problems and non-compliance issues can slow the growth of any business. Continuous monitoring makes these concerns a non-issue and helps IT organisations enjoy better returns, more quickly.
Given the complexity of most IT ecosystems, some companies may have concerns about how best to get started with continuous implementation. To help simplify the process and make it more accessible, continuous monitoring can be broken down into five individual steps:
It may be easy to say that all information systems fall under the banner of a specific continuous-monitoring deployment, but the reality is that there will likely be some grey areas in terms of what to include and what to exclude. With this in mind, the first step towards effective monitoring is clearly defining the scope and identifying the systems that will require continuous monitoring.
Not all IT assets are created equal, and not all IT assets carry the same risks. As part of the continuous-monitoring deployment, IT organisations must individually assess every asset to determine the types and levels of security controls each will need. Higher-risk assets will naturally require stricter security, while some no- or low-risk assets may not require much security at all.
After performing the asset risk assessments mentioned above, the organisation must then act on this information, pairing each asset with the correct security controls tailored to individual risk levels. These controls can range from simple to advanced, and should provide a more-effective network security posture customised to each specific asset, as well as the system as a whole.
With control applications firmly in place, the organisation can finally begin configuring their continuous-monitoring tool to collect relevant application data. Using log aggregation capabilities to capture log files from assets on the network, organisations create an ongoing, real-time record of everything that's happening on the network. This information can then be used to detect emergent threats, identify areas of non-compliance and measure performance against established metrics.
Once the monitoring tool has been configured and deployed, the final step is for the organisation to simply continue monitoring and assessing their network. When functioning correctly, continuous monitoring will potentially produce millions of data points; to ensure that these points aren't overlooked, most businesses choose to incorporate big-data analytics, machine learning and other technologies. This helps guarantee that when abnormal network activity occurs, it doesn't slip past the security net.
