Related QuestionsWhat are some typical signatures of well-known programs?
FAQ: Firewall Forensics (What am I seeing?)The program "traceroute" is based upon a very intelligent hack by Van Jacobson (also famous for other nifty kludges). Every IP packet has a time-to-live (TTL) field that indicates how many hops the packet can travel before being dropped. This field is needed because routers sometimes get misconfigured and will forward packets in a continuous: i.e. Alice forwards the packet to Bob who forwards it to Charlene who mistakenly forwards it back to Alice.
Related QuestionsAre there any known weaknesses in Kerberos?
Kerberos FAQs - WikiFAQ - Answers to Frequently Asked Questi...Kerberos makes no provisions for host security; it assumes that it is running on trusted hosts with an untrusted network. If your host security is compromised, then Kerberos is compromised as well. However, the degree to which Kerberos is compromised depends on the host that is compromised. If an attacker breaks into a multi-user machine and steals all of the tickets stored on that machine, he can impersonate the users who have tickets stored on that machine but only until those tickets expire.
Related QuestionsHow do the pdf-revisions correlate with the signatures?
Neue Seite 1A major characteristic of the PDF-format is the concept of document revisions. If a signed document is changed later, the signature does not become invalid, like in other formats. Instead, a new revision is created, and the signature remains valid with the hint "document was changed". This behaviour can irritate the users easily, because it is not obvious what has been changed. Older versions of Acrobat are even displaying the signatures in changed documents as valid without the hint.

Certificates are based on the ITU-T X.509 recommendation.
