Tech Terms: CDN

CDN is short for content delivery network. A content delivery network (CDN) is a system of distributed servers (network) that deliver pages and other Web content to a user, based on the geographic locations of the user, the origin of the webpage and the content delivery server.
This service is effective in speeding the delivery of content of websites with high traffic and websites that have global reach. The closer the CDN server is to the user geographically, the faster the content will be delivered to the user. CDNs also provide protection from large surges in traffic.

How CDNs Work
Servers nearest to the website visitor respond to the request. The content delivery network copies the pages of a website to a network of servers that are dispersed at geographically different locations, caching the contents of the page. When a user requests a webpage that is part of a content delivery network, the CDN will redirect the request from the originating site’s server to a server in the CDN that is closest to the user and deliver the cached content. CDNs will also communicate with the originating server to deliver any content that has not been previously cached.

The process of bouncing through CDNs is nearly transparent to the user. The only way a user would know if a CDN has been accessed is if the delivered URL is different than the URL that has been requested.

Many Businesses Use CDNs
When delivering large scale websites to a global audience, CDNs can reduce latency, accelerate site load times, reduce bandwidth consumption secure applications and even block data scrappers and other forms of spammers hitting your server.

Content delivery networks are used for B2B interactions and in serving content to consumers. Today, as more aspects of daily life move online, organizations use content delivery network to accelerate static content, dynamic content, mobile content, e-commerce transactions, video, voice, games and so on.

Tech Terms: Booter Services

A service offered by cyber criminals that provides paying customers with distributed denial of service (DDoS) attack capabilities on demand. According to this article on eWeek, Booter services, or Booters, are “Web-based services that do DDoS for hire at very low prices and are very hard to take down.”

Booters typically present potential customers with a Web front end that enables the end user to specify a Web site that they want the Booter service to target. Detecting and tracing Booters is complicated by the fact that the Internet service provider (ISP) that the Booter service appears to be hosted from is frequently not where the Booter is really located.

Booter services are frequently used by script kiddies and are responsible for many of the recent DDoS attacks that have received mainstream attention in the news.

Tech Terms: DDoS Attack

DDoS is short for Distributed Denial of Service. DDoS is a type of DOS attack where multiple compromised systems, which are often infected with a Trojan, are used to target a single system causing a Denial of Service (DoS) attack. Victims of a DDoS attack consist of both the end targeted system and all systems maliciously used and controlled by the hacker in the distributed attack.

How DDoS Attacks Work
In a DDoS attack, the incoming traffic flooding the victim originates from many different sources – potentially hundreds of thousands or more. This effectively makes it impossible to stop the attack simply by blocking a single IP address; plus, it is very difficult to distinguish legitimate user traffic from attack traffic when spread across so many points of origin.

The Difference Between DoS and DDos Attacks
A Denial of Service (DoS) attack is different from a DDoS attack. The DoS attack typically uses one computer and one Internet connection to flood a targeted system or resource. The DDoS attack uses multiple computers and Internet connections to flood the targeted resource. DDoS attacks are often global attacks, distributed via botnets.

Types of DDoS Attacks
There are many types of DDoS attacks. Common attacks include the following:

  • Traffic attacks: Traffic flooding attacks send a huge volume of TCP, UDP and ICPM packets to the target. Legitimate requests get lost and these attacks may be accompanied by malware exploitation.
  • Bandwidth attacks: This DDos attack overloads the target with massive amounts of junk data. This results in a loss of network bandwidth and equipment resources and can lead to a complete denial of service.
  • Application attacks: Application-layer data messages can deplete resources in the application layer, leaving the target’s system services unavailable.

Tech Terms: IT Degree

An information technology (IT) degree is a degree offered at the associate, bachelor, master and PhD level. The degree focuses on the branch of engineering that pertains to the use of computers to collect, store, and share and protect information.

At the associate’s degree level, typical courses include project-based information systems, Website database implementation, introduction to DHTML and Java Script, as well a mathematics based curriculum. The master’s level of education in Information Technology typically spans two years and offers a more focused and advanced field study. Courses at this level range from principles of software engineering to advanced algorithms and program language. The PhD in IT is the highest degree level offered, and is often focused on research.

An Information technology degree differs from computer science in that one is expected to understand and explore management and information theory.
