What methods ensure the security of network connections?

Network connection security is ensured by several methods:

• Data encryption — using protocols such as TLS/SSL to protect information from interception.
• Authentication — verifying the identity of users and devices (passwords, certificates, two-factor authentication).
• Using VPN — creating a secure communication channel over public networks.
• Firewalls and traffic filtering — restricting network access and blocking suspicious connections.
• Data integrity control — applying hash functions and digital signatures to detect changes.
• Software updates and patching — fixing vulnerabilities that could be exploited for attacks.

These methods collectively help protect network connections from unauthorized access and attacks.
