A security breach occurs when an intruder gains unauthorized access to a computer system or network. This can happen through a variety of means, such as exploiting a vulnerability in the system, stealing a password, or using social engineering techniques to trick an authorized user into divulging sensitive information.
Once an attacker has gained access to a system, they may attempt to escalate their privileges to gain even more control. This can allow them to access sensitive data, install malicious software, or even disable the system entirely.
A security breach can have serious consequences for an organization, such as financial loss, damage to reputation, and loss of customer trust. In some cases, it may even be required by law to disclose a breach to affected individuals.
To prevent security breaches, organizations should implement strong security measures, such as two-factor authentication, data encryption, and regular security audits. They should also educate their employees on security risks and best practices for avoiding them.
