IBM Security announced the results of a global report examining businesses’ effectiveness in preparing for and responding to cyberattacks. Organisations ability to contain an attack has declined by 13% during this same period over the past five years while they are reported to have slowly improved in their ability to plan for, detect and respond to cyberattacks. The global survey conducted by Ponemon Institute and sponsored by IBM Security found that respondents’ security response efforts were hindered by the use of too many security tools, as well as a lack of specific playbooks for common attack types.
The vast majority of organisations surveyed (74%) are still reporting that their plans are either ad-hoc, applied inconsistently, or that they have no plans at all while security response planning is slowly improving. This lack of planning can impact the cost of security incidents, as companies that have incident response teams and extensively test their incident response plans spend an average of $1.2 million less on data breaches than those who have both of these cost-saving factors in place.
The key findings of those surveyed from the fifth annual Cyber Resilient Organization Report include:
"While more organizations are taking incident response planning seriously, preparing for cyberattacks isn’t a one and done activity," said Wendi Whitmore, Vice President of IBM X-Force Threat Intelligence. "Organizations must also focus on testing, practicing and reassessing their response plans regularly. Leveraging interoperable technologies and automation can also help overcome complexity challenges and speed the time it takes to contain an incident.”
Updating Playbooks for Emerging Threats
The survey found that even amongst organisations with a formal cybersecurity incident response plan (CSIRP), only 33% had playbooks in place for specific types of attacks. Since different breeds of attack require unique response techniques, having pre-defined playbooks provides organisations with consistent and repeatable action plans for the most common attacks they are likely to face.
The most common playbooks are for DDoS attacks (64%) and malware (57%) amongst the minority of responding organisations who do have attack-specific playbooks. While these methods have historically been top issues for the enterprise, additional attack methods such as ransomware are on the rise. While ransomware attacks have spiked nearly 70% in recent years, only 45% of those in the survey using playbooks had designated plans for ransomware attacks.
Additionally, more than half (52%) of those with security response plans said they have never reviewed or have no set time period for reviewing or testing those plans. This data suggests that surveyed businesses may be relying on outdated response plans which don’t reflect the current threat and business landscape with business operations changing rapidly due to an increasingly remote workforce, and new attack techniques constantly being introduced.
More Tools Led to Worse Response Capabilities
The report also found that complexity is negatively impacting incident response capabilities. Those surveyed estimated their organisation was using more than 45 different security tools on average, and that each incident they responded to required coordination across around 19 tools on average. However, the study also found that an over-abundance of tools may actually hinder organisations ability to handle attacks. In the survey, those using more than 50 tools ranked themselves 8% lower in their ability to detect an attack (5.83/10 vs. 6.66/10), and around 7% lower when it comes to responding to an attack (5.95/10 vs. 6.72/10).
These findings suggest that adopting more tools didn’t necessarily improve security response efforts — in fact, it may have done the opposite. The use of open, interoperable platforms as well as automation technologies can help reduce the complexity of responding across disconnected tools. 63% said the use of interoperable tools helped them improve their response to cyberattacks amongst high-performing organisations in the report.
Better Planning Pays Off
This year’s report suggests that surveyed organisations who invested in formal planning were more successful in responding to incidents. Only 39% experienced an incident that resulted in a significant disruption to the organisation within the past two years compared to 62% of those who didn’t have a formal plan in place amongst respondents with a CSIRP applied consistently across the business.
Security workforce skills were found to be a top factor when looking at specific reasons that these organisations cited for their ability to respond to attacks. 61% of those surveyed attributed hiring skilled employees as a top reason for becoming more resilient; amongst those who said their resiliency did not improve, 41% cited the lack of skilled employees as the top reason.
Technology was another differentiator that helped organizations in the report become more cyber resilient, especially when it comes to tools that helped them resolve complexity. Looking at organisations with higher levels of cyber resilience, the top two factors cited for improving their level of cyber resilience were visibility into applications and data (57% selecting) and automation tools (55% selecting). Overall, the data suggests that surveyed organisations that were more mature in their response preparedness relied more heavily on technology innovations to become more resilient.
