  • K75106155: Configuring OCSP Stapling (13.X - 16.X)
    K75106155: Configuring OCSP stapling (13.x - 16.x) Non-Diagnostic Original Publication Date: Feb 13, 2019 Update Date: Sep 3, 2021 Topic This article applies to BIG-IP 13.x - 16.x. For information about other versions, refer to the following article: K17111035: Configuring OCSP stapling (11.x - 12.x) You should consider using this procedure under the following condition: You want to configure the BIG-IP system to use Online Certificate Status Protocol (OCSP) stapling. Description OCSP The original OCSP implementation described in RFC 2560 requires that client applications perform a DNS and an OCSP request, using either HTTP or HTTPs, during the Secure Socket Layer (SSL)/Transport Layer Security (TLS) handshake to validate a secure website's SSL certificate revocation status. The additional DNS and HTTP/HTTPs requests made during the SSL/TLS handshake causes noticeable performance delays for client applications and significantly increases network traffic and processing overhead for the validating OCSP responders. OCSP is introduced to improve SSL/TLS handshake performance while maintaining security. OCSP stapling OCSP stapling (described in RFC 6066 and RFC 6960) is a performance improvement to the original OCSP internet protocol used to verify SSL certificate revocation status. When a secure web server implements OCSP stapling and a remote client application makes a new SSL connection, the secure web server queries the OCSP responder and obtains a signed and time-sensitive OCSP response during the SSL/TLS handshake. The secure web server then responds to the client application on behalf of the OCSP responder, sending (or stapling) the OCSP response in the status_request TLS Certificate Status Request extension.

  • Internet Security Scanner
    Internet Security Scanner An extendable internet security scanner and analyser Kristian Helgesen Torkveen Thesis submitted for the degree of Master in Programming and System Architecture: Information Security 60 credits Department of Informatics Faculty of mathematics and natural sciences UNIVERSITY OF OSLO Spring 2021 Internet Security Scanner An extendable internet security scanner and analyser Kristian Helgesen Torkveen © 2021 Kristian Helgesen Torkveen Internet Security Scanner http://www.duo.uio.no/ Printed: Reprosentralen, University of Oslo Abstract The use of computers and networks in our daily lives is a fact at this point, and it is difficult to avoid interacting with computer systems and the internet. As more of our life depend on transmitting data over the internet, it’s important that we can facilitate this data transmission in a secure manner. In short, this means ensuring that developers and applications have access to use secure encrypted protocols for communication, and that these protocols are kept up to date and used in a proper manner. For the World Wide Web (WWW) and Hypertext Transfer Protocol (HTTP) the solution to facilitate this secure data transmission has become the Transport Layer Security (TLS) encrypted protocol, but the unencryp- ted HTTP protocol is still in use. Additionally, HTTP clients and servers implement several protocol specific security measures in the form of HTTP headers. This presents a challenge. Considering the decentralized nature of the world wide web and the various independent servers hosting web applications, how can we monitor the adoption and support of various versions of the TLS protocol and support for security features? In this thesis, I have created a scanner to monitor the use of TLS versions and various security features in the TLS and HTTP protocols.
