Network Security
- Network Security posture
Network security is a set of policies, processes, and technologies that protect a computer network from unauthorized access, misuse, or theft. It also protects the data and resources that are accessible through the network.
Network security is important because it protects vital information and operational processes that depend on computer networks and IT systems. Networks face many cyber threats, from unsophisticated hackers to sophisticated intruders.
Some network security measures include:
- Multifactor authentication (MFA)Requires two or more factors to verify a user’s identity. For example, Google Authenticator generates a unique security code that a user enters with their password.
- Network segmentationDefines boundaries between network segments to prevent potential threats from outside the network.
- Data loss prevention (DLP)Uses policies and technologies to track data flows, encrypt sensitive information, and alert users of suspicious activity.
Other network security measures include:
- Firewall
- Access control
- Intrusion detection system
- Proxy server
- Web filter
- Host intrusion prevention
