Trusted by companies of any size, in every industry, including:
This man deleted his entire company with one line of wrong code.
Man accidentally ‘deletes his entire company’ with a one line of wrong code
A man accidentally deleted his entire company because of one mistaken line of code. Yes, you heard it right. According to the Independent, hosting provider Marco Marsala removed all traces of his company and the websites he manages for his customers after he accidentally told his computers to delete everything in its servers.
Marsala wrote on a forum for server experts called Server Fault, that he was stuck after mistakenly running destructive code on his own computers, which immediately went into a bit of a panic afterwards.
The command he mistakenly typed in was ‘rm -rf’. To put it simply: “rm” is short for “remove,” “r” means “this directory” and “f” means “force,” which in this context means “Do not open any dialogue boxes or trigger any warnings.” Normally the code will delete everything it is told to but because of the way it was written, no particular area was specified. Thus, it deleted everything on the servers.
In other words, this innocent-looking little five-character code actually tells the computer to delete everything, overriding all of the usual warnings that pop up when files are being deleted.
As a result of the wrong command, not only the sites got wiped off, but it also deleted all his backups because the drives that were backing up the computers were mounted to it.
‘All servers got deleted and the offsite backups too, because the remote storage was mounted just before by the same script (that is a backup maintenance script),’ he wrote.
Unfortunately for him, the other experts also couldn’t be of much help to him – basically informing him that he had possibly destroyed his whole business and was unlikely he would be able to recover any of the data.
“I feel sorry to say that your company is now essentially dead,” wrote a user called Sven. “You might have an extremely slim chance to recover from this if you turn off everything right now and hand your disks over to a reputable data recovery company.”
Another poster commented that: “You’re going out of business. You don’t need technical advice, you need to call your lawyer.”
“Well, you should have been thinking about how to protect your customers’ data before nuking them,” wrote one person calling himself Massimo. “I won’t even begin enumerating how many errors are simultaneously required in order to be able to completely erase all your servers and all your backups in a single strike.
“This is not bad luck: it’s astonishingly bad design reinforced by complete carelessness,” he added.

Need of Cyber Law: information technology has spread throughout the world. The computer is used in each and every sector wherein cyberspace provides equal opportunities to all for economic growth and human development. As the user of cyberspace grows increasingly diverse and the range of online interaction expands, there is expansion in the cyber crimes i.e. breach of online contracts, perpetration of online torts and crimes etc.
Due to these consequences there was need to adopt a strict law by the cyber space authority to regulate criminal activities relating to cyber and to provide better administration of justice to the victim of cyber crime.

Worm Attack: The Robert Tappan Morris well Known as First Hacker, Son of former National Security Agency Scientist Robert Morris, was the first person to be prosecuted under the ‘Computer and Fraud Act, 1986’. He has created worm while at Cornell as student claiming that he intended to use the worm to check how large the internet was that time. The worm was uncontrollable due to which around 6000 computer machines were destroyed and many computers were shut down until they had completely malfunctioned. He was ultimately sentenced to three years probation, 400 hours of community service and assessed a fine of $10500. So there must be strict laws to punish the criminals who are involved in cyber crime activities.
Hacker Attack: Fred Cohen, a Ph.D. student at the University of Southern California wrote a short program in the year 1983, as an experiment, that could “infect” computers, make copies of itself, and spread from one machine to another. It was beginning & it was hidden inside a larger, legitimate program, which was loaded into a computer on a floppy disk and many computers were sold which can be accommodate at present too. Other computer scientists had warned that computer viruses were possible, but Cohen’s was the first to be documented. A professor of his suggested the name “virus”. Cohen now runs a computer security firm.

Wang had openly boasted in internet chat rooms that he had also hacked over 30 other web sites too.
Preventive Measures For Cyber Crimes:
Prevention is always better than cure. A netizen should take certain precautions while operating the internet and should follow certain preventive measures for cyber crimes which can be defined as:
- Identification of exposures through education will assist responsible companies and firms to meet these challenges.
- One should avoid disclosing any personal information to strangers via e-mail or while chatting.

1. Requirement Analysis
The requirement analysis is the first step that we take into consideration during the web development process. We need to get into the nerves of the client to understand their requirement in detail. We prepare Minutes of the Meeting (MOM) along with our Scope. Understanding on the project, assumptions, clarifications and suggestions on each project. Client would provide their inputs on these points and from there we take things forward.
2. Building Specification
Spec building is a very important aspect in dealing with dynamic project. After analysing the requirement, we normally provide the spec of the project. If it is website development project, then we take into consideration the overall structure of the site, graphic user interface, navigation structure, front end and back end tools to be used etc., Once this is done, we proceed towards preparing the proposal which would include, project outline, project cost and schedule for the project delivery.
3. Design and Development
Once the project is declared and the initial deposit has been done, we start working on the prototype design for the website. During the process, there would be some suggestions from both the end on various design elements. We normally give options of two prototype design to the clients and once that is selected we proceed with html conversion for the same.
The next step would be inserting the content for static pages and start working on the dynamic part of the website on other hand.
4. Content Writing
Content writing plays a very important role in website development life cycle. We have very professional and experienced content writers who can write content based on each industry. Spell check and grammar check would be done and then implemented into the web pages.

