Honeypot (computing)
In computer terminology, a honeypot is a computer security mechanism set to detect, deflect, or, in some manner, counteract attempts at unauthorized use of information systems. Generally, a honeypot consists of data (for example, in a network site) that appears to be a legitimate part of the site which contains information or resources of value to attackers. It is actually isolated, monitored, and capable of blocking or analyzing the attackers. This is similar to police sting operations, colloquially known as "baiting" a suspect. Types Honeypots can be classified based on their deployment (use/action) and based on their level of involvement. Based on deployment, honeypots may be classified as: * production honeypots * research honeypots Production honeypots are easy to use, capture only limited information, and are used primarily by corporations. Production honeypots are placed inside the production network with other production servers by an organization to improve their overa ...

Computer Security
Computer security, cybersecurity (cyber security), or information technology security (IT security) is the protection of computer systems and networks from attack by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide. The field has become of significance due to the expanded reliance on computer systems, the Internet, and wireless network standards such as Bluetooth and Wi-Fi, and due to the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity is one of the most significant challenges of the contemporary world, due to both the complexity of information systems and the societies they support. Security is of especially high importance for systems that govern large-scale systems with far-reaching physical effects, such as power distribution, ...

Anti-spam
Various anti-spam techniques are used to prevent email spam (unsolicited bulk email). No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email (false positives) as opposed to not rejecting all spam email (false negatives) – and the associated costs in time, effort, and cost of wrongfully obstructing good mail. Anti-spam techniques can be broken into four broad categories: those that require actions by individuals, those that can be automated by email administrators, those that can be automated by email senders and those employed by researchers and law enforcement officials. End-user techniques There are a number of techniques that individuals can use to restrict the availability of their email addresses, with the goal of reducing their chance of receiving spam. Discretion Sharing an email address only among a limited group of correspondents is one way to limit the chance that the address will be "harveste ...

Indicator Of Compromise
Indicator of compromise (IoC) in computer forensics is an artifact observed on a network or in an operating system that, with high confidence, indicates a computer intrusion. Types of indication Typical IoCs are virus signatures and IP addresses, MD5 hashes of malware files, or URLs or domain names of botnet command and control servers. After IoCs have been identified via a process of incident response and computer forensics, they can be used for early detection of future attack attempts using intrusion detection systems and antivirus software. Automation There are initiatives to standardize the format of IoC descriptors for more efficient automated processing. Known indicators are usually exchanged within the industry, where the Traffic Light Protocol is being used. See also * AlienVault * Mandiant * Malware Malware (a portmanteau for ''malicious software'') is any software intentionally designed to cause disruption to a computer, server, client, or computer network, ...

Deception Toolkit
Deception or falsehood is an act or statement that misleads, hides the truth, or promotes a belief, concept, or idea that is not true. It is often done for personal gain or advantage. Deception can involve dissimulation, propaganda and sleight of hand as well as distraction, camouflage or concealment. There is also self-deception, as in bad faith. It can also be called, with varying subjective implications, beguilement, deceit, bluff, mystification, ruse, or subterfuge. Deception is a major relational transgressions, relational transgression that often leads to feelings of betrayal and distrust between relational partners. Deception violates relational Norm (sociology), rules and is considered to be a negative wikt:violation, violation of expectations. Most people expect friends, relational partners, and even strangers to be truthful most of the time. If people expected most conversations to be untruthful, talking and communicating with others would require distraction and misdir ...

Fred Cohen
Frederick B. Cohen (born 1956) is an American computer scientist and best known as the inventor of computer virus defense techniques. He gave the definition of "computer virus". Cohen is best known for his pioneering work on computer viruses, the invention of high integrity operating system mechanisms now in widespread use, and automation of protection management functions. In 1983, while a student at the University of Southern California's School of Engineering (currently the Viterbi School of Engineering), he wrote a program for a parasitic application that seized control of computer operations, one of the first computer viruses, in Leonard Adleman’s class. He wrote a short program, as an experiment, that could "infect" computers, make copies of itself, and spread from one machine to another. It was hidden inside a larger, legitimate program, which was loaded into a computer on a floppy disk. One of the few solid theoretical results in the study of computer viruses is Cohe ...

