Types Of Software Licenses

Software Licensing

A software license is a legally binding agreement that specifies the terms of use for an application and defines the rights of the software producer and of the end-user.
All software must be legally licensed before it may be installed. Proof of purchase (purchase orders, receipts, invoices or similar documentation are acceptable) must be maintained by individuals or departments for all non-ITS provided software that is installed on a university-owned computer. 

Types of licenses

Proprietary license
Most software licenses are "proprietary" licenses, meaning the software publisher grants a license touse one or more copies of software, but that ownership of those copies remains with the software publisher. The user must accept the license before they are permitted to use the software.

GNU General Public License
These are agreements under which much "open source" software is licensed. End users may do things like change the source code, but any refinements of the software must also be made available under a GNU GPL license. 

Workstation licenses
These are licenses that permit the installation of an application on a single computer. You may not install the software on more than one machine unless you purchase a license for each additional machine. 

Site licenses
A site license permits the use of software on any computer at a specified site. Unlimited site licenses allow the installation of software on any number of computers as long as those computers are located at the specified site. 

Perpetual licenses
These are licenses without expiration dates, which permit use of the software indefinitely, without requiring a recurring fee for continued use. Most software that individuals buy for use on their home computers are perpetual licenses.

Non-perpetual licenses
These are licenses that "lease" the software for use for a specified period of time, usually annually or sometimes bi-annually. Users are required to remove the software from their computer if they cease paying the license fee.

License with Maintenance
Some license agreements allow the user to purchase "maintenance" or "software assurance" along with the original license fee, which entitles the user to receive new versions of the software for one to two years until the maintenance agreement expires.

 HABITS OF EFFECTIVE NETWORK SECURITY

Make Better Use Of Intelligence
Successful cybersecurity organizations have made a commitment to security intelligence. Compared to lower performers, the best organizations are six times as likely to have deployed a SIEM and four times as likely to invest in machine-readable threat intelligence. They're also six times as likely to use automated tools that alert them to new devices appearing on the network.
Instill Cooperation Between Network, Security, And App Teams
Bottom-tier organizations tend to be more siloed than their counterparts. Cooperation among network operations staff, security staff, and application teams is the name of the game in top-tier organizations, with 100% of them reporting this as a best practice compared to just half of bottom-tier organizations. The high performers are also nine times as likely to use integrated visibility tools and four times as likely to use integrated security tools.
Leverage DNS/DHCP Data
This is a growing differentiator between the security haves and have-nots. Close to half of top-tier organizations use DNS/DHCP data to discover new devices, compared to zero bottom-tier contenders. The best organizations are also three times as likely to use DNS logs for security purposes.
Automate Basic Tasks
Manual processes kill bottom-tier performance and the best orgs recognize that. Almost all top performers have automated routine tasks--including configuration management and compliance tracking. That's three to four times more likely than the average laggard organization.
Invest In Security Staff
This may seem like a no-brainer gimme, but the top-tier organizations are performing well because they're investing in their security staff. These leading orgs are three times less likely to report being understaffed for security and 58% say they have a dedicated incident response team, compared to 33% of the laggards.

Risks of social networking

What are the risks of social networking sites?
1. Social networking worms: Social networking worms include Koobface, which has become, according to researchers, "the largest Web 2.0 botnet." While a multi-faceted threat like Koobface challenges the definition of "worm," it is specifically designed to propagate across social networks
2. Phishing bait: When you realize Facebook has over 350 million users, it's still a significant number. To its credit, Facebook acted quickly, working to blacklist that domain, but lots of copycat efforts ensued (e.g., fbstarter.com). Facebook has since gotten rather adept at Whack-A-Mole.
3. Trojans: Social networks have become a great vector for trojans -- "click here" and you get:* Zeus -- a potent and popular banking Trojan that has been given new life by social networks. *URL Zone -- is a similar banking Trojan, but even smarter, it can calculate the value of the victim's accounts to help decide the priority for the thief.
4. Data leaks: Social networks are all about sharing.Even spouses sometimes over-share how much their significant other is working late on top-secret project, and a few too many of the details associated with said project. The resulting issues include the embarrassing, the damaging and the legal.
5. Shortened links: People use URL shortening services (e.g., bit.ly and tinyurl) to fit long URLs into tight spaces. 
6. Botnets: Late last year, security researchers uncovered Twitter accounts being used as a command and control channel for a few botnets. Twitter is shutting these accounts down, but given the ease of access of infected machines to Twitter, this will continue.
7. Advanced persistent threats: One of the key elements of advanced persistent threats  is the gathering of intelligence of persons of interest , for which social networks can be a treasure trove of data. 
8. Impersonation: The social network accounts of several prominent individuals with thousands of followers have been hacked.Furthermore, several impersonators have gathered hundreds and thousands of followers on Twitter -- and then embarrassed the folks they impersonate , or worse. 

Fraud:Fraud is deliberate deception to secure unfair or unlawful gain, or to deprive a victim of a legal right. Fraud itself can be a civil wrong , a criminal wrong or it may cause no loss of money, property or legal right but still be an element of another civil or criminal wrong.The purpose of fraud may be monetary gain or other benefits, such as obtaining a driver's license or qualifying for a mortgage by way of false statements.

Identity Theft: dentity theft is the deliberate use of someone else's identity, usually as a method to gain a financial advantage or obtain credit and other benefits in the other person's name,and perhaps to the other person's disadvantage or loss. The person whose identity has been assumed may suffer adverse consequences if they are held responsible for the perpetrator's actions. 

Loss of Privacy: Increasingly, governments, corporations, and other entities are collecting information about you that you willingly or unknowingly give out online. Even seemingly innocuous apps (like games or Facebook "quizzes") may now be collecting a wealth of data about you: Your name, your age, your gender, your physical address, email address, phone number, the particular device from which you access the Internet, your religious and political affiliation, relationship status, what you look like, where you are, who your friends and family members are, as well as your favorite foods, books, movies, hobbies.

Access to unsuitable content: It can be difficult to monitor what your child is viewing as they can access this material through any internet enabled device, including mobile ones such as a phone or tablet. Sometimes your child may stumble upon unsuitable sites by accident, throught apps they’ve downloaded to their mobile device or through links they’ve been sent by friends, chatting to others online, or even through inter-device communication systems such as Bluetooth or Apple’s AirDrop.

Cyber Bullyng: Cyberbullying is bullyng that takes place using electronic technology. Electronic technology includes devices and equipment such as cell phones, computers, and tablets as well as communication tools including social media sites, text messages, chat, and websites.
Examples of cyberbullying include mean text messages or emails, rumors sent by email or posted on social networking sites, and embarrassing pictures, videos, websites, or fake profiles.
