Malicious threats like malware, phishing, and social engineering pose ongoing risks to organizations. To help prevent data breaches and cyberattacks, it is important to take preventive measures such as using antivirus software on all devices, implementing strong password policies and two-factor authentication, filtering web content and email attachments, and keeping devices updated. Employee education is also key to avoiding human errors like falling for phishing scams or inadvertently disclosing sensitive information.
This document discusses web security and outlines some key terminology and issues. It defines internet security as protecting information by preventing, detecting, and responding to attacks. Some key points made are that 1 in 8 computers are infected with malware, spam and phishing attacks are common threats, and firewalls and antivirus software can help secure systems and block unwanted traffic. The document also provides definitions for common security terms like hackers, viruses, Trojan horses, and ransomware.
Cyber Security 101: Training, awareness, strategies for small to medium sized...Stephen Cobb
I developed "Cyber Security 101: Training, awareness, strategies for small to medium sized business" for the second annual Small Business Summit on Security, Privacy, and Trust, co-hosted by ADP in New Jersey, October 2013.
The presentation discussed web security issues including client-side, server-side, and data transmission risks and proposed SSL as a solution to encrypt data exchange between clients and servers, providing authentication, integrity, and confidentiality of data. It described the SSL architecture and protocols for encrypting records, negotiating keys during handshake, and alerting of errors.

How To Prevent Cyber Attacks | Types of Cyber Attack | What is Cyber Attack |...Intellipaat
In this session on how to prevent cyber attacks, you will learn what is a cyberattack, the types of cyber attacks, the motive behind the cyber attack, and how to secure your computer. This is a must-watch session for everyone who wishes to learn cybersecurity and make a career in it.
Network security involves implementing physical and software measures to protect a network from unauthorized access and enable authorized access. It aims to maintain confidentiality of data, integrity of data, availability of resources, and privacy of personal data. Key aspects of network security include encryption to scramble data, firewalls to control access to networks, and securing wireless networks through standards like WPA2. Common security processes also involve backing up data regularly, using access controls like passwords, and encrypting data during storage and transmission.
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.
Cybersecurity involves protecting internet-connected systems, hardware, software, and data from cyber attacks. It is based on the CIA triad of confidentiality, integrity, and availability. Cyber threats come from various sources and take many forms, including phishing attacks, SQL injection, man-in-the-middle attacks, malware, zero-day exploits, cross-site scripting, and password attacks. Organizations must implement appropriate defenses such as encryption, firewalls, anti-virus software, and user education to prevent and mitigate these threats.
Phishing involves using deceptive messages, usually via email or malicious websites, to trick users into providing sensitive personal information. It works by pretending to be from legitimate organizations like banks or retailers. Common goals of phishing are to steal usernames, passwords, credit card numbers, and other financial information. Phishing succeeds due to human vulnerabilities like clicking links without verifying the source, lack of awareness about threats, and weak security practices of organizations. Its negative impacts include identity theft, financial losses, and erosion of trust in online services. Users can help prevent phishing by verifying sources of communications, avoiding providing sensitive details via email, and being wary of unsolicited messages. A combination of user education and improved security technologies is

Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.
