ActivClient 6.1 x86 is a computer security software package supplied by ActivIdentity. ActivClient verifies network user authorisation through the use of special tokens or access cards, according to ActivIdentity. This makes it more difficult for unknown intruders to gain entry into a computer network. The U.S. military and other government agencies use ActivClient so that employees can access high-security networks using government-issued identification cards.
ActivIdentity and associated software retailers distribute ActivClient 6.1 x86 via CD-ROM, according to CNET. Some military branches distribute the software through downloads within their computer networks, rather than using CDs. This allows authorised network users to download an updated version simply by clicking a link. ActivIdentity also supplies a free trial distribution of the software. It targets large organisations like government offices and corporations as potential customers. It sells access cards and USB tokens, as well.
ActivClient 6.1's predecessor is version 6.0. The software company released an updated edition more recently, version 6.2. Compatibility with different Windows operating systems varies by version, and ActivClient 6.1 x86 offers compatibility with Windows Vista. MilitaryCAC.com indicates that version 6.1 does not work under Windows Millennium or older versions of Windows, such as NT 4.0 or 98.
In combination with the necessary computer hardware, ActivClient 6.1 checks USB tokens and printed cards to ensure that the network administrator has authorised access to each person attempting to use the network. This proves especially important for screening remote access by portable computers outside of the office. The USB tokens look much the same as USB flash drives. CNET indicates that version 6.1 complies with a number of different security standards, such as ANSI X9.9 and RSA -- authentication and cryptography, respectively.
The "x86" designation refers to ActivClient's compatibility with Intel central processing units, such as the Pentium series. This reference stems from older Intel processors that people commonly referred to as "286" and "386" CPUs. It differentiates ActivClient 6.1 from software designed for other types of processors, such as those installed in older Macintosh computers. In addition, "x86" software typically runs on 32-bit computers, rather than 64-bit, x86 to 64 machines.
