Study Notes
Network Security Goals and Importance
- The primary goal of network security is to protect the integrity, confidentiality, and availability of computer systems and data from unauthorized access, use, disclosure, disruption, modification, or destruction.
- Network security is important for individuals, businesses, and governments as it safeguards sensitive information and prevents financial losses, reputational damage, and legal liability.
Common Sources of Vulnerabilities
- Human error, such as weak passwords, phishing, and social engineering, is a common source of vulnerability in network security.
- Outdated or unpatched software and hardware, as well as poorly configured systems, can also lead to vulnerabilities.
Evolution of Network Security
- In the past, networks were typically designed with a focus on functionality and performance, overlooking security concerns.
- The growing Internet and its associated security risks led to the introduction of technologies like firewalls and intrusion detection systems.
Balance in Network Security
- A crucial balance between security, functionality, and usability is necessary in modern network security to ensure that protection measures do not hinder the performance of the network.
Drivers of Network Security
- The increasing use of Local Area Networks (LANs) and personal computers drove the need for network security measures to protect against unauthorized access and data breaches.
- The use of extranets, which connect multiple organizations' networks, led to the need for additional security controls to prevent unauthorized access and data sharing.
Purpose of Network Security
- The primary purpose of network security is to prevent unauthorized access, use, disclosure, disruption, modification, or destruction of computer systems and data.
