Data security

Security of IT systems

Security has always been and will continue to be a central topic for the operation of any IT system. Even if your system consists of a single computer, it is good practice to back up vital data, install antivirus software and make sure the computer is protected with a firewall, especially if it is connected to the Internet.

In larger IT systems, the problem of security has more aspects and is much more complex. The following solutions can be employed in multi-computer networks:

Ø  global firewall, often combined with a proxy server, to execute a security policy at all OSI layers,

Ø  IDS and IPS systems for detecting and blocking potential threats in selected points of the network (some threats can bypass the firewall),

Ø  antivirus software with central management, so that it can be controlled from a single console (update control, incident detection, etc.),

Ø  backup system across all the servers and workstations,

Ø  systems ensuring physical security of the hardware, such as video surveillance, fire protection systems, server room ventilation, etc.

Ø  fast response to service requests,

Ø  highly skilled and qualified team of IT professionals,

Ø  opportunity to buy computer hardware at a discount.

Note that the security of IT systems is a process rather than a one-time task.

Backups

Backup copies are an important part of data security management. In most cases, the loss or corruption of data stored on computers and servers poses a significant financial, administrative and legal problem for any entrepreneur or institution. Any loss of customer data, data from financial and accounting programs, stock management data, sales history data or payroll data (from the Płatnik ZUS application) can seriously hinder or completely obstruct business operation. The main causes of data loss or corruption include:

Ø  human error, where employees or unauthorised third parties accidentally or purposefully delete data,

Ø  software defect, where a data processing application malfunctions (e.g. a finance and accounting program incorrectly saving data),

Ø  activity of malware or other harmful software (viruses, worms, Trojans, etc.),

Ø  hardware defect, where data is lost due to hardware malfunction or failure (e.g. hard drive failure or computer failure caused by overvoltage or lightning).

To minimise the risk of data loss, you should ensure appropriate data protection. One of the methods for protecting data is copying sensitive data to redundant media at regular intervals. If the source data should be lost or corrupted, you will be able to recover it from the backup copies. Thanks to our extensive experience, we can design data protection procedures and a data backup system customised to your needs.

We also provide professional support in the recovery of data lost to the events listed above.

Data archiving

As you use your IT systems, you may experience considerable growth in the size of your electronic data, some of which is no longer needed for your everyday operation. In most cases, large amounts of data to process require higher performance of the processing systems and software. Unfortunately, due to a variety of reasons (including legal regulations), such data cannot be simply abandoned, which often generates extra expenses (e.g. to purchase more powerful computers, servers or software).

A solution to this problem can be a data archiving system. One of its tasks is to move old or outdated data to a separate archival storage system. Such a system is not intended for active and intensive operation, but offers large storage capacity and access to any historic data and its state at the requested time.

Our company can design and build or integrate a data archiving system customised to your needs.

Antivirus software

With the rapidly expanding Internet, using the benefits of the web means constant exposure to web-borne threats. These include malware in its various forms, which aims to corrupt or steal data and disrupt the operating system or applications.

Protecting your company's hardware, valuable data and results of employees' work should be one of the priority tasks in any well-planned IT resource management strategy.

Consult our experts to choose a tool that will work best for you and address your specific needs.

Firewalls

A firewall is becoming a must-have security feature. Depending on the scale, the optimal solution can be:

Ø  personal firewalls – installed directly on computers, often integrated with an antivirus program, anti-spam software, etc.,

Ø  firewalls installed on routers – both on small dedicated devices that connect a small network to the Internet, and on servers/PC computers running a Linux system or FreeBSD,

Ø  systems comprising or a firewall combined with a proxy and an antivirus suite – fully dedicated solutions installed on a single server or several servers running a Linux system or FreeBSD,

Ø  extensive systems with a hardware firewall, IDS and IPS system, and proxy firewall.

We will recommend a specific solution based on your needs.
