and limited traffic flow confidentiality. • IPsec has government and industry support.
• IPsec allows corporations to select security services
according to internal security policies.
VPN IPsec IKE v2 TLS M. Mogollon – 01/08 - 12 • IPsec protects traffic transparently on IP packet level.
o The operation is completely transparent to the user; no changes in applications, no additional
procedures or learning by the user required.
• IPsec is "Native-IP”; it is not limited to e.g. operating system specific solutions.
o IPsec will be everywhere IP is, unlike tunneling protocols that can typically only be found in
specific operating systems,. It will also be a mandatory part of the forthcoming IPv6
• IPsec has a wide variety of strong encryption standards.
o Unlike previous solutions, IPsec is a standard where security has been the number one design
criteria resulting in unbeatable security.
• IPsec includes a secure key management solution with digital certificate support.
o IPsec guarantees ease of management and use, even in large scale networks, and highly
secure authentication of parties.
• IPsec has the widest government and industry support, the latter including leaders in industry
such as Entrust, Nortel Networks, Cisco, Microsoft, Network Associates, CheckPoint Software,
o A wide, guaranteed deployment ensures interoperability and availability of secure solutions
for all needs of corporate and private users.
• IPsec is not a single protocol. Instead, IPsec provides a set of security algorithms plus a general
framework that allows a pair of communicating entities to use whichever algorithms provide
security appropriate for the communication. 12 VPN, IPSec and TLS Internet Protocol (IP) – Security Threats
