Since the beginning of the 21st century, the concept of Information Technology (IT) has shifted significantly. To the average person, IT no longer means possessing the capability to simply search the web using keywords, neither does it focus only on clunky desktop computers.
With technology’s evolution, IT has expanded to include numerous subsets — from programming to engineering to security to analytics and beyond.

The “information” aspect includes far more than obtaining sensitive data or protecting it. Systems now possess the capabilities for complex queries, extrapolating data, predicting future events, and even advising officials.
This access and wealth of knowledge inevitably led to the expansion of the IT security field. Are you familiar with the basics of cybersecurity? Read on to learn about the different types of IT security and how you can protect your business.
As usual, cyber attackers are already on the job even before we could type WFH! History will vouch that every disaster witnesses the unscrupulous targeting those in greatest need in a suddenly uncertain economy. Devious operators have sought to capitalize on the coronavirus outbreak in multiple ways. Employees struggling to cope with new and unfamiliar ways of accessing enterprise resources have become soft targets for phishing attacks. Such attacks usually invite them to click on guidance, download new network configurations, and other enticements to execute malicious content in messages, according to latest research.
Some attackers are preying upon expectations of support such as government assistance, directing the unsuspecting to malicious sites where victims will supposedly receive guidance on accessing disbursements or handling money transfers. Cybercriminals are also exploiting our hunger for information in this crisis to target us using malicious emails. Palo Alto Networks have identified malicious emails using subjects containing COVID-19 and related keywords carrying Remote Administration Tools (RATs) like NetWire, NanoCore, LokiBot, as well as other malware. Some mails promise coronavirus updates and business continuity plans, mimicking enterprise communication. Even the names of trusted global organizations are being used to send phishing emails, like Unicef Covid19 Tips app.

Who is a Cloud Engineer?In the past decade, we have seen Cloud Computing go from a ‘luxury-to-have’ to a ‘must-have’ necessity in today’s business landscape. With this dramatic shift, the demand for an IT professional who can take care of the migration process and perform cloud-related tasks also increased exponentially. This was the ‘ground zero’ for the Cloud Engineer job role.
Cybersecurity will no longer operate as an addendum in the world of information technology. As companies leverage emerging trends and move more toward cloud computing, cybersecurity will become a critical business functionality and will be an integral business process.
Data protections and PII are real-world concerns that are steadily creeping to the forefront as media coverage of data breaches affect our trust in brands. Making information security an operational necessity will position a business as a trusted entity and ensure smooth delivery of products and services.

Spreadsheets, word processing and databases. Limiting a modern PC to running these bread and butter tasks is like buying a Ferrari and driving it to the corner shop.
The question is, with a fast processor, a quick internet connection and a little imagination, what can a PC really do?
We've asked our writers to kick back and let their imaginations run riot. Security expert Jon Thompson inevitably got involved with spying and subterfuge, uber geek Mike Williams remote controlled his home PC with Twitter and joker Jamie Middleton decided to change the world. So read on and spare a thought for those PCs condemned to a life of office work.

Keep high-def YouTube videos
There are quite a few sites, plug-ins and apps that allow you to download videos from YouTube in Flash Video format. However, these can be quite a poor reflection of the originally uploaded video. In a large and increasing number of cases, you can also download high-quality and even high-definition versions of YouTube videos by slightly changing the URL.
It works like this. When you find a video you want to download, change the domain from www.youtube.com to www.youtubekeep.com and hit [Enter]. You'll go to a YouTubeKeep page that features download options for the video. Select what you want, click 'Download' and save the file. Don't be tempted to download illegal content and never redistribute what you've downloaded.
AI is different from, but related to, robotics, in which machines sense their environment, perform calculations and do physical tasks either by themselves or under the direction of people, from factory work and cooking to landing on other planets. Honavar says that the two fields intersect in many ways.
"You can imagine robotics without much intelligence, purely mechanical devices like automated looms," Honavar says. "There are examples of robots that are not intelligent in a significant way." Conversely, there's robotics where intelligence is an integral part, such as guiding an autonomous vehicle around streets full of human-driven cars and pedestrians.
"It's a reasonable argument that to realize general intelligence, you would need robotics to some degree, because interaction with the world, to some degree, is an important part of intelligence," according to Honavar. "To understand what it means to throw a ball, you have to be able to throw a ball."
AI quietly has become so ubiquitous that it's already found in many consumer products.
"A huge number of devices that fall within the Internet of Things (IoT) space readily use some kind of self-reinforcing AI, albeit very specialized AI," Cagle says. "Cruise control was an early AI and is far more sophisticated when it works than most people realize. Noise dampening headphones. Anything that has a speech recognition capability, such as most contemporary television remotes. Social media filters. Spam filters. If you expand AI to cover machine learning, this would also include spell checkers, text-recommendation systems, really any recommendation system, washers and dryers, microwaves, dishwashers, really most home electronics produced after 2017, speakers, televisions, anti-lock braking systems, any electric vehicle, modern CCTV cameras. Most games use AI networks at many different levels."
AI already can outperform humans in some narrow domains, just as "airplanes can fly longer distances, and carry more people than a bird could," Honavar says. AI, for example, is capable of processing millions of social media network interactions and gaining insights that can influence users' behavior — an ability that the AI expert worries may have "not so good consequences."

