    What Are the Different Types of SSL Certificates?
    August 7, 2013 by Dean Coclin DV Encryption EV Identity Phishing SSL/TLS
    Domain Validation (DV) A Domain Validated SSL certificate is issued after proof that the owner has the right to use their domain is established. This is typically done by the CA sending an email to the domain owner (as listed in a WHOIS database). Once the owner responds, the certificate is issued. Many CAs perform additional fraud checks to minimize issuance of a certificate to a domain which may be similar to a high value domain (i.

    All You Need to Know About the RC4 Encryption Scheme
    March 14, 2013 by Rick Andrews Attack CASC Encryption RC4 RSA SSL/TLS Vulnerability
    The latest published attacks target specific algorithms used within SSL/TLS. Those algorithms are used when a client connects to a server via SSL/TLS; they’re not used when a Certificate Authority signs a certificate. The attacks demonstrate potential weaknesses in the use of the algorithms. While interesting, the attacks don’t represent an immediate practical threat to users of SSL/TLS (including online banking, e-commerce, social networking, etc.). Such attacks require an attacker to run malicious software on a user’s computer which would connect to a particular web site and send the same message over and over again many times.

    The Importance of Revocation Checking Part 2: A Real World Example
    March 11, 2013 by Wayne Thayer Attack Code Signing CRL Encryption Identity Malware OCSP Revocation SSL/TLS
    Just last week, a new security incident related to certificate revocation checking made headlines. It was discovered that a legitimate website was hosting a malicious Java application that installed malware on the computers of people who visited the site. This comes after recent updates that introduced Security Level settings in Java, and then raised the default from Medium to High. At the high level, users are shown a warning before any unsigned Java code is executed.

    RSA Recap – Securing Your Site
    March 8, 2013 by Ben Wilson BEAST CASC Encryption Firefox Hash Function HSTS OpenSSL Policy RSA SSL/TLS TLS 1.1 TLS 1.2 Vulnerability
    At RSA last week a few of us participated in panel discussions that focused on SSL/TLS. During the panel that I moderated on Friday, one theme we addressed was secure server configuration. One of CASC’s goals is to help harden existing SSL/TLS implementations against vulnerabilities—because most SSL/TLS exploits arise from suboptimal website configurations. These vulnerabilities and attacks can be mitigated or even eliminated with proper server configuration and good website design.
