Cloud Computing (theITern)

Cloud Engineers in a Data Center

As taught at, Cloud refers to a network or internet that provides both public and private networks. Cloud computing is about storing our data in the internet from anywhere and accessing it from everywhere. Cloud engineers are IT professionals who goes into cloud to use infrastructure, services and tools available therein to build IT solutions that solve real life problems. They use these tools to administer, manage resources and secure Networks by taking advantage of Cloud’s Availability, Durability, Scalability, Resilience and other features.

Skills: Knowledge of the following cloud platforms can be useful: Amazon AWS, Google Cloud, Microsoft Azure, Oracle Cloud.

Artificial Intelligence(AI) & Machine Learning (ML) (theITern)

Artificial Intelligence (theITern)

Artificial Intelligence is a broad branch of Computer Science used to create intelligent machines that can recognize human speech, objects, learn, plan and solve problems just like humans. AI is becoming increasingly important within medicine as it supports doctors when diagnosing diseases. Looking at the educational sector, we would see how AI helps to individualize learning activities. AI is capable of converting spoken languages into texts and translating them into other languages using these methods:

  • You can program each individual instruction so that the machines solve tasks step by step.
  • You can use programs that learn data by themselves, this enables them to detect relevant data. This is known as Machine Learning.

Machine Learning

Machine Learning (ML) is a subset of Artificial Intelligence (AI) and it is the science of making computers learn and act like humans by feeding them with data and information without being explicitly programmed.  The system learns on its own, we only provide historical data.

A Typical example is the use of Snapchat to apply filters on our photos. Do you know how snapchat recognizes the photo on the screen and put filters on it? Snapchat does this using a technique called Facial Recognition which in turn uses Machine Learning (ML). The ML algorithms detect the features on your face like your eyes, nose, mouth and it knows exactly where they are and applies the filters accordingly.

Skills: Skills such as Python, Java are the highest demand.

Cyber Security (theITern)

This involves techniques that help in securing various digital component networks, data and computer systems from unauthorized digital access. Cyber security can be executed in several ways depending on the type of cyber-attacks you are prone to and networks you are connected to.

Types of Cyber-attacks

  • Malware Attack: This is one of the most common cyber-attacks like trojan, hardware and spyware
  • Phishing Attack: Here, the hacker sends fraudulent emails which are assumed to be sent from a legitimate source. This is done to install malware or to steal sensitive data like login credentials and credit card information.
  • Man-In-The-Middle Attack: Here, the hacker gains access to the information path between the victim’s device and the website server. The hacker’s computer takes over the victim’s IP address. By doing so, the communication line between the victim and the website is intercepted. This commonly happen with unsecured WIFI networks and through hardware.
  • Password Attack: This is one of the easiest ways to hack a system. Here, the victim’s password is cracked by using common passwords or by trying all possible alphabetical combinations.

How to Prevent Future Cyber-attacks

  • Install a Firewall Law: As the name suggests, it is a virtual law between your computer and the internet. Firewalls filters the incoming and outgoing traffic from your device to safeguard your network. Firewalls can be either software application or hardware re-inforcement.
  • Implement Honeypots: Just as flowers attracts bees, dummy computer systems called Honeypots are used to attract attackers. These systems are made to look vulnerable in order to deceive attackers and in turn defend the real systems
  • Use Antivirus Software: Cyber-attacks are not just confined to individuals but also to public and private companies, and attacks in such places are more deadly and results in colossal loses.

Types of Cyber-Attacks Companies Are Subjected To

  •  Advanced Persistent Threat (APT): In this form of attack, hackers gain access to information for a prolonged period of time in other to continuously gain confidential information of a company.
  • Denial of Service Attack (DOS): In this Type of attack, when networks are flooded with traffic, this could in turn leave legitimate service(s) requested unattended to.
  • Distributed Denial of Service Attack (DDOS): This is a variant of the DOS attack in which multiple systems are used to launch the attack.
  • SQL Injection Attack: This is when a hacker manipulates a standard SQL query in a database website. By doing so, the hacker can view, edit and delete tables from a database.

 To help with these, cyber security professionals are hired to work on identifying cyber-threats and securing a company’s network.

Data Science (theITern)

Data Scientist (theITern)

Data Science is the process of using data to find solutions to problems. Data on its own isn’t useful until it is turned into information. You get this information from analyzing your data to get insights. A Data Scientist gathers and processes data to convert its raw format to a cleaner format. Data Science goes beyond creating awesome visualization or writing codes, it is about using data to solve problems, by preparing data acquired, analyzing and modeling the data into useful solutions. Various roles offered to Data Scientists include Data Analyst, Machine Learning Engineer, Data Engineer, etc.

 Skills: These include Specific programming skills like Python, R, Java, Julia, Go, SQL, Scala, etc.

Software Development (theITern)
