Questions and Answers

What is a primary function of IPsec beyond encryption?

  • Managing network bandwidth
  • Providing mutual authentication (correct)
  • Monitoring network traffic patterns
  • Establishing secure email communication
  • Which of the following protocols can be encrypted using IPsec?

  • SMTP
  • FTP
  • HTTP
  • RDP (correct)
  • How does IPsec differ from SSL in terms of authentication?

  • IPsec uses certificates while SSL relies on usernames and passwords
  • Both use the same authentication mechanisms
  • SSL allows for more flexible authentication methods than IPsec
  • IPsec requires mutual authentication while SSL does not (correct)

    Study Notes

    Internet Protocol Security (IPsec)

    • IPsec is built into Windows, not an extra software
    • It's not just for VPNs
    • Provides encryption and integrity for network services
    • Requires mutual authentication for access
    • Used to control access to TCP/UDP ports based on user groups in Active Directory
    • Can be used to create protected networks like internal VLANs
    • Works with host-based firewalls for improved security

    IPsec Features

    • 256-bit AES packet encryption
    • Packet digital signatures for integrity and proof of origin
    • Mutual authentication with Kerberos or certificates

    IPsec Benefits

    • Encrypts common protocols like RPC, SMB, DNS, LDAP, RDP, VNC, and PowerShell Remoting
    • Limits access to network services based on user groups for Zero Trust security
    • Protects network services even outside the main perimeter firewall
    • Creates secure connections even without a VPN