6. Website Testing
Now the website testing team would come in to the scene and start their work to make the website development project an error free website. Website testing team would have the bug tracking system in place and keep shooting the errors available with the application and on other hand both designers and developers would fix all the errors available with application.
7. Website Promotion
Once the website project is completed and now its time for us to spend some time on making this website available with various search engines. The website elements should be optimized in such a way that it is getting listed in various major search engines like Google, yahoo, MSN, Bing and other search engines. Top ranking Keywords and Meta Tags need to be inserted in all the pages of the site.
8. Maintenance & Updations
Website updations need to be done very frequently to keep the website live. Whenever we do the modification on the website, the development life cycle need to be repeated again. For a huge website, it is recommended that you have the Web design & Web development, Testing and Copywriters in-house to update the website frequently without time loss.

In-Demand Technical Certifications for Beginners in 2016
Computer certifications exist for a single purpose: to provide a measurable account of a specific set of skills and/or product knowledge. If you are an expert, a certification is proof. If you are not yet an expert, the path you must take to become certified will provide you with the tools to become one.
There are many paths to certification and the first step is to do some research. Spend some time defining your current skills, deciding where you want to take your career, and then look at the certifications that are applicable to your goals.
There are several resources on this site that will help you decide what, if any, certifications are right for you to help you in crafting your personal certification strategy, here are some of the certifications that are expected to be most in demand in 2015.
Demand for project management skills continues to increase, especially as IT projects continue to increase in complexity. The PMP has emerged as one of the most in-demand certifications today, precisely because it demonstrates proficiency in managing those complex projects. The PMP test itself is rigorous, and maintaining the certification requires ongoing testing and effort, which makes the PMP certification all the more valuable to potential employers.
2. Cisco CCNA :
The CCNA is the first of three levels of certification offered by Cisco. The next two are the CCNP and CCIE. I would put all three on this list, but that would be redundant. The CCIE is one of the most respected certifications out there. Getting a CCNA is just one step to that goal. There are six different tracks to choose from for the CCNA and you have the ability to focus on a specific area by getting a specialist certification.
3.Certified Ethical Hacker (CEH) :
A Certified Ethical Hacker V8 is a skilled professional who understands and knows how to look for the weaknesses and vulnerabilities in target systems and uses the same knowledge and tools as a malicious hacker.
4. Microsoft Certified Information Technology Professional (MCITP) :
Microsoft certifications continue to be in high demand, because Microsoft continues to enjoy a strong presence in the corporate computing landscape. Like its predecessor the MCSE, the MCITP candidate can choose to specialize in a number of different domains, from desktop support to server administration to a number of specific applications, like Exchange and Lync. Some of the most valuable MCITP specializations include virtualization on the Microsoft Hyper-V platform, and SharePoint Server administration, to name a couple.
5.Certified Information Systems Security Professional (CISSP) :
The CISSP certification demonstrates knowledge of IT security across a number of domains, covering everything from network security to application security to formation and management of security policies for the enterprise. The CISSP also requires more than simply passing a test to maintain the certification - those who hold the certification are required to demonstrate on-going experience and education in the field of IT security over time.
6.Red Hat Certified Engineer (RHCE) :
According to a recent survey by jobs site Dice.com, 8 out of 10 respondents indicated that hiring Linux talent was a priority for 2012, and Red Hat Linux continues to make serious headway in the enterprise. The RHCE is a challenging certification to obtain, and requires advanced knowledge of a range of Red Hat systems administration tasks. The RHCE becomes even more valuable with the completion of any of a number of optional Certificates of Expertise, which cover a range of topics such as system clustering and virtualization.
7.Information Technology Infrastructure Library (ITIL) v3 Foundation :
The Information Technology Infrastructure Library (ITIL) Foundation certification demonstrates knowledge of the ITIL framework, which has evolved into the de facto standard for IT management in many enterprises. Companies are on the lookout for those who can demonstrate knowledge of ITIL and IT service management, especially as corporate IT organizations begin to treat IT more like a business by introducing service management standards and practices.
8.VMware Certified Professional (VCP) :
Virtualization has been a very hot area in IT for years now, and demand for IT professionals with virtualization skills will only continue to increase throughout 2012 and beyond. While there are a number of options for virtual platforms in today's marketplace, most private clouds (and many public clouds) in the enterprise utilize VMware as their preferred virtualization platform. The VCP demonstrates a level of proficiency in provisioning, maintaining and supporting VMware-based virtualization platforms, and indicates a level of general proficiency in virtualization as an IT skill.
9. CompTia Security+ :
Two years of networking experience is recommended for this certification so the true IT newbie might be in over their head with this one. However, security is a big issue and if you have the familiarity to take the one exam required, the Security+ cert works as a prerequisite for the MCSA and CNE.
10. CompTia's Network+ :
The Network+ certification is excellent for those who need general networking knowledge that is not vendor-based. It covers the basics of installing, troubleshooting, and configuring networking protocols and services. Most people need some experience before taking the $150 exam and an A+ certification is recommended. The Network+ combined with an A+ certification can be used as an elective towards a Microsoft MCSA.
