Global spam volume is rising: Cisco 2017 Annual Cybersecurity Report

BENGALURU: According to the Cisco 2017 Annual Cybersecurity Report (ACR), over one-third of organizations that experienced a breach in 2016 reported substantial customer, opportunity and revenue loss of more than 20 percent.

“In 2017, cyber is business, and business is cyber –that requires a different conversation, and very different outcomes. Relentless improvement is required and that should be measured via efficacy, cost, and well managed risk. The 2017 Annual Cybersecurity Report demonstrates, and I hope justifies, answers to our struggles on budget, personnel, innovation and architecture,” says John N. Stewart, Senior Vice President and Chief Security and Trust Officer, Cisco.

Ninety percent of these organizations are improving threat defense technologies and processes after attacks by separating IT and security functions (38 percent), increasing security awareness training for employees (38 percent), and implementing risk mitigation techniques (37 percent). The report surveyed nearly 3,000 chief security officers (CSOs) and security operations leaders from 13 countries in the Security Capabilities Benchmark Study, part of the Cisco ACR.

Now in its 10th year, the global report highlights challenges and opportunities for security teams to defend against the relentless evolution of cybercrime and shifting attack modes. CSOs cite budget constraints, poor compatibility of systems, and a lack of trained talent as the biggest barriers to advancing their security postures. Leaders also reveal that their security departments are increasingly complex environments with 65 percent of organizations using from six to more than 50 security products, increasing the potential for security effectiveness gaps.

To exploit these gaps, ACR as presented data that shows criminals leading a resurgence of “classic” attack vectors, such as adware and email spam, the latter at levels not seen since 2010. Spam accounts for nearly two-thirds (65 percent) of email with eight to 10 percent cited as malicious. Global spam volume is rising, often spread by large and thriving botnets.

Measuring effectiveness of security practices in the face of these attacks is critical. Cisco says it tracks progress in reducing “time to detection” (TTD), the window of time between a compromise and the detection of a threat. Faster time to detection is critical to constrain attackers’ operational space and minimize damage from intrusions. Cisco has successfully lowered the TTD from a median of 14 hours in early 2016 to as low as six hours in the last half of the year. This figure is based on opt-in telemetry gathered from Cisco security products deployed worldwide.
