How can infrastructure prevent information security problems in companies?

Sep 11, 2019


Information represents one of the most important assets for any business, and the amount of data companies have been working with is increasing every day. This makes information security a key issue by entering the list of the most important strategies for a well-assembled IT infrastructure.

 

Many of these data are personal information from customers (bank details, documentation, etc.), from suppliers and from the company's own business intelligence.

 

This information has a higher level of secrecy, requiring special attention in the protection, because if there are violations and / or leaks, the company's image may be compromised, and may even have to face legal proceedings.

 

And it is not only for reasons of invasion and theft of the information that we speak about this: accidents happen and there is a risk of total loss of stored data. That would be like working in the dark, with no direction.

 

To prevent this from happening in your company, we have prepared a post explaining how you can understand how a good IT infrastructure can prevent information security problems. Check out!

 

1. Performing regular data backups

A good IT infrastructure must have a shielded Data Center through a series of security policies. One is the automated backup system, which copies the company data and replicates it to auxiliary servers.

This strategy ensures access to information in cases of major server crashes, problems with the company's systems and / or some hardware, without interruption of business operations. In addition, the data is protected against partial and / or total losses in natural disasters or not.

Backups can be configured to be performed with a certain amount of time - once a day, once every three hours, etc. The frequency will depend on the level of importance of the data to the business and the risks it runs in the transactions. Banks are an example of the maximum level of security required in these situations.

Another setting that can be made is to select which data will have backup copies. In order to save storage space on servers and to have lighter files, managers can assess which data does not require backups, which can be copied less frequently, and which ones will have more frequency.

Regular data backup is a great way to ensure the protection of all confidential information from the company and its customers.

 

2. Providing limited access levels

Within the organization, managers and professionals from different departments will need to access the data to work, but that does not mean that this data can not be limited. A well-assembled IT infrastructure must be able to limit this access to levels of need.

For example, a finance manager must have a login and password that authorizes access to financial and accounting data. Already for a sales employee, only access to prices and descriptions of goods registered in the system may be enough to work smoothly.

These authorization levels can also be classified to allow access with freedom for insertion, deletion and editing of data or just for viewing them, not allowing any change.

Limiting access to only the necessary personnel ensures the reduction of risks of data breach. These restrictions can be made through a virtual infrastructure, which means that even employees who work remotely will have access to the information they need without the need to be present at the company.

Data access levels are customizable and can be changed to reflect current requirements at any time by individuals or group access, increasing information security in the enterprise.

 

3. Generating strong passwords for users

Although simple, passwords can be an effective tool in protecting information by preventing unauthorized access to your customers' financial and personal data.

Passwords can be configured by individual users, groups of professionals and by access levels, as mentioned in the previous topic, but it's no use doing just that.

In addition to the responsibility of employees and, above all, managers to protect the privacy of their passwords, IT managers must enforce the registration of complex (strong) passwords and change them from time to time to avoid risk.

Finally, passwords must be encrypted to make cybercrime actions as difficult as possible. With these measures, the company's IT infrastructure contributes directly to the enhancement of information security.

 

4. Encrypting important documents

Encryption is a security strategy that must go beyond password protection. The technology must also be used to make documents and company information illegible in cases of unauthorized access.

That is, to access a confidential document or more sensitive information in its decrypted form, duly authorized users must use a secret key or password. Only those users will be able to access this information, making it an effective way to protect your customers' information from day to day.

Recalling that a good encryption strategy can be supported by a wide range of operating systems, including the most up-to-date versions of Windows and Linux.

 

5. Upgrading server security

Anyone who works with server management through the Linux and Windows operating systems should always be aware of the available security updates. These updates should act to fix glitches, reduce or eliminate vulnerabilities found in the system, and enhance protection against intrusion.

Typically, most of the intrusion occurring occurs due to the lack of attention on the part of SysAdmin (responsible for the configuration and maintenance of the network servers), compromising the security of the information in the company.

To address this, the IT infrastructure should help enable the operating system to notify whenever an upgrade is available, and with manual or automatic authorization, allow it to be installed and configured automatically.

Whether through local servers, in the cloud or a mix of both, IT managers must act vigorously in building a well-protected IT infrastructure, creating a strong information security policy. After all, with the evolution of Big Data and Big Data Analytics technologies, information will be one of the most valuable assets the company can have.
