ISO Asset Management and Cybersecurity: Protecting Your Assets in the Digital Age
Businesses increasingly rely on digital assets to run their operations in today's digital world. As these assets' value grows, so does the risk of cyber threats.
Organizations must implement robust asset management practices to protect their digital assets from cyber-attacks.
This article will explore how ISO Asset Management, specifically ISO 27001, can help organizations protect their digital assets from cyber threats.
Understanding Cybersecurity Asset Management (CSAM) for Industrial Control Systems
Cybersecurity asset management, or CSAM, is an essential practice that helps organizations safeguard their assets against cyber threats. While asset management can include people and processes within an organization, its primary focus is identifying, managing, and securing computerized systems, including hardware and software.
Asset management begins with identifying all the computerized systems in an industrial control environment and proactively managing additions, removals, and changes to those devices.
There are several types of Operational Technology (OT) devices:
Engineering Workstations (EWS)
Supervisory Control and Data Acquisition (SCADA)
Human-Machine Interfaces (HMI)
Programmable Logic Controllers (PLC)
Remote Terminal Units (RTUs)
Organizations must identify which OT devices need protection to implement a robust cybersecurity program.
It's common for organizations to maintain some form of automated asset inventory management for their Information Technology (IT) systems. Still, many don't deploy them in their OT environments due to the intrusive nature of IT tools. However, highly specialized passive OT monitoring technologies are available that can minimize attack vectors by performing asset discovery, vulnerability management, and much more.
Types of Cyber Threats and Their Risks in Asset Management
With the proliferation of digital technology, the risk of cybercrime has become more widespread.
The consequences of cyber threats can be severe, especially when proper cybersecurity asset management is not in place. Companies must be proactive in their approach to cybersecurity to prevent significant harm to their assets.
Common types of cyber threats:
Data breaches
Data breaches are serious cybersecurity threats that severely affect a company's assets.
They occur when an unauthorized person gains access to sensitive data, such as customer information, financial data, or intellectual property.
Data breaches can result in a loss of trust among customers and stakeholders, leading to a loss of revenue for the company.
Malware
Malware, short for "malicious software," is a type of cyber threat that can cause significant damage to an organization's assets if not correctly managed.
Malware is designed to infiltrate a computer system or network, carry out malicious activities, steal sensitive information, damage software, hardware, or data, and render entire systems unusable.
Types of malware include viruses, Trojan horses, worms, and spyware.
Phishing attacks
Phishing attacks are social engineering attacks that deceive individuals into divulging sensitive information.
The attackers often use fake emails, text messages, or social media messages that appear legitimate and from trustworthy sources, such as banks, government agencies, or popular online services. The messages often contain urgent or enticing requests, such as asking the recipient to verify their account information or offering a fake prize or gift.
Phishing attacks are particularly effective because they exploit human weaknesses like trust, curiosity, and urgency. They can also be challenging to detect, as the messages and websites used in the attacks often look legitimate and convincing. As a result, individuals may unwittingly disclose sensitive information or download malicious software, such as keyloggers or spyware, onto their devices.
Organizations can protect their employees and assets from phishing attacks by implementing security policies and providing regular training on cybersecurity awareness and best practices like:
Email filters to block suspicious messages
Enforcing password policies
Conduct simulated phishing exercises to educate employees on recognizing and avoiding phishing attempts.
By being vigilant and proactive, organizations and individuals can prevent the potentially devastating consequences of phishing attacks.
Ransomware
Ransomware is malware that encrypts a company's data and demands a ransom payment in exchange for the decryption key.
Once a system is infected, the attackers can lock down the entire system, making it inaccessible to the company until the ransom is paid.
If a company's data is not backed up or the backups are also infected, the company may have no choice but to pay the ransom to regain access to its data leading to significant financial losses and damage to its reputation.
DoS (Denial-of-Service) attacks
DoS attacks overload a company's network or system, making it unavailable to users. The attacker does this by flooding the network or system with overwhelming traffic, slowing it down, or crashing it.
Organizations must prioritize cybersecurity in their asset management policies to safeguard their assets from potential harm caused by cyber threats by implementing regular security audits, employee training, and the latest security technologies. Failure to do so can result in reputational damage, loss of revenue, and legal consequences.
An effective and trusted asset management standard to adopt is ISO 27001.
Hack-Proof Your Business: The Benefits of ISO 27001 Compliance for Asset Management
ISO 27001 is an international standard for information security management. It provides a comprehensive framework for managing and protecting digital assets, including sensitive information, financial data, and intellectual property.
The standard covers asset management, risk management, and information security controls, helping organizations identify and implement controls to manage those risks effectively.
The benefits of ISO 27001 standards are as follows:
Systematic and proactive
This approach helps organizations identify potential risks and implement controls to mitigate them before they can cause any harm. By taking this approach, companies can avoid costly security incidents and the reputational damage that comes with them.
