SAINT (software)
SAINT (Security Administrator’s Integrated Network Tool) is computer software used for scanning computer networks for security vulnerabilities, and exploiting found vulnerabilities. SAINT Network Vulnerability Scanner The SAINT scanner screens every live system on a network for TCP and UDP services. For each service it finds running, it launches a set of probes designed to detect anything that could allow an attacker to gain unauthorized access, create a denial-of-service, or gain sensitive information about the network. SAINT provides support to the Security Content Automation Protocol (SCAP) specification as an Unauthenticated Vulnerability Scanner and Authenticated Vulnerability and Patch Scanner. SAINT is also an approved scanning vendor with the Payment Card Industry (PCI). The Four Steps of a SAINT Scan: * Step 1 – SAINT screens every live system on a network for TCP and UDP services. * Step 2 – For each service it finds running, it launches a set of probes designe ...

Vulnerability (computing)
Vulnerabilities are flaws in a computer system that weaken the overall security of the device/system. Vulnerabilities can be weaknesses in either the hardware itself, or the software that runs on the hardware. Vulnerabilities can be exploited by a threat actor, such as an attacker, to cross privilege boundaries (i.e. perform unauthorized actions) within a computer system. To exploit a vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness. In this frame, vulnerabilities are also known as the attack surface. Vulnerability management is a cyclical practice that varies in theory but contains common processes which include: discover all assets, prioritize assets, assess or perform a complete vulnerability scan, report on results, remediate vulnerabilities, verify remediation - repeat. This practice generally refers to software vulnerabilities in computing systems. Agile vulnerability management refers preventing attacks by ...

Transmission Control Protocol
The Transmission Control Protocol (TCP) is one of the main protocols of the Internet protocol suite. It originated in the initial network implementation in which it complemented the Internet Protocol (IP). Therefore, the entire suite is commonly referred to as TCP/IP. TCP provides reliable, ordered, and error-checked delivery of a stream of octets (bytes) between applications running on hosts communicating via an IP network. Major internet applications such as the World Wide Web, email, remote administration, and file transfer rely on TCP, which is part of the Transport Layer of the TCP/IP suite. SSL/TLS often runs on top of TCP. TCP is connection-oriented, and a connection between client and server is established before data can be sent. The server must be listening (passive open) for connection requests from clients before a connection is established. Three-way handshake (active open), retransmission, and error detection adds to reliability but lengthens latency. Applica ...

User Datagram Protocol
In computer networking, the User Datagram Protocol (UDP) is one of the core communication protocols of the Internet protocol suite used to send messages (transported as datagrams in packets) to other hosts on an Internet Protocol (IP) network. Within an IP network, UDP does not require prior communication to set up communication channels or data paths. UDP uses a simple connectionless communication model with a minimum of protocol mechanisms. UDP provides checksums for data integrity, and port numbers for addressing different functions at the source and destination of the datagram. It has no handshaking dialogues, and thus exposes the user's program to any unreliability of the underlying network; there is no guarantee of delivery, ordering, or duplicate protection. If error-correction facilities are needed at the network interface level, an application may instead use Transmission Control Protocol (TCP) or Stream Control Transmission Protocol (SCTP) which are designed for this ...

Denial-of-service Attack
In computing, a denial-of-service attack (DoS attack) is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to a network. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled. In a distributed denial-of-service attack (DDoS attack), the incoming traffic flooding the victim originates from many different sources. More sophisticated strategies are required to mitigate this type of attack, as simply attempting to block a single source is insufficient because there are multiple sources. A DoS or DDoS attack is analogous to a group of people crowding the entry door of a shop, making it hard for legitimate customers to enter, thus disrupting trade. Criminal perpetrators of DoS attacks oft ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Security Content Automation Protocol
The Security Content Automation Protocol (SCAP) is a method for using specific standards to enable automated vulnerability management, measurement, and policy compliance evaluation of systems deployed in an organization, including e.g., FISMA (Federal Information Security Management Act, 2002) compliance. The National Vulnerability Database (NVD) is the U.S. government content repository for SCAP. An example of an implementation of SCAP is OpenSCAP. Purpose To guard against security threats, organizations need to continuously monitor the computer systems and applications they have deployed, incorporate security upgrades to software and deploy updates to configurations. The Security Content Automation Protocol (SCAP), pronounced "ess-cap", but most commonly as "skap" comprises a number of open standards that are widely used to enumerate software flaws and configuration issues related to security. Applications which conduct security monitoring use the standards when measuring systems ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Payment Card Industry
The payment card industry (PCI) denotes the debit, credit, prepaid, e-purse, ATM, and POS cards and associated businesses. Overview The payment card industry consists of all the organizations which store, process and transmit cardholder data, most notably for debit cards and credit cards. The security standards are developed by the Payment Card Industry Security Standards Council which develops the Payment Card Industry Data Security Standards used throughout the industry. Individual card brands establish compliance requirements that are used by service providers and have their own compliance programs. Major card brands include American Express, Discover Financial Services, Japan Credit Bureau, Mastercard, RuPay, UnionPay and Visa. Most companies use member banks that connect and accept transactions from the card brands. Not all card brands use member banks, like American Express, these instead act as their own bank. , the United States uses a magnetic stripe on a card to p ...

Penetration Test
A penetration test, colloquially known as a pen test or ethical hacking, is an authorized simulated cyberattack on a computer system, performed to evaluate the security of the system; this is not to be confused with a vulnerability assessment. The test is performed to identify weaknesses (also referred to as vulnerabilities), including the potential for unauthorized parties to gain access to the system's features and data, as well as strengths, enabling a full risk assessment to be completed. The process typically identifies the target systems and a particular goal, then reviews available information and undertakes various means to attain that goal. A penetration test target may be a white box (about which background and system information are provided in advance to the tester) or a black box (about which only basic information—if any—other than the company name is provided). A gray box penetration test is a combination of the two (where limited knowledge of the target is sh ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Security Administrator Tool For Analyzing Networks
Security Administrator Tool for Analyzing Networks (SATAN) was a free software vulnerability scanner for analyzing networked computers. SATAN captured the attention of a broad technical audience, appearing in ''PC Magazine'' and drawing threats from the United States Department of Justice. It featured a web interface, complete with forms to enter targets, tables to display results, and context-sensitive tutorials that appeared when a vulnerability had been found. Naming For those offended by the name SATAN, the software contained a special command called ''repent'', which rearranged the letters in the program's acronym from "SATAN" to "SANTA". Description The tool was developed by Dan Farmer and Wietse Venema. Neil Gaiman drew thartworkfor the SATAN documentation. SATAN was designed to help systems administrators automate the process of testing their systems for known vulnerabilities that can be exploited via the network. This was particularly useful for networked systems with ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Dan Farmer
Dan Farmer (born April 5, 1962) is an American computer security researcher and programmer who was a pioneer in the development of vulnerability scanners for Unix operating systems and computer networks. Life and career Farmer developed his first software suite while he was a computer science student at Purdue University in 1989. Gene Spafford, one of his professors, helped him to start the project. The software, called the Computer Oracle and Password System (COPS), comprises several small, specialized vulnerability scanners designed to identify security weaknesses in one part of a Unix operating system. In 1995, Farmer and Wietse Venema (a Dutch programmer and physicist) developed a second vulnerability scanner called the Security Administrator Tool for Analyzing Networks (SATAN). Due to a misunderstanding of SATAN's capabilities, when it was first published, some network administrators and law enforcement personnel believed that hackers would use it to identify and break ...
