Why It Is Important To Learn The Concept Of CompTIA Security+ Certification

With the CompTIA Security+ certification, you can take your knowledge of network security to the next level and perform any number of security functions. The CompTIA Security+ certifications are offered by a professional organization that is comprised of a diverse group of IT experts who evaluate security related issues. In this manner, there is an educational requirement for those who wish to seek CompTIA Security+ certification, as they need to pass a challenging test in order to pass the certification exam.

CompTIA Security+ refers to two different types of exams, which range from easy to extremely difficult to pass. As with all IT certifications, the CompTIA Security+ exams are designed to test a variety of skills and knowledge to help make the passing of the exam as possible. With the rising threats to computer security, the passing of the CompTIA Security+ exam is even more important. This can help guarantee the security of any network, even for organizations that do not possess an extensive amount of money or personnel dedicated to IT security.

CompTIA Security+ offers three different levels of passing, each of which is more difficult than the previous one. While passing the CompTIA Security+ exam, you will need to be able to work in both areas of networks, and networks outside of them. Therefore, this makes the CompTIA Security+ exam the most demanding in the field of IT certifications.

The first type of CompTIA Security+ exam is the Network Internship Security Plus exam. This is based upon a project which has to be successfully completed in the practice lab environment, and the student must then successfully complete the labs. Once the student has successfully completed the labs, they must then submit an essay and a final exam, which are based upon the same topic as the practice labs, but with more advanced exams.

The second type of CompTIA Security+ exam is theNetwork Security Plus exam. This exam requires the student to complete the labs, with an emphasis on the lab which focuses on the real world situations in which a network is needed to be protected. With this kind of exam, the student needs to understand how to perform a variety of functions in both private and public networks. They also need to be familiar with a variety of technologies, including the ability to utilize firewalls and network monitoring software, as well as the knowledge of how to protect the system against attacks through various methods, including intrusion detection and response, firewalls, and the use of software viruses to secure the network.

The third type of CompTIA Security+ exam is the Network Security Plus exam. This exam focuses on a range of skills, which include working with security software that helps to maintain a complete picture of the system, as well as understanding how to implement security processes into the operation of a network. Students need to be able to demonstrate their understanding of firewalls, as well as provide insight into the various forms of attacks on computer networks, and how to block them.

Achieving success in the CompTIA Security+ exams requires an individual to understand both theory and practice. The exams are highly technical and require a student to understand both the theory behind the security, as well as the practical applications of the same. These exams also demand the students to do a great deal of reading in order to grasp the concepts.

CompTIA Security+ is just one of the many IT certifications available in the market today. This certification provides students with a significant amount of knowledge in computer security and also allows students to become better equipped to work in both the public and private sectors. For these reasons, it is important for students to understand how important the CompTIA Security+ certification are, before attempting to pass the exams.

Literature review and proposal as PL/SQL Developer

Literature review
It is vital to choose the right programming language that helps the programmer carry out transaction processing and the one that supports procedural constructs, and robust error handling (Wichmann, 1995). That programming language also needs to incorporated variable declarations and general high performance. The PL/SQL programming language has database basis, and it is also an application development language that supplements the SQL programming language with standard programming feature. It is the superset of SQL programming language. The features that this programming language adds to SQL include block structure, flow control statements and loops, customized error handling, structured data and variables and constant types (Feuerstein & Pribyl, 2014). It makes it possible for the one programming to store the compiled code into the database directly. With that possibility, the any number of users and applications can share the same functions and procedures. As a matter of fact, once the loading of the code takes place onto the memory, multiple users can use the same code simultaneously.

The users can also define triggers to enable the database execute them automatically in response to the specified events (Sharma et al., 2011). Pl/SQL is an exclusive product from Oracle Corporation and not an industry standard. The language helps in bringing efficiency to programming because if the user compiles it prior to runtime, there is high efficiency ensured in that code or program. It groups its statements into some units that we can refer to as block just like any other programming languages groups the statements into some units (Gupta, 2012). Those blocks can be anonymous or named as subprograms of procedures. There is the usage of a function in an expression, and it returns a valued top the expression before the invoking of a standalone statement. It then passes the value to the calling program using parameters only. It is also possible to nest those subprograms into one another and then into larger units known as packages. The daily responsibilities of a PL/SQL programming entail writing programs, queries, and functions so as to manipulate the structure and data of a database.

There is also a responsibility of querying databases and then generating reports that is vital to the decision-making process of an organizations or any business (Parker & Ottawa, 2006). PL/SQL ensures that those tasks take place in the required manner so as to deliver a high-quality code that lead to the delivery of high-quality reports or queries. Pl/SQL development takes place on the Oracle database, and the developers may also work with MySQL and the Microsoft SQL Servers, or any other database system (Hellstrom, 2015). It requires the SQL developer to have a thorough knowledge of SQL programming analytics ability and a strong logic. The software development arena requires that the developers report to the managers and the software development team leads. Because of that, it is a requirement that a PL/SQL developer handles the successful delivery of the development projects for software as well as support the production development. Those are the responsibilities that I will ensure that they take place while working in the i5 Tech Company as highlighted in my introduction and methodology.

