Security in POS systems

The security of pos systems has improved but still needs further refinements. The main sectors concerned include hotel and restaurant services and retail businesses.

Know about the POS Payment system security

POS payment systems continue to be subjected to cyber-attacks perpetrated by a growing variety of malware. Experts in computer security from Arbor Networks recently analyzed FlokiBot, a variant of the Zeus trojan used by the attackers to hit the banking systems. The Zeus malware was created around 2009 and spawned numerous versions and variants in the following years. The spread of Zeus proves that it is a well-proven platform that cybercriminals continue to rely on to create new malware targeting the banking sector.

Since 2013, the defense of pos systems has become a priority for cybersecurity teams. According to a Report, cybercriminals’ lives are getting harder and harder. “Both targeted petty thefts and attacks against large organizations leveraged static single-factor authentication systems. The attackers had to hone their weapons and work hard to compromise valid, non-default credentials with which to access IT environments. Furthermore, they have started to transmit stolen credentials from network support points rather than directly from the Internet.

Therefore, ensuring the security of the payment system in POS is imperative.

Recommendations for the security of POS systems

The security of pos systems has improved but still needs further refinements. Cybercriminals continue to innovate attack strategies as the stakes are always very high. All organizations, regardless of size, are encouraged to seriously consider conducting a thorough security analysis of the POS systems infrastructure to identify any existing compromises and to strengthen defenses against an adversary that continues to grow and expand its attacking skills. A good place to start is PCI-DSS compliance.

Business partners: A basic security measure is to reduce the threat front, with a focus on business partners: 97% of breaches with credential theft exploit legitimate access attributed to a business partner.

Dedicated machines: The machine running the POS software must be dedicated solely to this activity. It also needs to be hardened prior to commissioning to reduce the presence of open ports and limit application usage by allowing only those absolutely necessary for core functionality.

Strict connectivity to the internet: Connectivity must be subjected to strict controls, establishing a basic parameter of legitimate traffic that allows you to identify anomalous traffic and generate an alarm.

The voice of traffic: An effective monitoring system must be implemented, with the aim of identifying suspicious traffic coming or going to POS machines on the internal network and suspicious traffic coming or going to support systems or systems considered safe by the POS infrastructure.

Vigilance: After thorough testing, anti-malware applications should be aggressively used on POS machines to identify potential unknown malware.

Conclusion: Organizations need to employ multiple sensitive infrastructure monitoring techniques to identify unusual host and network activity. The classes of risk and complexity are variable, and the security activities can be more or less difficult depending on the functionality and segmentation of the network/processes. If the network is not properly configured to allow traffic only where it is really needed, the number of systems that can turn into support points for data theft increases, and attackers, therefore, have more possibilities and places to hide their traffic in an effort to extend the depth and duration of their campaigns.

Improving business logistics using barcode scanners

The large and frequent orders on the Internet, and a large number of products available in retail stores, place more importance on barcode scanners in logistics than ever before. In this sense, it is imperative that distribution centers develop new applications to improve this process.

Barcode Scanners in logistics markets

  • At the most basic level, a traditional area scanner is combined with a laser scanner to read the code for fixed or slowly moving objects.
  • The best range consists of an image-based reading system with a linear camera, and it supports high-speed applications for reading bar codes from various sides.
  • The third level falls between these two extreme levels, and there are now many applications that rely on increasingly complex generations of laser scanners.

How Barcode Scanner helps in Improving Logistics

Bar code scanner Read code for strict control: Distribution centers need to carefully manage inventory, including purchasing, shipping, and detailed inventory management.

Laser barcode scanners provide high read speeds with high-quality printed barcodes when the label is not damaged, but the code is very difficult to read under less than ideal conditions.

Image-dependent barcode scanners, on the other hand, have limited their use in large distribution centers due to cost and complexity, but they can improve reading speeds so far.

Today, a new generation of image-based leaders is revolutionizing the market and set to offer adequate speed at prices equal to or below the laser alternatives.

The quality of the printed barcodes varies greatly depending on the number of packages dealt with, the printing technology, the shape of the label, the place of origin, and many other factors. Laser scanners cannot read incorrectly printed codes.

