Spam, security
SPAM refers to sending unwanted messages in large quantities to many recipients. There are several types of spam, including email spam, social networking spam, blog spam, SMS spam, forum spam, video sharing site spam, and online game messaging spam. Spam is commonly used to advertise dubious products, schemes, or services. To protect from spam, maintain separate public and private email addresses, do not respond to or unsubscribe from spam messages, use strong anti-spam software, update browsers and security patches, and avoid posting email addresses on suspicious websites.

PHISHING DETECTION
This document summarizes literature on detecting phishing attacks. It begins with an introduction defining phishing and explaining the broad scope of the problem. It then outlines the document's objectives and various definitions related to phishing. Several techniques for mitigating, detecting, and evaluating phishing attacks are discussed, including user training, software classification, offensive defense, correction approaches, and prevention. Evaluation metrics and examples of detection methods like passive/active warnings, visual similarity analysis, and blacklists are also summarized. The conclusion recommends education as the best defense and outlines common characteristics of phishing attacks.
Spoofing Techniques
Spoofing involves falsifying data to masquerade as another user or system. There are several types of spoofing attacks:
IP spoofing involves altering packet source IP addresses to hide the identity of the actual source. URL and referrer spoofing tricks users into thinking they are visiting legitimate sites when they are actually being directed to fake sites controlled by attackers. Caller ID spoofing allows callers to hide their real numbers. Email address spoofing modifies email headers to make emails appear to be from someone other than the actual sender. Spoofing techniques are commonly used by hackers and spammers to conceal their identities and gain illegitimate access.
Web Security Attacks
Web application security is the process of securing confidential data stored online from unauthorized access and modification. This is accomplished by enforcing stringent policy measures.
A web threat is any threat that uses the World Wide Web to facilitate cybercrime. Web threats use multiple types of malware and fraud, all of which utilize HTTP or HTTPS protocols, but may also employ other protocols and components, such as links in email or IM, or malware attachments or on servers that access the Web.

Phishing attacks ppt
This document discusses phishing, which is a form of online fraud that aims to steal users' sensitive information such as usernames, passwords, and credit card details. It does this through deceptive messages that appear to come from legitimate organizations but actually lead to fake websites or download malware. The document provides information on how phishing works, techniques used to detect and prevent it, and tips for users to avoid falling victim to phishing scams.
Man in The Middle Attack
A man-in-the-middle (MITM) attack intercepts communications between two parties by relaying and controlling messages between them. The attacker eavesdrops and potentially modifies the communication by replacing the keys for their own. This allows them to intercept sensitive transmissions like passwords or financial transactions. A MITM works by spoofing the MAC address of the target to intercept and manipulate traffic between the target and other devices on the network, such as a router. Encrypted connections and careful certificate verification can help prevent MITM attacks.
final-spam-e-mail-detection-180125111231.pptx
This document discusses using machine learning for email spam filtering. It proposes using a naïve Bayes classifier to classify emails as spam or not spam based on features like word frequencies. The document outlines preprocessing steps like tokenization, lemmatization and stop word removal. It discusses testing the classifier on labeled datasets and achieving 99.18% accuracy at identifying spam emails. The conclusion states that while the classifier works well on limited data, it may struggle with very large volumes of emails.
Phishing Attacks
Phishing attacks involve hackers sending fraudulent emails trying to steal users' login credentials and financial information. These attacks are sometimes combined with viruses or worms to harvest more email addresses to target. Technological solutions for detecting and preventing phishing include email scanning, server authentication, secure web authentication, digitally signed emails, and desktop/mail gateway filtering. While individual awareness is important, financial institutions and companies must also adopt technological countermeasures and policies to curb phishing attacks and losses from stolen data.

MINIMIZING THE TIME OF SPAM MAIL DETECTION BY RELOCATING FILTERING SYSTEM TO ...
Unsolicited Bulk Emails (also known as Spam) are undesirable emails sent to massive number of users. Spam emails consume the network resources and cause lots of security uncertainties. As we studied, the location where the spam filter operates in is an important parameter to preserve network resources. Although there are many different methods to block spam emails, most of program developers only intend to block spam emails from being delivered to their clients. In this paper, we will introduce a new and efficient approach to prevent spam emails from being transferred. The result shows that if we focus on developing a filtering method for spams emails in the sender mail server rather than the receiver mail server, we can detect the spam emails in the shortest time consequently to avoid wasting network resources.

Bayesian classifier works efficiently on some fields, and badly on some. The performance of Bayesian Classifier suffers in fields that involve correlated features. Feature selection is beneficial in reducing dimensionality, removing irrelevant data, incrementing learning accuracy, and improving result comprehensibility. But, the recent increase of dimensionality of data place a hard challenge to many existing feature selection methods with respect to efficiency and effectiveness. In this paper, Bayesian Classifier with Correlation Based Feature Selection is introduced which can key out relevant features as well as redundancy among relevant features without pair wise correlation analysis. The efficiency and effectiveness of our method is presented through broad.