The PL/SQL developer requires having active participation in software design and solutions while ensuring that he/she develops the company systems forward to deliver a high quality managed solution. PL/SQL language offers to the developer elements that are imperative to the software or application development task (Gupta, 2012). One of the elements includes organized code management packages that serve the purpose of making the locating of the code easy as well as its understanding and reuse. There is also the easy of top-down application design. That is because a separation between the public interface and the implementation if a crucial feature required for any package. That ensures that the programmer can code and compile a package with the absence of the body. When there is such vital separation of the public interface and the body, there is the possibility of developing an application in a modular fashion and not face bottlenecks. The bottlenecks arise due to incomplete implementation details in the code or application.

Both the bottom-up and the top-down development approaches are strategies that are useful for the processing of information and knowledge ordering (Dell Corporation, 2006). These tasks are vital in many areas such as software, scientific theories, humanistic, management, and organization. The top-down approach to PL/SQL development also known as decomposition, it is vital in breaking a system down to gain more understanding of the same regarding its compositional structure. In this approach, there is formulating of a system, making specifications although there is no detailing of any first-level subsystems. There is then the refining of the system into greater detail, and sometimes this may take place in many additional levels until the developers reduce the system into its base elements (Wile, 2002). It mean than the PL/SQL language helps in the reduction of the complexity of the task of development as in the case of bottom-up approach. The latter approach is where there is the piercing together of systems to form a more complex system meant for making g the original system be a subsystem of the emergent one.

The other powerful element of the PL/SQL is what the programmers call painless implementation changes because the language helps to eliminate the havoc or making changes to the subprograms. In many of the programming languages, making changes to a subprogram creates havoc with the other programs that might be referring it. With PL/SQL, there are no changes required in the dependent objects if only the there is the changing of the code in the package body (Tutorialspoint.com, n.d). It is also possible to ensure security and maintainability in the code when using this application language. It makes it possible to specify which of the items, types and subprograms that is private or public. Also, the ability to have in a package some private portions makes it impossible to access them publically. That is essential as it helps in protecting the integrity of that package as well as simplifying the maintenance.

PL/SQL also incorporates session-wide persistence of the public variables. That means the package public cursors, as well as the variables only, persist as long as the session is not over. They let the programmer to maintain the data across many transactions without the need for storing it in the database. They help in the storage of the values that have session-wide relevance like the debug/trace options. Better performance in PL/SQL language is possible through the loading of the package into the memory after the invocation of the packaged subprogram for the first time (Urman et al., 2004). There no disk I/O operations required for later calls to the subprograms that are in the package. All this translates to better performance than the SQL itself and other application programming languages.

Proposal
In the i5 Tech Company where I will be carrying out my research as an intern, I will have involvement in many tasks as highlighted in my introduction and methodology. Those tasks will relate to the PL/SQL development as I will be working as a PL/SQL developer in this company. I will have involvement in vital projects development with this language in question and in all those tasks I will be interacting with various teams of experts so as to understand what is in the requirement of me. Other tasks I will be in the requirement to carry them out alone while others I will be working with other teams or groups of professional for the purpose of quality and accountability. All those tasks have a division into five iterations including orientation, training, gathering and understanding the user requirements, coding, and testing and implementation. Those iterations have an explanation in the following paragraphs.

Orientation
The orientation session is where I will have the explanation of how the organization works, its structure, models of operation, management, working procedures and guidelines among others. I will have to know the limits of my duties and conduct so as not to have trouble in failing to adhere to the company rules and regulations regarding conduct and internship responsibilities. There will also be the issuance of the intern card that I will be using to identify myself as a legally taking my internship in the company.

Training
In the training phase where will be the task of helping me to know the areas that I will be handling during my internship in the company wherein, I will be taking my internship. There will be through training on the PL/ASQL coding principles and the rules that I ought to follow to ensure that I am in line with the international standards of coding in this language. There will be an assessment at the end of the training to test my understanding of the basics in taught during the training session as this will determine the project that company will assign to me.

Gathering and understanding user requirement
During the session of gathering and understanding the user requirements, I will have involvement in meeting and interacting with various end users of the application to have development. That will be helpful to me as I will understand the requirements clearly so as to code in light of those requirements. The development team will have to verify the data after analysis before giving me a go-ahead with the development. The company will assign to me one of the PL/SQL developers and one of the project development team members to help with the consultation services.

Coding
In the coding phase, I will begin the process of developing the required application that is the actual project development. It is the phase where I will have much work. It will require me to have regular contact with my supervisors so that I will carry it out in the required way and deliver unit within the specified time and quality.

Testing and implementation
In the testing and implementation phase, there will be the testing of the developed application for errors. The task will have performance in collaboration with the project development team and after the testing there will be the implementation of the developed application. It will be the last iteration in the company.

