LAN Manager

LAN Manager is the older file server product from Microsoft and IBM. The details of this aren't all that important except that backwards compatibility has introduced security holes in products 10 years later. LAN Manager authentication splits a password into two case-insensitive parts that are 7 letters each. Therefore, if your password was "RobertGraham.com", under LAN Manager it would be the same as "ROBERTG RAHAM.C". Whereas new products like Win98, WinNT, and SAMBA support newer/stronger authentication methods, the need for backwards compatibility often exposes the LAN Manager password, which can easily be cracked. [96]

latex

structured text formatting and typesetting [34]

latex2html

LaTeX to HTML translator. LaTeX2HTML is a conversion tool that that converts documents written in LaTeX to HTML format. In addition, it offers an easy migration path towards authoring complex hypermedia documents using familiar word-processing concepts. LaTeX2HTML replicates the basic structure of a LaTeX document as a set of interconnected HTML files which can be explored using automatically generated navigation panels. The cross-references, citations, footnotes, the table of contents and the lists of figures and tables, are also translated into hypertext links. Formatting information which has equivalent 'tags'' in HTML (lists, quotes, paragraph breaks, type styles, etc.) is also converted appropriately. The remaining heavily formatted items such as mathematical equations, pictures or tables are converted to images which are placed automatically at the correct positions in the final HTML document. LaTeX2HTML extends LaTeX by supporting arbitrary hypertext links and symbolic cross-references between evolving remote documents. It also allows the specification of conditional text and the inclusion of raw HTML commands. These hypermedia extensions to LaTeX are available as new commands and environments from within a LaTeX document. Pstoimg, the part of latex2html that produces bitmap images from the LaTeX source, can support both GIF and PNG format. Because of certain legal limitations on the use of the GIF image format, GIF support is disabled in this package. [3]

latex2rtf

LDAP

A directory service, LDAP (Lightweight Directory Access Protocol) is used by e-mail programs (Microsoft, Netscape, Eudora, etc.) to allow you to lookup a person's name in a corporate database and find their e-mail address, phone number, and other information that the corporate administrators decided to put in there. Key point: Most corporate LDAP servers have little or no authentication. Finding LDAP servers and downloading their contents is an important step in the reconnaissance phase of a hacking attack. Key point: While LDAP is in theory lightweight, in practice it is still fairly complicated. There are many implementation and deployment bugs that can be exploited in order to break into servers. [96]

LDAP

LDAP stands for Lightweight Directory Access Protocol. As the name suggests, it is a lightweight client-server protocol for accessing directory services, specifically X.500-based directory services. LDAP runs over TCP/IP or other connection oriented transfer services. LDAP is defined in RFC2251 "The Lightweight Directory Access Protocol (v3). A directory is similar to a database, but tends to contain more descriptive, attribute-based information. The information in a directory is generally read much more often than it is written. Directories are tuned to give quick-response to high-volume lookup or search operations. They may have the ability to replicate information widely in order to increase availability and reliability, while reducing response time. When directory information is replicated, temporary inconsistencies between the replicas may be OK, as long as they get in sync eventually. There are many different ways to provide a directory service. Different methods allow different kinds of information to be stored in the directory, place different requirements on how that information can be referenced, queried and updated, how it is protected from unauthorized access, etc. Some directory services are local, providing service to a restricted context (e.g., the finger service on a single machine). Other services are global, providing service to a much broader context. [24]

least privilege

A best-practices principle that states that users have only the minimum access they need, and no more. Example: System administrators typically have multiple accounts with different rights. For example, when I'm logged in as a normal user, I do not have rights to administrator my own machine. I must login as a separate account in order to administer the system, then log out as soon as I'm done. Most UNIX systems will use the hash/pound sign # at the command prompt in order to hint to the user that they have root access and should be careful. Key point: One of the leading causes of security breaches is authorization creep: as users change roles, they often get new privileges, but old privileges are rarely taken away. [96]

Leetnux

Leetnux is a Linux distribution specifically designed for Linux users who want maximum configuratibility. Therefore, the installation is quite hard, absolutely nothing is done "automagically" as in modern Linux distributions, but the user has total control over the installation. The idea behind Leetnux comes from Linux From Scratch, but a Leetnux system is not as "pure" as an LFS system, because a minimal pre-compiled system must be installed. Distribution development is not all that active. [33]
