Computer network intrusion refers to the unauthorized and deliberate act of gaining unauthorized access to a computer network or systems by an individual or entity. It involves bypassing security measures to gain access to confidential information, disrupt network operations, or conduct malicious activities.
Computer network intrusion can occur through various methods, such as exploiting vulnerabilities in software or hardware, employing brute force attacks, phishing, malware, or using stolen or compromised credentials. It is typically done with the intent of stealing sensitive data, causing damage, disrupting services, or sabotaging systems.
The purpose of a computer network intrusion can vary, ranging from personal gain, industrial espionage, political motives, activism, or cyber warfare. Intruders may seek to access financial information, personal records, trade secrets, intellectual property, or classified information.
To counter computer network intrusions, organizations utilize various security measures such as firewalls, intrusion detection systems (IDS), encryption, and access controls. Additionally, regular system updates, employee training, and strong password policies are crucial in fortifying network security.
The consequences of successful network intrusions can be severe, including financial losses, reputational damage, legal ramifications, compromised privacy, and disruption of operations. Governments, businesses, and individuals worldwide face an ongoing challenge in safeguarding computer networks against intrusions, as cybercriminals consistently devise new methods to breach security systems and networks.
