- Incident response team (IRT) A group of individuals trained and equipped to handle security incidents. IRTs are typically composed of IT and security professionals who have the knowledge and expertise to respond to a wide range of security threats. An example of an IRT could be a group of cybersecurity analysts and engineers who are responsible for identifying and mitigating cyberattacks within an organization.
- Incidents An event that poses a potential threat to the confidentiality, integrity, or availability of an organization's information or systems. Incidents can include anything from a data breach to a malware infection to a phishing attack. It is important for organizations to have processes in place to identify and respond to incidents in order to prevent or minimize potential damage.
- Incomplete parameter checking Incomplete parameter checking occurs when a software application does not fully validate user input, which may lead to vulnerabilities such as SQL injection, buffer overflows, or cross-site scripting (XSS). These vulnerabilities can be exploited by attackers to manipulate the application, gain unauthorized access, or compromise data integrity.
- Inconsequential deficiency A security weakness that does not have a significant impact on the overall security of the system. These deficiencies are typically low-risk and do not require immediate attention but should still be addressed in order to maintain the overall security of the system. An example of an inconsequential deficiency might be a weak password policy that does not require complex passwords but does not pose a significant threat to the security of the system.
- Incremental backup A backup strategy that involves creating backups of only the data that has changed since the last backup. This can save time and storage space, as only the changes need to be backed up rather than the entire system. An example of incremental backup might be a system that creates daily backups of only the files that have been modified since the previous day's backup.
- Incremental testing A testing strategy that involves breaking down a complex system into smaller, manageable pieces and testing each piece individually. This can help to identify defects early on and make it easier to isolate and fix problems. An example of incremental testing might be a software development team that tests individual components of the system before integrating them into the final product.
- Independence In the context of IT, independence refers to the self-sufficiency of a system or operation, such that it can function without external dependencies or interventions. This is critical for system stability and security, as it reduces reliance on third-party systems that could become single points of failure or introduce additional security vulnerabilities.
- Indicator A piece of information that can be used to detect or identify a potential security threat. Indicators can come in many forms, including suspicious behavior, unusual network traffic, or specific patterns in data. An example of an indicator might be a sudden increase in login attempts from a specific IP address, which could indicate a brute-force attack.
- Individual accountability The practice of holding individuals accountable for their actions, including any security breaches or violations. This can help to ensure that employees take responsibility for their actions and can help to prevent security incidents by creating a culture of accountability within the organization. An example of individual accountability might be requiring employees to sign a security policy acknowledging their responsibility to protect company data.
- Industrial Control Systems (ICS)Systems that are used to control and monitor industrial processes, such as manufacturing, power generation, and transportation. ICS can be vulnerable to cyber-attacks, which can disrupt critical infrastructure and cause significant damage. An example of an ICS might be a system that controls the flow of oil or gas through a pipeline.