Some laser scanners attempt to solve this problem by combining multiple scan lines to reconstruct the corrupted code.

More powerful

With rapid growth, distribution centers need to manage more and more packages, not just assets and destinations. All this increases the need for higher efficiency and faster read speeds.

Distribution centers with barcode reading errors can use line-based scanners. These readers capture high-resolution images of the package surface containing line-by-line code as the beam progresses, similar to how a document scanner works. It then analyzes this image to find and interpret a valid symbol, regardless of its orientation or position within the package.

Image-based barcode scanners have several advantages over laser scanners in the logistics industry. Firstly, the images are valued at more than 1000 laser scanning lines, so image-based scanners are more valuable information for barcodes. This feature allows you to read code that has been properly degraded due to corruption, orientation, or distortion.

To compensate for code corruption and light reflections from the beam, the analysis software can reconstruct important data from the readable portion of the image.

Conclusion: Prepare for the future

The further integration of distributions will place significant pressure on the capacity of reading systems, while the diversity of origins and destinations will continue to increase. Most travelers seek to reduce the cost of investing in capital goods. They want to make a long-term investment to prevent the equipment they buy from becoming obsolete in the short term. In this environment, the long life of the image-based system is a huge advantage.

Therefore, the future belongs to image-based reading technology. By learning more about moving to this new technology, fulfilment centers can avoid slow readings by lowering profit margins.

Evaluating the Quality of Point of Sale (POS) Software

Many times when in the middle of the night or early morning, we wake up abruptly and feel the urgent need to know how much  and where is what we have invested in our company, cataloged or translated into tangible and intangible products, ignoring the volume of sales, profit margin, Management processes, and purchasing value, additionally without knowing  who our customers are and much less our suppliers …, the nightmare, the terror of commercial failure stuns us and we rush the next day to buy a system accountant or something similar that a friend or close family member recommends to us to help us support and justify the investments of the company. it is there where we find ourselves in a dead-end from which not even the most daunting circus contortionist takes out.

But when we look for a computer solution according to the rules of our business, with the help and professional advice of an accountant or a professional with knowledge in administrative areas and IT solutions, who knows and intuits where we are going with the company, we can find a route or a good path to move forward and find prosperity and abundance in running the company.   

It is important to carry out an evaluation of the quality of pos software – POINT OF SALE solutions that exist in the market, before making the respective investment, based on the application of the following premises:

The parameters for Evaluating the Quality of Point of Sale (POS) Software

The parameters that allow you to create quality pos software are divided into two families, often correlated with each other:

External parameters that define the quality perceived by the user:

Correctness:  that is the ability of the pos software to do exactly what it was designed to do, in some “agile” development modes, it also means customer satisfaction;

Robustness: means the measure according to which a pos software behaves reasonably in the face of unexpected situations, such as errors, interruptions, resets, or exceptions of various kinds;

Reliability: the concept of a reliable system that is, there is little chance of serious malfunctions;

Efficiency: that is the factor that measures the probability of deterioration of performance or of inefficiency in the use of resources;

Usability: usability is a subjective quality that indicates the simplicity of the system on the user side;

Eco- compatibility: eco-friendly pos software takes into account the impact on the environment in the design.

Scalability:  a system is scalable if it can be adapted to different contexts and different degrees of complexity, without the need to redesign the entire structure.

Internal parameters that distinguish the quality of software on the development side:

Verifiability: a pos software can be defined as verifiable if its properties are easy to verify.

Maintainability: that is the ease with which a system can be modifiable and re-adaptable.

Repairability: parameter given by the simplicity through which errors can be corrected.

Evolvability: the ability of a system to evolve and be modified.

Reusability: parameter very close to the concept of evolvability but more oriented to the ability to reuse components of one pos software to create another.

Portability: a system with this feature is able to operate in environments other than the native one. The application of a portable system allows a considerable advantage in economic terms, as the application is transportable and can be used easily in different environments.

Conclusion

The quality of a pos software is defined step by step in the production process and requires the combination of different design and development methodologies.
