Lagos Nigeria Ebebe James Chibueze - Common types of Cyberattacks technology

Ebebe James Chibueze cyber security is the practice of defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. It's also known as information technology security or electronic information security. A compromised application could provide access to the data it’s designed to protect. Cyber attacks are an evolving danger to organizations, employees and consumers. They may be designed to access or destroy sensitive data or extort money.

Top Skills Required for Cyber security Jobs

·         Problem-Solving Skills

·         Technical Aptitude

·         Knowledge of Security across Various Platforms

·         Attention to Detail

·         Communication Skills

·         Fundamental Computer Forensics Skills

·         A Desire to Learn

·         An Understanding of Hacking

 

Common types of cyber attacks

1) Malware

Ebebe James Chibueze malware is a term used to describe malicious software, including spyware, ransom ware, viruses, and worms. Malware breaches a network through vulnerability, typically when a user clicks a dangerous link or email attachment that then installs risky software. Once inside the system, malware can do the following:

·         Blocks access to key components of the network (ransom ware)

·         Installs malware or additional harmful software

·         Covertly obtains information by transmitting data from the hard drive (spyware)

·         Disrupts certain components and renders the system inoperable

 

2) Phishing

Phishing is the practice of sending fraudulent communications that appear to come from a reputable source, usually through email. The goal is to steal sensitive data like credit card and login information or to install malware on the victim’s machine. Phishing is an increasingly common cyber threat.

 

3) Man-in-the-middle

Man-in-the-middle (MitM) attacks, also known as eavesdropping attacks, occur when attackers insert themselves into a two-party transaction. Ebebe James Chibueze once the attackers interrupt the traffic, they can filter and steal data. Two common points of entry for MitM attacks:

1. On unsecure public Wi-Fi, attackers can insert themselves between a visitor’s device and the network. Without knowing, the visitor passes all information through the attacker.

2. Once malware has breached a device, an attacker can install software to process all of the victim’s information.

 

3) Denial-of-service attack

A denial-of-service attack floods systems, servers, or networks with traffic to exhaust resources and bandwidth. As a result, the system is unable to fulfill legitimate requests. Attackers can also use multiple compromised devices to launch this attack. This is known as a distributed-denial-of-service (DDoS) attack.

 

4) SQL injection

Ebebe James Chibueze a Structured Query Language (SQL) injection occurs when an attacker inserts malicious code into a server that uses SQL and forces the server to reveal information it normally would not. An attacker could carry out a SQL injection simply by submitting malicious code into a vulnerable website search box.

 

5) Zero-day exploit

A zero-day exploit hits after network vulnerability is announced but before a patch or solution is implemented. Attackers target the disclosed vulnerability during this window of time. Zero-day vulnerability threat detection requires constant awareness.

 

6) DNS Tunneling

DNS tunneling utilizes the DNS protocol to communicate non-DNS traffic over port 53. It sends HTTP and other protocol traffic over DNS. There are various, legitimate reasons to utilize DNS tunneling. However, there are also malicious reasons to use DNS Tunneling VPN services. They can be used to disguise outbound traffic as DNS, concealing data that is typically shared through an internet connection.

Ebebe James Chibueze - How companies hire IT Specialists

Ebebe James Chibueze defines IT specialist, “It is a technical professional that is responsible for the implementation, monitoring, and maintenance of IT systems. Usually, companies hire IT Specialists to solve technical problems, such as computer systems, software, hardware, networks, cloud platforms, etc.”

Steps to Becoming an IT Specialist

The following are steps you can take to become an IT specialist:

Step 1: Earn a Bachelor's Degree

Ebebe James Chibueze says that a four year certification in a PC related field is the most widely recognized necessity for turning into an IT master. Applicable majors incorporate software engineering, data frameworks and programming building. Understudies in four year college education programs for the most part start by increasing a strong establishment in arithmetic, science and designing. They assemble expansive information on software engineering subjects in courses in information structures, numerical examination, information the board and programming dialects.