It's particularly good at making sense of massive amounts of information that would overwhelm a human brain. That capability enables internet companies, for example, to analyze the mountains of data that they collect about users and employ the insights in various ways to influence our behavior.
But AI hasn't made as much progress so far in replicating human creativity, Honavar notes, though the technology already is being utilized to compose music and write news articles based on data from financial reports and election returns.
Between continued talent shortage struggles, an evolution of what we’re requiring of field technicians, and continued pressure from customers to do more with less (and faster), more and more companies are turning to contingent workers to alleviate some of the burden of their service requirements. However, while we’ve come a long way in the acceptance of a contingent workforce as an option, there’s still some hesitation around relinquishing control, trusting “outsiders” to deliver your ideal customer experience, and properly managing the resources.

In 2019, I interviewed Charles Hughes, VP of technical services for Acuative, for the Future of Field Service podcast. Knowing not everyone of our listeners catch every episode, along with the substantial growth of our following since then, I wanted to revisit some of Charles’ valuable points about when and how it makes sense to turn to a contingent workforce. Charles has had a long career in field services and has experienced a variety of labor models including in-house only, outsourced-only, and hybrid labor models.
The Value of Contingent Labor
“If you take it down to the most basic components, leveraging a contingent workforce gives you flexibility, it gives you scalability and it gives you the ability to control the cost and still deliver high-quality levels of service,” says Hughes. For service organizations balancing the pressures of increased customer demands, more stringent SLA requirements, as well as an increasing shortage of talent, turning to a contingent workforce in some cases may be the only viable path to success.
The DHCP server must be configured with an appropriate scope of IP addresses and TCP/IP parameters for clients within each subnet. For example, the administrator must configured the DHCP server with an IP address range and subnet mask. The administrator must also set the lease duration time dependant on the organisations requirements. For example, if the organisation only has a limited number of IP addresses available and a large number of devices or clients that join and leave the network regularly, then the administrator may wish to reduce the time of the lease so that DHCP returns unused addresses for redistribution.

Finally, the administrator should configure the DHCP server to exclude static IP addresses present on the network from scope. For example, you may choose to exclude a certain IP address range from the scope of DHCP and utilise this address space for statically assigned servers on the network, if appropriate.
The interactions between client and server can be broadly compared to that of a TCP/IP connection. The client utilises a DHCPDiscover command to search for the DHCP server on the network. This is achieved by broadcasting the message to a specific subnet where the servers reside. The DHCP Server should pick up this command and issue a DHCPOffer command back to the client, which offers an IP address as configured by the administrator. The client then responds with a DHCPRequest command that requests the IP address offered and finally the server issues a DHCPPAck message to finalise the terms of the lease. This can be easily compared with shopping or an auction, as the seller you put out your product to a specific market, a potential buyer see’s the advert and comes back with an “offer” and you as the seller accept or decline and then the sale is finalised by the buyer presenting cash.
IT directors must possess a variety of problem-solving skills and an aptitude for organizational thinking, as technology deployments rarely go as planned. Additionally, professionals in this role are often responsible for setting their company’s IT budget, negotiating prices with third-party vendors, and overseeing other finance-oriented activities. Job seekers looking for hands-on roles that are solely focused on the technology itself might want to consider other professions, as IT directors spend a lot of time dealing with back-end administrative concerns.
Nearly all IT directors possess some sort of advanced degree in computer science, IT governance, or management information systems, as they must be able to make high-level decisions that align with their organization’s specific business requirements. In most cases, technology professionals work their way up the corporate ladder before pursuing a director position. With that in mind, how can aspiring students and mid-career techies set themselves up for success as an IT director?
