Security Response Planning is on the Rise

IBM Security announced the results of a global report examining businesses' effectiveness in preparing for and responding to cyberattacks. While organizations surveyed have slowly improved in their ability to plan for, detect and respond to cyberattacks over the past five years, their ability to contain an attack has declined by 13% during this same period.

The global survey, conducted by Ponemon Institute, 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. While security response planning is slowly improving, the vast majority of organizations surveyed (74%) are still reporting that their plans are either ad-hoc, applied inconsistently, or that they have no plans at all. 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.

More surveyed organizations have adopted formal, enterprise-wide security response plans over the past 5 years of the study; growing from 18% of respondents in 2015, to 26% in this year's report (a 44% improvement). Even amongst those with a formal security response plan, only one third (representing 17% of total respondents) had also developed specific playbooks for common attack types and plans for emerging attack methods like ransomware lagged even further behind.

The amount of security tools that an organization was using had a negative impact across multiple categories of the threat lifecycle amongst those surveyed. Organizations using 50+ security tools ranked themselves 8% lower in their ability to detect, and 7% lower in their ability to respond to an attack, than those respondents with less tools. Companies with formal security response plans applied across the business were less likely to experience significant disruption as the result of a cyberattack. Over the past two years, only 39% of these companies experienced a disruptive security incident, compared to 62% of those with less formal or consistent plans.

The survey found that even amongst organizations 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 organizations with consistent and repeatable action plans for the most common attacks they are likely to face.

Amongst the minority of responding organizations who do have attack-specific playbooks, the most common playbooks are for DDoS attacks (64%) and malware (57%). 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,2 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. With business operations changing rapidly due to an increasingly remote workforce, and new attack techniques constantly being introduced, this data suggests that businesses may be relying on outdated response plans which don't reflect the current threat and business landscape.

The report also found that complexity is negatively impacting incident response capabilities. Those surveyed estimated their organization 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 organizations 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).
