Is Cybersecurity Awareness Month the event of the year?

Welcome back to the incredible and majestic Pandora FMS blog. In today’s post, we are going to deal with an event belonging to the month of October, that depressing month in which we become aware of fall, it is colder and someone keeps cutting short our daylight hours. If April is the month of flowers and November the month of the male mustache for testicular cancer, October is the Cybersecurity Awareness Month.

What is Cybersecurity Awareness Month?

Cybersecurity Awareness Month, which is commemorated every October, was created between the United States government and national industry to ensure that everyone had the necessary resources to stay safe and secure online.

Since its inception, under the supervision of the US Department of Homeland Security and the National Cyber Security Alliance, Cybersecurity Awareness Month has grown stronger and more widespread, reaching out to millions of users and businesses, and all types of corporations and institutions. Today, in 2021, it continues to make an impact, and not only in its country of origin, it already does around the world because, who would not join the cause of feeling more protected in these times we live in?

Cybersecurity Awareness Month: Origins

As we’ve explained, the National Cyber Security Alliance and the US Department of Homeland Security launched Cybersecurity Awareness Month in October as a shared effort to help Americans stay safe online. And they did it a few of years ago, at least all those that distance us from October 2004.

When a baby starts to walk, the first steps are short and simple. So were the early Cybersecurity Awareness Month awareness efforts. Most of them focused on giving recommendations on how to update the antivirus, at least twice a year. But little by little they increased their ambitions, their reach and their participation. For example, launching complex campaigns in the industry, involving clients, NGOs and even university campuses.

The organizers made it clear in these years that responsibility for cybersecurity problems is fully shared. From large companies to small users with their battered laptops, all of us must protect our digital treasures and always keep them under supervision.

The European Cybersecurity Month (ECSM)

What is European Cybersecurity Month? The European Cybersecurity Month works, like the American Cybersecurity Awareness Month, as an annual campaign devoted to promoting cybersecurity among users, companies and institutions. The only difference is that the European Cybersecurity Month is promoted by the European Union.

Throughout the month of October, safety information is provided online and awareness is raised through good practices. Activities are carried out around the entire continent: conferences, workshops, seminars, presentations, etc. Everything in order to make us finally aware of digital hygiene.

We must thank the European Union Agency for Cybersecurity (ENISA) and the European Commission for the fruitful month of European Cybersecurity Month, which, of course, has the full support of the EU Member States.

Some events of Cybersecurity Awareness Month

Like the Homecoming Week for high schools, Cybersecurity Awareness Month is also divided into different segments. We are going to list those established by the National Cybersecurity Alliance this year, 2021.

First week

The first week will be themed on creating strong passwords, using multi-factor authentication, backing up data, and updating software.

Only that way will we be able to realize how dependent we are on technology and reconsider the amount of personal and commercial data that we treasure on platforms located on the Internet. There, at the hand of any cybercriminal.

Second week

The motto? “You must be careful with emails, text messages, and chats opened by strangers and incognitos.” You are just one click away from a suspicious email, link, or attachment, to bother the hell out of you. Indeed phishing and digital scams in general have been on the rise since we began with this pandemic. Since we have the damn COVID among us, phishing attacks represent more than 80% of reported security incidents.

Third week

The third week of Cybersecurity Awareness Month will be focused on supporting, inspiring and applauding students who have chosen, or want to choose, a university career focused on cybersecurity. Whether they are teenagers, adults or confused kids who want to change fields of study. Cybersecurity is cool, youngster! It is fully growing and has space and credits for everyone!

Fourth week

This week we will try to make security a priority for companies more than ever. Incorporate security in products, processes, tools… Promote cybersecurity in employees and teams. Get cybersecurity in the minds of department heads until they themselves celebrate the vanguards and news of this discipline on a daily basis.

Together we check out the key concepts of systems and networks

In the middle of the information century, who has not surfed the Internet or used a computer, be it a desktop or a laptop? But do you really know what a computer is and what it is made of? and what about the Internet?

It is important to know at least the most superficial layer of something as important as computer systems and networks, and therefore, we are going to talk about the key concepts of these two topics.

A computer system is a device made up of the union of hardware and software, which allows the use of this system by a person, whether qualified or not, that depends on the purpose of the system.

But, what does “hardware” and “software” mean? Let’s talk a little more about it.

