The topic of cybersecurity is gaining increasing attention from businesses, the media, and individuals, but unfortunately for the wrong reasons, as the main cause for this increase is the steep growth of the number of cyberattacks and their severity. Nevertheless, it is always extremely beneficial to raise awareness about this type of issue, regardless of the cause, since the best defense against these cyberattacks is you, the user, and the knowledge that you behold. Therefore, this article is an excellent starting point for people who want to be introduced to the cybersecurity world, understand and protect themselves from the most common threats/attacks they face or have faced on a daily basis, and gain insight into the future of this field.

The main goal is that after reading the article, you will feel keen to investigate more about this subject and become more aware of the threats that surround you.

What is Cybersecurity?

Certainly, you have already heard stories about the importance of cybersecurity or news stories about attacks on a company carried out by a particular cybercriminal. However, let’s take a step back and start with a simple definition. Cybersecurity is the practice of protecting data from malicious attacks by hardening computers, servers, mobile devices, electronic systems, and networks. It is also referred to as information technology security or electronic information security.

Why is it so important?

In this day and age, when data/information is one of the most valuable commodities, one can even argue that it is the most valuable one, the temptation to obtain it by any means possible in order to profit from it is growing exponentially. Another factor contributing to this increase is the easy access to tools and information that allow an individual to easily carry out cyberattacks that can completely undermine a company’s reputation. Therefore, now more than ever, cybersecurity practices must be applied to all areas and assets of an organization as the attack surface, i.e., the number of users, devices, and programs, continues to grow.

Most common attacks, and how to prevent them.

The attacks presented in this article are the ones you have most likely already dealt with. Therefore, we have chosen them with the intention of helping you recognize them more easily and advising you on how to better protect yourself from them.

Phishing, Smishing, and Vishing

Phishing attacks consist of messages, usually, emails, posing as trusted or reputable entities, sent by malicious actors with the intent to deceive a person into revealing (sensitive) information, installing unwanted software, or granting unauthorized access. Other forms of phishing include smishing, which occurs via SMS, and vishing, which occurs via phone calls.

How to defend against it as a user:

Be mindful of to whom you give your email address or phone number;
If you were not expecting that email or SMS, or if you don’t recognize the sender, just delete the email or SMS;
If you opened the email or SMS, because you were unsure of the content’s relevance, don’t save any files that may be sent as attachments without ensuring that they are safe;
Additionally, if there are any links present in the email or SMS, don’t click it the second you see it, first, verify with attention if the link redirects to a reliable source, and then you can consider clicking it;
If a seemingly reputable company asks for sensitive information on a phone call you were not expecting, say you can not attend now and call them yourself immediately after.

How to defend against it as a company:

Ensure that your employees receive proper training on a regular basis;
Establish and maintain bring-your-own-device policies;
Configure email spam filters and install anti-phishing software;
Enforce password policies and use multifactor authentication.

Malware

Malicious software is fraudulently installed on a machine with the specific intent to disrupt or damage it. The most common types of malware are viruses, worms, and Trojans.