Literature review

Daily companies based on information technology are facing a lot of issues and computing challenges due to the data management. There is the wide usage of cloud and mobility, and it is opening up new opportunities for that information technology companies to be more service centric and productive. The database is the hidden workhorse that many businesses’ IT systems, storing critical business intelligence and bearing out hundreds to thousand so transactions each day (Cheung et al., 1996). Many companies are storing their information on relational databases, and they anticipate taking advantage of the emerging technologies such as XML or object-based databases. Instead to discarding the previous RDB or building non-relational data on it, it becomes better to convert the old data and applications onto a new environment (Maatuk et al., 2008). However, the question that remains is which of the databases is the most appropriate to migrate? That is the reason there is a need for an integrated method that handles database migration for it to be a success.

The method of migration needs to assist in the selection of the most suitable databases when comparing the databases that are available in the market. It should allow the development of the required applications to provide the required functionality and high performance than the previous one (Vitthal et al., 2013). A canonical model can be useful in the intermediate stage of data conversion and schema from the input database to the various output targets. Many researchers have been researching on the database migrations while focusing on different areas. There are many assumptions in most of the literature that restrict the successful migration. For the migration to a new database to be successful, there is a need for further normalization to third normal form (Premerlani & Blaha, 1994). Many of the literature assume key-based conclusion dependency with key attribute consistencies while another assumption is that the design often initial schema is okay. In Kronsys, the migration has to take place seamlessly, and I will have to ensure the application of the best methodology while working with the company’s database managers and data administrators.

In that research, I will prefer the application of an integrated method for database migration that can preserve the semantics and structure of an existing relational database to generate ORDB/XML schemas. The method also provides an effective way of loading data into the target databases without the loss of unnecessary redundancies. The method is superior to many of the approaches proposed in many kinds of literature, and it leads to three types of databases including an object-oriented, relational database, and XML schema. The method also helps to exploit excellent feature provide to the target outputs. Because there is heterogeneity among the three data models provided as outputs, the method makes it possible to develop a canonical data model (Callan, 2006). That canonical data model is useful in bridging the semantic gap that exists between those data models and consequently facilitate the migration process. The canonical data model does preserve and enhance the target database’s integrity y constraints as well as the data semantics that fit in with the target database characteristics.

The integrated method will consist of three phases including semantic enrichment, schema conversion and data conversion (Maatuk et al., 008). The first phase produces a canonical data model that contains much of the relational database’s constraints and data semantics that did not have an explicit expression in it. There is then the mapping of the canonical data model obtained into the target schemas of the second phase. The third phase is where the conversion of the relational database data into its equivalent in the new database takes place. There should be early designing of the system architecture and implementing a prototype to demonstrate that process that should show the success of the whole process before the actual migration takes place. In a nutshell, the integrated database migration project should entail three phases including semantic enrichment, schema translation, and the data conversion (Topor & Tanaka, 1997).

The semantic enrichment of database migration is where the analysis of the RDB to understand its meaning and structure takes place. That means you make the hidden semantics explicit. For Kronsys, the semantics enrichment phase will involve the extraction of data semantics from the old database and then representing in relational schema format. After that, there will be the conversion of the data into a much enriched canonical model. The schema translation will involve the translation of the canonical model produced in the previous phase into its equivalent target schema (Maatuk et al., 2007). There is following of the necessary rules during the translation that are not in the scope of this paper. The data conversion as the last phase will entail the conversion of the existing database data onto the format required by the target schema. Te canonical data model created in the previous phase is useful in guiding the conversion process.

Proposal
The paper focuses on tracking the internship at Kronsys Inc. in database migration so as to ensure that the migration process takes place seamlessly, and there is no disruption of the business processes. During my internship, I will ensure that the migration task goes on according to the requirements of the business. I will also be in the requirement to explore various modules of the new database and integrate them to benefit the company business operations. While carrying out an internship in database migration at Kronsys Inc, the internship consists of various phases like orientation, training, gathering or understanding requirements, and testing and implements the changes. These phases have explanation below through iterations.

Iteration 1 Orientation
The orientation session helps in understanding the company and their culture. During orientation at Kronsys Inc., the primary goal will be to explore the company and understand its vision and the mission statement. I will also have a good understanding of the focus and key players of the company.

Iteration 2 Training
In this phase, Training on the database migration essentials and operations will have an explanation so as to understand clearly my role in the entire process. During training, there will be a brief introduction to the ethics and standards of the organization plus the provision of real time examples to work on before actually project assignment.

Iteration 3 gathering requirements
After the training, I will analyze the project and obtain a proper understanding of the requirements. There will be the understanding of the project and requirements for the changes through the data gathering process and after analyzing the requirements, I will identify changes and perform analysis on the proposed changes. Later in this phase, there will be making a decision on the changes and obtaining of approvals.

Iteration 4 Test and Implementation
In this phase, there will be finalizing of the database changes and applying them to the existing system and then proper testing of the new database will follow to check the functionality is working properly. The testing will also serve the purpose of finding out if other services are effective because of the change implemented.
