Understanding Intruders and Their Threats to Computer Security

An intruder is a person who enters a place without permission or authorization, often with the intention of committing a crime or causing harm. In the context of computer security, an intruder can be a hacker or other malicious actor who attempts to gain unauthorized access to a computer system or network.

Intruders can use various methods to gain access to a system, such as using stolen login credentials, exploiting vulnerabilities in software or hardware, or using social engineering tactics to trick users into revealing sensitive information. Once an intruder has gained access to a system, they can potentially cause a range of problems, including stealing sensitive data, installing malware, or disrupting the normal functioning of the system.

To protect against intruders, organizations often use various security measures, such as firewalls, antivirus software, and encryption. They may also implement strict access controls, such as multi-factor authentication, to ensure that only authorized users can access sensitive systems and data. Additionally, organizations may monitor their networks for suspicious activity and use incident response plans to respond quickly and effectively in the event of a security breach.
