As companies around the world continue to ramp up their data collection, storage and analysis capabilities, the risk of large-scale cybersecurity incidents grows increasingly severe. Modern cybercriminals utilize a staggering number of hacking techniques to gain access to critical infrastructure and sensitive data stores, capitalizing on network vulnerabilities, human error and lackluster IT security frameworks.

Organizations that take a passive approach to risk management often leave themselves open to data theft and exploitation, which can not only cripple their productivity but also ruin their reputation. To offset the threat of costly data breaches, ransomware and other digital hazards, businesses of all sizes should regularly review their information security standards and stay abreast of new developments in the IT field. But what, exactly, is information security, and how does it protect sensitive data?

Defining information security

Organizations in every industry have come to rely on information technologies to manage their day-to-day operations and often leverage an array of different products and services. Maintaining the security of these IT assets is critical to the success of any business, as a single cybersecurity incident can have a significant impact on their efficiency and profitability. In fact, a 2019 report from Accenture found that the average cost of cybercrime for an organization increased $1.4 million from the previous year and now falls around $13 million in total. A weak information security posture is not just an issue for the company itself, as the theft of sensitive consumer information can lead to massive financial losses for their customers and industry partners.

“The average cost of cybercrime for an independent organization increased $1.4 million between 2017 and 2018.”

According to the National Institute of Standards and Technology, information security is defined as “the protection of information and systems from unauthorized access, use, disclosure, disruption, modification, or destruction in order to provide confidentiality, integrity, and availability.” Businesses typically achieve this objective by establishing a set of comprehensive strategies for managing security risks, internal process, software tools and IT policies. Under the NIST’s cybersecurity framework, organizations should have the capability to detect, document and prevent malicious activities that target their digital and non-digital information. Of course, regular risk assessments are essential to upholding information security standards and mitigating new threats that might not be included in their existing guidelines.

Best practices for information security and risk management

First, it’s important to note that information security standards should be documented in detail, as this provides IT professionals with a clear set of policies for protecting critical infrastructure and making ongoing improvements to an organization’s cybersecurity framework. It’s also crucial to develop robust security controls that can safeguard information assets regardless of how they are formatted, stored or transmitted. While companies can implement a variety of advanced information security management protocols, many adhere to the international standards outlined in the ISO/IEC 27000 guidelines and/or the NIST’s SP 800 series.

ISO/IEC 27000

The ISO/IEC 27000 family of standards is designed to safeguard financial information, intellectual property and employee data through structured cybersecurity controls and vulnerability assessment processes. This approach often involves integrating a layered security framework that manages risk at the system, network, application and transmission levels. Of course, companies in the manufacturing space must also worry about device-level security, as IoT attacks were up 600% in 2017, according to research from Symantec. Generally speaking, organizations of all sizes use the ISO/IEC 27001 standards to create stronger policies for governing people, processes and IT systems cybercriminals may target.

NIST SP 800

The NIST’s special publications on information security offer a variety of general and specialized recommendations for every facet of an organization’s cybersecurity framework, from risk assessment and database governance to access control systems and application whitelisting. These comprehensive documents also provide advanced analysis of pressing security risks that could cause major disruption to organizations’ internal operations and external relationships. Much like the ISO/IEC 27000 family of standards, the NIST’s guidelines are meant to protect the confidentiality, integrity and availability of information assets from malware, data breaches, phishing scams and more.

Minimum requirements for information security programs

A broad-based and balanced information security program is one that addresses the management, operational and technical aspects of safeguarding sensitive data. While it’s true that cutting-edge cybersecurity applications play a pivotal role in IT security frameworks, the most effective programs are built on detailed policies that outline the purpose, scope and goals of every control family. According to the NIST, organizations should integrate the following capabilities into their information security standards:

  • Access controls: Managing access privileges is essential to securing critical infrastructure and protecting key data stores. Implementing access control systems like account management, least privilege, session lock and information flow enforcement can help ensure all users, devices and applications are limited to the transactions and functions they actually need.
  • Awareness and training: The weakest element in any cybersecurity framework is the end-user community, which is why organizations must train their employees on best practices and make them aware of their security responsibilities. Helping workers develop IT skills and knowledge can help prevent a range of common cyberthreats, including malware infections, phishing attempts and more.
  • Configuration management: Maintaining the integrity of information assets and technologies requires IT professionals to strictly control processes for initializing, updating and monitoring system configurations. Organizations should always document their critical infrastructure’s ideal settings and establish baseline configurations for all hardware, software and firmware.
  • Incident response: Even the most well-insulated systems and networks will likely experience a security event at one point in their lifespan, making a well-defined threat identification and response plan crucial to their cybersecurity posture. Organizations should develop operational incident handling capabilities that incorporate detection, analysis, containment and recovery procedures.
  • Risk assessment: Information security is an ongoing process, as new cyberthreats are discovered on what feels like a minute-by-minute basis. By integrating risk assessment protocols like security categorization, vulnerability scanning and real-time monitoring, organizations can remain proactive about their system and network security and quickly identify areas of improvement.
