The Importance of Information Security Metrics in Cyber Security
As human society becomes increasingly digitized, cyber security is critical to business operations. The world’s most critical infrastructure, including healthcare, financial institutions, government agencies and manufacturing, rely on computers and connected devices for key functions such as communication, processing and storage of data and software applications. But these devices and their operating systems are vulnerable to attacks from hackers who can target businesses for profit, extortion or vandalism, as well as political and social motives (like hacktivism) and the growing number of state-sponsored actors.
As a result, cyber security teams must continually monitor and protect against threats that are constantly evolving. To do so, they rely on information security metrics – measures used to identify and evaluate cybersecurity risks, such as the probability of a loss event multiplied by the magnitude of the loss that would occur. This allows them to prioritize their cyber risk mitigation efforts based on business impacts.
The best way to avoid cyberattacks is to keep operating systems, software and other hardware up to date with the latest patches. Also, users should use strong passwords that are unique and have a combination of letters, numbers, special characters and lower-case and upper-case words.
Security teams can further protect their networks by monitoring and analyzing the percentage of web or network traffic that is not originating from human users. This metric, known as non-human traffic or bot activity, is an important indicator of potential cyberattacks. Managed Detection and Response
