Establishing a modern business requires facing several important facts, the most prominent of which is that cyberattacks have become a matter of when not if. In this era where cyber threats now lurk around every corner, organisations must prepare for such an inevitability as best they can by shoring their defences with the help of reputable cybersecurity services.
Beyond that, it is also vital to formulate a comprehensive incident response team and plan and test its efficacy before an actual attack takes place. This latter step involves identifying what works and what doesn’t, making any necessary optimisations to resource allocation, and highlighting the incident response programme’s value and effectiveness to stakeholders through a set of metrics. Read on as we explore what these metrics are and why they matter.
Cybersecurity incident response metrics provide a quantitative measurement of how well an organisation's response plan performs in the event of an attack and offer invaluable insights into the many aspects of its processes, from detection to recovery. Tracking these metrics over time allows business owners to accurately determine the efficiency of their incident response efforts, which ultimately leads to more informed decisions on how to bolster the company's cybersecurity posture. This may include working with a Singapore penetration testing company to constantly root out cybersecurity gaps or something simpler like reworking certain processes of the response plan. The most critical metrics to take note of include:
The average time required to respond to a cybersecurity incident and mitigate its effects upon detection. The lower the time, the faster and more effective an incident response plan is.
This metric shows how long it takes for a business to fix the issues caused by the contained threat. Much like mean time to respond, lower timings signify an incredible capability to resolve disruptions and resume normal operations for end users.
Unlike the previous two, this metric takes a more holistic view that takes into account everything from threat detection to isolation. Low numbers reflect a good and efficient response that can significantly mitigate downtime and business disruption.
This measurement is a percentage of incidents that were contained successfully and kept from spreading further to other networks or IT systems.
The elapsed time before affected systems or services are fully restored following a cybersecurity incident.
A calculation of the average financial impact caused by cyber incidents which covers factors like data recovery costs, lost productivity, and reputational damage.
This is a percentage of all cyber threats that were resolved on initial contact, with higher rates indicating efficient troubleshooting protocols and a well-trained team that can execute them perfectly.
1. Set clear objectives and the appropriate metrics
Having clear and defined goals for what an incident response programme should achieve is imperative, whether it be speeding up resolution times, minimising disruptions, or reducing the financial impact of incidents. With these objectives established, organisations can ensure their metrics will be accurate and relevant to their needs, providing the actionable insights necessary for improvement. When setting these goals, consider factors like the type of attacks that the company is most susceptible to, the appropriate measures to mitigate them, and how much time and resource allocation is required for each.
2. Gather good data
Good information relies on quality data, hence the importance of having reliable data sources for calculating your chosen metrics. These sources typically include incident response tools, security logs, and team reports. Even employee login and log-out records can be incredibly helpful in determining patterns and identifying potentially malicious access attempts.
3. Perform constant monitoring and analysis
An effective way of identifying areas for improvement is by regularly monitoring your chosen metrics and collating the data into reports on a periodic basis. Convert these metrics and performance insights into a more easily digestible format, like charts and graphs, for sharing with key stakeholders to ensure they're always in the loop.
4. Compare results against industry standards
It is best practice to benchmark your incident response metrics against industry standards to fully gauge how the organisation compares to the competition. Doing so offers another means to determine where you fall short and what needs to be worked on to close the gap with them.
5. Iterate, improve, repeat
An organisation's strategic priorities and cybersecurity landscape never stay the same. Therefore, it is critical to adapt your measurement approach using previous feedback and evolving threats to refine and review the efficacy of incident response metrics continuously.
A good incident response plan is more than just resolving incidents and rarely is it perfect from the get-go. Rather, it is strengthened through trial by fire, wherein organisations leverage every attack to make their incident response increasingly more resilient. With the help of cyber incident response metrics, this endeavour becomes more streamlined and provides invaluable intelligence to stay a step ahead in cybersecurity.
If the metrics indicate that your cyber incident response programme could use a leg up, Group8's offensive-inspired solutions may be exactly what you need. From penetration testing to data loss prevention, network security, blockchain security, and more, we offer a complete cyber defence ecosystem that can meet all your security needs and then some.
