It is the potential occurrence of an undesirable event that can eventually damage and disrupt the operational and functional activities of an organization.

Threat

Attackers use this to infiltrate and steal data such as personal information, financial information, and login credentials.

Cyber Threats

Attackers can also use this to perform malicious activities and launch further attacks

Compromised System

It refers to a weakness in the design or implementation of a system that can be exploited to compromise the security of the system. It is frequently a security loophole that enables an attacker to enter the system by bypassing user authentication.

Vulnerability

This is the most common vulnerability and is mainly caused by human error, which allows attackers to gain unauthorized access to the system. It may happen intentionally or unintentionally and affect web servers, application platforms, databases, and networks.

Misconfiguration

These are usually user-friendly, especially when the device is being used for the first time, when the primary concern is the usability of the device rather than the device’s security.

Default Installations

These are common software vulnerabilities that happen due to coding errors that allow attackers to gain access to the target system.

Buffer Overflows

An essential component of the infrastructure of any organization. There are several cases where organizations run unpatched and misconfigured servers that compromise the security and integrity of the data in their systems.

Unpatched Servers

Vulnerabilities due to design flaws are universal to all operating devices and systems. Design vulnerabilities, such as incorrect encryption or poor validation of data, are logical flaws in the functionality of the system that attackers exploit to bypass the detection mechanism and acquire access to a secure system

Design Flaws

Due to vulnerabilities in the operating systems, applications such as trojans, worms, and viruses pose threats. These attacks use malicious code, script, or unwanted software, which results in the loss of sensitive information and control of computer operations.

Application Flaws

Open ports and services may lead to the loss of data or DoS attacks and allow attackers to perform further attacks on other connected devices. Administrators must continuously check for unnecessary or insecure ports and services to reduce the risk to the network.

Open Services

Unknown vulnerabilities in software/hardware that are exposed but not yet patched. The attackers exploit these before being acknowledged and patched by the software developers or security analysts.

Default Passwords

These are exposed from old or familiar code. However, they could cause costly data breaches for organizations. Using these outdated codes, attackers can easily discover zero-day vulnerabilities in the system or software that are not yet patched.

Legacy Platform Vulnerabilities

This plays a major role in providing security to any organization’s resources and infrastructure from various internal and external threats.
