Nokia IPSO
Check Point IPSO is the operating system for the 'Check Point firewall' appliance and other security devices, based on FreeBSD, with numerous hardening features applied. The IP in IPSO refers to Ipsilon Networks, a company specialising in IP switching acquired by Nokia in 1997. In 2009, Check Point acquired the Nokia security appliance business, including IPSO, from Nokia. Variations IPSO, now at version 6.2, is a fork of FreeBSD 6. There were two other systems, called IPSO-SX and IPSO-LX, that were Linux-based: * IPSO SX was Nokia's first release of a Linux-based IPSO, and was deployed in 2002 on the now-defunct Message Protector, and briefly thereafter on a short-lived appliance version of the "Nokia Access Mobilizer", acquired from Eizel. It had a partitioning scheme somewhat reminiscent of IPSO SB, a LILO configuration and boot manager also somewhat inspired by IPSO SB, and a software package installer that made RPM packaging look more familiar to a Nokia IPSO administ ...

Operating System
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer from cellular phones and video game consoles to web servers and supercomputers. The dominant general-purpose personal computer operating system is Microsoft Windows with a market share of around 74.99%. macOS by Apple Inc. is in second place (14.84%), and ...

Cluster (computing)
A computer cluster is a set of computers that work together so that they can be viewed as a single system. Unlike grid computers, computer clusters have each node set to perform the same task, controlled and scheduled by software. The components of a cluster are usually connected to each other through fast local area networks, with each node (computer used as a server) running its own instance of an operating system. In most circumstances, all of the nodes use the same hardware and the same operating system, although in some setups (e.g. using Open Source Cluster Application Resources (OSCAR)), different operating systems can be used on each computer, or different hardware. Clusters are usually deployed to improve performance and availability over that of a single computer, while typically being much more cost-effective than single computers of comparable speed or availability. Computer clusters emerged as a result of convergence of a number of computing trends including th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Framing (World Wide Web)
In the context of a web browser, a frame is a part of a web page or browser window which displays content independent of its container, with the ability to load content independently. The HTML or media elements shown in a frame may come from a different web site as the other elements of content on display, although this practice, known as framing, is today often regarded as a violation of same-origin policy. In HTML, a frameset is a group of named frames to which web pages and media can be directed; an iframe provides for a frame to be placed inside the body of a document. Since the early 2000s, the use of framesets has been considered obsolete due to usability and accessibility concerns, and the feature has been removed from the HTML5 standard. Tags and attributes The frames in HTML are created using the tag pair. The tag is a container tag for all other tags that are used to create frames. The tag replaces the tag in frameset documents.The tag defines how to divide t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

FireWall-1
VPN-1 is a firewall and VPN product developed by Check Point Software Technologies Ltd. VPN-1 is a stateful firewall which also filters traffic by inspecting the application layer. It was the first commercially available software firewall to use stateful inspection. Later (1997), Check Point registered U.S. Patent # 5,606,668 on their security technology that, among other features, included stateful inspection. VPN-1 functionality is currently bundled within all the Check Point's perimeter security products. The product, previously known as FireWall-1, is now sold as an integrated firewall and VPN solution. Platforms The VPN-1 software is installed on a separate operating system, which provides the protocol stack, file system, process scheduling and other features needed by the product. This is different from most other commercial firewall products like Cisco PIX and Juniper firewalls where the firewall software is part of a proprietary operating system. Although traditio ...

Asynchronous Transfer Mode
Asynchronous Transfer Mode (ATM) is a telecommunications standard defined by American National Standards Institute (ANSI) and ITU-T (formerly CCITT) for digital transmission of multiple types of traffic. ATM was developed to meet the needs of the Broadband Integrated Services Digital Network as defined in the late 1980s, and designed to integrate telecommunication networks. It can handle both traditional high-throughput data traffic and real-time, low-latency content such as telephony (voice) and video.ATM Forum, The User Network Interface (UNI), v. 3.1, , Prentice Hall PTR, 1995, page 2. ATM provides functionality that uses features of circuit switching and packet switching networks by using asynchronous time-division multiplexing.McDysan (1999), p. 287. In the OSI reference model data link layer (layer 2), the basic transfer units are called '' frames''. In ATM these frames are of a fixed length (53 octets) called ''cells''. This differs from approaches such as Internet Pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disk Partitioning
Disk partitioning or disk slicing is the creation of one or more regions on secondary storage, so that each region can be managed separately. These regions are called partitions. It is typically the first step of preparing a newly installed disk, before any file system is created. The disk stores the information about the partitions' locations and sizes in an area known as the partition table that the operating system reads before any other part of the disk. Each partition then appears to the operating system as a distinct "logical" disk that uses part of the actual disk. System administrators use a program called a partition editor to create, resize, delete, and manipulate the partitions. Partitioning allows the use of different filesystems to be installed for different kinds of files. Separating user data from system data can prevent the system partition from becoming full and rendering the system unusable. Partitioning can also make backing up easier. A disadvantage is that ...

Router (computing)
A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions between networks and on the global Internet. Data sent through a network, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node. A router is connected to two or more data lines from different IP networks. When a data packet comes in on one of the lines, the router reads the network address information in the packet header to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey. The most familiar type of IP routers are home and small office routers that simply forward IP packets between the home computers and the Internet. More sophisticated routers, ...

IPv6
Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), the communication protocol, communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion, and is intended to replace IPv4. In December 1998, IPv6 became a Draft Standard for the IETF, which subsequently ratified it as an Internet Standard on 14 July 2017. Devices on the Internet are assigned a unique IP address for identification and location definition. With the rapid growth of the Internet after commercialization in the 1990s, it became evident that far more addresses would be needed to connect devices than the IPv4 address space had available. By 1998, the IETF had formalized the successor protocol. IPv6 uses 128-bit addresses, theoretically allowing 2128, or approximatel ...
