It defines the objectives and constraints for the security program. A multi-homed host is physically connected to multiple data links that can be on the same or different networks. External security testing is security testing conducted from outside the organization's security perimeter. When a password has n-bits of guessing entropy then an attacker has as much difficulty guessing the average password as in guessing an n-bit random quantity. Access rights are permissions that are granted to a user, or an application, to view, modify or delete files in the network. This can slow down the victim's computer to the point where it becomes impossible to work on. credit card details, passwords) for unauthorized use. Massachusetts Institute of Technology (MIT) developed the Kerberos to protect network services provided by the Project Athena. Control network of an enterprise is typically connected to equipment that controls physical processes and that is time or safety critical. Generally, a data breach results in internal data being made accessible to external entities without authorization. The netmask screen out the network part of an IP address so that only the host computer part of the address remains.

However, they may use illegal means to gain access to the net work to expose the security weakness. Membership . A form of filtering that blocks only websites specified as harmful. It is the discretion of owner to grant permit or restrict users from accessing the resources completely or partially. Tcpdump works on most Unix-like operating systems. However, spyware can also be operated by attackers using the data gathering tool to steal an identity or learn enough about a victim to harm them in other ways. (Also known as penetration testing or ethical hacking.). This reduces the load of the system. A drive-by download can install tracking tools, remote access backdoors, botnet agents, keystroke loggers or other forms of malicious utilities. It is a network node that is assigned a network layer host address. Risk is the probability of that a vulnerability in a system or network will be exploited for attack, both intentionally or accidentlly. Manipulated variable is a process that is intended to regulate some condition, a quantity or a condition that the control alters to initiate a change in the value of the regulated condition. The Cybersecurity Community of Practice (CoP) intends to inform, engage and influence in relation to matters that may impact the end-user experience of health care software in an increasingly Octets are generally displayed using a variety of representations, for example in the hexadecimal, decimal, or octal number systems. The main functions of intrusion prevention systems are to identify malicious activity, log information about this activity, attempt to block/stop it, and report it. The distinction of DDOS from DOS is that the attack traffic may originate from numerous sources or is reflected or bounced off of numerous intermediary systems. Electronic commerce or ecommerce is any type of business, or commercial transaction, that involves the transfer of information across the Internet. XML is a specification developed by W3C starting with the recommendation on February 1 , 1998. Ethernet is the most popular Local Area Network (LAN) technology that specifies cabling and signalling system for home or organization networks. Proprietary information is information that is unique and will affect a company's ability to compete, such as customer lists, technical data, product costs, and trade secrets. (See phishing.). It uses a special three-byte frame called a token that travels around a logical ring of workstations or servers. Ciphertext is produced by a symmetric encryption algorithm when a data set is transformed by the encryption process using a selected key (i.e. This is an advanced form of security assessment that should only be used by environments with a mature security infrastructure. A hyperlink is a link from a hypertext file or document to another location or file, typically activated by clicking on a highlighted word or image on the screen. A security relevant change is any change to a system’s configuration, environment, information content, functionality, or users which has the potential to change the risk imposed upon its continued operations. A spear phishing message is often an e-mail although there are also text message and VoIP spear phishing attacks as well, which looks exactly like a legitimate communication from a trusted entity. XMT is the method of sending data to an alternate computer or device. MDM (master data management) is a comprehensive method of enabling an enterprise to link all of its critical data to one file, called a master file, that provides a common point of reference. Natural disasters are any act of God or natural event caused by environmental factors. payment card skimmers — A malicious device used to read the contents of an ATM, debit or credit card when inserted into a POS (Point of Sale) payment system. Each device with a remote connecting to the network creates a potential entry point for security threats. HTTP is the underlying protocol used by the World Wide Web (WWW). Asymmetric Key Cryptography, also known as Public key cryptography, is an cryptographic system that uses pairs of keys: public keys which may be disseminated widely, and private keys which are known only to the owner. In this approach, the rectangular window, involves simply truncating the dataset before and after the window, while not modifying the contents of the window at all. ( Learn more ) Data Backup is a copy of computer data taken and stored elsewhere to be used later in the case of hardware malfunction or data loss due to cyber-attack. DAC (Discretionary Access Control) manages access using ACL (Access Control Lists) on each resource object where users are listed along with the permissions or privileges granted or denied them. A scatternet is a type of ad hoc computer network consisting of two or more piconets. It is a violation of availability. An operating system (OS) is a software that manages computer hardware and software resources to support the computer's basic functions. zombie — A term related to the malicious concept of a botnet. Remote diagnostics refers to diagnostics activities conducted by individuals communicating externally to an information system security perimeter. Software is any computer instructions, data, or programs that can be stored electronically and executed by a computer hardware. The Reverse Address Resolution Protocol (RARP) is an obsolete computer networking protocol used by a client computer to request its Internet Protocol (IPv4) address from a computer network, when all it has available is its link layer or hardware address, such as a MAC address. A cold site is a backup site that can became operational fairly quickly, usually in one or two days. Terms of Reference – Cyber Risk Investigation Working Party 1. data-at-rest) or an occurrence of transmission (i.e. A zero day vulnerability refers to a hole in software that is unknown to the vendor. The chain of evidence goes in the following order: collection and identification; analysis; storage; preservation; presentation in court; return to owner. A Security Control Assessor is the individual, group, or organization responsible for conducting a security control assessment. Hackers can range from professionals who are skilled programmers to those who have little to no knowledge of the specifics of a system or exploit but who can follow directions; in this instance, they are called script kiddies. The purpose is to move data between computers that use a protocol not supported by the network connecting them. security experts, is today transforming into a much broader domain, referred to as “cybersecurity.” As it is an emergent issue, one in which there remains disagreement over basic terms, the ESCWG has sought to bring some clarity and commonality to this issue through creation of this reference curriculum. It is a way to store information (in variables) to be used across multiple pages. It is applied to an entity class, mapped superclass or embeddable class. Security strength is a measure of the computational complexity associated with recovering certain secret and/or security-critical information concerning a given cryptographic algorithm from known data (e.g. Least Privilege is the security principle of allowing users the least amount of permissions necessary to perform their intended function.
