2018 Security Threat Report

2018 Security Threat Report Assessing Nine Years of Cyber Security Vulnerabilities and Exploits Internal Audit, Risk, Business & Technology Consulting Executive Summary Finding the right words to describe the magnitude of cyber security today is like trying to define the size and splendor of the Grand Canyon to someone unfamiliar with the natural wonder of the world. News of massive data breaches continues to make headlines. Among the largest breaches to date, one of the major consumer credit reporting agencies announced last year that hackers accessed its store of Social Security numbers, driver’s license data, birth dates and other personal information on more than 140 million consumers. A decade ago, such news would have been unimaginable. But sadly, over the last several months, disclosures of significant cyber security breaches have become routine as organizations increasingly rely on vulnerable digital technologies and third-party service providers. At the same time, cyber criminals are becoming more In addition, we provide insight into the root causes creative and sophisticated. New cyber threats emerge underlying the vulnerabilities and practical guidance daily that put any number of business systems at on how companies can protect their information. risk, and companies face a monumental challenge to In these times of digital treachery, we hope you find keep pace with the threats and safeguard their data, this report useful. particularly their “crown jewels.” It’s no surprise that cyber security is the chief concern not only for CIOs and IT departments, but also for executive-level Key calls to action we define include: management and boards of directors. This report aims to help organizations address and Strong permission and user access controls understand the cyber security landscape by exploring 01 and detailing the most common digital threats today. Since 2009, Protiviti security labs in the United States Employee security awareness have performed more than 500 in-depth security 02 scans on behalf of a broad range of organizations to test and assess their IT systems and infrastructure Patch management for cyber security risks. Keeping the organizations 03 anonymous, we have compiled and quantified the vulnerability and threat discoveries in our data, System configuration management offering insights and trends regarding the types of 04 threats organizations are most likely to face, the most frequently perpetrated cyber crimes, the recent Periodic penetration testing acceleration of attacks, and trends in cyber attacks by 05 industry and size, among other views. protiviti.com 2018 Security Threat Report · 1 About Our Study We compiled the data, analyses and trends presented • The data contains results from those of internet- in this report by reviewing information from security facing systems (external) as well as systems on the vulnerability scans of IT systems of more than 500 inside of the organization’s firewall (internal). organizations in a broad range of industries.

Media and – Healthcare and Life – Vulnerabilities are labeled “Medium” severity if Sciences Telecommunications they have a CVSS base score of 4.0-6.9. Manufacturing – Consumer Products – – Vulnerabilities are labeled “High” severity if they and Services – Education have a CVSS base score of 7.0-8.9. Energy and Utilities – – Vulnerabilities are labeled “Critical” severity if they have a CVSS base score of 9.0-10.0.

Just a few examples include MS08-067, Heartbleed, Shellshock (CVE-2014-6271), MS17-010 and MS15-034. • Organizations are still running a significant number of unsupported systems. • Just under half of the vulnerabilities identified during testing have a publicly available exploit. • There have been consistent challenges with SSL, especially with regard to weak ciphers and diver- sions. Though the raw number of issues hasn’t reached a high level, this is an area for organizations to monitor.
