Example text

In this particular context, no particular action needs to be taken, except to alert the user to pay attention to this type of error message. The second technique for compromising an SSL connection is based on the man in the middle concept. To do this, the attacker must first: – configure his machine to act as a proxy for all types of traffic, except HTTP and HTTPS; – implement an ARP spoof against the victim’s workstation, in order to make believe that the hacker’s machine is now the gateway. In this way, all of the victim’s PC traffic will be directed towards the hacker; – install software such as ssltrip, in order to redirect all HTTPS traffic to HTTP, giving the victim the illusion that his connection is via SSL, despite this not being the case.

In truth, two problems currently exist: – the exponential growth of the number of certificates from CAs included in browsers (1,482, according to a study by the Electronic Frontier Foundation), which can challenge the legitimacy of all of these certification authorities; – the quality of work in processing applications for certification is flawed in some cases: - 6,000 valid certificates have been issued for hostnames such as “localhost”, according to the EFF; - certification of the name “Microsoft Corporation” for a person who has nothing to do with Microsoft, and which gave rise to the security bulletin MS01-017.

To summarize, the main differences between SSL v2 and v3 are as follows: – the ability to authenticate the client using certificates with V3; Threats and Attacks 35 – the use of the compression function required by v3, allowing the structure of the original text to be “scrambled” and making it more difficult to launch cryptographic attacks based on limited knowledge of the structure of the initial plain text messages; – truncation attacks are no longer possible in version 3. In version 2, an attacker could forge TCP messages to end an SSL session, without the recipient (client or server) knowing that this decision was made by a hacker.