Ebebe James Chibueze IT specialist exploits PC research facility assets. Foundations that offer software engineering projects may likewise offer advanced PC labs for understudies. You should exploit these assets and the chance to get hands-on involvement in the projects and programming that are educated in classes and utilized in everyday activities of an IT specialist.

Also consider completing an internship. Since experience is an important part of finding employment in this profession, entry-level IT specialists may have trouble finding work. You can gain some practical experience and make professional contacts in the field by completing an internship with a local IT firm or the IT department of a company.

Step 2: Gain Professional Experience

As per an overview of occupation postings from monster.com in September 2012, IT master employments commonly require at any rate 3 years of involvement with the field. Propelled IT the board and security investigation positions may require at least 5 years of experience. Commonly, less experience is important at littler associations, so hopeful IT masters may see this as the best spot to begin their professions.

Ebebe James Chibueze says that IT Specialist acquiring affirmations are just thought of. In spite of the fact that accreditation isn't required to enter this calling, it might help show ability and experience to businesses. Moreover, bosses frequently require IT masters to have skill with explicit items. Sellers like Cisco, Oracle and Microsoft offer affirmation in their product items. Outsider associations, as CompTIA, additionally manage confirmation for numerous sellers. Confirmation essentials and prerequisites fluctuate by association, however accreditation is typically granted upon fruitful section of a test.

Step 3: Consider Earning a Master's Degree

A bachelor's degree may be the most common level of education required to become an IT specialist, but some employers prefer to hire applicants who have earned master's degrees in computer science or related areas. Also, master's degrees may create more opportunities for individuals seeking career advancement or higher positions in the field. Students in master's degree programs build on the knowledge that they have accrued during their undergraduate education and explore computer science theory and practice more extensively. They may take courses in computer graphics, algorithms, artificial intelligence, computational modeling and computer vision. Independent study and research in computer science, as well as a thesis, may also be required.

Ebebe James Chibueze - Information Technology used in innovative systems

Ebebe James Chibueze advances in computer-based information technology in recent years have led to a wide variety of systems that managers are now using to make and implement decisions. By and large, these systems have been developed from scratch for specific purposes and differ significantly from standard electronic data processing systems.

Ebebe James Chibueze - Too often, unfortunately, managers have little say in the development of these decision support systems; at the same time, non-managers who do develop them have a limited view of how they can be used. In spite of these drawbacks, the author found that a number of the 56 systems he studied are successful. And the difference between success and failure is the extent to which managers can use the system to increase their effectiveness within their organizations. Thus, the author suggests that this is the criterion designers and managers should jointly ascribe to in exploiting the capabilities of today’s technologies.

What can managers realistically expect from computers other than a pile of reports a foot deep dumped on their desks every other week? Ebebe James Chibueze everyone knows, for instance, that computers are great at listing receivables. But what about all the promises and all the speculations over the past few decades about the role of the computer in management? While there have been advances in basic information retrieval, processing, and display technologies, my recent study of 56 computerized decision support systems confirms the common wisdom that very few management functions have actually been automated to date and all indications are that most cannot be.

Types of Decision Support Systems

Ebebe James Chibueze while there are many ways to categorize computer systems, a practical one is to compare them in terms of what the user does with them:

  • Retrieves isolated data items.
  • Uses as a mechanism for ad hoc analysis of data files.
  • Obtains pre-specified aggregations of data in the form of standard reports.
  • Estimates the consequences of proposed decisions.
  • Proposes decisions.
  • Makes decisions.

Incidentally, it is interesting to note that external consultants developed the systems cited in my second, fifth, and seventh examples, while those of the first, third, and sixth were the creations of people acting as internal entrepreneurs through staff roles; only the fourth system was developed on direct assignment by the user. This same pattern of initiation of innovative systems by people other than the users was present in many of the 56 systems.

1. Retrieval only—a shop floor information system.

2. Retrieval and analysis—a portfolio analysis system.

3. Multiple data bases plus analysis—sales information systems.

4. Evaluating decisions using an accounting model—a source-and-application-of-funds budget.

5. Evaluating decisions using a simulation model—a marketing decision system.

6. Proposing decisions—optimization of raw materials usage.

7. Making decisions—an insurance renewal rate system.