Cowrie (honeypot)
Cowrie is a medium interaction SSH and Telnet honeypot designed to log brute force attacks and shell interaction performed by an attacker. Cowrie also functions as an SSH and telnet proxy Proxy may refer to: * Proxy or agent (law), a substitute authorized to act for another entity or a document which authorizes the agent so to act * Proxy (climate), a measured variable used to infer the value of a variable of interest in climate re ... to observe attacker behavior to another system. Cowrie was developed from Kippo. Reception Cowrie has been referenced in published papers. The Book "''Hands-On Ethical Hacking and Network Defense''" includes Cowrie in a list of 5 commercial honeypots. Prior uses * Discussing a honeypot effort called the Project Heisenberg Cloud by Rapid7, Bob Rudis, the company's chief data scientist, told eWEEK, "There are custom Rapid7-developed low- and medium-interaction honeypots used within the framework, along with open-source ones, such as Cowri ...

SQL Injection
In computing, SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker). SQL injection must exploit a security vulnerability in an application's software, for example, when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and unexpectedly executed. SQL injection is mostly known as an attack vector for websites but can be used to attack any type of SQL database. SQL injection attacks allow attackers to spoof identity, tamper with existing data, cause repudiation issues such as voiding transactions or changing balances, allow the complete disclosure of all data on the system, destroy the data or make it otherwise unavailable, and become administrators of the database server. In a 2012 study, it was observed that the average w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spammers
This is a list of individuals and organizations noteworthy for engaging in bulk electronic spamming, either on their own behalf or on behalf of others. It is not a list of all spammers, only those whose actions have attracted substantial independent attention. * Nathan Blecharczyk, one of the founders of Airbnb, who paid his way through Harvard by providing spammers hosting services. * Shane Atkinson, who was named in an interview by ''The New Zealand Herald'' as the man behind an operation sending out 100 million emails per day in 2003, who claimed (and appeared) to honor unsubscribe requests, and who claimed to be giving up spamming shortly after the interview. His brother Lance was ordered to pay $2 million to U.S. authorities. * Serdar Argic (a.k.a. Zumabot), who disrupted Usenet by posting up to 100 messages per day on different newsgroups in an attempt to deny the Armenian genocide. * Canter & Siegel, a husband and wife who famously posted one of the first commercial Use ...

Project Honey Pot
Project Honey Pot is a web-based honeypot network operated by Unspam Technologies, Inc. It uses software embedded in web sites. It collects information about the IP addresses used when harvesting e-mail addresses in spam, bulk mailing, and other e-mail fraud. The project solicits the donation of unused MX entries from domain owners. In 2007, the Project began a number of new initiatives including a QuickLinks program that makes it easier for more people to participate, as well as a system to track comment spam. The Project has also launched a free new service called http:BL, which leverages the data to allow website administrators to keep malicious web robots off their sites. In addition to collecting information, which is made available on a "top 25" list at periodic intervals, the project organizers also help various law enforcement agencies combat private and commercial unsolicited bulk mailing offenses and, overall, work to reduce the amount of spam being sent and rec ...

Spamtrap
A spamtrap is a honeypot (computing), honeypot used to collect spam (electronic), spam. Spamtraps are usually e-mail addresses that are created not for communication, but rather to lure spam. In order to prevent legitimate email from being invited, the e-mail address will typically only be published in a location hidden from view such that an automated e-mail address harvester (used by spammers) can find the email address, but no sender would be encouraged to send messages to the email address for any legitimate purpose. Since no e-mail is solicited by the owner of this spamtrap e-mail address, any e-mail messages sent to this address are immediately considered unsolicited. The term is a Portmanteau, compound of the words "spam" and "trap", because a spam analyst will lay out spamtraps to catch spam in the same way that a fur trapper lays out traps to catch wild animals. The provenance of this term is unknown, but several competing anti-spam organizations claim trademark over it. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