This document summarizes a research paper on using correlation-based feature subset selection to improve spam detection accuracy when using a Bayesian classifier. The researchers introduce using feature subset selection to identify the most relevant features of spam emails while removing redundant features. This improves the accuracy of a naïve Bayesian classifier for spam detection from 65-74% to over 80%. It discusses how correlation-based feature subset selection works by selecting features highly correlated with the class (spam or not spam) but uncorrelated with each other. The researchers apply this method to a spam email dataset and achieve over 92% accuracy in spam detection using a Bayesian network classifier after feature subset selection, an improvement over using the classifier alone.

Spam
The document discusses spam, including its definition as unsolicited commercial email, statistics on its prevalence, and various types like email spam, web search engine spam, image spam, and blank spam. It also covers how spammers earn money, techniques for sending spam like using botnets and open relays, and anti-spam techniques like using filters and reporting spam messages. The conclusion emphasizes staying informed about spam characteristics to protect systems and data from potential dangers.
Modern Anti-Spam - Rejection, No Sorting (Version 2014)
The document discusses modern anti-spam techniques, specifically focusing on rejection instead of sorting. It notes that traditional sorting approaches interrupt user workflows, waste storage, and risk missing spam messages. Rejection provides a better solution by not accepting or delivering spam messages, instead sending rejection notices to senders. This avoids wasting resources and lost productivity while still informing senders of issues in a legally-compliant way. The document promotes the NoSpamProxy solution as a scalable gateway that can learn legitimate email patterns to better identify spam through rejection rather than sorting.
Analysis of an image spam in email based on content analysis
Researchers initially have addressed the problem of spam detection as a text classification or
categorization problem. However, as spammers’ continue to develop new techniques and the type of email
content becomes more disparate, text-based anti-spam approaches alone are not sufficiently enough in
preventing spam. In an attempt to defeat the anti-spam development technologies, spammers have recently
adopted the image spam trick to make the scrutiny of emails’ body text inefficient. The main idea behind
this project is to design a spam detection system. The system will be enabled to analyze the content of
emails, in particular the artificially generated image sent as attachment in an email. The system will
analyze the image content and classify the embedded image as spam or legitimate hence classify the email
accordingly.

Identification of Spam Emails from Valid Emails by Using Voting
In recent years, the increasing use of e-mails has led to the emergence and increase of problems caused by mass unwanted
messages which are commonly known as spam. In this study, by using decision trees, support vector machine, Naïve Bayes theorem
and voting algorithm, a new version for identifying and classifying spams is provided. In order to verify the proposed method, a set of
a mails are chosen to get tested. First three algorithms try to detect spams, and then by using voting method, spams are identified. The
advantage of this method is utilizing a combination of three algorithms at the same time: decision tree, support vector machine and
Naïve Bayes method. During the evaluation of this method, a data set is analyzed by Weka software. Charts prepared in spam
detection indicate improved accuracy compared to the previous methods.
A review of spam filtering and measures of antispam
This document discusses spam filtering and measures to reduce spam. It begins by defining spam as unsolicited email messages. It then discusses the problems caused by increasing spam volumes, such as becoming a security issue for businesses. Various types of spam are described, like text spam, image spam, and content-based spam. Methods for filtering spam are outlined, including collecting spam/anti-spam data, preprocessing to reduce noise, identifying bad senders, applying classification tools to specified content types, and storing results. Techniques for anti-spam filtering mentioned include white lists, rule-based filtering, content-based filtering, and pattern detection.

ACO-email spam filtering
This document summarizes a research paper that develops an ant colony optimization (ACO) approach for filtering spam emails. It begins by noting the negative impacts of spam and how machine learning techniques have improved spam filtering over traditional rule-based methods. It then provides an overview of how ACO has been applied to data mining problems. The document proposes an ACO-based spam filtering model called AntSFilter and evaluates its performance on a public email dataset compared to other classifiers like Naive Bayes and Ripper. The preliminary results found AntSFilter yielded better accuracy with smaller rule sets, highlighting important features for identifying email categories.
E spam
E-mail spam, also known as junk e-mail or unsolicited bulk e-mail (UBE), involves sending nearly identical unsolicited messages to numerous recipients by e-mail. Spam has grown significantly since the 1990s, with about 80% sent using networks of virus-infected computers. The legal status of spam varies by jurisdiction, though in the US it is legal if it meets certain specifications under the CAN-SPAM Act of 2003. Spam now averages 78% of all email sent and costs businesses billions each year.
