What is network security for a company

Introduction

Achieving different tasks within a modern enterprise usually requires the exploitation of various data within a computerized system.

However, it turns out that this system (otherwise the corporate network) is most often exposed to technical failures (failure), malicious software intrusions or simply handling defects. The data collected, stored and exchanged within the corporate network are however often confidential. This therefore requires managers and managers to ensure control of their network.

IT vulnerability management is a cycle that involves monitoring, sorting and continuously rectifying weaknesses in the system. This cycle includes security policy development, asset discovery and inventory, perimeter monitoring, and threat assessment and prioritization. Mappers and detectors for network, port and IP addresses, as well as alert systems, can be used for this purpose. Secured networks are often referred to as "networks".

Why vulnerability management?

With hackers constantly on the lookout for network weaknesses, vulnerability management is an essential part of a complete network security program. Used with firewall, antivirus, and intrusion detection-based peripheral solutions, vulnerability management solutions can help prevent unwanted access to sensitive systems and data.

A good vulnerability management system will help eliminate internal weaknesses, giving priority to protecting your most important assets. With an effective vulnerability management system in place, hackers will no longer be able to attack key systems and data, even if they manage to penetrate your network.

What is a business intelligence consultant?

What is a computer consultant? 

A computer consultant is a person who works on behalf of a company. Unlike a "typical" job, the consultant is not an employee of the company for which he works. Either the consultant has created his own company, or he is an employee of a company that is usually called a service provider . In both cases, the company for which the consultant works is called " the customer " in the common language of the trade. The following picture summarizes the situation.

Why do businesses use computer consultants? 

In a company, a job can be done by an employee of it or by an external person, a consultant . There is then a choice to be made for the firm that uses consultants for the following reasons:

The IT systems of medium and large companies are complex. The setting up and maintenance of these systems requires the intervention of specialized or experienced people accustomed to dealing with pointed problems;
A consultant brings a new look at the company he does not know. It provides new ideas that it implements when the customer deems it appropriate;
The call to a consultant provides flexibility to businesses. A consultant costs more than an employee but it brings a specific expertise and the company can easily separate if it does not provide satisfaction.

In summary, a consultant offers businesses a level of expertise, freshness, and flexibility.

What is the data collector?

The data collector is the application that collects and delivers the metadata that is then analyzed and presented in the graphical interface.

The data collector is a simple application installed on a server in your data center.which is in an IBM Cloud datacenter.You can install the data collector in minutes, and when you add the storage systems you plan to monitor, you get the capacity and performance information you need to monitor your data center. . Because the metadata that IBM support needs to review and resolve tickets is also collected, when you create or update a ticket, you can automatically download the logs for the affected systems. IBM support can access and review metadata to solve your problem.

Identification data for connection to storage systems

To add and collect metadata from storage systems that you want to monitor, you must provide the credentials of the storage systems that you want to monitor. Depending on the type of storage system you add for monitoring, you can specify the name and password of a user with privileges for metadata collection, or a user and an SSH key. The credentials that are provided are encrypted before being stored in the database for the instance, and the database is also encrypted. In addition, most storage systems support the creation of users with read-only roles that can not make changes to the storage system configuration.
