After reporting a hacker invasion on at least 1,400 devices, many of which belonged to journalists and human rights activists, companies like Google, Cisco and VMware joined Microsoft in legal support powered by WhatsApp against intelligence firm NSO Group , according to TechCrunch. The Israeli group develops and sells government access to its Pegasus spyware, allowing its customers to hack into its target devices.

The cloud acts as a support for the development of startups because it offers an elastic and scalable structure. Thus, business growth happens as it starts to deliver the same level of technology as large companies for a cost (investment) that the startup can assume.

This is possible in the cloud, as spaces, resources and tools are shared with other companies that are also in the same position. That is, the startup gains access to servers, operating systems and databases with cutting edge technology in a shared way for a price it can pay.

Although the subject of cybersecurity has already taken on much greater proportions than just the IT sector, this is where prevention actions must begin. More specifically, it is the IT manager's most important role in this regard.

First, it is necessary to guarantee a solid digital security structure, as well as actions aimed at improving this system: antivirus, VPN, firewall, Active Directory, backups, replication, penetration tests, systems programming, etc. In parallel, it is essential to invest in raising awareness at all levels of the company.

On the part of the company's managers, the risks must be clear. There is no security system that guarantees zero risk. Therefore, a contingency plan should be developed with a view to corrective actions in the event of an incident. This includes backups that are allocated outside the company environment on an external server (a cloud backup, for example), to enable restoration in the event of an attack.

In relation to employees in all areas, it is necessary to invest in training that involves not only awareness, but the implementation of internal safety standards. One of the main vulnerability factors of companies is human action - hackers work with social engineering to use people's behavior in favor of planned attacks.

Investing in technical and human issues at the same time is the key to a minimally reliable structure. However, it is crucial to maintain a culture of risk assessment and strengthening security systems - whether virtual or behavioral.

With this in mind, cybersecurity will become a more prominent topic in company discussions and the engagement of everyone will enable a more protected digital environment!

Basically, the implementation of systems in the cloud is carried out by the cloud provider in conjunction with the IT team of the contracting company and the software vendor.

The cloud provider performs environment provisioning, database installation and configuration, access security, communication tools, among other activities. And softwarehouses are responsible for accessing the environments created by the cloud provider and installing their applications in that environment.

All teams (IT staff, softwarehouse and cloud provider) must follow the approval and start of production to make sure the migration is successful.

Elias was a great example of a leader. At just 35 years old he already had his own IT team at a dealership in the city of São Paulo. Like many people today, he works hard and is still concerned with improving his knowledge. Currently he had taken some online courses on cloud resource management.

Everything was going well until he saw his routine change completely. The COVID-19 crisis has come to transform the way companies work. The virus spread quickly and the dealership he worked for was one of many who had to send their employees home to reduce the spread of the disease.

Machine learning - better known for its English language machine learning - is one of the great revolutions of technology. Along with other applications, such as the Internet of Things and Artificial Intelligence, machine learning has brought about profound changes in some sectors of the industry and helped to maintain innovation.

In partnership with the technology giant SAP, intends to use machine learning to solve one of the biggest problems of retailers: inventory control.

Monopoly power. Despite the potential for new start-ups, many aspects of the digital economy have become dominated by firms with monopoly power. For example, Amazon has cornered the market for online sales, meaning many firms have to go through the Amazon market place to reach consumers who go to Amazon out of habit. Similarly, Google and Facebook have all developed very strong brand loyalty and market share in their respective markets. This has made a few tech giants very profitable. WIth monopoly power, Google are able to charge high prices for online advertising and Amazon have the market power to undercut traditional booksellers.

Less community. A traditional bookshop can act as a focal point for local community. It may hold events, book signings and individuals may enjoy the experience of browsing physical books. With the digital alternative undercutting traditional firms, old fashioned bookshops are forced out of business. Although books may be cheaper, we have lost physical interaction between sellers and buyers which was an important aspect of the buying experience.

Addictive nature of technology. Whilst, in theory, the internet can save time, e.g. finding bus times is much easier with internet than paper copies, this time saved may be outweighed by the time we waste checking Facebook, twitter, internet searches. Also, the sheer volume of information can cause us to drown in information and lose sight of what we actually need. More choices do not necessarily lead to better outcomes. When faced with a bewildering range of outcomes, we can take time to decide and it becomes easier to procrastinate.

The promise of unrivalled wireless speed and consistency comes with a requirement for some changes in the way networks operate.

Providers will need to harness Software-defined Networks (SDN) to handle 5G’s throughput capabilities and scalability. With SDN, new functionality can be built and added on a software-based timeline, rather than the traditional (and slower) hardware timeline, ensuring networks are more agile and more efficient.

This is particularly relevant to IoT where more than 50 billion devices are predicted to be online by 2020 – SDN is the only viable way to ensure networks can secure and manage this additional traffic. Many forward-thinking organisations have already been extensively testing and deploying SDN as a means to lower costs and increase bandwidth across their corporate networks.

The other big thing about 5G in relation to Industry 4.0 is how 5G improves network latency, according to Anurag Lal, CEO of Infinite Convergence Solutions, “this provides the ability for applications, devices and entities to communicate in near real time, if not absolute real-time,” he said.

Most LAN networks use the “Class C” private IP address range. So in a typical network in a home or business the local IP addresses will start with 192.168. In a Class C network the first three groups of the IPV4 address must match exactly for the devices to be able to communicate. So it is common for local network devices to have an addressing scheme such as 192.168.1.1-254, with the first three octets matching and the last providing a unique address for each device.

What defines the different classes of IP addresses is the “subnet mask” which is associated with that class. Normally the subnet mask is the same in every device on a single LAN. If we look at the Class B private addresses above, we see that the default subnet mask is 255.255.0.0. The first two octets of this subnet mask with the “255s” indicate that those sections of the IPV4 address must match on all devices that need to communicate with each other. So in a Class C network the default subnet mask says that the first three octets must match exactly.

Public IP addresses will be issued by an Internet Service Provider and will have number ranges from 1 to 191 in the first octet, with the exception of the private address ranges that start at 10.0.0 for Class A private networks and 172.16.0 for the Class B private addresses.

It’s important for technicians to understand that IT personnel can choose to use any of the private address ranges for their LAN devices. It is not at all uncommon for a technician to be confronted with a client’s network where the local addresses are in the range of 10.0.0.1-254, and the subnet mask used is 255.255.255.0. This is an example of using Class A private addresses with a Class C subnet, which makes this a Class C network. It is the subnet mask that defines which “class” a LAN network’s addressing is using.
