  • What to Look for in Secure Sockets Layer

    Any website that collects or transmits sensitive information must be protected by Secure Socket Layer encryption. SSL and its successor, Transport Security Layer (TLS), are security protocols used to create an encrypted link between a server and a client on the Internet, typically between a Web server and a Web browser. Failing to employ SSL/TLS can result in lawsuits and possible penalties should visitor data be compromised. Likewise, reputation damage can greatly impact future business.

    This Buyer's Guide explains SSL and TLS technology in general and the types of SSL certificates available today. It also reviews features to consider and offers insights on how to determine the best SSL for a particular enterprise.

    Infosec pros and others who study this guide will come away with a more thorough understanding of SSL/TLS and be able to better identify what their company needs when in the market for SSL.

  • Will TLS 1.3 solve the problems of certificate authorities?

    Transport Layer Security (TLS) and Secure Sockets Layer (SSL) cryptographic protocols have long been the cornerstone of Web application security, and the whole process finds its root (quite literally) in a system of signed certificates. The trouble is this security system has turned into a vulnerability. Too often an enterprise possesses a hodgepodge of signed certificates from various Certificate Authorities (CAs) that are thrown into the directories of protected services, and then often forgotten until they expire. Worse yet, recently hackers have managed to create fake certificates. CAs -- once a seemingly effective answer to ensuring Web security -- are now providing an attack surface for hackers to take advantage of.

    This technical guide surveys the CA landscape, opening with a field report on the latest CA security issue, the problem of fake certificates. To help explain the nature of this threat, our second chapter delves into the certificate system, current problems with it, and what enterprise IT staff can do. This guide’s closing chapter examines industry efforts to cope with the threat: TLS 1.3. Through this guide, IT professionals, and especially those concerned with network security, will learn the latest about TLS/SSL security. Continue Reading
