If the latter, the zombie is the tool that is performing malicious actions such as DoS flooding, SPAM transmission, eavesdropping on VoIP calls or falsifying DNS resolutions as one member of a botnet. SET ensures that all parties (customers, merchant, and bank) are authenticated using digital signatures, encryption protects the message and provides integrity, and provides end-to-end security for credit card transactions online. STIX is a language for having a standardized communication for the representation of cyberthreat information. YARA is a tool aimed at (but not limited to) helping malware researchers to identify and classify malware samples. A sniffer is a tool that monitors network traffic that is received in a network interface. HTTPS (also called HTTP over TLS, HTTP over SSL, and HTTP Secure) is an Internet protocol used for secure communication over a computer network. A report by RiskBased Securityrevealed that a shocking 7.9 billion records have been exposed by data breaches in the first nine months of 2019 alone. A windowing system uses a window manager to keep track of where each window is located on the display screen and its size and status. A set of forms) is used to customize your next visit to the same web server. Behavioral monitoring can include the tracking of trends, setting of thresholds and defining responses. A patch is a piece of software security update designed to update a computer program or its supporting data, to fix or improve it. Telnet is a TCP-based, application-layer, Internet Standard protocol and an essential TCP/IP protocol for accessing remote computers. It focuses on defining customer needs, security protection requirements, and required functionality early in the systems development life cycle, documenting requirements, and then proceeding with design, synthesis, and system validation while considering the complete problem. Race conditions can occur in electronics systems, especially logic circuits, and in computer software, especially multithreaded or distributed programs. An ad hoc network does not rely on a base station to coordinate different points, rather the individual base nodes forward packets to and from each other. When the challenge is solved with a private key operation, access is then allowed. It is a way of specifying the location of publicly available information on the Internet. Threat Intelligence Information about specific impending attacks against the organization and is initially consumed by higher level security. OSI defines seven layers of functions that take place at each end of a communication. Triple wrapped describes any data that has been signed with a digital signature, encrypted, and then signed again is called triple-wrapped. A zombie is a malware program that can be used by a black hat cracker to remotely take control of a system, which is then used as a zombie drone for further attacks (e.g. It is one of the seven layers in both of the standard models of computer networking: the Internet Protocol Suite (TCP/IP) and the Open Systems Interconnection model (OSI model). A common strategy is based on the 3-2-1 rule: you should have three copies of your data - the original and 2 backups; you should use 2 different types of media (such as a physical media (such as a hard drive or tape) and a cloud storage solution); and do not store the three copies of data in 1 plane (i.e. CVE (Common Vulnerabilities and Exposures) — An online database of attacks, exploits and compromises operated by the MITRE organization for the benefit of the public. Resource Starvation is a condition where a computer process cannot be supported by available computer resources. (Also known as cryptogram.). "A proximity sensor is a non-contact sensor with the ability to detect the presence of a target within a specified range. Two-factor authentication is a security measure, to obtain evidence of identity by two independent means, such as knowing a password and successfully completing a smartcard transaction. A honeypot may also be able to discover new attacks or the identity of the attackers. GNU is an operating system and an extensive collection of computer software. The MD5 message-digest algorithm is the most widely used cryptographic hash function producing a 128-bit (16-byte) hash value, typically expressed in text format as a 32 digit hexadecimal number. Unauthorized Access is when a person gains logical or physical access without permission to a network, system, application, data, or other resource. A backup is the only insurance against data loss.
