what is the root word of security

Also see "regression testing". DMZ's help to enable the layered security model in that they provide subnetwork segmentation based on security requirements or policy. Ping of DeathAn attack that sends an improperly large ICMP echo request packet (a "ping") with the intent of overflowing the input buffers of the destination machine and causing it to crash. Reverse ProxyReverse proxies take public HTTP requests and pass them to back-end webservers to send the content to it, so the proxy can then send the content to the end-user. Spanning PortConfigures the switch to behave like a hub for a specific port. IP AddressA computer's inter-network address that is assigned for use by the Internet Protocol and other protocols. Windows, for example, refers to daemons and System Agents and services. Network MappingTo compile an electronic inventory of the systems and the services on your network. and post-disaster recovery steps that will ensure the availability of Some common English vocabulary words that come from this word root include dict ionary, SyslogSyslog is the system logging facility for Unix systems. Cloud ComputingUtilization of remote servers in the data-center of a cloud provider to store, manage, and process your data instead of using local computer systems. War DialingWar dialing is a simple means of trying to identify modems in a telephone exchange that may be susceptible to compromise in an attempt to circumvent perimeter security. WebAnswer: * secuerity (mostly obsolete) EtymologyEdit Similar to Latin sine cura (without care, carefree), whi * secuerity (mostly obsolete) EtymologyEdit From Middle English It is defined in RFC 1203 (v3) and RFC 2060 (v4). Access Management AccessManagement is the kind of attack method involving an exhaustive procedure that tries all Webnoun. It deals with session and connection coordination. They can make filtering decisions based on IP addresses (source or destination), Ports (source or destination), protocols, and whether a session is established. Simple Network Management Protocol (SNMP)The protocol governing network management and the monitoring of network devices and their functions. Bastion HostA bastion host has been hardened in anticipation of vulnerabilities that have not been discovered yet. AuditingAuditing is the information gathering The client generates a one-time password by applying the MD4 cryptographic hash function multiple times to the user's secret key. The Log ClippingLog clipping is the selective removal of log entries from a system log to hide a compromise. HubA hub is a network device that operates by repeating data that it receives on one port to all the other ports. system is assigned a globally unique number, sometimes called an TLS is the successor to the Secure Sockets Layer. It also has active programs for encouraging and assisting industry and science to develop and use these standards. (This kind of protocol is referred to as connectionless.). An attacker assumes you're running vulnerable services that can be used to break into the machine. How do you find the root of a word? Integrity Star PropertyIn Integrity Star Property a user cannot read data of a lower integrity level then their own. It prevents hackers from seeing or stealing any information transferred, including personal or financial data. Post Office Protocol, Version 3 (POP3)An Internet Standard protocol by which a client workstation can dynamically access a mailbox on a server host to retrieve mail messages that the server has received and is holding for the client. ZombiesA zombie computer (often shortened as zombie) is a computer connected to the Internet that has been compromised by a hacker, a computer virus, or a trojan horse. Egress FilteringFiltering outbound traffic. It is issued by a certification authority. Rule Set Based Access Control (RSBAC)Rule Set Based Access Control targets actions based on rules for entities operating on objects. The system is typically configured to detect web sites which exploit vulnerabilities in the browser. SynchronizationSynchronization is the signal made up of a distinctive pattern of bits that network hardware looks for to signal that start of a frame. The uncertainties and anxieties that accompany this fast pace of change leaves them hankering after the imagined certitudes and securities of a more 'stable' past. HTTPSWhen used in the first part of a URL (the part that precedes the colon and specifies an access scheme or protocol), this term specifies the use of HTTP enhanced by a security mechanism, which is usually SSL. British Standard 7799A standard code of practice HopsA hop is each exchange with a gateway a packet takes on its way to the destination. It is also valuable as a single reference view of communication that furnishes everyone a common ground for education and discussion. Unlike TCP/IP, UDP/IP provides very few error recovery services, offering instead a direct way to send and receive datagrams over an IP network. It is comprised of a six step process: Preparation, Identification, Containment, Eradication, Recovery, and Lessons Learned. HeaderA header is the extra information in a packet that is needed for the protocol stack to process the packet. (This layer is not the application itself, although some applications may perform application layer functions.) As a result, data transmitted by one host is retransmitted to all other hosts on the hub. Race ConditionA race condition exploits the small window of time between a security control being applied and when the service is used. Fragment OffsetThe fragment offset field tells the sender where a particular fragment falls in relation to other fragments in the original larger packet. Symmetric cryptography is sometimes called "secret-key cryptography" (versus public-key cryptography) because the entities that share the key. IntegrityIntegrity is the need to ensure that information has not been changed accidentally or deliberately, and that it is accurate and complete. It is similar to phishing, but refers to fraudulent messages sent over SMS (text messaging) rather than email. ExposureA threat action whereby sensitive data is directly released to an unauthorized entity. Simple Integrity PropertyIn Simple Integrity Property a user cannot write data to a higher integrity level than their own. Assuming that an entry has been set up in the router table, the RARP server will return the IP address to the machine which can store it for future use. Measures of Effectiveness (MOE)Measures of Effectiveness is a probability model based on engineering concepts that allows one to approximate the impact a give action will have on an environment. Stateful InspectionAlso referred to as dynamic packet filtering. It