A cyber asset refers to any device, solution, or service that makes up an organization’s attack surface. It can thus be a computer, a tablet, a smartphone, a cloud service, a software, an app, or data accessible via a network or the Internet.

Think of it as anything you own, also known as your “assets.” You would never want anyone with malicious intent to get their hands on any of them. That’s also true for cyber assets. If malicious actors get to them, your organization suffers.

Such assets have become a must for organizations of all sizes, given that we live in the digital age. Learn more about them here.

What Are the Different Types of Cyber Assets?

These assets can be categorized into devices, network components, applications, data, users, and intelligence.

Devices include computers, mobile phones, tablets, printers, Internet of Things (IoT) devices, virtual machines (VMs), and cloud hosts, among many others. Network components, meanwhile, include network interfaces, IP addresses, firewalls, gateways, domains, and certificates, to name a few. Applications include all the software and apps an organization owns. Data refers to all the information a company keeps, including where they are stored. Finally, intelligence refers to all the data an organization accesses (e.g., threat intelligence, logs, etc.) for their operations.

Types of Cyber Assets

Given the current state of the cybersecurity landscape, however, all digital assets need protection against threats, which has given rise to cyber asset attack surface management (CAASM).

What Is Cyber Asset Attack Surface Management?

CAASM helps organizations identify and manage potential vulnerabilities and weaknesses in their digital assets. Today, various vendors offer CAASM tools to help organizations understand and reduce their points of exposure to cyber attacks, thus enhancing their overall cybersecurity.

Understanding why CAASM is important requires understanding what an attack surface is.

What Is an Organization’s Attack Surface?

Everything that can serve as a target for cyber attackers makes up an organization’s attack surface. It is the total of all the possible points or attack vectors that unauthorized users can access to get to a system and extract data. The bigger the attack surface is, the more threat entry points there are. And that makes CAASM a must.

How Can an Organization Protect Its Cyber Assets?

Protecting one’s digital assets requires safeguarding two specific things—data and systems and services.

Data Protection

Today, protecting personal information is critical not only to avoid data theft and loss due to cyber attacks but also to safeguard one’s reputation and evade noncompliance penalties and other financial losses. The personal data organizations keep may include financial information, medical records, and private communications, which, when lost, can lead to identity theft and other nasty repercussions.

Companies can protect data by implementing strong security measures, such as encryption, password security, and multifactor authentication (MFA).

System and Service Protection

Cyber attackers have a sole goal in mind—to cause an organization trouble. They disrupt operations, damage systems, and steal data. In some cases, they can even lead to the closure of a business.

Companies can mitigate the risks cyber attacks cause by implementing comprehensive cybersecurity measures and tools, including firewalls, intrusion detection systems (IDSs), regular software updates, employee training, and incident response plans.

Here are the top cybersecurity best practices organizations should implement.

  1. Implement robust cybersecurity strategies.
  2. Update and strictly enforce security policies.
  3. Install security updates and back up data.
  4. Use strong passwords and MFA.
  5. Conduct regular cybersecurity audits.
  6. Work with your IT and security departments to prevent cyber attacks.
  7. Control access to sensitive information.
  8. Monitor third-party users and applications.
  9. Train employees on cybersecurity.
  10. Encrypt all data belonging to employees, customers, suppliers, partners, and other stakeholders.

Cyber assets constantly change. What works now may not be true tomorrow. Thus, it is necessary to monitor them for the slightest shifts and update the corresponding protective measures and solutions.
