Examples: NIPRNet, SIPRNet. RBAC (Role Base Access Control) controls access through the use of job labels, which have been assigned the permissions and privilege needed to accomplish the related job tasks. An easter egg is undocumented, non malicious, accessible to anyone, and entertaining. Security information and event management (SIEM). XML is short for eXtensible Markup Language. Session hijacking is also known as cookie hijacking. An analog is a transmission signal that varies in signal strength (amplitude) or frequency (time). Penetration testing is also called pen testing. a recipe) for using cryptographic concepts in support of secure communications, storage and job tasks. An unauthorized person gains access to a network and stays there undetected for a long period of time, with an intention to steal data rather than to cause direct damage to the network. 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. If your WiFi network is not secure, malicious hackers will often use a GPS system to make maps of exploitable zones so they can be used at a later time or passed on to others. A share is any resource that has been made public on a system or network, such as a directory or printer. A subnet mask is used to determine the number of bits that are used for the subnet and host portions of the address. A restore or restoration process may involve formatting the main storage device before re-installing the operating system and applications as well as copying data from backups onto the reconstituted system. Examples would be the Linefeed, which is ASCII character code 1 decimal, the Carriage Return, which is 13 decimal, or the bell sound, which is decimal 7. A steady state is a characteristic of a condition, such as value, rate, periodicity, or amplitude, exhibiting only negligible change over an arbitrarily long period of time. Data assets can also be a service that may be provided to access data from an application. The false website will often look and operate similarly to the legitimate site and focus on having the victim provide their logon credentials and potentially other personal identity information such as answers to their security questions, an account number, their social security number, mailing address, email address and/or phone number. An exercise key is cryptographic key material used exclusively to safeguard communications transmitted over-the-air during military or organized civil training exercises. A security policy is usually comprised of standards, policies (or SOPs – Standard Operating Procedures) and guidelines. the XOR result is a non-zero value), then something about the data changed during the event. Data loss occurs when a storage device is lost or stolen. EPP stands for endpoint protection platform. In Simple Integrity Property, a user cannot write data to a higher integrity level than their own. Two-step is not as secure as two-factor because the system provides one of the factors to the user at the time of logon rather than requiring that the user provide both. A honeypot may contain false data in order to trick attackers into spending considerable time and effort attacking and exploiting the false system. An IPS is considered a more active security tool as it attempts to proactively respond to potential threats. The connections between the vertices form a baseball diamond shape. Access type is used to specify attributes. Critical Infrastructure is the fundamental system of an organization that is important for its survival. The aberration can be in amplitude, phase timing, or the width of the signal pulse. This is different than cryptography, which hides the meaning of a message but does not hide the message itself. In computer security, mandatory access control (MAC) refers to a type of access control by which the operating system constrains the ability of a subject or initiator to access or generally perform some sort of operation on an object or target. Token-based Access Control is an authentication method that offers additional security. phishing — A social engineering attack that attempts to collect information from victims. (See botnet.). Phishing attacks can take place over e-mail, text messages, through social networks or via smart phone apps. data breach — The occurrence of disclosure of confidential information, access to confidential information, destruction of data assets or abusive use of a private IT environment. The sum of the mean times in each hop indicates the total time spent to establish the connection. Information is stored on, and can be retrieved form the cloud or internet. A device that converts digital data to human-readable text on physical paper. Mass Mailer is a threat that self-replicates by sending itself through email. We have A compromise is the violation of the company's system security policy by an attacker. An embedded cryptosystem is a system performing or controlling a function as an integral element of a larger system or subsystem. A router is a hardware device that transfers data packets to the appropriate networks. Medical services, retailers and public entities experienced the most breaches, wit… A drive-by download can install tracking tools, remote access backdoors, botnet agents, keystroke loggers or other forms of malicious utilities. A honeymonkey is an automated program that imitates a human user to detect and identify websites which exploit vulnerabilities on the Internet. A secret seed is a secret value used to initialize a pseudorandom number generator. An intranet is a organisation's private network. A reverse proxy is a device or service that is placed between a client and a server in a network. watch for programs that have behaviors that are different from the normal baseline of behavior of the system), and heuristic detection (i.e. It also provides complete freedom as to the software or custom code run on the virtual machines. See also Denial of Service Attack. Stealthing is a term that refers to approaches used by malicious code to conceal its presence on the infected system. In network security, endpoint security refers to a methodology of protecting the corporate network when accessed via remote devices such as laptops and mobile devices. The reference model defines seven layers of functions that take place at each end of a communication. Viruses often perform some type of harmful activity on infected host computers, such as acquisition of hard disk space or central processing unit (CPU) time, accessing private information (e.g., credit card numbers), corrupting data, or displaying messages on a computer’s screen. OPSEC (operations security) is a process by which we protect unclassified information that can hurt us. Most forms of cloud computing are considered public cloud as they are provided by a third party. In accounting, the assets of an organization include all the equity a business has (what the business owns), minus its liabilties (what the business owes). botnet — A collection of innocent computers which have been compromised by malicious code in order to run a remote control agent granting an attacker the ability to remotely take advantage of the system's resources in order to perform illicit or criminal actions. A netmask isused to divide an IP address into subnets and specify the network's available hosts. Sometimes referred to as a security level. NIST's activities are organized into laboratory programs that include Nanoscale Science and Technology, Engineering, Information Technology, Neutron Research, Material Measurement, and Physical Measurement. Dividing an Ethernet into multiple segments is one of the most common ways of increasing available bandwidth on the LAN. It enforces the security policy and provides required capabilities. restore — The process of returning a system back to a state of normalcy. A hacker may be ethical and authorized (the original definition) or may be malicious and unauthorized (the altered but current use of the term). Simple Network Management Protocol (SNMP). Distributed denial of service is a type of DOS attack where multiple compromised systems, which are often infected with a Trojan, are used to target a single system causing a Denial of Service (DoS) attack. 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 switch allows for many conversations to occur simultaneously. A decryption key is a piece of code that is required to decipher or convert encrypted text or information into plain text or information. of vacancies : 1 Employment type : Contract (Renewable based on performance) 1. The TRU ITS Information Security Team supports the University's mission by evaluating information security vulnerabilities and implementing technologies, procedures, and guidelines to ensure that appropriate levels of confidentiality, integrity, and availability of … hacker — A person who has knowledge and skill in analyzing program code or a computer system, modifying its functions or operations and altering its abilities and capabilities. zombie — A term related to the malicious concept of a botnet. TCP guarantees delivery of data and also guarantees that packets will be delivered in the same order in which they were sent. Multiplexing is a technique by which multiple data streams are combined into one signal over a shared medium. A digital certificate is based on the x.509 v3 standard. Spyware can track a user’s internet surfing habits for advertising habits, scan computers to create pop up ads, and change one’s homepage to redirect to pre chosen websites. Ciphertext is produced by a symmetric encryption algorithm when a data set is transformed by the encryption process using a selected key (i.e. The additional step could be receiving a text message with a code, then typing that code back into the website for confirmation. A gray hat is a white hat/ black hat hybrid. However, they may use illegal means to gain access to the net work to expose the security weakness. A hash value is the result of applying a cryptographic hash function to data (e.g., a message). A sniffer is a tool that monitors network traffic that is received in a network interface.