is randomly generated and is different each time a connection is made. today's Internet, and was decommissioned in June 1990. Access MatrixAn Access Matrix uses rows to represent subjects and columns to represent objects with privileges listed in each cell. WindowingA windowing system is a system for sharing a computer's graphical display presentation resources among multiple applications at the same time. Identity Root. The routers must communicate using a routing protocol, of which there are many to choose from. Examples would be the Linefeed, which is ASCII character code 10 decimal, the Carriage Return, which is 13 decimal, or the bell sound, which is decimal 7. Non-Printable CharacterA character that doesn't have a corresponding character letter to its corresponding ASCII code. Depending on the size of the audit trail and the processing ability of the system, the review of audit data could result in the loss of a real-time analysis capability. FilterA filter is used to specify which packets will or will not be used. PolyinstantiationPolyinstantiation is the ability of a database to maintain multiple records with the same key. The signature is computed using rules and parameters such that the identity of the signer and the integrity of the signed data can be verified. Inetd (xinetd)Inetd (or Internet Daemon) is an application that controls smaller internet services like telnet, ftp, and POP. When the page is accessed by a web browser, the Common topologies include a bus, star, and ring. EncapsulationThe inclusion of one data structure within another structure so that the first data structure is hidden for the time being. A Unix program that takes an e-mail address as input and returns information about the user who owns that e-mail address. Layer 5: The session layerThis layer sets up, coordinates, and terminates conversations, exchanges, and dialogs between the applications at each end. IMAP is intended as a replacement for or extension to the Post Office Protocol (POP). Least PrivilegeLeast Privilege is the principle of allowing users or applications the least amount of permissions necessary to perform their intended function. CryptanalysisThe mathematical science that deals with analysis of a cryptographic system in order to gain knowledge needed to break or circumvent the protection that the system is designed to provide. Network traffic on other segments, and traffic on other means of communication (like phone lines) can't be monitored. Because the owner tends to be unaware, these computers are metaphorically compared to zombies. It uses inodes (pointers) and data blocks. Any network providing switched communications service. Usually expressed in bits per second. War DialerA computer program that automatically dials a series of telephone numbers to find lines connected to computer systems, and catalogs those numbers so that a cracker can try to break into the systems. S/KeyA security mechanism that uses a cryptographic hash function to generate a sequence of 64-bit, one-time passwords for remote user login. A filtering router does the same, but first decides whether the packet should be forwarded at all, according to some security policy. The term daemon is a Unix term, though many other operating systems provide support for daemons, though they're sometimes called other names. WebThe meaning of SECURE is free from danger. SOCKS uses sockets to represent and keep track of individual connections. The small program that lets the larger program communicate with a specific device such as a printer or scanner is often packaged as a DLL program (usually referred to as a DLL file). accessible to those who need to use it. The daemon program forwards the requests to other programs (or processes) as appropriate. DisassemblyThe process of taking a binary program and deriving the source code from it. Receive curated news, vulnerabilities, & security awareness tips, South Georgia and the South Sandwich Islands, This site is protected by reCAPTCHA and the Google, Do Not Sell/Share My Personal Information. and analysis of assets to ensure such things as policy compliance and Point-to-Point Protocol (PPP)A protocol for communication between two computers using a serial interface, typically a personal computer connected by phone line to a server. synonyms: security measures. cure si-kyur -kyr securer; securest Synonyms of secure 1 a : free from danger b : affording safety a secure hideaway c : trustworthy, dependable a secure foundation d : Poison ReverseSplit horizon with poisoned reverse (more simply, poison reverse) does include such routes in updates, but sets their metrics to infinity. Dynamic Link LibraryA collection of small programs, any of which can be called when needed by a larger program that is running in the computer. Token-Based DevicesA token-based device is triggered by the time of day, so every minute the password changes, requiring the user to have the token with them when they log in. Trojan HorseA computer program that appears to have a useful function, but also has a hidden and potentially malicious function that evades security mechanisms, sometimes by exploiting legitimate authorizations of a system entity that invokes the program. Threat VectorThe method a threat uses to get to the target. CachePronounced cash, a special high-speed storage mechanism. Backup tapes should be regularly tested to detect data corruption, malicious code and environmental damage. Disaster Recovery Plan (DRP)A Disaster Recovery Plan is the process of recovery of IT systems in the event of a disruption or disaster. Unlike static packet filtering, which examines a packet based on the information in its header, stateful inspection examines not just the header information but also the contents of the packet up through the application layer in order to determine more about the packet than just information about its source and destination. PayloadPayload is the actual application data a packet contains. Layer 4: The transport layerThis layer manages the end-to-end control (for example, determining whether all packets have arrived) and error-checking. In this attack the second fragment contains incorrect offset. A frame is usually transmitted serial bit by bit and contains a header field and a trailer field that "frame" the data. Crossover CableA crossover cable reverses the pairs of cables at the other end and can be used to connect devices directly together. PermutationPermutation keeps the same letters but changes the position within a text to scramble the message. communication channel to pass data through the channel in a given Gnutella acts as a server for sharing files while simultaneously acting as a client that searches for and downloads files from other users.
