Disaster recovery is the process, policies and procedures related to preparing for recovery or continuation of technology infrastructure critical to an organization after a natural or human-induced disaster. Disaster recovery planning is a subset of a larger process known as business continuity planning and should include planning for resumption of applications, data, hardware, communications and other IT infrastructure. A business continuity plan (BCP) includes planning for non-IT related aspects such as key personnel, facilities, crisis communication and reputation protection, and should refer to the disaster recovery plan (DRP) for IT related infrastructure recovery / continuity.
Disaster Recovery success is having a realistic and well understood set of objectives that are based on the business needs. This involves planning and preparation, from the business impact analysis, to understanding and quantifying risks, to classifying and prioritizing applications and data for recoverability.
Virtual Private Network (VPN) technology has become a preferred technology due to the security levels it provides during transmission of data. VPN Networks are primarily extended private networks comprising links across a shared public telecommunication infrastructure such as the Internet. In a VPN system, data is transmitted between two computers over the public network emulating a point-to-point link. Data packets are encrypted at the sending end and decrypted at the receiving end.
A virtual private network (VPN) can either be a remote access or site-to-site network - whatever the case; you'll need specific software and hardware to build a VPN. A VPN optimized router is used for scalability, routing, security, and quality of service. This piece of equipment is usually based on the Cisco IOS VPN software - you can find routers for many different networking needs. Small offices make use of them, as well as larger businesses. VPNs are used to connect offices and workstations together over a private network for various purposes.
In very basic terms VPN’s are used to support remote access to an intranet, as well as to support connections between multiple intranets within one organization. VPN’s are also used to join the networks between two organizations ultimately forming an extranet.
The Benefits of VPN’s
•It can be connected to by multiple access technologies including wireless and mobile
•VPN routers eliminate the congestion and routing headaches of managing networks
•VPN solutions easily facilitate the secure connection of remote users & road warriors

Spam is unsolicited and unwanted email. Other common names of spam are spam mail, bulk email or just junk mail. Today, spam has reached such monumental proportions that almost every other message we receive is spam. Protecting the inbox with anti-spam filter has become one of the barest necessities for almost all PC users.
To prevent e-mail spam, both end users and administrators of e-mail systems use various anti-spam techniques. Some of these techniques have been embedded in products, services and software to ease the burden on users and administrators. No one technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate e-mail vs. not rejecting all spam, and the associated costs in time and effort.
IT training courses can teach you just about everything you need to know about computers, and you can expect to become technologically savvy in a very short time. It is important to understand success lies in not only taking courses. You need to be sure the courses you take are from an accredited institution, and that you get the proper certification to prove to an employer that you have the skills they are looking for. In some cases simply having the knowledge and the ability to do the job is enough, but today many employers look for either experience or a degree to prove you can do what you claim.
