Internet Security Specialists Job Overview

Internet security generally falls under the jurisdiction of an engineering or systems administration department. A large company or government agency that deals with confidential information probably has its own Internet security department or team that devotes all its time and energy to Internet security. Many companies assign security tasks to the person responsible for system administration when they connect to the Internet. A smaller company could hire an Internet security specialist to log in and configure them with security systems and software.

A firewall is a system created to act as a protective barrier between the outside world of the Internet and the company. A specialist can instruct the firewall to restrict access or allow users to access. The Internet security specialist does this by configuring it to define the type of access that will be allowed or restricted.

First, Internet security specialists are tasked with monitoring the flow of information through the firewall. Security specialists must be able to write code and configure the software to notify them when certain types of activity occur. They can tell the program which activity to allow and what not to allow. They can even program the software to pay you or send you an email in case of questionable activities. Records are kept of all network accesses. Security specialists verify records and anything out of the ordinary. If they see something strange, they must judge whether the activity is innocent or harmful. Therefore, they have to investigate and carry out investigative work, perhaps even locate the user who initiated the action. In other cases, it may be necessary to create a new program to prevent the action from happening again.

Sometimes the Internet security specialist is responsible for virus protection or encryption and user authentication systems. Viruses are programs written with the explicit purpose of damaging a hard drive and can enter a network through infected email attachments or infected portable storage devices, such as CD-ROMs and flash drives. Encryption and authentication are used with any network activity that requires the transmission of confidential information, such as passwords, user accounts, or even credit card numbers. These professionals also ensure that your business meets all government security requirements.

Cable Television and Telecommunications Technician Nature of Work

Cable technicians typically start out as cable system installers. Installers prepare a subscriber's home for cable reception by connecting the cable system to one or more televisions or to one or more computers for high-speed Internet services. Installers explain to subscribers how to operate the cable system and how to update or downgrade their services. If a customer no longer wants the cable system, the installers remove it. Installers may also be responsible for maintaining the power lines that connect the main cable to small groups of houses and downpipes that are the direct lines of the cable to a subscriber's house. In general, installers do some troubleshooting if customers have minor problems with their cable assemblies.

Start-up technicians must have more advanced technical skills than installers. Start-up engineers continuously maintain the main or connecting line of the cable system. This work is very important because the external line is the main artery of a cable system and a malfunction can interrupt operation in a large area. Start-up technicians are responsible for correcting technical errors in the external line, in the power amplifier or in the booster.

Service technicians respond to problems reported by a subscriber. These technicians generally repair amplifiers, cables, or wires. You can also fix electrical errors in the cable system. They carry out preventive maintenance work by regularly scanning the cable system electronically. By identifying minor problems in advance, they can prevent serious cable failures later.

Not all cable television and telecommunications technicians work on site. The desk technicians, highly specialized electronics engineers, manage the repair structure of the cable system. They examine defective and faulty devices, repair them, record repairs and bring devices back into the field.

How to Become a Cable Installer

Step 1: meet the educational requirements

While people can only access the cable installation industry with a high school diploma, employers gradually prefer candidates who have completed a post-secondary electronics education program. This is due to the growing complexity and rapid expansion of the telecommunications sector. Individuals can gain valuable skills by enrolling in a two-year certificate or degree in electrical engineering or repair. An electronic repair certificate provides students with information on AC and DC circuits, applied mathematics and problem analysis, for example.

Step 2: Complete training in the workplace

After acquiring an apprenticeship and obtaining a basic level position, most cable installers complete an apprenticeship in the workplace, which can take up to three months. During this training, they learn the specific practices and equipment of their rental companies. Trainees perform subordinate tasks under the supervision of experienced technicians and face more complex tasks with experience. Some employers also send employees to training programs run by telecommunication technology organizations or device manufacturers.

Step 3: keep learning

As technology in this area changes rapidly, cable installers should seek training opportunities to keep up with progress. This may include reading equipment manuals and offering additional training to schools or industry organizations. The Society of Cable Telecommunications Engineers (SCTE) offers a range of technical courses on topics such as basic cable technology and cable networks. In fact, completing these courses is part of the training required to maintain SCTE certification.

Step 4: earn certification

Cable installers who want to demonstrate their knowledge, gain recognition of their skills or improve their career prospects can consider certification. In addition, some jurisdictions and employers require that these workers be certified. Various organizations, such as the Electronic Technicians Association (ETA) and the Society of Cable Telecommunications Engineers (SCTE), certify cable installers. For example, SCTE issues credentials for the installer of the broadband premises and the technician of the broadband premises. To get one of these certifications, you must pass an exam with 50 questions.

Who is system administrator?

The difference between a programmer and a system manager varies greatly between sites. Small tech organizations, where you can call them to have different roles, are the terms that can be used in exchange.

For large IT organizations with different departments, work addresses tend to be more clearly distinguished. System administrators carry out many of the day-to-day operations related to maintaining the core business information of the merger, while the software program focuses on maintaining the system itself. One reason to distinguish between obligations is compliance with the audit process, which often requires that no IT person be allowed access to sensitive data or sources. Examples of system administrators include Data Manager (DBA) and security manager.

Although the programmer’s ability is primarily in terms of hardware and computer programs, system administrators may have experience with applications. They always communicate directly with programmers and end users to ensure that the administrative aspects of applications are respected. This role is not to be part of the basic environment, but nevertheless the basis of their proper functioning.

In large IT organizations, the system manager monitors the software environment for business purposes, including daily maintenance of systems to make them work smoothly. For example, a database manager should ensure the integrity and effective access to the data stored in the data management systems.

Other examples of public administration systems may include:

Software installation

Adding and deleting users and managing user profiles

Maintain a list of sources of access to security

Management of storage devices and printers

Network management and connectivity