You can define as hardware the set of physical components that make up a computer system. We are going to define the main components of a computer system, although there are a few more:

• Processor: It is the component in charge of executing all the system programs. It is in turn made up of one or more CPUs.
• RAM memory: This component stores the data and instructions executed by the CPUs and other system components.
• Hard Drives: Information and content are stored here in computer systems.
• Motherboard: It is the component where the others are located, and works as a bridge for communication between them.

Well, now that we have a basic understanding of what hardware is, we move on to software.

Software are all the programs that run on a computer system, among which you may differentiate three types of software:

• System Software: It is responsible for the proper functioning of the operating system and hardware in general, such as device drivers.
• Programming software: They are tools whose sole purpose is the development of new software.
• Application software: It is any program designed to perform one or more specific tasks, for example video games or applications designed for business or education.

We already know what a computer system is, but without communication with the outside we are not making the most out of the potential that these systems have (which is a lot), so we decided to connect it to that abstract site full of information and services: the ‘Internet’.

Everyone knows the term “Internet”, but do we know what the “Internet” is?
We could say that the Internet is the great global network that unites all existing devices, allowing communication between all of them from anywhere on the planet. In turn, this large network is made up of other smaller networks, such as those of a country, city, neighborhood, etc.
Mainly, we distinguish three types of networks:

• LAN: It is the smallest network, a local area network, such as the one in work areas or the one you have at home.
• MAN: It is a somewhat larger network, being able to cover from neighborhoods to cities. They can also be the networks used by large companies for communication between their different offices.
• WAN: It is a network that connects countries or even continents to each other, not devices. We can say that the Internet is the ultimate WAN network.

Ok, we already know what the Internet is made of. But, how do devices communicate on these networks? There are systems used to identify each computer on the network, known as IP addresses. An IP address is, basically, the ID or identifier of a device, so it is unique and unrepeatable.

At the beginning, when the idea of an IP address was created, there were only a few dozen computers in the whole world, and this, as we already know, has gotten quite out of control since then. As a result of this increase, they decided to come up with a new concept, known as DNS (for its acronym Domain Name System).

What the DNS protocol does is, basically, translate the domain name that we enter, either in the web browser or in any other program, and convert it into an IP address, with which it communicates with the destination. Of course, all domain names are stored on DNS servers, scattered around the world to avoid connection overload, and to avoid slow name resolutions.

There are a large number of protocols, each with a different purpose. These protocols are grouped in layers, such as application, transport, Internet or access to the network, according to the TCP/IP model. But, that’s not all. We still lack another important concept in relation to communications between devices, what we know as “ports” of a computer system.

Imagine a road, if all the traffic that wants to enter a city only had a single road, what would happen? Well, the same thing happens in computing, and that is why these virtual ports exist.

These ports range from 0 to 65535, but the first 1024 are reserved for “important” protocols, such as the DNS protocol, which we have mentioned above, belonging to the application layer and that uses port 53 for both UDP and TCP connections.

TCP and UDP are two protocols belonging to the transport layer, whose main difference is that the TCP protocol is connection-oriented. That is, the TCP protocol makes sure that the data reaches its destination, while the UDP protocol sends the data, faster but less securely. This data may even not arrive or at least not fully arrive.

The protocols for web connections or HTTP/HTTPS, both belong to the application layer. Depending on which one you choose, it uses a different port. That is, for HTTP connections, port 80/TCP is used, although it is deprecated due to its lack of security, so the standard has become HTTPS connections, which use port 443/TCP and include a security layer based on SSL/TLS.

Connections made through safe channels or SSH, also from the application layer, use port 22/TCP, and thus we could continue with lots of other protocols.

Of course, these ports are a standard in the systems that receive the requests, the client that initiates the request can use any port that is not reserved to send the request and receive this data. As you can see, this is much easier to communicate with servers, although they can also modify their default ports, but the normal thing is that they do not do so if they want to provide a public service.

Finally, we are going to talk about a concept that, due to the pandemic, is the order of the day: the VPN.

As its name indicates (Virtual Private Network), we can define a VPN as a network “tunnel” that is created between client and server, where data are fully encrypted and sent through the Internet. The common use of VPNs is anonymity on the network, since the IP that is exposed is that of the VPN server, or, also, to be able to visit pages that cannot be accessed from the source country.
In the business environment, this tunnel allows direct communication between the client device with any other device in the network of that server, which allows access to an environment as if we were physically in the office of our company. It also allows access control and registration, which otherwise could not be done.
